Preparing chilled water and cooling equipment for the summer

In the fall, looming cold temperatures and potential storms signal the need for preventative maintenance activities at Vicinity’s central facilities and customers’ buildings. However, as we approach summer’s warmer temperatures, preventative maintenance is just as important.

During the winter months, certain equipment often lies dormant, making it imperative to assess components of chilled water systems and other cooling equipment well in advance of heightened cooling demands. While some property owners diligently prepare their equipment for the impending heat, it is a timely reminder to consult with your energy provider regarding recommended preventive maintenance for the summer season, whether you rely on district chilled water or steam for cooling or manage your onsite chillers and cooling towers.

Why summer preventive maintenance is critical

As spring begins, it presents an opportunity to inspect cooling equipment that lay dormant throughout the heating season. Implementing preventive measures before the onset of summer and escalating temperatures can yield numerous benefits:

  • Improve equipment reliability, function, and overall lifespan
  • Reduce energy consumption, greenhouse gas emissions, and operational costs
  • Prevent unplanned costs and even system downtime
  • Enhance safety and comfort for employees and building occupants
  • Maintain efficient energy delivery
  • Ensure the long-term sustainability of a property

How to prepare cooling equipment for warm weather

Partnering with our customers, Vicinity’s team tailors our preventive maintenance approach to the unique needs of each building. Preventive maintenance activities can be done at any time but are typically conducted in preparation for the winter and the summer to prepare for peak loads due to temperature changes.

Whether customers need support with recommissioning an onsite cooling system or performing seasonal shutdowns to prepare steam systems for the summer, Vicinity’s operations and maintenance experts can help ensure the equipment will operate effectively for the coming summer and the next heating season. Depending on the building’s system, our team can isolate a maintenance issue or conduct a small shutdown event to repair equipment. Ahead of summer temperatures, Vicinity’s team can test a building’s chilled water or steam system during off hours or weekends to identify any problems.

Several elements of cooling systems require inspection every year or more. Let’s dive into the most critical components buildings should focus on when preparing for the cooling season.

Heat exchanger and water samples

A heat exchanger is a system that transfers heat between a source and a working fluid. In the winter, district energy systems transfer heat from the hot water in the district heating system to the cold water in an individual building’s heating system. In the summer, district chilled water customers rely on this equipment to leverage Vicinity’s chilled water to circulate cool air throughout their buildings.

To ensure that heat exchangers function properly, Vicinity’s team takes water samples from the heat exchanger and tests the water for conductivity. This test helps ensure that tube bundles are not leaking and that city water is not entering the system through such leaks. It’s also important to make sure these systems are clean and are not experiencing any leaks.

Pressure Regulating Valves (PRVs)

Pressure regulating valves (PRVs) are designed to reduce incoming steam pressure to ensure safe steam distribution. Vicinity’s team identifies the PRV’s make, model, size, and serial number. They will then test the valve for leaks, clean orifices, check diaphragm plates, test the gauging, and set it to the desired system pressure.

Testing PRVs is important because failed PRVs may cause system over-pressurization and relief values to release steam into the atmosphere. If a PRV fails, it can also improperly cycle open and closed, oversupplying and then starving the downstream equipment of steam. Testing includes inspecting the PRV operating mechanism (pneumatic, hydraulic, or motor-operated). Whether a building turns off steam for summer or leverages steam for cooling purposes, PRV testing is critical for overall system efficiency and reducing any potential energy losses.

Mechanical room hot water loop

In a building’s mechanical room, Vicinity’s team inspects all piping, inlet/outlet temperatures, and pressures on heat exchangers and mechanical pumps.

This inspection confirms the adequate operation of key energy transfer equipment, such as heat exchangers, which supply building heat, hot water, and other process loads. It is also important to note the general condition and function testing of space heaters and heat tracing.

Cooling towers and chillers

Chillers and cooling towers are important components of some buildings’ cooling systems. While chillers cool down water using a refrigerant, which is then circulated through the building to absorb heat from the air, cooling towers then reject heat from the chillers’ condenser water and return it to the condenser at a lower temperature as part of the system’s refrigeration cycle.

Vicinity can partner with customers who do not leverage district chilled water and own onsite cooling towers and chillers, providing additional operation and maintenance support to ensure a seamless transition to summer.

Cooling tower maintenance activities for customers who own and operate onsite equipment include disinfecting equipment ahead of seasonal startup to prevent the growth of harmful bacteria; replacing oil in gearboxes to prevent friction and corrosion; performing vibration analysis to mitigate risks related to increased noise, safety concerns, and system inefficiencies; inspecting and repairing distribution spray pipes and nozzles; cleaning basins; and upgrading fan blades and drive shafts as needed.

