This paper presents a techno-economic analysis of deep energy retrofit strategies aimed at improving a typical existing home to a Net Zero Ready (NZR) level. Three distinct pathways are selected to examine the impact of modifying the mechanical system and building envelope. Each pathway is analyzed in TRNSYS for both the Montreal and Vancouver regions using a validated housing model. A techno-economic analysis methodology then combines the calculated annual energy costs with the associated material and labour costs for each option.

The climate indicators that are currently used in the building energy area, summations of degree-days, are not suitable for net-zero and low energy analysis, because they fail to characterize the building-climate interaction. This paper presents a new set of climate indicators that focuses on overall climate and building performance, as well as specific climate statistics that have a relevant impact in NZEB and passive buildings. The proposed framework is based on three interrelated energy performance indicators.
