The main environmental objectives of the building project are to save energy and water on the school premises, and to meet the criteria of Israeli Standard 5281- Buildings with Reduced Environmental Impact.
In planning the school buildings and courtyards, the main factors that will be taken into account - while balancing cost against effectiveness - are as follows:
Preservation of the Existing Environment
Minimal interference with the contours of the natural landscape; minimal harm to the very old trees growing on the premises.
Building and Finishing Materials
Preference for building and finishing materials with a green seal of approval in Israel or abroad, natural materials, recycled or recylable, and which have no adverse affects on health at any stage of their life cycle.
Recycling of Building Waste
All contractors will commit themselves to maintaining a clean site, as well as to recycling a large percentage of the waste formed during the building process, on and off-site.
Recycling and Trash Separation
Areas will be set aside for recycling and trash separation centers. This is both for practical reasons (making compost from organic waste for the school's gardening sector) and educational ones, as well as for the purpose of showcasing these methods.
After a study of climactic conditions and an analysis of solar factors, the buildings will be constructed in accordance with recommendations.
(1) Shading Shading of the various apertures of the buildings; assessing how much shade would be provided to the new buildings by the existing trees, in order to determine which trees should be left standing.
(2) Natural ventilation in accordance with prevailing local winds Openings for exits and entrances, the size and location of windows, choice of window opening types, upper and lower boundaries, roof ventilation, coupled with other ventilation methods such as wind catchers.
(3) Insulating and glazing Use of various insulation materials, including on the glazed portions of the building envelope; exploring the feasibility of green roofs.
Natural Lighting & Energy-Efficient Artificial Lighting
After an assessment of the expected illumination via the windows, we will apply recommendations on means for improving the natural lighting or the use of energy-saving, non-heat producing bulbs and fixtures.
Survey and pricing of various options for turning rooftops and awnings into areas for solar panels, or other technologies that will turn the school into a producer of clean energy and a consumer of clean electricity. The goal is to achieve a zero-consumption balance.
Infiltration of captured rainwater from the roofs and courtyards into the water table and recycling of gray water insofar as possible and within the confines of Health Ministry policy.
