Abstract:

Literature review shows that, to date, no local based method has been developed for evaluation of optimal wall constructions in a hot and humid climate from architects’ point of view. Hence, this study aims at developing a multi factor optimization model (MFOM) for comparative selection of opaque wall construction in a hot and humid climate based on four main evaluation criterion namely energy efficiency, thermal comfort, moisture control, and cost efficiency. In order to indicate the application of the MFOM, a case study methodology was employed in Kish Island, Iran, which is characterized by a hot and humid climate. Both qualitative and quantitative research methods were employed in the research process including literature and field survey, computer simulation, thermal, moisture and economic analysis finalized with a simple multi attribute rating technique (SMART) grading the outputs for final assessment. According to the results, it can be deducted that the application of the MFOM has the potential to save cost and energy, improve the thermal quality of the indoor environment while predicting the possible construction hazards posed by condensation in hot and humid climates.

Abstract:

Pure polystyrene (PS) was subjected to natural weathering in Qionghai (QH) and Ruoqiang (RQ) of China, representing hot and humid climate and xerothermic climate respectively. The degradation profile of pure PS was studied by Fourier Transform Infrared (FTIR) Spectroscopy, Differential Scanning Calorimetry (DSC), Scanning Electron Microscope (SEM), X-ray Photoelectron Spectroscopy (XPS) and Spectrophotometer. Artificial accelerated weathering tests protocol A and B were carried out to simulate hot and humid climate and xerothermic climate respectively. Results show that pure PS degrade slowly at the initial stage and then become faster. Color shift could be an appropriate indicator for evaluating simulated effect of artificial accelerated weathering and protocol A simulate hot and humid climate perfectly while protocol B turns out weak for xerothermic climate.

Abstract:

The issue of Climate Change has raised so much attention for decades, specifically in recent years. Modern trends in urban architecture which tried to create living machines similar to each other in any context, have now been proven to be insufficient and unless we decide to respect nature and make our buildings cooperate with their contexts as soon as possible we cannot address further threads regarding our future life. If we take a look at traditional architecture existing in old towns and rural area, we can see how people managed to bond a new construction with its surroundings. In this article we study different architectural patterns which exists in old architectures of towns and villages in Iran; the country which can be a good case study due to its rich diversity of nature, climate zones and architectural background. In Iran we have a range of climate of cities from hot and dry to humid and very cold ones. So, depending on the city climate, water supplies and energy sufficiency people tried to create best residential buildings. Here we try to check out some examples.

Abstract:

One of the fundamental determinants of buildings is the protection of the people who live and work within them from a harsh climate, but a lot of buildings in Nigeria are no longer providing the required comfort needed. The gas emissions through the use of mechanical equipment and lack of energy efficiency in buildings are the major causes of climate change. The way architecture responds to climate change is important. Thus, this research attempted, by using the new bioclimatic chart, to prepare the new climate classification of Nigeria. The research was aimed at establishing a bioclimatically based approach for architecture in Nigeria. By retrieving the climatic data from thirty-six Nigerian meteorological stations about characteristics of each region, bioclimatic analysis was achieved. According to the bioclimatic analysis of this research, Nigeria can be divided into five different climatic regions, such as hot-dry, hot-humid, temperate-dry, temperate-humid, and temperate-dry with a cool climate. We aimed to prove that the climate classification gives the proper answer, dependent upon the vernacular architecture analyzed on Nigeria.

Abstract:

Iranian traditional architecture has always been a good example of climatic design and represents the techniques which our ancestors have found to improve their living conditions. By paying attention on Iranian traditional architecture we could confirm that its rules suit buildings in best way in sustainability and in correspondence to the local cultural, topographical and climatic conditions which have the least adverse effect on environment. One of the most significant features of traditional Iranian architecture is the special architectural specification in various climates, which makes each region distinct from the others. Investigations of different Iranian regions indicate that in past, different techniques and methods for controlling and making air movement in interior space of the building were common. Harsh climate of these areas in Iran forced people to build their houses with some strategies based on efficient energy consumption. In this paper different solutions of sustainability will be discussed in three different climate regions of Iran: hot-arid region, hot-humid region and humid-rainy regions (Southern Shores of Caspian Sea Region)

Abstract:

