What is test reference year?
Test reference year, typical meteorological year (TMY), or design reference year (DRY) are the names of datasets with a sequence of 8670 hourly data values of meteorological variables. Methodologies known as typical meteorological year use a modified version of Hall et al.
What is a design summer year?
DSY. The Design Summer Year is an actual continuous twelve month sequence of hourly data, from the 20-year data sets. It represents a median year with a reasonably warm summer.
Where does IES store weather files?
To access these in the IESVE software they should be copied into the weather subfolder of the Standard Data & Weather Files installation (typically C:\Program Files (x86)\IES\Shared Content). After this the new files are available to select on the Simulation Weather Data tab of ApLocate.
What is Cibse TM59?
TM59 is a standardised approach to predicting overheating risk for residential building designs (new-build or major refurbishment) using dynamic thermal analysis. The testing of the methodology has focused on flats, as they tend to represent a higher overheating risk than houses.
What is Cibse TM52?
CIBSE TM52. CIBSE TM 52 is the latest guidance for overheating in non-domestic buildings. The TM 52 calculation uses the CIBSE DSY (Design Summer Year) weather files which are selected from a 30-year baseline 1984 – 2013. There are 3 separate DSY weather files available which represent different types of hot summers.
What is Epw data?
Weather or climate files are textual files that contain data about weather conditions data for specific location for some time period. They contain data such as sky and sun irradiances, temperatures, wind speed etc. Example of such format is Energy Plus Weather Format (EPW).
What is a weather file?
Written by Marco Aguirre. A weather file is a text file containing daily observations of temperature, humidity, wind, solar radiation, and precipitation at various elevations that profiles a particular climate zone’s annual weather stream.

What is running mean outdoor temperature?
Were Tn is the temperature at each time interval, and α is a constant between 0 and 1. The temperatures Tn become less significant as time progresses, with the speed of decay depending on the value of the constant α.
What is meant by operative temperature in relation to comfort?
Operative temperature (previously known as resultant temperature or dry resultant temperature, but renamed to align with ASHRAE and ISO standards) is a simplified measure of human thermal comfort derived from air temperature, mean radiant temperature and air speed.
Where does CIBSE get its weather data?
The UK Meteorological Office (MO) collects weather data at stations across the UK. Climate variables measured at hourly intervals include air temperatures, wind speed and direction and air pressure etc. CIBSE licenses the historic weather data from the MO for 13 locations across the UK, and 3 in London.
What format does the data come in the CIBSE packages?
The packages are made up of data presented in all three formats – EDSL Tas, EPW & Excel. This is the old format used in IES software. IES have now switched to using EPW files. Files in this format are included in CIBSE’s 2016 weather data sets.
What are the CIBSE Guides?
The CIBSE Guides offer comprehensive technical guidance on key areas of building services engineering. The current set of Guides is listed below (click the titles for full details). The Guides can be freely downloaded by CIBSE members or ordered as a hard copy. PDF or hard copy versions can also be purchased by non-members.
