There has been a plea for sustainable use of resources since the twentieth century. Buildings are known to consume forty percent of the world’s resources. Resources such as gas, oil, coal and electrical energy used in heating, cooling and ventilation of buildings are limited, as well as causing air pollution and climate change. For this reason, the energy resources used in the buildings should be used effectively, considering environmental concerns. The aim of this study is to describe the shift in efficient use of energy in buildings using a biomimetic approach in thermoregulative building envelope strategies that support internal thermal comfort. In this study, passive systems integrated into buildings which use solar energy, one of the renewable energy sources for heating, cooling and ventilation purposes have been examined. The methods followed by nature in using solar energy are discussed with the biomimetic approach and suggestions have been made to support the increase of energy efficiency by applying the obtained teachings to passive building envelopes. Keywords: biomimetics; building envelope; kinetic building envelope; passive strategies; Thermal comfort

The present study provides comprehensive analyses of a newly constructed passive energy-efficient building located in Harbin, China, which is a prime example of how to design a passive building that withstands the severe cold climate in northeast Asia. Conduction transfer functions of heat flux equilibrium are employed to simulate energy consumption characteristics of the paradigm passive building. The climatic conditions in severe cold region are analyzed, and the energy-saving designs in the studied engineering cases are summarized for their practical applications. Building physical models are established to perform numerical simulation analyses on the passive building paradigm in northeast Asian frigid zone. The dominant technical parameters of envelope structure affecting energy consumption in severe cold region, including thermal insulation thickness and heat transfer coefficient of building envelope, as well as window-to-wall ratio for each building facade, are taken into consideration as simulation variables to calculate cooling load, heating load, electricity consumption, and CO2 emission, which account for energy efficiency of passive buildings. The simulation results demonstrate the high energy-saving potential of the proposed passive building design and render the optimal energy-efficient parameters suitable for severe cold regions, which can reduce energy consumption and CO2 emission while ensuring comfort for occupants. The present study provides a theoretical reference for envelope structures of passive buildings in severe cold regions, which is of great significance to the development of green buildings and relevant policies.

The engineering of building envelope aims is to achieve building energy efficiency which uses shading device to increase the shaded area. Also, to reduce heat gain by the building from solar radiation, this will reduce the energy load on the building. This paper aim to focuses on the deepening of technology of building envelope elements, and how the building envelope can control the thermal comfort as part of the indoor environment in a building that carries sustainability architecture. In conclusion, finally, reveal that the principles of passive design on building envelope have a great influence on the comfort level in the building. It is not possible to create a design that meets the thermal comfort requirements by emphasizing the design of building envelopes. The goal to be achieved in sustainable design is to minimize the use of the current design that takes much energy (almost14% world energy consumption) to address the issue of energy crisis lately.

Several attempts have been made in tropical countries to conduct green mock-up research on which parameters can better withstand the heat and humidity: Walls, windows, roofs, and even shadings have been tested in mainly so-called contrived experiments. The challenge of a tropical "holistic" Passive building is to bring ALL those relevant parameters into play in different seasonal and weather situations whilst expelling the interference of the hot outside air. In principle, this is happening anyway for most commercial buildings and Passive Houses in all other hemispheres alike, but it is not common for tropical residential building strategies. The author refers back to a database of 250 days from a suburban area in Malaysia. Data out of 4 typically hot months in the year 2017 in detail with 3 adjacent real mini-residential Passive and 1 "red" House(s) with the same positioning for ambient temperature and the most vulnerable part of the building envelope which is the window were cross-examined. The well insulated, basically almost airtight and optimum shaded building with ventilation performed cooler in almost all cases during the rainy season and the increasing number of transition periods. Without aircon and due to the lack of a moisture barrier it remained humid, but with no harm for occupants and the building envelope. The Passive holistic design will work best i.e. energy efficiently in a combination of a) nighttime active usage of green cooling (i.e. cross ventilation or water-based cooling ceilings). During b) daytime, among other related modules looked in, cooling is based upon passive envelope features PLUS shading. For various reasons, compared to buildings in the colder hemisphere (such as tropical thin building envelope and no triple glazing required), the payback of the Tropical Mass Residential Passive House comparing OPEX and CAPEX is reasonable with 5-6 years.

