本研究探讨了英格兰的暖锋节能改造计划对低收入住宅冬季热舒适的影响。该分析是基于一项广泛的调查，从五个主要城市地区在英格兰在2001/02年和2002/03年的冬季选择约2500住宅。这些调查是在采用翻新隔热和节能供暖系统之前或之后进行的。连续11天，每天上午8点和下午7点记录两次自我报告的热舒适度（以七分制测量）和客厅和主卧室的室内温度。结果表明，暖锋有效地将平均室内温度从17.1°C提高到19.0°C，导致感觉热“舒适”或更温暖的家庭比例从36.4%提高到78.7%。暖锋还导致整个房屋的中性温度略有增加，即大多数居民感觉热中性的温度，从18.9°C增加到19.1°C，主要是由于减少了与更高的能源效率相关的服装水平。预测平均投票，这是ISO标准7730中的标准热舒适模型，预测中性温度为20.4°C，而18.9°C是平均暖锋家庭的理想温度。
This study investigates the effect of England's Warm Front energy efficient refurbishment scheme on winter thermal comfort in low-income dwellings. The analysis is based on an extensive survey of some 2500 dwellings selected from five major urban areas in England over the winters of 2001/02 and 2002/03. The surveys were carried out either before or after the introduction of retrofit insulation and energy efficient heating system. Self-reported thermal comfort (measured on a seven-point scale) and indoor temperature in the living room and in the main bedroom were recorded twice daily at 8 a.m. and 7 p.m. over 11 consecutive days. Results show that Warm Front was effective in increasing the mean indoor temperature from 17.1°C to 19.0°C leading to an increase in the proportion of households feeling thermally ‘comfortable’ or warmer from 36.4% to 78.7%. Warm Front also led to a slight increase in the whole house neutral temperature, i.e. the temperature at which most residents feel thermal neutrality, from 18.9°C to 19.1°C mainly from reduced clothing level associated with greater energy efficiency. Predicted Mean Vote, which is the standard thermal comfort model in ISO Standard 7730 predicted a higher neutral temperature of 20.4°C compared to 18.9°C found to be ideal among the average Warm Front households.
