Weber State College is creating an environmentally pleasant, energy-conscious campus that concurrently serves as a dwelling laboratory for college kids in its engineering and environmental packages. The college’s environmental targets embrace electrification by eliminating standard, pure gas-fired, and fewer environment friendly HVAC techniques. Up to now, about half of the campus’ HVAC techniques are totally electrical.

Traditionally, Weber State College’s buildings have been cooled with chilled water from a central water plant and heated with steam from a central steam plant, neither of that are energy-efficient in comparison with trendy techniques. As we speak, a lot of its buildings have been retrofitted with all-electric, all-climate, water-source warmth pump options. Transferring ahead, the college plans to transform the whole campus to Mitsubishi Electrical Hybrid Variable Refrigerant Stream (VRF) options. Hybrid VRF techniques use water as an alternative of refrigerant indoors and are a key know-how within the motion to affect and decarbonize buildings.

“We’re additionally creating an power restoration community for our complete campus, with all buildings linked to the identical water loop,” mentioned Justin Owen, Interim Director of Operations for Weber State College.

“The Mitsubishi Electrical warmth pumps linked to that water loop allow us to save cash on our electrical energy payments and reinvest these financial savings into renewable options like photo voltaic, which permits us to supply that electrical energy renewably,” he mentioned.

Studying About All-Local weather Warmth Pumps

In 2015, Weber State College began putting in water-source VRF techniques. As an illustration, the college has a ductless, water-source VRF warmth pump system from Mitsubishi Electrical in its Noorda Engineering constructing. The Noorda Engineering constructing is dwelling to the college’s electrical engineering, mechanical engineering, and power engineering packages. Most elements of the VRF answer are on show to college students, labeled and uncovered – from the condenser to the department controller to the fan coils – enabling them to study and work with all-climate warmth pump know-how.

College personnel attending a commerce present in Las Vegas have been launched to the Mitsubishi Electrical Hybrid VRF answer by their HVAC distributor, Utilized Product Options, positioned in south Salt Lake Metropolis. In 2024, Weber State put in its first water-source, Hybrid VRF answer in its six-level SkySuites, an addition to Stewart Stadium. The SkySuites home the Weber State Athletics Division, teaching employees places of work, a press field, 26 suites, 150 membership seats, and a research space for student-athletes.

“One factor that I’ve been actually impressed with concerning the Mitsubishi Electrical hybrid system is that it makes use of much less refrigerant than a extra standard system, which is absolutely vital to us, particularly with the approaching modifications to new low GWP refrigerants,” mentioned Brad Lash, P.E., Vice President, WHW Engineering.

Having fun with the Advantages of VRF and Hybrid VRF

A bonus of VRF and Hybrid VRF know-how is improved consolation and effectivity offered by zoning. With zoning, every room has its personal thermostat, giving occupants management to warmth or cool their house to their consolation degree.

“At our homecoming soccer sport, I finished by our presidential suite as a result of traditionally, the SkySuites’ temperature was laborious to handle, mentioned Owen. “When i requested President Martinson in regards to the temperature, he mentioned, ‘It’s been nice. It’s usually sizzling in right here, however I’m comfy.’”

Weber State College additionally advantages from Mitsubishi Electrical good power controllers that include a light-level sensor and an occupancy sensor. These energy-saving options allow employees to remotely management temperatures and modify thermostats in unoccupied rooms to avoid wasting on power payments.

“Mitsubishi Electrical Hybrid VRF consumes quite a bit much less power than our standard techniques,” mentioned Owen. “At any time when we do a retrofit, I run some power numbers on what we consumed earlier than and what we devour now. Mitsubishi Electrical techniques permit us to lower our power footprint by about 70% to 80%.”

Plus, VRF and Hybrid VRF options are straightforward to carry out routine upkeep on, in response to Sean Dorsey, Service Advisor, Utilized Product Options. Weber State selected to make use of largely four-way ceiling cassettes within the SkySuites as a result of these indoor models have simply detachable air filters on the ceiling degree.

“We offer a whole set of filters for each indoor unit,” Dorsey mentioned. “Once they do upkeep, they take out the filter, place a brand new one, and wash the soiled ones so that they’re prepared for the subsequent time.”

Making a New Commonplace

Hybrid VRF options are excellent for retrofit initiatives like Weber State College’s conversion from standard HVAC techniques to extra trendy know-how. The Mitsubishi Electrical ductless Hybrid VRF answer set up within the SkySuites took simply eight months from begin to end. One other good thing about a ductless system was that it was simpler to run piping as an alternative of ducts by means of the SkySuites’ tight ceiling house.

Since Weber State College is dedicated to achieve carbon neutrality by 2040 and cut back the environmental impression of all operations, Mitsubishi Electrical Hybrid VRF options allow the campus to satisfy its energy-conscious targets. In reality, its sustainability initiatives are a number one instance for different universities prioritizing decreasing their carbon footprint.

“Hybrid VRF is now our normal,” Owen mentioned. “We’ve got three initiatives in design proper now that may also be Hybrid VRF, and our plan is to transform the remainder of the campus to hybrid.” Owen acknowledged that the constructive environmental impression, lowered power price, and the general lifecycle price of the techniques have impressed him.

In reality, he mentioned Weber State College is bought on the Mitsubishi Electrical model solely due to the corporate’s high-performing all-climate warmth pump merchandise, performance, power restoration, easy-to-use thermostats, intuitive management techniques, native HVAC assist, and warranties.
