Simulation Results
■ Using a higher Solar Heat Gain
Coefficient (SHGC) glazing reduced
the total annual heating cost by three
to four per cent.
■ Orienting the building along the long
east–west axis instead of north–south
axis reduced annual heating cost by
about one per cent.
■ Increasing the window area on the
south-facing suites reduced annual
heating cost by less than one per cent.
■ Increasing the interior mass reduced
annual heating cost by about two per
cent.
