How do I change the Outdoor Design Temperature (ODT) for my project?

To change the ODT for your projectODT, follow these steps:

Note this will not affect the Outdoor Low Temperature (ODL) used in the performance task. Read here for more information. 

  1. Navigate to the Heat pump task
  2. Scroll down to find the Heat pump load section

  3. Click the pencil icon in the top right
  4. Set the temperature you want to use

An additional 0.3°C will need to be removed for every 50 m above sea level, with altitude given in the input section of the technical report & customer proposal.

Note this will not affect the Outdoor Low Temperature (ODL) used in the performance task, since this follows MCS 031 which states the the ODL from Appendix A must be used. The ODL is not the same as the ODT used for the design, which you may adjust within MCS rules stated in MIS 3005-d.
