Four Ways to Maximize Energy Procurement Savings

By Drew Fellon, business leader for energy supply services, Trane

 

It’s well-known that energy costs are always one of the most significant portions of a commercial building budget. Finding ways to reduce that spend can be tricky, but there are ways you can impact it: reduce the amount of energy consumed, change the time of day energy is used, or reduce how much you pay for that energy.

Typically, reducing energy consumption is the go-to solution many building owners and energy managers use in an effort to reduce costs and improve sustainability. While this is an impactful way to decrease energy spend, there’s another, less-conventional strategy, that is often overlooked — even though it can yield significant savings — energy purchasing.

The obvious, though less common, solution is gaining traction in the industry as owners and managers explore ways to reduce their energy spend budgets. Developing a strategy for examining and assessing your energy procurement options can help you make the most of your commercial building budget.  

Consider these energy procurement best practices to help streamline the energy supply process, maximize savings and optimize efficiency in your next commercial building project.

Tip No. 1: Engage a knowledgeable partner

Energy procurement is a complicated process, compounded by the many factors that impact energy rates. Working with a reputable and knowledgeable partner makes the process easier — and can save your company money.

Energy procurement and management companies are powerful resources that can help you avoid spending too much on energy. These companies have long-standing supplier relationships and market intelligence capabilities that they leverage as they work with you through the procurement process and can assist you in getting the best deal possible. Using energy price forecasting, regulatory and legislative monitoring, and years of energy industry experience and contacts, an energy procurement and management firm can help you make insightful decisions to reach your company’s goals.

When choosing to engage an energy procurement and management company, select an experienced partner with insight into the full supply chain and industry pricing structure. This organization can provide visibility to the tens of thousands energy transactions taking place annually. Consider working with an independent advisor without ties to a specific energy company or market. This independence helps create loyalty to you, not the energy supply company, and will provide transparency throughout the procurement process.

The right procurement and management partner can help you navigate the energy purchasing waters — and prepare your company for trends that may impact the industry down the road.

Tip No. 2: Consider your goals

Saving money is typically the top priority for most energy and supply chain managers examining their energy procurement options. But as customers demand more efficient, environmentally conscious solutions for their buildings, many energy and supply chain managers are prioritizing sustainability and the use of renewable energy. When it comes to reaching these types of goals, you need to look beyond price in the purchasing process. It all comes down to what you’re trying to achieve.

If the goal is to reduce energy costs by 10 percent, then purchasing renewable energy is likely not the solution. And if you are hoping to reduce the company’s carbon footprint, you’ll need to buy a certain type of energy that may not always have the lowest price tag. All of which is to say, that putting sustainability first, can look very different than your typical energy procurement process and sources.

Because many energy contracts are long term (between 10 – 20 years), it’s important to take a comprehensive, enterprise-wide approach to buying renewable energy solutions. If your enterprise has buildings or operations in many states, you can achieve more buying power when you coordinate efforts.

Make sure you’re considering the total end cost of an energy contract. There are many factors that affect the final cost of an energy contract, and this may not be clear in every situation. An energy procurement and management firm can help you understand the total cost of the contract structure — not just the initially quoted supply price.

Tip No. 3: Link supply with demand

Before entering into a supply contract, you should fully understand all the factors that influence energy demand in your building — including the supply and demand relationship. Pay close attention to how much energy your building or enterprise uses, taking time to look at both prior and forecasted usage, to determine how much energy to buy.

It is imperative that the supply chain, which drives purchasing, communicates with the operations staff, who oversees day-to-day use of building facilities. Otherwise, the energy manager or supply side personnel may assume that because X amount of energy was used last year, X amount of energy will be needed again next year. When in reality, operations may plan to install a new production line or more energy efficient equipment that will impact the facility’s energy demand.

If your organization is going to take measures to reduce peak demand, you need to make sure your energy supply contract allows you to benefit financially — rather than potentially being penalized by your supplier. Demand-side reduction efforts should be negotiated into your supply-side contract. It’s also important to run a competitive bid process every time you seek a new supply contract, rather than allowing your current supplier to set the price. Doing so will help you secure the best deal for each new contract.

Tip No. 4: Plan ahead

Another common pitfall in energy procurement is waiting until just before the current contract expires to start looking for a new one. The energy market is seasonally cyclical and impactful market events can drive prices up or down for short periods. To avoid paying too much for your next contract, get an early start and take time to really dig into your options and review pricing. This is where working with an experienced energy procurement and management firm can yield big returns. Tracking the energy market daily and understanding how certain events will impact pricing over time are both critical to long-term buying success.

If your organization requires stakeholder approval of energy contracts, be aware of that and secure that approval in advance. This allows you to move quickly when the time is right, so you can lock in the best price. Not having the approval process in place could translate into delays and lost opportunities in terms of pricing, as prices are often only valid for a short period of time.

Purchasing with strategy

Your energy purchasing strategy is dependent on many things, most of which are out of your control. Weather, government regulations, demand charges, and new energy developments are all issues that can impact pricing for commercial customers. Taking control of your procurement options with thoughtful research, meaningful partnerships, conscious goal setting and extensive planning can help you make the right purchasing decision for your building. And remember that you don’t have to do it alone. Working with an experienced energy consultant can help you streamline the energy supply process to increase your savings.

Advantages of double-wall brazed plate heat exchangers in potable water applications

By: SWEP North America

Brazed plate heat exchangers (BPHEs) are one of the most efficient ways to transfer heat.  They are designed to provide unparalleled performance with the lowest life-cycle cost. Choosing brazed technology for your next heating or cooling project will bring many benefits, including savings in space, energy, and maintenance across HVACR and industrial applications.  BPHEs are quickly winning ground, thanks to their many advantages over older technologies (i.e. plate & frame, shell & tube), and consistently deliver successful results in many types of applications and projects.

