DAY II – Session IV
Dr. S. Raj Kumar, In charge – Centre for Excellence and Futuristic Development, Larsen & Toubro Limited, Chennai.
He explained that the concept of Green Building concentrates mainly on two points: Increasing the efficiency with which buildings use energy, water and materials and Reducing building impacts on human health and the environment, through better site selection, design, construction, operation, maintenance, and removal throughout the complete life cycle. The key concepts in designing a Green Building lies in its Sustainable Site Selection, Material Resources and Water Efficiency. Green Building standards also contain certain guidelines for the waste management. First of all, it seeks to generate minimum amount of waste possible during construction. Generally during construction, a large amount of waste material generated is dumped to landfills; this waste needs to be reduced. A building constructed with proper designing and following Green architecture standards produce less amount of waste as compared to other buildings. Indoor Environment Quality is a very important parameter to be considered for Green Buildings. It directly affects the health of occupants, which says that in buildings with good environmental quality, proper heating and cooling system ensures adequate ventilation, fresh air with in duct filtration system should be installed to improve the quality of indoor environment.
He also emphasized on the fact that Ventilation is a very important factor in maintaining healthy indoor air quality as it is responsible for air exchange which supports the health and comfort of building occupants. Effective design and planning for ventilation is necessary to reduce the requirement of artificial ventilation. Automated Building System techniques like HVAC (Heating, Ventilation and Air Conditioning) systems regulates the heating equipment and air conditioners on the basis of their sensor based network. The sensors control the equipments on the basis of indoor environmental conditions. Similar to this, sensor controlled lighting system which monitors the lighting appliances based on the availability of natural light are also used.
