Tip for Building Efficiency

Monday, August 31st, 2015

Ventilation air can constitute a large portion of an overall energy bill. In some buildings, it can be as high as 30% of the cooling load and 60% of the heating load. Are you finding your energy bills to be too high?

One way Egan can help you reduce this cost is to employ Demand-Controlled Ventilation (DCV) through your building automation system. A DCV system can be retrofitted to a building or utilized in new construction.

A DCV system uses carbon-dioxide sensors located within the building. These sensors are used to estimate the minimum ventilation requirements needed for occupants. If carbon dioxide levels rise—and they will as more people enter the space—the ventilation system opens and allows fresh air to enter for proper ventilation.

Utilizing a DCV system yields a huge potential for energy savings, especially in building zones where occupancy levels vary widely. When occupancy levels are low, the outdoor ventilation rate can be reduced to minimal levels and eliminate the need to condition additional outdoor air. Building zones such as auditoriums and conference rooms are prime examples.

If you’re looking to lower your energy bills, contact your representative to see how Egan can help.

Valuing a Trusted Partnership

Wednesday, August 26th, 2015

DSC_0708_editAnoka-Hennepin School District #11 (A-H) is one of the largest in Minnesota, encompassing 45 schools and close to 39,000 students (or about 5% of total public school enrollment in the state). For the past 27 years, Egan Company has been the district’s sole integrator of building automation systems.

Building automation allows owners to control nearly all aspects of a building that regulate energy usage, affecting everything from operational costs to carbon footprint. As new technological features have evolved, Egan has worked with A-H to bring each school facility to the next level of energy management sophistication, dating back to when the technology first surfaced in the early 1980s.

But 27 years is a very long time to be in business with a single contractor. How can this kind of relationship endure for so long?

“There has always been a need to manage HVAC systems efficiently,” said Roger Wood, Anoka-Hennepin Schools Maintenance Supervisor. “Egan collaborates with us to help create a healthy classroom environment for students and staff, while at the same time managing our HVAC systems to be very energy conscious.”

Over the years, Egan has become tremendously hands-on and knowledgeable of A-H’s overall needs, and that reflects in the way we do business. Years of service calls, updates, and maintenance requests have required Egan personnel to look at the big picture to keep A-H’s facilities running smoothly.

“Trust is the key to how we maintain business relationships,” said Tom Addabbo, Egan Company Account Manager. “We continuously show that we are invested in helping the customer achieve his/her goals, and that leads to deep-seated trust over time.”

Deep-seated trust is not fostered overnight, and it can be especially hard to maintain in a public school system, where decisions are committee-led and opinions are subject to change as new members are elected. But it certainly is possible to achieve, so long as both parties recognize each other’s own vested interest in succeeding, which sometimes means going beyond expectations.

– Tom Addabbo, Egan Company Account Manager

A few years ago, Rum River Elementary was experiencing issues with a converter valve sticking open (causing the building’s boilers to overheat). Gary Schultz, Egan Company Technician, received a call at about 4 p.m. the Wednesday before Thanksgiving. He was about to leave for a holiday dinner.

“Roger [Wood] called me and explained the situation,” said Schultz. “I could have gone home, but I felt it was not the type of problem you leave over a long weekend.”

Schultz pushed back his holiday plans and set out to Rum River Elementary to help fix the valve issue, which was eventually resolved later that night.

DSC_0710_editHis actions that Thanksgiving represent one of many moments where Egan technicians have delivered on a personal commitment to ensuring success for our customers.

“[Egan has] provided us with a high level of expertise and customer service,” said Wood. “Whenever there is an issue Egan responds promptly with technicians who are very knowledgeable and respectful.”

Whether that means working unconventional hours or even addressing issues that weren’t necessarily Egan’s to fix, the goal is to ultimately save the customer costs in energy usage and hassle. For partnerships like this one, there’s much more to performing the service than merely meeting a budget – there’s character, loyalty, flexibility, and reliability. Any construction-related project can turn south quickly if trust isn’t valued, and though you can’t add “trust” on a pricing sheet, it’s as real as any other line item.

Compressed Schedule Calls for Cross-Trade Coordination

Saturday, September 20th, 2014

lakes_internationalThe side-effects of the deluge of rain we received this last spring are still being felt today. On top of flooding and lake closures, there was a direct impact on construction projects that had to push back start dates because of wet soil.

New building construction for the Lakes International Language Academy (LILA) adopted an aggressive new timeline to combat this obstacle. The K-6 charter school looked to build upon the success of its tuition-free immersion program (Spanish or Chinese) that follows an accredited International Baccalaureate Primary Years curriculum in the form of a new facility.

The rain, while good for flowers, turned the work site into a challenge. The foundation’s soil turned to soft clay, making for a less-than-ideal work environment. In fact, a concrete composite had to be mixed into areas where soil integrity was most vulnerable, effectively turning the school’s new parking lot into a great big cinder block.

highres_lakes_smallerEgan’s Electrical, Mechanical, and Building Systems & Services groups partnered with general contractor Kraus-Anderson to find a way to get the job done on time.

Collaboration between Egan and Kraus-Anderson’s Project Manager Jake Boerboon and Superintendent Jesse Fiskewold were essential to project success. Even closer coordination was required than is customary for a project like this. Potentials for lost-time or further delays were addressed and resolved before the fact, creating an extremely well-organized work model.

Design/Build was also a huge factor in facilitating the accelerated timeline. Thanks to Egan doing the design and construction, many issues were resolved before they could reach the field. Without this, on-site problem solving would be a necessity and could have delayed the project further.

The construction team benefited greatly from prefabrication on this project. Circuits and feeders were crafted in-house and pre-assembly of the duct helped reduce installation time in the field. Close coordination between mechanical and electrical also minimized penetrations in the precast and allowed coordination of hanger systems, nearly cutting the initial estimate time in half.

Egan also supplied the academy’s building automation system. The weather delay shortened the installation timeframe significantly, requiring work to be completed in about a week.

The project finished on time, giving the school about two weeks to furnish and organize the building to be student-ready for the Fall.

The Lakes International Language Academy Project is a newly constructed, 43,000 square foot, two-story facility that included two parking lots and a gymnasium. The building’s automation system included integrating seven Lennox RTUs, installing controls on VAV boxes, and interlocking the kitchen make up unit with miscellaneous exhaust fans.

Summer of School Upgrades and Installs

Friday, September 19th, 2014

anoka-hennepin-school-outsideEvery summer, Egan Company’s Building Systems & Services (BSS) group upgrades or installs new building automation or fire systems in schools across Minnesota and Wisconsin.

Egan completed work this summer in over eight school districts, including St. Paul Public Schools, Eden Prairie Schools, Anoka-Hennepin School District, School District of Clear Lake, and St. Michael-Albertville School District. All of this work is compressed into a three-month timeframe and equates to over 20,000 hours of manpower.

The building automation system controls everything from air handling units to VAV boxes to pool converters to lighting. Many schools also incorporate energy efficient systems to produce lower utility bills. The fire systems in the schools provide smoke management systems, advance detection, voice evacuation and exit technology, and sprinkler system monitoring.

The installation of these two systems can prove challenging, especially in such a short timeframe; however, Egan simplifies the project process by providing system engineering, design, installation, and start-up and commissioning to finish the job quickly.

All systems were updated before school started this Fall. Year round, Egan also provides maintenance to these–and other–school districts.

“Every summer we roll up our sleeves for various schools,” said Tom Addabbo, Egan Account Manager. “It’s always a challenge to help bring these schools back online before the school year starts. Fortunately, our field team does it year after year and knows what it takes to meet these tight timelines.”
