edward mazria, an architect out of new mexico, has been making news recently with arcitecture 2030. after spending more than a year researching the subject, back in 2003 mazria declared that, “architecture was the leading cause of climate change.” more than suvs, deforestation, industry, and the burning of fossil fuels, the carbon released in the construction, heating, and cooling of buildings by far surpasses all other sources. in fact, in 2004 residential and commercial buildings alone accounted for 34% of green house gasses being released into the atmosphere. A stagering 72% of green house gasses produced in buildings is a product of lighting, heating, and cooling. these numbers only hammer home the need for design emphasis to be on sustainable energy, passive heating and cooling systems, and proper use of daylighting and natural ventilation. regardless, mazria has been championing something called the 2030 challenge. this challenge is an effort get new buildings to be carbon neutral by 2030. mazria proposes a number of benchmarks to chart progress on the way towards 2030 but his point is clear: reverse the irresponsible design and construction patterns now.
