During winter experiments in central Pennsylvania a windbreak, 61 metres long and composed of a single row of white pine trees, significantly reduced air infiltration rates and space heating energy needs in a small mobile home by upto 54% and 18% respectively. Greatest reductions in air infiltration rates occurred with the home at one windbreak height (1H) downwind, even though maximum reductions in wind velocity occurred at 2H or 4H downwind. Space heating energy savings were less sensitive to downwind position, with maximum energy savings measured at both 1H and 2H. Maximum energy savings due to the windbreak for an entire winter heating season were estimated to be 12%.
