[Greenbuilding] Energy calculations

The HVAC contractor who did the actual work would qualify to revise the
calculations to see if they meet the 58k BTU available (shouldn’t be
difficult to meet that with even a rough model) . All the inspector wants is
a letter in the file.

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