Passive buildings can achieve energy saving goals through their own spatial form, envelope, building materials and structural design. However, at present, there are many problems in the development of passive buildings in China, such as inadequate foundation, unreasonable passive design, which make the development of passive buildings have many obstacles, not conducive to the promotion of the construction industry. Therefore, this paper analyzes the obstacle factors of passive buildings and puts forward reasonable solutions for reference.

Abstract Faced with the problems of existing buildings in cold areas, such as poor insulation performance of envelope, high heating cost and substandard indoor temperature in winter, based on DeST-h energy consumption simulation software, taking typical single buildings in Zhangjiakou as an example, several factors affecting building energy consumption were analyzed. The building energy consumption values in heating season under 9 envelope reconstruction conditions were obtained by orthogonal experiments, and 4 different energy supply systems were designed for buildings under 9 envelope reconstruction conditions. The “with or without comparison method” is used to evaluate the building energy efficiency of 40 working conditions after the superposition of the initial state and passive transformation of existing buildings in the whole life cycle. The evaluation results show that the external wall insulation and extrusion plate thickness is 80 mm, the roof insulation and extrusion plate thickness is 100 mm, and the glass type is ordinary hollow glass ( 6 + 9 + 6 ). The air source heat pump assisted energy supply effect is the best, but the overall economy will change with the initial investment, local electricity price policy and building scale.

The increasing need for eco-friendly green building and creative passive design technology in response to climatic change and global warming issues will continue. However, the need to preserve and sustain the natural environment is also crucial. A building envelope plays a pivotal role in areas where the greatest heat and energy loss often occur. Investment for the passive design aspect of building envelopes is essential to address CO 2 emission. This research aims to explore the suitability of using integral-monolithic structural insulation fibre-reinforced lightweight aggregate concrete (LWAC) without additional insulation as a building envelope material in a high-rise residential building in the different climatic zones of the world. Polypropylene and steel fibres in different dosages were used in a structural grade expanded clay lightweight aggregate concrete. Physical and thermal properties of fibre reinforced structural LWAC, normal weight concrete (NWC) and bricks were measured in the lab. The Autodesk@Revit-GBS simulation program was implemented to simulate the energy consumption of a 29-storey residential building with shear wall structural system using the proposed fibre-reinforced LWAC materials. Results showed that energy savings between 3.2% and 14.8% were incurred in buildings using the fibre-reinforced LWAC across various climatic regions as compared with traditional NWC and sand-cement brick and clay brick walls. In conclusion, fibre-reinforced LWAC in hot-humid tropical and temperate Mediterranean climates meet the certified Green Building Index (GBI) requirements of less than 150 kW∙h∙m−2. However, in extreme climatic conditions of sub-arctic and hot semi-arid desert climates, a thicker wall or additional insulation is required to meet the certified green building requirements. Hence, the energy-saving measure is influenced largely by the use of fibre-reinforced LWAC as a building envelope material rather than because of building orientation.

Latent heat thermal energy storage systems incorporate phase change materials (PCMs) as storage materials. The high energy density of PCMs, their ability to store at nearly constant temperature, and the diversity of available materials make latent heat storage systems particularly competitive technologies for reducing energy consumption in buildings. This work reviews recent experimental and numerical studies on the integration of PCMs in building envelopes for passive energy storage. The results of the different studies show that the use of PCMs can reduce the peak temperature and smooth the thermal load. The integration of PCMs can be done on the entire building envelope (walls, roofs, windows). Despite many advances, some aspects remain to be studied, notably the long-term stability of buildings incorporating PCMs, the issues of moisture and mass transfer, and the consideration of the actual use of the building. Based on this review, we have identified possible contributions to improve the efficiency of passive systems incorporating PCMs. Thus, fatty acids and their eutectic mixtures, combined with natural insulators, such as vegetable fibers, were chosen to make shape-stabilized PCMs composites. These composites can be integrated in buildings as a passive thermal energy storage material.

