中国石化新闻网讯 据阿纳多卢新闻10月26日消息称，牛津大学最近的一项研究表明，全球建筑行业具有在世界几乎每个地方实现净或接近零能源建筑的技术能力，与传统建筑相比，其能源需求下降了95％。 根据研究《向全球净零建筑行业迈进》，全球与能源有关的温室气体排放中，建筑物占39%。 研究发现，虽然建筑是城市中最大的能源消耗和排放源，但却是减少排放成本最低的选择。 该研究称，通过建筑特色最大化能源效率是实现净零目标的关键，并建议使用木材和生物基产品等可再生材料来替代碳密集型水泥，以帮助减少排放。 根据《巴黎气候协定》，超过195个国家同意将全球变暖保持在1.5oC以下，以应对日益严重的气候危机。 为了实现这些气候目标，该研究提倡采取紧急行动，利用现有技术和技能，在建筑领域实现至关重要的净零排放。 研究报告的合著者、中欧大学气候变化和可持续能源政策中心主任戴安娜?厄格-沃萨茨说说：“净零能源建筑和改造在世界每个角落，所有气候条件以及几乎所有建筑类型上都是可行的。它们在许多地方已经成为市场现实，是气候中性经济的关键支柱。” 她呼吁这项技术现在成为标准做法，因为建筑库存需要几十年的时间来翻新或完全翻新，以便在本世纪中叶实现全球建筑行业的零能源。 她说：“我们建造或翻新的每一栋建筑，如果没有充分利用我们的净零技术和专业知识，就会把我们锁在一个更温暖的气候里。” 根据这项研究，可持续的建筑和能源改造也可以创造就业机会，这将是国际机构呼吁的从COVID-19疫情中恢复气候友好型经济的关键部分。 从全球来看，预计到今年年底，COVID-19的经济复苏计划规模将达到20万亿美元。 “关于气候变化问题，全世界都同意把气温控制在2摄氏度，但我们发现自己正在迈向3到5摄氏度的道路。建筑是满足世界生活质量目标和应对气候变化的核心。 曹海斌 摘译自 阿纳多卢新闻 原文如下： Net-zero buildings could reduce energy demand by 95% The global construction sector has the technical skills to achieve net or nearly net-zero energy buildings in almost every part of the world to allow a 95% fall in energy demand compared to traditional buildings, according to a recent study by Oxford University. According to the study titled; Advances Toward a Net-Zero Global Building Sector, buildings worldwide are responsible for 39% of energy-related greenhouse gas emissions. The study finds that although buildings are the largest consumer of energy and source of emission in the cities, they represent the lowest cost option for reducing emissions. The maximization of energy efficiency through building features is key to achieving net-zero targets, the study said and suggested the use of renewable materials like timber and bio-based products to replace carbon-intensive cement to help reduce emissions. Under the Paris Climate Agreement, over 195 countries agreed to keep global warming below 1.5oC to fight the growing climate crisis. To achieve these climate goals, the study advocates for urgent action using existing technologies and skills to achieve vital net-zero emissions in the building sector. "Net-zero energy buildings and retrofits are feasible in every corner of the world, all climates and virtually every building type. Already a market reality in many locations, they are pivotal pillars of a climate-neutral economy," Diana Urge-Vorsatz, study co-author and director at the Center for Climate Change and Sustainable Energy Policy at the Central European University, was quoted as saying. She called for this technology to become standard practice now given that building stock takes many decades to turn over or be fully retrofitted, in order to hit a zero-energy global building sector by the mid-century. “Every single building, we build or retrofit that does not take full advantage of our net-zero technology and know-how locks us into a warmer climate," she said. According to the study, sustainable building and energy retrofits could also create jobs, which would be a key part of a climate-friendly economic recovery from COVID-19 that international institutions are calling for. Across the world, the size of the economic recovery packages from COVID-19 is estimated to hit $20 trillion by the end of this year. "With respect to climate change, the world has agreed to a target of 2 degrees Celsius but we find ourselves on a pathway towards between 3 and 5 degrees Celsius. Buildings are at the core of meeting the world’s quality of life ambitions and addressing climate change. |
