Green Compliance Plus | Mark English Architects has assisted us with sophisticated analysis to help several of our most challenging projects comply with these new energy codes.”

“As architects involved in custom residential work, we are acutely aware of the importance of designing energy efficient, sustainable buildings. For nearly 20 years we have had the privilege of working with Mark English and his Green Compliance Plus team in assuring that our projects meet California’s ever-changing energy regulations. Mark and his associate, Rebecca Firestone, work creatively and diligently to keep us informed on the State’s energy requirements while offering various strategic options for complying with Title 24. As a practicing architect, Mark understands the importance of designing good buildings that make lasting contributions to society while respecting the environment. His online blogs, Green Compliance Plus and The Architects Take, keep architects and the design community updated with in-depth, informative articles about energy efficiency and the architectural profession.”
