This $180 million 250,000-square-foot six-story office complex is the first phase of a 20-year master plan to reposition every aspect of the County of Orange’s downtown real estate and approach to customer service. The Administration Building, also known as Building 16, was developed in a public-private partnership (P3). The commissioning team performed an integrated systems test at the end of the functional testing phase. The turn-key facility houses the County’s Public Works, Waste and Recycling, Treasurer-Tax Collector, Auditor-Controller, and Clerk-Recorder Departments well as a One-Stop-Shop, providing “walk-up service” from 11 departments serving the County’s constituents. The facility also features a new County Conference Center, complete with approximately 6,600square feet of conference and events space. The transit-oriented development (TOD) project will be bordered by a future transit plaza and light rail transit stop to the south, service and pedestrian paseo to the east, a central courtyard to the north a new, pedestrian-friendly street to the west. The project elevations change with solar orientation, allowing filtered sunlight to enter the east and west facades. Simultaneously, the southern exposure shields the interiors from the harsh southern sunlight, providing a highly energy-efficient aesthetic design. The building was designed to meet Essential Services Buildings Seismic Safety Act standards and Leadership in Energy and Environmental Design (LEED®) Silver certification standards. All commissioning tasks required by Title 24 Part 6 and CalGreen were needed as part of LEED fundamental commissioning except for LEED online documentation.
Los Angeles Trade Technical College modernized its 400 West Washington campus. This renovation and expansion included a new 2-story 60,000 square-foot culinary arts building with cooking labs, demo classrooms, kitchens, a servery, modular dining hall, offices, and an outdoor herb garden. tk1sc provided mechanical, plumbing, and energy & sustainability design services, which encompassed our energy team contributing to the design of the mechanical solar photovoltaic panel system penthouse rooftop connected to the existing campus solar cell system. The system generates electricity and reduces campus energy costs. In addition to the cool-roof design, this new system reduces campus energy costs and the generated power needed for air conditioning. As a result, this project achieved LEED Gold certification.
This project's sustainable elements highlight the design while also providing an efficient place for students to live, study, and socialize. With smaller than average room sizes, more common areas, study alcoves, kitchens, terraces, a classroom, and café were built with the saved space. To achieve it's LEED Gold status, our design team implemented the following sustainable building systems. Active and passive controls, motion-sensor lights in all spaces, special triggers to disable HVAC use when the operable windows are open, solar fins that shade west-facing windows for additional energy savings, and geopier footings in place of typical cast-in-place concrete, which saved time and money.Constructed on the last available parcel of campus land, the Blackstone Residence Hall was squeezed between a major college entrance, a busy street and two existing structures, with no green space on site. To make the design work, the project team employed the latest building information modeling and document-control technologies to create an angular building design that maximizes the number of units while leaving room for outdoor amenities. The result is an efficient LEED Gold building, highlighted by smaller-than-average, 150 SF dorm rooms. The saved area was allocated for more common space, study alcoves, kitchens, terraces, a classroom and a café. The 61,000 SF structure provides 15% of its area as amenity space for residents. It also created a new secondary campus entrance.

