Take advantage of the sun’s free rays to subsidise your hot water costs. Enjoy guilt free showers while the cost of power goes up.
Making good use of materials correctly orientated to the sun to reduce your heating costs. Thermal mass walls and insulated concrete floors collect warmth during the day and disperse it at night.
Use the maximum insulation available to the roof, wall and floor cavities. This will make a great difference in reducing your costs for heating and cooling by improving the balance of temperature in your home between night and day and between the seasons. We can also incorporate thermal bridging breaks in the structure to reduce heat loss
This is essential if you want to achieve good thermal performance for your home. It works in association with good insulation and helps control humidity and noise. Well fitting curtains and blinds also improve thermal performance.
Before thinking about energy efficient lights, make sure that you utilise natural daylight as best as possible. It’s free, it feels good and it’s the ultimate sustainable choice. For artificial lighting avoid excessive numbers of down-lights. They use a lot more electricity and can allow heat to escape. Use ceiling mounted or wall lights with long life bulbs.

Initial capital cost may be higher at the time of building, but over the life of the building will produce savings. We also encourage you to look at what is really important. A well-designed house that is say 20sq.m smaller may cover the cost of extra insulation, solar hot water and double-glazing. And you get your investment usually back on day 1: Recent overseas research with real estate companies have proven that people are prepared to pay a premium of between 5-10% for a house which is energy efficient and sustainable.
