Learning Objectives

  • Digital twins, smart sensors and IoT networks in buildings can help users predict future scenarios.
  • Digital twins can give users a wider look at the energy being used in a facility or building and give users added insight.
  • 冷却技术和机器学习(ML)正在帮助创建更可持续和节能的云中心。

自1970年地球日成立以来,50多年来,地球日呼吁采取行动,解决我们最大的环境问题,这比以往任何时候都更为关键,而数字工具有助于实现可持续性、能源效率和绿色空间。今年的地球日,技术人员关注的焦点是推进向可再生能源的过渡。这包括减少信息技术(IT)的碳足迹和部署自动化工具,以减少我们的建筑空间的能源使用。

These efforts can be accomplished through new breakthroughs in digitalization and data storage. Built spaces account for40% of global energy usageand reducing their consumption must be a major focus alongside using renewable energy.

Automation innovations are ushering in a new era of sustainability. These innovations are allowing engineers, building operators and facilities managers across many industries the insights they need to slow the pace of climate change.

Digital twins provide deeper insight into energy efficiency

数字双胞胎是基于真实物理空间的虚拟环境,用于数据收集、分析和行动。数字双胞胎提供了可操作的数据,可以捕捉微观和宏观尺度的变化对真实环境的影响,让用户更准确地预测变化如何影响实际空间。

Digital twins are currently being used for efficient urban planning — seethe 2024 Olympic committeeemploying their use in Paris — and long-term global predictions, such as NVIDIA’sEarth-2 supercomputerto predict and react to the next decades of climate change.

数字双胞胎还可以用于建筑,以实现最佳的能源效率。例如,考虑一间有十几家公司的多层商业办公室。这对数字双胞胎可以从每个房间的传感器收集信息,并更深入地了解住户全天的能源使用情况,而不是查看大楼的整体电力使用情况。

这些数据可以用来预测某些变化将如何影响能源使用,例如极端温度或更高的居住量,并在问题发生之前预测问题。在现代基础设施中使用数字双胞胎,尤其是在使用智能传感器的同时,可以在城市如何智能地减少能源浪费方面发挥真正的作用。

IoT networks discover energy-saving opportunities

Software and IoT networks can intelligently act on data, whether in response to an ongoing pattern or a sudden change. Intelligent lighting is one example: does an east-facing, window-front store need to have their entrance lights on at full capacity in the morning hours? For example, a major retail chain saved more than 30 million kW hours (and millions of dollars) across all their stores by using intelligent dimming.

There are many opportunities to reduce energy consumption an IoT network can discover and automatically execute before even the most observant humans can reach their control board. This allows energy managers to focus on larger-scale issues. When small-scale changes happen automatically, such as dimming lights on sunny days, it creates more time and more opportunities for building managers to plan and innovate on higher priority items (such as incorporating environmentally friendly sources of energy). This scales users’ abilities to maximize energy efficiency in built spaces.

How cloud storage can reduce global greenhouse gases

虽然软件背后的代码与环境无关,但如何使用它对提高能源效率至关重要。对于那些希望减少碳足迹的人来说,软件是一个很容易被忽视的东西,但它有很大的全球影响。优先考虑可持续的计算和数据存储解决方案将在减少碳足迹方面起到很大的作用。

The most energy efficient storage option is the cloud, which has been shown to bethe most green data services optionover the past decade. While hyperscale cloud system use has increased over the past few years, their energy usage has not increased thanks to large investments into creating and maintaining sustainable environments for the large number of servers.

Current developments in cooling technology and machine learning (ML) will only lead to more sustainable cloud centers that can house the world’s data while reducing carbon emissions. Moving compute and data storage into the cloud is a simple, but effective, way for technologists to make a difference in carbon output.

A greener future through energy-efficient spaces

The sustainable energy journey can be expedited using innovative technologies in our built spaces. Digital twins, smart sensors and IoT networks in buildings can help us erspredict future scenarios and quickly react to emergent information. The move toward building greener data storage options will also ensure harmful emissions are reduced as software is being developed. These technologies enable users to gather more data than ever and intelligently respond to it. Using all the digital tools available will set us on the right path toward a greener future for all.
