The Advocate Dreyer Outpatient Center replaces an aging facility that no longer met the ambulatory care needs of this west suburban Chicago community. Situated just south of Interstate 88, the building was designed to be seen at high speeds from the north while projecting warm and inviting images towards the patient entrance on the south.
The building is composed of a series of tectonic planes that slide, fold, and float in order to define space, let in daylight and frame views of the surrounding context and landscape. Materials assigned to each plane were informed by the local context--precast concrete and brick--recalling neighboring buildings. Working closely with contractors and fabricators, these ordinary and ubiquitous suburban materials were elevated using simple techniques: subtle brick projections amplified by the sun; and precast concrete masonry units of varying aggregate colors and sizes, derived within the limitations of standard fabrication methods.
A cantilevered metal-clad canopy begins a spatial sequence by defining an entrance with seating that visitors pass through to enter the building. The canopy is perforated alongside a wood plane allowing daylight to illuminate the wood throughout the day. Inside, a composition of wall and ceiling planes comprising wood, glass and natural stone define waiting areas that lead to seven clinic modules, pharmacy, and immediate care center. Minimal custom signage continues the planar language and subtly enhances the intuitive and calming patient experience.
The Advocate Dreyer Outpatient Center was the first of a series of new outpatient centers for Advocate. As such, the design team established a sustainability master plan for this and all future projects, using the Healthier Hospitals Initiative, Living Building Challenge, and LEED BD+C New Construction and LEED for Healthcare certifications as guidelines. In addition, projects are designed for future expansion and include standardized clinical spaces, with reconfigurable partitions in teaming areas, to allow for future adaptability / flexibility with minimal waste and investment.
Furthermore, the team recognized the link between healthy environments and healthy communities. The biophilic design approach celebrated this commitment with elements such as an outdoor courtyard with native plantings open to the public, natural daylighting and views to the landscape from all public spaces, art that includes images of the local community, and a gallery space to displays work from local artists in the area.
The Advocate Dreyer Outpatient Center has a Predicted Energy Use Intensity (pEUI) of 64.13 kBTU/sf/year and is calculated to reduce energy consumption by 17.05% over the ASHRAE 90.1 baseline scenario. Additionally, this energy reduction translates to an energy cost savings of 17.17% over the baseline scenario. The Regional Median Energy Use Intensity for buildings of similar usage, size and fuel usage ratio is 61.0 kBTU/sf/year.
The EUI for the Advocate project represents a -5.0% reduction from the Regional Median EUI. The following energy and carbon reduction strategies were utilized to achieve this energy reduction:
- High performance insulated glass with low-e coating to reduce building cooling loads and HVAC equipment size
- LED lighting used throughout both indoor and outdoor spaces, meeting light trespass and access to night sky requirements
- Occupancy sensors in all spaces for enhanced lighting control
The Advocate Dreyer Outpatient Center provides community connectivity opportunities to enhance the visitor experience through both interior and exterior design considerations:
- Biophilic design principles incorporated throughout interior design
- Walking Score: 46
- Landscaped outdoor courtyard that provides respite space
- Preservation and restoration with native vegetation on site to promote bio-filtering of air and localized carbon sequestration
- Future expansion adaptability
The Advocate Dreyer Outpatient Center has a Predicted Water Use Intensity of 2.39 gallons/sf/year and is calculated to reduce water consumption by 21.06% over the EPAct 1992 baseline scenario. The project utilizes native vegetation and landscape that does not require irrigation. The plumbing design included a whole-building meter in addition to a water sub-meter on the plumbing fixtures & fittings branch, the domestic hot water branch and the boiler make-up water branch. The inclusion of these additional sub-meters will allow operating staff to monitor water usage periodically and identify usage anomalies that represent over-consumption, mechanical system inefficiencies, or even hidden leaks that would otherwise go unnoticed for long durations of time.
