Full textAbstract:
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building envelope. Through the estimation of the in-use Heat Loss Coefficient (HLC), it is possible to characterise the building’s envelope energy performance under occupied conditions. In this research, the estimation of the HLC of two individual residential buildings located in Gainsborough and Loughborough (UK) was carried out using an average method. This average method was developed and successfully tested in previous research for an occupied four-story office building with very different characteristics to individual residential buildings. Furthermore, one of the analysed residential buildings is a new, well-insulated building, while the other represents the old, poorly insulated semidetached residential building typology. Thus, the monitored data provided were filtered in order to apply the abovementioned average method. Even without fulfilling all the average method requirements for these two residential buildings, the method provides reliable HLC values for both residential buildings. For the house in Gainsborough, the best estimated HLC value was 60.2 W/K, while the best approach for Loughborough was 366.6 W/K. Thus, despite the uncertainty sources found during the analysis, the method seems promising for its application to residential buildings.

Purpose Sustainable retrofitting of aged buildings plays a significant role in reducing energy demands and greenhouse gas emissions. This study aims to assess the performance and effectiveness of energy retrofit measures (ERMs) for an archetype of aged multi-storey residential buildings. Design/methodology/approach The methodology consists of three parts, namely, a desktop study including the selection of a case-study building and identification of ERM options for the building; development of a computer model to simulate the building’s energy use in the baseline scenario and different scenarios of ERMs; and evaluation of the ERMs based on energy-saving rate. Findings Among the 13 ERMs tested, lighting-related ERMs were found to be optimal measures while window fin is the least suitable option in terms of energy saving. Based on the research findings, a two-level retrofitting framework was developed for aged multi-storey buildings. Research limitations/implications Future studies may take a similar approach of this study to develop retrofitting frameworks for other types of buildings, and further research paper can be extended to study retrofitting for buildings in a district or a region. Practical implications The findings of this study can serve as a reference for building owners to select effective ERMs for aged multi-storey buildings, which invariably exist in developed cities. Originality/value This study presents a pioneering work where an energy model and a building archetype were used to analyze the energy savings of a variety of ERMs that are applicable to aged multi-storey buildings.

Full textAbstract:
Building air tightness increased quickly in recent years as nearly zero energy buildings concept gradually drawn more attentions from the industry. Ventilation system plays an important role for the indoor air quality control in residential buildings with good air tightness. The energy consumption of the ventilation system is a significant part of the overall energy consumption of low energy residential building. The influence of the building air tightness on the energy consumption of ventilation system was not addressed sufficiently in previous studies. This paper analyses the quantitative relations between building air tightness, energy recovery efficiency and ventilation system control strategy. A mathematical model of the heating and cooling energy consumption in residential buildings is proposed, which takes building air tightness, energy recovery efficiency and control strategy of ventilation system as major input parameters. Equivalent COP of ventilation energy recovery system is proposed as an energy efficiency index of the ventilation system. It can be used as a criterion to decide the optimal design parameters of nearly zero residential buildings in different climate conditions.

Abstract The residential-building sector in India consumes >25% of the total electricity and is the third-largest consumer of electricity; consumption increased by 26% between 2014 and 2017. India has introduced a star-labelling programme for residential buildings that is applicable for all single- and multiple-dwelling units in the country for residential purposes. The Energy Performance Index (EPI) of a building (annual energy consumption in kilowatt-hours per square metre of the building) is taken as an indicator for awarding the star label for residential buildings. For gauging the EPI status of existing buildings, the electricity consumption of residential buildings (in kWh/m2/year) is established through a case study of the residential society. Two years of electricity bills are collected for an Indian residential society located in Palam, Delhi, analysed and benchmarked with the Indian residential star-labelling programme. A wide EPI gap is observed for existing buildings for five-star energy labels. Based on existing electricity tariffs, the energy consumption of residential consumers and the Bureau of Energy Efficiency (BEE)’s proposed building ENERGY STAR labelling, a grid-integrated rooftop solar photovoltaic (PV) system is considered for achieving a higher star label. This research study establishes the potential of grid-connected rooftop solar PV systems for residential buildings in Indian cities through a case study of Delhi. Techno-economic analysis of a grid-integrated 3-kWp rooftop solar PV plant is analysed by using RETScreen software. The study establishes that an additional two stars can be achieved by existing buildings by using a grid-integrated rooftop solar PV plant. Payback for retrofit of a 3-kWp rooftop solar PV plant for Indian cites varies from 3 to 7 years. A case study in Delhi, India establishes the potential of grid-connected rooftop solar PV systems for residential buildings. Techno-economic analysis of grid integrated, 3 kWp rooftop solar systems estimates a payback period from 3 to 7 years.

