Big Ten & Friends Utilities Conference

Big Ten & Friends Utilities Conference

Applied recently joined with some of our University partners to discuss campus utilities, energy processes and energy distribution at the Big Ten & Friends utilities conference at Purdue University.  The event kicked off on a Sunday afternoon with a golf scramble at the Birck Boilermaker Golf Course, which we sponsored. The weather cooperated and there was great fun had by all. Sunday night wrapped up with a welcome reception and dinner. Networking between vendors, universities, facility engineers, and design professionals took place.

Monday and Tuesday brought subject matter experts together to discuss how to improve energy distribution, save money on the production of steam and chilled water, and help create a green environment and better place for us all to live.

Jim Lowe, Associate Vice President for Facilities Planning and Management at Ball State University, provided an update on BSU’s conversion from steam to geothermal water distribution. Jim noted that BSU has been seeing a consistent annual payback of $2.2M, which puts the project payback at 10-12 years.

Amanda Doenges, Director of Engineering and Administration at Butler University, and Taylor Smith, a graduate from Butler University’s Engineering Dual Degree Program, presented on electric sub-metering and energy management. The two discussed how metering can help provide knowledge on where energy inefficiencies can be reduced. Through data, a facility manager is able to review utility demands to find ways to increase energy efficiencies of processes.

We at Applied enjoyed seeing many friends and clients visiting our exhibit booth! Our firm regularly engineers utilities projects for local universities, in addition to our mechanical, electrical, and plumbing designs. It is always wonderful to make new connections, and sharing our knowledge of utilities for higher education environments with the network of facility individuals at the conference was very rewarding. Hopefully Big Ten & Friends will return to Indiana soon!

Purdue Technology Center Aerospace Building Dedication

We recently had the honor of attending the building dedication for the new Purdue Technology Center Aerospace Building. Applied was responsible for engineering the mechanical, electrical, and plumbing for this new 55,000 SF, two-story facility, with a $12 million construction cost. Rolls-Royce is occupying approximately 60% of the space, and we helped design their test cell facility where jet engine components will be designed, developed, and tested. The Aerospace Building is also the new home to Purdue’s Physical Facilities Department. Dan Hasler (President, Purdue Research Foundation), Mitch Daniels (President, Purdue University), Marion Blakey (President and CEO, Rolls-Royce North America), Senator Brandt Hershman, and Mayor John Dennis (City of West Lafayette) all spoke during the dedication. Adding to the excitement of the day was the flyover and landing of an MV-22 Osprey.

Purdue Bound Career Day

Purdue Bound Career Day

The Saturday morning started out cold, but the Purdue Bound (formerly Science Bound) Career Day kicked off with great warmth as the excited students learned about jobs and opportunities within STEAM (science, technology, engineering, agriculture, and math) fields. Applied Engineering Services served as a corporate sponsor for the event, along with Purdue University, Raytheon, Bowen Engineering, Rolls-Royce, Dow AgroSciences, and Eli Lilly and Company. Each firm gave the students a quick “day in the life” of an engineer, scientist, designer, researcher, or programmer.

Mike Jamieson and I talked with students about the type of work Applied does within the consulting engineering industry. We described how Applied utilizes engineering knowledge to provide HVAC designs, plumbing design, power distribution, and telecommunications connectivity, and how our work utilizes math, science, and engineering, and technology to create warm and inviting environments. We gave a broad overview of healthcare design to the students, touching on how HVAC designs can be best implemented to reduce the spread of infections in hospitals. Power distribution from the utility company down to the receptacles was also generally described.

The students were actively engaged with some of the hands-on devices that we demonstrated. Mike described energy efficiencies in the HVAC realm by showing how a small ventilation recovery device works and how sensible and latent energy is transferred through the cross-baffle heat recovery membrane. The plate and frame heat exchanger spurred several questions from the students. On the electrical side, the manual motor starter and medium voltage cable drew the most interest. I helped break down the electrical concepts behind the equipment, which allowed the students to better understand how the parts and pieces all work together to create a complete building system.

The morning included a panel discussion with previous Purdue Bound graduates describing their college and life experiences, and wrapped up with a motivational speech by Purdue All-American Running Back LeRoy Keyes and his wife, Monica. The students and career volunteers noted that it was a great experience, and everyone appreciated Rolls-Royce’s hospitality in hosting the event at their facility.

