June 2011 to June 2012 all consumption was at 55kw/h M2 per year. We are running solar hot water and ground loop tempering for HRV. It was a warm winter I should translate this into 5600 degree days from (4678 June to June) for an accurate picture.

Then it becomes pretty obvious that small changes can have big savings over the longer term. If the break-even point is less than 20 years (5% straight annual return on investment), that’s a better return than most stocks these days. When you apply the upgrade costs of feasible improvements to a 25 year mortgage at today’s low rates, then deduct the energy savings, you’ll usually end up in a cash-positive position from day 1 – in other words, the better house actually costs less to own than the cheaper house. It’s our abilities to properly explain this to people that will determine whether high performance homes really catch on among regular homebuyers or remain the domain of elite greenies.</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Ross</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <a href="mailto:pbc-members-bounces@lists.passivebuildings.ca">pbc</a><span class=squiggly><a href="mailto:pbc-members-bounces@lists.passivebuildings.ca">-members-bounces@lists.passivebuildings.ca</a></span> <a href="mailto:[mailto:pbc-members-bounces@lists.passivebuildings.ca]">[mailto:pbc-members-bounces@lists.passivebuildings.ca]</a> <b>On Behalf Of </b>Stuart Fix<br><b>Sent:</b> Wednesday, July 04, 2012 1:01 PM<br><b>To:</b> Passive Buildings Canada Members<br><b>Subject:</b> [PBC-members] Energuide Calculation</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p></div></div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hi Mike,</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>See attached, this is an extraction from a larger document, but these 4 pages outline an Energuide rating calculation.

I realize the Canadian Home Builders Association, of which I'm a member, will do everything in their power to fight this progression and will try to prevent houses from becoming more energy efficient than they already are (at the will of big builders and developers).

CHBA even gives builders energy-saving credit for tearing down thousands of older houses and replacing them with slightly more energy efficient “infill”! While the housing industry crows about how much progress they've made in 30 years, the fact is they're still using 2x6 @ 16” o.c., batt insulation and leaky poly air / vapour barriers from back in the 1980s despite irrefutable evidence that we can do better, and should do better in a cold climate.

They strive to build the best houses they can BASED ON WHAT THE BUYER WILL PAY FOR. Many of the builders I work with would be glad to build only super-energy-efficient homes, if they didn’t have to do so with their own money, and although a small minority of homebuyers will pay extra for ENERGY STAR, R-2000 and Passive Houses, the vast majority simply want the lowest level of energy efficiency allowed by Code, because first-cost is all they understand.</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal style='line-height:21.6pt;background:white'><span lang=EN style='font-size:10.5pt;font-family:"Tahoma","sans-serif";color:#1F497D'>Buyers won't make it happen, builders can't make it happen. So what's the solution? Although I'm a libertarian at heart, in this case we need decisive government intervention. Only through progressive and predictable Code increases in energy efficiency, where all builders are on the same level playing field, will we be able to cut the energy use of homes by over 75%, thereby preparing the stage for net-zero-energy homes for the next generation, homes that will not only meet all their own energy needs but also charge up the family car while emitting no greenhouse gases. Amory Lovins has shown it can be done now, if only there were enough political will.</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p></o:p></span></p><p class=MsoNormal style='line-height:21.6pt;background:white'><span lang=EN style='font-size:10.5pt;font-family:"Tahoma","sans-serif";color:#1F497D'>While the housing industry sanctions status quo houses as being the pinnacle of energy-efficiency achievement based on a flimsy record of incidental energy efficiency improvements to components while barely making any changes to the actual building envelope, and defends housing’s unnecessary greenhouse gas emissions based on a comparison with increasing emissions in other sectors, there is a small minority of people who are ready to follow the lead of the Europeans, and the Americans, in building houses we can be proud to leave our grandchildren – after all, how long should a well-built house last?