Chiller maintenance includes removing any dirt or debris collected throughout the year to optimize airflow; checking levels of refrigerant and assessing if additional refrigerant should be added; inspecting all chiller and condenser pumps; cleaning and servicing all variable frequency drives (VFDs) and glycol heat exchangers, the equipment used to cool VFDs; taking oil samples and adjusting levels; and cleaning condenser tubes to maximize equipment lifespan and improve overall energy efficiency.

Summer preparedness checklist

Vicinity’s facilities, especially those with chilled water, take extensive measures to prepare for summer temperatures before the beginning of April. This ensures that our facilities and teams are prepared for any weather or heat-related emergency.

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 by installing 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

  • Our 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 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.

How district energy is helping commercial buildings meet Boston’s BERDO 2.0 requirements

Like many cities nationwide, Boston has set aggressive climate goals to curb the harmful effects of climate change. Boston aims to be carbon-neutral by 2050, meaning the City will only be able to release as much carbon as the environment can safely absorb.

But how does the City plan to make this happen?

In large part, carbon neutrality will come from decarbonizing the energy-intensive buildings that operate in Boston: commercial offices, hospitals, colleges and universities, and many others.

The Building Emissions Reductions and Disclosure Ordinance (BERDO), originally enacted in 2013, required large Boston buildings to report and disclose their emissions.

In 2021, however, the amended ordinance — BERDO 2.0 — was unanimously passed by the Boston City Council and signed into law, officially moving the ordinance beyond reporting and setting enforceable emissions standards for buildings. In 2023, BERDO 2.0 policies and procedures were finalized.

Crucially, the ordinance aims to eliminate the 70% of greenhouse gas emissions that commercial buildings contribute to the City of Boston.

What BERDO 2.0 means for Boston building owners and developers

The 2021 amendment to BERDO gives the City of Boston authority to set emissions standards for large existing buildings. The emissions thresholds will decrease to reach net zero by 2050.

BERDO 2.0 states enforceable minimum building emissions performance standards, measured in kilograms of carbon dioxide equivalent per square foot per year. These emissions standards differ by building use but will begin to apply in 2025 for already-covered buildings and in 2030 for newly-covered buildings. Based on 2022 emissions reporting, several hundred buildings in Boston are projected to exceed their emissions limit in 2025.

BERDO 2.0 also imposes changes in enforcement penalties. The amended ordinance introduced fines for failing to meet the performance standard and inaccurate reporting.

BERDO 2.0 does not just apply to commercial buildings, but also applies to the following:

  • Non-residential buildings that are 20,000 square feet or larger.
  • Residential buildings that have 15 or more units.
  • Any parcel with multiple buildings that sum to at least 20,000 square feet or 15 units.

In addition, the amended ordinance proposes potential ways buildings can achieve their required emissions reductions, including on-site energy efficiency or renewable energy measures, fuel switching, and clean electricity purchasing options like Renewable Energy Portfolio Standard (RPS) Class I eligible Renewable Energy Certificates (RECs) generated by non-CO2e emitting sources, and Power Purchase Agreements (PPAs) with non-CO2e emitting renewable sources.

To find out whether they are over the emissions limit and get an estimated emission reduction forecast, buildings can use the City of Boston’s BERDO emissions calculator. 

How district energy meets BERDO 2.0 requirements

Our team of experts at Vicinity is prepared to help building owners and developers in Boston meet the aggressive emissions reduction requirements posed by BERDO 2.0 and avoid paying alternative compliance payments.

Our clean energy future plan outlines our roadmap to reaching net zero carbon emissions across all our operations by 2050 or sooner. Central to our decarbonization plan is the innovative eSteam™ product.

To generate eSteam™, Vicinity will import carbon-free electrons through co-located substations to power electric boilers, coupled with industrial-scale heat pumps and thermal batteries, to deliver electrified, carbon-free steam, known as eSteam™, for heating, cooling, sterilization, humidification, and other thermal energy needs.

Building upon success stories in European countries like Norway, Finland, and Sweden, Vicinity is electrifying our district energy systems. Our approach is based on our ability to:

  • Leverage established technologies such as industrial-scale electric boilers and heat pumps to convert electricity into steam;
  • ​Capitalize on the flexibility of our existing assets that connect to the electric transmission system today​;
  • Take advantage of the future economics of renewable electricity to introduce green electrons to our fuel mix;
  • And utilize the agility of fuel-agnostic district energy to decarbonize, easily “flipping the switch” to greener fuels​.