Full textAbstract:
Owing to stricter building energy requirements, future buildings will be characterized by low base loads and occasional high peaks. However, future building areas will still contain existing and historical buildings with high energy demand. Meanwhile, there is a requirement that future building areas should obtain energy from renewable energy sources, while existing buildings need to be transited to renewables. Therefore, the aim of this study was to develop an approach for modelling energy pathways for future Norwegian residential building areas by analyzing different energy supply systems. Several calculation methods were combined: building simulation, energy supply technology simulation, heat demand aggregation, and data post-processing. The results showed that the energy pathways would be very dependent on CO2-factors for energy sources, and it is hard to predict accurate CO2-factors. An increasing housing stock development would slightly increase the CO2 emissions towards 2050, although the new buildings used much less energy and the existing buildings underwent renovation. A constant housing stock would yield a 22–27% reduction of CO2 emissions by 2050. This showed that implementing stricter building codes had a lower impact on the total CO2 emissions than CO2-factors and energy technologies. The focus should lie on energy supply systems.

Full textAbstract:
Nowadays, energy consumption in buildings is one of the fundamental drivers to control greenhouse gas emissions and environmental impact. In fact, the air quality of urban environments can cause two main phenomena in metropolitan areas: urban heat island and climate changes. The aim of this work is to showcase how different building variables can impact the residential building’s space heating and cooling energy consumption. Buildings energy-related variables can be fundamental viewpoints to improve the energy performance of neighborhoods, especially in future urban planning. This work examines four neighborhoods in the city of Turin (IT): Arquata, Crocetta, Sacchi, and Olympic Village characterized by different morphologies and building typologies. In each neighborhood, residential building was grouped according to orientations and construction periods. A sensitivity analysis was applied by analysing six building variables: infiltration rate, window-to-wall ratio, and windows, walls, roofs, and floor thermal transmittances. The energy consumption for space heating and cooling of residential buildings and local climate conditions were investigated using CitySim Pro tool and ENVI-met. The challenge of this work is to identify the building variables that most influence energy consumption and to understand how to promote high-energy efficiency neighborhoods: the goal is to identify the “ideal” urban form with low consumption and good comfort conditions in outdoor urban environments. The results of this work show a significant connection between the energy consumption and the six analyzed building variables; however, this relationship also depends on the shape and orientation of the neighborhood.

Full textAbstract:
Accurate prediction of buildings’ lifecycle energy consumption is a critical part in lifecycle assessment of residential buildings. Longitudinal variations in building conditions, weather conditions and building's service life can cause significant deviation of the prediction from the real lifecycle energy consumption. The objective is to improve the accuracy of lifecycle energy consumption prediction by properly modelling the longitudinal variations in residential energy consumption model using Markov chain based stochastic approach. A stochastic Markov model considering longitudinal uncertainties in building condition, degree days, and service life is developed: 1) Building's service life is estimated through Markov deterioration curve derived from actual building condition data; 2) Neural Network is used to project periodic energy consumption distribution for each joint energy state of building condition and temperature state; 3) Lifecycle energy consumption is aggregated based on Markov process and the state probability. A case study on predicting lifecycle energy consumption of a residential building is presented using the proposed model and the result is compared to that of a traditional deterministic model and three years’ measured annual energy consumptions. It shows that the former model generates much narrower distribution than the latter model when compared to the measured data, which indicates improved result.