Science Bound Parent Meeting

Applied Engineering Services is a long-time partner of the Science Bound program, a Purdue University/Indianapolis Public Schools partnership where a student who successfully completes the program is given the opportunity for paid tuition at Purdue University. We have supported Science Bound for nearly a decade as an advisory board member, at the annual career fair, through summer internships of rising high school seniors, and financially.

Recently, I met with the parents of Science Bound students to describe what it takes to be an engineer. We discussed the various types of engineers, the importance of writing, spelling, and communications skills in addition to the typical math and science courses, good study habits and time management, and the importance of being a leader through extracurricular activities.

The meeting wrapped up with a discussion on the commitment required to be successful in the engineering program at Purdue University (ranked 6th in the nation and 26th in the word for engineering schools according to US News and Word Report). Engineering school requires hard studies and every student has to want it/earn it. Getting practical experience during college, through internships and co-op programs, is also a must for the graduating engineer.

Day in the Life of an Onsite Project Engineer

Day in the Life of an Onsite Project Engineer

Loren Horan DITLHave you ever wondered what our engineers actually do all day? This year, we’re continuing our “Day in the Life” series started in 2014. Each quarter, we will feature someone within the firm who will provide insight into their typical day. This quarter showcases one of Applied’s owners, Project Engineer Loren Horan, PE, RCDD, LEED AP.

As a project engineer, my day is typically laid out in one of the following three ways. The first option is a day in the office where I work on designs, specifications, review shop drawings, collaborate with team members, and perform engineering calculations. The second option is a day where I am in the field to attend construction meetings, observe construction in progress, perform a site survey for a new project, meet with clients to determine their needs and requirements, and collaborate with architects, structural engineers, and civil engineers at their offices. The third option is somewhere in between the first two. I chose to write about a day where I was onsite.

7:00 am – My day starts as I leave home directly for Purdue University.

8:30 am – Arrive at Purdue University and head over to Lynn Hall to start our observation of the sprinkler system hydrostatic pressure test. I meet the contractor and owner at the site and we watch each sprinkler zone get pumped up to 200 psi of hydrostatic pressure and confirm that there aren’t any leaks.

9:00 am – The pressure gauges on the sprinkler zones have been initially recorded.  I now walk around the building to perform my construction observation.

9:30 am – Stop in at a student commons area to get a cup of coffee and open up my computer to respond to emails. I am able to remotely connect into the office, so I am also able to perform some lighting design and calculations for an industrial client.

11:00 am – Meet up with the contractor and owner to review the pressure gauges and confirm that the sprinkler lines are still holding the same pressure.

11:30 am – I have a few minutes before my lunch meeting, so I work on some specifications for an industrial client that is creating a new headquarters within Indianapolis.

12:00 pm – Have lunch with an architect that we are working with on some classroom renovations. We catch up and review the submittals that have been issued to date on the first classroom project. We also discuss a recent change request by the owner to add some art to the second classroom project.

1:30 pm – Attend a pre-construction meeting for the second classroom project. I see familiar faces, such as the Purdue University project manager and building deputies. During this meeting, the owner describes their construction and safety requirements. The design team and contractor coordinate on how submittals will be issued.

2:30 pm – The pre-construction meeting ends and I head to a planning committee meeting for the new Innovation Design Center building. During these collaborative meetings, the clients and design team review the block layout of the proposed spaces. The design team accepts feedback from the clients and interviews the users to better understand their needs and the intended practices of the space.

5:00 pm – The planning committee meeting concludes and the architect and I have a quick 5 minute recap to ensure that we are on the same page. I check my email to determine if there are any high priority items that must be addressed prior to heading back to Indianapolis.

5:15 pm – I get into my car and leave Purdue University, ending my work day.

Farewell to the Purdue HPN

Posted on: 1 Comment

Farewell to the Purdue HPN

To make room for the new Active Learning Center, Purdue’s Heating Plant North (HPN) is slated for demolition. While they still had the chance, three of Applied’s Principals – Frank St. John, Terry DeBoo, and Ralph Power – recently toured the HPN, learning about its history and the critical role it used to play on campus. Below is Ralph’s take on the tour of this iconic 90-year-old facility.

