Climate change is an indisputable reality. We are already noticing its consequences and if we do not reduce greenhouse gas emissions even more, impacts will become progressively deeper. And one of the most effective ways of fulfilling this is by supporting energy efficiency at every level, including buildings, since more than 40% of greenhouse gas emissions in Europe originate in their energy consumption.

We are not fully aware of building energy consumption. Heating, air conditioning, domestic hot water, ventilation, lighting… Being aware of which the main areas of energy consumption are and which of them can be improved are key aspects in order to increase energy efficiency and reduce its contribution to climate change.

How can such energy consumption be reduced in a building? There are many ways to control it, but there is a key element that has a highly valuable impact: access doors. Having an automatic door makes the difference between an energetically efficient building and one that is not. An automatic door, thermally optimised, properly insulated and equipped with intelligent automation (with efficient opening and closing cycles), entails tangible energy conservation throughout its whole life cycle. Automatic closing prevents doors from staying open unintentionally. This entails an important reduction in the loss of temperature control systems in the facilities, and up to 70% of air conditioning and heating costs can be saved, depending on the type of automatic door that is chosen.

The solutions that can be applied regarding automatic doors, such as the possibility of adjusting the movement of their opening and closing systems, depending on the existing people circulation, or presence sensors which activate the opening only when there are people, enable to optimise temperature control systems and keep the interior of the building at a stable temperature. But moreover, the thermal insulation system offered by automatic doors avoids air leaks and keeps temperature stable for a longer period of time, and therefore, consumption decreases. And contrary to popular belief, the engine of these doors makes use of almost no energy.

It is worth mentioning that the thermal insulation of buildings is one of the most efficient measures to confront climate change. It improves energy efficiency as well as it contributes to its sustainability. As reported by the Institute for Diversification and Energy Conservation (IDEA, according to its initials in Spanish), small enhancements in thermal insulation can entail an energy and economic savings up to 30% in heating and air conditioning. For instance, insulation systems of interior and exterior walls, envelopes or the installation of double glazed windows or with thermal bridge breaking systems, in addition to automatic doors, help reduce energy consumption. Besides, supporting the installation of solar façades, which promote in turn self-consumption and act as a thermal insulation material, makes energy consumption needs lessen.

Not to mention that automatic doors are a highly helpful element in order to comply with current regulations, which head towards energy efficiency to contribute to environmental protection, a legislation that will become harder by 2020. At the end of that year, the entry into force of a European Directive (2010/731/EU) is planned, and it will force newly built constructions to reduce their levels of energy consumption. New constructions will have to be built according to a set of indicators which optimise the efficiency of the energy consumed and rely on sustainable energy sources (such as solar, geothermal or biomass) and on the environment. At the core of this directive, there are measures on water heating, lighting control and heating and air conditioning control. Relative to this point, the installation of automatic doors in building accesses or to mark out different areas will help control HVAC systems and reduce energy consumption.

Replacing a traditional door with an automatic door is an easy and simple way of contributing to confront climate change. It is not only a very profitable investment, since it entails high cost saving, but also the reduction of CO2 emissions and the contribution to environmental preservation make this decision an easy one to take.

In Manusa, there are different effective solutions that can be customised. Manusa’s automatic doors offer design, functionality and the quality guarantee of the market-leading company, both at the national and international level. It provides solutions for all types of buildings, whether they are hotels, offices, hospitals or the public transportation sector. By these means, the energy efficiency of the building will be improved, as well as comfort and security in the facilities guaranteed.
