Building and Renovating in an Energy and Resource Efficient Way

Building and Renovating in an Energy and Resource Efficient Way

anthony-delanoix-b5POxb2aL9o-unsplash

Achieving climate neutrality by 2050 requires a boost in the rate and depth of building renovation in Europe.

Copper’s inherent properties make it a material of choice for decarbonized and sustainable buildings, and the copper industry strongly supports the European Green Deal’s ambition to build and renovate in an energy- and resource-efficient way.

    The Renovation Wave

    Buildings account for approximately 40 percent of energy consumption and 36 percent of CO₂ emissions in the EU. More than 220 million building units, representing 85 percent of the EU building stock, were built before 2001. Projections indicate that 85 – 95 percent of today’s buildings will still be standing in 2050, highlighting the need for an increase in the rate and depth of building renovation to reach climate neutrality by 2050.

    The European Commission’s Renovation Wave Strategy is at the heart of Europe’s post-Covid recovery and aims to green our buildings, create jobs and improve lives. The key targets are:

    • By 2030, the EU wants to reduce greenhouse gas emissions from buildings by 60 percent, final energy consumption by 14 percent and energy consumption for heating and cooling by 18 percent.
    • The Renovation Wave addresses the low rate of energy renovation—about one percent across the EU—with the aim to double the rate for both residential and nonresidential buildings by 2030.
    • Mobilising forces at all levels will result in the renovation of 35 million units by 2030 and up to 160,000 additional green jobs created in the construction sector.

    Copper Drives Deep Energy Renovation
    coppers-role-in-climate-neutral-renovation (1)

    Many building applications and renovations require copper.

    • Copper is a key material for safe electrical installations (wires and cables), electric vehicle (EV) charging infrastructure, renewable energy generation (photovoltaics) and storage (batteries).
    • Copper improves the efficiency of heat exchangers in heat pumps, solar thermal systems and waste heat recovery systems.
    • Copper wiring is fire resistant, and with proper sizing, it can improve efficiency.
    • Copper is used in sensors, actuators and cables in building automation systems.

    The Importance of Safe and Future Ready Electrical Installations
    Electrical%20installations%20infographic%20GIF.gif

    The role of electrical installations will become increasingly important in buildings because of:

    • The electrification of heating and cooling
    • The development of e-mobility charging infrastructure into buildings
    • The development of on-site renewable power generation and storage
    • The integration of buildings into smart grids

    View our infographic: Electrical Installations are the Backbone of Decarbonised Buildings

    High quality electrical installations in buildings must be considered as a prerequisite for the green energy transition based on following key considerations:

    Electrical safety: Half of accidental residential fires have an electrical origin. They are all highly preventable via regular inspection of electrical installations. More details

    Future-readiness: Electrical installations must account for the energy transition that will rely on increased electrification. Electrical installations need to be part of renovation plans and anticipate future needs, such as the installation of heat pumps, smart EV charging, PV panels or batteries. Information should be provided to occupants about the future readiness of the installation.

    Economic cable sizing: In buildings, 64 TWh energy (two percent of electricity generated in the EU) is lost in behind-the-meter networks. Electrical installations should be considered as technical building systems (TBS) and designed for energy efficiency.

    Smart sector integration: Highly efficient heat pumps, EV charging infrastructure, and renewable energy generation and storage needs to be smartly integrated into buildings and the grid to minimise congestion, consequent future upgrade investments and delays of the energy transition. Building Automation and Control Systems (BACS) are the missing link between carbon-neutral buildings and a smart and secure energy system. (More info: Building Automation: the missing link between carbon-neutral buildings and a smart and secure energy system)

    Cable Sizing for Fire Conditions: Cables providing electrical power to live-saving equipment must guarantee they function under extreme temperatures to allow building occupants time to escape. Cable sizing for fire conditions is different from normal operating conditions because electrical resistance increases sharply as temperature rises. A correction factor must be introduced. (More info: Fire resistant cables on safety equipment)

    Copper and Sustainable Buildings

    Construction must become a circular activity. Sustainable renovation supports this process by reducing impacts over a building’s life cycle. Copper is a material of choice for sustainable buildings.

    • Copper products can be recycled infinitely at end of life (EoL) and are already highly recycled. Approximately 50 percent of the copper used in Europe comes from recycling, and the scrap value chain is well established.
    • Copper products are durable, reliable and repairable.
    • The copper industry has an established a credible assurance framework, the Copper Mark to promote responsible production practices and demonstrate the copper industry’s commitment to the green transition.
    • Copper has long-term availability.
    Our Activities

    The European Copper Institute (ECI) supports the renovation wave and is a partner of the Coalition for Energy Savings and of the Renovate Europe Campaign.
