Simple architectural design creates a campus of care
By Mark Robins, Senior Editor
Three years ago, a survey found there were approximately 1,100 people lacking permanent housing in Oklahoma City. That figure included 80 families and 260 chronically homeless individuals. Since then, the city’s new WestTown Campus: Resource Center & Day Shelter has provided many of them with shelter and assistance, and metal plays a major part in the structure’s success.
Oklahoma City’s homeless population face obstacles, like extreme weather, poverty, substance abuse, mental and physical health issues, unemployment, legal issues and domestic violence. For them, a new 17,000-square-foot resource shelter and 15,000-square-foot day shelter provide a “one-stop shop” for social services with multiple agencies emphasizing the values of collaboration, progress and respect. This “campus of care’s” architectural design incorporates durable materials, simple lines, sustainable landscaping and mechanical systems that minimize the expense of operations.
A renovation for respect
The resource center and day shelter used to be two existing metal building structures: a warehouse and millwork manufacturing center that had sat empty for several years. The campus is located in a blighted neighborhood just west of downtown Oklahoma City in a neighborhood with a mix of single-family housing, light industrial and commercial uses. The adaptive reuse and renovation of the existing metal buildings has provided a cost-effective, sustainable solution addressing the client’s desire to be a good steward of the funds provided by the community to build WestTown and the need to open the facility as soon as possible.
“By reusing the existing rigid steel structure, cost savings on the structural systems were funneled to upgrading the mechanical system to a single-pipe, geothermal system, which saves in operational costs over the life of the building,” says Kenneth Dennis, AIA, LEED AP, and partner and director of design at TAP Architecture, Oklahoma City. “Additionally, the existing metal roof and wall panels were removed and recycled, and the funds received were credited back to the client. Both of the existing structures received building additions to accommodate the client’s functional program. Both additions used rigid steel frames for the structural system [from Alliance Steel, Oklahoma City], which easily tie into the existing steel frames.”
In both structures, the existing steel frames were reused. However, on the north building (the resource center), the structural frames had to be removed and set aside so that the slab and structural foundation could be replaced. Both the slab and foundation on this building had failed and needed to be replaced. The existing building pad had to be excavated and replaced with compact select fill. The rigid frames were stacked neatly in a staging area while the foundation work was being completed. Once the new foundation and slab were in place, the rigid steel frames were erected.
Replacing the existing foundation and slab of the north building proved to be the greatest construction challenge. “However, the potential delay that this problem created was mitigated by the fact that we were able to reuse the existing rigid steel frames for the structure,” Dennis says. “They were conveniently staged on-site and were ready for erection when the new foundation and slab were complete.” There were no problems with the south building’s foundation or slab; therefore, their existing rigid frames did not have to be removed.
Durability, ease and speed
Metal was selected for this project because of its strength, durability and ease of construction. “As evidenced by the building’s structure, high-performance building envelope and visually striking metal panel screens, the diversity in which metal is used as a building material in this project is significant,” Dennis says. Brightly colored metal screens from McNICHOLS Co., Tampa, Fla., fabricated by Associated Steel Fabricators, Oklahoma City, and installed by Lippert Bros. Inc., Oklahoma City, highlight the central promenade.
They provide visual privacy for offices in the resource center while serving as a place to sit down and rest, or socialize. These screens also serve as sunshade panels for the windows along the south side of the resource center and help minimize heat gain. They are a real element of interest to the overall
design of the outdoor public space.
“Many of the people visiting the WestTown Campus have commented on the fun and whimsical appearance of the buildings and appreciate that they are not dull and ‘institutional’ looking,” Dennis says. Metal was used to re-skin the previous structures’ walls. The exterior walls are 16-feet-high for the resource center and 21-feet-high for the day shelter.
Using R-16, 24-gauge, ribbed metal panels from Berridge Manufacturing Co., San Antonio, and smooth metal panels from MBCI, Houston, with a variety of textures give human scale to the buildings. The ribbed metal panels were oriented horizontally so as not to accentuate the verticality of the tall walls. This creates a more intimate and familiar experience for campus visitors, particularly in the central promenade. Berridge also supplied its Zee-Lock 2-inch standing seam metal roof panels in natural white.
For all its applications at WestTown, metal offered faster speed of construction than comparable materials. “Once the building components were detailed by the fabricator and approved by the architect, they were fabricated and delivered to the job site very quickly,” says Joel Lippert, vice president, Lippert Bros. “This takes the guess work out of scheduling and erection. You know what you are working with.”
Metal security
Because the campus is a day shelter for the homeless, the design had to address the concerns of the surrounding property owners. Perimeter security fencing serves two purposes: it keeps the day shelter clients protected from outside elements (i.e. people trying to take advantage of them, sell them drugs or alcohol, etc.) and screens the outdoor activities at the day shelter from the surrounding properties.
A typical security/privacy fence constructed of stockade fence panels was considered unacceptable. But, a perimeter fence that incorporated a variety of materials including corrugated metal panels was used to produce visual screening and privacy.
“In keeping with the fun and whimsical appearance of the metal panel screens on the buildings, the corrugated metal panels are the canvas for an outdoor public art display created by members of the community,” says Dennis. “Local artists, elementary school students and corporate entities offer bright, colorful responses to the question: ‘What does home mean to you?'”
Helping people, saving energy
The buildings are energy efficient. According to Dennis, annual energy costs for the campus are approximately one-third of the cost originally budgeted by the client. “This is great because the actual cost savings realized can be used for programs to serve the homeless,” he says.
The following building systems and sustainable strategies contribute to meeting this goal:
- High-performance building envelope with spray-foam insulation and pre-finished metal wall panels, along with argon-filled insulated glazing with low-E coating.
- Single-pipe geothermal system from Climate Master, Oklahoma City, for heating and cooling.
- Placement and orientation of the windows primarily along the north and south façade; use of deep overhangs and sunshade panels/screens to minimize heat gain.
- Lighting controls utilize sensors to detect the amount of natural daylight coming into the building and adjust artificial lighting levels accordingly. Vacancy sensors automatically turn off the lights when a room is not occupied maximize energy savings.
“The single-pipe geothermal system is so simple and efficient to operate,” says John Agnitsch, Homeless Alliance facilities director. “I love it and would recommend it to anyone building a facility.”
