A new hotel can have a completed electrical design before it has a representative energy-use history. The connection schedule may identify equipment capacity, while a supplier asks for monthly quantities and operating shape. Translating between those records requires explicit assumptions about operation rather than a single multiplication by room count.
The procurement hub addresses the commercial purchase. This guide concentrates on the forecast a bidder can understand: its engineering basis, uncertain phases, units, and planned replacement with observed evidence.
What is the forecast intended to support?
State whether the estimate supports an early supplier discussion, a tariff inquiry, a proposed commercial offer, or a later operating budget. These uses can need different detail and confidence. An estimate suitable for a preliminary comparison may not be ready for a final volume commitment.
Identify the account and time boundary. Include the permanent hotel service points expected in the quote and distinguish temporary construction accounts. List electricity and gas separately; a project can shift consumption between fuels without changing the equipment function being served.
The new-build situation guide handles service milestones and opening responsibilities. The forecast workbook should connect to that project record without treating physical energization and supplier acceptance as the same approval.
Which engineering records belong behind the estimate?
Ask the responsible professionals for an approved equipment summary, fuel connections, operating sequence, expected hours, and opening phases. Identify differences between design and installed scope. Record the source and date for significant assumptions rather than attributing them vaguely to the construction team.
EPA’s lodging resource identifies guest and support-space uses that matter to hotel energy. It provides useful boundary prompts, not an engineering forecast for this building. Kitchens, laundry, common areas, and central equipment should not disappear from an estimate because rooms are the easiest inventory to count.
Include standby or continuing loads where the responsible engineer identifies them. Do not prescribe operating settings or disable required systems through a purchasing worksheet. The forecast records approved operation; qualified staff determine safe and applicable technical requirements.
| Assumption | Supporting record | Quantity and timing | Revision trigger |
|---|---|---|---|
| Commissioning operation | Testing schedule and equipment scope | Fuel, power, hours and phase | Changed testing plan |
| Guestroom ramp | Approved available-room schedule | Phase-specific activity assumption | Opening delay or inventory change |
| Support services | Kitchen, laundry and plant schedules | Separate load and operating period | Installed scope or sequence change |
| Observed replacement data | Validated meter export | Dates, units and coverage | Representative operation available |
How do kW and kWh enter the workbook?
EIA’s electricity measurement explanation distinguishes power from energy. A kW assumption describes a rate of use; kWh depends on the period and operation. A design load cannot be labeled annual consumption without the missing time and operating assumptions.
Preserve the units in each calculation. If intervals are supplied as energy, identify their duration before interpreting average power. If an equipment schedule states rated capacity, label any assumed operating fraction rather than presenting the reduced figure as an observed demand.
The workbook should not equate the sum of equipment ratings with the actual peak automatically. Simultaneous operation, controls, and measured evidence matter. Engineering should explain any diversity or coincidence assumptions instead of allowing a bidder to infer them from an unexplained total.
How should the opening phases be represented?
Separate commissioning, partial guest opening, and stabilized operation where they apply. Describe available rooms, opened amenities, retained construction work, and the expected calendar. A flat annual allocation can conceal months with very different equipment and activity.
Record delayed-opening alternatives only where they help the actual decision. A forecast can show a base schedule and a defined delay scenario without predicting which will occur. Keep approved milestones distinct from planning dates still awaiting confirmation.
The construction procurement guide connects phase changes with commercial questions. Ask the supplier how its actual agreement treats the described start and consumption uncertainty. A fixed energy component alone does not settle volume consequences or permitted changes.
What does a transparent assumed calculation show?
Assume, solely for teaching the unit method, one equipment group draws an average 20 kW for four hours per day during a thirty-day phase. Its assumed energy is 20 × 4 × 30 = 2,400 kWh. These are invented illustrative inputs, not a hotel equipment prediction or measured result.
If the same assumed group operates eight hours per day, the calculated energy becomes 4,800 kWh. Its assumed operating power remains 20 kW in both examples. The calculation demonstrates why operating hours change energy without automatically doubling an equipment capacity or a tariff demand.
A real workbook would need additional groups, actual control behavior, and evidence of coincident operation. Do not add this example’s quantity to a project quote. The example explains the dimensions that the project engineer and supplier should make explicit.
What uncertainty should the provider see?
Mark missing information at the affected assumption. This could include an unconfirmed equipment selection, unknown operating schedule, pending service identifier, or a delayed amenity opening. Avoid burying all uncertainty in a generic disclaimer beneath a precise annual total.
Ask the bidder what further data its product requires and which assumptions it adopted. Preserve the response with the offer. A provider’s willingness to issue a preliminary indication does not prove that the forecast meets every final credit, enrollment, or volume requirement.
Use the quote-input guide to assemble the account and authority evidence. Present the engineering forecast as a clearly identified input rather than relabeling it as historical consumption.
How should tariff implications be investigated?
DOE’s utility rate evaluation guidance explains why energy, demand, and other components need the relevant load and tariff. For a new hotel, confirm the proposed schedule and eligibility with the serving utility.
A forecast showing an annual kWh total alone does not establish monthly demand, time-of-use quantities, or the best available tariff. Keep account class and utility charges outside the supplier product visible. Ask how temporary and permanent services differ where both exist.
Review later changes to major electrical systems, charging, laundry, or cooking with the appropriate technical and utility contacts. An updated energy estimate should not imply that a different connection or tariff has already been approved.
How does observed operation replace the assumptions?
DOE’s M&V Guidelines version 5.0 supports documented baselines, measurement boundaries, and operating assumptions in its project context. Use those principles carefully; the document is not a new-hotel supplier forecast standard.
Plan a review when representative meter data becomes available. Check service dates, units, missing intervals, unusual commissioning operation, and the amenities actually open. Compare the observations with the relevant forecast phase instead of treating an early construction month as stabilized performance.
Preserve old and new versions, with a short explanation of quantity, timing, and boundary changes. That record helps ownership and the provider understand whether a difference came from corrected assumptions, different operation, or a changed project scope.
What needs approval before the forecast supports a purchase?
- Identify the account, fuel, period and intended forecast use.
- Obtain the approved engineering and opening-phase records.
- Keep capacity, power and energy quantities distinct.
- Label operating hours, coincidence and other assumptions.
- Resolve tariff and supplier requirements for the actual accounts.
- Document commercial treatment of remaining uncertainty.
- Assign the observed-data review and version owner.
Include broker compensation in any price comparison using the forecast: payer, calculation, unit basis, and embedded or separate treatment. An assumed consumption figure can affect modeled compensation as well as supply cost. Keep both assumptions visible until the actual commercial agreement and approved account evidence support the purchase.
