Meteorological conditions vary significantly from year to year. For this reason, there is a need to create a typical meteorological year (TMY) data model, to represent the long term weather conditions over a year. TMY data is one of the main sources for successful building energy simulations. Two different typical meteorological data models were generated and compared: TMY and TMY-2. Both models where created by analysing every 3-hour weather data for a 30-year period (1984–2013) in Alūksne, Latvia, provided by the Latvian Environment Geology and Meteorology Centre (LEGMC). TMY model was created using statistical approach, but to create second model - TMY-2, 30 year average data were applied. In the TMY model creation representative typical meteorological months (TMM) were selected. TMM for each of the 12 calendar months were selected by choosing the one with the smallest deviation from the long-term average weather data. The 12 TMMs, selected from the different years, were used to create a TMY for Alūksne. The data gathered from TMY and TMY-2 models where compared with the climate data from the Latvian Cabinet of Ministers regulation No. 379, Regulations Regarding Latvian Building Code LBN 003-01. Average monthly temperature values in LBN 003-01 were lower than the TMY and TMY-2 values. TMY selection process should include the most recent meteorological observations and should be periodically renewed to reflect the long term climate change.
