Have you heard of the concept of almost zero or no consumption building do you think are the buildings of the future or that it is nothing more than a simple trend? Today, in the designable blog, we talk about this new construction.

Near-zero energy consumption buildings (CCGs) are trying to make more of a new trend in construction. It’s the new sustainable commitment to energy savings in a sector with a high consumption of energy, such as the construction sector. On the basis that in Europe the Energy consumption accounts for 40% of total consumption,we are faced with the situation of taking the necessary energy measures to reduce this energy consumption and with them the emissions they generate.

Do you think that in the future it is possible to build a building that achieves zero or near zero energy consumption and is not polluting? The truth is that this type of building should not be the construction of the future but should already be the construction of the present, even if from 1 January 2021 European citizens will be able to acquire such homes. Would you like to live in a zero-consumption building?

Features of a building with almost zero consumption.

The concept of near-zero consumption building (ECCN) is related first of all to efficient construction and second to zero or very low energy consumption.

A zero-consumption building is one that has a very low energy demand and that manages to have a high energy efficiency with a low consumption or as its name indicates, zero.

How can we get a house to be zero-consumption? We assume that this type of construction does not have to be the same, in terms of the structure of the building, in all buildings of zero consumption but based on characteristics. For example, the first thing we need to take into account are the thermal insulation of the facades or roofs of the building. Good insulation will reduce the energy in the building and achieve greater comfort and quality inside.

The use of heating or air conditioning are the big responsible for the energy spikes in the buildings and with it the expense that it entails for the people who live there, that is why it is important to have an efficient thermal insulation.

Another important feature in almost zero consumption buildings, is ventilation, indoor air quality and humidity,this will be achieved with maximum energy efficiency.

Another feature of an ECCN is that we must always promote and prioritize natural lighting in all rooms of a home. Artificial lighting is a very high expense to the energy of a building. A very interesting option is, to install home automation systems,since these have the ability to regulate the lighting according to the needs of each one.

We should also take into account some characteristics such as orientation, sunor, or the influence of winds. A building adapted to its environment will provide some comfort parameters and thus consume less energy.

Did you know that from 1 January 2021 European citizens will be able to buy almost zero consumer properties. The European Building Energy Efficiency Directive 2010/31/EU has determined that by 31 December 2020 all newly built buildings will have to be almost zero-consumer buildings.

What regulations govern these buildings?

In Europe the regulations governing it are the European Directive 2010/31/EU and in Spain, DB HE of the Technical Building Code.

Did you know that in designable buildings we use aerothermia and photovoltaic plates with the aim of reducing energy consumption in buildings and making designable buildings almost zero consumption buildings? For example, aerothermal are state-of-the-art heat pumps designed to provide the building with cooling in summer and heating in winter. Also with aerothermia we also manage to generate hot water. And the photovoltaic plates, to get electricity.
