Low-energy building design can contribute to dramatically reduced
energy usage and can be applied to all new building projects. This
paper explores the potential in Canada of applying available energy
efficient building technologies in cost-effective applications. The
objective was to determine the degree of energy reduction that can
easily be achieved in new building design and the associated costs. The
reference energy level was that specified by the minimum (or
prescriptive) requirements of the Canadian Model National Energy Code
for Buildings (MNECB) 1997. Costs and savings evaluated include energy,
capital and maintenance. The results indicate that significant energy
savings (greater than 50% reduction compared to the base case design)
with attractive economic returns are possible through careful selection
and application of existing technologies. The 50% energy reduction
relative to the MNECB is considered as the high performance building
threshold. It is possible to achieve 25% reduction compared to the base
case building with no incremental cost. With careful selection and
application of efficient building technologies at the early stages of
design, and adjustment of equipment sizing to account for reduced
demands, many designs result in energy savings of 30 to 40% with no
incremental cost.
