Advances In Regulations To Promote Energy Efficiency
Reduce The Energy Demand and Consumption
The Update Of The Nearly Zero Energy Building ConceptAdvocating a clear and concise definition of a Near Zero Energy Building is part of the new regulation. It refers to those homes that completely satisfy their energy needs by using connected renewable energy sources. The building’s air conditioning must be built under the protection of passive architecture. The idea is to adapt the building to the environment in order to use it in its favour and not be affected by temperature changes, based on the distribution, design, orientation and materials. Within the building’s air-conditioning systems is ventilation, which must include efficient and sustainable systems that help to renew the air.
New CTE For Sustainable ConstructionThe new regulation puts the focus on the current waste of energy consumption. The measures implemented will reduce the energy demand in future buildings without affecting the health of the inhabitants.
Ventilated facades, wind energy, installation of photovoltaic panels, good thermal insulation, geothermal energy or the best orientation, all these issues to be addressed are part of this great advance that is about to come. Meanwhile, these are the advances that are part of the new CTE regulations:
- Non-renewable energy use is reduced, limiting energy consumption by 38% in multi-family buildings and 60% in single-family buildings in areas most affected by winter.
- After the regulation comes into force, 60% of the primary energy of a building must be renewable. In the same way, the final energy consumption should be reduced by using, for example, cooling and heating generators.
- The requirements for climate zone renovations are made more stringent.
- The use of renewable sources such as solar, thermal or photovoltaic is no longer a priority in order to promote the use of new sources that are affordable and easily adaptable to the particularities of each area.
- Primary energy consumption continues to be the main indicator of energy efficiency with one exception, the introduction of Total Primary Energy Consumption which covers, not only cooling and heating levels, but all the energy needs of the building.
- The new parameter Global Heat Transmission Limit Coefficient makes its presence felt in order to assess the building in terms of solar control, air permeability and heat transmission.
