The ventilation required in order to maintain acceptable indoor hygiene standards results in a significant consumption of energy. Currently the Spanish regulations on indoor air quality (IAQ) require minimum rates for delivery-to and extraction-from the habitable rooms of residential buildings. These rates are not adjustable, so ventilation systems based on variable ventilation rates, are not normally deemed acceptable unless a comprehensive statement of compliance is provided, justifying the proposed ventilation solution.

Radon remedial measures do not last. After a few years the radon contents are again at a high level. This is shown by check measurements made in 110 dwellings in Sweden in which remedial measures against radon have been carried out.

A number of interzonal models have been developed to calculate air flows and pollutant transport mechanisms in both single and multizone buildings. A recent development in multizone air-flow modeling, the COMIS model, has a number of capabilities that go beyond previous models, much as COMIS can be used as either a stand-alone air-flow model with input and output features or as an infiltration module for thermal building simulation programs. COMIS was designed during a 12 month workshop at Lawrence Berkeley National Laboratory (LBNL) in 1988-89.

Popular culture abounds with uses for duct tape: duct tape calendars, books like 101 Uses for Duct Tape, and more. But lab experiments have finally proved that duct tape, as it ii' generally used, should not be used to seal ducts.
