Improving the Building Energy Efficiency and Thermal Comfort through the Design of Walls in Compressed Earth Blocks of Agricultural and Biopolymer Residues Masonry: A Recent Study | Chapter 5 | Research Developments in Science and Technology Vol. 9

In this study, the effect of wall building materials on hygrothermal behaviour and energy efficiency in homes is examined. Nowadays, the majority of individuals make significant financial investments to upgrade the interior conditions of their buildings in order to live in a posh setting. Three different types of construction materials were used to produce the building design in the Design Builder interface for the wall: CSEB of fonio straw and Shea butter cakes, cement blocks, and cut laterite blocks. The total amount of energy needed for building cooling was calculated using dynamic modelling with Energy Plus software. We conducted a simulation utilising the weather conditions in Ouagadougou City, and we found that the thermal behaviour of the housing is affected by

in earth-based simulations, the wall. The results show that, in comparison to homes with a cement or cut laterite block masonry wall, the number of warm thermal discomfort hours and cooling energy loads are decreased in homes with a CSEB of fonio straw and Shea butter cakes by an average of 10.60 percent and 93.86 percent, respectively. The earth-based influence of this wall allows for an average interior temperature and indoor operating temperature of 28.64°C and 25.82°C, respectively, on the inside environment. The average inside temperature peaks dampening at 6.54°C (i.e. 22.83 percent). Because of this, these CSEB walls provide a useful contribution to the creation of sustainable homes in a hot climate.

Evaluating the Perception of Ventilation for Thermal Comfort in Senate Buildings in Nigeria Universities: A Case Study| Chapter 8 | Current Research in Language, Literature and Education Vol.4

This Study looks at the subjective feelings of the occupants of the Senate Buildings in selected Universities in order ameliorate the effect of thermal discomfort for the occupants. One of the most important factors in office building ventilation is window condition. The study's goal was to assess natural ventilation in Senate buildings at selected universities in South-West Nigeria. The study used questionnaires and surveys to gather information on the subjective feelings of the occupants regarding the effects of thermal opening and thermal comfort in Senate building offices. Direct observation was used to gather information about the physical characteristics of the chosen buildings. There has been little research on the study of occupants' feelings in buildings in relation to openings in buildings. According to the survey results, 34.0 percent of the windows were casement and 30.0 percent were projected, 25.5% were sliding; while 9.5% were the louvred type. According to the study, 73.8 percent of respondents preferred casement windows over other window types due to their ease of operation and improved thermal comfort for occupants. The study concluded that, when properly sized, casement windows are the most effective at mitigating the effects of thermal discomfort in Senate buildings.

Determining the Mechanism on Ventilation for Thermal Comfort in Residential Buildings: A Case of Government Housing Estates in Nigeria | Chapter 12 | New Approaches in Engineering Research Vol. 15

 Natural ventilation has been identified as an energy-efficient option for lowering building energy use, achieving thermal comfort, and preserving a healthy interior environment. The study looks at the ventilation system in residential structures for thermal comfort in a selected government housing estate in south-west Nigeria. As a result, the study identifies landscape aspects as well as consumers' levels of interest and desirability in using landscape features in their environments. There has been minimal research on the mechanics of ventilation in residential structures for thermal comfort. According to the survey findings, 78.0 percent of natural ventilation mechanisms were windows, 12.5 percent were soft landscape components, and 9.5 percent were a combination of window and courtyard. As a result, the study concluded that windows of adequate size and landscape elements should be included in residential buildings to increase natural ventilation.

Determining the Impact of Microclimatic Variables on Human Comfort; A Case Study of Akure Urban Environment, Nigeria | Chapter 3 | Challenging Issues on Environment and Earth Science Vol. 7

The physiological equivalent temperature (PET) index was used in this study to assess differences in physiologic comfort of people living in the Akure metropolitan setting using a Geographic Information System (GIS). PET values were calculated from both microclimatic and thermophysiological data using the Rayman model, which may provide mean radiant temperature and PET, which are important in thermo-physiological heat balance models. It also looked at the responses of a sampled population to various land uses, which was the major goal of the study. the study: that is, to examine the geographical pattern of human comfort in the study region using a physiological equivalent temperature index across various land use types. As a result of diverse activities in each of the land uses evaluated, thermal heat stress was discovered geographically and temporally (6:00; 12:00; and 18:00 local standard time, LST) within the research area as high as (41-55) °C. The results also revealed that many of the respondents had not yet grasped the concept of thermal stress. as well as the consequences. The study's conclusion is that data should be collected during the dry season and that tree planting and urban greenery should be improved.

Analyzing Energy-Saving Measures and Key Metrics for Enhancing Cooling Performance in Atrium Buildings | Chapter 10 | New Approaches in Engineering Research Vol. 8

 Atriums are increasingly being used by professional designers and owners to give a number of benefits, such as sufficient sunlight, circulation areas, and surfaces for gardening applications. The space conditioning of atriums, which have a relatively big volume when compared to standard commercial and institutional spaces, is one of the most critical challenges with this popular architectural feature. Unless proper design strategies are used, adequately conditioned atriums could result in excessive energy use. It can be difficult to attain both high thermal comfort and low energy consumption at the same time. The potential for energy savings from precise temperature management indoors reinforces the case for investigating the applicability of the universal comfort temperatures advocated by international comfort standards. The goal of this article is to assess energy saving strategies that have aided in the achievement of architectural design characteristics while also supporting thermal environment conditions. A systematic analysis of elements for energy saving identified design aspects that have influenced the development of a comfortable atmosphere through a literature review. Environmental considerations in the installation of architectural characteristics in atriums have been characterised as daylighting, acoustics, natural ventilation, and temperature regulation. The results would help architects and designers choose the most energy-efficient atrium building type, as well as optimise the controlled atmosphere during the initial design stage.

Bioclimatic Analysis Based on the Climate of Greece: An Approach towards Minimization of Energy Consumption in Buildings | Chapter 6 | Current Approaches in Science and Technology Research Vol. 7

 energy and other environmental sources, as well as various natural climate phenomena. As a result, energy consumption in the building sector is reduced, while building users are provided with thermal comfort. This work includes a bioclimatic analysis of regions of Greece with varying climatic features. KENAK 2017 classifies Greece's prefectures into four climate zones: A, B, C, and D are the letter combinations. The bioclimatic study is carried out with the help of the bioclimatic charts created by the Olgyay brothers Victor and Aladar. Victor and Aladar Olgyay's quantitative and qualitative bioclimatic charts are created for two Prefectures in each climate zone using relevant climatic data from the National Meteorological Service. The average values of the passive demands for sun radiation, shade, wind, and humidity are calculated for each month and climate zone. utilizing quantitative bioclimatic charts Qualitative bioclimatic charts are used to define passive heating and cooling strategies. The regression lines and second degree polynomials equations are then generated by using monthly charts of solar, radiant, wind, and humidity demands for each climate zone. These formulae can be used to easily compute passive thermal and cooling requirements for each month, and the results can be applied to areas with similar climates. As a result, the findings of this study can be used as a guide for building designers. They will be aware of the passive heating and cooling techniques that must be used in each building based on its climatic zone.
