The BBSA Shade Project proves that blinds offer the most cost effective energy savings
Over the years we have seen energy prices rise quite significantly and as a result we have seen the domestic energy companies rush to increase domestic and commercial tariffs to heights never reached before.
All energy companies have announced repeated price increases over the last few years, and none will deny that prices will continue to increase.
Our industry has spent a great deal of time and money working to convince the commercial consumer to install the correct shading systems to reduce the amount of solar gain experienced within commercial buildings thereby reducing the need and reliance on expensive to buy and operate air conditioning units....
But what about the home owner?
How can you benefit from the correct selection of window blind systems and fabrics? Well many fabric manufacturers have been considering this for some time now. The starting point was that if the fabrics produced had special properties that could reduce heat build up, then there must be positive savings to be made by installing fabrics which are proven to have special properties to reduce heat loss. A reduction on heat loss is far more significant to home owners as this can reduce the energy required to heat their homes.
Take a look at the video below... it provides the difficult information that you need to know in an easy to digest format!
Shade Specifier Database
Solar shading has a very important part to play in reducing energy consumption in buildings, thereby reducing emissions and helping with regulatory compliance.
Shade Specifier is an important project of the BBSA (British Blinds and Shutter Association) to prove the energy saving benefits of solar shading. It is understood by many that blinds and shutters reduce solar gain in the summer and heat loss in the winter in addition to controlling glare and providing privacy.
However, how do you know what is the best option for you and how do you know how the material will perform? The BBSA has created a database that will allow you to do just that. At this stage of the project, we do not recommend that home owners try to use the database to work out savings. In the future, the BBSA will publish easy to understand energy labelling which can be used on fabrics (much like the labels one sees on domestic appliances). Architects and building designers may be able to make more sense of the database in it's current format.
Calculated to European Standards (the same used by the glazing industry) this database will allow you to chose the glazing, the material in the blind or shutter and whether the blind/shutter is fitted internally or externally and in the case of blind, mid-pane.
You can see:
- U-value – improvement in heat retention properties of the glazing and blind/shutter combined
- Gtot – the heat rejecting properties of the glazing and the blind and shutter combined
- Tvis – the light transmission of the glazing combined with the blind and shutter
