Abstract: Energy saving or energy efficiency in buildings is a
method to design buildings by taking the advantage of natural
resources and innovative use of passive solar techniques. Mainly
these buildings have high performing controlled ventilation, high
efficient heating, lighting and cooling system, high performing
building envelop, than a traditional or average contemporary
building. Energy efficient buildings are designed to provide a
significantly higher standard of energy efficiency than the
minimum required by the national building standards.
The prime objective of writing this paper is to increasing the
energy efficient building designs which can make a small
contribution to reducing energy demand and carbon emissions.
Aims also to help to determine the effective low-cost, low
maintenance energy efficient designed strategies for the better
sustainable architecture. These strategies can be used as
guidelines by the Architects to improve design practice because
our quality of life and society is linked to the environment.
To understand the energy efficient buildings the case taken into
consideration is a SOS Tibetan Children’s Village, Rajpur,
Dehradun. The SOS is best example of implementation of energy
efficiency building systems, it is built by taking advantages of
climatic conditions of a region, simple construction techniques ,
innovative use of passive solar techniques , appropriate material
selection and intelligent landscape planning .
These kinds of studies helps to minimize energy consumption and
can be used effectively to produce good architecture which is
traditional, low cost as well as eco friendly by taking the
advantage of climatic conditions of a Particular region. The SOS
Tibetan Children’s Village is an appropriate example to explain
energy efficiency in building designs. The analysis will help in
catering the demand of energy efficient building, which can be a
measure to overcome the dependency on mechanical systems.
Keywords: Passive solar techniques, building envelop, eco
friendly, national building standards, innovative.
1. INTRODUCTION
Now- a -day’s energy saving buildings, zero energy buildings, green or sustainable architecture is in demand. The reason for this demand is shelter. Shelter is one of the basic needs of human beings. On one hand shelter provides facilities for human activities and social development on other hand its impact on the environment is very serious. If the buildings are
not designed keeping energy efficiency in mindby Architectsa lot of natural resources can go in vain because demand of buildings increasing day by day and Architect plays major role in design of buildings.Modern buildings which are designed today haveserious environment effect. These buildings are built using many industry made common building materials such as bricks, cement, and concrete, steel, plastic and glass etc.creates dangerous environmental problems increase carbon monoxide in atmosphere ,greenhouse gas emission, global warming , acid rain, ozone layer depletion, shortage of clean water, toxic waste and increasing pollution is directly or indirectly creates health problems.
Therefore the building which is less dependent on energy for their successful operationto overcome dependence on mechanical system ; the answer comes directly in mind is energy saving buildings.The energy efficient building managesheating, lighting and cooling effect without compromising comfort or quality of life.
2. STRATEGIES TO REDUCE ENERGY
An architect can achieve energy efficiency in the building by applying architecture related to nature or bioclimatic architecture and taking advantage of the local climatic conditions. Some common design strategies or elements directly or indirectly reduce energy use in buildings. Following are the common ways by which energy can be reduced in building design:
• Landscaping
• Ratio of built and open spaces
• Orientation
• Location of water bodies
• Building envelop
• Controlled ventilation
• Energy efficient doors and windows
• High efficiency heating and cooling system
• Pitched roofs

4. INTRODUCTIONABOUT SOS CHILDREN'S
VILLAGE, DEHRADUN
The SOS Tibetan Children's Village, Dehradun is located in the small town of Rajpur in Mussoorie foothills;Dehradun Uttarakhand is one of the best examples of energy savibuilding in India. The site of SOS measures 14,300 sq.m. And comprising of 15 family cottages, small nursery school, dispensary, community house, residences for the director and co-workers, recreation room and place of worship was inaugurated on 4th of October, 1999. The Central Tibetan Administration aims to build it to protect and promote Tibetan culture. The SOS Tibetan Children's Village Dehradun dedicated to the Tibetan children that provide home and education to 225 children.
The site has a slope towards south, which allows orientation of the cottages. The site comprises of horticulture zone, animal husbandry, and floriculture and crop cultivation with the natural endowment of slopes and the watercourse.
The site has the entrances from the north Mussoorie – Dehradun 30’ wide steep road.

12. CONCLUSION
In the end, while design, type, cost, uses and style differs but the energy efficient buildings have some common ways which can be used in any type of building .Increasing windows or openings area as per the climate and the solar path (Preferably openings towards the south) of the region. Properly designed overhangs over the openings will help to prevent overheating in summer. Energy efficient buildings provide comfort, lowers operating costs last but not the least most importantsave our valuable environment.