The aim of this study was to investigate the effects of windows and building
envelope materials on the thermal performance of residential buildings, for
the climatic conditions of Ankara.
The effects of the thermal mass of the building envelope, together with the
effects of glazing type and shading conditions of south-facing windows on
thermal performance were investigated using two computer-based thermal
analysis programs called: ECOTECT 5.0 and ENERGY-10. The
hypothetical building model used for computer simulations was based on the
sample residential building defined in the Turkish Standards on the
Regulations for Building Insulation, TSE 825, as prepared by the Türk Standartlari Enstitü
sü
(TSE, Turkish Standards Institute). Simulation studies were first conducted with ECOTECT 5.0, but since the results did not conform to earlier researches and, since this discrepancy could not be explained even by the support forum prepared by the authors of this software, it was decided to continue the simulations with ENERGY-10, which proved to be more consistent. The results of 240 program runs of ENERGY- 10 were explained through graphical and statistical analysis on the basis of annual heating, cooling, and total energy needs of the building model. The study showed that building envelope materials having high thermal storage capacities together with high-performance glazing, in terms of increased thermal resistance, provided significant energy savings, which could be augmented by increasing the size of south-facing windows. The study also revealed that shading devices in the form of fixed overhangs applied to a south-facing window of any size did not provide substantial reductions in the energy demands of residential buildings, when annual total energy demands were considered for the climatic conditions of Ankara.

Greenhouse gases emissions and energy consumption in buildings were constantly increasing the last 4 decades, representing 25% of total emissions and 32% of global final energy consumption in 2010. These emissions are expected to double or even triple by 2050 according to international institutions projections. Therefore, the reduction of greenhouse gases emissions and energy consumption becomes a necessity to encompass pollution and climate change mitigation. One of the objectives of this PhD thesis is to analyse the trends of the energy consumption of European residential buildings. The main action recommended by the International Energy Agency to reduce significantly the energy consumption in buildings is to improve their envelopes with appropriate materials and construction systems. For this reason, this PhD thesis is focused on materials with thermal properties improved using phase change materials (PCM) for latent thermal energy storage in passive systems and/or sustainable materials to be placed in building envelopes.

