Benefit TMCx brought to the table: Phoenix Control valves scheduled on the plans did not have a specification or sequence of operation for the fume hood system anywhere in the contract documents. The design documents also failed to describe if or how the Phoenix Control system would interface with the campus LON Protocol BMS system. This was a major issue since Phoenix has a BACNet Protocol interface for connection to any 3rd party BMS. TMCx identified this deficiency of missing product specifications in their 95% CD design review phase of the project. This resulted in a number of meetings with the vendors to provide a specification before the project was let out to bid. This could have resulted in very high cost to the owner in change orders, if this deficiency was not found until after the contractor was hired. Because the missing specification was found in time, the spec was changed and the requirements included in the contractor’s scope of work package.
Project Description: The new chemical engineering laboratory is the focal point for chemistry at the University. This LEED building houses the chemical engineering and chemistry research facilities, and includes high technology energy-conserving variable volume fume hoods. The building takes advantage of 90% exposure to natural light though a day-lighting control system. The systems are designed to reduce water consumption by 30% and energy use by 21%.
Project Size: 70,000 square feet
Project Cost: $70M
Date Completed: 2010
Scope of Work: TMCx worked as the consultant for Fundamental and Enhanced LEED commissioning, hired by the University to fulfill a requirement of testing to meet the owner’s functional requirements. TMCx provided technical expertise including: extensive design reviews from schematic through construction documents, a commissioning plan, written functional and pre-functional checklists and test procedures, observation of pre-functional testing, directing of the functional testing, owner training coordination, issue resolution, O&M review, site meetings, and warranty review.
Systems: The campus central plant provides the chilled water and the steam for heating hot water heat exchangers. The laboratories, classrooms, and offices are served by variable volume boxes. In areas with laboratories, the systems have variable fume hoods with Phoenix Controls supply and exhaust tracking systems. The day lighting controls system takes advantage of the natural sunlight exposure. The air handlers have heat/cooling recovery systems to reduce the energy consumed by the large volume of outside air required by the fume hoods.
Critical Part of Building: The VAV fume hood system is a critical part of the project because of the high volume of outside air (OSA) supplied into the building. The air handlers are all 100% OSA supply and 100% exhaust air. The high-tech Phoenix fume hood control system varies the air flow to match the demand depending on how many fume hoods are in use. A conventional constant volume fume hood system provides a constant amount of air to the hood no matter how many hoods are in use. This provides a significant energy savings potential.
Project Description: The Blair International Baccalaureate Middle School design was cited for its use of natural light in classrooms, its integration of outdoor and indoor teaching environments, energy conservation, and its deliberate focus on spaces designed to create better collaboration between instructors and students. The new facility includes a new classroom building with cutting-edge science labs, art work rooms, classrooms and kitchen/meeting facilities to support Blair’s student population. To date, the new complex has won the Leroy Greene Design & Planning Award from the California Coalition for Adequate School Housing (CASH) and the American Institute of Architects, California Council (AIACC).

Scope of Work: LEED Fundamental and Enhanced Commissioning
Systems: Under-floor air distribution, chilled beam cooling, radiant under-floor heating, VAV in offices, natural ventilation through operable windows, central atrium for natural ventilation.
Sustainability: The center will strive to meet all of the ambitious but attainable goals set out for its neighbor, the award-winning environment and energy building, Y2E2. This means using 50 percent less energy and 90 percent less potable water than a standard building of its size. These goals will be met with several innovative features including:
Project Description: This central facility for the City of Los Angeles Police Department is a medium-security prison composed of a four-story building above grade with a basement and parking garage. The 512-bed jail was designed as a short-term holding center for inmates. It includes police operations, booking, food services, investigations, firing range, and other ancillary services.
Project Size: 160,000 square feet
Project Cost: $45M
Date Completed: 2008
Systems: Air handling systems are variable volume with reheat for most office areas. Constant-volume fan coils serve the interior inmate areas. Chilled water is provided by two air-cooled chillers. Heating hot water is provided by a steam heat exchanger. The facility has back-up power systems and uninterruptible power supply (UPS); emergency generators and transfer switching; and high-security alarm, paging, and communications systems.
Benefit TMCx brought to the table: TMCx found that the air handlers did not meet requirements and were found to be deficient in balancing of both chilled water supply and air distribution. One chiller did not perform and was found to be leaking oil. Once identified, these issues were corrected.
