帝国大厦的可持续性
自建成以来，帝国大厦一直是科技、想象力和雄心的象征。通过我们行业领先的深度能效改造和可复制的操作手册，我们证明了在能源效率和可持续性方面投资的经济可行性。对此，帝国大厦的可持续性得到了独立认证，并每年重新测量。
我们的承诺
帝国大厦的深度节能改造自2007年以来使其能耗减少了38%，这得益于耗资5.5亿美元的帝国大厦恢复重建计划。该项目在现场翻新了所有6,514个窗户，并重复利用了超过96%的现有材料。自2010年以来，这座建筑每年都获得ENERGY STAR认证，使其跻身全国A类商业建筑的前20%。
可持续转型
创新、工程和经验推动了我们的节能改造，这项工程将帝国大厦转变为全球最有效率的历史地标之一，并且在全国所有A级商业资产中位于前20%或更好。
创新与工程
以效率为首要任务，我们完全改造了系统以优化能源使用。从电梯（回收原本会作为热量损失的能量）到使用反射屏障减少热量散失到空气中的散热器，一切都旨在减少我们的总碳足迹。
其中一项创新是对建筑照明系统的改造，其中包括一个根据自然光线调整的自适应调光系统。此外，建筑的许多原有照明被替换为节能灯具。
帝国大厦拥有令人惊叹的6,514扇窗户。在改造过程中，我们翻新了每一扇窗，通过现场重复利用超过96%的现有材料，将能源性能提高了四倍。
在对帝国大厦进行近一年的广泛研究和评估后，项目团队开发了一种可复制的流程以及支持该流程的工具，并成功实施了全球现有建筑中最成功的深度节能改造之一，确保实现38%的能源减少，并在2010年实施后每年得到验证和超过，回收期为三年。 我们的工作已成为纽约市、纽约州和联邦项目推动美国乃至全球能源减少和经济增长的来源。
美国环保署能源之星投资组合管理计划用于测量和跟踪能源和水的消耗以及温室气体排放。各种类型、大小和年代的建筑面积以十亿平方英尺计量进行追踪，其中只有最有效的建筑才获得能源之星认证。 帝国大厦自2010年以来每年都获得能源之星认证。 2025年，这座建筑还从LEED金级晋升为LEED铂金级，符合现有建筑：运营与维护标准的第5版，成为全国该标准中最大的项目，也是纽约州首个获得此殊荣的项目。

常见问题：帝国大厦的可持续性
Yes, the electricity the Empire State Building buys is 100% renewable, purchased as part of Empire State Realty Trust's portfolio-wide renewable supply. That sits alongside the efficiency work. The retrofit cut how much power the building uses, and renewable energy covers what it still needs.
The Empire State Building's deep energy retrofit was contracted to cut its energy use by 38%, and it has met or beaten that figure every year since 2010. Empire State Realty Trust now reports a 49% reduction against a 2007 baseline, which covers the tuning and operational work that followed the retrofit and the further energy savings it produced. The two figures measure different things: what the project promised, and where the building stands now.
The Empire State Building's energy retrofit paid for itself in three years. The work sat inside the $550 million Empire State ReBuilding program, a wider Empire State Building renovation that covered far more than energy, so the energy measures account for part of that figure rather than all of it. The process the team developed was built to be repeatable by other owners. New York City, New York State, and federal programs have since drawn on it.
Yes, the Empire State Building holds LEED Platinum certification under Version 5 of the Existing Buildings: Operations + Maintenance standard, awarded in 2025. It is the largest project in the United States certified at that level and the first in New York State. The building had held LEED Gold for more than a decade before the upgrade.
No, all 6,514 of the Empire State Building windows were refurbished on site rather than replaced. The retrofit reused more than 96% of the existing glass and other material instead of ordering new windows, to quadruple their energy performance. That is what makes the project a model for other older skyscrapers.
No, the Empire State Building doesn't claim that title. No official ranking awards it to anyone. What sets this building apart is where it started: it reached LEED Platinum as a 1931 landmark, as it refurbished what it already had rather than replace it.
Yes, you can see the Empire State Building's sustainability work in the Modern Marvel exhibit. The exhibit sets out the specific measures behind the building's sustainability and energy efficiency record. It is included with every observation deck ticket, so you can explore it on the way up.
