Evaluating Direct and Indirect Benefits of Green Office Buildings in Israel
This research evaluates the business case for the construction of green office buildings while quantifying the benefits – both direct and indirect – resulting from improved indoor environmental quality (IEQ). Green building construction provides both direct and indirect benefits: direct benefits mainly include savings on operating and maintenance costs; and indirect benefits affect building users by reducing illness, curtailing employee turnover and absence, increasing personal and organizational productivity, and boosting overall satisfaction. While there is difficulty in quantifying these benefits, studies conducted worldwide indicate that green office buildings increase productivity and improve the health and wellbeing of the buildings’ users. Given the fact that direct savings in operating and maintenance costs of green office buildings constitute only a small fraction of their overall economic benefits, the business case for green building construction is overwhelming.
