Precast Concrete Homes are better for the environment. Compared to other construction methods they use less energy to heat and cool. They also have a much longer life expectancy, allowing the carbon debt of their construction to be repaid over a longer period of time. All of these combine to reduce the carbon footprint of your new home.
Less CO2 during construction
During construction they require less transport to be used. As the finished walls are delivered to the site there is no need for multiple deliveries of various products or removal of excess waste to do with construction. Less transport equals less CO2.
As the panels are created in purpose built factories there is less waste in their construction. Formwork can be reused and excess water captured and recycled. Precise measurements of walls allows for minimal waste concrete to be created during manufacturing. Less waste equals less CO2
Less CO2 when lived in
Precast concrete walls have a much higher 6 star NatHERS rating compared to only 5.4 stars for brick veneer. Their high thermal mass means that heat is trapped in the walls in summer and not transferred into the house. During winter the heat is held and reflected back into the house. Lower heating and cooling costs means less CO2.
CO2 debt repaid over a longer period
Every construction method creates a carbon debt. How much of this gets repaid is dependent on how long the structure can stand before it needs to be replaced. The strength of precast concrete homes allows them to stand long after other homes have fallen. Longer lifespan means more CO2 debt is repaid.
