Summary

As the urbanization trend prevails worldwide, more people are moving to major metropolitan areas, causing housing resources to be in urgent demand. Micro-apartments, designed to offer a minimalist lifestyle while also addressing growing housing needs, have become increasingly popular among home seekers. Due to smaller household sizes, tiny homes, occupying less land area, also become more prevalent among families. Meanwhile, individuals primarily spend their time indoors, and with more people adopting work-from-home lifestyles, ensuring a highquality and comfortable indoor environment becomes crucial for indoor occupants. Many studies have highlighted that the activities of occupants significantly influence indoor environmental quality (IEQ) and energy consumption in buildings. This study performed a comprehensive evaluation of IEQ satisfaction survey and energy usage measurement in the Purdue zEDGE Tiny House as a controlled facility to represent urban and rural compact living spaces. Twenty full-scale experiments were conducted during the winter season. The study first evaluated participants’ perception of IEQ factors, with thermal comfort and indoor air quality (IAQ) emerging as top priorities.
It then examined energy adaptive behavior to understand maintenance of comfortable indoor conditions, noting primary adaptive strategies included heating, ventilation, and artificial lighting. The study then measured IEQ and energy consumption, evaluating occupants’ IEQ satisfaction levels. The average energy use was recorded at 10.3 kWh, with occupants generally satisfied with IEQ in the zEDGE Tiny House. Analysis indicated that indoor heating and electric cooking resulted in significant energy consumption, potentially exposing occupants to high indoor air pollutant levels in a compact living space.
