Prism offers engineering and construction project management services for the implementation of energy retrofits, often based on the concept designs developed in our Energy Audits.

Unlike new construction, retrofitting existing buildings with energy and carbon reducing technologies comes with its own set of unique challenges. Since 1990 Prism has focussed our design and retrofit work on existing buildings, developing unique expertise in how to integrate innovative technologies into existing building systems.

Where possible we try to re-use as much of your existing building infrastructure as possible as part of our retrofits, reducing construction waste and lowering costs.

Our team of building controls experts is involved in all retrofit projects, recognizing that to maximize project savings the way in which building controls are optimized is critical.

We are committed to making sure retrofit projects get done right. To do this we stay with you until the very end, ensuring that retrofits are commissioned properly, contractor deficiencies are addressed, and staff are trained on how to operate and troubleshoot new systems.

The graphic below outlines some of the key considerations encountered during retrofit projects. Prism provides solutions to help address these considerations, overcome barriers, and ultimately ensure the success of the project.
