Hotel Energy Management
Energy is typically the second-largest controllable cost in a hotel. Most of it is not wasted through system failure. It is wasted through poor scheduling, unoccupied rooms being conditioned, controls that no longer match how the building is used, and high overnight baseload that nobody is tracking.
Where Hotel Energy Spend Goes to Waste
The monthly energy bill tells you what a hotel spent. It does not tell you where the money went. In most hotels, the highest-cost waste sources are invisible on a standard utility invoice: empty rooms being heated or cooled overnight, HVAC systems running on schedules that were set years ago, hot water cylinders losing heat through poorly insulated pipe runs, and lighting left on in back-of-house and meeting areas that are empty for hours at a time.
Before spending on new plant, controls technology or retrofit, the right starting point is a clear picture of where the waste is occurring and which fixes are commercially worth pursuing. Typically 15 to 30 percent of annual energy spend can be recovered through practical changes. For a hotel spending £200,000 per year on energy, that is a significant margin improvement.
The Problem
- Guest rooms conditioned whether occupied or not
- HVAC running to fixed schedules, not actual occupancy
- High overnight baseload with no explanation
- Hot water losses through long dead-leg pipe runs
- No sub-metering to identify which areas are driving costs
- EPC ratings that are restricting asset financing or sale
The Commercial Case
- Energy is typically the second-largest controllable cost after labour
- MEES regulations are tightening: EPC B is the proposed minimum by 2030
- Poor EPC ratings are increasingly flagged by lenders and investors
- Booking platforms and corporate travel buyers are requesting ESG data
- Unmanaged energy costs compound during periods of low occupancy
What an Evolution NetZero Hotel Energy Review Covers
HVAC and Guest Room Controls
Review of heating, cooling and ventilation scheduling, zoning, occupancy linking and controls quality. Guest room energy management is often the highest-value area in a hotel and is worth assessing before any other investment.
Hot Water and DHW Systems
Hotels carry high hot water loads. We review cylinder temperatures, pipe insulation, dead-leg lengths and whether Legionella compliance requirements are being used as a reason to avoid sensible DHW optimisation, when in practice the two can be managed together.
Lighting and Back-of-House
Corridor lighting, back-of-house areas, plant rooms, car parks and meeting rooms often run continuously. We identify where occupancy sensing or scheduling would reduce lighting waste without affecting guest experience.
Overnight Baseload
Overnight baseload is one of the most revealing indicators of energy waste in hotels. We review what is running when the building is at minimum occupancy and identify anything that should not be.
Metering and Visibility
Without adequate sub-metering, you cannot identify which areas are driving costs or verify that changes are working. We review existing metering coverage and recommend practical improvements where visibility is poor.
EPC and Compliance Position
We review current EPC ratings against proposed MEES requirements and flag any compliance risks that should be addressed alongside energy improvements, so both are dealt with as a single programme rather than separate projects.
Frequently Asked Questions
How much can a hotel save with an energy management programme?
This depends on the current state of the building, its controls and how actively energy is being managed. In hotels where HVAC runs on fixed schedules and there is little or no sub-metering, savings of 20 to 35 percent on total energy spend are commonly achievable through a combination of controls improvements, scheduling and fabric measures. We do not guarantee a specific figure: the free desktop report gives you an indicative range for your building before any money is spent.
Will energy improvements disrupt guests or operations?
The highest-impact measures, such as occupancy-linked HVAC controls and lighting scheduling, are designed to operate with minimal disruption. Comfort standards are maintained. We sequence work to avoid unnecessary operational disruption, and site-based work is planned around occupancy levels where possible.
What is the difference between a hotel energy audit and what Evolution NetZero does?
A standard energy audit produces a report. Evolution NetZero starts with a free desktop review to identify likely waste areas, then delivers a paid on-site diagnostic that prioritises improvements by payback period and commercial impact. We are focused on what is worth doing first, in what order, and at what cost, not on producing a document for its own sake.
