Indoor thermal conditions and the potential of energy conservation of naturally ventilated rooms in summer, China

Achieving thermal comfort in naturally ventilated rammed earth houses

“…The adaptive model was then adopted by American Society of Heating, Refrigerating and Air Conditioning Engineers' (ASHRAE) Standard 55 [21], in particular for investigating the thermal comfort of a naturally ventilated building, where there are opportunities for the occupants to adjust their thermal environment by, for example, opening the windows or turning on fans, and where the occupants are free to adapt their clothing to the indoor and/or outdoor thermal conditions. During the last decade, numerous studies have been conducted on the thermal comfort of naturally ventilated buildings around the world, such as studies from McCartney and Nicol [22] (in Europe), Indraganti [23], Indraganti et al [24], Indraganti and Rao [25] (in India), Candido et al [26] (in Brazil), Goto et al [27] (in Japan), Zhong et al [28] (in China), and Saman et al [29], as well as Soebarto and Bennetts [30] (in Australia).…”

Combined thermal and daylight analysis of a typical public rental housing development to fulfil green building guidance in Hong Kong

“…Natural ventilation is an effective strategy to promote indoor air quality, thermal comfort and energy conservation as validated by many researchers [4,6,7]. Investigations on indoor thermal comfort usually involve the coupling of multi-zone airflow modeling and building thermal simulation, requiring input parameters such as climate conditions, local environment, building physics, service systems, occupancy schedules and miscellaneous loads.…”

“…The criterion is satisfied if the predicted indoor operative temperature falls in the range of acceptability limits specified by ASHRAE 55 [2]. In naturally ventilated rooms, the traditional Predicted Mean Vote (PMV) indicator tailored for central air-conditioned spaces cannot apply well due to the allowable individual control over the thermal environment and psychological shift of comfort expectations [3,4]. ASHRAE Standard 55 therefore included the Adaptive Comfort Standard (ACS) to allow wider acceptable indoor temperature ranges for naturally ventilated building in warmer climate zones [5].…”
