Green Buildings Sustainable Design

As awareness about sustainable development is growing, changes are evident in the field of infrastructural development. This is where the concept of ”green buildings” comes in.

SUSTAINABLE DEVELOPMENT – It means that we should utilise natural resources in such a way that our needs are fulfilled today but there is enough left for the future generations as well. If trees are being cut in the name of setting up an industry, equal number or more trees should be planted elsewhere to compensate nature for this loss. Only then can we create a balance between infrastructural development and natural conservation. Agenda 21 is a United Nations program related to sustainable development in 21st century.

WHAT ARE GREEN BUILDINGS – Green buildings are environment friendly, durable, comfortable and economical buildings constructed using natural and renewable resources such as wood, bamboo, granite, porcelain and soil etc. The windows are designed in such a way that sunlight naturally lights up the rooms. Use of solar energy, packed gravel or permeable concrete, non-toxic building materials, proper ventilation system, waste reduction save costs and increase safety.

GREEN BUILDING RATING SYSTEMS – Rating systems assist consumers to gauge the level of success as far as construction of green buildings is concerned. These include LEED(U.S. and Canada), CASBEE(Japan), DGNB(Germany), BREEAM(U.K.) etc. Life Cycle Assessment (LCA) evaluates the impact any building will have on environment, economy and society in general by studying various life cycle stages like designing, use of raw materials, construction, disposal, recycling etc.

Benefits of Green Buildings Services:

•    Green buildings reduce energy consumption as they are built of wood rather than brick, steel or concrete. Solar water heating and extra insulation in walls, floors and ceilings is done for this purpose.
•    Due consideration is given to conservation of water. For instance, ‘grey water’ (water from sinks, kitchens but not including human waste) is utilized for maintaining the garden.
•    Renewable materials like wood, baked earth and granite etc. used as building materials are non-toxic.
•    Locally available building materials are preferred which save transportation costs, minimize noise and dust thereby making construction of such buildings economical.
•    Indoor environmental quality (IEQ), indoor air quality (IAQ), light and thermal quality, general well-being of the occupants is enhanced. Good ventilation controls growth of bacteria, dust mites and viruses ensuring good health.
•    Compost bins give natural fertilizers, utilization of ”grey water” minimizes the amount of waste generated and use of rain water collectors promotes conservation.

The success of ”green buildings” or ”natural buildings” rests on simplicity, use of renewable resources and energy efficient designing. The end result is good health, sustainable development and conservation of nature. True to its name, green buildings are another name for environment friendly buildings.
