Appropriate architectural design
  • Prevailing wind direction was used to orient the openings to have enough draft which aids in cooling the indoors without the use of electrically run fans.
  • Cross ventilation for each room has been appropriately worked with the use of openings.
  • The openings on the western facade of the building has been kept to thinner proportions and lesser numbers-(principal-forced air from outside loses temperature on expansion-thereby allowing the time for cooling of the inside to a lesser extent)
  • Larger opening at the lower floor on the western side, for light penetration with less harsh incident sunlight.
  • Double height spaces were used to allow for air and light movement in the house.
  • Ventilators are provided at the skylights for the free flow of the hot air accumulating below the heated skylight covering.
  • The natural slope on the site was utilized in designing services to minimize labor and cost of trench digging.
  • Existing vegetation on site was respected.

Environmentally sound materials

  • Earth as the primary building material: stabilized rammed earth foundations, compressed stabilized earth blocks for walls, stabilized earth plaster for walls exposed to rain and sun and stabilized earth mortar. Locally available stone has been used for the foundations and a few walls to accentuate for architectural purposes.
  • Insitu-jack arch panel roofing elements to reduce on steel and cement consumption: roofing channels, precast sills, hourdi block (Hollow blocks) to reduce solid concrete and acts as a heat insulator- the heat transferred into the indoors is reduced by 4deg with this kind of roofing system.
  • Employing the local skilled labor for doors, windows and other finishes over buying readymade items with high embodied energy.
  • The wood used for doors and windows is Indian Honne (Pterocarpus marsupium-Indian Kino tree).
  • As the site was lower, the filling was done with the waste building material generated at the site and also the waste generated from other sites was brought in to make the earth fill.
  • As the earth fill had cement waste generated, lime was added locally to neutralize the acidic nature in the soil filled up. Thus increasing the effectiveness of the soil for plant growth.

Renewable energy sources

  • Solar water heater has been used to meet the hot water requirement. There are no electric geysers. Solar lanterns and lights are used in place of UPS during power shutdown. Design is in place to implement the solar PV system for the lighting requirement.
  • Skylight openings provided so that the maximum utility of light is made and enough light is provided for the interiors during daytime. No light is switched on from 6AM to 6PM
  • All rooms are fitted with CFL bulbs.

Power consumption in units from the grid in 2011

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
178 169 210 192 186 176 197 174 201 192 170 185


Water management

  • This house conserves the water that falls on its 1450 sqft roof for all its needs. The grey water from washing machine is recycled for use in toilet of the ground floor. 60 % of the yearly total water consumption is met by rainwater harvesting. The kitchen water is collected and made use for the kitchen garden, thus overall reducing the foot-print of water used by this building to a minimum.

Corporation water consumption in liters in 2011

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
19000 21000 20000 12000 10000 18000 22000 7000 11000 8000 22000 30000

Average corporation water consumed per month in liters in 2011 = 16,666 for a family of 4.

Earth management

  • Plastic and other waste materials were used to fill up the foundation.
  • More than 60% of the plot is set aside for garden which has 16 Ashoka, 2 Badam, 1 Neem, 1 Coconut, 1 Mango, 1 Chikku, 1 Drum stick, 6 Golden Melaleuca, 8 bamboo, 6 Papaya, 2 Karipatta, 1 Gauva, 4 Hibiscus, 1 Sampige tree and small patch of lawn
  • Wet garbage (kitchen waste) is used for preparing compost.
  • Car is washed using rainwater. Keep it outside when it is raining and then wipe it off.
  • Cloth bags are being used for shopping household items for last 6 years.(reuse)
  • Bamboo plants grown in the garden to be recycled for making furniture.
 
 
 
We, in this project have tried to design a sustainable building, which also looks beautiful. Mud has always been a symbol of the rural face. In context with the urban scenario, the use of mud blocks, minimum plastering and extensive use of the ecological construction material has been exhibited in the Kanavi residence in Bangalore. The finishing of the mud blocks has been kept minimalistic with no plaster on the walls. The usage of paint based works has been reduced to a bare necessity, eg-metal grills. The roof uses the in-situ jack arch, and hollow-block (Hourdi block) roofing to reduce the temperature, terracota flooring tiles.
 
 
 
Actual Energy Performance Index in Average units consumed per month in 2011 is 185 units
Percentage of A/C and non A/C regularly occupied spaces: Air conditioners are not used in this residence.
Owner / User Testimony: We moved into this house in May 2006. Completely satisfied with various 'environment friendly' features that have been considered while designing and constructing this house. I am proud to say that house has helped in me and my family in reducing our carbon footprint and in turn has minimised our contribution towards global warming.
