Three Kuhn Riddle Architects Earn PHIUS Certified Passive House Consultant Status
AMHERST — Kuhn Riddle Architects and Designers announced that three of its architects have achieved the prestigious designation of PHIUS certified passive house consultant, reinforcing the firm’s commitment to sustainable and energy-efficient design.
Thom Barry, Brad Hutchinson, and Ruoqi Zhong recently completed the rigorous training and certification process required by the Passive House Institute United States (PHIUS).
Passive house design principles focus on dramatically reducing energy consumption while maximizing indoor comfort and air quality. These high-performance buildings will also meet the Massachusetts stretch and opt-in energy codes.
By integrating passive house principles into residential, commercial, and institutional projects, Kuhn Riddle is at the forefront of designing cutting-edge, high-performance buildings that are both environmentally responsible and cost-effective in the long term.
“We are thrilled to have Thom, Brad, and Ruoqi join Garrison Piers-Gamble as our growing team of certified passive house consultants,” said Aelan Tierney, president of Kuhn Riddle. “Their expertise will help us push the boundaries of energy-efficient architecture and deliver sustainable solutions to our clients.”
