Five renewable system types are available for use within the SBEM actual building:
· Photovoltaic systems (PVS)
· Wind
· CHP
· Transpired solar collectors (TSC)
· Solar water heating
The first four are defined on the Electricity generators dialog (toolbar) and the last is defined per DHW system on Apache Systems dialog.
CHP should be sized to provide the base load of heating for the building and the power generated will be used to offset the electrical energy usage in the building.
Wind and photovoltaics will, when the prevailing weather conditions permit, provide electrical energy that will offset electrical energy usage in the building.
Note: Solar water heating is not classified as a renewable in the SBEM outputs.
Note: the parameters and models of renewables are different between SBEM and ApacheSim. In most cases the ApacheSim model is more sophisticated.
