Building heating loads were generated with Energy Plus for both a typical weather year from the International Weather for Energy Calculations (IWEC) data (ASHRAE 2001) and the actual 2012 weather.
In addition, this study has illustrated some of the limitations in available emissions data--better time resolution and more accurate source emissions data would be highly desirable, as would further development of models that could be used to predict time-varying emissions for typical weather years.
Typical weather year files like TMY are commonly used in building simulations to estimate the annual energy consumptions since analysis using a multiyear dataset is often not feasible and economical for the common design and analysis problems; representative days are too limited and often not accurate enough for a specific design and analysis problem .
Brunger, "The development of typical weather years for international locations: part I, algorithms," ASHRAE Transaction, vol.
 developed the typical weather year
files for two neighboring cities, namely, Hong Kong and Macau.
Typical weather year
data options include ASHRAE's Test Reference Year (TRY), Weather Year for Energy Calculations (WYEC), International Weather for Energy Calculation (IWEC) and the National Climatic Data Center's (NCDC) Typical Meteorological Year (TMY).
(2010) compared simulation results using a variety of typical weather year
selection approaches (TMY, IWEC, and TMY2) and those obtained by averaging the results for 30 years for ten U.S.
where HDH and CDH are the number of annual heating and cooling degree hours in the given month for a typical weather year

Several approaches have been utilized to develop and format a typical weather year
for building energy analysis including the ASHRAE Test Reference Year or TRY (ASHRAE 1976), Typical Meteorological Year or TMY (Hall et al.
In the US, several approaches have been proposed to select a typical weather year
for building energy analysis including the ASHRAE Test Reference Year or TRY (ASHRAE, 1976), Typical Meteorological Year or TMY (Hall et al., 1978), the Weather Year for Energy Calculations (Crow, 1981), and TMY2 (Marion and Urban, 1995), and more recently TMY3 (Wilcox and Marion, 2008).
