Enclosure Best Practices: Roofs, Walls, and Floors

Building enclosures – the roof, walls, and floor – are the first line of defense between nature and people. Enclosure performance is optimized when air sealing and insulation – two under appreciated and typically underperforming features – are done to high-performance standards rather than the status quo. The preceding class in our High-Performance Fundamentals program (How Buildings Work; Science and Buildings and Science in Buildings) covered the scientific principles needed to effectively design high-performance buildings.
