1613-RP: UPDATE CLIMATIC DESIGN DATA IN CHAPTER 14 OF THE 2013 HANDBOOK OF FUNDAMENTALS
TC 4.2 Climatic Information  Co-sponsor, TC 4.1 Load Calculation Data and Procedures
The climatic design conditions in the HOF Chapter 14 are fundamental for the sizing and design of building energy systems to allow for optimal energy efficiency measures and ensure that the design conditions are related to the energy system capacity to meet the climatic loads in a probabilistic sense. Regular updating of the climatic conditions is critical in this respect for many practical reasons and to show due diligence in a world of changing climate.
