Overall Aims

• Most importantly – make the most efficient use of energy consumed
• Consider sourcing renewable and cleaner sources of energy (whether it be from ‘near-site’ district Combined Heat and Power schemes, onsite renewables, or offsite renewables delivered via the national grid)
  

Measurement

• Measure all forms of energy consumption (electricity, gas, other fuels, thermal energy), in kiloWatt-hours (kWh)
• Take actual meter readings – estimations/invoices are not sufficiently reliable
• The more frequent meter readings are taken, the better
  • annual or quarterly can suffice for basic reporting, but for active management,
    monthly or half-hourly (with automatic meters) readings are advisable
• Understand and improve the metering arrangement in the property – good sub-metering underpins successful energy management, as well as enabling accurate re-charging from landlord to tenant
• Make proactive use of energy consumption data, using appropriate monitoring and targeting techniques
  

Specific Actions

• Ensure that all Building Management System (BMS) controls are optimised, often BMSs have never been properly commissioned
• Promote awareness through a ‘switch off’ policy, e.g. placing stickers above light switches
• Lighting, heating and cooling in unoccupied areas should be switched off, but remember to consider health and safety
• As part of routine maintenance, ensure:
  • light fittings, windows, occupancy and daylight sensors are clean
  • old/dim lamps are replaced
  • HVAC equipment is serviced regularly
• Utilise natural ventilation and ‘night cooling’
• Make sure heating and cooling do not operate at the same time (e.g. no heating or cooling between 19^oC and 24^oC - a ‘dead-band’ of 5 ^oC)
• Customers wear warmer clothing if it is cold outside, so indoor temperatures should be set to avoid them becoming uncomfortably hot, and staff uniforms should not require excessive heating for them to be comfortable
• Install time controls so that equipment (such as escalators and vending machines) only run during opening hours
• As part of refurbishment, check the credentials of contractors to see if they are accomplished at creating quality environments that are also energy efficient

Performance Threshold

The energy-intensity for 75% of Upstream benchmarkers is less than:

• 646 kWh, of which electricity = 560 kWh, for centres with enclosed cooled malls
• 409 kWh, of which electricity = 293 kWh, for enclosed centre (no cooling)
• 118 kWh, of which electricity = 79 kWh, for principally open schemes
• kWh of landlord-provided energy sources/m² of covered common parts/year
