GEOMETRY OF THE BLOCK

• The north block is made slightly concave towards the front. South forms a hybrid convex surface facing the winter sun.

• The point of the south block broadly falls on the surface of large imaginary cones that generated the slightly free geometry & this allow the architecture to break away the grid iron apporach normally associated with solar architecture.

BASIC DESIGN VECTORS

• To integrate functionality of building with energy applications.• To minimize energy demand in the building through architectural intervention. (eg. Passive concepts such as solar radiation, lattice work for shading, insulation and landscaping).• To meet the space conditioning and lighting demands through energy efficient system.• To meet the electric energy demands using renewable energy sources

CLIMATOLOGY

• Building designed as such wind direction can be redirected. • Deciduous trees used in the south to shade the building in summers. • in winters these shed their leaves thus letting in winter sun• Building oriented along east west axis so as to have maximum exposure

along north-south. • South side partially sunk into ground to reduce heat gains and loses.• East and west devoid of opening are shaded

AMMONIA ABSORPTION CHILLERS

• A set of eco-friendly chillers run on LPG and require minimum energy 9kw.

• As LPG is non-renewable sources of energy so efforts are made to run the chillers on producer gas generated by wood burning gasifires.

• For conference hall of 100 people temperature requires less than 25 degree Celsius which can be attained by these chillers.

ROOT ZONE SYSTEM

PHRAGMITES PLANT WATER COLLECTING SYSTEM

• Waste water is recycled by ‘root zone’ technique in which the roots of phragmites plants with special capabilities of collecting the waste at the roots are used to clean the water which is used for irrigation. It cleans 5metre cube of water every day.

• Water harvesting and watershed management are proposed in entire area.

• SOLAR HOT WATER PANELS

RENEWABLE ENERGY SYSTEM

• 24 hot water panel forms a part of parapet walls inclined at 70 degree instead of 45 degree.

• Fulfills the daily requirement of 2000 litres daily at 65 degree celsius.

• In winters gas derived from burning twigs, dry leaves etc. serves as a back up source to heat the water.

BIOMASS GASIFIER SYSTEM

The biomass gasifier is the main source of power during the dayApart from fuelwood, the gasifier can also use straw, small twigs and branches, and other crop residue. To make such fuel easy to handle, it is chopped into small pieces which are pressed together to form compact cakes or briquettes. The 50-kilowatt gasifier runs a generator, whose diesel requirements have been cut down to 30% after appropriate modifications; the rest of the fuel comes from the gasifier in the form of producer gas. One unit of electricity produced needs 1 kg biomass and 90 ml of diesel.

CLIMATOLOGY

Solar water heater taps the suns energy directly, a series of photovoltaic panels capture the energy and store it by charging a bank of batteries. A number of panels, each measuring 1.1 by 1.2 metres, are joined and form an integral part of the roof of the building. The panels can generate up to 10.7 kilowatts peak of energy, which is fed into a 900 ampere-hour/240 volt battery bank. Independent panels power most of the lights located outside the building. Each such light has a pair of small photovoltaic panels (roughly a metre wide and half a metre tall) and is thus a self-sufficient stand-alone unit.The sun is the powering force of RETREAT, where solar panels are used to form a 'solar roof'

Photovoltaic panels also run a water pump
