Defining location data in the "Thermal loads" tab
Project location data is defined using the "Location data" option in the "Project" section of the top toolbar in the "Thermal loads" tab.
The data available for configuration are as follows:
- Location
- Latitude
- Longitude
- Elevation
- Foreground solar reflectance
- Time zone
- Summer Time (DST) (optional)
- First month
- Last month
- Heating design conditions
Set the data required for calculating heating loads:- Dry temperature
- Relative humidity
- Ground temperature
- Cooling design conditions
View the data required to calculate monthly cooling loads. By clicking on any cell in the table, you can change the value of each parameter for each month:- Design dry-bulb temperature
- Mean coincident wet-bulb temperature
- Daily dry-bulb temperature range
- Daily wet-bulb temperature range
- Clear sky optical depth for beam irradiance
- Clear sky optical depth for diffuse radiance
Automatic data import
The "Import" option in the top right-hand corner of the "Site data" window lets you automatically import data from various climate databases. These include the following:
ASHRAE Weather Data Viewer 6.0
The climate data required for the calculation can be imported from ASHRAE’s Weather Data Viewer 6.0 climate database, which contains 8,118 stations located around the world. Solar radiation data is calculated using ASHRAE’s Clear-sky Solar Radiation model.
- WMO region
- Country
- Station name
- Annual percentile value (Heating) (99.6% / 99%)
- Annual percentile value (Cooling)
- Annual temperatures (0.4% / 1% / 2%)
- Monthly temperatures (0.4% / 2% / 5%)
- Latitude
- Longitude
- Altitude
Data import for Spain, France and Portugal
This data is sourced from various reference standards for the countries mentioned. By clicking on the options with the flag symbols on the right, you can specify the exact location of the project within each of these countries. Once you confirm, the following details will be filled in:
- Location
- Latitude
- Longitude
- Altitude
- Heat design conditions
- Dry temperature
- Relative temperature
- Ground temperature
- Cooling design conditions
- Design dry-bulb temperature
- Mean coincident wet-bulb
- Average annual oscillation
