We live in a world where every year, almost 7 billion tonnes of greenhouse gases are emitted into the atmosphere.  Much of this is caused by energy waste.  In Australia, the average household (not including transport) is responsible for 6 to12 tonnes of CO₂ yearly emissions, depending on which state of Australia they live in.  This is the highest per capita levels in the world.  We have done energy audits where households have emitted more than 23 tonnes per annum!

It is very easy, with the use of elegantly simple solutions, to reduce this by 75% or more. With off the shelf solar power technology, it is not only possible to reduce this pollution completely, but also to reduce your neighbours' emissions as well!  Not only can you say goodbye to your power bills, you might even get a cheque in the mail from your energy supplier.  Don’t forget to ask us how federal and state governments are now subsidising this.

Some people believe that living with energy efficiency means doing without.  Nothing could be further from the truth.  Energy efficient homes are usually 5°C cooler in summerAND 5°C warmer in winter.  Mike Stasse knows how to turn 5° into 10°C! By designing for natural ventilation and lighting, GREENhouse design homes are radically more comfortable than conventional homes.

This chart shows how on e of our high thermal mass/externally insulated designs performs in Brisbane's subtropical climate zone.  Even though this site's temperature often rises above 40°C in summer, this building's inside temperature never rises above 27°C.  In winter, Brisbane's temperature can fall to below 5°C, yet this house never gets cooler than 20°C!

This is no miracle, just the judicious use of appropriate building materials, commonsense siting, and fine tuning of window sizes.
 
 
 
 
 
 

By way of comparison, this next chart shows how a brick veneer and dark tile roofed house performs when inappropriately sited, built without eaves (an increasingly worrying trend), and 'insulated' with mere sarking in the same climate zone.  This style of building is currently marketed Australia wide as the 'Dream Home', and, it appears, these builders seem to think that they are appropriate regardless of whether they are to be built in Hobart, Perth, or Darwin.

The blue bars in this chart show periods when (again in Brisbane) the house is cooler than the deemed 'comfort zone' (shown in yellow), and the red bars show when the house is hotter.

You'll notice how this house remains above 36°C for over 400 hours a year!!!!

You'll also notice that the yellow comfort band bars for the inefficient house only occur for about a third of the year, whilst in our design (above), the yellow bars are a year round occurence.

All those blue and red bars cost a lot of money in both capital and running expenditures to get rid of.  They are the true signs of inefficiency.
