With no/ultra-low load homes, research

addresses other loads, renewables, and

transaction process

As thermal loads continue to shrink,

reducing other loads become critical. Also need to address ‘O’

value in trans. process.

Thermal loads becoming so small,

need low-load HVAC and whole-house dehumid. due to

longer swing seasons.

Tighter, better insulated homes demand water management,

ventilation and IAQ.

As codes ramp up, critical research

continues to address effective insulation, air sealing, and windows.

With advent of insulation in codes,

critical research addresses effective

insulation, air sealing, and windows.
