Background With the Wasserman Football Center, UCLA wished to co-locate staff and students that were spread across campus into an advanced training facility. The project needed to represent the heritage of the program and inspire further growth. It’s aim was to enhance player development and encourage recruitment, providing for current and potential needs. The facility’s amenities focus on the wellness of both body and mind, and cater to the needs of the athletes, coaches, families, and visitors while contributing to the sustainability goals of the university.

SITE CONTEXT The University of Los Angeles is located in the urban context of the foothills in the Santa Monica mountains. Surrounding the campus is low to medium density residential housing and a small commercial center. The site is situated within the southwest region of the main campus with the longest axis of the building facing east-west. The complex is more immediately surrounded by athletic facilities. The borders interact with major pedestrian pathways running north-south and an access road. As part of the design the thoroughfare path was maintained and the experience of the approach was improved. Including the creation of a plaza at the intersection of multiple facilities to the north.

CLIMATE ANALYSIS AND RESPONSE Los Angeles has a year-round, mild-to-hot, and mostly dry climate. It is classified as a Mediterranean climate, which is characterized by seasonal changes in rainfall with a hot and arid summer. The monthly average dry bulb temperature of the the Wasserman Football Center’s location ranges from 68 - 75 degrees F. With plenty of sunlight and little rainfall, the best design strategies for this climate are internal heat gain, passive solar direct gain high mass, sun shading, and natural ventilation. The architects of the building systematically employed these design strategies through the following: 1) Creating a high-performance facade that utilizes smart shading techniques that mitigate solar heat gain while maintaining access to daylight and views 2) Using a rooftop solar thermal water heating system 3) Installing bi-folding glass hangar doors and BigAss Fans to circulate air instead of the use of air-conditioning 4) Utilizing an air displacement ventilation systems to supply sing-pass fresh air 5) Carefully choosing materials suitable for the building’s required internal heat gain, direct solar gain, and thermal mass

REGIONAL RESOURCES
Water The primary water sources of the city of Los Angeles are the Los Angeles Aqueducts, local groundwater primarily from the San Fernando Groundwater Basin, and supplemental water purchased from the Metropolitan Water District of Southern California (MWD). The water from the MWD is delivered through the Colorado River Aqueduct and the State Water Project’s California Aqueduct, sources that have historically delivered an adequate and reliable supply to serve the needs of Los Angeles City. Water is supplied to the University of California, Los Angeles (UCLA) by the Los Angeles Department of Water and Power (LADWP), which is an exclusive retailer of MWD. In fact, UCLA is the second largest user of water in the LADWP system. Throughout the years, UCLA has been exploring ways to save water. The Wasserman Football center has done this through the following:
Electricity
1) Using high-efficiency fixtures 2) Capturing and reusing greywater 3) Reducing water usage by converting the practice football field to 100% artificial turf 4) A new stormwater retention system to help manage water flow during heavy rains
California is ranked first in the US as a producer of electricity from solar, geothermal, and biomass resources. 85% of UCLA’s electrical power is produced by the 86,000 square foot co-generation plant (recycled energy) officially named the Energy Systems Facility. Off campus locations and several buildings on the southernmost part of campus are powered directly by Los Angeles Department of Water and Power (LADWP), which operates 4 natural-gas generating stations which accounts for 34% of their electricity and 19% comes from coal-fired plants in Utah and Arizona.
The Wasserman Football Center has done their part in minimizing energy consumption through smart energy by the following: 1) Providing LED lighting with occupancy-based lighting systems 2) Implementing an site solar thermal water heating system 3) Directly connecting to the campus’ central cogeneration energy plant to source chilled water and steam for mechanical uses 4) Installing a displacement ventilation system to supply air at low velocity BAP 02 | SITE | Mary Helen Kennedy & Hanna Villarosa

South-West Corner
West facade faces pedestrian walkway and has limited glazing creating privacy and protection from overheating. Most of the glazing is located on the eastern elongated face providing a connection to the football fields. The upper floors focus on wellness of the mind and the lower the body. Clerestory windows rap around at this division creating an impression that the upper stories are floating. On the ground floor retractable glass doors allow the indoor training to be accessible to the outdoor training and vis versa.

