At the time, Wright-Ryan had just fi nished the Passive House Village Centre in Brewer. e decision wasn't diffi cult. "It focuses more on energy use, not where did your trusses come from," she says. e private school of about 550 stu- dents agreed energy savings meant more money could go into education. Besides the Brewer and Waynfl ete projects, Wright-Ryan managed con- struction on the 5-unit Bay Anchor, which was completed last year. Warren Construction Group, based in Freeport, is another fi rm building to Passive House standards, including the $2.3 million Friends School and the $6.3 million high school addition at Maine Coast Waldorf School in Freeport. At Waynfl ete, director of marketing and communications Rand Ardell and project superintendent Millard Nadeau, of Wright-Ryan, point out the features of the planned addition, including dif- ferences between Passive House and standard construction. e wall insulation panels are more than eight inches thick and spray foam provides a vapor barrier at connection points. e roof insulation is 16 inches, nearly triple the standard of six inches. Equipment in the ceiling provides ven- tilation while keeping the temperature moderate. Triple-pane windows are placed for maximum sun exposure. e building will be heated by heat pumps. "It's more effi cient, you're not using oil or burning natural gas," Nadeau says. e addition was angled to capture the sun. Recent surge Maine's Passive House pioneer was Unity College, where in 2011 G-O Logic of Belfast built a 2,100-square-foot resi- dence that houses 10 students, Terrahaus. e 15,500-square-foot Friends School was built in 2015. Since then, there has been a surge of Passive House commercial projects, including -unit Village Centre in 2016; the Maine Coast Waldorf School high school addition in 2017; 5-unit Bayside Anchor in 2017; and Cornerspring Montessori School in 2017. ยป C O N T I N U E D F RO M P R E V I O U S PA G E DESIGN | BUILD | MAINTAIN BUILD EXCELLENCE WITH PRIDE PROUDLY SERVING THE CRAFT BREWING INDUSTRY BREWHOUSE INSTALLATION FERMENTATION TANK INSTALLATION FILTRATION PIPING PROCESS SKIDS VALVE MANIFOLDS CIP SYSTEMS CCB INC 65 Bradley Drive Westbrook, Maine 04092 Tel 207.464.2626 Fax 207.464.8374 www.ccb-inc.com COMPLETE TURNKEY SYSTEMS & CUSTOM DESIGN/BUILD MAINE COMMERCIAL PASSIVE HOUSE PROJECTS Terrahaus, Unity 2011 / Unity College residence Architect: G-O Logic, Belfast Builder: G-O Logic, Belfast Size: 2,100 square feet Cost: $451,500 Friends School of Portland, Cumberland 2015 / School Architect: Kaplan Thompson Architects, Portland Builder: Warren Construction Group, Portland Size: 15,500 square feet Cost: $2.5 million Village Centre, Brewer 2016 / 48-unit apartment building Architect: N/A Builder: Wright-Ryan, Portland Size: 51,778 square feet Cost: $7 million Bayside Anchor, Portland 2017 / 45-unit apartment building Architect: Kaplan Thompson Architects, Portland Builder: Wright-Ryan, Portland Size: 36,161 square feet Cost: $7.8 million Cornerspring Montessori School, Belfast 2017 / School Architect: G-O Logic, Belfast Builder: G-O Logic, Belfast Size: 6,100 square feet Cost: $1.18 million Maine Coast Waldorf School high school, Freeport 2017 / School Architect: Briburn, Portland Builder: Warren Construction Group, Portland Size: 10,216 square feet Cost: $6.3 million Waynflete School, Portland Summer 2018 / Addition to school Architect: Scott Simons Architects, Portland Builder: Wright-Ryan, Portland Size: 30,000 square feet Cost: $12 million (includes renovation of connected building) S O U R C E : PHIUS Certifi ed Projects data- base, news reports, organization websites