Beacon Park is the first in a series of neighborhood parks within a large-scale residential development. It is an iconic destination for homeowners and starting point for visitors. Working with landscape architects Valley Crest Design Group and architects Ware Malcomb, StudioK1 has brought magical energy to the first of multiple parks under design and construction within Orange County’s Great Park for FivePoint Communities. StudioK1 has created a night-time family playground, including the Coolest. Treehouse. Ever. Taking advantage of the multiple heritage trees throughout the park. tk1sc provided Full-service mechanical, electrical, plumbing, and Low Voltage engineering design. Mechanical Solutions: We selected the mechanical systems on the project to achieve the project goal of no rooftop equipment. The Welcome Center utilizes a VRF Heat Recovery system with an outdoor VRF unit located on grade. The fan coils are thoughtfully arranged in a mezzanine to maximize the ceiling height in the Multipurpose Room. The Multipurpose Room also featured two gas fireplaces. We closely coordinated venting solution for the fireplaces to ensure it meets the desired aesthetics from both the interior and exterior of the building. Lighting Solutions: Beacon Park is entirely lit with LED sources, allowing the design team to exceed California’s strict Title-24 regulations. We used the lighting scheme to enhance the geometry of architecture and landscape. Creating an inviting presence with warm white downlights paired with decorative pendants creates an inviting mood in the lounge-style learning space. Two different color temperatures of string lights wrap the mature trees adding to the magic. Integrated downlights within the metal trellis allow for the kitchen space to function into the evening. We lit the giant heritage trees with mid-grades from below, accenting the trunks and branches, while tree-mounted bullets are used within to illuminate the canopy. Contemporary style poles illuminate the pathways. We used asymmetric uplighting to accent the colorful decorative metal shade structures while powerful floodlights evenly light the multi-function court. Incorporating step lights into the guardrails creates a seamless look while providing light for the skywalk to the treehouse. Heritage trees salvaged from the decommissioned Marine base are now major focal points around the entire park, particularly at night with accent lighting and sparkle. The treehouse is the most eye-catching beacon of the park. LEDs create sparkle within three ancient Jacaranda trees as the steel and wood structure is highlighted with color to give it life at night. Recessed ingrade lights with the ability to change color per season or holiday create a fun light source for kids while illuminating the inside of the treehouse, making the space exciting from within and a focal point across the park. The design focused on the significant features within the park to keep the project within budget.

This project was the first of its kind for Hoag and included the nation's first ambient experience cath lab. Our scope of work on this 533,680 square foot hybrid surgery suite included all new HVAC and plumbing systems and EMS consulting services. In addition to the cath lab, this project consists of a14-bay swing Pre-Op/PACU, Physicians Lounges, Staff Lounge, Public spaces, and Exterior Entry. The hybrid operating room HVAC systems include state-of-the-art temperature and humidity control systems utilizing series desiccant wheel technology. Using the series desiccant wheel technology, low room temperatures and humidities can be achieved while also reducing cooling energy use. We also monitored hybrid OR indoor air for temperature, humidity, CO2, particle count, and VOCs. We utilized indoor air quality to monitor unoccupied air handling system setback modes to reduce energy costs further.
The UC Irvine Medical Center is a 411-bed full-service academic medical center. With plans to add a new 300,000 square foot in-patient tower to the existing 1.2 million square foot hospital, the medical center needed an additional central plant to provide a stand-alone chiller and emergency power to the outpatient services building, diagnostic and testing labs, administrative areas, and all non-acute care buildings. The new central plant's location is at a new second entrance to the medical center, a key factor driving the architectural design.

Part of a mixed-use, master-planned community, the Chino Hills Government Center was designed to be the heart of the city. The center consists of a 56,000-square-foot city hall, a 28,000-square-foot library, a 30,000-square-foot sheriff's facility, and a 15,000-square-foot fire department. A central plaza serves as a civic gathering place for the community. The project grounds itself in the local topography. Each building is anchored by extra-thick accent walls clad in natural stone. The rough-hewn material relates to the rugged hills that form a backdrop to the site. Four columns support a massive "floating" roof; a breezeway connects the city hall and library entries. The breezeway shades lobbies and frames views to the freestanding fire station on the opposite side of the plaza. For the exterior, designers chose colors typical of southwest arid regions: beige and tan, ochre and sienna.Sustainable features include daylit interiors, as well as water conservation and stormwater management strategies. The design team also incorporated a native, drought-tolerant landscape. The new government center campus includes four buildings, a City Hall (Council Chambers, offices of the City Manager, City Clerk, Building Department, Community Services, Community Development, Data Center and Support Departments), Fire Administration Headquarters, Sheriff Facility, and County Library. The Sheriff's Facility was designed to essential facility standards.
