Energy Spend & Data

Understanding your current energy baseline helps identify where to look first.

Approximate monthly energy spend — electricity and gas combined *

An estimate is fine. Used only to scale indicative savings figures.

Do you receive separate electricity and gas bills?

Yes — separate electricity and gas Electricity only Gas only Not sure

Is half-hourly electricity consumption data available for your building?

Yes — we can access it No Not sure

Do you know your total energy spend for the last 12 months?

Yes — I have the figures Approximately No

Do you have an energy monitoring dashboard or real-time display?

Yes — we monitor in real time Partially — some visibility No Not sure

What data can you provide? (tick all that apply)

Electricity bills Gas bills Half-hourly data Metre photos

Upload energy bills or data files *

Energy contract renewal date (optional) Knowing when your contracts are up helps us time our recommendations.

Energy Generation

Understanding whether your property generates its own energy helps identify missed opportunities and the true net cost of your energy supply.

Does the property generate any of its own electricity or heat?

Yes No Not yet — but it is planned Not sure

What types of generation are installed? (select all that apply)

Solar PV (electricity) Solar thermal (hot water) Combined Heat & Power (CHP) Wind turbine Battery storage Other

Estimated annual generation output (if applicable) Enter the total kilowatts per annum produced. Leave blank if unknown or not applicable.

Electricity generated

kWh/yr

Heat generated

kWh/yr

Is generation output monitored and metered separately from the grid supply?

Yes No Not sure Not applicable

Are you currently exporting excess electricity to the grid?

Yes — exporting under SEG or similar No Not sure Not applicable — no generation

Are there plans to install or expand on-site renewable generation in the next 3 years?

Yes — funded and in progress Yes — planned but not yet funded Under consideration No current plans

Heating & Hot Water

Heating and hot water are often the single largest source of energy waste in hotels and commercial buildings.

Primary heating fuel

Age of main heating system / boilers

Under 5 years 5–10 years 10–15 years Over 15 years Not sure

Heating zone controls and scheduling

Controlled via BMS — zoned and scheduled Basic time clocks and thermostats Limited — minimal zoning or scheduling No controls or scheduling Not sure

Are pipework and hot water cylinders insulated?

Yes — fully insulated Partially insulated No / minimal Not sure

Known heating system issues

No known issues Minor issues — being managed Significant issues System is ageing — due for review or replacement

Cooling & Air Conditioning

Cooling systems are a common source of unmanaged energy cost, particularly in buildings without occupancy-responsive controls.

Does your building have air conditioning or mechanical cooling?

Yes — central system Yes — individual split units Both central and splits No mechanical cooling Not sure

Approximate age of main cooling equipment

Under 5 years 5–10 years 10–15 years Over 15 years Not sure Not applicable

When was cooling equipment last professionally serviced?

Within the last 12 months 1–2 years ago Over 2 years ago Not sure Not applicable

Are there complaints about areas being too hot or too cold?

Rarely or never Occasionally Frequently Yes — a known and ongoing issue

Guestroom Energy Management

In hotels, heating and cooling unoccupied rooms is often the single largest area of avoidable energy waste.

What type of temperature controls do guests have in their rooms?

Full VRF or fan-coil with in-room thermostat Wall thermostat connected to central plant Simple dial or knob controls No in-room temperature control

What happens to heating or cooling in unoccupied rooms?

Managed automatically by a guestroom management or BMS system Managed by staff procedures (e.g. housekeeping turns off) Continues running unchanged — no automatic management Not sure

Is there an occupancy-based energy management system in guestrooms?

Yes — fully deployed across all rooms Yes — deployed in some rooms only No

These questions have been adapted for education settings.

How are classrooms and teaching spaces managed when unoccupied?

Automatically — via BMS or occupancy sensors Timed schedules only Manually by staff Not actively managed Not sure

Are heating and cooling setback profiles applied during holidays and weekends?

Yes — setback in place for holidays and weekends Partially — some setback applied No — system runs at similar levels year-round Not sure

Guestroom energy management applies primarily to hotels and serviced apartments. The questions below have been adapted for your property type.

How are zones or spaces managed when not in use?

Automatically — via BMS or scheduled controls Manually by staff or occupants Not actively managed Not sure

Leisure Facilities

Swimming pools, spas and steam rooms are among the highest energy consumers in any hospitality property. How they are heated and controlled has a major impact on total energy cost.

Does the property have a swimming pool?

Yes — indoor pool Yes — outdoor pool Yes — both indoor and outdoor No

How is pool water heated?

Gas boiler Heat pump (air source or ground source) Solar thermal with backup Electric immersion CHP / combined heat and power Not sure Not applicable — no pool

Are pool pumps variable speed or demand-controlled?

Yes — variable speed drives fitted No — fixed speed Not sure Not applicable

Is there heat recovery on pool hall ventilation?

Yes No Not sure Not applicable

Does the property have a spa, steam room, sauna or hot tub?

Yes No

How are spa and steam facilities heated?

Dedicated boiler Shared with main building plant Electric Heat pump Not sure Not applicable

Are leisure facilities (pool, spa, steam) on a timed or occupancy-based schedule?

Yes — fully scheduled and automated Partially scheduled Manual only — staff controlled No scheduling in place Not applicable

Ventilation

Ventilation without heat recovery can account for significant energy loss, particularly in buildings with high air-change rates.

What type of ventilation does your building use?

Mechanical ventilation with heat recovery (MVHR) Mechanical ventilation — no heat recovery Natural ventilation only (openable windows) Mixed — both mechanical and natural Not sure

Is ventilation demand-controlled (adjusts based on occupancy or CO₂ levels)?

Yes Partially No — runs at a fixed rate Not sure

When were ventilation units or AHUs last serviced?

Within the last 12 months 1–3 years ago Over 3 years ago Not sure Not applicable

Hot Water & Water Efficiency

Hot water generation is one of the most commonly overlooked areas in energy reviews.

Primary domestic hot water system

Central gas boiler and calorifier Combi boilers (gas) Electric immersion or point-of-use heaters Heat pump water heating Solar thermal (with backup) Not sure

Is there sub-metering for hot water or overall water consumption?

Yes No Not sure

Are flow restrictors or aerators fitted to taps and showers?

Yes — fitted throughout In some areas No Not sure

Building Controls & Monitoring

The presence and quality of building controls is one of the strongest indicators of where energy waste is going undetected.

Do you have a Building Management System (BMS)?

Yes — full BMS covering HVAC, heating and more Yes — basic controls and some automation No Not sure

When were building controls last reviewed, recommissioned or updated?

Within the last 2 years 2–5 years ago Over 5 years ago Never / not sure

Do you have sub-metering for individual systems (HVAC, lighting, plant)?

Yes — comprehensive sub-metering Yes — in some areas No Not sure

Do you use any energy management software or monitoring platform?

Yes No Not sure

ESG & Reporting

Understanding your current reporting position helps identify whether energy improvements can generate ESG and stakeholder value alongside cost savings.

Do you currently report on energy consumption or carbon emissions?

Yes — formal reporting in place Yes — informally, but not structured Working towards it No

Do you have formal ESG or sustainability targets?

Yes — board-approved targets Yes — operational targets in place Planning to set targets No targets currently

Key stakeholders for energy and ESG reporting (select all that apply)

Owners or investors Procurement or supply chain Guests or customers Board or leadership team None currently
