What is green building?
The term green refers to environmentally friendly pracces from building design to the landscaping choices.
➢ It also encompasses energy use, water use, and storm water and wastewater re use. Any building ,old or new, can be convert in green by following:-
➢ Reduce energy use.
➢ Improve indoor air quality.
➢ Reduce construcon material waste.
➢ Minimize water usage.
➢ Energy Efficiency
➢ Use of Recycled / recyclable Products
➢ Use of Renewable Energy
➢ Water efficiency
➢Ulmately leads to Sustainable Development
➢reduce carbon consumpon

IMPORTANCE OF GREEN BUILDING
➢Economic Factor : resource efficiency -reducons in operaon costs.
➢Environmental Factor : solar powering - Recycling rainwater – Reusing building materials.
➢Social Benefits: non-toxic, low eming material more comfortable living – working environments.

1.RETREAT: Resource Efficient TERI Retreat for Environmental Awareness and Training ,Gurgaon
GENERAL DESCRIPTION •
RETREAT IS TERI’S VISION REALIZED THE VISION OF BUILDING A SUSTAINALBLE HABITAT,WHICH IS NOT JUST THE FIRST OF ITS KIND IN THIS PART OF THE WORLD,BUT ALSO ONE THAT INSPIRES MANY SUCH HABITATS TO BE CREATED IN FUTURE. • RETREAT IS A PART OF THE 36-HECTARE TERI CAMPUS AT GUAL PAHARI,ABOUT 30KM SOUTH OF DELHI,IN THE NORTHERN STATE OF HARYANA.BUILT AS A MODEL TRAINING COMPLEX,RETREAT DEMON STRATES EFFICIENT UTILIZATION OF ENERGY,SUSTAINABLE AND INTEGRATED USE OF BOTH NATURAL RESOURCES AND CLEAN AND RENEWABLE ENERGY TECNOLOGY ,AND EFFICIENCT WASTE MANAGEMENT. • IT IS A 30 ROOM TRAINING HOSTEL WITH CONFERENCE FACILITIES FOR 100 PEOPLE,DINNING SPACE AND A KITCHEN,RECREATIONAL AREA,COMPUTER ROOM AND A LIBRARY. • TO INTEGRATE THE FUNCTIONALITY OF THE BULDING WITH ENERGY APPLICATIONS • TO MEET THE SPACE CONDITION AND LIGHTINING DEMANDS THROUGH ENERGY EFFICIENT SYSTEM.

DESIGN FEATURES
PASSIVE DESIGN SYSTEM •
VARIOUS PASSIVE DESIGN CONCEPT HAVE RESULT IN A REDUCTION OF SPACE CONDITIONING LOADS BY 10% - 15%.BUILDING ENVELOP EFFICIENCY ,WHICH RESULT IN LOWERING OF SPACES CONDITIONING LOADS,WAS ACHIVED BY ADOPTION OF VARIOUS PASSIVE TECNIQUES.
• THE ROOF IS INSULATED BY USING VERMICULITE CONCRETE AND CHINA MOSAIC WHITE FINISH. WALL ARE INSULATED BY USING EXPAND POLYSTYRENE INSULATION.
• PART OF THE BUILDING IS SUNK INTO THE GROUND IN ORDER TO TAKE ADVANTAGE OF GROUND STORAGE AND THUS STABILIZE INTERNAL TEMPERATURE..
• SHADING DEVICE AND FNESTRATION HAVE BEEN DESIGNED TO CUT OFF SUMMER SUN AND TO LET IN WINTER SUN.
• THE BUILDING IS ORIENTED ALONG THE EAST – WEST AXIS SO AS TO HAVE MAXIMUM EXPOSURE ALONG THE NORTH AND SOUTH.THE NORTH BLOCK IS MADE SLIGHTLY CONCAVE TOWARDS THE FRONT,WHILE SOUTH BLOCK FROM A HYBIRD CONVEX SURFACE OF LARGE IMAGINARY CONES THAT GENERATED THE SLIGHTLY FREE GEOMETRY AND THIS ALLOWS THE ARCHITECTURE TO BREAK AWAY THE GRID IRON APPROACH NORMALLY ASSOCIATE WITH ‘SOLAR ARCHITECTURE’.

ORIENTATION
➢ THE TERI RETREAT BUILDING, GURGAON HAS BEEN SELECTED TO SHOW HOW ORIENTATION ALSO PLAYS AN IMPORTANT ROLE IN “SOLAR ARCHITECTURE”. THE TERI RETREAT BUILDING WAS ORIENTED ALONG THE EAST-WEST AXIS SO AS TO HAVE MAXIMUM EXPOSURE ALONG NORTH AND SOUTH WHICH IS THE MOST RECOMMENDED ORIENTATION IN SOLAR PASSIVE ARCHITECTURE. SOUTH ORIENTATION RECEIVES MAXIMUM SOLAR RADIATION DURING WINTERS WHICH IS PREFERABLE AS COMPOSITE CLIMATE RECEIVES SEVERE WINTERS. THE ORIENTATION ENSURED WINTER SUN (WHILE KEEPING THE SUMMER SUN OUT) AND ADEQUATE DAYLIGHT IN THE BUILDING.

Design features
1. PLANNING TECHNIQUE
Building is largely buried under the ground to use earth masses for natural insulaon.
➢ the roof form creates an efficient surface/ Volume ratio opmizing material quantity.
➢venlang window at upper volume release the accumulaon hot through pressure difference.
➢External wall of the building are nearly a meter deep but have been hollowed out as alcoves to provide storage that becomes an insulaon wall with efficiency of space.

2.CONSTRUCTION TECHNIQUE
➢Locally made clay fuses over the concrete slab to form a non-conductive layer.
➢ clay fuses entrap air known as sandwich vault.
➢China mosaic glazed les enhances insulaon.

3.LIGHTING
➢ indirect lighng , upper level large opening – Facing north .
➢Sky light are inter inside building by projected masses from the roof. Small cut out on roof slab filled with hollow glass block.
➢ Day lighng by north-glazing, skylights, and roof cut-outs.

4. MICROCLIMATE
➢Water channels ,rain water and over flow of pumped water from the roof are harnessed through a series of cascading tanks and water channel to finally culminate in a pond form which it is recycled back or used for irrigang vegetaon
