over typical year

expressed as a percentage; it is the ratio between the appliance's output capacity
compared to it's input capacity

Assessing Existing Insulation - ANSWER-Good: no gaps or imperfections are present
Fair: there are gaps in over 2.5% of the insulated area; this equals a 3/8-inch space
along a 14.5-inch batt

electronics
water-saving measures such as low-flow showerheads and faucet aerators

Bay - ANSWER-the space between and the size of the wood influence the cavity or bay
(indicates the amount of insulation)

Before attempting any of the air sealing work, it is important to: - ANSWER-Walk
