Sustainable building designers are usually very familiar wth the local region where they live and can give insight into the best way to build to suit both criteria like geography, weather conditions, lifestyle and landscape. Building designers may differ in their approach from region to region depending on the same criteria. A Queensland building designer for example will carefully consider weather factors that can seriously affect a site including sunshine, wind, rainfall, water catchment and storage, water run-off, humidity, cooling, and other issues.