ABSTRACT Broccoli has great economic, social, and nutritional importance. Genetic improvements through breeding programs for this species made available cultivars with satisfactory production in hot and humid climates. Two experiments were conducted to evaluate the inflorescence production of broccoli cultivars (Ramoso and Cabeça groups) in the hot and humid climate of Central Amazonia. In experiment 1, Ramoso group cultivars were evaluated (Verão Ramoso Piracicaba, Ramoso Santana, Piracicaba, Piracicaba Precoce, Ramirez F1, Hanabi, Piracicaba Precoce Verão, and Hanapon ). In experiment 2, Cabeça group cultivars were evaluated (Green Storm, Strong, TPX-00925, Salinas F1, Bibou, Domador, Burney, and BRO 68 ). A randomized block experimental design was used, with eight treatments consisted of cultivars, and four replications for each experiment. Quantitative variables were evaluated, including inflorescence fresh and dry weights; and the qualitative variables evaluated showed the occurrence of undesirable characteristics in the inflorescences. Significant differences were found within the Ramoso group cultivars and within the Cabeça group cultivars evaluated. The broccoli cultivars that showed the best inflorescence production in the humid, hot climate of Central Amazonia were Verão Ramoso Piracicaba, Piracicaba Precoce Verão, Ramoso Santana, and Piracicaba Precoce of the Ramoso group; and Green Storm and Burney of the Cabeça group.

Abstract:

ABSTRACT Climate is the set of average atmospheric conditions that characterizes a region. It directly influences the majority of human activities, especially agriculture. Climate classification systems (CCSs) are important tools in the study of agriculture, enabling knowledge of the climatic characteristics of a region. Thus, we aimed to perform the climatic characterization of the State of Paraná using the methods proposed by Köppen and Geiger (1928), modified by Trewartha (1954) (KT), Thornthwaite (1948) (TH) and Camargo (1991) and modified by Maluf (2000) (CM), using data from the European Center for Medium-Range Weather Forecast (ECMWF) model. The results of spatial interpolation (virtual stations) were performed using the Kriging method in spherical shape with one neighbour and resolution of 0.25°. The CCSs displayed the ability to separate the warm and dry from cold and wet regions. The most predominant climates were Cfa (temperate humid with hot summers), C1rA'a' (sub-humid with little water deficiency, megathermal) and ST-UMi (humid subtropical with dry winter), according to KT, TH and CM, respectively. CM is an intermediate CCS between KT and TH.

Abstract:

In tropical climates, the solar radiation absorption of glazed windows results in overheated indoor environments and increased cooling energy loads during daytime. Meanwhile, situations differ during nighttime. The present study focuses on the effects of glazing type on the indoor temperature in high-rise residential buildings in the hot and humid climate of Malaysia. The primary objective of this study is to assess the effects of six glazing types on the indoor air temperature of the base case room oriented toward the southwest with a Window Wall Ratio WWR of 45% under both ventilated and unventilated conditions. The effects during daytime and nighttime are investigated separately. A computerized simulation tool (Virtual Environment by Integrated Environmental Solutions) is used to conduct the investigation. Penang is selected as the empirical background location of a hot and humid climate. The study found that reflective double glazing exhibits lower indoor air temperature throughout the day regardless of the ventilation condition, with an optimum improvement of up to 107% and 14% in unventilated and ventilated rooms, respectively, compared with single clear glazing. The study recommends the use of reflective single or double glass in regions with a hot and humid climate similar to that of Malaysia.

Abstract:

Indonesia is located in a hot, humid climate, and one of the abundant and indigenous natural resources in Indonesia is bamboo plants. People in everyday life widely use bamboo. However, the community has not been adequately educated about bamboo, especially in terms of (1) processing, (2) preserving, and (3) maintaining bamboo. These three things have essential roles in supporting the bamboo's durability since bamboo is susceptible to destructive organisms. In this study, the durability of bamboo was observed, interviewed, and analyzed to examine the most optimal bamboo preservation method for construction use in a hot, humid climate. The type of bamboo and the characteristics of bamboo were assessed: both by chemical and traditional methods of preservation. This study found that in terms of durability, the traditional preservation method results in stronger durable bamboos. The traditional methods are considered to be more optimal for bamboo building construction in a hot, humid climate.

