Camas School District: Lacamas Heights Elementary Modernization
Background
Camas School District planned a renovation of Lacamas Heights Elementary, one of six primary schools in the District. The project, which began in March 2013 and includes a number of energy efficiency initiatives, resulted in an energy savings of 19% and cost savings of $11,000 annually.
The primary school was built in the mid 1960’s and is composed of five stand-alone masonry buildings, an administration building, and two portable buildings at the school.
Solutions
The overall project consists of a number of efficiency upgrades including the refurbishment and improvement of the HVAC systems serving the POD areas (modular classrooms) and replacement or upgrade of most of the HVAC systems serving the main school building and offices. In addition, the control systems will be modified to improve comfort and reduce energy usage throughout the school.
