Recent developments in climate analysis at ASHRAE and others have greatly increased the breadth as well as accuracy of climatic data needed for HVAC design calculations and building energy simulations. This seminar introduces these developments, including: ASHRAE's 2013 Handbook of Fundamentals containing design conditions for 6,443 locations; the National Climatic Data Center providing weather data and services for tens of thousands of stations worldwide; satellite-derived solar radiation providing accurate and uninterrupted solar data for any place in the world, which NREL is combining with reanalysis data to produce the next generation ofgridded TMYs for more than a million U.S. locations.
