We're always on the lookout for the healthiest and most sustainable building products. In an ideal world we'd build exclusively from a material that is:

• 100% recyclable
• Made from 100% recycled material
• Extremely durable and long lasting
• Zero maintenance
• Light weight
• Very strong in both compression and tension
• Inexpensive to produce
• Produced locally
• Healthful to produce — and creates no harmful substances in its production or use.

Currently, we're looking for these systems and materials — our "hot list:"

• Low maintenance exterior cladding, including concrete panels, metal panels, and refrigeration panels
• Rain screen systems
• Low flow faucets
• High insulation windows, skylights, and transparent panels
• A whole-house water filtration system
• Alternate structural systems, including SIPs and aluminum frames
• Panelized interior ceilings and walls
• Lighting and lighting control systems
