“…The keyword and literature search yielded many papers that examined thermal comfort above 40% or 60% RH (Ahmed, 2003;Wong and Khoo, 2003;Hwang et al, 2006;Han et al, 2007;Becker and Paciuk, 2009;Shinohara et al, 2014). Six papers were identified that studied thermal comfort in chambers with set environmental conditions at low (RH <40%) humidities (Nevins et al, 1966;de Dear et al, 1989;Fang et al, 1998;Sunwoo et al, 2006a;Sunwoo et al, 2006b;Tsutsumi et al, 2007), and noted the effects of clothing on thermal comfort.…”

Nearly 600 papers were located in citation and keyword searches regarding the effects of humidity on comfort, health, and indoor environmental quality (IEQ). Of these, around 70 papers reported the effects of low humidity (RH≤40%) and were analyzed in detail. Information in some categories was well chronicled, while other categories had significant knowledge gaps.Low humidity decreased house dust mite allergens. Due to different envelopes, generalizations could not be made for all bacteria and viruses. However, lower humidity increased virus survival for influenza. For comfort, low humidity had little effect on thermal comfort, but skin dryness, eye irritation, and static electricity increased as humidity decreased. For IEQ, low humidity had non-uniform effects on volatile organic compound (VOC) emissions and perceived indoor air quality. Across many low humidity studies, ventilation rates and exposure times were noted as confounding variables. A majority of studies that used human subjects utilized exposure times of three hours or less with adult subjects; few studies used children, adolescents, or elderly subjects.

“…Thermal neutrality and thermal preferences differ [71], with tropical dwellers preferring "cool" rather than "neutral" temperatures. Data from thermal preference studies in Indonesia, Singapore and Southern China [72][73][74] were fitted to five parameter logistic regression models (Appendix A) to construct Figure 7. Air-flow and humidity are important to thermal comfort and preferences but were not recorded in the thermal preference studies used for the model.…”

“…Effective ventilation can enable indoor temperatures to match outdoor temperatures at night when residential AC usage is most prevalent but this alone will not alter AC usage if ambient temperatures already exceed residents' thermal preferences. Three global climate change scenarios developed by the IPCC were explored: A1FI (assuming rapid economic growth based on fossil fuel- [72][73][74]. Curves were fitted to data using four or five parameter logistic equations.…”

The Impact of Subsidies on the Prevalence of Climate-Sensitive Residential Buildings in Malaysia

Dependence on air-conditioning (AC) for residential cooling and ventilation is a health and sustainability challenge. In hot temperatures, climate-sensitive buildings (CSB) can complement and/or substitute for AC usage in achieving thermal comfort. Many countries facing such conditions-particularly in tropical climates-are developing quickly, with rising populations and income creating demand for new housing and AC. This presents a window for adoption of CSB but could also result in long term lock-in of AC-dependent buildings. Here, a simple system dynamics model is used to explore the potential and limitations of subsidies to affect futures of housing stock and night-time AC usage in Malaysia. The effectiveness of subsidies in achieving high uptake of CSB and resulting health benefits is highly dependent on homebuyer willingness to pay (WTP). A detailed understanding of WTP in the Malaysian context and factors that can shift WTP is necessary to determine if CSB subsidies can be a good policy mechanism for achieving CSB uptake.

“…Studies have shown that the PMV either underestimates or over-estimates the thermal sensation of occupants. Reference [18] and [19] for instance observed the underestimation of thermal sensation by PMV model in their respective studies. Air temperature is often taken as the main design parameter for thermal comfort.…”
