heat loads (during cooling) are usually higher than external heat gain which
means the building is “trapping heat” . This happened to one of our
models where we have a constant 120 kW electrical heat generation from an
industrial control/electrical room (<st1:place w:st="on">Southern Ontario</st1:place>
climate ). The increased insulation was actually increasing the cooling load
significantly and we had to find an optimum insulation value. <o:p></o:p></span></font></p>
