Every Little Helps on the Path to Carbon Neutrality
Reversing cameras, left, right and centre mirrors … a glance over your shoulder can still be what makes that all essential difference. So too with building energy performance. It is probably best to just assume that your building has an energy performance blind spot. The next steps are to find it and then fix it. This was our approach to Tesco’s National Distribution Centre when ...

Define ‘green’ please
Describing a building as ‘green’ makes a lot of people cringe. The word is overused. And what does it mean exactly? Serious efforts are underway to move away from the hype and offer a more specific analysis of a building’s energy performance. Think nutritional labels for food, except in kilowatt-hours instead of calories. In fact, more than 50 national, regional and local ...

Is the energy efficiency service markets still MUSH?
We hear a lot about energy efficiency these days, but who is actually pursuing it? In recent years most of the big players that install efficiency measures, the energy service companies (ESCos), have found work largely in the MUSH market: municipal and state governments, universities, schools and hospitals. In fact, a report in June 2010 by Lawrence Berkeley National Laboratory and the National ...
