In the home

The Energy Efficiency Certificate grades buildings depending on their energy consumption on a scale from A to G.

Lower the sun blinds and close curtains at night to avoid losing heat from inside.

Detect air currents from the movement of the curtains next to the sun blind boxes, and at any other point where air can come in from outside.

Collective central heating with individualised measurement and control is recommended from the energy and economic point of view.

At night, turn off the heating or reduce the temperature to 17-19ºC, except in very cold areas or buildings without insulation.

A room can be aired in 10 minutes. Heating cold air is very expensive.

Do not cover or obstruct radiators, the air needs to circulate to heat well.

Only use domestic hot water when it is necessary. Saving water = saving energy.

Rationalise water consumption. Do not leave taps running while shaving, brushing teeth, etc.

Avoid leaks and drips of hot water.

Take a shower instead of a bath. One bath is equivalent to 3 or 4 showers in terms of water consumption.

Install thermostatic taps and low-consumption shower heads.

If a bathroom of kitchen still has individual taps for hot and cold water, change them for a single mixer tap.

Remember that the water used will later be processed in a treatment plant that requires a certain amount of energy.

Domestic hot water storage tanks and pipework should be well insulated.

Thermal solar energy is ideal for storing hot water in homes. It can reduce the energy cost of heating water by up to 60%.

When you buy a home it is important to ask for information on its energy quality. Take this into account in your purchasing decision, because energy consumption has a big impact on quality of life and the family budget.

A good bioclimatic design can save up to 70% in climatization and lighting, with just a small increase in construction costs.
