What is the TER040 datasheet?
The TER040 datasheet - Replacement of a climate control generator with a heat pump in a tertiary building - covers the installation of heat pumps in tertiary-sector buildings (offices, hotels, shops, hospitals, educational centres) to replace conventional boilers, electric resistance heaters or low-efficiency climate control equipment.
It is one of the datasheets with the highest energy-saving potential per action, especially when gas boilers are replaced by heat pumps with a SCOP above 3.5.
Scope of application
- A tertiary-sector building (offices, hotels, hospitals, shops, educational centres, etc.)
- Replacement of an existing heat and/or cold generator
- Installation of an electric heat pump (air-source or geothermal)
- The heat pump must cover the heating and/or cooling needs
Calculation formula
The saving is calculated by comparing the consumption of the old system with that of the new heat pump system:
Saving (kWh/year) = (Dcal/Rend_cal + Dref/EER_ref) - (Dcal/SCOP + Dref/SEER)
Where:
- Dcal: heating thermal demand (kWh/year)
- Dref: cooling thermal demand (kWh/year)
- Rend_cal: efficiency of the old heat generator
- EER_ref: EER of the old cooling equipment
- SCOP: seasonal coefficient of performance in heating of the new heat pump
- SEER: seasonal coefficient of performance in cooling of the new heat pump
Worked example
An 80-room hotel in climate zone D3 (Madrid):
- Heating demand: 350.000 kWh/year
- Cooling demand: 200.000 kWh/year
- Old system: gas boiler (efficiency: 0.85) + chiller (EER: 2.5)
- New system: air-source heat pump (SCOP: 4.2 / SEER: 5.8)
Consumption before = 350.000/0,85 + 200.000/2,5 = 411.765 + 80.000 = 491.765 kWh/year Consumption after = 350.000/4,2 + 200.000/5,8 = 83.333 + 34.483 = 117.816 kWh/year Saving = 491.765 - 117.816 = 373.949 kWh/year = 374 MWh/year Total CAE = 374 MWh Valuation: 374 MWh x 100 EUR/MWh = 37.400 EUR
A single heat pump action in a hotel can generate more than 143.000 EUR in CAE. This illustrates the enormous potential of the TER040 datasheet for delegated subjects.
Critical parameters: SCOP and SEER
The SCOP and SEER values are the most important parameters of the TER040 datasheet:
- The SCOP (Seasonal Coefficient of Performance) measures the seasonal heating efficiency. A SCOP of 4.0 means that for each kWh of electricity consumed, the heat pump produces an average of 4 kWh of heat over the season
- The SEER (Seasonal Energy Efficiency Ratio) measures the seasonal cooling efficiency. A SEER of 5.5 means 5.5 kWh of cooling for each kWh of electricity
- These values must come from the manufacturer's datasheet and be certified in accordance with European regulations (Regulation 206/2012 or 813/2013)
Required documentation
- D1: datasheet of the old climate control equipment (boiler, chiller), the building's energy performance certificate if available, thermal demand data
- D2: datasheet of the installed heat pump with certified SCOP and SEER
- D3: invoice or contract for the installation
- D4: photographic report of the old equipment and of the new equipment installed
- D5: supporting calculation of the energy saving
Common mistakes with the TER040 datasheet
- Confusing the nominal COP with the seasonal SCOP (the verifier requires the seasonal value)
- Not having the certified datasheet of the heat pump with SCOP/SEER
- Overestimating the thermal demand without supporting evidence (gas invoices, energy performance certificate)
- Applying the TER040 datasheet when it should be IND060 (same type of action but in an industrial premises)
- Not documenting the reference system (old equipment) once it has already been removed
