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.

Water run-off

Managing eronsion and controlling sedimentation
Storm water management
Water runoff
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)
Water runoff
Managing eronsion and controlling sedimentaion
The results effects including

Clogging storm drain systems,
potentially resulting in flooding
Damaging wildlife habitat and

Adversely affecting

Damaging quality of water

Water runoff
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

Water runoff
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

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

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

Water runoff
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.

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.

PV provides for the entire
electrical system as well as for the
buildings. For example, PV on
buildings enhances urban energy
reliability. Heres how.

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.
