What this guide helps you evaluate
commercial property, facilities and project teams evaluating capital projects and building-lifecycle services where scope control, asset condition and transition economics are material. This buyer guide helps organize a decision about energy retrofit performance contract.
Prepared by the PROFENG Editorial & Engineering Team. This page is designed to help you compare the moving parts, organize due diligence and ask better questions before you commit money, sign a contract or change an operating process.
Define the business outcome, decision owner, expected term and the evidence needed to validate energy baseline and savings guarantee.
Normalize energy baseline and savings guarantee, equipment scope measurement and verification and financing service terms and performance remedies before comparing proposals or internal options.
Keep assumptions separate from verified facts and record the source, date and owner for material requirements.
Decide what is worth buying before comparing vendors
A buyer guide should narrow the market before detailed scoring begins. Define the operating outcome, minimum acceptable capability and evidence threshold first; only then compare suppliers that can satisfy that baseline.
- Separate mandatory requirements from preferences and future nice-to-haves.
- Ask for proof of fit using relevant references, demonstrations or documented operating evidence.
- Compare full-term ownership cost, internal workload and exit effort rather than headline price alone.
- Reject options that cannot meet a non-negotiable requirement even when their feature list is broader.
Decision gate: move an option into the shortlist only when its fit, evidence, ownership model and likely total cost are sufficiently clear to justify deeper due diligence.
What to compare first
- energy baseline and savings guarantee
- equipment scope measurement and verification
- financing service terms and performance remedies
- asset and project scope
- delivery responsibility and acceptance criteria
- capital cost, operating impact and lifecycle evidence
Step-by-step process
- 01
Define the business outcome, owner, budget range and non-negotiable requirements before vendor outreach.
- 02
Shortlist options using evidence for energy baseline and savings guarantee, equipment scope measurement and verification, financing service terms and performance remedies rather than brand familiarity alone.
- 03
Request comparable proposals using the same scope, term, volume and implementation assumptions.
- 04
Validate references, support responsibilities, renewal economics and exit feasibility.
- 05
Document the final selection rationale, exceptions, approval conditions and evidence.
Common mistakes and risk checks
- approving projects without a measured baseline
- underestimating landlord tenant or operational interfaces
- failing to define acceptance, warranty and handover evidence
- Treating a buyer guide as a substitute for signed agreements, current official rules or qualified professional review.
Documents and evidence to collect
- asset condition and building inventory
- lease or project requirements
- budget and baseline operating data
- provider proposal and project schedule
Questions to ask before approval
- How is energy baseline and savings guarantee defined, measured and evidenced?
- What changes if equipment scope measurement and verification is higher or lower than the base case?
- Which fees, exclusions, implementation tasks or operating duties sit outside financing service terms and performance remedies?
