7. WHY D O WE NEED GREEN BUILDINGS ? 7 Green buildings are designed in such a way to reduce overall impact on e n v i r o n m e n t a n d h um a n h e a l t h by: R e duci n g t r a s h , p o ll u t i on and degra da t i o n of e n v i r o n me n t . Efficiently using energy, water and other resources. Protecting occupant health and improving productivity.

Some of the more common green construction practices include: 8 Using sustainable building materials like recycled glass and steel, as well as r e n e w a b l e ma t e r i a l s l i ke b a mboo a n d ru b b e r I n s t a ll i n g e n e rg y - e ff i c i e n t w i n d o w s a n d do o rs Using lower-VOC (volatile organic compounds) paints and stains Constructing green roof systems (aka “plants on your roof”) that offer many benefits, including on-site gardens, rainwater management, and pr o t e c t i n g y o ur ro o f fr o m t h e e ff e c t s of h a rmful U V l i g h t Adding water harvesting and purification systems that don’t just manage, b u t a l s o ma k e t h e most use of r a i n f a l l Maximizing natural light, which cannot only save on lighting requirements (and subsequently energy costs), but also help keep buildings warm in colder months Using renewable energy to power the building—for example, installing a commer c i a l s o l a r p a n e l s y s t e m

26. STORMWATER DESIGN HEA T ISLAND EFFECT The elevated temperature in urban areas as compared to rural, less developed areas is referred to as the urban heat island effect. As cities grow and develop, more buildings and people are added. The process of urban development leads to this phenomenon.
