Using a Software-Only Approach, Exergenics Enables Commercial Cuilding Cooling Systems to Perform Optimally and Consume Less Energy, Without the Need for Additional Contractors or Capital Expenditure

Exergenics’ Chilled Water Plant Optimisation Tool is a patented Machine Learning software platform that simulates plant performance under every possible condition, to produce optimised controls recommendations which can be easily programmed into the existing BMS to achieve peak plant efficiency. Leveraging operational data, the software models the actual efficiency profiles of chillers, pumps and cooling towers. This approach delivers significant benefits over using OEM performance data, which becomes less reliable as equipment performance degrades as it ages.Through a cloud-based approach, building owners can realise significant energy savings within industry-leading payback periods, without any new hardware, technicians, or workflow disruptions.

Company bio

Iain Stewart (Exergenics’ Co-Founder & CEO) began investigating commercial building air-conditioning energy efficiency in 2016 after identifying a significant efficiency gap in the operation of chilled water plant systems that led to an excess amount of energy consumption and carbon emissions.This investigation culminated in the development of Exergenics’ novel optimisation methodology for the chilled water plants, and subsequently, establishment in 2019.

Today, Exergenics is a diverse team of Engineers, Developers, and Data Scientists who share a passion for protecting the environment through the development of cutting edge technologies that enable building owners and operators to save energy, reduce carbon emissions, and enhance building sustainability and performance.

Exergenics’ chilled water plant optimisation has been an important tool in enabling us to achieve our clients’ energy reduction and decarbonisation targets. Exergenics' offering enables the capture of energy savings with short payback periods. For me, one of the key innovations of Exergenics is their ability to utilise existing building data that is already being captured to achieve meaningful sustainability change. What has been great for us is that Exergenics works with existing onsite teams, leveraging their knowledge and expertise to deliver the best possible outcome across an asset portfolio. Importantly, Exergenics’ clear process has allowed for relatively seamless implementation and pain-free integration, removing the complexity of adding opaque hardware to chilled plant systems.

Decarbonization on the WattCarbon Marketplace

James Dice

Building owners have many opportunities to decarbonize their own buildings to meet their carbon targets, but sometimes their money can be better spent decarbonizing other people’s buildings. That’s WattCarbon’s thesis, and one we believe in too. So much so that we (along with dozens of you) invested in their seed round last year.

Smart Buildings x Murder Mysteries

James Dice

Happy New Year! It’s delightful to be back at it after unplugging from work over the holidays. I needed some rest—and found it in the form of movies, TV shows, and of course, English Premier League soccer.

Invite: The Buyer’s Guide to Controls Software [Marketplace #10]

James Dice

The software operating commercial buildings hasn't changed much since before I was born. The first Building Automation Systems came about in the 1980s, with the ability to schedule equipment operation, create setpoints, and program sequences of operations. They could also store data (“trends”), display that data on a graphic, and alert operators to alarming readings (“alarms”).
