The 2012 Building Science Summer Camp began last night as people from around the US and Canada arrived in Westford Massachusetts for what is officially called the Westford Symposium on Building Science. I got in at about 7 pm and…
Remember those old metal playground slides? You don't see them all that much anymore, but recently I found one. It was in the quaint little Southern town of Rutledge, Georgia, near the Hard Labor Creek Blueberry Farm where I'd been…
Heating, ventilating, and air conditioning (HVAC) systems have undergone great development since our cavemen ancestors huddled around the fire in winter and fanned themselves with palmetto leaves in summer. The rapid development of efficiency and performance experienced by other industries,…
