On 17 June 2015, the Buildings Performance Institute Europe (BPIE) made available online 4 papers on Indoor Air Quality, Energy Performance Certificates, renovation strategies and fuel poverty. These were presented during the European Council for an Energy Efficient Economy (ECEEE) Summer Study conference held at the beginning of June.
On 4 June 2015, the Global Buildings Performance Network (GBPN) published a report entitled “Deep Building Renovation - International Policy Guidelines”. According to the report, savings in the existing building stock can only be achieved with the widespread adoption and implementation of effective policy packages.
On 2 December 2015, the Buildings Performance Institute Europe (BPIE) published a report entitled “Renovation in practice – Best practice examples of voluntary and mandatory initiatives across Europe”. This document analyses a variety of approaches and solutions available to tackle the renovation challenge in terms of scale, financing, addressing non-technical barriers, level of ambition or achievement of social objectives. in this regard, it includes 5 case studies which the authors believe could inspire and motivate policy-makers across Europe, and even globally. These include tackling fuel poverty, and streamlining public building renovation through Energy Performance Contracting.
In order to increase the amount of buildings which are renovated in a way which makes them more energy efficient, financing and investment needs to be made available. With this in mind, the “Investor Confidence Project Europe” (partially funded by Horizon 2020) aims to identify ways in which financing for the building renovation market can be unlocked.
On 25 March 2015, the Joint Research Centre of the European Commission published a report outlining the benefits which can be harnessed thanks to the energy renovation of existing buildings.

The Liberty Bridge is in Budapest, over the Danube River. This bridge was the 3rd which has made contact between Buda and Pest, at the end of 19th century. On the bridge there are railways, roadways and two sidewalks. In the middle of bridge lay the tram rails, and outside are the roadways.

This iconic post-war housing development needed to be brought into the 21st century.
The concrete structural grid was structurally sound and was repaired and retained to create modern living spaces.
With the aim of encouraging ‘national renovation strategies’, Green Building Councils from across Europe have joined forces and set up BUILDUPON, an EU project partially funded by Horizon 2020. Its mission is to support governments, industry and civil society in delivering ‘national renovation strategies’ over the next 12 months.
Renovation is one of the ways in which we can make buildings across Europe more energy efficient. However, there are still many challenges and hurdles which need to be overcome. For example, the building sector is relatively fragmented which makes it difficult to identify and offer holistic solutions for deep renovation at an acceptable cost and quality.
New research by the Massachusetts Institute of Technology may have found a way of identifying which buildings offer the greatest potential when it comes to retrofitting for energy efficiency. Thanks to these finding it may be possible to indentify which retrofitting programs offer the highest return on investment and have the greatest impact on a city's overall greenhouse gas emissions.
The need to address the existing building stock is mainly driven by energy efficiency considerations. Buildings alone are responsible in Europe for 40% of energy consumption, which makes it the single biggest potential sector for energy savings. For this reason, both the Energy Performance of Buildings and the Energy Efficiency Directives set targets to buildings to achieve the 20-20-20 strategy, and the latter even sets a minimum amount of total floor area to be renovated yearly by central governments.