The paper is oriented on searching for possibilities, which would approach the existing residential buildings to zero energy buildings. Existing residential buildings must remain competitive in the real estate market. Therefore, this paper is focused on progressive solutions, which application will significantly contribute to the approach towards zero energy balance. I have done my research on a concrete residential building in Bratislava. Scientifically I analyze the individual phases of improvement of this residential building. Firstly, I calculate the annual energy balance for individual phases, then I evaluate them. The basic improvement phases of energy balance of concrete residential building: insulation, regulation of heating system, application of heat pumps, application of solar collectors and photovoltaic modules. The scientific outputs are presented by well arranged graphs. Each improvement phase is analyzed in detail with introduced risks and contribution for energy balance. I will point out the problem of incorrect architectural design from the energy point of view, which remains a serious obstacle for further possible improvements with modern technological systems. By this research, I want to point out new possibilities for existing residential buildings.

Full textAbstract:
In the early 2000s, the Korean government mandated the construction of only zero-energy residential buildings by 2025 and for non-residential buildings from 2030. Two decades since the start of building energy policy enforcement, Korean experts believe that it is time to evaluate its impact. However, few studies have systematically and extensively examined the energy consumption characteristics of the non-residential building stock. In this study, a framework development is implemented for defining non-residential prototypical office buildings based on Korea’s first large-scale non-residential building survey result from the Korea Energy Economics Institute (KEEI). Then, a detailed building energy model of the defined prototypical building is constructed to verify the model’s energy estimation against observed energy consumption. As an application of the model, a case study for energy policy evaluation utilizing the constructed prototypical building model is presented. Every researcher and county may have their own circumstances when gathering definition data. However, by using the best available representative data, this suggested framework may result in informed decisions regarding energy policy development and evaluation. In addition, the mitigation of greenhouse gases from buildings may be expedited.

Abstract A building energy model is a simulation tool which calculates the thermal loads and energy use in buildings. Building energy models provide valuable insight into energy use in buildings based on architecture, materials and thermal loads. In addition, building energy models also must account for the effects of the building’s occupants in terms of energy use. In this paper we discuss building energy models and their accuracy in predicting energy use. In particular, we focus on two types of validation methods which have been used to investigate the accuracy of building energy models and on how they account for their effects on occupants. The analyzed building is P + M located in the climatic zone 4, Sânpetru / Braşov. We have carried out a detailed and exemplary energy needs analysis using two methods of analysis.

By combining the green ecological wisdom on traditional Chinese residential buildings, this paper summarized the ideas that can be used for references and applications in modern green energy-saving design. In addition, in view of the inherent shortcomings of traditional residential buildings, this paper proposed a green energy-saving design method for traditional residential buildings based on 3D modelling technology, which is complementary to the traditional ecological construction concept. Based on the establishment of a 3D building information model of traditional residential buildings, the optimal solution for the energy-saving design of green buildings is found through energy-saving adjustments to the building space structure and building spacing parameters.

To assist in the implementation of carbon peaking and carbon neutrality in China, due to the contradiction between the increasing energy consumption of residential buildings in China and the higher energy efficiency goals, this paper illustrates that the energy consumption constitution of residential buildings in the whole life cycle and then puts forward comprehensive energy efficiency strategies. With literature and statistical data, the main part of building energy consumption lies in the materialization and use phases, which both will be continually increasing, and divided into energy utilization and waste. By inducing the energy consumption in the use phase, the energy consumption of residential buildings can be further classified into the energy consumption of indoor environments, residential behavior, and public facilities, where the internal factor of continuous increase are all elaborated. Via the analysis of energy waste causes, this paper constructs a model of energy consumption in residential buildings, reveals that the key to energy efficiency in residential buildings lies in scientific decision-making, lifestyle improvement, and appropriate energy efficiency technologies and measures adoption, and points out that promoting building energy efficiency through the whole life cycle of buildings and building activities is needed to achieve carbon compliance and carbon neutrality.

Full textAbstract:
Over the last two decades, the residential building sector has been one of the largest energy consumption sectors in New Zealand. The relationship between that sector and household energy consumption should be carefully studied in order to optimize the energy consumption structure and satisfy energy demands. Researchers have made efforts in this field; however, few have concentrated on the association between household energy use and the cost of residential buildings. This study examined the correlation between household energy use and residential building cost. Analysis of the data indicates that they are significantly correlated. Hence, this study proposes time series methods, including the exponential smoothing method and the autoregressive integrated moving average (ARIMA) model for forecasting residential building costs of five categories of residential buildings (one-storey house, two-storey house, townhouse, residential apartment and retirement village building) in New Zealand. Moreover, the artificial neutral networks (ANNs) model was used to forecast the future usage of three types of household energy (electricity, gas and petrol) using the residential building costs. The t-test was used to validate the effectiveness of the obtained ANN models. The results indicate that the ANN models can generate acceptable forecasts. The primary contributions of this paper are twofold: (1) Identify the close correlation between household energy use and residential building costs; (2) provide a new clue for optimizing energy management.

