Today’s construction must not become tomorrow’s retrofit   

“Achieving a much deeper and increased building renovation rate is crucial to achieving the EU’s decarbonisation objective” says Mike Stenson of Kingspan in Foresight Climate & Energy, ahead of the second edition of European Energy Efficiency Day.

The way we build is evolving dramatically, with new materials, systems and technologies making it possible to create architecture that is more energy efficient, resilient and sensitive to the needs of its inhabitants than ever before.

To meet the Intergovernmental Panel on Climate Change pathway to limit the global rise in temperature to 1.5°C, it is essential for all sectors to decarbonise rapidly over the next ten years.

Buildings are currently responsible for 39% of global energy-related carbon emissions: 28% from operational emissions, from energy needed to heat, cool and power them, and the remaining 11% from materials and construction.

Back to school with our attention on energy efficiency

“As we approach the autumn season, Europe stands on the brink of a decisive momentvwith the negotiations on the Energy Performance of Buildings Directive gaining speed. Amidst this backdrop, Europe’s commitment to putting energy efficiency first is paramount,” says Luigi Petito of the European Alliance to Save Energy (EU-ASE) in Foresight Climate & Energy, ahead of the second edition of European Energy Efficiency Day.

The gains made by efficiency investment outweight the upfront cost​​.

In 2019, the European Union​​ set its sights on achieving climate neutrality by 2050. This​ was put into action through ​the European Climate Law. This not only enshrined the objective within the EU’s legal framework but also charted a course for an interim target—a reduction of greenhouse gas emissions by no less than 55%​ by 2030​ compared to the 1990 baseline, on the trajectory toward 2050.

​​The seismic geopolitical events of 2022, marked by Russia’s invasion of Ukraine, have acted as a catalyst for Europe’s energy agenda. More than five hundred days since the beginning of the war, a consensus has emerged—an imperative to accelerate Europe’s transition towards decarboni​s​​ation, thereby diminishing ​Europe’s​​ reliance on fossil fuels. ​​​ 

Within this context, a response to the energy crisis materiali​s​​ed through the REPowerEU ​package​, outlining the strategic goal of liberating the EU from its dependence on Russian fossil fuels well before 2030.

Unlocking the Superpower of Buildings

“The relatively simple act of renovating residential homes with proper insulation would result in a 44% reduction in the amount of natural gas used for heating. Th​is is​ not only a substantial decrease in energy consumption, it​ i​s also a big decrease in associated carbon emissions — This is​ the superpower of buildings” says David Ducarme of Knauf Insulation in Foresight Climate & Energy, ahead of the second edition of European Energy Efficiency Day.

Europe’s built environment is the single largest consumer of energy. It is also one of the largest emitters of carbon dioxide (CO2)​. But while the building stock’s carbon footprint may be big, it also has a superpower that can be unlocked using energy-efficient renovations.

For energy efficiency to be more than an after thought, it needs to be viewed as another element in the power mix. According to calculations by the Buildings Performance Institute of Europe (BPIE), the relatively simple act of renovating residential homes with proper insulation would result in a 44% reduction in the amount of natural gas used for heating.

This is not only a substantial decrease in energy consumption, it is also a big decrease in associated carbon emissions—a decrease that would help put Europe on track to becoming the world’s first climate-neutral continent.  

This is the superpower of buildings. 

But unlocking this power requires policies that deliver energy efficiency, which is why the revision of the Energy Performance of Buildings Directive (EPBD) could not be timelier

Interview: To shave peak demand, EU states should impose ‘flexibility’ on industry

“The EU’s high gas dependency can be reduced through both electriciation and energy efficiency,” Francesco Venturini of Enel X Global Retail told Frédéric Simon of Euractiv ahead of European Energy Efficiency Day 2022.

The biggest potential for short-term energy demand reduction lies with industrial consumers, says Francesco Venturini. Those savings can be tapped with programmes that reward businesses who adapt their demand to energy supply, he argues.

Interview highlights:

  • Big industrial loads offer the biggest opportunity to efficiently manage peak electricity consumption
  • EU countries should introduce forms of mandatory flexibility, rewarding businesses that are able to adapt their demand to electricity supply
  • Europe has sufficient gas storage to get through this winter without rationing. Potential shortages could especially affect the winter 2023-2024 and the following ones
  • Today’s high gas prices are driven mostly by speculation. This should be reined in with the introduction of a temporary price cap on European gas
  • For private consumers, regulations should be adjusted to encourage energy self-consumption, like solar panels and batteries. Other examples include citizen-led Energy Communities, tax deductions for heat pumps, removing subsidies for gas boilers, and a ‘right to plug-in’ for consumers
  • When it comes to public spending, Enel believes policies that promote energy savings from direct fossil fuel combustion must be excluded from eligible measures to achieve EU members states’ energy savings obligations

Insulation exec.: ‘Heat pumps alone will not do the trick’

Energy efficiency has a huge role to play to deliver renewable energy to households whilst limiting costly investments into energy capacity for society, David Ducarme, Group chief operating officer at Knauf Insulation told Frédéric Simon of Euractiv.

A properly insulated home will allow heat pumps to deliver their “magic trick” – a 400% efficiency rating over the 90% figure observed for fossil gas boilers. Yet, these efficiency gains will not materialise unless homes are heat-pump ready, says David Ducarme.

Interview highlights:

  • Long-term measures to reduce energy demand are essential to address the root causes of the energy crisis Europe is facing.
  • Buildings remain Europe’s year-round weak spot in the energy transition. Drastically improving the energy performance of buildings envelopes would decrease by 45% the energy demand for heating and cooling from buildings.
  • Heat pumps alone will not do the trick. A properly insulated home will allow heat pumps to deliver their “magic trick” – pulling four units of heat out of each kilowatt-hour (kWh) of electricity. Otherwise, they will not deliver as much.
  • Heat pumps will also pose challenges to the electricity grid, with demand for electric heating set to increase by 356 Terawatt hours per year (TWh/y). Without insulation, the additional generation capacity needed to meet peak winter demand would need to be 2,129 TWh/year, almost five times more.
  • The revised Energy Performance of Buildings Directive (EPBD) and Energy Efficiency Directive (EED) will be the backbone of resilient and decarbonised building stock.
  • Long-term decarbonisation of the building stock also entails setting long-term trajectories on whole-life carbon reduction.
