Home construction has a large impact on global warming
According to the Environmental Resource Guide, produced by the American Institute of Architects, more than 30% of the energy consumed in the United States goes to making and maintaining buildings. This includes both operating energy –the energy required for space heating and cooling, lighting, refrigeration, water heating and other building functions–, and energy embodied in the physical structure.
The Canadian Mortgage and Housing Corporation, and SAR Engineering, have developed a computer program called “Optimize” that is designed to estimate the embodied energy, lifecycle energy, and environmental impact of a house.
Figures from the creators of the Optimize program provide the estimate that for a “standard house in Toronto with a 40-year life”, the total embodied energy is 2,352 Gj (One gigajoule is equivalent to about 1 million Btu)
The total operating energy over 40 years is 9,060 Gj, which results in expected operating energy of approximately 226 Gj per year. This means that a typical house will exist and operate for ten years before the total operating energy starts to outstrip the embodied energy contained in the building components!
The embodied energy of a house is not static, either. Very few houses go through an entire 40-year life span without undergoing remodeling projects that involve tearing out old materials and installing new ones, further increasing the embodied energy contained within a house.
Since the combustion of one Gigajoule of natural gas produces 52.8 Kilograms of CO2, the construction of a typical home contributes to global warming with 124,186 Kilograms of greenhouse gases.
A similar home built with the Terra-Steel System developed and patented by Sunway Homes reduces a 40% on the embodied energy, because walls are built with the greenest of all construction materials: earth’s soil.
Trees are like lungs for our planet. They absorb CO2, reducing global warming and release Oxigen.
The timber industry always responds to the critics saying: “trees grow back”, but according to a study by Albert Meier and David Duffy from the University of Georgia, clearcut decimates the biodiversity of a forest. The Popular Science Magazine, reporting on the findings of the study, came to the conclusion that: “Trees grow back. Ecosystems probably not”
Sunway Homes proudly supports environmental issues and believes their product will help preserve the American, Mexican and Canadian forests.
In the United States, only 4% of the virgin forests are still alive. To build an average house it is necessary to cut 8 to 10 mature trees.
Humanity needs to stop global warming NOW!
Internationally renowned photographer Yann Arthus-Bertrand has produced what we consider is the most influential video in history intended to save our planet. The name of the movie is HOME. The following is the trailer, and below you will find a link to see this movie in YouTube.
We invite you to enjoy this magnificent documentary in full screen mode.
Home poses the prospect that unless we act quickly, we risk losing the only home we may ever have: Our Planet Earth.
