James Nostedt

In 2019, Jim retired from the Royal Canadian Air Force as the Sustainability Manager.  Immediately after retiring, Wayne Cole of SRP Canada asked him to continue developing the SEEFAR Building Analytics Inc. 

Read More about James Nostedt

SEEFAR’s business focus is to improve the sustainability of new and existing buildings.  SEEFAR-Valuation© is a program that compares the Total Cost of Building Ownership (TCBO) of low first cost code buildings to High Performance Buildings (HPB).  HPB use over 80% less energy, have a longer life and are more comfortable to live in.  In addition, our analysis shows that HPB have a dramatically lower life cycle cost or lower TCBO.  When people can see that HPB have significantly lower costs they are more lightly to build them, which will reduce our greenhouse gas (GHG) emissions.   These same TCBO principles can be applied to retrofitting existing buildings..

Jim has a Bachelor of Science in Mechanical Engineering (1976) degree from the University of Manitoba.