By electrifying our central facilities, all our customers can access carbon-free eSteam™ to meet building performance standards and avoid costly building modifications.

Our team is actively working towards our goal of net zero. In November 2022, we kicked off our electrification plans by deconstructing a steam turbine at our Kendall facility. We are installing an electric boiler in its place, which will enter service in 2024.

In April 2023, we took another crucial step in our clean energy future plans by announcing our partnership with MAN Energy Solutions to develop low-temperature source heat pump systems for steam generation. Currently, we are designing the heat pump complex, which will occupy a space of approximately 25,000 sq. ft. and will circulate through 24.5 million to 49 million gallons of water from the Charles River each day, returning the water to the river at a lower temperature and ensuring that the river and its ecosystems remain unharmed.

Meeting BERDO 2.0 requirements with eSteam™

eSteam™ is carbon-free and recognized in the BERDO 2.0 regulations. This thermal product offers a straightforward solution for commercial landlords and developers trying to meet the ordinance’s carbon-reduction goals.

Vicinity’s eSteam™ is recognized as emissions-free by BERDO 2.0 regulations, providing customers with a compliant and cost-effective solution.

The Vicinity team assists customers in Boston with BERDO 2.0 reporting energy usage through Energy Star Portfolio Manager, one of the three reporting requirements set by BERDO 2.0.

Our team sends energy usage data and an annual energy summary to customers every month, making their reporting process more efficient and accurate.

Carbon reduction acts in Boston and beyond

While Boston is undoubtedly leading the country by reimagining the energy industry, many other cities around the U.S. are planning to enact ordinances similar to BERDO 2.0.

The City of Baltimore, for example, is currently in the implementation stages of the Climate Solutions Now Act, or SB 528. The act proposes a greenhouse gas reduction goal of 60% by 2031, with net zero carbon emissions by 2045.

Vicinity’s district energy systems are uniquely poised to help building owners and developers in Boston, Cambridge, Baltimore, Philadelphia, and more to meet building performance standards today and in the future.


Market update: natural gas outlook winter 2024

As we continue into the winter season, Vicinity’s team has been evaluating weather patterns and predictions for the natural gas market to prepare our customers for potential price fluctuations.

After peaking in December 2023, the El Niño pattern continues, and February 2024 weather forecasts indicate above-average temperatures in the Northeast and Midwest, induced cooling in the South, and higher precipitation in the Pacific, which experts predict may continue into the remainder of the winter season.

The natural gas markets have reset to similar levels as 2021, before the geopolitical events in 2022 drove prices above average.

By the numbers: what we know and what we can expect

Prior to January 2024’s well freeze-offs, the U.S. lower 48 saw strong natural gas production, primarily due to efficiencies in the Permian Basin of the U.S. that have provided ample supply to the market, mitigating demand risk. However, due to colder weather in the Permian basin in recent weeks, natural gas production has fallen.

Currently, natural gas storage levels are 4% above 2023 levels and 5% above the 5-year average. Europe’s storage facilities were 80% full through the first half of January 2024, slowing European demand for LNG and suppressing pricing.

Colder weather conditions in January 2024 have contributed to well freeze-offs in the Permian natural gas basin, impacting output and potentially providing more upside risk to pricing. However, the January 2024 futures contract settlement was less than levels at this time last year.

Key electrification progress

The adverse effects of natural gas far outweigh the benefits of continuing to invest in this unsustainable fuel source.

In 2023, the U.S. saw an estimated 1.9% decrease in carbon emissions, as measured in research done by the Rhodium Group. Throughout the year, emissions remained below pre-pandemic levels and dropped to 17.2% below 2005 levels.

While this decrease is substantial, an even greater emissions reduction is necessary to limit climate change. In 2023, Earth’s average land and ocean surface temperature was 2.12 degrees F above the 20th century, making it the highest global temperature among all years recorded since 1850, according to the U.S. National Oceanic and Atmospheric Administration.

The undeniable climate crisis drives Vicinity’s progress towards transitioning away from fossil fuels and eliminating carbon emissions from our operations. By electrifying our operations nationwide, we will be able to offer an affordable, carbon-free path for building owners to meet sustainability goals and join us in limiting climate change.

Our first electric boiler has been delivered to our Kendall facility in Cambridge, Massachusetts, and it will enter service in 2024, immediately allowing our customers to harness carbon-free energy and decarbonize their buildings.

The industrial-scale heat pump complex we are developing in partnership with MAN Energy Solutions is undergoing engineering and will enter service in 2026. These milestones demonstrate our commitment and progress towards a net zero carbon future.
