Energy poverty – the inability to afford basic household energy needs – affects up to one-third of U.S and European households. The energy transition can be part of the solution, says Clare Taylor. Targeted energy-efficient retrofits and newbuilds for low-income households will cut bills and improve living conditions. This will not only cut emissions, but get the beneficiaries behind wider climate change policies like the Green Deals in Europe … [Read more...]
Central and Eastern Europe’s buildings renovation plans fall far short of 55% emissions cuts
There are big decarbonisation gains to be had in a renovation wave in Central and Eastern Europe (CEE) precisely because their building stock is very energy-inefficient, explains Christophe Jost at CEE Bankwatch. But Bankwatch's report on eight national plans - Bulgaria, Czechia, Estonia, Hungary, Latvia, Poland, Romania and Slovakia – reveals weaknesses in scale, funding, strategy and policy. Many are planning to comply with only the former 40% … [Read more...]
Buildings Retrofits: inaccurate efficiency ratings are going to waste budget
Buildings renovations are going to be expensive, and complicated to roll out. Accurately predicting how much energy a building actually wastes will make that process easier and cheaper. EPC ratings are used to categorise the energy efficiency of homes. But Freya Wise at The Open University quotes research in Europe, along with her own investigations in the UK, to show that a lot of older buildings waste less energy than the standard estimates are … [Read more...]
U.S. DoE: National Roadmap for Grid-Interactive Energy-Efficient Buildings
Buildings account for more than 70% of U.S. electricity use and one-third of economy-wide CO2 emissions. Andrew Satchwell at the Lawrence Berkeley National Laboratory presents the U.S. Department of Energy’s comprehensive plan, “A National Roadmap for Grid-Interactive Efficient Buildings”, that could deliver up to $200bn in savings to the U.S. power system and cut CO2 emissions by 80m tons per year by 2030 (6% of total power sector emissions). … [Read more...]
Why expensive Buildings Renovations? By the time they’re done the grid will be emissions-free
The big budgets being talked about for the transition require us to decide how much to spend, and on what. Maximilian Auffhammer at the Energy Institute at Haas explains why he thinks a lot of the money being earmarked for buildings renovations would be better spent elsewhere. By the time the renovation wave has successfully “reached the shoreline” in the next few decades buildings will be powered overwhelmingly by clean grids (that’s the plan, … [Read more...]
How to ramp up Green Mortgages for climate-friendly house improvements
Green mortgages are used to finance climate-friendly house improvements. In the U.S. they already exist, but need to be made far more accessible and marketed widely. Greg Hopkins at RMI cites their report “Build Back Better Homes: How to Unlock America’s Single-Family Green Mortgage Market” to explain that the financial markets are looking increasingly favourably at lending that is certified as ESG (environmental, social, and governance). … [Read more...]
Buildings Efficiency in China, and what EU partners should know
To set up our upcoming online event (April 13th & 14th) "China: Carbon Neutral by 2060 -EFFICIENCY FIRST” we look at how Buildings Efficiency is being tackled by Energy Management Contracting (EMC), when an ESCO (energy service company) provides energy retrofit services and gets paid for the future energy savings. The up-front investment cost is recouped over the multi-year lifetime of the service contract by taking a cut of the genuine … [Read more...]
Energy efficiency is the “first fuel”, making decarbonisation easier for all other sectors
To set up our upcoming online event “China: Carbon Neutral by 2060 -EFFICIENCY FIRST” we look at the profound importance of efficiency to the global energy transition. Energy efficiency is the “first fuel”, meaning success here will make the decarbonisation of all the other sectors and technologies easier, faster and cheaper. Basically, use and waste less energy. Alyssa Fischer at the IEA starts by noting that their Sustainable Development … [Read more...]
Long-Term Renovation Strategies not on track to deliver climate-neutrality by 2050, indicating need for full revision of Energy Performance of Buildings Directive
A new report by the Buildings Performance Institute Europe (BPIE) finds that EU Member States continue to underplay the role of the building sector in delivering a climate-neutral Europe. … [Read more...]
Retail real estate needs Paris-Proof decarbonisation strategy to ensure contribution to global and EU emissions targets, the Buildings Performance Institute Europe says
The report marks the launch of Paris-Proof Retail Real Estate, an initiative that looks to develop a vision and strategy to support the European retail real estate sector reach net-zero carbon emissions by 2050, in line with the Paris Agreement. … [Read more...]
EU Buildings Renovations: get ready for minimum energy performance standards (MEPS)
To meet Europe’s 2030 climate targets the buildings sector must cut its emissions by 60%. That means annual renovations need to jump by an order of magnitude; at the moment it’s crawling at 1% per year. Worse, standard renovations save very little energy, just 9% in homes and 16% in commercial buildings. It’s the deep renovations that cut energy by 60% or more, but that’s only happening to under 0.3% of the stock. Louise Sunderland at RAP … [Read more...]
Policy-makers still undervalue Energy Efficiency as a grid resource
Supply-side solutions to grid stability are few in number, and expensive. More baseload generation, electricity networks, capacity markets that pay power plants all year round to be available for dispatch during a few peak hours. Demand-side solutions are usually smaller, and multitudinous: building fabric improvements, equipment upgrades, customer behaviour interventions, and more. So, for grid stability, the principle of “Efficiency First” - … [Read more...]
Five countries to become the field of behavioural experiments to encourage energy efficiency habits
The EU has ambitious targets for increasing energy efficiency and mitigating climate change, aiming that there are no net emissions of greenhouse gases by 2050. To achieve this and other targets, much effort and investment are focused on digital infrastructure (e.g., smart meters) that enables energy consumers to monitor and manage their energy usage more actively and efficiently. … [Read more...]
Buildings Renovation in Germany: success story or potential failure?
The German Federal Association of Housing and Real Estate Companies (GdW) has claimed that money and effort spent on the nation’s buildings renovations have not worked. But Andreas RĂĽdinger at IDDRI has looked into the evidence and concluded that the opposite is the case. CO2 emissions from the residential sector in 2018 were 37% lower than in 1990. Though final energy consumption was broadly stable, that’s because efficiency gains were offset by … [Read more...]
Europe’s Deep Buildings Renovations need to quadruple
The European Green Deal must grasp the opportunity to kick-start buildings renovations, says Thibaud VoĂŻta at the IFRI Center for Energy & Climate, summarising his report “The Renovation Wave: A Make or Break for the European Green Deal”. A lot of European buildings are old, and progress is slow. Stiffer regulations have helped, and household energy efficiency has risen by 30% since 2000. But the number of deep building renovations completed … [Read more...]