BPHE technology embraces double-wall models suitable for a wide range of applications such as hydronic heating, district heating, radiant floor heating, gas boilers, solar domestic hot water systems, snow melting, heat pumps, and domestic and potable water heating systems.  They are suitable for many industrial applications too, including food, pharmaceuticals, chillers, transformer oil cooling, and lubricating oil cooling. Double-wall, high-quality BPHEs combine the high efficiency and compactness of the BPHE with the advantages of double-wall technology.  Double-wall BPHE technology ensures that liquids do not mix and makes any internal leaks visible – important factors in applications where safety is a priority.

While double-wall BPHEs are well established in European installations, they have also already been proven in applications in North America.  One example is a biomass application for a large pellet manufacturer in the US, where a solution for cooling gearbox oil was being sought. Traditionally, the oil was cooled with a fan coil that lost energy to the atmosphere.  Installing a double-wall BPHE instead enabled the energy to be captured from the hot oil and used to heat domestic hot water. The energy saved with this BPHE solution was around 27,000 kW per year (92127834 Btu/hr.), giving the end user payback in 20 months.  In another North American case, double-wall BPHEs provided an optimized solution for a leading water heater manufacturer. Here, they were used in instant water heating applications and domestic hot water for tank heating. When combined with a BPHE, the boiler need not heat the water to such a high temperature to achieve a suitable temperature for the end users.  BPHEs have therefore been able to displace older shell & tube technologies in these types of applications. The double-wall BPHE can heat water to the desired temperature so rapidly and effectively that it is not only more energy efficient, but also imposes a smaller load on the boiler.

Above all, however, is the huge benefit of double-wall BPHEs in preventing water contamination in potable water applications.  In the Netherlands, for example, the government requires double-wall technology in district heating networks. On safety grounds, this technology has been used in a large majority of tap water heater installations over recent decades.  At first glance, the heat transfer task in this case does not appear particularly complicated. However, there are two challenges. First, Dutch law prohibits single-wall heat exchangers in tap water applications with heat loads over 45 kW (153546.39 Btu/hr.).  Second, the maximum pressure drop on the hot water side must not exceed 15 kPa. The double-wall BPHE has been proven to solve this problem in the most efficient and reliable way possible. Should a leakage occur, for example due to corrosion, water will seep out between the vented double walls to the atmosphere.  The water seeping out from the BPHE gives a visual alarm that something is wrong. Contamination of the tap water by the heating water delivered by the energy company can therefore be prevented. The double-wall philosophy could assure the quality of the tap water for all European citizens, but the Netherlands is still the only market to have adopted this very useful technology to a significant extent.  However, awareness of the technology is increasing in other countries. The German government, for example, recommends double-wall technology in tap water applications without making it a legal requirement.

When considering double-wall BPHE suppliers, look for those combining extensive expertise with a wide product range.  If you are also seeking the additional security of third-party verified performance, check that your BPHE supplier can offer AHRI-certified double-wall products.  AHRI’s certification programs are well-recognized performance verifiers for heating, air conditioning, and commercial refrigeration equipment. Products connected to a program are tested annually by independent third-party laboratories, contracted by AHRI, to verify that they conform to performance ratings specified in data sheets and selection software.  This enables buyers to evaluate and make a fair comparison when selecting products for their HVAC installations.

 

Conclusion

Double-wall BPHEs are designed to deliver high thermal efficiency while at the same time providing a leak detection feature – this proves to be an excellent solution for potable water applications.  Contact SWEP today to find out more about our range of double-wall BPHEs and how they can provide optimized solutions for your applications!

 

Ice Rink Update

Technical Safety BC’s recent report on the Fernie Arena tragedies underlines the safety risks inherent with ammonia ice plants. A small leak in a chiller tube caused a 9 lb. release of ammonia into the mechanical room which quickly overcame those working there.

To quote TSBC, “Ammonia releases from refrigeration systems can cause injuries to employees, emergency response personnel, any public using the facilities and those living in communities surrounding the facilities.  When released from a refrigeration system, ammonia vaporizes into a toxic gas. It is very corrosive, and exposure to it may result in chemical-type burns to skin, eyes, and lungs. It may also result in frostbite, since liquid ammonia’s boiling point at atmospheric pressure is -28°F. Ammonia has a high affinity for water and migrates to moist areas like the eyes, nose, mouth, throat, and moist skin.  Exposure to low concentrations can cause headaches, loss of the sense of smell, nausea, and vomiting. Higher concentrations result in irritation to the nose, mouth, and throat causing coughing, wheezing and damage to the lungs. Very high concentrations of ammonia can be immediately fatal.

Ammonia is flammable and extremely reactive as it readily combines with other chemicals to form other potentially harmful substances or explosive mixtures.  Material commonly found in refrigeration machinery rooms such as oils can react with ammonia increasing the fire hazard. In addition, strong oxidizers, such as chlorine or bleaches, can form explosive mixtures when they come into contact with ammonia.”

Work Safe BC calls ammonia levels of 300 ppm or more to be, “Immediately dangerous to life and health”.

The Trane white paper on Ammonia-Free Ice Rink Refrigeration, shows a leak of just a half pound is enough to raise the ammonia concentration in a typical equipment room above the 320 ppm RCL (Refrigerant Concentration Limit). Also notice it would require 718.8 lbs. of Trane’s R513A synthetic refrigerant to reach our 72,000 ppm RCL (well above the charge we have in our entire system).

Trane packaged chiller systems dominate the air-conditioning marketplace. As well our chillers are used in many institutional, industrial, laboratory, and critical cooling and heat recovery applications. Trane has built chiller systems for over a hundred years – it’s our bread-and-butter.
