Ashden.org is one of my all time favorite sites. You can spend days researching their extensive website for award winning designs. This is top quality information, folks.
“Low energy buildings use passive techniques, such as optimal solar gain, and advanced active systems, such as mechanical ventilation with heat recovery, to create comfortable internal environments that have low energy demand and associated greenhouse gas emissions. Some low energy buildings use renewable energy generation to further reduce or eliminate their greenhouse gas emissions in use.
– Buildings account for about 45% of UK CO2 emissions.
– Good design can cut CO2 and energy bills by nearly two thirds.
– Incorporating renewable energy as well can give buildings that produce no net CO2 in use.
