Using recyclable natural resources in construction plays a large part in green architecture. But that’s not all. Sustainable architecture also facilitates natural ventilation and lighting and reduces dependency on external resources. For example, one could use green roof systems, which can significantly reduce heating and cooling costs at home.
Green architecture also goes a long way in controlling pollution. Sustainable residential landscapes include the use of planting trees for shade, clean energy resources like solar power, high performance windows “tuned” to the sun, tightly sealed construction, recycling bins, compost, rooftop water catchment systems, avoiding ozone-depleting materials and using salvaged building material.
