How to make buildings energy efficient

Why it is necessary to make energy efficient
buildings ?

• Everyone is concerned about environment , and
  doing random activity to save environment. But
  everything starts from home. If we can make our
  building more energy efficient then that will be
  a good contribution to our environment.
• Necessity of making buildings energy efficient-
• To reduce Carbon dioxide release
• To reduce green house gas release
• Optimum utilization natural resources
• sustainable environment
• making our future more healthier
• decresing electricity consumption

The main energy consumption parts in a home are
heating, ventilation, air conditioning.If these
can be controlled in a proper way then energy of
the building can be saved. Energy efficient
building construction consists of two parts. One
is during construction and another is after
construction.If this will be done before
construction then it is better as the post
construction part requires less effort.

Steps For Making energy efficient building during
Construction-
5
Wall Construction-

• Wall is the part of house which contains most of
  the area of house which is exposed to outside
  environment.
• Through the wall most of the heat transmission or
  energy transmission occurs.
• So while constructing building if we are using
  material which are thermal resistant or heat
  resistant then that will be like a bonus point
  especially like a hot country India.
• There are many bricks available in market which
  are heat resistant having a no of benefits.
• Such as porotherm brick, AAC blocks.

6
AAC blocks-

• AAC blocks are autoclaved aerated blocks, which
  are lighter than normal bricks, It makes the
  building temperature less than outside , which
  ultimately reduces the A/C cost by 30.
• They are also sound proof.
• They are best in class fire rating of 4 hours.

7
Insulating Concrete forms-

• Insulating concrete forms (ICFs) are proprietary
  modular units in the form of interlocking blocks
  or panels, made from polystyrene or polyurethane
  foam and filled with concrete.
• Insulated Concrete Form walls act as a thermal
  barrier, making it possible for buildings and
  homes to retain heat more effectively.

8
Porotherm Bricks-

• Porotherm bricks are perforated clay bricks.
• They are very good energy efficient material for
  building construction.
• Perforation of the bricks create a walling system
  which facilitates thermal insulation making the
  rooms warm in winter and cold in summer.

9
Floor Construction-

• Floors are directly in contact with soil and
  human being.
• So energy is always transferred from soil to
  human being .
• The energy depends upon the soil of the area.
• So flooring has also role to make home energy
  efficient.
• Ceramic tiles, vitrified tiles, cement flooring
  are good for homes as they are not very cold to
  feet ,but keeps cool the floors in summer.

10
Roof insulation

• Roof is also mostly exposed to sun, making the
  rooms hot or cold, which ultimately lead to use
  of electronic devices. So if the roofs are
  insulated then it can save the energy of the
  house. There are different type of Insulating
  materials are available which can be used to make
  the roof insulated.
• Slab or block insulation-
• The blocks are made of mineral wool, cork
  board, cellular glass, and cellular rubber or saw
  dust etc.
• Blanket insulation-
• Blanket insulation materials are available
  in blanket shape or like paper rolls which are
  directly spread over the wall or ceilings.
• Insulating Boards-
• Insulating boards are made from pulp of
  wood, cane or other materials.

Doors and Windows-
Doors and Windows are the path through which most
the energy exchange occurs between the
environment and house. What ever the rooms
temperature i.e mostly affected by the air , heat
and cold transmitted through the doors and
windows. There are different type of doors are
available in market which can act as thermally
insulated barrier between the environment and
house. Such as wooden , fiberglass, UPVC material
. But among them fiberglass doors and windows
have excellent thermal property. It is better to
use these kind of doors to make the house more
comfortable energy efficient. Also there are
doors available of mixed category. Such as
wood-clad steel doors, which is better even than
fiberglass materials.

Ventilating system-
Ventilating system also plays a vital role in
maintaining the rooms temperature. In different
season the air passes through in different
direction which affects the rooms temperature by
flowing the air into the house. So consult with
an architecture to make the house s ventilation
system in such a way that the rooms temperature
will be maintained in all season.

Energy saving after construction
16
Rain water harvesting-
Rain water harvesting is common to every one in
their thought of mind, but no one wants to
install in their home. But it is necessary to
have the rain water harvesting system in your
home. Scientists are saying that usable water
will not available after some years which can be
seen that as many areas in India already facing
the problem. What if we have large rooms but we
dont have water to use in future. So it is
better to have a rain water harvesting system
which will make your house more energy efficient.
17
Solar panels-
Solar panels are not new to the world but still
people keep away them from using it. Because they
thought it as a expense and they are saving their
house energy by efficient use of electrical
system But thats not true. Solar panels are one
time expense which makes your house energy
efficient by reducing your electricity
consumption from govt. Source using natural
source of electricity.
18
Buying energy efficient equipment-
Above all we have discussed about indirect way of
saving energy, But the direct way of making house
energy efficient is using energy efficient
equipment which saves a lot of energy. There are
many options available in market which you can
choose according to your budget. But try to not
use old equipment which may cause more energy
consumption.
19
Colour on Walls-
Like every aspect in house colour of room also
affect the rooms temperature. So dont think to
choose random colors for your house that can
affect your houses environment . According to
research dark colors absorb more heat from suns
radiation and then transfers it into the house.
But light colour radiate the heat away from home
making the house more cooler. Example white wall
gains 35 less heat than dark walls. There is a
large range of light colour such as light pink,
light yellow, light green, light blue, light
orange. But many people now a days find the dark
colour more fascinating . Its ok to use dark
colour inside the home but try to use lighter
colour outside the home.

Use of plants
Plant are good to have for cooling effect. Try to
use plant which can cool down your buildings
temperature. For Example Ficus tree, Areca Palm
tree, Aloe vera,bamboo trees, deciduous plants
can keep your plant more cooler.
