Cogeneration technologies are poised to play an increasingly important role in the energy mix of the future.

Cogeneration technology, including combined-heat-and-power (CHP) systems and district heating-and-cooling (DHC) systems, offers many economic and environmental benefits compared to conventional methods of energy production. By simultaneously producing thermal and electric energy from a single fuel source, such as natural gas or biogas, the systems require less total fuel to produce the same amount of energyand generate enormous cost-savings potential.

Because less total fuel is consumed, greenhouse gas emissions and other harmful air pollutants are also reduced. In fact, CHP technologies are estimated to reduce carbon dioxide emissions from new power generation by more than 10 percent by the year 2030.

Cogeneration of energy on-site can also support corporate environmental goals for sustainability and use of renewable resources, while simultaneously reducing the dependence on other regions or countries for imported energy. By increasing energy efficiency and helping to offset costs, cogeneration can give businesses a competitive edge.

Heat Sources Provide Opportunities Cogeneration systems achieve more than 90 percent energy efficiency by extracting and using thermal energy produced during the generation of electricity, heat that would otherwise be wasted. Systems based on gas-fueled reciprocating engines include several potential heat sources, and the ideal use depends on aligning the heat requirements of the facility with the available heat sources on the system.

Exhaust gas, for example, reaches temperatures exceeding 450 degrees Celsius, hot enough to support an absorption chiller, which, in turn, creates cooling energy. Sources such as the lube oil, jacket water or high temperature air/fuel mixture, on the other hand, reach temperatures closer to 90 to 200 degrees C, which makes them ideal for industrial processes, drying processes, building heat and steam production. Other heat sources below 90 degrees C include the low-temperature air/fuel mixture, calorific value boiler and radiator, which are ideal for drying processes, underfloor heating and return temperature heat.

When using all the available heat sources, a cogeneration system from MTU Onsite Energy can achieve overall efficiencies of up to 96 percenta best-in-class rating and a major improvement compared to conventional methods of energy production.

Site-Specific Factors To ensure optimal performance and efficiency, several factors must be considered before installing a cogeneration system.

Methane Number Most gasses are a mix of methane, hydrogen and other gas constituents. The methane number (MN) provides an indication of the gasses, tendency to knockor combust prematurelywhich can damage the engine. For example, pure hydrogen would have an MN of 0. A low MN signifies an extremely explosive gas with the potential to ignite before the spark plug fires, resulting in uncontrolled combustion. Pure methane (CH4), on the other hand, would have an MN of 100. Gasses with a high MN are less explosive, and therefore less likely to ignite before the spark plug fires, resulting in a more controlled combustion.

Natural gas has an MN of 80 to 90, making it ideal for controlled combustion. Gas composites (such as biogas) have an MN between 120 and 130. Understanding the knock resistance is important when specifying an engine for a gas-powered cogeneration plant.

Elevation Smart marathon runners train for the race conditions theyre going to runespecially if higher elevations are involvedotherwise, theyll never be able to catch their breath. Similarly, the altitude of an installation site can significantly influence the power output of a cogeneration system. As elevation increases, air density decreases, and engines need air to breathe.

When specifying a gas-powered cogeneration system for a high-altitude installation, proper preparation and planning are essential to avoid operating below the engines maximum power rating. For instance, a gas-powered MTU Onsite Energy Series 4000 cogeneration system can operate at full load in altitudes up to 6,700 feet without any derating simply by adjusting its turbocharger nozzle ring, which essentially enables the engine to take deeper breaths.

Temperature Like elevation, the ambient temperature of an installation site can significantly impact power output. This is because air volume increases as temperature rises. In warmer climates, if the ambient temperatures exceed a certain point, it can become difficult to provide the necessary volume of intake air for the engine to perform optimally, resulting in lower power output.

Cogeneration system manufacturers frequently offer different equipment models to account for these variations. And in some cases, the equipment will be installed in a temperature controlled (air conditioned) room to help offset the impact of excessive ambient temperatures.

Humidity Air humidity and dew point must also be carefully considered when specifying a cogeneration system. Dew point is the saturation temperature for water and air, the point at which water droplets begin to condense and form. This measure of moisture varies according to atmospheric pressure and humidity. To ensure maximum power output, specifications must include an analysis of humidity and its related dew point temperature based on the climate of the installation site, along with other factors such as methane number and type of gas. Similar to temperature, cogeneration system manufacturers frequently offer different equipment models to account for these variations.

The need for highly efficient electricity, heating and cooling is universal. Cogeneration is a powerful solution that can generate cost savings and environmental benefits just about anywhere in the world. A wide number of applications utilize cogeneration systems, including office buildings, condos, shopping centers, schools, community pools and dairy farms. The key to a successful cogeneration project is proper specification and planning, which should take into account climate- and site-specific factors such as methane number, elevation, temperature and humidity, in addition to thermal and electric requirements. While determining if a facility is an ideal candidate for CHP is an extensive process, exploring the option is a smart move for any facility with simultaneous needs for heat, cooling and electricity. The potential gains of CHP are too great to be ignored.

