Top Tips for the Hotel and Leisure Sector
The hotel and leisure sector is diverse, but despite the diversity, there are several common areas where energy is wasted.
- Heating can account for 60% of your total energy costs.
- Turn it down – Lowering set points by just 1°C can potentially reduce your annual heating bill by up to 8%, so reduce the temperature on the thermostat down to the minimum comfortable level.
- Replace inefficient boilers – In many cases even higher efficiency boilers can be specified and you can gain better savings from a more energy efficient heating system.
- Install de-stratification fans -In commercial or industrial buildings with warm air heaters and high ceilings, de-stratification fans can reduce energy use by 20% by blowing warm air down to ground level where it’s needed.
- Good ventilation is essential – it gives you fresh air and also helps protect a building against damp and condensation. Unnecessary ventilation can waste energy and cost you a lot of money. For example, ventilation accounts for around 30% of heat loss in most commercial buildings (an estimated 25% in industrial buildings).
- Fans – Variable speed fans can slow down when ventilation demands decrease. This will save money on electricity as well as reducing heating/cooling costs. See Motors and Drives for more
- Time settings – Make sure fans aren’t running when they’re not required. This not only wastes energy, but also removes heat from the building.
- Air conditioning can use a huge amount of energy. In fact, air conditioning can increase a building’s energy consumption and associated carbon emissions by up to 100%.
- Even though air conditioning can use lots of energy, lots of organisations choose to use it – not least because of the extra heat generated by increasing use of IT equipment.
- Temperature control – Make sure your air conditioning doesn’t operate below 24°C. Keep a temperature gap (known as a ‘deadband’) between your heating and air conditioning control temperatures.
- Free cooling coils – Free cooling coils use the outside air as a source of cooling for air conditioning systems (when it’s cool enough). This saves money because you won’t need to use as much energy to produce cooling for the air conditioning system.
- With the UK’s temperate climate, free cooling coils can produce big savings.
On average, 25% of an organisation’s electricity costs come from lighting.
Ways to improve your organisation’s lighting include:
- Occupancy sensors: By dimming or switching off lighting when there is nobody in a room occupancy sensors can reduce electricity use by 30%.
- Daylight sensors: Adjusting the artificial lighting according to the amount of natural light in a room using daylight sensors or photocells can reduce electricity use by up to 40%.
- Maintenance plan: By regularly cleaning windows and skylights you can reduce the need for artificial light. Cleaning the fixtures that contain lamps, known as luminaires, will improve their performance.
- Get buy-in for energy saving across all levels of the company, from appointing an energy manager and monitoring energy use, to developing an action plan and training staff.
- Organising roles and responsibilities and ensuring there are sufficient resources available.
- Compliance with energy and climate change regulations is required of businesses and the public sector.
- Investment in projects will be needed to take full advantage of cost-effective energy efficiency opportunities.
- Procurement of buildings, equipment and services should take due account of the implications for energy efficiency and energy related costs.
