Last week, my partner Andrew posted a blog about the LED market and discussed some emerging technologies that will revolutionize the lighting market. I want to expand on that topic and provide some insight into energy efficient green buildings.
Buildings are huge consumers of energy. The US Department of Energy estimates that, in the US alone, buildings use nearly 40 quadrillion Btu of energy for space heating and cooling, lighting and appliances. This represents approximately 39% of the total energy consumed in the US and 38% of a building’s energy is consumed for heating and cooling. The Building Technology & Urban Systems Department at Berkeley Labs states that buildings consume 71% of US electricity, 53% of US natural gas and emit 40% of US greenhouse gases. There is clearly room for improvement.
