This is the first block of housing certified in Spain built in 2017 under the Passivhaus standard, and therefore has a demand for heating below 15kWh / m2a, and a heating load of 10W / m2.
This implies that a floor of 75m2 will have a heating load of only 750W, so with a hair dryer there would be enough to heat two houses.
To achieve this the following principles have been applied:

Historic buildings are defining elements of city centres but also responsible for a large share of greenhouse gas emissions. In order to reduce their energy demand, it is important to improve envelopes’ thermal transmittance without damaging the historic integrity of their façades by applying interior insulation.
Thus, a detailed planning is needed to guarantee that case-specific variables are well considered. In this study, a holistic performance-based evaluation method is developed.

The seismic and energy retrofitting of existing European buildings with innovative materials is addressed in this report. The need for retrofitting of old buildings emanates from their substandard design in terms of both earthquake resistance and thermal insulation. This is revealed during strong earthquakes that result in collapses and damages of old buildings and consequently in economic losses, severe injuries and loss of human lives.

"Die energetische Gebäudesanierung gehört zu den zentralen Stellschrauben der Energiewende. Der Gebäudebereich allein ist in Deutschland verantwortlich für rund 35 Prozent des Energieverbrauchs und für 30 Prozent der energiebedingten CO2-Emissionen. Ein besonderer Fokus der energetischen Sanierung liegt dabei auf privaten Wohnhäusern, die knapp zwei Drittel des Gebäudebestandes ausmachen. Es gibt in Deutschland rund 14 Millionen Ein- und Zweifamilienhäuser und etwa vier Millionen Mehrfamilienhäuser.