Abstract:

In this paper, the thermal and ventilation potential of a geothermal Earth-to-Air Heat exchanger (EAHE) is studied for six weather in Mexico. The cities for the study and their climate were Villahermosa (hot-humid), Merida (hot-sub humid), Monterrey (dry), Juarez City (very dry), Zacualtipan-Hidalgo (warm-humid) and Mexico City (warm-sub-humid). The thermal behavior of the EAHE was modeled numerically for the corresponding warmest and coldest days of the year for each city and three values of Reynolds number. The 24 hrs simulations were carried out with an in-house code using data every 10 minutes. To get the results, 5,184 computational runs were necessary. The results showed that the EAHE has poor ventilation potential for climates with high levels of humidity such as Villahermosa, while for cities with low levels of humidity such as Chihuahua, the ventilation potential increases significantly, the rest of the cities fall in between. As for its application in Mexico, the results show that the EAHE is highly recommended for dry climates such as at the north of the country and not recommended for humid climates such as at the south and south-east of the country.

Abstract:

Geothermal heat pump (GHP) systems are more concentrated to moderate climate regions, although the potential for GHP systems in hot and humid climates is possible as past research efforts have demonstrated this using simulations and commercial case examples. This research investigates the use of residential GHP systems for the hot and humid climate found in southern Louisiana. The authors collected field performance information, including initial system cost, and electricity consumption and costs from two residential case studies in which each case included one home with a conventional heating and cooling system and one home with a GHP system. Using a comparative analysis and analysis of variance, results illustrate that initial cost of GHP system in the first case was $13,285 more and the second case was $17,588 more than the installation costs of a conventional system. Further, the GHP system payback period depends on the whether the design uses a horizontal or vertical ground loop, and the designer and contractor’s quality and experience in performing the GHP work as the first case resulted in a payback period of 70 years while the second case had a payback period of only seven years. Findings show that when an appropriate installation occurs, GHP system can save consumption and energy costs for residential homes in hot and humid climates.

Abstract:

Extreme heat events cause significant societal impacts, prompting much concern and research about possible changes to their frequency and intensity as the climate warms. However, to date, extremes in air temperature have been emphasised at the expense of ‘heat-humidity’ indices, measures which incorporate the effect of atmospheric latent heat content on heat stress and provide a more complete picture of the thermal environment for human thermoregulation. This progress report restores balance by reviewing recent developments in the understanding of how heat-humidity indices have changed, and may continue to, as the climate warms further. The literature indicates that a concurrent rise in temperature and absolute humidity has already increased the frequency of potentially deadly conditions, and has reduced labour potential worldwide. More serious consequences may result if mitigation efforts are unsuccessful. The energetic basis of a heat-humidity perspective has permitted researchers to identify, for example, that by the end of the century, substantial parts of the Earth’s surface may be too hot and humid for human thermoregulation. Such consequences are avoided for less pessimistic scenarios of climate warming, but the societal impacts may still be very severe, as densely-populated low-latitude environments emerge as particularly at risk when a humid heat perspective is adopted. Counter to air temperature, changes in mean heat-humidity indices are actually amongst the largest worldwide at lower latitudes, where only small increases in the mean may be required to substantially enhance the frequency of dangerous conditions. The report concludes by outlining areas requiring improved process understanding, and it highlights the urgent role for societal adaptation if the worst impacts from rising humid heat are to be avoided.

Abstract:

Taiwan is located in the subtropical zone. The climate in summer is hot with high humidity. In order to establish a comfortable office, it needs a lot of active devices, such as: air conditioner to maintain the suitable indoor temperature and humidity. In this study, a business office in the South District Public Health Center, Taichung City is conducted. According to our findings for the office, although the measured indoor temperature was closer to a comfortable temperature during the winter, the occupants of the indoor space still felt excessively warm. By contrast, the occupants of the same space achieved thermal comfort during the summer. This implies that most of the office occupants preferred a cooler environment with a lower temperature. In addition, because the summers in Taiwan are humid and hot, the occupants of an indoor space tend to feel uncomfortable because of the high humidity regardless of whether the temperature is maintained in a comfortable zone. A lower temperature (approximately 21.2-23.9°C) indirectly reduces humidity, thereby making the occupants comfortable.

