Awarded the 2024 Tripadvisor Travelers’ Choice Award, the Kansas City Marriott Downtown offers premium guest experiences and business events with onsite restaurants and bars, multifunctional meeting spaces, a fitness center and pool, and access to downtown destinations. The hotel consists of two buildings: the Marriott main tower, 450,000 square feet of space, and the historic Muehlebach Hotel, 291,000 square feet of space. With a rich history dating back to 1914, the Muehlebach hosted American icons, including Babe Ruth, Helen Keller, Frank Sinatra, and former presidents. Most notably, it was the site where President Truman signed legislation as part of his post-war Truman Doctrine. Today, the Marriott continues to have a lasting impact on Kansas City’s vibrant downtown.
The Marriott team was recently challenged with its aging onsite chillers and cooling towers, which were at risk of failing and disrupting the hotel’s daily operations. Replacing the 30-year-old equipment would have been a logistically complex and costly endeavor, requiring either craning equipment to the roof or demolishing part of the building’s exterior to install new chillers on the fourth floor. Additionally, the condensing water pumps and associated piping were aging, further escalating the potential cost of upgrades. To avoid this expensive capital project and limit disruptions to the hotel’s ongoing operations, the Marriott team selected Vicinity’s chilled water as the new cooling solution. By choosing district energy, the hotel unlocked capital savings for other critical infrastructure investments, including more efficient chilled water pumps and controls.
For nearly four decades, the Kansas City Marriott Downtown has leveraged steam from Vicinity’s district energy network for heating and domestic hot water to keep guests comfortable in the cold winter months. Steam service is critical for the domestic hot water to instantaneously heat for large volumes of hot water for guests preparing for the day. It also serves the high demand of laundry service hot water to allow the hotel to efficiently turn over rooms with new linens. Additionally, in the hotel’s kitchens, food-grade steam is used in steam kettles and steam tables for food preparation. Expanding its district energy services to include chilled water is yet another way the hotel demonstrates its commitment to uninterrupted, reliable service for its guests. With redundant power and back-up generation, Vicinity helps the hotel provide reliable cooling to the hotel when its guests need it most.
Adding district chilled water represents a pivotal moment in the hotel’s journey toward greater sustainability. In fact, the hotel is making significant strides in reducing its onsite greenhouse gas emissions, avoiding an estimated 9 million pounds of carbon emissions by leveraging district energy rather than relying on onsite equipment powered by the electric grid. As Vicinity progresses its nationwide decarbonization strategy and integrates state-of-the-art technology to electrify its central facilities, the hotel will have the opportunity to further reduce its carbon footprint and impact on the planet. The Kansas City Marriott Downtown serves as a model for how buildings can balance historic preservation with modern energy solutions by leveraging district energy.

Opening its doors to guests in 1931, Hotel Phillips is an iconic Art Deco building located in the heart of downtown Kansas City. With 217 rooms, the 20-story landmark was listed on the National Register of Historic Places in 1979. Many of the original details remain today, including the walnut paneling, intricate metalwork, a 20-story mail chute, Art Deco lighting fixtures, a speakeasy, and a gilded statue of the goddess Dawn. The hotel’s historic character, state-of-the-art amenities, and superior guest services provide a unique experience for all visitors.
Due to the building’s aging infrastructure and need for upgrades—mainly replacing the cooling tower—Hotel Phillips needed a cost-effective solution to provide efficient cooling to keep guests comfortable. The owners considered the complexity of chillers, the associated annual maintenance costs, and the staffing required for safe and efficient operation. Given these concerns, Hotel Phillips wanted to explore cooling options to reduce operational complexity and disruptive downtime.
Since Vicinity already supplied Hotel Phillips with green steam for over two decades, switching to district chilled water rather than purchasing onsite chillers was a seamless and easy decision. To support the hotel in connecting to the chilled water system, Vicinity invested capital in the expansion project, including street repairs, landscaping, and beautification to benefit the surrounding Kansas City community. With Vicinity’s operations and maintenance (O&M) support and dedicated customer service, the hotel now benefits from improved operational efficiency, increased reliability, and expert help on demand.
