A model for estimating the potential for energy and associated cost savings has been developed based on current information and audited test results. Model results show that microwave-assisted gas firing for the clay industry provides favourable payback periods based on energy cost reductions, in addition to environmental benefits.

Investigations into lightweight and heavyweight constructions in relation to potentially increasing temperatures due to climate change show that lightweight construction leads to increased internal temperatures and greater levels of discomfort. The case for high thermal mass buildings in saving energy is not confirmed, but careful consideration should be given to insulation, ventilation and solar gain.