The afternoon before the Purdue-Michigan basketball game, lost in the final half-second of overtime, a small group of us toured Purdue’s Heating Plant North. This beautiful facility in the heart of Purdue University’s campus was built for the expanding campus circa 1923 and was decommissioned in 1986. Over those 60+ years, this plant – with its iconic illuminated smoke stack – provided heating and electricity to serve the campus via a beautiful tunnel system.

What we saw with a little imagination was an era gone by, where a half dozen coal-fired, multi-story steam boilers were fed by an overhead coal bin on rails. These powerful yet simple machines were manually operated day in and day out by the very skilled craftsman of the day. The controls were minimal and simple.

While the top of the smokestack was removed brick-by-brick in the late 1990s, the massive base is still in the plant. The remnants of the coal ash cart and rail system could be seen running through a large opening in the base of the smokestack.

Now all is silent and, after years of sitting idle, this once proud heating and power plant will be demolished in 2014 to make way for future of learning at Purdue, the Active Learning Center.

Sustainable Laboratories

Sustainable Laboratories

Darryl Beals and I recently attended the 2013 I²SL (International Institute for Sustainable Laboratories) conference (formerly Labs 21 conference) in Minneapolis, MN. It was a pleasure being back in Minneapolis where I went to college at the University of Minnesota. The weather was perfect in the high 70s and I had a chance to catch up with some old friends in the evenings after attending seminars all day.

As you can imagine with a conference focused on lab sustainability, much of the 3-1/2 days of seminars and workshops was focused on saving energy in laboratories. As much as 2/3 of the energy usage of a typical research campus is from the laboratory space that is typically less than 1/5 of the buildings on campus. There is a lot that can be done to improve energy efficiency in new and existing laboratories, but one area that is of special interest to me is to reduce airflow. Electricity is our highest cost driver these days, with natural gas prices being historically low across the country. As most engineers are aware from the fan laws any reduction of airflow amounts to a reduction in fan energy to the third power. For instance, a 25% reduction in CFM will reduce fan power usage by 58%. This is savings you can get excited about!

One big opportunity for savings in airflow is in the laboratories themselves. The first step to reducing air flow is to have a lab with Variable Air Volume (VAV) controls to allow varying the flow of air to and from the lab based on the cooling loads and fume hood sash position while maintaining safe minimum airflow during occupied and unoccupied times. With a VAV system and by sizing equipment for the actual expected loads in the space and establishing minimum Air Change Per Hour (ACPH) based on science, airflow can often be greatly reduced. Many times engineers use a minimum ACPH in the lab, such as ACPH of 6, based on a rule of thumb rather than informed understanding of the work actually being done in the lab. Ideally the facility owner would consult with an Industrial Hygienist to determine safe minimum ACPH during occupied and unoccupied times. At the conference, the University of California (UC) – Irvine presented the success they have had reviewing lab air changes with their Industrial Hygienist to reduce ACPH in 85% of 1,610 lab rooms. Often times this reduction in airflow is in conjunction with an air contaminant monitoring system that will increase airflows in the event of a chemical spill or other accident.

Some of speakers at the conference focused on how further reductions in airflow can be made by reducing the minimum exhaust from fume hoods. Assuming you have a variable flow fume hood, the minimum exhaust when the sash is closed is determined by the AIHA/ANSI Z9.5 standard. The latest version (2012) of this standard allows a minimum range from 150 ACPH to 375 ACPH. This equates to about 10 CFM/SF to 25 CFM/SF of fume hood bench top surface with a typical hood. The old ANSI Z9.5 standard required 25 CFM/SF minimum. The new standard allows significantly lower minimum exhaust air flow in less hazardous fume hoods. The facility’s Environmental Health and Safety personnel or Industrial Hygienist should be consulted to establish the correct minimum fume hood flow. Where many fume hoods are in a lab, this minimum flow can have significant affect on unoccupied and even occupied minimum supply air flow.

Reducing airflow is one area of “low hanging fruit” where lab energy efficiency can be greatly improved. If you have a facility that is currently running with a constant volume lab, you could experience significant energy savings by converting to variable volume and making the above improvements. Sometimes budget gets in the way of full implementation of variable flow in existing laboratories. In those cases, you can take a step-by-step approach as we are doing at Purdue Wetherill Laboratory of Chemistry. In this case, exhaust fans have been prepared for variable flow operation and await future phases to implement variable flow within each lab. As explained at the I²SL conference, these improvements, along with some other items, allowed UC Irvine to save 50% or more in energy costs in their labs.
