Energy Efficiency and Sustainable Building Certificates

Sustainable construction certificates are tools created following the unquestionable interest in sustainable construction or green building, energy efficiency and passive houses.

The way they work is simple: under standards designed by each certifying body, different points and requirements are analysed and the building is awarded a score based on the results obtained. This rating is awarded by a specialised certifying technician.

Why is it important? Given the trend, interest and relevance that sustainable and ecological construction is taking, we can venture that demand will continue to grow to the detriment of traditional brick or cement. Having a certificate that qualifies our home or building with one of the certificates that we present to you will increase its value, and probably the other way round if it does not have one.

Is it very expensive? No, it is not very expensive. The cost of the certification itself will depend on the volume of the building or house, but don’t be scared, it is not expensive, it can cost from 5000 euros to approximately 10,000 euros. The key is planning, foreseeing from the design of the project. In any case, you should bear in mind that it is not possible to make a definite statement on the matter, as these costs depend directly on the type of project.

Is it compulsory? No, it is not, it is not even essential. In fact, all our constructions are already focused on obtaining the best energy efficiency and providing the best well-being for their inhabitants. Your decision must be based on the capacity to assume the increase in budget and the possible future revaluation.

Here are three of the best known and most in-demand certifications, Passivhaus, Breeam and Well.

Having a certificate is not compulsory, but it will facilitate later revaluation.


Of German origin. Emerged at the end of the 80s of the last century. It is the best known certificate.

Certification based on optimising thermal insulation, on obtaining high energy efficiency by presenting a very low consumption of heating and cooling.

For lovers of figures and technical data you can visit this Wikipedia link, where you will find detailed information as well as technical links.

– Thermal insulation
– Highly insulated windows and doors
– Eliminating thermal bridges
– Ventilation with heat recovery
– Air tightness


Focused on reducing the impact of the execution of the work and the subsequent life of the building. Seeking the greatest comfort and health for those who use or live in it.

It is subdivided into categories:

– Management
– Health and Wellbeing
– Energy
– Transportation
– Water
– Materials
– Waste
– Ecological land use
– Pollution and Innovation

Well certification

Well allows to identify, measure and monitor the characteristics of built spaces that impact on the health and well-being of occupants.

These are the concepts they value:

– Air. Improving the quality of the air breathed in the building.
– Water. Providing access to high quality water.
– Food. Availability of fruit and vegetables and nutritional transparency.
– Lighting. Natural and artificial lighting systems that improve comfort.
– Movement. Encouraging physical activity, active living and discouraging sedentary lifestyles.
– Thermal Comfort. Increased productivity through air conditioning design.
– Sound. Improving comfort by controlling acoustic parameters.
– Materials. Reducing exposure to pollutants in building materials.
– Mind. Supporting emotional and cognitive health.
– Community. Creating an inclusive, integrated and engaged community.