Les économies d'énergie et la réduction des émissions des gaz à effet de serre dans le secteur du bâtiments ainsi que le maintien d’un confort hygrométrique prennent une importance majeur ces dernières décennies. L'utilisation de matériaux à changement de phase (MCP) ou de matériaux hygroscopiques d'origine végétale pour l'enveloppe des bâtiments est une solution prometteuse. Les MCP conduit à améliorer le confort thermique intérieur et à réduire la consommation d'énergie, tandis que les matériaux hygroscopiques biosourcés sont des matériaux respectueux de l'environnement et permettent la régulation de l'humidité intérieure et assure une isolation thermique optimale. Cependant, seules quelques études ont exploré l'application l’intégration de ces deux types de matériaux et analysé de manière exhaustive les performances énergétiques et hygrothermiques. Cette thèse propose une solution d'enveloppe passive qui intègre le PCM et le béton de chanvre biosourcé pour améliorer simultanément les performances énergétiques, et hygrothermiques du bâtiment. Les principaux objectifs de cette étude sont d'examiner la faisabilité des enveloppes intégrées, d'étudier de manière exhaustive les performances hygrothermiques et énergétiques ainsi que les avantages et les inconvénients de différentes configurations avec le PCM placé à différents endroits du béton de chanvre.Tout d'abord, des expériences ont été menées en comparant les performances hygrothermiques d'une enveloppe de référence (béton de chanvre uniquement) et de trois enveloppes intégrées avec du MCP placé à différents endroits dans deux conditions limites typiques. Les résultats ont montré la faisabilité des enveloppes intégrées. La présence de PCM a augmenté les inerties thermique et hygrique de l'enveloppe. Par conséquent, le déphasage a été augmenté et l'amplitude de la température et de l'humidité relative a été réduite. Les différentes configurations présentaient des avantages et des inconvénients différents. La configuration dans laquelle le MCP est placé au milieu du béton de chanvre est intéressante car elle présente une faible fluctuation et un dephasage interessant à la fois pour les variations de la température et de l'humidité relative, et conduit ainsi à de grandes économies d'énergie.Ensuite, le modèle physique i, de transfert de la chaleur et de l’humidité, à l’échelle de l'enveloppe a été développé. Ce modèle intègre la dépendance de la température et de la caractéristique hygroscopique du béton de chanvre. La précision du modèle a été validée par comparaison avec les données expérimentales. Sur la base du modèle validé, les simulations ont été effectuées dans un climat méditerranéen afin d'étudier de manière exhaustive les performances hygrothermiques et énergétiques de l'enveloppe intégrée. Les résultats ont mis en évidence le rôle indispensable du transfert d'humidité dans la détermination de la charge hugrothermique, ainsi que l'effet précieux de l'enveloppe sur l'amélioration des performances énergétiques et hygrothermiques. En outre, l'enveloppe intégrée avec le PCM proche de (mais pas en contact avec) l'intérieur a montré un grand potentiel pour économiser de l'énergie et s'adapter aux variations d'humidité du climat tout en garantissant l'équilibre de l'humidité dans le béton de chanvre. Enfin, l'analyse paramétrique a été réalisée du point de vue des propriétés du MCP (épaisseur, chaleur latente et plage de transition de phase), et le risque d'application (condensation et développement de moisissures) a été évalué. Les résultats de l'analyse paramétrique ont montré que les performances de l'enveloppe pouvaient être améliorées en augmentant l'épaisseur et la chaleur latente de MCP et en identifiant la plage de transition de phase appropriée du MCP. Les résultats de l'évaluation des risques ont confirmé que l'enveloppe ne présentait aucun risque de condensation et de développement de moisissuresWith the development of society, the demand for energy saving and carbon emission reduction in buildings as well as the indoor thermal and humidity environment comfort is gradually increasing. Using Phase change materials (PCMs) or bio-based hygroscopic materials as building envelopes are promising solutions. PCMs can improve indoor thermal comfort and reduce energy consumption, while bio-based hygroscopic materials are environment-friendly materials that enable indoor humidity regulation and thermal insulation. However, only a few studies have explored the integrated application of the two types of materials and comprehensively analyzed the energy and hygrothermal performance. This dissertation proposed a passive envelope solution that integrates PCM and bio-based hemp concrete (HC) to simultaneously improve the energy, thermal, and hygric performances of buildings. The main objectives of this study are to investigate the feasibility of the integrated envelopes, to comprehensively study the hygrothermal and energy performance as well as the advantages and disadvantages of different configurations with PCM placed in different locations of the HC, and to conduct the parametric analysis and evaluate the application risks of the integrated envelope.First, experiments were conducted by comparing the hygrothermal performance of a reference envelope (HC only) and three integrated envelopes with PCM placed in different locations under two typical boundary conditions. The results demonstrated the feasibility of the integrated envelopes. The presence of PCM increased the thermal and hygric inertia of the envelope. As a result, the time delay was increased and the temperature/relative humidity amplitude was decreased. Different configurations had different advantages and disadvantages. The configurations with PCM placed in the middle of the HC was worth noting as it had small temperature/relative humidity fluctuation, long temperature time delay, and large energy savings.Then, the mathematical model of the integrated envelope that couples heat and moisture transfer and considers the temperature dependence of HC’s hygroscopic characteristic was developed. The accuracy of the model was validated by comparison with the experimental data. Based on the validated model, the simulations were performed in a Mediterranean climate to comprehensively investigate the hygrothermal and energy performance of the integrated envelope. The results highlighted the indispensable role moisture transfer plays in determining the indoor hygric environment and heat load, as well as the valuable effect of the integrated envelope on improving both energy and hygrothermal performance. Besides, the integrated envelope with PCM close to (but not in contact with) the interior showed great potential for saving energy and adapting to climate humidity variation while guaranteeing moisture equilibrium within the HC.Finally, the parametric analysis was performed from the perspective of PCM properties (thickness, latent heat, and phase transition range), and the application (condensation and mold growth) risk was evaluated. The results of the parametric analysis illustrated that the performance of the integrated envelope could be improved by increasing the thickness and latent heat and identifying the appropriate phase transition range of the PCM. The risk evaluation results confirmed that the integrated envelope was free from the risk of condensation and mold growth

It is desirable for a glazed façade to have a variable performance to moderate a building’s energy-balance from seasonal variations in solar gains (Davies, 1981). A novel actuator mechanism is developed that self-regulates a façade by physically reconfiguring its movable elements into different environmental control functions. Its practical feasibility is explored with a proprietary thermal actuator that exploits the expansion of wax during melting from its absorption of heat energy. This provides a means to operate a mechanism solely by its response to passive energy exchanges given prevailing weather conditions. An advance is needed for thermal actuators to respond differently to the seasonal intensity of sunlight. A means to overcome this obstacle is explored through the possibility of linking multiple heat-motors into thermal comparators. A methodology is adopted to iteratively develop virtual models of mechanisms and energy-flows, complemented by practical machines for testing in controlled climate-chambers and observation on uncontrolled sites. The possibility of differentiating the energy-balance between actuators by amplifying seasonal differences in the daily intensity of sunlight under clear-skies is investigated using hot-boxes. Simulations predict the possibility of a well-differentiated annual repertoire of responses that reconfigures façade elements for daylight access, solar shading and night-time insulation. Practical thermal actuators in hot-boxes arranged with differentiated exposure to sunlight were observed through a cycle of seasons. The results demonstrate the feasibility of a seasonal difference in actuator responses from daily cycles of accumulated and rejected heat-energy. The development of a passive means to seasonally marshal the state of wax in response to sunlight and use linked thermal actuators to mechanically express it has shifted the conceptual ground away from environmental control that is abstracted. Architects can move towards the design of dynamic building façades that can literally reconfigure in and of itself by virtue of the embodied state of its material components.