Abstract:

Alkali-activated materials (AAM) compared to Portland cement (PC) may significantly reduce the carbon dioxide emissions, as well as the consumption of non-renewable natural resources in civil engineering applications. Further environmental advantages are possible if natural aggregates used for mortars and concretes are replaced with residues and wastes from industrial or mining activities. This paper compares the performance of PC with AAM as binders in cementitious wall panels for external cladding in hot and humid climate. Three different cementitious matrices are proposed, consisting of either 100% Portland cement (PC), 100% alkali-activated metakaolin (MK) or 80/20 alkali-activated Metakaolin/Blastfurnace slag (80/20 MK/BFS). Mortars were produced with the addition of tailing from iron-ore mining activities in the state of Minas Gerais, Brazil, at an aggregate to binder ratio of 1.0 for all matrices. The thermal property determined for the three mortars was Thermal Conductivity using a heat flow meter (HFM) apparatus according to ISO 8301 (1999); their apparent density was also measured. After that, one-story house building simulation was carried out using the Energy Plus Software. The main room annual operative temperature provided by different panels used as cladding was compared to the adaptive comfort range established on ASHRAE Standard 55/2013 for a Brazilian and Portuguese hot and humid climate. According to the Climate Zone Definitions of ANSI/ASHRAE Standard 169/2006, Belo Horizonte (Brazil) and Funchal (Portugal) were selected as a sample of 2A zone that presents a hot and humid climate. Partial results of this research were presented in this paper. Results show that building simulations can effectively contribute to validate the selection of materials in the production of sustainable wall panels that provide suitable thermal conditions to the users in hot and humid climate.

Abstract:

Abstract Atrium is a popular architectural feature utilized widely by building designers and owners to bring various benefits such as adequate daylight, circulation spaces and surfaces for landscape applications. But atrium problems in tropical climates such as excessive daylight, glare and high temperature, which lead to increase building energy demand, have been reported. To avoid and reduce these unpleasant features, a side-lit atrium has been suggested. Although researchers proposed side-lit atrium to prevent common problems of atria, the lack of precedent research on this issue compels these authors to study atrium performance in hot and humid climate. So the research aims to examine two different atrium roof form types in terms of temperature and ventilation impacts in hot and humid climate of Malaysia using DesignBuilder as a simulation program. The results indicate lower temperature of side-lit model with better airflow pattern in comparison with top-lit model while the top-lit model provides higher air velocity at the air inlet and outlet.

Dari kajian ini dapat disimpulkan bahwa Prinsip Desain Arsitektur Bioklimatik pada Iklim Tropis terdiri dari 2 (dua) tipe meliputi Prinsip desain untuk bangunan pada daerah Iklim Tropika Basah ( Hot humid Climate ) dan Prinsip desain untuk bangunan pada daerah iklim Tropika kering ( Hot Arid Climate ). Hal ini menyesuaikan kondisi iklim dimana bangunan tersebut didesain.PRINCIPLES OF BIOCLIMATIC ARCHITECTURAL DESIGN IN THE TROPICAL CLIMATE The growth of building construction that does not consider natural conditions causes the potential for environmental degradation due to energy consumption in buildings, which and results in the depletion of natural resource. In addition to the occurrence of global climate change phenomena that foster energy-intensive for buildings to fulfill the physical comfort. This condition raises awareness of the importance of architectural design based on local natural conditions including local climatic conditions or the utilization of bioclimatic potential. Bioclimatic Architecture is a design approach that directs architects to get a design finish by considering the relationship between architectural forms and the climate environment of the area. This study discusses the principles of Bioclimatic Architecture design in tropical climates. Thus the theoretical framework is expected to be arranged related to the principles of architectural design in tropical climates. Tropical climate refers to the terminology of the geographical location of the area around the equator between the Tropic of Cancer and Tropic of Capricorn Lines. The method used in this study is a literature study or reference study. From this study it can be concluded that the principles of Bioclimatic Architectural Design in Tropical Climates consist of 2 (two) types, including design principles for buildings in the Hot Humid Climate area which has 2 seasons and design principles for buildings in dry tropical climate regions (Hot Arid Climate) with 4 seasons. These two design principles are influenced by several different climatic conditions between these two climatic regions. These two regions generally have high air temperatures; the difference is the diurnal temperature difference between the two climate regions. This condition requires a different response, especially in the design of the building envelope, where the design of the building envelope influences the level of heat gain and heat loss in the effort to create indoor thermal comfort in the building.

