Does anyone on the list know of someone who can do energy calculations for an as built that can help us pass a final building inspection.

We have been building just north of Toronto (Orangeville area) and just had our final inspection. To get the building permit in 2010 we had an energy calculation done and it specified we needed 75,000 BTU/h. I suspect that the calculations were for a house built to code.  We did not build to code but rather followed a lot of good advice in building the house from people on this site ranging from an ideal site orientation, triple glazed tuned windows, persist building envelope, tight (<0.3 ach) etc.).  Everything is passed but for the HVAC calculations and the only thing is that we do not have the 75000 BTU/h heating specified in the permit. I have installed 2 Fujitsu 12 RLS mini splits (14,000 BTU heating ea.) and this is more than adequate and keeps the house at 20-22 0C throughout the winter.  I added an additional Mitsubishi mini split (18 NAH) (20,000 BTU/h this spring as both a backup system and to try and keep the inspector happy.

He was very sympathetic and also recognized that I do not need more heat but rather an as built calculation by a certified person taking into account the as built specifications that shows that the 48,000 BTU/h installed capacity is sufficient. 

In summary does anyone know someone who can do these calculations in the area suitable for meeting inspection needs? 

 

Thanks Don
