Reduce hotel energycosts withoutcompromising comfort.
Engineering, energy intelligence and practical optimisation for hotels, resorts and leisure facilities operating around the clock.
Find where performance is lost. Protect the guest experience. Focus on what is commercially worthwhile.
Hotels never stop operating.
Bedrooms, public areas, kitchens, restaurants, pools and spas create different energy demands throughout the day. Heating, cooling, ventilation, hot water and lighting must respond without disrupting the guest experience.
When plant schedules, controls and setpoints drift away from occupancy and demand, energy costs can rise while the underlying causes remain largely invisible.
Zerith identifies practical improvements before a major replacement becomes necessary, then helps hotel teams prioritise measures that are operationally feasible and commercially worthwhile.
Why hotel energy performance is difficult to control.
Cost, comfort and operational complexity are connected. A useful assessment looks at how the whole hotel runs, not one meter or system in isolation.
01 / COSTRising operating costs
Energy price increases and inefficient operation place direct pressure on margins and room costs.
02 / COMFORTGuest expectations
Heating, cooling and hot water must support comfort, service levels and brand standards.
03 / PLANTAgeing building services
Boilers, chillers, air-handling systems and controls can outlast the strategy they were designed to follow.
04 / CONTROLFragmented controls
Local overrides, drifting sensors, refurbishments and contractor changes can leave systems working against each other.
05 / DEMANDComplex demand
Bedrooms, kitchens, leisure facilities, events and laundry create changing loads that generic assumptions miss.
Find waste in the way the hotel actually operates.
Choose a system area. Zerith combines engineering inspection, operational data and discussions with site teams to understand how each system responds to real demand.
HVAC schedules, setpoints and zones
Review how heating, cooling and ventilation schedules respond to occupancy, operating hours and the different zones across a hotel.
The useful question: are the controls serving the building’s current use?

Clear answers before the first conversation.
Start with the questions hotel teams commonly ask when reviewing energy performance, compliance and investment priorities.
Discuss your hotelCan you support ESOS and hotel decarbonisation planning?
Yes. Zerith supports energy compliance and uses engineering evidence, operational data and modelling to develop credible improvement and investment plans. Compliance findings can support broader performance and Net Zero decisions.
Will reducing energy use affect guest comfort?
The aim is to remove waste and improve control while protecting temperature, hot-water availability, air quality and the standards guests expect. Zerith assesses how systems respond to occupancy, weather and operational demand before recommending changes.
Do you work with individual hotels as well as large groups?
Yes. Zerith can investigate a single hotel’s building performance or develop a consistent approach across a wider portfolio. Scope is aligned with the number of properties, available data and the decisions the client needs to make.
How quickly can a hotel identify savings?
Timescales depend on data quality, site complexity and the measures identified. Operational issues such as schedules, setpoints or plant sequencing may be addressed relatively quickly; larger upgrades need design, commercial review and investment planning.
Can Zerith assess pools, spas, kitchens and laundry facilities?
Yes. These areas often create significant and variable energy demand. Zerith can examine associated heating, ventilation, hot-water and control strategies as part of a wider hotel assessment.
What information is useful before an initial discussion?
Useful information includes the number and type of properties, recent energy data, known comfort issues, major plant details, operating patterns and any planned refurbishment or capital programme. A first discussion can still proceed if some information is unavailable.
