La Escuelita Education Center
Case Study No. 13
Data Summary
Building Type: K-12 Education Location: Oakland, CA
Gross Floor Area:
Phase 1 (ZNE) 58,498 gsf Phase 1 (Non-ZNE) 13,070 gsf
Primary and secondary school education facilities (known in short as “K-12 schools”) make up a common building type with similar building program elements, and therefore constitute an informative case study with general application. Public K-12 schools are also highly regulated and have design standards for systems and environmental characteristics that have widespread acceptance and application. This case study illustrates not only possible transferable design strategies for other K-12 projects but also the particular constraints on the design process that affect the choices of those strategies.
Background
In 2006, the voters of Oakland passed a local bond measure that included $75 million in project cost for the replacement of a collection of K-12 school buildings that were seriously deficient and in need of modernization. Located near downtown Oakland and adjacent to Laney Community College, the site included an existing elementary school, a high school and two child develop- ments centers. (See the aerial photo of the existing site conditions, below.)
In addition to the elementary school (“La Escuelita Elementary School”), the secondary school (“Metwest High School”) that were already on the site, the program for the new campus was expanded to include a large multipurpose room (“The Great Room”), a health clinic, a combined child development center (“CDC”), a data center and a TV studio (“KDOL”) for the District.
To accommodate such a varied program of almost 120,000 sq. ft., and to minimize disruption as well as cost, the program called for two phases of construction. Phase 1 would be built on the north half of the site and would include principally the elementary school, the Great Room, the health clinic, the data center and TV Studio. Phase 2 would follow on the south half of the site, comprised of the high school and the child development center.
