developing states: scope for technology cooperation with India”
22-25 August, 2005
Challenges in small island
Dependence on fossil fuels for energy production.
Limited Natural fresh water resources
Recycling of materials - Disposal & Reuse
Impact of buildings on the
Consumers of electricity produced from fossil fuels.
GHG emissions contribute to climate change and acid
Depletes land and natural resources
Generate waste which causes land, air and water
- site selection
- urban design
- landscape planning
- CO2 emissions - energy performance
- acid rain - renewable energy
- ozone depletion - water conservation
- rainforest depletion
Criteria & - material selection
- environmental policy Factors - recycling of materials
- transport strategy - waste management
- building maintenance - disposal & reuse
- air quality
- thermal comfort
- lighting & noise
- hazardous materials
Site selection and sustainable site
Site selection and development of site infrastructure to reduce
vehicular transportation and easy access to daily facilities. Site
layout with respect to wind direction and sun path.
Appropriate erosion control mechanisms, top soil preservation,
prevent run- off from site & prevent heat island effect.
Reduce site disruption by appropriate planning, preservation of
natural vegetation, appropriate landscaping.
Energy efficient lighting on site including the use of renewable
energy sources for external lighting.
Teri campus at Gual pahari, a unique
experience in sustainable and energy
efficient building design…
Minimal depletion of plant cover
Efficient infrastructure planning
Minimise transportation lengths
Untouched natural habitats
Energy efficient site lighting, solar energy based campus lighting.
Site specific guidelines for eco-
housing, Sri Lanka
Reduction in energy demand
Use of solar passive strategies, use of on site sources
Maximise system efficiency
Use of renewable forms of energy.
RETREAT Building, Gual Pahari, off the grid…. i.e. energy
efficient building drawing power from renewables.
Enhance system efficiency and
maximise use of renewable forms of
Use of energy efficient lighting and control devices.
Use of low energy space conditioning systems.
Use of renewable forms of energy e.g. wind, biomass, solar for
thermal application and electricity generation.

water heating system,
Building material selection
Maximize the use of regional/locally manufactured
Best fit options as per the climate suitability and specific
construction requirements for that particular region
Allow significant reduction in transportation (with delivery
radius <100 kms) contribute to low embodied energy
consumption and life cycle costs
Materials with reusable & recyclable potential/Use
industrial by products
Use materials, which are manufactured from waste or
recycled materials, products which can be reused
Water quality standards and treatment required.
Reduction of water use by efficient fixtures and fittings.
Reduce landscape water requirement by using indigenous
species, enhancing irrigation efficiencies, restricting water
consuming landscaping e.g. lawns.
Waste water treatment/recycling/reuse
Rain water harvesting for storage/recharge
Appropriate waste segregation and collection
Identify facilities for recycling of non biodegradable wastes such as
plastics, glass and paper
Develop decentralised treatment systems based on composting or
anaerobic digestion process for segregated organic waste at the
Identify appropriate options for use of by products – biogas and
manure from treated organic waste
Develop norms for use of by products based on local standards
Develop norms for disposal of non degradable and inert waste in
landfills based on local standards to ensure safe environment in
the surrounding areas
Green building solutions are economically viable with
minimal environmental footprint which can bring about
30-40% energy savings in new buildings and 20%
savings in existing buildings
with reduction in…...
demand on the fossil fuels
pressure on natural resources e.g. water.
