Sustainability that enhances curriculum
The new Advanced Technology and Applied Science (ATAS) building at Saddleback College is a 52,100 SF facility that supports multiple modalities of learning (visual, auditory, kinesthetic, tactile) in career technical education (CTE) and more traditional disciplines. The design of the ATAS building showcases the diverse curriculum provided by the architectural drafting, computer technologies and maintenance, graphic design and communication, environmental sciences, marine biology studies, advanced manufacturing, and horticulture departments.

Exposed building systems and transparent maker and exhibition spaces invite students to encounter ideas beyond their own curriculum. Maker spaces are located for maximum accessibility and deep connections to other disciplines and the natural environment. The design team used the building design as a teaching tool to demonstrate how built and natural environments can incorporate sustainable designs. Structural and mechanical elements are exposed throughout so students can see the thickness of the concrete walls and floors and understand the importance of thermal mass and night-flushing for reduced cooling loads. Daylight harvesting brings natural light deeper into the classrooms while reducing heat gain with sunshades strategically located on the south facing windows.

Water efficiency was designed using a local water-filtration garden. Stormwater management channels with grass swale are located throughout the stepped landscape garden where California native plant species have been selected to increase the educational value and relevance of these gardens for horticultural, environmental science and other campus department curriculums.
ATAS is designed to be LEED Gold equivalent.
The solar array is designed with a capacity to achieve a 35% improvement in the proposed building performance compared with baseline.
Predicted Energy Use Intensity (PEUI) for the building is 56 kBtu/Sf/year. This is 73% reduction from the baseline used by AIA Architecture 2030 challenge.
The window-wall ratio of this building is 34.3%, keeping it under 40% to promote thermal efficiency.
The double story main lobby has a view of courtyard and stepped landscape with California native plants such as coastal sages and other low water demanding chaparrals.
Saddleback College's ATAS Building has been selected as a 2023 winner in the DBIA's Western Pacific Region annual Design Build Awards Program.
