Introduction
The world’s energy resources are being consumed at a significant rate that will result in the depletion of
non-renewable resources. It is imperative that energy be conserved. The building sector, through its use
of energy, can represent up to 40 % of the total energy consumed (in mild climates, where heating and
cooling correspond to the major energy demand in buildings). Conservation of energy in buildings can
result in a slowing down of non-renewable resource usage and consequently of the build-up of
greenhouse gases.
A critical contribution to the conservation of energy in buildings is made by minimizing the heat loss from
a building. This is achieved by creating building envelopes that are both airtight and highly insulated.
