Why rooftop greening

• Increase access to private outdoor green space at home • Support urban food production • Promote community • Improve air quality and reduce Co2 emissions • Delay stormwater runoff • Increase habitat for birds • Isulate buildings

Economic benefits


Reduced Renovation Costs

Reduced Energy Costs Offering additional space for leisure activities

Definition Two types of rooftop gardens depending on the structutal design of your roof Extensive rooftop garden (inaccessible) Intensive rooftop garden (accessible)


Extensive rooftop garden


• 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


• 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.

Managing eronsion and controlling sedimentaion • Erosion can be coused by natural events like rain runoff and wind. • It wash away unprotected topsoil and expose less stable layers of

soil below. • It carry the soil to areas where is not desirable (river, streams,

lakes and oceans)


Managing eronsion and controlling sedimentaion The results effects including


• Clogging storm drain systems, potentially resulting in flooding

• Damaging wildlife habitat and plant life in streams and lakes

• Adversely affecting navigation and recreational opportunities in bodies of water like bays and lakes.

• Damaging quality of water needed to support aquatic organisms

A void Managing eronsion


• Temporary seeding are used to propogate plants on a slope . • Hydroseeding is a method that mixes plant seed with a bindinagent that can be

sprayed



• Wattles : a long cylinders made of natural materials such as straw and coconut wrapped in a mesh material. It slow down the flow of water runoff



• Silt fences: made of a geotextile fabric fence generally placed at the toe of a slope



• Mulch: made of chipped wood, bark or haycan be placed on the surface of the groundplaced at the toe of a slope



• Sediment basins: The basin traps water and allows sediment to settle to the bottom.

Effective strategies for stormwater management • Amount of runoff that should be minimized and an acceptable

level of quality should be maintained in the water that does escape the site.


Effective Stormwater


• Basin : Rain water can be channeled in to retention basin.

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.
