Senior Principal Lonnie Haughton presents this introduction of fundamental ‘real-world’ aspects of the properties of water in a manner that minimizes consideration of esoteric mathematical formulas to non-technically-minded construction professionals. The first iterations of this ‘Water 101’ paper were crafted in the early-2000’s in Seattle while Mr. Haughton trained as a building envelope consultant under Colin Murphy’s tutelage at Exterior Research & Design, LLC (now Trinity|ERD). Part A of this “Water 101” brief introduces seven basic (non-technical) aspects of fundamental properties of water molecules that – without careful attention when designing and constructing a building – can lead to destructive moisture accumulation at exterior walls. Some real-world ramifications of these basic concepts are further explored at Part B (which includes some technical discussion).
