The document outlines sustainability targets and strategies for developing special economic zones (SEZs) including optimizing building orientation, maximizing daylighting, reducing energy usage through efficient envelopes and HVAC systems, generating on-site renewable energy, minimizing waste, and encouraging non-motorized transportation. Case studies show potential energy savings of 39-55% compared to baseline standards through these integrated design approaches. The proposed designs could avoid 7,000 tons of CO2 emissions annually from one development.
