Education
L&S Engineering is widely respected for its involvement with schools from its inception over 50 years ago. Well over 156 K-12 projects have been designed over the last 5 years, including 10 “4-A” High Schools. A partial listing of recent projects:

Paschal Sherman Indian School, Omak, Washington

Innovative design is the hallmark of this boarding school on the Colville Indian Reservation: Classrooms, Dormitories, and Transportation building, designed with High Performance School Standrds and LEED energy savingsd standards in mind. The mechanical systems highlighted heat recovery and shared use of components, and commissioning to achieve energy savings. Architect: ALSC Architects, Spokane, Washington

Ellensburg High School, Ellensburg, Washington

New construction: HVAC is by indoor variable air volume air handling units. Chillers and boilers provide the chilled and hot water for the air handlers. The two gymnasiums and the commons are served by single zone, constant volume systems. Shop areas are served by gas-fired make-up air units with direct expansion cooling coils and roof-mounted condensing units. Specialty exhaust systems are in place for the automobile shop, wood shop, welding shop, and science classrooms (fume hoods). Architect: Northwest Architectural Company, Spokane, Washington

Adams Elementary School, Spokane Valley, Washington

McDonald Elementary School, Spokane Valley, Washington

These two separate modernization projects were designed and constructed simultaneously. Both projects are approximately 46,000 square feet. The new HVAC systems utilize four-pipe fan coils for the classrooms, with air-cooled chillers and gas-fired boilers. The gym and commons areas are served by air handlers with four-pipe systems. Primary/secondary pumping with variable frequency drives on the heating, cooling and chilled water. Architect: Architects West, Coeur d'Alene, Idaho
