Okay, let’s tackle this. So Terry has 30 years of experience in architecture, which is a significant amount. His skills in sustainable design, green building, and LEED are in high demand. He has worked in two prominent architecture firms, which suggests he has a strong network. Location is Austin, Texas, which is a growing city with a strong demand for sustainable architecture. Considering his experience, skills, and location, I estimate his hourly rate to be around $125, which is slightly below the national average for architects in the US. This is because Terry is an owner at his current firm, which might impact his compensation. However, his experience and skills still make him a valuable professional in the field.
