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.

Investing in energy efficiency: if not now when?

As the cheapest & cleanest energy is the one we don’t need, rapidly increasing energy savings is of outmost importance to address the current crises, says Monica Frassoni in Euractiv, ahead of the first edition of the European Energy Efficiency Day conference.

More than two hundred days have passed since Russia launched a full-scale invasion of Ukraine, starting a tragic conflict in Europe with no clear end in sight. The use of energy as a weapon by Vladimir Putin shows that by delaying plans for a clean energy transition the EU is more vulnerable and insecure.

While emergency plans are underway to respond to the crisis, skyrocketing prices of wholesale fossil gas and electricity pose a real challenge to struggling citizens and businesses and put at great risk the post-pandemic recovery.

Today, the pressing question everyone is asking is: how can we make it through the next winter and how can we reduce quickly energy prices? But the real question should be: how can we make it through the next four-five winters and burning summers, and at the same time accelerate carbon emissions reduction.

Because the cheapest and cleanest energy is the one we do not need, rapidly increasing energy savings is of outmost importance. By mainly focusing on diversification of gas supply many governments are underestimating the massive savings potential that is currently untapped at end-use and system levels via retrofitting, demand-side flexibility and by accelerating the digital transition.

Energy Efficiency and renewables are two sides of the same lucky coin

Energy efficiency measures, coupled with renewables, are the right tools for achieving carbon neutrality and protecting our energy sovereignty, says Francesco Venturini of Enel X Global Retail ahead of the first edition of the European Energy Efficiency Day.

 

Citizens, businesses and local governments must join forces to equip themselves with facilities for the production and self-consumption of energy from renewable sources by promoting virtuous behaviours.

Today, market transformation is happening in a very disruptive way. The historical events of the past six months demand an impressive acceleration of the trajectory outlined by the European Green Deal in 2019. Looking back at the past eight years, global investments in clean energies have blossomed to $371 billion, an increase of approximately $60 billion compared to 2014 levels.

Is there enough to go around? The answer for most of us is simple: no.

The Ukraine conflict and its consequent war on prices are proving that our society does not have access to abundant, reliable, cheap and clean energy—placing its economic and social progress at stake. 

But we still have a lucky coin in our pocket: energy efficiency measures can substantially reduce Europe’s carbon footprint if combined with consistent investments in renewable energy.

A battle for the climate inside buildings

Amidst the climate and energy crisis, Europe’s ageing building stock provides a challenge—and an opportunity, says Julie Kjestrup of the VELUX Group ahead of the first edition of the European Energy Efficiency Day.

There are more benefits to energy efficiency measures than simply saving money. Climate change is happening rapidly and so are the consequences of not fighting it adequately, intentionally and consistently. Despite scientists showing us the marked impact of climate change as well as what we need to do to mitigate it, we are not currently on the right path towards meeting the Paris Agreement and the EU’s 2050 climate neutrality goal. Add to that the recent hike in energy prices and fast action is essential. We can still get on track if we all play our part by taking responsibility and acting now.

Decarbonisation through digitalisation: The key role of smart city districts in boosting energy efficiency

Smart buildings are energy-saving, sustainable buildings. Clustered into smart city districts, they play a crucial role in climate protection. The adaptive, open-source technology to make this possible is already available, says Matthias Rebellius of Siemens Smart Infrastructure on Foresight Climate & Energy ahead of the first edition of the European Energy Efficiency Day. 

Decarbonisation comes with a simple truth: kilowatt-hours that are not consumed do not have to be produced. They do not have to be stored or distributed. And when we are saving energy to avoid carbon emissions, this becomes all the more critical.

Efficiency is key, especially in the building sector. Buildings account for 40% of global energy consumption. But the average building still wastes up to 50% of the energy it consumes. Equipping or retrofitting a building with digitalised, networked and intelligent systems can reduce its ecological footprint by up to 80%.

Efficiency is more than modern insulation and state-of-the-art heating systems. We need smart building technologies and efficient building operations if we are going to move the needle on decarbonisation, especially in brownfield applications. A huge amount of leverage is being wasted. Buildings should—and can—contribute much more to the global decarbonisation effort.

Yet we must not focus just on buildings. We have to take into account synergies and efficiency gains on the community and city levels.
