      Sustainable building
    "A sustainable building is
    one which
‡    uses less water,
‡   optimises energy
    efficiency,
‡   conserves natural
    resources,
‡   generates less waste
‡    provides healthier spaces
    for occupants,
    as compared to a
    conventional building."
                buildings?
Why sustainable buildings?
    The main reason why we need sustainable
    buildings are because buildings effect to:

‡    Raw material consumption              30%
‡    Energy consumption                    42%
‡    Water consumption                     25%
‡    Land consumption                      12%
‡    Atmospheric emissions                  40%
‡    Water effluents                        20%
‡    Solid wastes                           25%
‡    Other releases                        13%
    Sustainable building design
Main      strategies
y   Passive and Active solar design
y   Building Insulation
y   Water management
y   Natural ventilation
y   Lighting and heating
y   Building material
y   Waste management
y   Indoor air quality
Passive and Active solar design
                     ‡   Passive solar design
                         refers to the use of the
                         sun's energy for the
                         heating and cooling of
                         living spaces.

                     ‡   Active solar design
                         refers to the use of
                         active mechanical
                         devices like PV panels
                         and rooftop solar water
                         heaters to capture sun·s
                         energy in the buildings.
Building insulation
             ‡ Insulate walls ceilings
             and floors
             appropriately.
             ‡ Consider slab
             insulation in colder
             climates.
             ‡ Provide insulation to
             exterior elements
             which are
             thermallymassive.
Water management
‡   Toilets ² low flush cistern
    displacement
‡   Waterless ² composting,
    incineration
‡   Urinals ² waterless
‡   Wash hand basins ² push taps, flow
    control
‡   Water control in gardens, using
    grey water
‡   Construct rain gardens.

 Rain Catchment     Greywater Systems
Natural Ventilation
                  Operable windows pull
                  fresh air into one side of
                  the       room,      while
                  ventilation stacks pull the
                  air out on the opposite
                  side of the room
                  At extreme temperatures,
                  automatic          backup
                  mechanical      ventilation
                  systems used
Overhangs                 Natural day-lighting and
                          heating




Overhangs, cantilevers,     Daylight reduces the need for electrical
vegetation windows in       light sources, cutting down on electricity
summer.                     and associated pollution and costs

Waste management
       y    ew Markets for Recycled Building Materials
              y   New sustainable Building Practices
‡    expand markets for products containing recycled content
    such as outdoor benches, toilet partitions and shelving made
    from plastics;
‡   flooring products made from recycled rubber;
‡   gypsum wallboard made from discarded wallboard materials;
    and
‡   recycled nylon materials spun into new carpet
    It takes up to 20,000 years for synthetic materials in carpet
                      to fully degrade in landfills
 Sustainable Building Practices
Requires materials to be
separated and recycled to reduce
burden on community landfill
facilities
   ‡Extends life of landfills
   ‡Prevents potential
   contaminants from reaching
   groundwater supplies
   ‡Reduces need to use virgin
   raw materials
  95% of construction waste is
           recyclable
Indoor Environment Quality
‡Daylight and Access to Views
‡Shades / blinds to control
glare
‡Low VOC everything
‡Carpets, paints, adhesives,
sealants, composite wood
products
‡Indoor plants
‡Acoustics
RETREAT
RETREAT- is a part of TERI·s Gual Pahari campus, about 30 km
south of Delhi, in the northern state of Haryana.
‡ self-sufficient, and independent of any external power supply.
‡ The complex saves 40%-50% of energy costs over conventionally
designed buildings at an additional
 investment of about 25%.

Approach
‡Solar water heaters
‡Photovoltaic panels
‡Gasifier
‡Energy-efficient

Benefits of sustainable buildings
‡   Tangible benefits            ‡   Intangible benefits
                                 ‡   Enhanced air quality,
‡   Energy savings : 20 - 30 %
                                 ‡   Excellent day lighting,
‡   Water savings : 30 - 50%         Health & wellbeing of the
                                     occupants,


                                 ‡   Conservation of scarce
                                     national resources
Conclusion:
 A sustainable home conveys a sense
 of well being. This feeling of home
 assists us in creating a sustainable
 lifestyle that allows us to nurture the
 home and it`s surrounding gardens
 and grounds, thereby lessening our
 impact on the earth.
