Overview T h e U S G B C ’ s L E E D
• USGBC, Founded in 1998, is to transform the way buildings and communities designed, built, operated.
• To foster an environmentally and socially responsible, healthy and good environment to improves the quality of life.
• A nonprofit organization committed to sustainable building practices.
• USGBC’s member include more than 15,500 organizations that are working to advance structures for healthy places for human to live and work.
• Member businesses : Building Owners and end-users ; architect; government agencies; nonprofits …

Global environmental change S t e p 1 : C h a p t e r 1 - 4 : I n t r o d u c t i o n t o G r e e n B u i l d i n g
Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level.

Extensive rooftop garden
Reducing Heat Is land S t e p 2 : C h a p t e r 5 - 6 : S u s t a i n a b l e S i t e s
• Generally lightweight gardens • Require little or no maintenance • Vegetation covers the entire roof. • Can be installed on both flat and sloped roofs • Depending on climate and the amount of rainfall, can grow a variety of
hardy grasses, wildflowers, mosses and sedums. • not generally walked upon
Intensive rooftop garden
Reducing Heat Is land S t e p 2 : C h a p t e r 5 - 6 : S u s t a i n a b l e S i t e s
• Allow for a more diverse plant selection (perennial flowers, trees) • Generally installed on flat roofs with the vegetation either covering the
entire area or in containers and raised beds. • A stronger roof structure is required (weight of people accessing and
higher soil and container weights, decking and trees ) • More maintenance is required because of the greater variety of plants. • Other considerations for an intensive rooftop garden include condition of
roof, structural and weight capacity, access, cost, irrigation, and drainage.

Chapter 7 : Water Use Ef f ic iency • Water-Efficient Buildings • Recycling wastewater
Water-Efficient Buildings Reducing the amount of water used • Low-flow plumbing fixtures use less water for wash basins, toilets and
showers. • Dual-flush toilets allow the use to select a smaller flush • Waterless urinals use a chemical that is lighter than urine that “pushes”
the liquid waste into the drain without using water. • Composting toilets covert human waste into an organic compost.

Recycling wastewater Reducing the amount of water used • Rainwater runoff can be captured with site features for reuse. • Grey water must be processed before resusing. Using natural
treatment such as live plants, microorganisms and bacteria to clean the water. Lately, it reuse of processed greywater for building uses such as flushing toilets.

A zero energy building (ZEB) or
net zero energy building
is a general term applied to buildings with a net
energy consumption of zero over a typical year
Definition
A zero energy building is a building that consumes
as much energy as it produces…
Why are we Designing and Building ZEB?
1. Building and Construction sector represents is a major
consumer of energy and resources in most cities and countries.
2. Once procured and delivered, a building continues to consume
energy resources for many years. Hence it is important to implement
the right standards and technologies urgently.
3. A ZEB provides a show case of what is doable and what is not.
It helps the industry to identify the appropriate technologies and
serves to build capacity.