Passive radiative cooling has been extensively studied as a means to cool the exterior surfaces of buildings and reduce space cooling loads. This phenomenon is caused by thermal radiation that is continuously emitted from surfaces on Earth, and transmitted through the atmosphere to outer space (at approximately 3-4 Kelvin temperature scale). To gain a deeper understanding of how terrestrial objects can access this extraterrestrial cold reservoir, I use a theoretical framework derived from classical radiative heat transfer to investigate the radiative properties of surfaces and the atmosphere over a spectrum of wavelengths. In this dissertation, I demonstrate the theoretical cooling potential that can be achieved by surfaces with idealized radiative properties under various atmospheric conditions. While several researchers have optimized the optical properties of their surfaces to emit strongly in wavelength bands corresponding to high atmospheric transparency, I show that a high degree of spectral tailoring is only benefcial when humidity in the atmosphere is low or when a surface can minimize its absorption of solar radiation. Additionally, I prescribe appropriate sets of surface radiative properties that are required to achieve cooling under various solar and atmospheric loads.
An evaluation of passive strategies on building envelopes would be incomplete without considering green facades. To that end, I propose a theoretical model to calculate the heat flux reduction offered by green facades. Unlike previously reported works that use the Pennman-Monteith approach to calculate evapotranspiration in a leaf canopy, my model takes a simpler approach in calculating the sensible and latent heat loss from a layer of leaves while preserving prediction accuracy. By extending the theoretical models for passive radiative cooling and green facades to building envelopes, my work provides insights into the appropriate passive strategy suitable for a particular climate. In dry conditions, surface coatings with optically-tuned radiative properties can perform better than green facades by maximizing their thermal emission through the atmosphere. However, the additional evaporative cooling benefits, insulation and aesthetic value offered by green facades may make them more favorable in cooler and more humid climates. Since the cooling performance of all passive strategies is strongly correlated to the local climate, my work indicates that variations in ambient air temperature, solar radiation and humidity must be considered when choosing an appropriate strategy for a building envelope.

Taiwan is a sub-tropical country with hot and humid climate. During the summer, a large amount of air condition facilities and mechanical ventilation energy are used to improve indoor comfort of buildings and bioenvironmental facilities in bioproduction. Lots of efforts are devoted for the purposes of improving indoor thermal comfort, reduce heat gains from buildings envelope and to decrease cooling energy. The present research presents passive ventilation design by adopting double envelope construction with air flow gaps. The influence of ventilation rates and construction models is studied experimentally and numerically. The study is to evaluate the insulation performance and energy consumption of double envelope construction with effective air gap thermal resistance, thermal conductance and solar radiation cooling loads. Fifty different kinds of envelope elements are tested under different kinds of ventilation rate and construction models in this experiment. The purpose of the study is to analyze the temperature distribution, air velocity, air change rate, heat gains, thermal resistance, thermal conductance and solar radiation cooling loads. Using numerical steady model to calculate the surface, average and outlet temperature of air gap, and to acquire the effective air gap thermal resistance. The results of this research are summarized as follows: Without any mechanical ventilation system, experimental results shows that the natural ventilation of air flow gap can reduce about 76% solar radiation cooling loads and 74.3% of heat gains. Comparision between simulated and experimental results showed a good record, therefore the numerical model is valid. At a fairly conservative estimate, the solar radiation cooling loads can reduce up to 67.5% than those eight types envelope widely used nowaday. The thermal conductance is changed to one third of the original type envelope. The research shows that the double envelope construction with air flow gap is a effective way to reduce the solar radiation cooling loads of buildings and bioenvironmental facilities.