This paper targets the future energy sustainability and aims to estimate the potential energy production from installing photovoltaic (PV) systems on the rooftop of apartment’s residential buildings, which represent the largest building sector. Analysis of the residential building typologies was carried out to select the most used residential building types in terms of building roof area, number of floors, and the number of apartments on each floor. A computer simulation tool has been used to calculate the electricity production for each building type, for three different tilt angles to estimate the electricity production. Tilt angle, spacing between the arrays, the building shape, shading from PV arrays, and other roof elements were analyzed for optimum and maximum electricity production. The electricity production for each household has been compared to typical household electricity consumption and its future consumption in 2030. The results show that installing PV systems on residential buildings can speed the transition to renewable energy and energy sustainability. The electricity production for building types with 2–4 residential units can surplus their estimated future consumption. Building types with 4–8 residential units can produce their electricity consumption in 2030. Building types of 12–24 residential units can produce more than half of their 2030 future consumption.

The building sector represents one of the most energy-consuming worldwide and a great part of its consumption is accounted for residential demand for space heating and cooling. Although it is necessary to promote the buildings energy efficiency, energy flexibility is also of paramount importance to optimize the balance between demand and supply. In fact, an energy flexible building is defined as able to change, in a planned manner, the shape of its energy demand curve, electrical and thermal, while the comfort of the end-users is still guaranteed. Objective of this work is to exploit the energy demand management ability of different buildings composing a cluster, when their aggregated demand derived from electric heating systems (i.e. heat pumps) is subject to demand response (DR) strategies. Users with different occupancy profile are considered. By supposing to be able to activate the energy flexibility of the single building with thermostatic load control, different scenarios of cluster composition are evaluated in order to provide guidelines to implement optimal strategies for energy flexibility exploitation without drawback effects connected to the event.

Energy conservation and human thermal comfort enhancement in buildings is a topical issue of modern architecture and construction. The innovative solution of this problem makes it possible to enhance building ecological and maintenance safety, to reduce hydrocarbon fuel consumption, and to improve life standard of people. The requirements to increase of energy efficiency in buildings should be provided at all the stages of building's life cycle that is at the stage of design, construction and maintenance of buildings. The research purpose is complex analysis of energy efficiency in operated high-rise residential building. Many actions for building energy efficiency are realized according to the project; mainly it is the effective building envelope and engineering systems. Based on results of measurements the energy indicators of the building during annual period have been calculated. The main reason of increase in heat losses consists in the raised infiltration of external air in the building through a building envelope owing to the increased air permeability of windows and balcony doors (construction defects). Thermorenovation of the building based on ventilating and infiltration heat losses reduction through a building envelope allows reducing annual energy consumption. Energy efficiency assessment based on the total annual energy consumption of building, including energy indices for heating and a ventilation, hot water supply and electricity supply, in comparison with heating is more complete. The account of various components in building energy balance completely corresponds to modern direction of researches on energy conservation and thermal comfort enhancement in buildings.

The residential sector is one of the largest energy-consuming sectors in Taiwan. Taiwan applies building codes and appliance standards to reduce the total energy demand for buildings, especially for façade design. Some research studies demonstrate that design decisions regarding the envelope shape have a direct effect on a building’s energy performance. This paper presents a comparative study of four façade design strategies for low-rise residential buildings by combining energy performance and architectural creativity.

