Marcus Renner

Marcus Renner

Owner, Project Manager (BPI, LEED-AP, NCGC, MA, GPA, RWE)

With 22 years in the industry Marcus Renner has worked in most sectors of residential sustainable building. After receiving his Master’s focusing on Sustainable Building he started and operated a residential construction company for a decade. Hands on experience with new and existing construction gave him the knowledge to teach and train others about sustainable building. He became an educator and consultant and taught at Appalachian State University for seven years where he helped develop the sustainable building curriculum.

After a decade in the new construction field Marcus realized that the real battle for energy efficiency was to be fought at the existing building level. Marcus joined Conservation Pros in 2006 and helped the company grow.

In 2009, in an effort to take building performance beyond the building, he teamed up with Green Opportunities, a local nonprofit green collar job training organization. At Green Opportunities he trained and mentored underserved, low income populations through class settings, on the job experience and social enterprise guidance.

In 2013 Marcus purchased Conservation Pros. He never lost touch with the real world and still works at the ground level increasing building performance, ensuring quality and conducting research. With over 1500 buildings weatherized and 1000 energy audits Marcus and Conservation Pros bring the most experience to your home or workplace.

Harper Robinson

Harper Robinson

Project Coordinator, Web Marketing

With a B.A in Appropriate Technology from Appalachian State University’s Department of Environmental Design, Harper has been educated in building science, construction, building codes, and sustainable building design. After obtaining his degree, Harper further pursued his interest in the Dominican Republic, where he aided in the design and construction of buildings and renewable energy production.
“From learning of the world and its’ natural cycles, I discovered that I want to avoid living a lifestyle that contributes to our heavy reliance on fossil fuels. My career and the companies I choose to work for reflect this decision. I do this because I can be at peace with my life and the work I do.”

Harper volunteered for Conservation Pros for a month, where he quickly adapted and became a building performance specialist. Harper believes that as a part of this growing industry, he could have enormous potential to improve lives through educating occupants and improving indoor comfort, health, and safety while reducing environmental impacts. Harper has shown tremendous involvement with the crew as a worker and coordinator.
