Implementation in the Design Process:
During site selection, consider sites where existing vegetation or site features provide shading that can be integrated into the built area. Also evaluate effects of maturing plantings or changing uses on future heat island effects. Consider sharing building space or amenities, such as parking, to minimize the development footprint and surfaces that promote the heat island effect.
Through the design process preserve or propose landscape features that provide shade for surfaces that contribute to the heat island effect. Orient the building and pavement surfaces that maximize shade for surfaces that contribute to the heat island effect. Minimize building and pavement surfaces that are exposed to the sun. Consider replacing impervious surfaces (i.e., roofs, sidewalks, roads, driving lanes, etc.) with open-grid paving or high albedo materials. Consider replacing roofing surfaces with high albedo materials or vegetated surfaces.
Monitor submittals for compliance with plans and details. Make bidders aware of specific requirements for heat island reduction.
During occupancy, monitor and maintain vegetation around site to preserve its beneficial effects and mitigate negative developments.
