Description

Meteorological reanalysis models provide hourly snapshots of the state of the atmosphere over an extended period oftime, typically since the dawn of the satellite era (1970s). In contrast to the operational weather forecast models on which they are based, reanalysis models focus on historical weather. From these historical snapshots a continuous weather time series can be assembled for all locations on Earth. For the purposes of ASHRAE, these “virtual” weather stations can then be used in the absence of more conventional stations, e.g.in the so-called “data deserts” found worldwide, to calculatedesign climatic conditions or as input to building simulation software. However, these virtual stations, being model-based, may not reflect the reality on the ground, putting building design at risk. ASHRAE thus sponsored a research project (1745-RP) to evaluate the feasibility of the use of reanalyses by its members. This paper provides some of the highlights of the project and provides general recommendations, warnings, and guidelines, for the use or reanalysis for building design.