Full textAbstract:
Buildings account for about 40% of the global energy consumption and this energy demand is projected to continue growing over the next few decades. Residential buildings are responsible for over 60% of this consumption pattern with commercial buildings being responsible for the remainder. While residential building energy consumption constitutes about 20% of the total consumption in the developed world, it constitutes up to more than 50% in the sub-Sahara African region. The growing consumption of energy has raised concerns over the impacts on the environment, supply difficulties, and depletion of resources. In efforts toward addressing these concerns, the need for effective management of energy resources and adequate planning for energy infrastructure cannot be overemphasized within the building industry in general and the residential building sector in particular. Toward this end, it is necessary to ensure that high quality and high-resolution information on the consumption of energy in buildings is made available. Unfortunately, in many countries within the sub-Sahara African region, building energy consumption information is hardly ever readily available. This study seeks to make a contribution toward this facet of the literature at the greater regional level in general and particularly, in Malawi, a country located in the southern part of Africa. With a grounding in the context of urban residential buildings, the study identifies the key energy end-uses, investigates the proportional mixes of the end-uses and the energy sources and, finally, establishes the periodical per capita energy consumption amounts for the end-uses and the typical residential building unit.

Nowadays office buildings are faced with high and long-term cooling demand with grate heat recovery potential. In low heating demand office buildings not all of recoverable excess heat can be utilised, so it forces to search the consumers beyond the energetic boundary of office building. One of more promising way is supplying residential building by excess heat to meet the space heating and domestic hot water demands. Proposed cross-building cooling-to-heating energy flow allows transferring and utilizing excess heat from office building in residential as a useful heat. This solution creates the flexible and sustainable environment and meets the energy challenges of the future, in line with current energy trends and policy.

Full textAbstract:
Existing buildings are the massive percentage of the building stock, and therefore, are the key to improving efficiency; buildings account for an enormous share of the climate change crisis, and approximately 40% of the world total energy consumption (McArthur & Jofeh, 2015).
The Egyptian stock of buildings includes about 12 million buildings. 60% of these buildings are residential. The final electricity consumption of the residential buildings in 2010 was 51370 GWh and increased in 2014 to reach 62441 GWh. Thus the share of total energy consumption was 18.8% in 2010 and increased to reach 21.55% in 2014 ("Technology Roadmap - Energy efficient building envelopes.", 2013). Therefore, the residential sector plays an important role in the mitigation of energy consumption crisis, which is expected to increase.
The research field and initiatives in Egypt on the green buildings and green buildings retrofits are rare and, if existing, are weakly applied. Unlike in developed countries, there is a large research on building retrofits, e.g., the Residential Property Assessed Clean Energy (R-PACE) program and the weatherization assistance program (WAP) of the department of energy (DOE). Both are examples of the incentives to green building initiatives globally.
This paper discusses the challenge of greening the existing residential buildings in Egypt by demonstrating an analysis of the motives and the barriers to applying green measures in the Egyptian market.
The research methodology comprises the analytical-comparative method. In the analytical part; the paper identifies the current situation of the residential sector energy consumption in Egypt, and the benefits of greening existing buildings for tenants, investors, and owners.
In the comparative part, the current situation of Egypt's Green Market Business Case is compared with the international one, discussing the challenge of greening the residential buildings. The paper summarizes the opportunities to improve the building energy efficiency, incentives, and policies that are developed to address significant financial and technical awareness to building efficiency. These policies will help enable critical market actors to make decisions to promote energy efficiency in existing buildings.

A two floor residential building in Tianjin as the research object was studied in this paper. The software eQUEST was carried out to simulate residential buildings energy consumption, and to explore the annual total energy consumption of the residential building, which was influenced by air conditioning heating modes and the building orientations. The air conditioning and heating system modes used to simulate including the heat pump air conditioning, air conditioner & heat sink and radiant heating & heat sink. The simulated building orientations include east, west, south and north. The transformation of the sunshade direction could be obtained by changing the building orientation. The indoor design temperature in summer was set at 26°C, while winter design temperature was set at 18°C. As the result of the energy consumption simulation study showed that, the annual total energy consumption achieved the minimum when heat pump type air conditioning heating system was adopted. When the effected factors such as air conditioning heating system, indoor heat source condition, window size and some other factors which influenced energy consumption were constant, the simulation results might be found that the building orientation had a small influence on the building energy consumption.

The paper is oriented on the design of energy concepts of zero energy buildings. In the first phase of concept is important the good architectural design in terms of energy. In the residential building for four flats I calculated the annual energy consumption by computer simulation in the current condition and in the proposed reconstruction. I demonstrate that the unbalanced architectural design of flats in a residential building causes also after reconstruction a significant difference in energy consumption. This means that when developing energy concept of zero energy building the first essential step is energy efficient architectural design, taking into an account the energy aspects. The next step is to the use of technological aspects: passive and active use of solar gains, effective ventilation systems with heat recovery and new generation of heat pumps. For the formation of zero energy buildings is essential application of described progressive trends in the development of energy concepts.

