***Session 4: Plugging the Holes - Inviting In Free Energy, and Trapping Escaping Energy | 3.5 Hours***

Interestingly, it has become evident that traditional thinking about mechanical systems and their role in more energy efficient homes begins to fall apart when we look at Net Zero homes and beyond. There are passive solutions to energy recovery of ventilation air, there is great reduction in heating and cooling devices (both capital and operating costs) as the building enclosure gets tighter and more thermally resistive. Where is the balance between more costly mechanical and more effort in the design and construction of the building envelope? Why does falling snow stick to the ground last over the manhole covers in the streets? Can power controlled louvre windows be used to naturally ventilate the home while providing stack cooling and even night purging of heat? The answers lie in knowledge and in undertaking careful design that can bring passive comfort and ventilation into the home with little or no energy requirement.
