Nearly Zero Consumption Buildings

Nearly Zero-Energy Building

Sustainable facade in Antarctica

What is a nearly zero-energy Building?

Nearly zero-energy buildings are buildings that have a very high level of energy efficiency, thus requiring little or no energy to operate, which in turn allows them to source their energy needs solely through on-site renewable energy sources.

This European Directive 2010/31/EU establishes the obligatory nature for the construction of this type of buildings.  It determines that as of December 31, 2018 all new public buildings will be nearly zero-energy buildings.  These buildings save energy because their construction principles as well as the systems they use are aimed at reducing energy demand.

From Spain to Antarctica with warmth

Recently, a Spanish construction Company called ACR Group financed by the Government of Navarre and with the support of the European Regional Development Fund (ERDF), sent a prototype of a sustainable façade to Antarctica,

ACR group and the University of Navarra are responsible for sending a prototype of industrialized facade to test an innovative heating and cooling system.

In 2010, the University began a research focused on the benefits of thermoelectricity and in 2016, the ACR Group joined the project.

The research is part of the “Green Campus” project of the Horizon 2020 initiative of the University of Navarra. It is also part of the philosophy of the ACR Group, which is committed to innovation as means of improving and optimising its operations.

What does it offer?

This is the first time that a prototype of this type has been tested in such a challenging environment as the one present in Antarctica. For this reason, the Spanish Antarctic Base Gabriel de Castilla has been in charge of collecting information on the functioning of the façade over the last few months.

One single system combines both heating and cooling functions, which eliminates CO2 emissions. In this way, emissions of fossil fuels and cooling fluids would be avoided.

The sustainable façade prototype sent to Antarctica had to be specifally adapted for the transportation and installation challenges presented.

Being able to test the system in Antarctica represents a great opportunity, as it provides robust scientific basis and testing for new technology, which would be difficult to replicate in any other type of testing, but also because it would represent an important recognition of the overall project.
