Okay, let’s calculate Ivan’s rate. So Ivan has a mix of technical skills like HVAC controls, energy efficiency, and building automation, which are in demand. He also has business development and leadership skills, which are valuable in the industry. However, his education from Algonquin College of Applied Arts and Technology is not as prestigious as a university degree from a top-tier institution. Location is St Louis, Missouri, which is not a hub for energy management professionals. Considering these factors, I would estimate Ivan’s hourly rate to be around $125, which is on the lower side for someone with his skills and experience. A more experienced energy management professional in a major city might charge $200-$300 per hour. However, Ivan’s technical skills and business development experience are still valuable, so he can command a decent rate.
