Improving air quality

Demand control ventilation helps schools improve IAQ while keeping energy costs down


A school's ventilation needs change constantly. The more students and faculty in one area, the more fresh air is needed to provide acceptable indoor air quality (IAQ), but too much fresh air can cause energy bills to skyrocket.

That was the case for Grandview Senior High School and Meadow-mere Elementary, Grandview, Mo. Certain areas of the two schools had high CO2 levels and mold problems.

In order to fix the problem, the district's maintenance director, Herb Wilson, turned to demand control ventilation (DCV), the process of controlling the amount of fresh air introduced according to the level of CO2 in order to increase air quality in an energy-efficient manner. Lennox' L Series and S-Class rooftop units contain an intelligent microprocessor-based unit controller, the Integrated Modular Controller (IMC), that when coupled with a CO2 sensor and an economizer or motorized outdoor air damper, provide a complete DCV system.

Demand control ventilation uses a CO2 sensor to estimate the number of students in the classroom, based on the current CO2 levels, and signals the rooftop's unit controller to open the outdoor air dampers, allowing fresh air to enter the space. Once CO2 levels have been reduced, the outdoor air dampers close.

Since the new system has been installed in the schools, Wilson has seen cost efficiency improve by 20 percent.

Fighting back

Solid-colored, reinforced composite toilet partitions resist graffiti and vandalism


Academic home to more than 100,000 full- and part-time students and 6,000 faculty and staff, City College of San Francisco (CCSF) is one of California's larger community college systems. CCSF comprises more than 1.5 million square feet and more than 100 restrooms.

District architect Tobin Kendrick conducted a graffiti- and scratch-resistance test in the college's restrooms with a sample of Bobrick's SCRC, easily wiping black, permanent marking pen graffiti clean. He then directed a test of two, four-compartment, heavy-traffic restrooms serving the student union. About a year later, Kendrick concluded the SCRC material had the durability and ease of maintenance properties that met his criteria, and wrote SCRC as the college's standard specification.

His critique of prior toilet partition material began with the structural integrity of the doors, stiles and panels, and their long-term ability to support functioning partition hardware and washroom accessories.

“Metal has had major corrosion problems, thus weakening the structure. Plastic laminate has a tendency to delaminate over time, and solid plastic scars easily because it's a rather soft material,” says Kendrick.

“You don't want to just build a battleship gray room and hope that everyone appreciates it; you want to build something that looks nice with bright colors and lighting, and is well-maintained,” says Kendrick. A well-maintained facility is less likely to be vandalized, he says.

Installation system


Designed with input from professional hardware installers, the Pro-Fit Installation System reduces the time it takes to install bath hardware. Using a single-screw mounting system, the installation consists of three steps. With the mounting template, which features pre-marked pilot holes for each accessory, the installer simply places the template on the wall to drill holes, screws in a pre-attached hollow wall anchor, and clicks the bath hardware locking tab onto the mounting post.

Job scheduling

Software allows university to schedule jobs across multiple platforms and have more centralized control

UC4 Software

With its recent implementation of the PeopleSoft student module, the Computing Services Group at the University of Arkansas, Fayetteville, needed a job-scheduling solution that could integrate multiple platforms and applications.

“We wanted a vendor who was able to supply a multi-platform solution and could handle our PeopleSoft/DB2 environment,” says El Orwig, associate director of computing services.

UC4:global implementation began by converting existing jobs from the school's previous job scheduler, starting with the data warehouse jobs. These jobs were handled first because of previous problems of running processes on different platforms. UC4:global resolved this problem.

The school now can automate its technical services staff jobs — such as backup and restore functions — that previously had been done manually for the non-mainframe platforms.

“Because UC4:global divides jobs into objects, turnaround time is faster since the job plans are better handled,” says Orwig. “This has considerably reduced the amount of ‘wall-clock’ time jobs take to process, which make getting the results we want more efficient for everyone involved.”

Acoustics program


The Trane Acoustics Program (TAP), an analysis tool that helps designers model the sound level that will reach building occupants' ears, is available in a refreshed version. TAP version 3.0 automates ASHRAE-endorsed algorithms with a user-friendly Windows interface, updated product sound data, more sound elements to model sound paths, and a new report format that makes it easier to interpret analysis results. As HVAC system components are added, moved or deleted, the program recalculates the resulting sound power levels. Analysis results can be viewed as tables or presentation-quality NC or RC sound-level charts.