The paper presents the application of an International Green rating system LEED’s in a developing country. It focuses on significant environmental, energy, and water issues faced after construction. The rating conducted was on a multifamily residential building located in Askari 14, Rawalpindi, Pakistan. The building's construction was complete; hence The LEED v4 for Building Operations and Maintenance manual was used for performing Green rating. The rating works on the bases of point allotment scheme for building’s operational and environmental features such as energy use efficiency, water use efficiency, sustainable material usage, and more. The selected structure is constructed by implementing standard building techniques to which Pakistan adheres, which never inculcate aspects of environment and energy reduction. The cumulative score of all LEED’s components after rating is 40 out of 110, which grants it the rank of certified. Where the building performs poorly can be attributed to the fact that there were no LEED’s Accredited Professionals involved in the design phase of the case study. From the results, possible solutions are discussed in the paper to integrate the concept of sustainability in constructed buildings.

Abstract The energy consumption in the world due to economic development, rising population, and technological developments is growing, which has led to an increase in global warming. Therefore, there is a strong need to develop new strategies to reduce energy consumption. Buildings account for about 40% of global energy consumption. Since occupancy time in residential buildings is longer than in commercial and office buildings, residential buildings have a more significant impact on energy consumption. Due to this issue, efforts are being made to optimize energy consumption in residential buildings. Evaluating the performance of a building through building certificates that include as-designed and in-operation is essential for improving energy efficiency. Building energy simulations must be performed before construction to ensure that energy consumption in buildings is acceptable. However, it is observed that the energy consumption of the building after construction is higher than what was designed. This difference is defined as the energy performance gap, which indicates extra energy consumption or failure to comply with energy standards in the operation of the building. There are several reasons for the increased energy consumption of an operating building compared to the designed model. So far, studies have been conducted to determine the factors affecting the energy performance gap, but it is necessary to analyze these studies comprehensively. This article investigates the causes of energy performance gaps and ways to reduce this difference through a comprehensive literature review study. In this way, it is possible to achieve solutions in the building certification criteria that minimize the difference in energy consumption between the as-designed model and the in-operation mode of the building. This article can help decision-makers select the certificate that best fits their purposes.

Abstract As the goal-setting in the European Green Deal is to reach carbon neutrality by 2050, great efforts have been put to improve the energy efficiency in residential buildings. As residential buildings are towards high energy efficiency, building envelopes are becoming better thermally insulated and systems are becoming more energy-efficient. Therefore, the role of occupants in the actual building performance is becoming more important. However, contradictions exist between the uncertainties caused by occupant behaviour (OB) and the over-simplified consideration of OB in building design. Therefore, this paper aims to present a state-of-the-art of how OB is represented in residential buildings. Through a literature study, this paper first reviews different occupant behaviours and how they are considered in the design and operation of high-performance residential buildings. Modelling methods are categorized by occupant activities. In addition, behavioural theories in the application of analysing building performance are reviewed. How the behavioural theories are integrated with state-of-the-art building technologies is outlined. Finally, challenges and suggestions for representing the interaction between occupants and buildings in the design and operation of residential buildings are discussed.

Electrical energy usage in buildings is a challenging issue because many old buildings were not originally built to achieve energy efficiency. Thus, retrofitting old buildings to net-zero buildings can benefit both the owner and electric utilities. In this study, the BEC (building energy code) software was used to evaluate energy aspects of retrofitted buildings in compliance with Thailand’s building energy code to achieve a net-zero energy building. In addition, economic aspects were also studied to verify the feasibility for a project’s owner to invest in a retrofitted existing building. An existing residential building in Thailand was used as a case study. The results in terms of energy after retrofitting existing buildings into net-zero energy buildings show that the total energy consumption can be reduced by 49.36%. From an economic perspective, the investment cost for a retrofitted building can be compensated by energy saving in terms of discounted payback period (DPP) for approximately 4.36 years and has an IRR (internal rate of return) value of 19.23%. This result evidences the potential in both energy and economy for a project’s owner to invest in a retrofitted existing building in compliance with the building code, with potential for implementation with benefits on both electrical utilities and the project’s owner.

