The customer

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In 2020, the building underwent an extensive renovation, transforming from a vacant and outdated office building into luxury apartments.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. 

The challenge

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.  

The solution

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.  

Lower costs, higher reliability 

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.   

A multipurpose solution 

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. 

Reducing and reusing resources 

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. 

Repurposing space for tenant needs 

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.

The customer

Within a renovated 19th century stable in the Crossroads Art District of Kansas City is Lifted Spirits, a unique craft distillery and event space. Upstairs in their “Hayloft,” where horse feed and bedding were once stored, is a beautiful event space that customers can rent out to enjoy delicious spirits while making lasting memories. This former stable was constructed in the 1890s and converted into a high-end craft distillery in 2016. Ever since, Lifted Spirits has been a staple of the Kansas City community, featuring local artists’ work and hosting seasonal events. The distillery has even been recognized with awards from leading industry organizations, including the New York International Spirits Competition, International Spirits Competition, and American Distilling Institute.   

The challenge 

Lifted Spirits previously relied on a single onsite gas boiler to meet its energy needs. However, after a few years of navigating the complexities, repairs, and maintenance required to upkeep this aging equipment, the new owners sought an energy alternative. The challenge was finding an energy source that would reliably, cost-effectively, and sustainably supply proper control of heat and an abundance of hot water for the distilling process. 

The solution 

After evaluating the lifecycle costs of several energy options, Lifted Spirits’ owners decided that district energy was the optimal solution for meeting their heat and hot water needs, while also achieving significant energy savings. 

Reliable service for a precise distillation process 

Because the distillation process requires precise control for a significant amount of steam, a reliable and high-quality thermal energy source was crucial. Lifted Spirits chose Vicinity in part due to the 99.999% reliability rate associated with its resilient district energy system. 

High-quality food-grade steam 

In Kansas City, the district steam system generates food-grade steam, or culinary steam, to serve manufacturing and industrial customers who use steam in the production of food-related products. Culinary steam is necessary for the distillation process to ensure that Lifted Spirits continues to produce high-quality beverages. Providing a consistent, high-quality product is critical to Lifted Spirits’ overall business and brand reputation, helping drive customer loyalty.  

Achieving cost-savings 

After considering alternative boiler options and comparing the costs and efficiencies of each, Lifted Spirits chose Vicinity’s district energy system to achieve more competitive energy pricing and eliminate labor costs associated with boiler operations. Through a simple connection to the Kansas City district system funded by Vicinity, the distillery now enjoys cost effective thermal energy with minimal upfront capital costs. 

Freeing up mechanical space for business operations 

Without Lifted Spirits’ onsite gas boiler, the owners are able to leverage the added interior space for core business operations. Because the distillery hosts tours, tastings, and custom events, every square foot of space is valuable to enhance Lifted Spirits’ business operations and customers’ experiences.

Heating reimagined: industrial-scale heat pumps for building decarbonization

Revolutionizing the way we heat buildings by integrating industrial-scale heat pumps to produce carbon-free eSteam™

Industrial-scale heat pumps are revolutionizing the energy industry. With the ability to produce temperatures of up to 150C, these powerful systems have become a sustainable solution across the globe. As the demand for carbon-free heating increases, the shift away from fossil fuels is finally gaining momentum.

Vicinity is transforming district energy with plans to install an industrial-scale heat complex. This innovative heat pump complex will draw heat from nearby water sources to generate steam and improve the system’s efficiency. Ensuring that the river and its ecosystems remain unharmed, the river intake system lifts heat from the river and brings it into our facilities.

Key facts

  • The proposed Cambridge heat pump will have a steam export capacity of 35MW (thermal)
  • The heat pump will occupy a space of approximately 25,000 sq ft. +/-
  • The heat pump will circulate through 24.5 million to 49 million gallons of water from the Charles River daily

How heat pumps work

  1. The heat pump compressor, powered by electricity from renewable resources compresses natural refrigerant to pressures upwards of 1,000 psig.
  2. The heated refrigerant is conducted to a heat exchanger for low-pressure steam generation.
  3. The low-pressure steam is transferred to a multi-stage steam compressor, which increases
    steam pressure from 5 psig to 220 psig, the required pressure for distribution into the district energy system.
  4. After generating steam, the refrigerant is routed to a feedwater pre-heating heat exchanger and is condensed.
  5. The liquified refrigerant is then expanded through an expansion valving arrangement. The expansion reduces the refrigerant pressure, gasifies the refrigerant, and sharply reduces the refrigerant temperature to less than 30 degrees Fahrenheit.
  6. The cold, gaseous refrigerant is conducted to a river water heat exchanger to collect energy from the river water. The river water heat exchanger heats the gaseous refrigerant several degrees Fahrenheit while cooling the river water several degrees Fahrenheit. The cooled, gaseous refrigerant is conducted back to the heat pump compressor for reuse in the heat pump cycle.
 

