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.

The increasing energy demands in the building sector is considered as a main issue and has result both in the energy shortage and also environmental impact such as climate change and global warming. This demand is always increasing due to the high-rise level and also the need of thermal comfort. This paper aims to describe a passive approach to reduce the energy demand for a building through an improvement of the design of the thermal envelope. Within this work, we utilized the thermophysical properties of four building materials: three local materials (compressed earth, lateritic, and raw material) and one modern (Hollow cement) and an energy analysis of the building has been carried out. The numerical optimization of the building design has been performed dynamically by COMSOL Multiphysics software: case study of Ouagadougou and surface is 100m2. Also, the temporal variations in the inside of the room as well as the temperature of the walls and the ceiling with four different materials have been determined. The result shows that, for BLT, the maximum obtained around 22H is 308K, for Adobe it is 309K around 18H30, for BTC it was 309.2K at 20H and finally for cement block it is 310K around 18H. The mean average temperature of the building is low when we use local materials instead of modern one. Then, we conclude that, the use of local materials in the building design is an option for reducing the heat transfer into the room and at the energy consumption.

The Impact

Cantilevered concrete balcony slabs are being investigated in high-rise (MURBs) to control thermal bridging in terms of energy efficiency and thermal comfort where the use of a proprietary thermal break was the prime application as a solution to improving energy efficiency. This MRP investigated the thermal performance of using a lower U-value framed glazing condition and an insulated curb condition and developed assemblies in scenarios that were simulated in THERM, and focused on the technical performance of thermal comfort benefit of insulated curb condition of 12.7 mm thick EPS. Concrete surface temperatures were significantly increased in values from 4.8 °C to 9.6 °C and from 6.2 °C to 10.0 °C above balcony slab and from 6.7 °C to 10.8 °C below slab when an insulated curb condition was used in conventional scenarios and in a lower U-value framed condition scenario with no proprietary thermal break added. U-values are reduced 10% to 18% for the upper surface of balcony slab and 4% reduction of the overall U-values when an insulated curb condition is incorporated.

One passive approach that can significantly reduce energy usage in high-rise buildings is through the creation of non-air conditioned spaces such as transitional spaces. Optimizing passive design would reduce wastage associated with the building’s energy consumption. The study measures the thermal comfort of three types of transitional spaces (sky court, balcony, and rooftop) in a high-rise office building. Based on the assessment of Physiological Equivalent Temperature (PET), the outcome showed significant differences in PET in all locations in both wet and dry season. The effectiveness of such area can be improved with the contributions of landscape, maximizing natural ventilation and day lighting where possible.© 2016. The Authors.