Due to the chronic shortage of energy-related analytical data and disintegration of building energy regulations, numerous existing residential buildings in Petra (Jordan) and many cities worldwide suffer from poor building energy design. This paper aims at investigating the potential of applying energy-saving standards in order to improve the whole-building energy consumption of low-rise residential buildings in mild and dry climate zones. Representative buildings were selected based on a field survey. Proposed strategies focused on applicable solutions such as envelope components, and energy-related systems were set. The models were created using Autodesk Revit, and then the results were generated by the EnergyPlus engine. The findings showed that the application of building energy standards greatly impacts the overall energy end-use, where up to 30% reduction can be achieved by applying the Jordanian code, and up to 45% by applying the American standard. This work provides guidance for the residential building industry and policymakers in Jordan and many other countries with similar building characteristics and climate zones.

Abstract Sustainable design is a design strategy that aims to improve environmental quality as well as the quality of a building’s internal atmosphere by limiting negative consequences on the structure and the surrounding environment. Several new building envelope technologies and concepts have been presented as solutions for enhancing indoor comfort and lowering environmental impact during building life cycles. In Egypt, the high sensitivity to temperature fluctuations resulted in an increase in power usage to meet the necessary cooling loads. Energy simulations are a common way to improve a building’s energy efficiency. Design Builder program with the Energy Plus simulation engine was used for energy analysis of the building. This was confirmed by comparing the energy efficiency performance of selected case studies of buildings with and without a sustainable development approach. In two parametric series, an existing prototype of a residential unit module will be utilized to evaluate energy performance, co2 emission and thermal comfort. It has been discovered that a building envelope with a variety of characteristics may provide the inhabitants with the highest level of residential comfort. In comparison to similar-sized structures, the building façade decreases energy usage by 80% related to CO2 emissions, according to this study.

Full textAbstract:
The residential sector consumes about 50% of the electricity produced from fossil fuels in Saudi Arabia. The residential energy demand is increasing. Moreover, a simple building energy performance assessment framework is not available for hot arid developing countries. This research proposes an energy performance assessment framework for residential buildings in hot and arid regions, which focuses on three performance criteria: operational energy, GHG emissions, and cost. The proposed framework has been applied to three types of residential buildings, i.e., detached, attached, and low-rise apartments, in five geographical regions of Saudi Arabia. Design Builder® was used to simulate the energy demand in buildings over a whole year. Four types of efficiency improvement interventions, including double-glazed windowpanes, triple-glazed windowpanes, LED lighting, and split air conditioners, were introduced in 12 combinations. Overall, 180 simulations were performed which are based on 12 intervention combinations, three building types, and five regions. Three performance criteria were evaluated for each simulation and then aggregated using a multi-criteria decision analysis method to identify the best intervention strategy for a given building type and a geographical region in Saudi Arabia. Each building type with interventions consumes higher energy in the western, central, and eastern regions and consumes a lesser amount of energy in the southern and northern regions. The proposed framework is helpful for long-term planning of the residential sector.

Grid-connected photovoltaic (PV) system efficiency can be maximized with building demand matching. Computer simulations were used to investigate the priorities of energy efficient measures commonly used in residential and commercial buildings in Thailand that decreased the electricity demand while producing load profiles that matched the unique output profiles from PV systems. Residential and commercial buildings in Thailand were modeled in existing conditions. Then they were made compliant with ASHRAE energy standard requirements which can reduce electricity consumption 16-36% in residential buildings and 8-19% in commercial buildings. With energy efficient design measures, electricity production from PV systems could satisfy the remaining consumption and peak electricity demand reduction could reach up to 70% in residential buildings. Electricity consumption and peak demand reduction in commercial buildings was not high. Reducing lighting power density in residential buildings, using higher glazing efficiency in small offices and using thermal mass in big offices were found to be able to reduce more peak load when electricity output from PV systems were incorporated in the buildings compared with other measures. Energy efficient design measures suitable for different purposes in each building type have been identified. Building owners and electricity utilities can use this information to select the best energy efficient design measures that fit their objectives.
