This latest addition to the University of East Anglia Campus cost 20 per cent less to build than a conventional building of similar proportions and uses 80 per cent less energy.
An innovative energy management program has been successfully implemented at Mount Isa Mines, Mount Isa. Situated in Australia's north-western Queensland, remote from any electrical grids, Mount Isa Mines, owned by M.l.M. Holding Ltd, relies on electricity generated through its own two power stations. In 1988- 1990 the company was faced with a pressing requirement to reduce both operating costs and carbon dioxide emissions.
Concrete may be cold and hard, but some energy- efficient builders have been warming to insulating concrete forms (ICFs). As ICFs become more common, home performance professionals need to know how they're built and how well they work
The performance of a heat-pipe heat recovery unit was tested in a two-zone chamber with a horizontal partition. Air velocity was found to have a significant effect on the effectiveness of heat recovery. The effectiveness decreased with increasing air velocity. Simulation of air flow was carried out for the test chamber under natural ventilation conditions. It was shown that a heat-pipe heat exchanger can be used to reclaim exhaust heat in naturally ventilated buildings to effect energy conservation.
