Next year will be crucial for energy consumption, partly due to the regulatory changes of Nearly Zero Energy Buildings. We explain the challenges of energy efficiency in 2020.

New models of green housing are the future of building. But how much energy can a sustainable house save?

Nearly Zero Energy Building is almost a reality, and current energy certificates can be a great guide to meet its requirements.

Today we can rely on energy certificates to know if a home meets the energy efficiency requirements. One of the most useful is the LEED certification.

Wind ventilation is a system that can remove heat from rooms in summer in a simple and ecological way.

Are sustainable houses the homes of the future? Or are they already a reality? We detail everything about this ecological way of life at home.

With the high temperatures, energy consumption also skyrockets. Is it possible to improve the electricity bill in summer? Yes, with these energy saving measures.

Thermal solar energy can help us heat homes and provide supplies in a totally sustainable and cost-free way.

One of the most common mechanisms to save energy in new buildings is sanitary hot water (ACS), which allows heating water with the rays of the sun.

In the hottest months, it is necessary to achieve good air renewal. And in summer we can lower the temperatures by eliminating hot air.
