Composite climate and aurabindo ashramam,new delhi
DESIGN CONSIDERATION FOR COMPOSITE
Regions having a composite climate display characteristics of hot and dry,
warm and humid as well as cold climates.
•As the winters in this region are uncomfortably cold, windows should be
designed such that they encourage direct gain of solar heat during this
•Deciduous trees can be used to shade the building during summer and
admit sunlight during winter.
•Well-insulated and very thick walls give a good thermal performance if the
glazing is kept to a minimum and windows are well shaded.
•In case of non-conditioned buildings, a combination of insulated walls and
high percentage of glazing will lead to very uncomfortable indoor conditions.
•Indoor plants can be provided near the window, as they help in evaporative
cooling and in absorbing solar radiation.
•Evaporative cooling and earth air pipe systems can be used effectively in
•Desert coolers are extensively used in this climate, and if properly sized,
they can help in achieving comfort levels.
DESIGN FEATURES (TAKEN FROM SOLAR
ENERGY CENTRE,GAUL PAHRI, GURGOAN)
The Aurobindo Ashram Trust (Delhi branch) is a charitable society doing pioneering work in
various fields, notably education, philosophy, and culture.
The building complex was planned in the form of offices, swimming pool, library, dining,
meditation, and residential facilities. it is planned to house students, visitors, and ashramites - in a
hostel-like block which are laidout around 3 hexagonal courtyards
The building as it grows will enclose one large courtyard around which there will be 12 such
small duodecagonal blocks.
The planning grid is a space-filling grid composed of squares and equilateral triangles. The
courtyards are surrounded by overlooking corridors, around which the square grids are divided
into two rooms and the triangles divided into two sets of toilets and dressing areas.

RAINWATER AVAILABLE FOR HARVESTING
Total area: 95, 870 square metres (Sq m)
Average annual rainfall in Delhi: 611 millimetre (mm)
Total volume of water harvested: 16, 366 cubic metre (m³) or 1,63,65,879 litres
This represents 43 per cent of the total rainwater harvesting potential.
RAINWATER HARVESTING SYSTEM
In this campus the rainwater from various
catchments, including rooftop, surface
runoff from open areas, is harvested.
ROOF TOP RAIN WATER HARVESTING
The rooftop rainwater from this
building is collected through a network
of pipes and chambers and diverted to
the dry open well of 15 m depth and
2m in dia. The rooftop rainwater passes
through a desilting chamber before it is
diverted to the recharge well.
WATER SUPPLY SOURCE
The water requirement is met through
three tubewells and is supplemented by
Municipal water supply.
The plan of the hostel is duodecagonal
in shape centred around hexgonal
courtyards.the courtyards along with
carefully designed ventilators and
windows aid in cross ventilation
Light-coloured permanent finished walls
have high emissivity and poor
absorbitivity.deep recessed windows
reduce solar gain
•Rough white finish on the building exterior for high emissivity and poor absorptivity.
•Deep recessed window offset the negative effects of rooms that are not oriented as per solar
•Properly designed windows and ventilators and interconnected courtyards aid in cross-
•Dense vegetation modifies ambient conditions
•Window design encourages only use of daylighting in the rooms during daytime
•Building integrated solar water heating systems
Load-bearing structure reduces embodied energy by reduced consumption of concrete
Except on ground floor, each room gets a balcony on the outer faces.

Parapet wall with integrated solar hot
water panels.also seen is the sructure,
which houses the hot water tank
