Abstract:
The construction sector accounts for a large percentage of the world’s total energy consumption and
green house gas emissions. One of the effective and intelligent initiatives in infrastructure sector is sustainable
development through green building concept. “Green Building” concept is a practice of creating structures and
using processes that are environmentally responsible and resources-efficient through the building life cycle.
Implementing the green building concept can result in reduction of carbon emissions by 35%, water usage by
40%, energy usage by 50% and solid waste by 70%. This paper also discuss the factors to be considered for
green building construction and the Leadership in Energy and Environmental Design (LEED) assessment
method to declare a building as a green building. The unique departure from traditional building model to green
model delivers savings in energy cost, reduction in water consumption, reduce in water cycling in green
building constructed in Sri Lanka are highlighted in the paper.
