Some 15.4 % of the EU population reported that they live in dwellings with a leaking roof, damp walls, floors or foundations, rot in the window frames or the floor. And some 8.7 % are unable to keep their home warm enough.

Local governments in Europe are notoriously risk averse, city council officials and industry leaders won’t hesitate to tell you.

Home sweet home. Houses are supposed to be our nest, a shelter from the world outside. But how healthy are European homes? Nowadays most of our time is spent indoors, often at home, one reason being the current shift to “desk jobs”.

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.

There is growing interest in crowdfunding as an alternative way to support projects focused on renewables. This comes at a time when the green energy sector is feeling the purse strings tighten in many European countries.

In 1961, the physicist Rolf Landauer formulated a principle that any transformation of information that takes place in a computer requires energy, thus making zero-power computing a pipe dream.

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 .

Thousands of kilometres of increasingly sophisticated and cutting-edge transmission lines, in other words supergrids , are on the EU agenda. Projects for high voltage links between countries are already being implemented.

Despite increasing talk about renewable energy, many people remain far removed from what’s going on. To tackle this, various projects have been developed over the years helping users to better understand and use green energy sources.

Islamic finance abides by the Sharia law. It demands socially responsible investment, with a real impact on the community.

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.

Today the challenge is to enable better transmission from one country to another while reducing CO 2 with efficient links between renewable energy and the grid.

Italy is famous all over the world for its historical cities, but their beauty is not enough anymore. They want to be smart. Two of the experimental forerunners developing energy efficiency measures are Udine and Salerno .

The energy landscape in Europe is changing rapidly and the percentage of renewables is steadily increasing. For example, in Germany solar and wind power provided an average of 33% of the total electricity production in 2015.

As more and more cities launch projects to become smart, a substantial need is emerging: the ability to share the various models across the world so that they can be replicated anywhere.

There are three ways a crowdfunding project can be financed. Lending: the entrepreneurs borrow money and pay interest; equity: investors in the project become its shareholders; donations: no reward is to be expected (there is a fourth way, a mix of equity and lending called “hybrid”).
