Report in table format the characteristics of selected variants/measures/packages that are applied for the cost-optimal calculation. Please start with the most common technologies and solutions and then move towards the more innovative ones. If there is evidence from previous calculations that measures are far from being cost-optimal, no table has to be filled in but this should be reported separately to the Commission. The format below can be used, but please note that the examples listed are purely illustrative.
Table 4
Illustrative table for listing selected variants/measures
| Each calculation should refer to the same comfort level. Pro forma each variant/package/measure should provide the acceptable comfort. If different comfort levels are taken into account, the base of the comparison will be lost. | ||||
| Measure | Reference case | Variant 1 | Variant 2 | Etc. … |
|---|---|---|---|---|
| Roof insulation | ||||
| Wall insulation | ||||
| Windows | 5,7 W/m2K (description) | 2,7 W/m2K (description) | 1,9 W/m2K (description) | |
| Share of window area of total building envelope | ||||
| Building-related measures (thermal mass, etc.) | ||||
| Heating system | ||||
| DHW | ||||
| Ventilation system (incl. night ventilation) | ||||
| Space cooling system | ||||
| Measures based on RES | ||||
| Change of energy carrier | ||||
| Etc. | ||||
The listing of measures is purely illustrative.
For the building envelope: in W/m2K
For systems: efficiency
Several levels of improvements can be selected (for example: different thermal transmittance values for windows)
