Energy and buildings: potential for change policies in support of energy efficient buildings

Buildings contribute to around 36 percent of the EU’s CO2 emissions, consuming 40 percent of total primary energy consumption. Improving energy performance of buildings is key to contributing to the EU climate & energy objectives, namely a 20 percent reduction in greenhouse gas emissions by 2020, a 20 percent increase in energy savings by 2020, and using 20 percent renewable by 2020. The opening plenary  examined the political framework for these elements in buildings from a local and sub-national perspective – with speakers reviewing the current situation, identifying options and solutions, and framework conditions needed to accelerate the process, both for new buildings and existing European building stock.

Welcome by host city and Local Renewables partner -  Dr. Dieter Wörner, Head, Environment Department, City of Freiburg, Germany

Technical solutions, clever design – energy efficient solutions for new and existing buildings

Existing standards and regulations and the latest state-of-the-art of technology in the building sector were placed under the microscope in this plenary. Bringing together experts from different fields -  such as science, planning and business - speakers and participants explored key technical developments, standards and solutions for clever building design. Questions were posed, such as, which of these cutting edge technologies can most easily be rolled- out and why are passive house and similar efficiency standards not yet widely applied. How can we engage the interest of local decision-makers in choosing the optimal energy efficiency solutions?

B1 – Driving energy efficiency innovation at all stages of the public construction process

Every public construction project - whether a renovation project or a new building - involves a multitude of different public and private actors, with various and complex procurement procedures. The leap from wanting to reach a sustainable outcome to achieving one is equally complex. The SCI-Network has been exploring different methods for encouraging innovative, sustainable outcomes within the typical procurement process for construction projects. This session explored some recommendations. Issues included, how to engage with the private sector before tendering for construction services, how to set up procedures to maximise expert involvement, and how to assess the life-cycle costs of construction in the decision-making process.

A2 – Renovating historical buildings: where to invest?

Historical buildings can consume a significant amount of energy and in many cases are particularly difficult to improve energy efficiency, due to restrictions applying to monuments and the sensitive building structure. European historic building centers are the hallmark of the continent, drawing many tourists, yet also have enormous retrofit needs. In this session, experts from various European retrofitting projects discussed the challenge of retrofitting historical buildings and how to do so efficiently while  complying (or creating new) with rules and regulations for the conservation of ancient structures.

B2 – District heating and cooling: technical solutions


District heating and cooling running on renewable energy using efficient systems can play a significant role in the supply of low-carbon energy in Europe. Optimising systems by using waste heat and heat recovery, linking to geothermal energy or hydro-power – there are many different solutions to make heating / cooling more efficient. This session addressed how to make sustainable energy district systems more interesting for roll-out and policies needed to support this and replace non-optimised individual heating concepts.
