The goal of this study is to characterize the potential for residential HVAC zone control technologies as a demand side management measure in FortisBC’s service area. FortisBC intends to use this study to determine the feasibility of launching a pilot and ultimately, to offer Energy Efficiency and Conservation funds for these technologies. This study assesses the space heating and cooling energy demand among FortisBC’s residential customers; characterizes market structure and the relevant market actors within BC; identifies key market barriers and potential program risks; quantifies potential upgrade performance and overall conservation potential; and reviews existing research and market interventions. Two broad categories of forced air HVAC zone control were examined in this study, each with their own unique costs and applications. This study employed a two-tiered research approach, through both primary and secondary research. Secondary research was undertaken by using the available literature and data to address baseline energy use, technology characteristics, and market structure. Primary research was undertaken through telephone interviews to fill gaps in the secondary literature, and to provide BC-specific market information.
