Project: P-eser Impact Model

Hadas Pe'er has worked at the green building industry as an adviser, inspector, entrepreneur, planner and a manager. After several years of working among leading experts, organisations and companies Pe’er made the triple bottom line (i.e. Environment, Society, Economy = ESE) from her passion to her profession. Her business is focused on driving efficiency in existing buildings and retrofitting, while she also provides services to the green building local standard in different roles of expertise.


An organisation may donate few months of its energy efficiency’s gains, while still benefit the productivity of its own workers by using P-eser services. Those gains will finance the implementation effective solutions found to improve social non-profit organisation's structures.

The impact model completes the triple-bottom-line of sustainability. An organisation completes its energy efficiency process by implementing the most suitable solutions to its buildings and needs, considering its ROI and expenses. The main goal of an energy efficiency model is to drive efficiency and take care of the occupants’ well-being. The achieved savings will also reduce emissions and pollutant, for the avoidance of manufacturing and use of natural resources. To complete the social aspect of sustainability, the impact model allows organisations which completed their energy efficiency's implementation to donate several months of the gains made from that process. The donation will then finance an energy efficiency solution of non-profit organisations. This way, the impact from an energy efficiency completion of the organisation is valued with more than its own direct savings. It helps those who can't afford the process to become part of the solution and accelerate all sustainability aspects.


As a green building inspector, I was exposed to many new constructions, mainly in the centre of the country. Although green building aims to balance the triple bottom line (a.k. economy, society and environment), I felt there is an absence of equity. Those who needs the most financial support, could also afford themselves sick and squandered buildings.
