The Systems tab enables user to specify non-template based selections of the Heating, Ventilation and Air Conditioning (HVAC) parameters applied to the room. System selections are based on Apache System discussed in the above section.
For compliance assessments, the important parameters on the System tab are the following.
HVAC system – this indicates the Apache System serving the room’s space conditioning needs
DHW system – this indicates the Apache System serving the room’s hot water needs including any solar energy system. An individual DHW system is recommended.
Note: iSBEMgi_v4.2.a includes a tick box to define “No HWS in the building”. Within Gibraltar Part F (2007) DSM compliance the user can implement this via:
