Reduce carbon emissions9/15/2023 New buildings will no longer be heated with natural gas existing buildings need to be improved to enable fossil-free heating as well.Enhancing the energy efficiency of 1.5 million homes and a reduction of 1 megatonne CO 2 for utility buildings.The participating sectors are: electricity, industry, built environment, traffic and transport, and agriculture and land use. The National Climate Agreement contains agreements with the sectors on what they will do to help achieve these climate goals. The Climate Act calls for a 49% reduction in greenhouse gas emissions by 2030, compared to 1990 levels, and a 95% reduction by 2050. Climate Agreement to achieve reduction goals Goals and measures to reduce the emissions of greenhouse gasses within the Netherlands are laid down and agreed upon in the Climate Act and the National Climate Agreement. "We look forward to periodically revisiting this analysis to reassess where emissions from the buildings sector stand relative to the 2050 target, under both business-as-usual and more optimistic scenarios of efficient technology adoption and renewable electricity supply," Langevin says.The Dutch government is doing many things to prevent climate change. To promote the transparency and repeatability of their analysis, the researchers have published their efficiency measures and results data, all generated using Scout, a model that is annually updated to reflect key changes in the building energy use and electricity supply landscapes. "Regulations and incentives that support the sale of more efficient, less carbon-intensive technology options, early-stage research and development that drives breakthroughs in technology performance, aggressive marketing of those technologies once developed, training for local contractors charged with technology installation, and consumer willingness to consider purchasing newer options on the market are all needed to achieve the 80% emissions reduction goal by 2050," says Langevin. The researchers stress that bringing these strategies and emissions benefits to fruition is contingent upon complementary action by policymakers, manufacturers and vendors, building service professionals, and consumers. The second focuses on smart software that is capable of optimizing when, where, and to what degree energy-intensive building heating, cooling, lighting, and ventilation services should be provided. The first involves energy-saving retrofits and upgrades to walls, windows, roofs, and insulation - the so-called building "envelope" - approaches that can also boost living and working comfort for building occupants. Moreover, buildings can support the cost-effective integration of variable renewable sources by offering flexibility in their operational patterns in response to electric grid needs."Įxamining results for specific efficiency measures, the researchers identified two particularly promising avenues for reducing emissions. "Getting close to the 80% emissions reduction target requires concurrent reductions in building energy demand, electrification of this demand, and substantial penetration of renewable sources of electricity - nearly half of annual electricity generation by 2050. "While building CO 2 emissions are quite sensitive to the greenhouse gas intensity of the electricity supply, measures that improve the efficiency of energy demand from buildings need to be part of the solution," Langevin says. They also considered how parallel incorporation of renewable energy sources into the electric grid would shift emissions reduction estimates from each building efficiency measure and the buildings sector as a whole. buildings sector over several decades, the researchers considered three types of efficiency measures - technologies with higher energy performance than typical alternatives, such as dynamic windows and air sealing of walls, sensing and control strategies that improve the efficiency of building operations, and conversion of fuel-fired heating and water heating equipment to comparable systems that can run on electricity. To estimate the magnitude of possible CO 2 emissions reductions from the U.S. "Because the buildings sector uses energy in a multitude of ways and is responsible for such a large share of electricity demand, buildings can help accelerate the cost-effective integration of clean electricity sources on top of contributing direct emissions reductions through reduced energy use." "Buildings are a substantial lever to pull in trying to reduce total national CO 2 emissions since they are responsible for 36% of all energy-related emissions in the U.S.," says Jared Langevin, a research scientist at Lawrence Berkeley National Laboratory and lead author of the study.
