ENE 05 - Cooling

District heating / cooling / hot water – entering data into the Online Platform - KBCN1536

For assets which use district heating / cooling / hot water, information on the district systems are entered into Ene 09a and 09b. In Ene 05 / 06 / 09, answer 'no' to first question "Is space heating / cooling / hot water generated on-site?" then navigate to:

• Ene 09a to answer questions on district cooling.
• Ene 09b to answer questions on district heating and hot water. A district heat network will also provide hot water, so information on the system which provides both is entered into Ene 09b.

The Online Platform differs from the manual structure, however it does not affect scoring in any way. All data entered contributes to the asset energy calculator. Assets with on-site and off-site systems Only answer questions on the system which provides the most signifcant heating or cooling to the asset. If an asset includes both on-site and off-site systems, choose the one which delivers the most energy annually.

Erratum – V6.0.0 – cooling efficiency parameter – EER / SEER - KBCN1560

In the asset energy calculator guidance, the parameter given for cooling efficiency is 'SEER' (Seasonal Energy Efficiency Ratio). This is incorrect and should say 'EER'. This affects the following tables:

	International	USA
Commercial V6.0.0	Table 19	Table 18
Residential V6.0.0	Table 16	Table 16

This will be updated in the next manual re-issue.

Systems serving <10% overall floor area - other affected issues - KBCN1542

The methodology for Ene 01 states: "Heating / cooling systems can be excluded from the calculation where the heated or cooled area equates to less than 10% of overall floor area." Systems which heat or cool < 10% overall floor area are not assessed in:

• Ene 01 Building services.
• Ene 05 Cooling.
• Ene 06 Heating.

Ene 01, 05 and 06 all feed into the asset energy calculator and so their inputs must be consistent. All other issues relating to these excluded systems are still assessed such as:

• Ene 11 Installed controls.
• Ene 15 and 16 Monitoring energy issues.
• Pol 03 Local air quality.
• Pol 04 Global warming potential of refrigerants.
