Economics

Economics tab in model data

 

When using Detailed HVAC you can define 3 aspects of building economics on the Economics tab at building level:

 

 

The data entered on the Economics tab will be passed to EnergyPlus to be included in simulations.

Note: You must have Economics and HVAC licence modules to work with the data on this tab. Detailed HVAC is required to provide access to components with the full set of EnergyPlus fuel types for tariff analysis and LCC. Simple HVAC cannot access tariff analysis (and hence LCC) as it uses ideal loads HVAC systems rather than EnergyPlus fuels.

Tariff Analysis

To calculate the costs of the utilities, fuels etc use the tariff analysis section of the Economics tab.

Include tariff analysis

To include a tariff analysis check the Include tariff analysis checkbox.

Number of tariffs

Enter the number of tariffs to be included in the simulation. You will be able to select a Tariff analysis component for each.

Tariff 1, 2 etc

Select the Tariff analysis component describing the characteristics of each tariff to be included. Up to 5 different tariffs can be selected depending on the Number of tariffs selected above.

Construction Costs

Include construction cost in simulation inputs

To include the construction capital cost of the building in the simulation you should check this checkbox. This must be done to include construction cost in a Life cycle cost calculation.

 

Summary results from the most recently run Cost calculation on the Cost and Carbon tab will be included in the "Component cost" component which is selected by default.

Construction cost

Select the Construction cost component.

Life Cycle Cost

Include life cycle cost analysis

To include a life cycle cost analysis check this check box.

Life cycle cost

Select the Life cycle cost component defining the analysis to be included in the simulation.
