I started my career in alternative energy and energy conservation, what is now Green Design, Sustainable Design Green Architecture, Eco - Architecture and just plain saving energy!
When the world dropped the energy ball and I spent the years since just plain saving and rehabilitating buildings. There is no way to make a building Greener than by saving it from decay and demolition.
Just so happens my sojourn into rehabilitation overlapped with my prior work saving energy - moisture control. Rain, water vapor from a shower, humidity on hot summer day, wind driven air infiltration, and the roofing, siding, sealants, and membranes that control them are critical to the longevity of a building also directly and substantially dictate it's energy use!
Now the cycle of life has turned and solar energy in all it's forms, photovoltaic’s, wind generators, co-generation, conservation, super - insulation, recycling, re-use, life cycle costing, daylight, embedded energy, embedded carbon, carbon credits, water retainage, grey water recycling, VOC's, and indoor air quality are just all part of Green Design!