How Vicinity is using heat pumps

Industrial-scale heat pumps will be installed in cities around the country where Vicinity’s facilities are located near water sources and already employ water intake systems. These heat pumps will extract heat from adjacent water sources, like the Charles and Schuylkill Rivers, to generate steam and improve the system’s overall efficiency.

Across all of our operations, heat pumps will be used with electric boilers and thermal storage technologies to fully decarbonize our operations.

This first planned heat pump complex in Cambridge will be powered by renewable electricity to efficiently harvest energy from the Charles River and return the water to a lower temperature.

Early design of the industrial-scale heat pump Vicinity Energy is developing in partnership with MAN Energy Solutions.

Why industrial heat pumps are important for Vicinity, our customers, and the environment

The global energy transition can only succeed with decarbonizing heat. Why? Heating in buildings is responsible for four gigatons (Gt) of CO2 emissions annually—10% of global emissions, according to the International Energy Agency (IEA). The heating sector accounts for 30-40% of CO2 emissions globally.

Water-source heat pumps are a proven solution to fossil- fuel-driven heating because they can efficiently harness the renewable power of water sources.

In 2021, approximately 10% percent of the global demand for space heating was satisfied by heat pumps. In some countries such as Norway, Sweden, and Finland, heat pumps are the most widely used heating source and have already begun integrating with district energy systems. The district system in Glasgow will leverage heat pumps to extract cold water from the adjacent River Clyde. This will cover over 80% of building heat demand and will deliver immediate carbon reductions of 50%.

By installing industrial-scale heat pumps at our central facilities, Vicinity is one step closer to instantly decarbonizing millions of square feet of building space for the good of our customers, communities, and the cities we operate. The impact of this plan is substantial: by 2035, Vicinity’s investments at our Kendall, MA facility will reduce the carbon intensity of our steam by 50%, the equivalent of 400,000 tons.

Steam trap inspections

Maximize steam efficiency, safety, and cost savings with preventative maintenance

Improve the efficiency and safety of steam systems with steam trap inspections by Vicinity’s qualified technicians. Our team will diagnose and identify issues to keep steam systems operating safely and efficiently 24/7.

Steam traps are critical components of steam systems and play a vital role in maintaining their efficiency and safety. Steam traps collect condensate to prevent corrosion caused by built-up moisture and ensure high-quality, dry steam flows through the steam system. Steam traps also block the escape of live steam, minimizing energy waste. Regular maintenance and monitoring are essential to ensure they function correctly and prevent issues that can lead to energy waste, equipment damage, and safety hazards.

Vicinity’s steam trap inspections offer the following benefits:

  • Reduced energy costs: Steam traps in good condition help conserve steam, reducing energy consumption and operational costs.
  • Improved equipment reliability: Properly maintained traps extend the lifespan of steam-related equipment.
  • Enhanced safety: Reducing energy waste and water hammer incidents improves workplace safety.
  • Environmental benefits: Energy conservation through steam trap maintenance can reduce greenhouse gas emissions.

How it works

Partnering with our customers, Vicinity tailors each approach specifically to the unique needs of the building. The process of performing steam trap inspections typically includes the following steps:

  • Vicinity coordinates an initial walkthrough of the building and provides a quote showing the cost and scope of work.
  • Once the customer returns a signed quote, Vicinity’s account manager schedules the work.
  • A Vicinity technician conducts the steam trap inspection using an ultrasonic digital detector. If this is the first survey, the technician tags and catalogs each trap for future surveys.
  • After the inspection, the customer receives a report detailing:
    • The status of each trap.
    • Recommended action items and the potential savings associated with recommended action items.

Efficiency and system performance

When steam traps fail and steam escapes, systems demand more steam to operate. Steam trap inspections improve the overall operating performance of steam systems, minimizing the amount of energy waste and the associated carbon emissions.

Cost savings

Leaking steam traps result in significant lost capital over the life of the equipment. Analysis by the U.S. Department of Energy and the Boiler Efficiency Institute shows that repairing a faulty steam trap could save thousands of dollars annually. Steam trap inspections represent an opportunity for customers to reduce energy consumption and operating costs.

Safety considerations

Safety is our primary focus. With Vicinity’s trained technicians conducting the inspections, customers can rest assured that the proper measures are in place to safely conduct and identify any steam trap hazards that can lead to a water hammer event. A water hammer event occurs when a failed steam trap allows condensate to build in the steam main. As steam passes over and combines with the excess condensate, it creates a pressure event that can lead to undesirable noise, damaged equipment, and—in worst cases—injury.
