The business case for high performance green buildings: Sustainability and its financial impact

Abstract

This paper endeavours to present building owners, managers, architects and design/builders with a compelling business case for considering a green building for their new construction projects. A green building, for the purposes of this paper, refers to any building that meets the high standards set forth in the US Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) Green Building Rating System™, the pre-eminent metric system by which new buildings are judged to be environmentally conscious. The financial benefits of green buildings are many. They include reduced energy consumption and their associated costs, increased occupant productivity and worker retention, increased market values, and reduced health liability risks due to better indoor air quality. Individual building measures are presented through a tertiary examination of two LEED Certified buildings. These individual benefits are examined further as an integrated building whole, indicating that buildings constructed to LEED standards can save more than 250 per cent of its up-front costs over the course of its 40-year useable life cycle.
