Hadera Courthouse
A pioneer project in Israel achieving a nearly net-zero energy design. The first public assembly building in Israel to achieve 3 stars under Israeli Standard SI-5281.
Achievements
Energy rating A; HVAC at COP 5.8 – 13% more efficient than code
214 kWp high-output rooftop PV
External thermal insulation, architectural shading, and an ecological pond
Background
The Hadera Courthouse was the first public assembly building in Israel to target nearly net-zero energy design, aiming for at least 80% overall energy savings vs. standard practice, through an integrative design process with the developer and design team.
Approach
It followed a 3-step methodology: (1) passive architectural design — optimized orientation, thermal insulation, external shading, window areas and specs; (2) energy-efficient MEP systems — LED lighting, high-efficiency inverter chiller, variable-speed drives; (3) maximized on-site renewable energy via a rooftop solar PV system of over 230 kWp.
