Lighting: TIPS FOR SAVING ELECTRICITY
- Replace conventional incandescent light bulbs with LED or low-energy bulbs: energy usage is reduced by 80% and their useful life is much longer (between 8 and 25 times).
- For outdoor lighting, replace mercury vapour lamps with high-pressure sodium vapour, metal halide or LED lamps, as they are more efficient.
- Divide the lighting in common areas, such as transit areas, landings and corridors, into sectors. Install electronic timers or presence sensors to switch the light on and off automatically.
- Keep lamps and light fittings clean to increase their performance. Dust accumulated on the lighting systems can result in a loss of up to 10% in lighting.
Heating: TIPS FOR SAVING ON HEATING
- Remind your neighbours to keep their heating at between 19 ºC and 21 ºC and, if they use water radiators at home, to bleed them regularly, as the air accumulated inside hinders transmission of the hot water's heat.
- To prevent energy losses, it is advisable to insulate the pipes that distribute the heat and the building's façade and roof.
- If the building's installation is going to be replaced, you should bear in mind that central heating is more efficient than individual systems.
Domestic hot water: TIPS FOR SAVING DOMESTIC HOT WATER
- Encourage your neighbours to install low-consumption shower heads and aerators or flow regulators on their taps, since they reduce water consumption and, therefore, energy usage.
- Solar thermal energy is one option for complementing DHW production: it is a renewable source of energy and reduces usage and costs compared to conventional energy.
- Check the temperature of the water reaching and leaving the accumulator. This is important for detecting any possible faults in the systems. If the difference between both is greater than 20 ºC, you should contact a technician to have the production and distribution installations checked.
- Proper insulation of the pipes and the storage tanks is important to reduce energy losses in DHW installations.
Lifts and reactive energy: TIPS FOR SAVING ON LIFT USAGE AND REACTIVE ENERGY
- Ask your neighbours not to summon several lifts at once.
- If possible, install lifts equipped with selective operation mechanisms, which summon the lift which is nearest the required point.
- Certain machines, such as the electric motors of lifts or pressure pumps, consume reactive energy that is billed when it exceeds the stipulated limits. This usage can be avoided by installing capacitor banks to reduce the electricity bill and increase the machine's useful life.
