Earth is home to more than 775.28 crores (more than 7.75 Billion) people, and populations continue to grow. Many specialists worry that the use of natural sources is too unexpected to be sustained. Supplies of energy resources and water are especially threatened. Moreover, we are using these resources in ways that pollute and otherwise harm the earth. Supplies of energy resources and water are especially threatened. Moreover, we are using these resources in ways that pollute and otherwise harm the earth.
A green building, built on principles of ecological sustainability, is one that uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building.
GREEN BUILDING FOCUS ON:
1. Efficient utilisation of resources - water, energy and construction materials;
2. Protection of occupant health (improved air quality) and enhancement of employee productivity (Better use of daylight and natural ventilation).
3. Reducing pollution, waste and environmental délabrement as compared to conventional buildings. Prominence is on energy efficiency and water conservation techniques (stormwater harvesting and sullage recycle, reduction in greenhouse gas emissions, use of recycled waste products (Fly ash based building elements) by acquiring an integrated design approach for reducing the operation and maintenance costs over the building duration.
WHAT IS GREEN BUILDING?
Buildings have major environmental impacts during their life cycle. Resources such as ground cover, water, forests, and energy are reducing to give way to buildings. Resource-intensive materials deliver structure to a building and landscaping adds attractiveness to it, in turn using up water and pesticides to preserve it. Energy-consuming systems for lighting, air conditioning, and water heating provide comfort to their residents. Hi-tech controls add intelligence to 'inanimate' buildings so that they can react to varying conditions, and intelligently observe and control resource use, security, and usage of fire fighting systems and other such systems in the building. Water, another essential resource for the occupants, gets consumed continuously during building construction and operation. Several building operations and occupant functions generate enormous amounts of waste, which can be recycled for use or can be reused directly.
AIM(OBJECTIVE) OF DESIGN GREEN BUILDING
The aim of a green building design is to minimise the demand for non-renewable resources, maximise the utilisation efficiency of these resources when in use, and maximise the reuse, recycling, and utilisation of renewable resources.
It maximises the use of:
- Efficient building materials and construction practises
- Optimise the use of on-site sources and sinks by bioclimatic architectural practices.
- Uses minimum energy to power itself
- Uses efficient equipment to meet its lighting, air conditioning, and other needs;
- Maximise the usage of renewable sources of energy.
- Uses efficient waste and water management practices; and provides comfortable and hygienic indoor working conditions.
ADVANTAGES | BENEFITS OF GREEN BUILDINGS
An inexperienced construction has to decrease useful resource consumption compared to traditional homes. The subsequent is the proportional reduction of various resources in a building and their respective motives.
1. Green buildings consume 40% to 60% (depending on the range of measures assumed) lesser electricity as compared to traditional buildings.
2. Green Buildings also try to work towards on-site energy generation through renewable energy utilisation to cater to its energy requirements. For example, solar thermal systems can help generate hot water and replace the conventional electrical geyser in buildings.
3. Green buildings consume 40% to 80% (depending on the range of measures adopted) lower water as compared to traditional buildings. By using ultra low-flow fixtures, dual plumbing techniques, waste-water recycling techniques and rain-water harvesting.
4. Green buildings affect lesser waste by employing waste management strategies on site. They may also employ waste to energy or waste to the resource (like manure, or compost) methods on-site, to minimise their burden on municipal waste management facilities and landfills.
5. Green buildings generate lesser pollution both during construction as well as while in use. Through best approaches such as proper storage of construction materials, barricading of the site to prevent air and noise pollution during construction, proper storage and disposal of waste during construction and operation ensure the reduced impact on the surrounding environment.
6. Green buildings assure proper safety, health and sanitation facilities for the labourers (during construction) and the occupants (while in use).
7. Green buildings confine the use of high ODP (ozone-depleting potential) substances in their systems as well as in finishes.
8. Green buildings offer a more elevated image and marketability.
FEATURES OF GREEN BUILDINGS
The green buildings involve extra initial costs but over the duration, these buildings turn out to be more economical. Besides, from the environmental and social concerns, it is desirable to go for green buildings. It is not essential to contain all green features in each building. Even if some of the green features are in individual buildings considerable advantage would accrue for the occupant and the environment.
