Energy Management in Commercial Real Estate

How multi-let buildings use energy and who pays for it, the benchmarks and ratings the sector runs on, the landlord regulation that now has teeth, and the retrofit and controls opportunities that survive the split incentive: capped with a full office-building energy audit.

01The Commercial Building & Where Energy Goes

  1. ▶The Commercial Real Estate LandscapeWho owns, manages and occupies UK commercial buildings, which meters belong to whom, and why the service charge shapes every energy decision.10 min
  2. ▶Where the Energy Goes in an Office BuildingHVAC, lighting, small power and the base load that never switches off: the load profile of a multi-let office, and what drives each slice.10 min
  3. ▶The Split Incentive & Green LeasesWhy the party paying for efficiency is rarely the one who saves, and the lease clauses, service-charge mechanisms and data-sharing terms that fix it.10 min
  4. ▶Fundamentals CheckQuiz on the CRE landscape, office energy breakdown and the split incentive.5 min

02Benchmarks, Ratings & the Performance Gap

  1. ▶Benchmarking: kWh per Square MetreREEB and CIBSE benchmarks for offices, the NLA vs GIA trap, and how to tell whether a building is genuinely good or just quietly typical.10 min
  2. ▶EPCs, DECs and NABERS UKAsset ratings versus operational ratings, the performance gap between them, and why the sector is shifting to measured, in-use performance.10 min
  3. ▶Sub-Metering & Tenant BillingLandlord and tenant supplies, the sub-meter hierarchy a multi-let building needs, and apportioning energy fairly through the service charge.9 min
  4. ▶Benchmarks & Ratings CheckQuiz on office benchmarks, EPCs vs DECs vs NABERS, and sub-metering.5 min

03Regulation & Compliance for Landlords

  1. ▶MEES: The Minimum Standards That BiteThe EPC E floor for lettings, the June 2026 shift to EPC B by 2031 for larger buildings, exemptions, enforcement and what a prudent landlord does now.11 min
  2. ▶ESOS, SECR & TM44 for Property CompaniesWhich reporting and inspection schemes catch a property business, how landlord and tenant consumption split across them, and the TM44 air-conditioning inspection cycle.10 min
  3. ▶Heat Networks: The New Regulated UtilityFrom January 2026 Ofgem regulates heat networks, and a landlord selling heat to tenants is now an energy supplier with obligations to match.10 min
  4. ▶Regulation & Compliance CheckQuiz on MEES, ESOS/SECR/TM44 and the new heat-network regime.5 min

04Efficiency Opportunities in Practice

  1. ▶Out-of-Hours Waste & BMS Quick WinsA building is empty two-thirds of its hours: reading the overnight base load, and the scheduling, setpoint and dead-band fixes that cost nothing.10 min
  2. ▶Retrofit Planning: Lighting, Plant & Heat PumpsSequencing LED, chiller and boiler replacements around lease events and MEES deadlines, and when a heat-pump conversion stacks up.10 min
  3. ▶Hands-On: Two Quick DiagnosticsTwo short office call-outs: a building burning £50,000 a year out of hours, and an air-handling unit heating and cooling the same air. Calculate, diagnose and prescribe the fix.12 min
  4. ▶Efficiency in Practice CheckQuiz on out-of-hours waste, BMS quick wins and retrofit sequencing.5 min

05Capstone Project

  1. ▶Capstone: Audit an Office BuildingA full, staged energy audit of a fictional multi-let office: scope it around the landlord boundary, walk the plant rooms, normalise a year of data, and rank what you find.35 min
