The new Eco-Building of the Porter School of Environmental Studies is a result of a design competition held in 2008 by Porter Foundation, to design the first Green Building in the Tel Aviv University. The building is designed to employ a range of environmental technologies, and to be used as a laboratory for studying green building and environmental research.
The Building received LEED Platinum certification – the highest accreditation of the LEED certification system, developed by the U.S. Green Building Council (USGBC). The project received 92 points . This score places the building among the leading green buildings worldwide (so far only 17 buildings in the world scored over 90 points!).
The Eco-Building has been designed for energy and water conservation. Three of its main features are: the atrium, a glassed lobby and an exhibition space (shaded by the EcoWall); the EcoWall, located at the Sothern façade of the building, was designed to serve as a research space; and the Capsule, a unique room for meetings, seminars and workshops. The Capsule will be covered with a LED display of environmental information, such as the building energy consumption and the level of environmental pollution. The building is currently under construction.
Research and EcoDesign served as a daylighting consultant for the Porter School Eco-Building. During early stages of design, daylight simulations were carried out, to estimate illuminance and glare levels. Accordingly, several modifications of the building façade were made. In later design phases, additional daylight simulations were made to ensure compliance with the daylight requirements of LEED standards (and yielded maximum 3 points for credit 8.1).

The Zin Elementary School, named after Andre and Katherine Merage, which is located at the Ben-Gurion educational campus, was chosen by the Israeli Ministry of Education to be planned as one of 6 green schools in honor of 60 years of Israel’s independence. Therefore it was planned to accommodate the local desert climate. The design employed several climatic strategies, such as passive cooling of the building mass through summer night ventilation, and winter passive heating through southern windows. In addition, a special emphasis was given to providing quality daylight, to ensure quality daylight, which alongside significant energy conservation considerably improves the pupils performance, mood, and health.
In order to establish quality daylight, classroom windows were oriented to the south and to the north, the southern windows included upper windows and light shelves, Roof Monitors were designed to enable better daylight in the classroom depth, and in the window interior, shading systems were installed to prevent glare from low winter sun angles. To take advantage of the daylight and to improve energy efficiency, efficient lights were installed. These were divided into electrical circuits according to zones of daylight availability, and were controlled by light and occupancy sensors.
Beside the main windows, in all classrooms additional (upper and side) windows were designed to provide cross natural ventilation. Such ventilation provides fresh air, helps in releasing hot air (naturally produced by the pupils), and improve thermal comfort in spring and fall. In addition to the mechanical systems of cooling and heating, additional systems of forced ventilation were installed to comply with the requirement for fresh air and to cool the building mass (interior walls and floors) through night ventilation during summer. The building envelope consists of interior thermal mass and exterior insulation to improve the efficiency of cooling. Passive heating of the classrooms and halls was established through Sothern windows.
The design process included climatic and sustainability consulting from the early stages of design, and the use of climatic simulations to support design decisions in these early stages. The design process included practical-research (which is applied research carried out in practice, enabling better climatic performance); and in the framework of post occupancy evaluation, illuminance measurements and luminance photography were carried out.
