How To Engage Equipment Suppliers On Decarbonization
In this paper the iCA-EWG describes industry decarbonization efforts underway to engage our shared supply chain including the types of data that operators should request and how to evaluate the data provided by suppliers.
iCA Special Edition: State of the Digital Infrastructure Industry
This special iCA edition of the iMasons “State of the Digital Infrastructure Industry” report reframes the opportunity: not just where to invest, but where execution risk is rising and why.
Greener Data – Volume Three
We continue the conversation around sustainability, digital infrastructure, and the future of responsible innovation with a closer look at Greener Data – Volume Three.
Best Practices for Data Center LCAs
This guide provides data center developers, owners, and design professionals with how to use Life Cycle Assessments (LCAs).
Heating Emergency Power System Engines with Heat Pumps
Standby generators are an untapped source for energy efficiency. Retrofitting a high efficiency heat pump to the existing engine heating infrastructure of a genset can reduce the energy draw needed to maintain startability of the system by up to 65%.
Data Centers as Community Energy Resource Hubs: Heat Reuse for Sustainable Communities
The iCA Power Working Group (iCA-PWG) embarked on a discussion to address the challenges and opportunities presented by the iMasons State of the Digital Infrastructure Industry 2025 Annual Report.
