Those of us who have been in the process for a long time energy certification in Spain we remember a significant date, the 1st of June 2013. By April of that year, a Royal expectation was approved Decree 235/2013 of April 5 in the BOE that promulgated the obligation to carry out the certificate energy as an unavoidable issue. what times those!... Where the illusion of new perspectives of stable job was the talk of everyone professionals in the architecture sector.
From Brussels, years ago, they already warned with their energy efficiency directives, especially the Directive 2010/31/UE, that the buildings were and are the largest energy consumers in the world, and which represent more than a third of the final energy consumed on the planet (The places where we live and work are responsible for up to 40% of the final energy consumption and 36% of the carbon dioxide emissions across Europe). in equal extent, are one of the largest sources of carbon dioxide emissions carbon. Reduce consumption energy and emissions in the sector real estate must be a public cause with objectives achievable, according to Brussels, and one of the most effective in the short term is the use of the process certification.

This is where the certificate of efficiency came in force energy of buildings for that 2013 with the aim of identify “diseases” at the level of efficiency energy of homes, buildings, premises... etc. Through a conscientious diagnosis, also adding a set of suggestions that allow homeowners of buildings to adjust and correct the identified problems. With certification obligations for:

When a project or purpose aimed at citizens does not it has a good coherent base and mainly, it is not explains well… What is the certificate for? Which are advantages and benefits? What does it contribute to consumer? Do we get a reaction like those expressed in the recent article in the newspaper El País with the title "Reluctant to certification energy» and the tagline that precedes « Most homeowners advertise their homes without mandatory labeling.
We must remember which buildings are required to perform the certification process, from the responsibility of the promoter, even the owners:
After three years of certification, an almagraba from legislation by communities that in some cases are very correct and in others they correspond to an absolute ambiguity protected by a state regulation that continues, to this day, falling back into legislative confusion. It remind us, that the feeling that the citizen of the document is one more tax…. three years we have had to repair and clarify concepts, and the result is the same than June 1, 2013. We can see the article from September 2013 (El País) with the headline
Covering a little more, that is, entering the IEE Building Assessment Reports it seems that we are going along the same path as energy certification, both in the absurd price war as in the little information before the citizen, and if we enter the sector of the energy audit, we are falling back on the same guidelines with the news from the newspaper El Economista Here with the overwhelming title of "The price of the audit energy falls by 80% and fraud is expected”.
Although the Ministry of Industry offers us a June 2015 report with the data and status of the process of certification by Autonomous Communities (Here) we must broaden the vision and comparison with other countries, so we can determine if we are in the right direction or not. Here comes into play on the Zebra2020 portal and we remember the article certification trends energy.
Zebra2020 focuses on monitoring the market and advances on consumer buildings of almost zero energy (Net Zero Energy Building or nZEB) to derive recommendations and strategies for the sector of construction and policy makers, with the intention to accelerate the absorption of the real estate market of the nZEBs buildings where the behavior of the certification process of the different EU countries.
By means of an interactive tool with maps we can Compare different countries or as a whole. If we go to the energy certification for new buildings, case residential, we will have the following graph:
I think there is no need to guess which country is in more red. OJo!… these are data for new buildings with a high index on labels with an "E" rating for Spain. That is, with better and less acute climatic conditions than the most EU countries, we continue to build buildings less efficient.
We remember, and we will not tire of repeating, that from HERE we have a Time Line, a follow-up constant of major changes in the process of certification since 2015.
This is one of the most controversial aspects, mainly because there has been no information that clarifies concepts and information, and this is essential to know what we do in the certification process, not only consists of managing the Ce3X, Cerma or CE3.
There is a new document that presents information that practically every certifying technician should have , to our knowledge. It is the Manual of user of the CTE analysis ISOVER Complement for Ce3X (HERE) covering two points; one is the use of ISOVER plugin, which at the end of the article we explain why we should use it, and various schemes – final part of the document – which clarify very well the calculations, processes and justification of the Technical Code . An example is:
Scheme of new building or expansion of the existing building
Existing building scheme
This aspect should be over, but we continue finding reports literally with just sheets, not one more, and in reality that represents a decline in the technician professionalism. They offer the right information and that it is useful to the client is one of the aspects that we must take care of, remember that our client is our best advertising Apart from the presentation of report, I mean the visual aspect, we have to consider other aspects:
There is a lack of consistent observations in the reports, and notice that At the time we put a lot of emphasis on this issue, both for protect our backs from possible legal actions such as justify different points of the report. The article that what we do is what observations to add in the certificate energetic. It is evident that each one must adapt them to your report and your way of writing, but we provide some basic guidelines.
A guide to energy efficiency with basic concepts. No it is only to "release the report", it is to inform our client of the basics of energy saving. from the article 100 Energy Efficiency Guides you can get a lot information and write your own report, such as the that we use:
Currently we have different tools to complement the improvement measures required in the certificate energetic. In our opinion, the best would be the Plugin ISOVER for the Ce3X, the so-called iConecta. Two reasons main, first because it is covered by a serious company and who cares about the constant updates of the complement to the changes that occur in the Ce3X and in Secondly, because it is designed with an eye to the future. Is say:
To further clarify concepts and the objective of the plugin for Ce3X highly recommended to see the following explanatory video that was made in Foro Hábitat
We can also read more about how to use it from a article of this portal Here.
Other qualities is that it has a quality manual technical and well explained, which we have commented previously and we repeat… HERE. So, provide measures of real improvement in reports is no longer a problem for technicians.