STRUCTURE The primary structural system used was metal decking. The building’s structure was comprised of metal studs, beams, girders, and steel columns. Moment connections known as structural steel moment frames (SMF) were used to combat lateral loads. A concrete foundation system comprised of built-up concrete slab on grade and concrete retaining walls (for the basement) was used.

Passive and active design strategies were used to provide thermal comfort and adequate ventilation for the training facilities. Using operable windows and large fans, ventilation and sufficient air circulation was achieved. UCLA is one of several college campuses that powers their campus using their own central plants. The building’s main way of maintaining human thermal comfort and health is through a hydronic system powered by the three-story co-generation power plant facility of UCLA known as “Co-Gen” located in the campus’ Facilities Management Building. This plant generates its own power where gas turbines powered by jet engines burn natural gas. The exhaust and BAP 06| CIRCULATION| Mary Helen Kennedy & Hanna Villarosa

waste heat from this procedure is then used to power an electric generator and produces 44.5 megawatts of electricity which is then distributed to campus and housing buildings, as well as the Ronald Reagan UCLA Medical Center. The exhaust from this procedure is then funneled through a heatrecovery steam to produce more energy, or to collect steam that is then sent to campus buildings as a source of heating. The plant also generates chill water and contains seven chillers to provide air conditioning for campus buildings. Huge pipes in the basement of the Facilities Management building (about 3 ft. Diameter) are used to circulate this water for use throughout the campus.

The UCLA Wasserman Football Center receives this water and stores it in an underground chilled water and steam vault to its east. This water is then distributed through the building and is then converted to heating and cooling, manifested in chilled beams and air ducts. Some of these systems are revealed and exposed such as the ducts found in part of the lobby and gym, while most of them are concealed such as those found in locker rooms, staff and meeting rooms, and the auditorium or viewing room

REFLECTION What may look like a simple, clean-lined building at first glance, the Wasserman Football Center of UCLA operates in ways that not only take advantage of its climate and context, but in ways that support and add value to human health, body, and mind. The building is divided into two components: the first floor as the body and the second as the mind. After studying the ins and outs of building for the past quarter, we learned how the building prioritized the service of overall human health and placed it at the center. The building reinforces the urban fabric of the campus as it is accessible from the pedestrian side and accommodates the desired program without negatively impacting campus circulation. Furthermore the building improved the pedestrian access with the building framing the passage and landscaping better defining the transition from the north to the south. The complex is generally one mass elongated with subtraction in the middle. It did not seem dynamic enough from the outside. This changed as investigated different aspects that were positively affected by a more simple and compact mass. Circulation, especially egress is clear because it generally operates along a single passage following the longer axis allowing for less space dedicated to hallways. The access in the central hallways ends in both directions with vertical circulation. These vertical and horizontal distributions of access to the user operate with HVAC distribution by flowing the same paths. The orientation increases east/ west exposure, but this was less problematic by an equally tall building shading the west orientation. Furthermore, community spaces are located to east looking on to the field, but higher east facing programs seem to be receiving glare in the morning. This is less effected by use of shading devices including the upper
Subtracted mass allowing for deck space overlooking field also increases daylight exposure especially for circulation.

floor cantilever over the lower. Overall it still seems to be a problem that could have been better solved by slightly decreasing the percentage of glazing facing the west. The subtraction in the center of the building was initially clearly an opportunity to have an overlook to the practice field below, but after looking at it again it also provides daylight to the interior hallway creating a connection to the outside even when in the center of the building. Also because of the placement of larger program spaces at the edges of the subtracted deck space it is not creating the potential problem of extreme divide between spaces that benefit from proximity to each other Using several passive design strategies and by sourcing energy locally and at the building scale, the architects were able to design the building in such a way that it uses as little outsourced energy as possible to meet peak loads. We learned how the building was able to meet the high-performance expectations of the university and commitment to sustainability through the use of a high-performance facade that regulates climate without restricting views, smart shading techniques, smart energy measures such as an on-site thermal water heating system, and a displacement ventilation system that supplies low-velocity air in lieu of a traditional HVAC system. We knew that the building was special because it appeared to showcase the modesty, power, and strength a training facility should represent through its design, however, there was much more to the building than design. Each feature was intentional and offered a part in the buildings solution and aim of obtaining sustainability and providing comfort and supporting the health of the human body and mind.