Abstract:

One comfort issue that considered to be the most important is thermal comfort. Air temperature is the most influential factor, and it is related to solar radiation and building's glazing. Besides thermal comfort, glazing is also needed to provide daylighting. Therefore, due to its relation to thermal comfort and daylighting, the glazing materials selection is crucial. Hence, by focusing on atrium in hot and humid climate, this study is aimed to examine a sufficient material with good thermal and daylighting performance. The results show that argon filled glazing is the most suitable material for atrium glazing in hot and humid climate. Argon filled glass has lowest U-value and total solar transmission than any other glazing materials simulated, but its light transmission is not too low so the daylight delivered still adequate to the standard. Accordingly, U-value, solar heat gain coefficient, and light transmission coefficient are concluded as the determinant factor in selecting glazing material.

Abstract:

This paper presents the experimental results of researching on plastic shrinkage (plastic deformation) and the effect of curing methods on the process of plastic shrinkage at the early stages when self-compacting concrete (SCC) starts setting and develops the strength. The experiments were carried out in two typical climatic conditions in Vietnam which are humid and dry. The experiments were conducted with two typical water/powder ratios of 0.3 and 0.35 and four cases of curing methods which are nylon membrane, watering, no-curing and soaking in water (the standard condition). Besides, the influences of plastic shrinkage at the early stages on strength development and occurrence of surface cracking of SCC were also investigated. The conclusions were drawn about the plastic deformation process and the curing method that might minimize plastic shrinkage of SCC, control surface cracking early, and ensure the quality and strength of SCC in the hot and humid climatic condition of Vietnam. Keywords: plastic shrinkage; self-compacting concrete; hot and humid climate; hardening process.

Abstract:

According to the work of Motakef and EI-Masri, the wall is divided into dry-wet-dry zones. Based on the heat and moisture transfer through porous media, considered the vapor condensation as a vapor sink, water source and heat source, coupled heat and moisture equations for wet zone were established. Closed-form analytical expressions for the condensation rate, moisture content and the time at which critical moisture content value is reached are obtained. The analysis has indicated that the condensation rate exhibits a strong dependence on the ratio of temperature drops across the wet zone to the square of that zone width and the maximum condensation rate value is reached at the boundary of wet zone close to lower temperature.

Abstract:

Natural ventilation, combined with a passive cooling system, can provide significant energy savings in the refrigeration of indoor spaces. The performance of these systems is highly dependent on outdoor climatic conditions. The objective of this study was to analyse the feasibility of a passive, downdraught, evaporative cooling system driven by solar chimneys in different climatic zones by using an experimentally validated simulation tool. This tool combined a ventilation model and a thermal model of the dwelling in which an empirical model of a direct evaporative system made of plastic mesh was implemented. For experimental validation of the combined model, sensors were installed in the dwelling and calibrated in the laboratory. The combined model was applied to Spanish and European cities with different climates. In the simulation, values of cooling energy per volume of air ranging between 0.53 Wh/m3 and 0.79 Wh/m3 were obtained for Alicante (hot climate with moderate humidity) and Madrid (hot and dry climate), respectively. In these locations, medium and high applicability was obtained, respectively, in comparison with Burgos (cold climate with moderate humidity) and Bilbao (cold and humid climate), which were low. The evaluation of the reference building in each location allowed establishing a classification in terms of performance, comfort and applicability for each climate.

Abstract:

Due to the different types of courtyards in vertical courtyard system (VCS), their impacts on thermal performance in office buildings may vary. To better understand this issue, this paper investigates the thermal performance impact of three typical vertical courtyards. A field case study was conducted in VCSs during two typical extreme hot days under hot-humid climate conditions. The results show that the vertical courtyards have significant cooling effects under hot-humid climatic conditions. Via testing on linear, integrated, and rooftop courtyard with fusion layout, the fusion one has an obviously positive impact on air temperature reduction (4.3 °C). Compared with the linear and integrated courtyards, the maximum air temperature difference of fusion layout is around 1.6 °C. The thermal radiation environment of the fusion layout was better than that of the other two (linear and integrated). Besides, the surface temperature of the pavements (wood panel) in the vertical courtyards can reach 47 °C, while the vegetation can lower it by 8 °C under the same weather conditions. These findings show that the courtyard with fusion layout is more suitable for extreme hot weather conditions.

