The Green Consideration - Energy Efficient Windows

“Saving the Planet, Saving you Money!”

Who are the culprits?

From this illustration it can be seen that surprisingly domestic housing is in the lead of the CO² generator hall of shame, followed by what most people would guess to be the main culprit, transport.

Company car tax now penalises the uneconomic juice guzzlers by taxing on the cars emissions, and it is the opinion of the author that it will not be long before this crosses over to the general public, with the introduction of energy ratings on cars.

It is difficult at first to understand why domestic housing makes it to such a notorious position at the top of the culprits tree, but consider this, every service in your property is creating CO² in the provision of creature comforts.

Power Station

All electrical goods in the home indirectly create CO². Producing this invisible form of energy generates large quantity of greenhouse gasses at power stations, gas central heating creates CO² which is exhausted through the boiler flu, even the supply of water uses energy in the sanitation plant and water pumping station, and therefore again creates more greenhouse gasses.

Over and above the greenhouse gasses that are created during the provision of the services which we now take for granted, houses in themselves add to this environmental problem.

Unfortunately houses are not insulated to a level that no heat is lost from the building, although obviously some domestic dwellings are better than others.

The image below is taken from infrared camera, indicating the areas of a property where heat escapes from the building envelope.

The scale of the heat loss ranges from hot white, through red to a cooler blue, and indicated the areas of greatest heat loss.

Heat loss in an average house

It is clear even to a layperson that the areas of greatest heat loss are the fenestration products within the property, the windows and doors..
