   • For flats on the fourth floor and above there is now an additional box Party floor storey
      which can be used to set the party storey number for EPC submissions.
   • CSH report. Now uses revised equation for cooking emissions and the standard case DER
      now uses the reduced emissions set from Table 5.
   • Regulations checklist now takes project status (as designed/as built) from the
      Project Information dialogue, not the air pressure test status.
   • Now allows community heating scheme together with dhw from an immersion heater.
      Set the primary heating to Community heating scheme and the source of domestic hot water
      to Hot water tank then set the size and insulation and single/double coil immersion.
   
3. U-values:
   • Now possible to put in a different surface resistance for the underside of a suspended
      ground floor to allow for a low emissivity surface.
