Two certified Passive House Consultants, an architect and a builder, will talk about the tremendous benefits of the Passive House building approach, and nostalgically lament what this means for our now limited friendships with the boiler maintenance guy! They will review the design and construction principles that are employed to achieve a super-insulated, air-tight envelope and the essential addition of continuous mechanical ventilation. Looking at both single family and multifamily construction, they will share details, testing data, and lessons learned to demonstrate how to radically reduce energy consumption and construct a super-efficient, cost-effective building that will be comfortable, highly durable, healthy to be in, and affordable to operate.
