Indoor thermal environment of Hui style traditional houses is depended on surrounding environments, building layouts and envelope. Quantitative analysis of the effects of building layouts and envelope on indoor thermal environment is of great significance for preventions of traditional houses and design of new archaized houses. A field investigation was conducted on thirty-six traditional houses from nine villages in Wuyuan, and the typical buildings’ layout and envelope were determined. Four traditional buildings in different location in Wuyuan were selected for continual recording. The four buildings with four types of building layouts and envelope were analyzed by using local adaptive thermal comfort model, and the effects of building layouts and envelope of traditional buildings were clearly revealed. The most crucial way to improve indoor thermal environment in Hui style traditional buildings was raising the indoor air temperature.

“Desigrated” presented an attempt to integrate heat prevention strategies with low-ex cooling technologies, namely the desiccant and M-cycle evaporative cooling technology, in the form of a façade system for high-rise office buildings. The project targets to provide an alternative cooling solution for the hot and humid climate context of Bangkok. The results from experiments by various researchers are used as assumptions in developing the system, which was then evaluated through numerical methods and dynamic simulations. Being one of the prominent dehumidification technologies, a composite silica gel heat exchanger (CCHE) was implemented as the primary part of the façade system, while the M-cycle technology would also be implemented as a secondary cooling technique to cool down the supply air. The evaluation shows a promising result with up to 36% energy consumption reduction in comparison with the conventional cooling system, presenting itself as a transitioning tool in order to replace refrigerant cooling.

Hot Humid Climate

An effective passive cooling strategy is essential for reducing energy consumption in a residential building without ignoring thermal comfort. Therefore, a field measurement on the thermal performance of a corner terrace house in Kuala Lumpur was conducted to reveal the effectiveness of free running (FR) with four different approaches – no ventilation, full ventilation, day ventilation, and night ventilation. The measurement was done for all bedrooms and family area on the first floor. Also, mixed mode (MM) consisting of natural ventilation, mechanical ventilation with ceiling fan, and cooling with an air-conditioner that represents the actual condition of this house was also measured at living and dining area on the ground floor for comparison. The results reveal that FR from all approaches recorded a mean indoor air temperature of approximately 31 ∘C. The actual thermal condition of the house with MM on the ground floor was recorded at 30 ∘C, 1 ∘C lower than FR approach on the first floor. When compared with relevant international standards on predicting indoor comfort temperature based on outdoor temperature, FR was approximately 5 ∘C higher than predicted temperature based on American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 55 (2017), 3.4 ∘C higher than European Standard EN15251 and 1.5 ∘C higher than adaptive thermal comfort equation (ACE) for hot-humid climate. In comparison, MM performed better and was closer to relevant international standards, especially ACE for the hot-humid climate. As a conclusion, FR is not suitable for a hot-humid climate such as Malaysia to achieve a comfortable indoor thermal environment without any assisted ventilation use in MM.

To study the thermal environment of Dalian residences, in winter from 2011 to 2012 field investigation were conducted on indoor thermal environment, thermal sensation and adaptation measures. Thermal comfort instrument was used, and 102 subjective questionnaires in 36 families were collected. The acceptability to the thermal environment is 93.2%. The neutral temperature is 20.44°C, and the expected temperature is 20.81°C. 80% of the acceptable temperature range is 17.38-24.28°C. 57% of subjects think it is dry indoor and measures shall be taken for humidification.

The Impact

Abstract The climates of countries in the tropics tend to have high temperatures and humidity, and intense solar insulation. This condition gives the impact of discomfort for humans who are in the building. Implementing a passive cooling strategy can reduce energy use. Traditional architecture is one of the buildings that has been believed to apply natural cooling as a passive cooling design strategy. Based on several previous studies on the application of passive designs to obtain thermal comfort in the room, this study was conducted to assess the thermal comfort of Modifying Rumoh Aceh, which has not been widely studied. This study uses a direct measurement method in the field using an anemometer to measure temperature and airflow velocity. An Infrared/Thermometer Gun is also used to measure the surface temperature of materials (walls, roofs, and floors). Using the Climate Consultant Software to obtain annual climate condition data, AndrewMarsh 3-D Sunpath was also used to assess the orientation of buildings. Measurements were carried out for 3 days on 15 samples of Modifying Rumoh Aceh in Gampong Jawa, Kutaraja sub-district, Banda Aceh. The results obtained indicate an increase in room temperature by 7ºC from the standard comfort temperature based on SNI. The human ability to adapt to the environment can be seen in the perception of the Gampong Jawa community in accepting changes in the thermal environment by 47% with a sense of satisfaction. However, further research is needed to obtain a value for the level of satisfaction of the thermal environment in the tropics area.
