Energy Saving Tips … Hotels
Long hours of operation, plus the need to keep guests comfortable, can elevate heating and lighting demands. In fact, in typical leisure and hospitality environments, energy costs are second only to labour costs in terms of ongoing expense.
- Do not overheat hot water. A temperature of 60°C is optimal: it provides comfortable hot water and is hot enough to kill legionella bacteria.
- Consider fitting spray water taps, as they use less hot water and energy.
- Make sure that leaking taps are repaired promptly.
- Ensure that pipework is well insulated.
- Avoid operating the heating and cooling systems simultaneously. This can be a common problem in hotels. Turn off heating when a temperature of 21°C has been reached. In addition, back-of-house temperatures can probably be set lower than those at front of house.
- Avoid using air conditioning for cooling until the temperature exceeds 23-24°C.
- Implement a building management system (BEMS). These systems control and monitor heating, ventilation and air conditioning, and can reduce total energy costs by 10% or more.
- Avoid overheating bedrooms and corridor areas. This is not only expensive, it can also be uncomfortable for guests; aim for 19-21°C.
- Ensure good control of your heating system. Use timer switches and thermostatic radiator valves, and check that thermostats are unaffected by draughts, sunlight, radiators and fireplaces.
- Be aware when replacing inefficient boilers that the latest Building Regulations set minimum efficiency standards for new and replacement boilers. In many cases, even higher efficiency boilers can be specified and you can gain better savings from a more energy efficient heating system.
- In high ceilinged areas (e.g. reception areas) with warm air heaters, de-stratification fans can reduce energy use by 20% by blowing warm air down to ground level where it's needed.
- Service your boiler regularly. This could help you save up to 10% on your annual heating costs.
- Ensure that pipework to bedrooms and common areas (e.g. reception) is well insulated.
- Defrost fridges regularly; check the seals on cold rooms and fridges; and keep condensers and evaporators clean.
- When replacing or buying new fridges, look for energy efficient units such as those that are A-rated. If possible, buy A++ units, as they have the lowest electrical running costs.
- Keep fridge doors closed as much as possible
- Install occupancy and daylight sensors so that your lights are only on when required.
- Use low-energy lighting. Replace tungsten GLS lamps and T12 fluorescent tubes with much more energy efficient items such as T5 tubes or compact fluorescent or LED lamps. These could help you reduce the electricity you consume for lighting by up to 80%. Furthermore, some of the newer bulb types last more than eight times longer than tungsten GLS lamps and, as they produce less heat, they will put less strain on the cooling required from your air conditioning system.

Outlook: Energy Efficiency for Business
Energy costs have a significant impact on every SME in Ireland. Reducing energy consumption saves SMEs money, and those savings go straight to the bottom line. This report analyses energy consumption, the understanding of energy bills and the appetite to undertake energy initiatives to reduce costs.