AbstractBuilding envelopes represent the interface between indoor and outdoor environmental factors. In recent years, attention to climate adaptive building envelopes has increased. However, some types of adaptive envelopes don’t always offer low-tech solutions, but require energy for their activation and high operating and maintenance costs. Nature has always proposed a large database of adaptation strategies that are often complex, multi-functional, and responsive. Transferring the functional principles of natural organisms and their associated adaptive modalities to technologies is the challenge of the biomimetic discipline (from Greek bios, life, and mimesis, imitation) applied to the field of architecture. In this article, various examples of biomimetic architecture that illustrate the relationships between biology, architecture, and technology, were considered. Various analyses of the operating principles of natural organisms are carried out, particularly with regard to self-adapting materials, in order to transfer them to the building envelope, and to propose technological solutions capable of passively adapting to external climatic conditions. Among all natural organisms, plants are prefereble to animals because, like buildings, they remain stationary in a specific location. Despite this, plants have developed different adaptation mechanisms to survive in certain environments. Buildings with biomimetic adaptive envelopes, characterized by passive and low-tech solutions inspired by plants, help limit energy consumption, and improve not only the indoor microclimate but also the outdoor environment. In line with the ecological transition, this work highlights the importance of biomimetic as a strategy to orient the new paradigms of built space design towards innovative and sustainable models of low-tech solutions.

AbstractFollowing architectural practice’s widespread adoption of 3D modelling software, the digital design of free-form surfaces has enabled more heterogeneously organized architectural assemblies. However, fabricating envelope components with double-curved surface geometry have remained a challenge, involving significant machine time and material waste, and great expense to produce. This proof-of-concept project proposes a rapid, low-cost, and minimal-waste approach to forming double curved ceramic components through a novel approach to Ceramic Incremental Forming (CIF), using a 6-axis industrial robot, a passive flexible mold, and a custom ball-rolling tool. The approach is comparable to Single Point Incremental Forming (SPIF) that is used for forming complex shapes with metal sheets. This method promises to achieve high-quality, ceramic building envelope components, while eliminating the need to build proprietary molds for each shape and reducing the waste in the forming process. Compared with other architectural mold-less forming methods such as clay 3D printing, the approach is more time and material efficient, while being able to achieve similar levels of complexity. Thus, CIF may offer potential for further development and industrial applications.

AbstractOver the last few years, the concept of a more sustainable/eco-responsive skin featured as alternative envelopes for buildings (sometimes termed “Living Architecture”), designed to achieve low energy consumption, cost efficiency, and user comfort. Until today, architects in the UAE tend to design projects with double skin façades more than providing living architecture façade to achieve energy efficiency and sustainability in an extremely hot climate. Since the 1990s buildings in Gulf cities were dressed in cladding, which ignores the importance of building orientation, passive design ideas, and implementation.Purpose – This paper examines the concept of living architecture in the context of the UAE and proposes a framework to retrofit existing unsustainable designs with more eco-responsive ones.Methodology – Energy analysis will be applied to the façade of Baynunah Hilton Tower in Abu Dhabi before and after providing a living architectural façade technique in order to test the energy efficiency of the facade between the two scenarios. The analysis will be applied using FormIt software.Findings – The new proposed façade design “Light-weight Aluminium with Arabesque pattern” have affected positively the energy performance of the building. The energy consumption has been reduced by almost 38% after applying the retrofitting design to the façade.Implications – Façade retrofit is important as it helps in providing sustainable design solutions for the building’s facade that plays an important role in achieving energy efficiency and saving the environment.Originality/value – All the scenarios and simulations were done by the authors using FormIt software.

The reduction of anthropogenic green house gas emissions through increased building energy efficiency is a global effort, which is a responsibility of both developed and developing nations. The Passive House concept is a building design methodology that advocates for a systematic optimization and integration of the building envelope and internal loads in order to achieve a passive yet comfortable performance. Multiple passive houses have been built and monitored in Europe and the United States. The present paper attempts to determine what design features are required for tropical residential buildings to meet the Passive House Standard. This study was conducted in El Salvador, which experiences a warm and humid climate throughout the year. For economic and cultural reasons, few residential buildings in the country have air conditioning systems. However, the vast majority of residential buildings have not been designed using passive principles, causing great occupant discomfort and increasing energy consumption for cooling. Both the Passive House Planning Package (PHPP) software and EnergyPlus were used in order to determine the design parameters that would yield a passive house for this climate. In addition, the paper discusses the technical and economic feasibility of modifying a typical house to meet the standard. The potential benefits related to occupant comfort and energy cost savings are also discussed.

