Start with your existing house to save energy, money and greenhouse gas emissions.  Come and hear Canada’s legendary figure in energy efficient construction present the findings from his latest project — the renovation of a 1950’s 4-plex in Regina.  This extensive retrofit included a vapour barrier, new wall and roof insulation, and air-to-air heat exchanger as well as new windows, siding and roofing.  His presentation will cover some of the technical details, economics and performance figures from this well-documented project.


Harold Orr is a retired engineer and a carpenter with a distinguished career with the Division of Building Research with the National Research Council in Saskatoon.  Harold has been associated with a number of key innovations in the field of low energy houses including practical air sealing technologies, the astounding Saskatchewan Energy Conservation House (in 1978, which started the whole energy-efficient housing industry), double-wall retrofits of existing houses, the HOTCAN computer program for calculating house performance, air tightness requirements for buildings and a host of other innovations.  His work has revolutionized energy-efficient housing around the world and made Canada the world leader that it is.
