Project Profile: Dodge City Schools

Exterior (3)_web

“I can hear my teacher now.” That was one student’s reaction in Dodge City, Kansas, after the school district began renovating each of its 10 schools’ HVAC systems. When it paired our Water-source Variable Refrigerant Flow (VRF) with geothermal technology in two of its buildings, that same wonderful thing happened – suddenly, students could hear their teachers. Additionally, the district saw reduced utility bills, green certification and satisfied teachers.

Each summer now, the district focuses efforts on one renovation. Our water-source VRF technology entered the scene during the second summer as part of improving conditions in the 35,000-square-foot Central Elementary School (Central) – a two-story brick facility built in 1927. Water-source VRF paired with geothermal technology replaced outdated, inefficient HVAC systems. VRF brought efficiency, true zoning and excellent control to that pairing.

The following summer, Wilroads Elementary School (Wilroads) – a 19,000-square-foot building from the 1950s – was renovated by pairing our water-source VRF systems with geothermal technology. Drew Rose, electrical engineer, Integrated Consulting Engineers, Inc., Wichita, Kansas, has served as the project manager and designer for the ongoing Dodge City Schools projects. Rose said of the Wilroads installation that “everyone’s been satisfied since, and the teachers were really excited to get something that works without being loud.”

Both Central and Wilroads also earned ENERGY STAR® certification; Central even got a score of 91! “When you think about how it was built in 1927, well, we think that’s pretty impressive,” said William Hammond, the district’s executive director of business operations.

The Dodge City Unified School District’s energy manager, Morris Reeves, spoke of the decision to use VRF: “We work every day to conserve energy. Energy conserved is more money for the classroom – that’s what we’re all about.” Hammond added: “I like being green to save energy and resources, and being green to save money. I try to find projects that do both.” By pairing our water-source VRF systems with geothermal technology, the school district was able to do both. This pairing even earned the district a claim of $215,000 in grants and rebates. And now, nearly 7,000 students can hear their teachers.

Waste Water Technology Opens New Avenues of Energy Recovery

Jan 13 Image

Water-source Variable Refrigerant Flow (VRF) systems are one of the most energy-efficient ways to cool and heat a building.  Water sourcing helps maintain a consistent temperature without having to constantly monitor and maintain air temperature, and VRF’s small piping makes installation and renovation simple. However, water-based systems can be a challenging application in areas like California, where water conservation is a daily concern.

In the District of Columbia, D.C. Water has developed technology to convert waste water into energy by converting solid byproducts into usable energy, while also funneling steam back into the energy recovery process. D.C. Mayor Muriel Bowser said, “D.C. Water’s Blue Plains facility is converting waste to clean water and a nutrient-rich soil byproduct, producing energy and helping to put the district on the path towards a zero waste future.”

We’re excited to watch this technology spread across the country. Applying it in water-conscious areas makes water source VRF a more viable option. As we all look for ways to operate more efficiently and thoughtfully, this is potentially very good news.

An Important Achievement in Efficiency

We’re excited to add L-Generation water source condensing systems to the CITY MULTI® family. The next-generation W-Series systems combine the efficiency of water source with VRF, offering enhanced efficiency ratings across all categories. Further efficiency can be achieved by integrating these systems into specialized water-side designs like geothermal or existing closed water loops, and by recovering heat on both the refrigerant and water sides of the system. In a marketplace where efficiency matters more every day, L-Generation technology represents an important achievement.

The features and benefits of our W-Series systems go far beyond efficiency, however. They include:

  • Single modules up to 20 tons, with the ability to combine single modules for systems up to 30 tons
  • Easy installation indoors
  • Convenient front-side service access
  • Ability to stack multiple systems, creating more horizontal space and storage
  • Self-cooling cabinet
  • Ability to connect multiple systems to a central controller, giving owners and managers total operational and comfort control
  • Extended 10-year parts and compressor warranty available

How Well Do You Know Water-source VRF?

September 2_ HPAC Engineering Webinar Image

Registration for our free, hour-long webinar, “A New Era of Efficiency: Advances in Water-source VRF Technology,” is now open!

Variable Refrigerant Flow (VRF) technology has become a $500 million segment of the market in just over a decade. On September 15, we are joining forces with HPAC Engineering magazine to discuss one facet of the technology contributing to that growth: water-source VRF. Kevin Miskewicz, senior manager – commercial marketing, and Charlie Landherr, regional manager, commercial, will discuss the recent technological developments that have ushered in a new era of efficiency.

Attendees will learn:

  • How the demand for higher energy efficiency has guided HVAC manufacturers.
  • How water and air source VRF differ, and the various features and benefits of each.
  • Why so many engineers use water source VRF to learn LEED® points.
  • How VRF can be paired with a geothermal, or other closed loop, system.

Have You Checked Out Our Latest White Papers?

white papers

We developed two new white papers to educate architects, builders, contractors and engineers on one of the HVAC industry’s most compelling markets.

Our Multifamily White Paper describes the major benefits of Variable Refrigerant Flow (VRF) zoning systems, how they meet the demands of designing and building multifamily housing and solve HVAC-related challenges specific to these types of constructions. The Geothermal White Paper provides readers with an overview of water-source (geothermal) VRF zoning technology, its advantages compared to conventional systems and best practices and considerations for selection. Both white papers feature real-life case studies of successful applications.