Heating and cooling load calculations are critical to size Heating, Ventilation and Air conditioning (HVAC) systems and determine energy use of their operations. The ASHRAE (2009) model, which is most commonly used for heating load calculations, adopts a simplified approach by considering only steady-state instantaneous conductive heat transfer and ignoring internal heat gains and thermal storage effects. Those assumptions evaluate the worst case conditions which can reasonably occur at nights when the outdoor air temperature is lowest and with no inputs from solar, occupants, lights, or any electronic devices. However, due to thermal storage effect, heat generated in daytime can be still stored in buildings. Such ignorance leads to significantly over-sized heating system, high initial cost and a higher cost of energy uses. On the other hand, by considering passive thermal storage of buildings and allowing space air to drift to reasonably lower values, buildings need to be warmed up in the morning before being occupied. The worst case conditions might happen in the morning warm-up period, when heating is needed. This study therefore examines the thermal response of different constructions (heavy, medium, and light) of the building envelope and investigates the effect of their passive thermal storage on the size of the heating system. Results show tremendous opportunities for downsizing of the heating system while still maintaining thermal comfort requirements. As such, this paper is a fundamental study of building thermal characteristics in order to investigate the potentials of establishing a new heating device design standard.

Active Building Envelope (ABE) systems represent a new thermal control technology that actively uses solar energy to compensate for passive heat losses or gains in building envelopes or other enclosures. This paper introduces the first steps in exposing the community to this new technology, and explores an optimization based design strategy for its feasible application. The overall system is discussed, while this paper also gives particular focus to the design of a key constituent component. Namely, the collection of thermoelectric heat pumps; or, the TE unit. The latter becomes an integral part of the generic enclosure, and is a collection of thermoelectric coolers, or heaters. As a critical component of the optimization based design strategy, select computationally inexpensive approximate analytical models of generic TE coolers/heaters (TE Cooler) are developed. The optimization technique is implemented to evaluate different design configurations of the TE unit. The preliminary results indicate that the total input power required to operate the TE unit decreases as the distribution density of the TE coolers increases. In addition, the thermal resistance of the heat sink (attached to the TE cooler) plays a key role in determining the number of TE coolers required. These preliminary findings may have practical implications regarding the implementation of the ABE system.

The paper explores the possibilities of increasing the comfort of residents by applying a greenhouse as an element in the organization of houses' space. The topic of the paper is the organization of residential buildings based on the space within a space concept, i.e. the layered structure of architectural composition, with the aim of improving the microclimate of the building and using passive energy sources. The inspiration for the research comes from examples of houses in northern Europe, where the glass envelope is used as an membrane around the building, influencing the maximum utilization of insulation, preventing heat loss, and creating additional useful space inside the house. The research was conducted through the analysis of examples from practice, based on which characteristics, benefits, and drawbacks of such a concept were synthesized, resulting in the development of variant schemes and models. The aim of the paper is to promote atypical simple architectural interventions that contribute to energy saving in buildings, passive design, and increased comfort.

The built environment is responsible for nearly 40% of global energy use, significantly contributing to carbon emissions. Targeting a carbon-negative future would require a rethinking of the way we heat and cool buildings, distancing ourselves from the predominant model for the building envelope as a boundary that excludes the weather and instead adopting alternatives that transform the building envelope to a mediator that actively regulates heat exchange. In this paper, we explore the potential for a building boundary that actively heats and cools a building by forming dynamic relationships with surroundings. Most decarbonizing efforts today focus on realizing net-zero operational carbon either via the production and distribution of renewable energy or via passive house strategies that target the reduction of the active energy demand. We propose a third alternative. Instead of an endothermic model for heating and cooling in which energy is brought in the interior, transformed by a mechanical system and then distributed, we propose an ectothermic envelope system that dynamically forms a relationship with its environment, by choosing to absorb or release heat directly from or to the environment. From a design perspective, we will show a modular building energy system, comprised of a double hydronic heating and cooling layer. In essence, we are developing for a building, the equivalent to a vascular system that can move liquids at different locations to thermo-regulate. We will show how this vascular system can use ambient heat as heating and cooling sources for a building. From a more technical perspective, since all simulation tools available today assume an endothermic approach, we will show an alternative using Modelica and co-simulation for simulating an ectothermic approach. We are developing a weather chamber, which can generate an artificial version of the weather from data to test how our system would dynamically respond.
