Need of energy efficient structure

2.  To make the use of any object or material to provide insulation
within the building of any purpose is generally refers to building
insulation.
 Majority of insulation in buildings is for thermal purposes, the term
also applies to acoustic insulation, fire insulation, and impact
insulation (e.g. for vibrations caused by industrial applications).
 To achieve thermal comforts in a building i.e the satisfaction of
mind with the provided thermal environment , thermal insulation
works as an important factor .
 Many forms of thermal insulation also reduce noise and vibration,
both coming from the outside and from other rooms inside a
building, thus producing a more comfortable environment.

3.  When we use insulation in a building :-
 The building is energy-efficient, thus saving the owner
money.
 It provides more uniform temperatures throughout the space.
There is less temperature gradient both vertically (between
ankle height and head height) and horizontally from exterior
walls, ceilings and windows to the interior walls, thus
producing a more comfortable occupant environment when
outside temperatures are extremely cold or hot.
 It has minimal recurring expense. Unlike heating and cooling
equipment, insulation is permanent and does not require
maintenance, upkeep, or adjustment.
 It lowers the carbon footprint of a building.

4.  Interior walls, ceilings and floors where sound control
is desired.
 Exterior walls. Sections sometimes overlooked are
walls between living spaces and unheated garages or
storage rooms, dormer walls, and the portions of
walls above ceilings.
 Basement walls.
 Floors over unheated or open spaces such as over
garages or porches. Floors over unheated basements.
The cantilevered portions of floors.
Insulation—when installed into a home ,
commercial, institutional or industrial building—
provides an environment where you can live and work
comfort.

5. Insulation is one of the most
important, cost-effective, energy
saving building materials in a
home. In fact, without the
insulation, some of the other
energy-efficient components in a
home won’t perform as intended.
Insulation is used as a thermal
and acoustical solution in the
walls, ceilings, floors, and attics of
a home or every part of the
building envelope. Insulation
keeps your home cooler in the
summer and warmer in the winter.
Insulation in a home saves energy
and is perhaps the most cost-
effective way to lower energy bills.

6. Insulation systems are used
extensively in commercial,
institutional and metal buildings
as a solution to reduce the rate of
heat transfer through the roofs
and sidewalls . Board, blanket
and batt insulation also installed
on and within the interior walls,
reduces the transmission of
room-to-room noise. Insulation
is used on chilled water piping,
HVAC duct sand equipment for
thermal, sound, condensation
and process control. Insulating
saves energy and helps reduce
greenhouse gas Emissions.

7. Insulation is used to insulate
HVAC ducts and equipment,
process piping, industrial
equipment, tanks and vessels
found in power plants,
petrochemical plants,
refineries and other industrial
applications. These insulation
systems are carefully specified
to reduce energy costs,
enhance process performance,
reduce greenhouse gas
emissions, protect personnel,
control condensation, reduce
noise levels and to maximize a
return on investment.

8.  Materials that are used in a building
specifically for the reduction of heat
transfer in the building or otherwise
which form the thermal envelop are
building insulation materials.
 The choice of which material or
combination of materials is used
depends on a wide variety of factors.
Some insulation materials have health
risks, some so significant the materials
are no longer allowed to be used but
remain in use in some older buildings
such as asbestos fibers and urea.
 Some of the materials are form (batts,
blankets, loose-fill, spray foam, and
panels), structural contribution
(insulating concrete forms, structured
panels, and straw bales), functional
mode (conductive, radiative,
convective), resistance to heat transfer,
environmental impacts, and more
