Abstract: According to the Auckland climate, building passive
design more focus on improving winter indoor thermal and health
conditions. Based on field study data of indoor air temperature and
relative humidity close to ceiling and floor of an insulated Auckland
townhouse with and without a whole home mechanical ventilation
system, this study is to analysis variation of indoor microclimate data
of an Auckland townhouse using or not using the mechanical
ventilation system to evaluate winter indoor thermal and health
conditions for the future house design with a mechanical ventilation
system.
Abstract: Auckland has a temperate climate with comfortable warm, dry summers and mild, wet winters. Auckland house design not only focus on winter thermal performance and indoor thermal condition, but also indoor moisture control, which is closely related to indirect health effects such as dust mites, fungi, etc. Most Auckland houses are designed to use temporary heating for winter indoor thermal comfort. Based on field study data of indoor microclimate conditions of two Auckland townhouses with a whole home mechanical ventilation system or a passive wind directional skylight vent, this study is to evaluate and compare indoor moisture conditions of two insulated townhouses only using temporary heating with different ventilation systems.
