I had the opportunity to work closely with the consulting team which included Bryan Flannigan and Emily Kirke throughout the program design and implementation (all while formerly with ICF Marbek). This team delivered exceptional work and provided professional and thorough results. Each member of this team provided an impressive amount of knowledge and expertise regarding upstream energy efficiency program design and delivery. The result of the work provided by the team was SaskPower’s Commercial Lighting Incentive Program which is still in market today and continues to be very successful in terms of program participation, customer satisfaction as well as energy and demand savings.

We contracted Posterity [to] assist our team for a mandate that had a very tight schedule. We were pleased with their service: they adapted to our very specific needs, met the deadlines and delivered quality work. The entire team is professional and pleasant to work with.

We hired Posterity to perform work for Natural Resources Canada. The work [required them to] collect information, analyze the data, and report on the results. They developed rigorous methodologies and quality control, and have shown dedication and creativity. The report was delivered on time and on budget. The quality of work performed by Posterity has been excellent and the interactions with Posterity have been cordial and professional. I would welcome the opportunity to work with them again.

Posterity was procured to develop new engineering worksheets for our HPNC program. I found Posterity to be professional and their work has exceeded my expectations. I would not hesitate to work with Posterity again.

– Keith Lam, Engineering Lead, Conservation Performance, IESO

[The work] required a thorough understanding of the program, the development and delivery of preliminary and final survey tools and related statistical analysis and the creation of draft and final reports. The Posterity team was highly capable, thorough and responsive and the project was delivered on time and on budget. I am pleased to provide this recommendation and will continue to rely on your team in the future.