Abstract:

The energy consumption of purely convective (i.e., various air volume (VAV) mixing ventilation) and combined radiant and convective HVAC systems (chilled ceiling combined with mixing ventilation—CCMV or personalized ventilation—CCPV) was investigated with multi-variant simulations carried out the IDA Indoor Climate and Energy software. We analyzed three different climates: temperate, hot and humid, and hot and dry. Our results show that the use of CCPV substantially reduced energy consumption compared to the conventional VAV system in hot climates. We also show that increasing the room temperature to 28 °C is an effective energy-saving strategy that can reduce consumption by as much as 40%. In the temperate climate, the VAV system was preferable because it used less energy as it benefited from outdoor air free-cooling. The control strategy of the supply temperature of personalized air had an impact on the energy demand of the HVAC system. The most efficient control strategy of the CCPV system was to increase the room temperature and keep the supply air temperature in the range of 20–22 °C. This approach consumed less energy than VAV or CCMV, and also improved the relative humidity in the hot climate.

Abstract:

In a hot-humid tropical climate, indoor thermal performance can be enhanced by comfort ventilation. Indoor ventilation depends upon building opening size. But risks involved in providing openings include ingress of mosquitoes and insects which thrive in the tropical climate. A practical and prevalent option to prevent insects in ventilated dwellings of the tropical, hot-humid city of Chennai, India is through the use of fly screens. Fly screens, when used over openings, prevent a certain quantum of solar radiation and wind from entering inside the rooms. Reduced direct solar radiation prevents the indoors from heating up, while reduced wind movement prevents the cross ventilation. Therefore, it is important to know the indoor thermal performance of ventilated rooms in the presence of fly screens with changing opening sizes. The criterion to evaluate indoor thermal performance in this paper is indoor air temperature. The aim of this research is to investigate the influence of fly screens on openings with varying sizes, in a naturally ventilated dwelling in the hot-humid climate of Chennai, India, during the summer period. The results of the study show that fly screens raise the indoor air temperature when openings are in the range of 100% to 35% of the room floor area. There is no significant change in the indoor air temperature when the opening sizes are less than 30% of the room floor area.

Abstract:

We calculate the influence of thermal mass and night ventilation on the reduction of the maximum indoor temperature in summer in residential buildings without using air-conditioning. The results are given for different locations in the hot-humid Mediterranean climate of Israel. We found that the maximum obtained indoor temperature reduction depends linearly on the temperature difference between day and night at the site. The results obtained show that one can predict the indoor temperature decrease, due to the thermal mass and night ventilation, from the simple and available data of the long term average temperature swing of the site, which is a common available data. The conclusion is that in the hot-humid climate of the Mediterranean coast, high thermal mass with night ventilation is effective for residential buildings with no air-conditioning provided the temperature swing is above 5°C, which is in general the case in this climate.

Abstract:

The objective of this research was to determine the proper thermal comfort in an atrium design for single-floor, medium-rise, and high-rise buildings based on different proportions, placements, window opening ratios, and internal condition systems. EDSL Tas software was used for the dynamic thermal simulation software models, and all were analyzed based on ASHRAE 55, ISO 7730, and EN 15251 standards to determine which dynamic thermal simulation models had thermal comfort in a hot and humid climate throughout the year. This research found that for naturally conditioned single-floor and medium-rise buildings, when the atrium proportion was 1/2 of the office proportion at the southeast and center atrium location, respectively, had maximum user satisfaction. When the building’s internal spaces were mechanically conditioned with a 1/3 and 1/4 atrium proportion of the office proportion in single-floor and medium-rise buildings, respectively, thermal comfort was acceptable, especially when the atrium was located in the center for single-floor and in the northeast for medium-rise buildings. However, the naturally conditioned high-rise building with a north-east atrium that was 1/4 of the office proportion and a mechanically conditioned high-rise with a center atrium 1/3 of the office proportion had the minimum dissatisfaction throughout the year.
