Total Cost of Dwelling Units :
A. Sustainable affordable housing project
The aim for sustainability lies in adopting materials & technologies that reduce the cost of time frame
construction, and that cover environmental protection and energy conservation.
No heavy equipment or sophisticated T&P required = Saves energy & fuel
Less consumption of cement, Steel & aggregate = Saves energy
No shuttering = Saves forest
Flyash mixed in C.M = Saves cement & energy
Perforated bricks = Better insulation
Ceiling & walls, white finish = Improve day light
No external paint or plaster = Less maintenance
Controlled quality concrete (due to pre-casting) = Less maintenance
Precast Ferrocement elements = Less maintenance
Less weight of structure = Safer in EQ
All pre-casting at site = Saves transportation and fuel
B. Savings in Embodied Energy
No shuttering used - Saves wood & steel
30 % reduction in consumption of cement – Saves embodied energy
60 % reduction in steel reinforcement (less than 1 kg/ sft. in comparison to 3.5 kg/sft)
in conventional construction - Saves embodied energy
Perforated hollow Bricks - Saves fuel & enhanced Insulation

C. Seismic Resistance
The houses have been designed as per IS : 4326
with
Load bearing walls concept with box behavior
which has lateral stiffness much higher than
framed structure
Vertical reinforcement at T & L junctions
Vertical reinforcement around openings
Plinth band, lintel band & roof band
Building Form - Rectangular, therefore more
stable
Building configuration is symmetrical w.r.t mass
and rigidity
Structure is light due to 15 % less thickness of
walls, 30 % reduction in concrete slab and use of
ferrocement thin elements.
D. Saving in Water Consumption (Water Conservation)
Less water consumption during construction:- due to
lesser volume of masonry, less volume of concrete, due
to no ceiling plaster, due to no external plaster.
The precast slab panels, stairs, sunshades, shelves etc.
cured with spray of water. There is no free flow of
water, thus conservation of water during construction
The precast elements covered with thick cloth / gunny
bags and then water sprayed on them. This avoids water
rebound and ensures sustained and complete curing;
conserving water.
Water ponding done in sunken portion of WC/ Bath
and then ponding used for curing. This conserved water
and avoids water flowing away.
The mechanized bricks have high compressive strength
and low water absorption –thus saves water.
Ferrocement elements also being thin elements –
consume less water.
Hardy plants species used in Horticulture which require
less water.
Soft permeable pathways to reduce run off rain water
Ground water recharging through Rain Water Harvesting
wells.
