Defining the general project details
The "General data" section of the main toolbar contains the tools for defining the following aspects relating to the cost analysis of improvement measures or alternative building designs.
Energy costs
This allows you to define the cost of energy by energy source, in units of the selected currency per unit of energy. This information is used in the economic analysis carried out by the program.
The energy vectors for which this configuration can be applied are as follows:
- Electrical grid energy
- Natural gas
- Diesel
- LPG
- Carbon
- Solid biomass
- Biomass
- Thermal energy taken from the environment (including solar thermal energy)
- Electricity generated by photovoltaic panels, small wind turbines and small hydro turbines
Net Present Value
This allows you to enable the Net Present Value (NPV) calculation method to carry out a more detailed analysis of the payback period associated with the various improvement measures entered, and to configure its parameters.
- NPV calculation method (optional)
The method used by the programme to calculate the payback period is static analysis. If this option is enabled, dynamic analysis is included in the calculation.
The parameters to be defined when this calculation is enabled are as follows:
- Annual energy costs increase (%)
- Discount fee (optional) (%)
- Forseen inflation (%)
- Nominal interest type (%)
- Analysis period (years)
