EDEA Project Presentation

Objetivos Proyecto EDEAThe deterioration of the environment, and particularly the climate change, forces society as a whole, -and all the productive and economic sectors which cause it- , to a deep reorientation in production and consumption patterns.

In the European Union, building construction consumes 40% of materials, generates 40% of waste products and consumes 40% of the primary energy. These statistics tell us about a sector having a deep impact on economy, ecology and social media, ultimately an unsustainable sector.

The importance of construction sector gives us an idea of the need of changing the way to design, build, maintain, renovate and demolish buildings and their enviroment, wich will allow to establish the improvement of enviromental, economical and social “benefits” in towns and cities and in the citizen´s quality of life. Ultimately, should aim towards a model of sustainable construction.

Therefore, the Ministry of Public Works of the Regional Government has the need to develop a design and building methodology for social housing in Extremadura, in order to obtain houses under sustainability criteria, with a better energy performance and using new renewable energy resources, in addition to ensure the improvement of building quality.

The materialization of this idea will be possible through the construction of two single-family isolated dwelling units, according to the Special Housing Plan typology.

The Special Housing Plan developed by the Regional Government of Extremadura aims to build houses throughout the whole region, affordable to social groups of limited income. This Plan will be developed by means of the construction of different typologies of housing.

These two single-family isolated dwelling units will have the same orientation and structural system, therefore they will be under the same weather conditions. The first of these will be built according to the same construction detailing as those of 80 square meters which are currently being built in Extremadura for the Special Housing Plan. That house will be the “dwelling unit pattern". Different sustainability and renewable energy measures will be tested in the second house, it will be named the “experimental dwelling unit”. Both houses will ensure to observe the Spanish Building Regualtions (CTE) strictly.

The relationship between the “experimental dwelling unit” behaviour and the “dwelling unit pattern" one, will allow us to obtain comparative real-time data from passive/active systems tested in our demonstration projects. In addition, through a rigorous methodology, will allow us to know how will behave each one  of the variables that are altered and the consequences on the “experimental dwelling unit” energy demand.

The project features which support its singularity and novelty are: 

  • It is tailor-made to particular weather conditions, the ones of the Extremadura region. 
  • It is focused on a specific housing tipology and specific low income population
  • There will be obtained reliable data about the efficiency of the testing methods applied on the “experimental dwelling unit” in comparison with the “dwelling unit pattern", whose constructive systems are typicaly used in Extremadura social housing.
