Although differences in assumptions and
input data make comparisons difficult, a
study of a Toronto building produced
different results. RETScreen’s passive solar
energy module was used for the Toronto
building. The RetScreen model of a 110 m2
(1,184 sq. ft.), south-facing suite in
Toronto with 7.2 m2 (75 sq. ft.) of windows
(similar to the suites in Halifax) gave the
following results. (Increases in cooling load
were not calculated, as this was assumed to
be an unconditioned building.):
