Full Description

Thermal comfort plays a vital role in the well being of occupants and is therefore considered very important to control. This paper comparesthermal comfort of the semi-detached Archetype Sustainable Homes at the Kortright Centre in Vaughn, Ontario. This was done by following therequirements of ASHRAE Standard 55 - 2010 Thermal Environmental Conditions for Human Occupancy. These semi-detached homes havesimilar building envelope components however differ in HVAC technologies. The intent of House A is to demonstrate practices and technologiescurrently in the residential building market. The intent of House B is to demonstrate advanced technologies such as thermal mass, zoned spaceconditioning and in-floor heating that could be used by mass markets in the future. Results indicate House B is comfortable to a greater percent ofthe population. House A did not meet the draft criteria under the local thermal discomfort requirement. This was a result of the combination ofdrafts and lower air temperature during heating season measurements which reduced comfort levels. It is important to understand what makes ahome comfortable so that improvements to energy efficiency and demand management can be realized.
