The Future of High-Performance Green BuildingsBuildings Technology R&D VisionEnable designs of new buildings and retrofitsof existing buildings that over the life cycle:

• Produce as much energy as they consume (NZEB).

• Double the service life of building materials, products, and systems and minimize life cycle impacts.

• Reduce domestic water use by 50% (to 50 gal/day per person), maximize water recycling and rainwater harvesting, and minimize stormwater runoff.

• Achieve breakthrough improvements in indoor occupant health, productivity, and comfort.
