EU H2020 BuildHEAT - Standardized approaches and products for the systemic retrofit of residential Buildings, focusing on HEATing and cooling consumptions attenuation.
- Project duration: August 2015 - February 2022
- Project status: Approval by the Scientific Committee
- Funding: Societal Challenge (Horizon 2020 /EU funding /Project)
- Total project budget: €9,136,072.50

The total floor area of residential buildings in the EU-28 is approximately 18 billion m estimated to need heating to ensure comfort conditions. Heating needs are quite uniform all over Europe, amounting to around 140-170 kWh/m2y final energy consumption, compared to around 25 kWh/m
Cooling consumption is an issue only in the southern countries, where it generally ranges between 30 and 50 kWh/m 2y. In absolute terms, heating consumption in the residential sector in Europe arrives at around 2300 TWh/y, DHW consumptions reaches 500 TWh/y, while cooling consumption is less than 100 TWh/y (the total heat consumption in Europe is around 6500 - 7000 TWh/y). From this picture, it is clear that heating demand needs to be addressed most urgently. Nonetheless, a solution that covers both aspects and avoids a future increase of cooling loads in absolute terms is more attractive.
In line with the European Directives and Policies, the construction sector offers unique opportunities to decarbonise the European economy. However, as the replacement rate of the existing stock is very small (1-1.5 % per year), acceleration is needed. This has been true particularly in the past few years, when the turnover of the construction sector decreased significantly due to the economic crisis and has not yet recovered.
On top of this, the reorganisation of the sector poses tremendous challenges due to its extreme fragmentation: more than 50% of the residential buildings are owned by private single owners, 20-30% are rented by single tenants, while only around 10% are owned by social housing companies. Moreover, whilst few major industrial players are active on the market, it is largely dominated (more than 95%) by SMEs both on the manufacturers’ and the professionals’ side.
On the other hand, this sector offers a unique opportunity for sustainable business and social growth if: Efficient, systemic (tackling envelope and HVAC systems renovation) and easy-to-implement solutions are elaborated, allowing renovated buildings to approach the net-zero-energy standard and, at the same time, enhancing both comfort and healthiness conditions.
Efficient, reliable, non-intrusive and cost-effective technologies are readily made available on the market, facilitating the implementation of the systemic solutions Large investments are mobilized both from the public and private sectors, covering renovation costs that rarely can be borne by single private owners Information and coherence about available solutions is brought into the market, facilitating the decision making and planning processes.
