Energy savings

 In Energy savings

In 2013, the Fifth Assessment Report (AR5) of the Intergovernmental Experts on Climate Change (IPCC) concluded that “it is extremely probable that human influence has been the dominant cause of observed warming since the middle of the 20th century”. The greatest human influence has been the emission of greenhouse gases such as carbon dioxide, methane and nitrogen oxides.

Directive 2012/27/EU of the European Parliament and of the Council includes the change/adaptation of user behaviour in the definition of improving energy efficiency.

The Member States of the European Union are adapting their building regulations to this transversal need for maximum savings and energy efficiency in building. It will be a common language for 508 million Europeans. 2018-2020 is the key biennium for this harmonisation.

As users, we internalize practices in our daily lives, we consider them valid and, also, we can change them when we believe it is better to do so.

The inmmediate purpose of the study is to determine which of these practices are significant in relation to the identification of the Almost Zero Consumption Building (ECCN) by the current user, who is mostly unaware of its existence.

To understand qualitatively how this adaptation of the user to the new habits of efficient energy consumption can be happening among us.

The starting hypothesis is considered to be the ECCN designed and built according to the Standard PASSIVEHAUS (PH).
Passivehaus buildings are a sub-typology of ECCN2. They are more efficient than the named energy- efficient building or conventional buildings and, in principle, just as efficient as buildings called ZERO or energy-neutral balance.

The PH reference is extraordinarily useful in this context, because it is a Standard that incorporates unfamiliar technologies or processes into current buildings. Consequently, it demands new energy and usage habits from the user. This produces a transforming effect on the habitual or conventional practices that we have internalized.

The Gram-Hanssen Scale has been used to establish four elements that, when fully developed, determine that a social or behavioural practice is assumed in society.

Spain and consequently the Balearic Islands adopt the PASSIVEHAUS Standard with the “Código Técnico de la Edificación” (CTE), the main set of regulations governing the construction of buildings in Spain since 2006. The basic quality requirements that buildings must meet relate to safety (structural safety, fire safety, safety in use) and habitability (health, noise protection and energy saving).

The objective of the basic requirement “Energy saving” consists of getting a rational use of the energy necessary for the use of buildings, reducing their consumption to sustainable limits and also getting part of this consumption comes from renewable energy sources, as a result of the characteristics of the project, construction, use and maintenance.

To meet this objective, buildings will be designed, constructed, used and maintained in such a way that the basic requirements are complied with.

One of the basic requirements is the limitation of the energy demand, for that requirement the buildings will have an enclosure with characteristics such that it limits adequately the energy demand necessary to reach the thermal well-being depending on the climate of the locality, the use of the building and the summer and winter regime, as well as their characteristics of insulation and inertia, air permeability and solar radiation exposure, reducing the risk of the appearance of superficial and interstitial condensation humidities that may damage their characteristics and adequately treating thermal bridges to limit heat losses or increases and avoid hygrothermal problems in them.

That is where DISPER together with GRIESSER and CORTIZO can and want to contribute in a small way. We offer products that meet the requirements of the CTE in terms of energy savings. Blinds that reduce the entrance of heat or cold in our houses, Bioclimatic pergolas that, with their adjustable slats adjust the amount of sun that we want to enter our homes, lattices, glazed ceilings, awnings, panoramic enclosures, Mallorcan blinds, and joinery that have the RPT thermal bridge break system.

If we are talking about thermal bridge break, we are talking about insulation. The evolution of building materials for housing improves the insulation capacity in our homes, but if we do not insulate our windows we will not get total insulation. A large part of our aluminium joinery systems incorporates the thermal bridge break system which consists of insulation incorporated into the frame, which improves the overall performance of the window. Over the years we have improved the insulation with double and triple glazing systems which is a great improvement, for that reason we could not forget the windows of our homes.

Thermal breakage in windows and doors adds additional benefits. The thermal cutting technology features a reinforced polyamide bar between the inner and outer aluminium profiles, creating an insulated barrier within the window frame. This will conduct heat, cold and noise a thousand times slower than standard aluminium. By installing double glazed windows and doors with thermal break, we can stop the noise by up to 80% and keep our home cooler during hot summers and warmer during winters.

  • Flame retardant in fires.
  • Increased security level.
  • Low maintenance.
  • Durable.
  • Non corrosive.
  • Thermal cutting technology.
  • Excellent thermal and acoustic insulation.

DISPER wants to demonstrate its commitment, to contribute as an active part and to stop, within the possible global warming.
In order to meet this objective, buildings will be designed, constructed, used and maintained in such a way that the basic requirements are met.
