INTRODUCTION
Bioclimatic Building is the
practice of increasing the efficiency with which buildings and their sites use
and harvest energy, water, and materials, and reducing
building impacts on human health and the environment, through better
sitting, design, construction, operation, maintenance, and
removal — the complete building life cycle.
Green building is also sometimes known as
"sustainable building" or "environmental building“.
OBJECTIVE
To minimize the operating cost by increasing the
productivity and using less Energy and water.
To reduce the environmental impact on the building.
To minimize heat gained in day time and maximize the
heat loss in night time in hot season and reverse in cold season.
To select the site, according to the climatic criteria
& optimize the building structure.
To control solar radiation & regulate air
circulation
TECHNOLOGY FEATURES
Strength is equal to standard 9"(229mm)brick
wall, but consumes 20% less bricks.
The air medium that is created by the bond helps
maintaining a good thermal comfort inside the building.
As the construction is appealing to the eye from both
internally & externally, plastering is not necessary.
100 square feet(9.3 sq.m)of this wall will cost only
Rs.6454/- as against the traditional 9" wall that costs Rs.8759/-.
The overall saving on cost of this wall compared to
the traditional 9" wall is about 26%.
THE ROOFING TECHNOLOGY – 'FILLER SLAB' METHODOLOGY
Consumes less
concrete and steel due to the reduced weight of the slab by the
introduction of a less-heavy, low-cost filler material such as rejected Calicut
tiles, clay pots, broken pieces of cement blocks and brick bats.

PASSIVE HOUSE
PASSIVE HOUSE
Passive house
The term Passive
house (Passivhaus in German) refers to the rigorous, voluntary, passive
house standard for energy use in buildings. It results in ultra low energy
building that requires little energy for space heating.
The Passive house standard requires that the building
is within the following limits:
The building must not use more than (≤) 15 kWh/m²a
(4,755 Btu/ft²/yr) in heating Energy.
The specific heat load for the heating source at design
temperature must be less than 10 W/m²
With the building pressurized to 50Pa by a
blower door, the building must not
leak more air than 0.6 times the house volume per hour (n50 ≤ 0.6/h).
DESIGN AND CONSTRUCTION
Moladi
Moladi
The moladi system constitutes the use of a removable ,
reusable , recyclable and light weight plastic formwork mould, which is filled
with a South African Bureau of standards approved and Agreement certified
aerated mortar to form the wall structure of a house in as little as one day.
Each set of moladi formwork panels can be re-used 50
times making the technology cost effective due to its repetitive application
scheme, reducing the cost of construction and transportation significantly.
The moladi system produces durle and permanent
structures which have been subjected to numerous tests and independent reports.
CONCLUSION
The building constructed using low cost techniques
fulfills the maximum efficiency which traditional building gives.
Not only the aspect of strength and efficiency is
fulfilled both the aesthetic appearance is also done economically.
By the adoption of bio climatic building technique the
healthy environment is provided for human to live safely.
A sustainable environment will be created because of
this bio climatic building.
