Air seal and insulate flex ducts
Image
Air seal duct boot to ceiling by installing fiberglass mesh tape and mastic over seam
Image
Image
All other supply ducts and all return ducts in unconditioned space have insulation ≥ R-6
Image
All return air and mechanically supplied outdoor air pass through filter prior to conditioning
Image
An air vent mounted high on the radiator will shut quickly and limit the radiator’s heat output
Image
An air vent mounted low on the radiator will allow more steam to enter the radiator before it shuts

Image
An energy recovery ventilator (ERV) transfers both heat and moisture between incoming and outgoing streams of air
Image
An Energy Recovery Ventilator provides outside air to this dwelling unit; a range hood with dedicated makeup air provides local kitchen exhaust; a Packaged Terminal Heat Pump provides conditioned air and dehumidification is provided separately

Building cavities not used as supply or return ducts unless they meet Items 3.2, 3.3, 4.1, and 4.2 of this Checklist
Image
Image
By plotting the heating capacities at -4°F and 5°F and drawing a line between them, the capacity at 0°F can be estimated
Image
Cavity used for return is not insulated and is not air sealed, which will pull in air from outside
Image
Image
Central-fan-integrated supply ventilation with exhaust fans for intermittently balanced whole-house ventilation
Image
Image
Clothes dryers vented directly to outdoors, except for ventless dryers equipped with a condensate drain
Image
Collars that are specifically made for flexible duct have a raised bead to prevent the duct from slipping off
Image
Image
Concept behind an evaporative cooler – warm air is cooled as the air passes through a wet medium and gives up some of its heat to evaporate the water
Image
Condensate from this heat pump water heater is routed to a nearby floor drain, shared with the condensate lines from a condensing gas furnace and an air conditioning coil
Image
Connect the plastic application tunnel from the injection equipment to the supply plenum.
