The truth is that commonly espoused energy-saving tips are worthless. We look at four common offenders.
Comparing the performance of a cellulose-insulated double wall against the same wall insulated with two different thicknesses of low-density open-cell spray foam.
Mini-split heat pumps were a major topic at the Northeast Sustainable Energy Association (NESEA) BuildingEnergy 14 conference in Boston this year. Ted Cushman explains why and how these mini-splits shine in cold climates.