“We’ve been very happy with our longstanding steam service from Vicinity, and look forward to the additional efficiency, reliability and peace of mind we can expect from their chilled water service. Keeping our guests comfortable is our number one priority and we’re also so proud to be reducing our carbon footprint in the process,” states Hotel Phillips General Manager John Glenn of Arbor Lodging Partners LLC.
The switch to Vicinity’s chilled water substantially reduced the hotel’s upfront capital expenses, associated operations, and maintenance costs. With a lower total cost of ownership than onsite chillers, Hotel Phillips can now repurpose funds and staff hours to core business operations, optimizing guests’ experiences.
Swapping the hotel’s cooling tower with chilled water yields a sizeable reduction in the hotel’s water and energy consumption, resulting in a net environmental benefit to the city. As Vicinity advances its net zero carbon plan across all its operations, Kansas City customers, like Hotel Phillips, will continue to receive greener energy solutions and reduce their carbon footprint. Vicinity’s district energy system in Kansas City plays a pivotal role in creating a sustainable, cleaner future.

Constructed in 1974, the nine-story, 207,000 square foot Executive Plaza building epitomizes the late-modern architectural style. Due to its abstract reflective glass curtain wall, the building became known simply as “Flashcube.” This architecturally significant building earned a spot on the National Register of Historic Places and remains a centerpiece of Kansas City.
In 2020, the building underwent an extensive renovation, transforming from a vacant and outdated office building into luxury apartments. Today, Flashcube is home to 184 apartments and nearly 18,000 square feet of premier co-working office space. Tenants enjoy state-of-the-art amenities, including an indoor soccer field, rock climbing wall, indoor basketball courts, and a resident lounge and game room.
Because Flashcube sat vacant for more than 15 years, the onsite chillers and boilers were prohibitively expensive to resurrect. The plans to convert the building from office space to multi-family residences required a complete demolition of the interior space. This transformation presented many different mechanical system options for the owners to consider. The building owner also needed individual metering at each apartment to empower tenants to control their individual energy consumption and expenses.
With an eye towards innovation, sustainability, and cost control, Flashcube’s owners explored a more reliable and cost-effective heating and cooling system. An extensive third-party analysis compared the lifecycle cost of onsite chillers and boilers, district energy, a water source heat pump system, variable refrigerant system technology, and a residential split system. When accounting for the costs of installation, maintenance, energy, water, and capital replacement cycles, it was determined that district energy provided the best overall lifecycle cost.
By choosing Vicinity’s district energy network, Flashcube’s new owners saw a reduction in construction costs by removing the need for onsite heating and cooling generation equipment, reutilization of existing piping, reduced electrical infrastructure, and tenant metering solutions. While reducing ongoing operating costs, district energy helped boost reliability for tenants.
District energy helps keep Flashcube’s tenants comfortable and safe year-round. Vicinity’s district chilled water connects with simple heat exchangers to tenant fan coils, which eliminates the need for complex, large chillers and cooling towers onsite. District steam is used for building heat, domestic water heating, and a snow melt system, eliminating the need for large onsite boilers and water heaters.
Rather than being discarded as waste, the condensate from the steam generation is used to pre-heat Flashcube’s domestic hot water and is then recycled as grey water to supply the building’s toilets. By recovering the steam condensate to heat the domestic hot water supply and grey water system, this steam biproduct saves money, energy, and city water.
Another advantage of forgoing onsite chillers and boilers is new usable building space. By designing its heating and cooling needs around district energy, the owners of Flashcube have additional room for unique tenant amenities—all while leveraging an energy source that is driving carbon reductions. In fact, the mechanical and backup house space in the basement is now an inviting office space for tenants to access.
