Shaping Tomorrow's Built Environment Today
March 21, 2024
The top-hatted “drinking bird,” once a fixture in science classrooms for demonstrating the basics of thermodynamics, is making a surprising comeback as the inspiration for a new clean-energy generator that could one day power your watch and phone. Scientists in Hong Kong and China have used the famous toy to develop an engine capable of using the power of water evaporation to generate electricity, according to a study published on March 14. The new method works by converting the energy produced by the bird’s characteristic back-and-forth movement into electrical power. Read more

In the current landscape dominated by AI-driven applications and dense chip architectures, liquid cooling has emerged as a pivotal technology. The shift from general-purpose computing to a more specialized, purpose-built infrastructure is driving the need for advanced cooling solutions, particularly in high-density deployments like GPU clusters, pods and modular data centers. These systems, crucial for efficiently managing the substantial heat produced by densely packed CPUs and GPUs, are now a fundamental part of modern data center design. Liquid cooling technology now emerges as a key player. Read more
Vulnerabilities affecting Linear building access products, including a security flaw that has been exploited, have been patched nearly five years after their initial disclosure. In May 2019, Gjoko Krstic, a researcher who at the time worked for industrial cybersecurity firm Applied Risk, disclosed information on more than 100 vulnerabilities found in building management and access control systems from Nortek, Prima Systems, Optergy and Computrols. Read more

An underused portion of ASHRAE’s Thermal Guidelines for Data Processing Environments, 5th Edition, is the analysis of server reliability data and the impact this can have on both the energy consumption and the capital cost of a data center. This reliability analysis is called “x-factor” and is the focus of Section 2.4.3, Server Reliability Trend Versus Ambient Temperature of the Thermal Guidelines’ 5th Edition. Download here
Abstract submissions are now being accepted for the 2025 ASHRAE Winter Conference to be held in Orlando, Florida, February 8-12, 2025, at the Hilton Orlando. Read more

Amazon Web Services (AWS) has secured a nuclear-powered data center campus as part of a $650 million agreement with Texas-based electricity generation and transmission company Talen Energy. AWS’s acquisition includes the Cumulus data center complex, situated next to Talen’s 2.5 gigawatt Susquehanna nuclear power plant in northwest Pennsylvania. As part of the agreement, Talen will continue to supply Amazon with direct access to power produced by its Susquehanna nuclear power plant, which could reach heights of 960 megawatts in the coming years. While nuclear energy may be a controversial power source, AWS’s acquisition aligns with its commitment to carbon-free and renewable energy sources.  Read more
