With its new factsheets, the Horizon 2020 project RenOnBill provides key insights on the residential building sector of its four focus countries: Germany, Italy, Lithuania and Spain.
Each factsheet, available also in the respective national languages, gives key insights on the role of the construction sector in each country, on the size of the building stock, on the country energy efficiency targets and the main trends in the renovation market.
The factsheets also contain specific sections on the regulatory framework in place and on the available financing mechanisms to support renovation.
For example, residential buildings represent almost 90% of the total Italian building stock, compared to the 60% of the Spanish one.
Germany’s overall long-term political goals include a 55% reduction of greenhouse gas emissions by 2030 and a reduction of 80% by 2050. Italy’s ones instead include a 43% cuts in greenhouse gas emissions and a 43% improvement in energy efficiency by 2030.
As for the Lithuanian situation, multi-apartment buildings built before 1992 hold the greatest potential for reducing energy consumption and increasing energy efficiency to reach European targets.
But even though these apartment buildings – currently rated energy class E or F – can reach a C class after renovation and reduce heating consumption by 40 to 60%, there are several barriers to achieving their renovation on a wide scale.
Also in Spain, the greatest potential lies in the buildings built prior to 1980, representing more than half of the total building stock.
