Hea 06 – Security

  • This issue now specifically relates to security only. Safety criteria has been moved to Hea 07.
  • Exemplary level credit now available.
  • Suitably Qualified Security Specialist definition updated.

‘Energy’ changes

Ene 01 – Reduction of energy use and carbon emissions

  • All assessment types have 9 credits available.
  • 4 additional credits are available for Prediction of Operational Energy Consumption for all assessments apart from Shell Only. These are awarded by undertaking additional design and post construction stage energy modelling and reporting consumption targets.
  • New EPRNC benchmarks.
  • Up to 5 exemplary credits are available for all assessment types other than Shell Only.
  • Simple buildings have 9 credits available for EPR and 7 exemplary credits available.

 

Ene 02 – Energy monitoring

  • New criterion for sub-metering of high energy load and tenancy areas for single occupancy buildings.

 

Ene 03 – External lighting

  • Benchmark has been updated for average luminous efficacy.

 

Ene 04 – Low carbon design

  • Passive design analysis and low zero carbon feasibility study criteria amended. A ‘meaningful reduction’ in energy is not now needed, instead, the reduction needs to be quantified.
  • Free cooling credit now only available to naturally ventilated buildings.

 

Ene 07 – Energy efficient laboratory systems

  • Prerequisite to meet Hea 03 requirements has been removed.

 

Ene 08 – Energy efficient equipment

  • The issue will now not be applicable where there will be no unregulated energy consumption in a development.
  • Small power has been removed as an entry in the examples of solutions table. Small power can still be considered the significant contributing unregulated energy consumption of the building and assessed.
  • Drying space requirements from Ene 09 in 2014 have been incorporated into this issue.

 

Ene 09 – Drying space

  • This issue has been removed from the 2018 scheme.
