Maintenance represents the bulk of the costs occurring in a building’s life.

Less than three years ago, the so called “ Lavatrici ” district in Genoa (literally, “washing machines” in Italian) was in poor shape: infiltration, heat dispersion, energy waste.

Energy consumption in the construction sector is a key issue in the fight against climate change. It is often approached when planning new buildings, but there is little tendency to renovate the existing stock .

Just because your home was built in the 1950s or 60s doesn’t mean it can’t be green. Retrofitting – the process of modernising properties using the latest technologies – can save energy and reduce CO 2 emissions.

Smart buildings appear to respond to a range of energy challenges found in Europe today. Improved efficiency would help consumers reduce income spent on energy consumption, reduce greenhouse emissions and also help EU countries meet the goals of the 2030 energy strategy .

Buildings account for 36% of CO 2 emissions in Europe, and energy consumption in this sector has increased in recent decades.

Today, one of the new challenges for the construction industry is the use of textiles, coming from the clothing and footwear industries.

They live in a 1970s building complex bundling where they all have to share the energy costs of their significantly inefficient building. These running costs are unreasonable and have been known to reach five times the rent level.

Living or working in high energy-efficient buildings can be a great opportunity but users need to feel empowered. This means making them aware of the building features and allowing them to manage some of the appliances by themselves.

Bioenergy represents two-thirds of the energy produced from renewable sources in Europe, though biomass sustainability is not taken for granted.

San Pietro is a peripheral neighbourhood overlooking the city of Genoa, North-West of Italy. It is also known as Lavatrici (washing machines), because of the concrete slabs with empty circles that characterise the façades of its buildings.

Innovative technologies can be used to retrofit old buildings as a means to save energy. This is precisely what the Bricker project is aiming to achieve.

One of the  biggest challenges of retrofitting projects  is to make them attractive to residents. Now, one of them, the EU-funded project R2CITIES,  is analysing the initial first feedback received from residents  of the  Cuatro de Marzo  district.

To tackle climate change, new buildings are required to consume as little energy as possible . That’s because, in Europe, buildings are responsible for about 40% of our energy consumption.

Cuatro de Marzo is a district in the southern part of the Spanish city of Valladolid. It is a dense residential area with 190 privately-owned dwellings, developed in 1955.

Cities substantially contribute to European air pollution as they are the source of about 36% of the total CO 2 emissions. Modern cities therefore raise sustainability concerns.

Imagine a city could halve its energy consumption, costs and greenhouse gas emissions. This would get closer to levels that would ensure sustainability of resources.

Those who live in low-energy buildings are not experts. But energy professionals have been aware of the importance of meeting their needs, right from conception stage.

Restoring historic buildings and saving energy at the same time is now a reality. Passive house window expert Franz Freundorfer developed the heat-saver for the Waaghaus in Bolzano, a building from the 13th century .

A well-accepted measure for climate protection involves reducing greenhouse gas emissions . And buildings have the greatest energy saving potential, according to the official EU Energy Efficiency Plan 2011 .
