Cost: $10.3 Million
The Mead Valley Library complex provides a center for activities with a large children’s area, a multi‐purpose room for afterschool events and local events, several reading rooms, and an outdoor amphitheater. In an area where the effects of a struggling economy were evident with high unemployment, poverty, and an epidemic of crime, the Riverside County Mead Valley Library project began as a means of bringing encouragement to a depressed rural community. This library was a design‐bid‐build project consisting of a ground‐up 20,000 square foot, one‐story library complex with 3 ¼ acres of site development in the city of Perris, California. Not only was it meant to bolster and stimulate the community, but it was to become a needed center for educational benefits and community activities.
Role and Scope of Work Performed
The facility was constructed using a structural steel frame with an exterior of lath and plaster finishes. The exterior areas received new pavement, decorative concrete, and drought‐resistant landscaping. To minimize the carbon footprint of the new facility, the team assisted the county in the design and installation of several sustainable aspects. These unique sustainability features were built in to the library, benefitting the county with reduced energy consumption and maintenance costs.
‐ Underfloor mechanical distribution
‐ No mechanical units on the roof
‐ Use of photo‐voltaic (PV) panels
‐ Abundance of natural daylighting
‐ Passive shading devices designed through daylight modeling programs
‐ Bio‐swales for water filtration and reduction of storm water
‐ Use of pervious pavement in parking lot
‐ Higher reflectance materials to reduce the heat island effect
‐ Recycled content of demolition materials
‐ Low VOC paints/adhesives
One major element of sustainability came from the innovative roof. The complex roof layout was done to achieve two primary sustainable design goals. First, the roof was designed to maximize the amount of PV panels that could be placed upon it. With mechanical systems placed elsewhere, Stronghold was able to cover 40% of the roof with PV panels that produce over 65kW of renewable power. Second, the roof planes penetrate the envelope into the higher spaces and act as shading device to provide surfaces for defusing and reflecting southern and western light. Due to this careful use of architectural elements, there are no other shading devices used. This innovation was discovered using the latest in daylight modeling software and technology.
