Green construction is gaining foothold among professionals, decision makers and the broader public. However, its success depends on a clear minded analysis of its pros and cons based on critical assessment, including cost-benefit analysis. This paper makes a first attempt at such an analysis of some of the first green sustainable schools in Israel. It deals with a limited sample available, as well as diverse rating systems which the different architects have chosen to comply with.
By identifying and isolating the “green premium” of those schools which are comparable, and by analyzing actual direct benefits for the schools through energy and water bills (23% and 24% lower consumption respectively per year), the paper concludes that for the time being the payback period of green schools in Israel may prove counterproductive and prohibitive if calculated only on the basis of these two direct and immediate benefits. However, including in the analysis additional benefits, e.g. staff satisfaction (included in this paper), student achievements, user and broader public health issues and other public benefits (not included in this paper) can change the cost-benefit analysis outcome significantly.
