New guidance from the U.S. federal government, combined with historic Inflation Reduction Act investments, could turbocharge markets for low-carbon cement, steel, and other building materials. Victor Olgyay, Anish Tilak and Connor Usry at Rocky Mountain Institute explain how the new âBuy Cleanâ recommendations will mean the procurement of green building materials for federal building and transportation projects. That will lead to a boost in … [Read more...]
Buildings Renovation: city-wide comprehensive data management tools to transform each building
In the U.S. the National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory have created a free-to-use and (and develop) online data management tool â called SEED - that allows whole cities to collect details on thousands of buildings and use them to assess energy wastage at the single building level. Molly Rettig at NREL explains that hundreds of data points can be collected for each building. The tools, along with … [Read more...]
EU Heat Pumps: warnings against âone size fits allâ policies
The EU is aiming for the installation of 50 million heat pumps by 2030, equating to annual growth of 16%, reaching one third of the total 150 million boiler installations in the bloc. Helen Farrell reviews these ambitious targets and the policies that are driving them, and turns to a report by RAP to identify the weaknesses in the plan and how it can be improved. The main danger is a âone size fits allâ approach. Different countries have … [Read more...]
46% of Buildings âEmbodied Carbonâ can be slashed at little to no cost
Buildings and their construction account for around 40% of all carbon emissions today. Half those emissions come from the construction alone, so buildings successfully powered by clean energy wonât come close to fixing the whole problem. John Matson and Rebecca Esau at RMI describe how industry leaders are creating the tools to measure and gather data on the âembodied carbonâ in building materials (concrete, rebar, glazing, insulation, other … [Read more...]
Buildings Renovation: if Europe had started a decade ago it wouldnât have a Russian oil & gas problem
Itâs a message we are starting to see a lot. If ambitious climate policies struggling to be implemented today had been launched a decade ago, Europe wouldnât have a Russian oil and gas problem. Andreas RĂźdinger at IDDRI looks at buildings renovations in France. Two missed targets, proposed in 2008, are a 38% reduction in energy consumption in existing buildings by 2020, and 400,000 âmajorâ renovations annually. If they had been met, natural gas … [Read more...]
Why sustainable Buildings are critical for a resilient, healthier society
Europe and its Member States are committing large sums to buildings renovations. The policy emphasis has been on insulation, energy savings and emissions reduction. The latest Healthy Homes Barometer 2022 by Velux draws attention to the health benefits of renovations that target damp, lack of daylight, excess noise or cold, and other indoor climate hazards. To get an idea of the scale of the problem, 34 million Europeans are unable to keep their … [Read more...]
Factory-built energy-efficient modular affordable Housing for reducing lifecycle emissions
Building construction and operation accounts for 37% of global energy-related carbon emissions, according to the UNEP. And every part of the world needs new housing. The U.S. has a 3.8-million-unit housing shortage. Jeffrey Wolf, writing for NREL, describes how modular factory-made affordable net-zero housing is being developed that costs no more than existing construction methods. To get the greatest decarbonisation impact most cost-effectively, … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
If Buildings Renovation fails, the EU ETS pricing mechanism must change
If the EU âRenovation Waveâ for buildings fails, the massive ramp up of clean electrification required to compensate will come into direct conflict with EU ETS pricing formulas, say Sebastian Osorio and Michael Pahle at the Potsdam Institute for Climate Impact Research and Oliver Ruhnau at the Hertie School in Berlin. If the cap in the original ETS is too tight relative to the Effort Sharing Regulation (ESR) targets, its carbon prices may rise … [Read more...]
District Heating Roundtable: Policy across RED, EED and EPBD “must take account of conditions in all Member States”
Sara Stefanini provides a written summary of our panel discussion held on 10th February: District Heating under the "Fit for 55" package: challenges and opportunities. Under the âFit for 55â package, the EC proposed several regulatory changes that, combined, are meant to decarbonise district heating in Europe. But are these options workable for all? The participants raise questions over the support for district heating, whether the multiple … [Read more...]
EPBD Recast: New provisions need sharpening to hit climate targets, says BPIE
This policy briefing takes a critical look at the European Commission's December 15th proposal for a revised European Performance of Buildings Directive (EPBD). While many new tools are introduced, the recast proposal does not yet reflect the crucial role the EPBD should play within the Fit for 55 package. In December 2021, the European Commission published its proposal for revising the Energy Performance of Buildings Directive (EPBD). This … [Read more...]
District Heating: policies for cutting emissions need work says IEA
District Heating policies need urgent attention according to the IEA so here in Europe it's a good moment to examine what the "Fit for 55" package means for the sector's future development. On February 10 Energy Post is hosting an online roundtable alongside MEP Pernille Weiss, MEP Morten Petersen, and MEP Grzegorz Tobiszowski - all (senior) members of the ITRE committee - to take in the viewpoints of key Member States and stakeholders (COGEN … [Read more...]
Buildings: France and Flanders lead on decarbonising new builds
Buildings are responsible for 36% of total EU carbon emissions. So, since the start of 2021 European legislation requires all new buildings to be ânearly zero energyâ. The frontrunners are France and Flanders in Belgium, according to a new report from the Buildings Performance Institute Europe (BPIE), writes Clare Taylor. Both jurisdictions have plans for phasing out fossil fuels in new buildings within five years. Taylor explains how Flanders … [Read more...]
Intelligent, flexible Sector Coupling in cities can double the potential for Wind and Solar
This week the European Commission tabled the Energy Performance of Buildings Directive (EPBD) which should accelerate the decarbonisation of buildings. Buildings and cities play a key role in the energy transition. And the target high shares of variable renewable power supply will be much more easily achieved if the sectors using them display demand flexibility. In essence, that means using or storing the excess wind and solar generation … [Read more...]
Grid-Interactive Efficient Buildings: how to start saving from day one
Edie Taylor, Rebecca Esau and John Matson at Rocky Mountain Institute explain how their report âGrid-Interactive Efficient Buildings Made Easyâ identifies simple, low-cost steps that produce immediate cost, energy, and carbon savings. As utilities evolve their pricing structures to encourage users to avoid peak times, building managers must ready themselves with the controls that will allow them to buy electricity when it is cheapest. Demand … [Read more...]
