The Future of High-Performance Green Buildings
Buildings Technology R&D Vision
Enable designs of new buildings and retrofits
of 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.
