Turn energy baselines into a decision: where to act first, what to do, how to justify it (not engineering advice)
Important: This is a decision framework, not engineering advice. Engage qualified engineers and contractors for design and safety.

Pick 3–5 candidate buildings:
Most HVAC/electrification wins happen in this order:
Operations + controls
Schedules, setpoints, controls tuning
Retro-commissioning / recommissioning
Fix how systems operate
Targeted component upgrades
VFDs, controls, sensors
Major equipment replacement
High-efficiency units
Electrification
Heat pumps, electrified DHW, boiler replacement
Beginner rule: Don't jump to electrification before you know your baseline and constraints.
Reduce operating cost volatility • Reduce outage/comfort risk • Reduce emissions • Meet compliance / building standards • Prepare for tenant requirements
Done looks like: A clear definition of "success" for the project.
Focus on: high energy use intensity (EUI proxy), high gas use (if relevant), equipment at end of life, high maintenance cost and repeat issues, tenant comfort complaints, upcoming capex cycle (roof, TI, major renovation).
Minimum: 12 months electricity kWh (by billing period), 12 months fuel use (if you control fuel), equipment age/type and major constraints, major maintenance pain points. Optional: peak demand charges (kW), electrical capacity constraints, incentive opportunities.
Choose a "low regret" and a "transformational" option. Example: Path A: controls + retro-commissioning + targeted upgrades. Path B: equipment replacement + heat pumps + electrified DHW (where feasible).
Use: capex estimate range (low/base/high), savings estimate range (low/base/high), risk score (operational disruption, tenant impact, electrical capacity, permitting).
Most teams should pilot first: 1–3 buildings, clear measurement plan, clear learning agenda.

HVAC Upgrade / Electrification Decision Memo Building(s): Objective(s): Current pain: - energy cost volatility: - maintenance issues: - comfort risk: Baseline inputs: - electricity (kWh, last 12 months): - fuel (if applicable): - key equipment and age: Options considered: Option A (low regret): - scope: - capex range: - savings range: - risks: Option B (transformational): - scope: - capex range: - savings range: - risks: Recommendation: [ ] Pilot [ ] Scale Why: Measurement plan (M&V): - what we will measure: - data sources: - timeline: Decision needed: - budget approval: - pilot timeline: - next steps and owners:
M&V Starter Plan Baseline period: Data sources (utility bills, submetering, BMS): Normalization approach (weather/occupancy if used): KPIs: - kWh change - fuel use change - comfort complaints (count) - maintenance tickets (count) Cadence: - monthly review for 6–12 months
Measured kWh and/or fuel reductions
vs baseline
Reduced comfort complaints
and emergency calls
Reduced repeat repairs
lower maintenance burden
Documented learning from pilot
that improves scale decisions
Assumptions: You can access utility data and basic equipment info.
Where this can fail: If constraints (electrical capacity, tenant access, permitting) are not identified early.
