The living space in this new home built by Global Green in the Lower Ninth Ward of New Orleans is elevated four feet (1.2 m) to keep it above expected flood level. Numerous other "passive survivability" features are included.
- Design cooling-load avoidance measures into buildings
- Design natural ventilation into buildings
- Limit internal gains by specifying high-efficiency lighting and equipment
- Model energy performance with higher cooling design temperatures
- Provide landscaping to minimize cooling requirements
- Address urban heat islands in building design and landscaping
- Plan for termite ranges extending north
- Avoid new development in the driest regions
- Specify water-efficient fixtures and appliances
- Plumb buildings with water-conserving fixtures in mind
- Plumb buildings for graywater separation
- Harvest rainwater
- Plant native, climatically appropriate trees and other vegetation
- Avoid building in (expanding) flood zones
- Expand stormwater management capacity and rely on natural systems
- Design buildings to survive extreme winds
- Raise buildings off the ground
- Specify materials that can survive flooding
- Install specialized components to protect buildings from flooding or allow flooding with minimal damage
- Elevate mechanical and electrical equipment
- Install check valves in sewer lines
- Begin planning for rising sea levels in coastal areas
- Specify Class A roofing
- Eliminate gutters or design and maintain them to minimize fire risk
- Avoid vented roofs or protect vents from ember entry
- Install high-performance, tempered windows
- Choose deck materials carefully
- Install noncombustible siding
- Manage vegetation around homes
- Design buildings to maintain passive survivability
- Provide dual-mode operability with high-rise buildings
- Design mechanical systems to operate on DC power
- Provide site-generated electricity from renewable energy
- Provide solar hot water
- In urban and suburban areas, maintain access to the sun
- Plan and zone communities to maintain functionality without power
