LEED: Comparison Between Homebuilding And The Sustainable Environment

between homebuilding and the sustainable environment. Leadership in Energy and Environmental Design (LEED) is a set of rating systems for the design, construction, operation, and maintenance of green buildings. This paper gives a jest about green building and its goals. It is mainly about LEED, its development, the rating system, new versions and its overall performance. The comparison between LEED buildings and non-LEED buildings is done and the controversies are highlighted. It also discusses about whether it is reliable or not and its role in India.

I. INTRODUCTION The term "technology" refers to the application of knowledge for practical purposes. The field of "green technology"

They are found in all types of fields such as energy , green building, environmentally preferred purchasing, green chemistry, green nanotechnology, green architecture, sustainable development, green computing etc.

II. GREEN BUILDING

Green building refers to both a structure and using of processes that are environmentally responsible and resource efficient throughout a buildings life cycle: from sitting to design, construction, operation, maintenance, renovation and demolition. A well maintained cooperation is required for this to work. The main goals are utility of the building, durability, and comfort of the occupants.

The main objective is to reduce the overall impact of the built environment on human health and natural environment by efficiently using energy, water and other resources, protecting occupant health and improving employee productivity, reducing waste pollution and environmental degradation.

One way to construct a green building is to use natural materials or to retrofit the existing building through public schemes for energy efficient refurbishment.

Newsham et al. published a detailed study on IEQ and LEED buildings in August 2013. Field studies and Post-Occupancy Evaluations (POE) were performed in 12 “green” and 12 “conventional” buildings across Canada and the northern United States. On-site, 974 workstations were measured for thermal conditions, air quality, acoustics, lighting, workstation size, ceiling height, window access and shading, and surface finishes. Responses were positive in the areas of environmental satisfaction, satisfaction with thermal conditions, satisfaction with view from the outside, aesthetic appearance, reduced disturbance from heating, ventilation and air-conditioning noise, workplace image, night-time sleep quality, mood, physical symptoms, and reduced number of airborne particulates. The results showed green buildings exhibited superior performance compared with similar conventional
