The Ecohousing Building System is able to fulfil this need. Current insulation works on the principle of heat saturation, meaning that the insulation must first trap heat before it will work once it is saturated the heat is radiated back into the structure, this is a huge disadvantage in a hot climate.
The polyurethane core will work in both a hot and cold climate due to it insulating on an exclusion basis not a saturation basis. Look at a freezer the internal temperature is around minus 22°C, if you place your hand on the outside (the freezer wall is 50mm thick) it is room temperature, amazing and Ecohousing Panels are much thicker. There are also no thermal bridges in the Ecohousing Building System.
Ecohousing Building Systems also use widows that have very low u-values, stopping loss of energy through the windows.
Please view the graphs on the side showing energy required for heating and cooling in two similar sized houses, house one, the competitor house is a conventional built house, house two uses the Ecohousing Building System, the difference is significant. The saving in electricity translates to a saving of CO2 emissions for the environment and a saving of money for home owners and businesses.
The Building Codes of Australia have set down requirements for insulation (R values) in all aspects of a structure. On the next page is a map showing regions that Australia is broken up into, following are the tables for the required R values for each region, it can be seen that the Ecohousing Building Systems Panels far exceed the requirements. Ecohousing Building System R Values are calculated only on the polyurethane core, values increase if the coverings are included.
Global warming is a now a major issue around the world. Governments are currently looking at ways to reduce our carbon emissions; this will mean that for both the house hold and industry electricity prices will increase. There is now a need for structures to be more energy efficient then what is currently being built.
