70% of public schools in California are over 25 years old and schools throughout the state are projected to need over $100 billion for facility maintenance and modernization. P2S has been directly addressing this need, working with California school districts to design updated K-12 facilities to better serve students. Mechanical Engineer, Scott Newman has been on the frontline of these efforts, working on several K-12 projects, including comprehensive modernizations, at several different school districts. We spoke to him to learn more about the projects he’s worked on and to take stock of the current K-12 construction landscape. What type of K-12 projects have you been working on recently? Scott Newman: Recently we’ve been focusing on HVAC projects at Long Beach Unified. LBUSD passed a bond a couple of years ago to add air conditioning to all its campuses that didn’t currently have it. Back when they were planning these campuses in the 20’s and 30’s schools just weren’t built with air conditioning systems. Through the years that followed they added HVAC to some of their schools, but rumor has it that the district had a specific boundary that they considered close enough to the coast to not require air conditioning. That’s just not the case anymore with temperatures reaching into the 90s and 100s on an annual basis. We’ve done a number of these projects recently where we design HVAC retrofits for campuses that have never had cooling. Which kinds of HVAC systems are you designing for these campuses? SN: It varies by school. Just like with any project, at the beginning, we take a holistic look at each campus and see what their needs are. Decisions are driven by cost and the capabilities of the facilities and maintenance staff. We’re doing a lot of packaged units and a lot of VRF (Variable Refrigerant Flow) systems. A lot of districts are becoming more comfortable with VRF systems because it gives them increased efficiency and centralizes maintenance since there’s only one condensing unit to work on, instead of having everything spread out over the roof. VRF systems cost more than packaged units, that’s why some school districts can be a bit hesitant. LBUSD was concerned about VRF’s cost and the ability of their staff to work on them but we were able to convince them of the benefits. These benefits include increased efficiency and lower utility costs, which put dollars back in their pockets. When a client is adding cooling at the scale of an entire school district, it’s going to dramatically increase their energy use. Anything we can do to shave off a bit from their annual costs will be much appreciated. That’s part of the service we offer, we talk through that with clients to figure out where their tipping point is for efficiency and where it makes sense to just put packaged units on the room because that’s what makes the most sense. How many LBUSD campuses are you providing HVAC systems for? SN: We’ve done designs for about a dozen campuses so far. LBUSD is splitting up the projects by regions within their district and there’s more coming down the pipeline. Part of our region includes the neighborhoods immediately surrounding the P2S Long Beach office, all the way down to Cal State Long Beach and to the shore. Bixby Elementary, Naples Elementary, Wilson High, Kettering Elementary, Rogers Middle, and Bryant Elementary are some of the schools that we’ve worked on in this region. Can you tell us about a notable K-12 project you’ve worked on? SN: The Wilson High School project is front and center in the region and in the community. I was the Lead Mechanical Engineer on this project, that by name is an HVAC modernization. But we’re also replacing all the lighting, designing new ceilings, adding new telecom and audiovisual systems and doing some electrical infrastructure upgrades. When the District started up the first round of these HVAC modernizations, they quickly realized that in order to get to the result they really wanted, they would need to add in the other parts. Adding ductwork led to the new ceilings, which led to the lighting replacement and so forth. As for the HVAC system itself, we’re doing a combination VRF and Dedicated Outdoor Air System (DOAS) that covers most of the buildings at the school, which is a huge campus. VRF systems make 5