The West Virginia School Building Authority is giving $6.7 million in Major Improvement Project grant money to public schools in 10 counties.

The grants, awarded at the boards quarterly meeting on June 26, help public schools pay for construction and renovation projects statewide.

Counties requested a total of $9 million from the SBA in this years Major Improvement Project grant cycle.

Fayette County received the $1 million it requested for renovations to Oak Hill High School to accommodate an increase in enrollment from the closure of Fayetteville High School. The work will include a new safe school entrance with a mantrap and visitor processing area, office relocation and expansion, cafeteria expansion, and the creation of a new STEM/STEAM lab in the former shop area. The school system will contribute $397,482 of its own money to the project.

Webster County is getting $930,920 for new ceilings, lights, and lockers throughout the interior of Webster County High School. The project replaces ceilings and lights damaged by a leaking roof that was replaced in 2013. Webster has $10,000 in local funding to complete the project.

Pocahontas County requested and received $925,443 for renovations to Pocahontas County High School that include replacing the sewage treatment system, water tank, and a building-wide fire alarm, as well as new garage doors, windows, entry doors, and a roof over the storage area in the vocational building. SBA documents note the West Virginia Division of Environmental Protection has fined Pocahontas County for noncompliance and faulty operation of the existing sewage treatment system. They also note the county cannot contribute any local funds because voters on Nov. 8, 2016, rejected a capital improvement levy which, in partnership with a SBA Needs Grant, would have resulted in $18 million worth of improvements throughout the county.

Taylor County will use $859,682 plus $300,000 of its own money to add three classrooms and a student restroom to West Taylor Elementary School. Then the system can move 40 Pre-K students that are housed in a collaborative head start program located at a church in Webster, making room for more 3-year-olds to enter Webster Head Start.

Monongalia County sought and received $743,211 for HVAC renovations and installation of new controls and rebalancing of all associated systems at the 26-year-old Mountainview Elementary School. The school system is paying 25 percent of the project cost, which amounts to $247,737.

Lincoln County asked for and received $600,000 to replace sewer plants at Midway Elementary School and Duval PreK-8 School to fix health and safety violations. SBA documents say the Duval facility has been warned it could be permanently closed if its systems retaining wall fails. Lincoln is paying 18.73 percent or $138,306 of the project cost.

Pendleton County intends to put a $50,000 federal Qualified Zone Academy Bond with the $592,353 MIP grant to pay for self-contained heating/cooling units plus duct work and controls in the gymnasiums at Pendleton County Middle/High School and Brandywine Elementary School. The current systems at those schools only heat the facilities and do not provide adequate ventilation or cooling or meet the current standards of the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

Mason County was awarded $384,154 and with $96,038 of local funding will replace and upgrade the HVAC at New Haven Elementary School, Hannan Jr./Sr. High, Roosevelt High School and Point Pleasant Primary.

Mercer County will use $280,830 from the SBA and $25,000 of its own money to renovate restrooms at Mercer Elementary School grades 3-5, including installing adequately equipped stalls to serve students who are wheelchair users or who require the assistance of an aide.

Four counties Kanawha, Cabell, Mingo, and Tucker did not get any of the funding they requested. According to an attachment to the SBA boards meeting agenda, Kanawha County had asked for $433,740 to help replace some windows at Horace Mann Middle School. Cabell County applied for $375,875 to fund half the cost of replacing a cooling tower at Cabell Midland High School. Mingo County had sought $796,776 to replace through wall HVAC units on the second floor of Gilbert Elementary School while salvaging parts for existing units on the first floor. Tucker County had requested $79,932 for masonry cleaning and sealant to prevent water infiltration and damage at Tucker County High School.

Staff comments in the agenda indicated that the other projects might be judged more meritorious than those not receiving funding. In other cases, the projects might have met only a minimum number of criteria used to evaluate the merit of the project.

When Physical Plant Department (PPD) professionals with varying areas of expertise come together, amazing things can happen. PPD Engineering & Energy Services (E&ES) and the Area 1 maintenance group collaborated on an in-house project to upgrade the controls for the heating, cooling, air conditioning and ventilation (HVAC) system at Dane Smith Hall, a 20-year-old building. For the first time, two PPD groups, carried out a large and complex project avoiding contractors, change orders and the complications that can occur while working with entities outside of the University.

This $130,000 project was designed by the engineers in E&ES and the installation was performed by electricians, HVAC technicians and plumbers employed by PPD. Overall, the final cost of the project was $6,000 lower than budgeted, even with the added scope of work due to cost savings.

When we realized we were going to save so much money, we were able to include a lot more upgrades to the building systems than we initially anticipated, said Tommy Tafoya, E&ES manager.

State-of-the-art Variable Frequency Drives, HVAC controls, 90 valves for zone controls and 12 energy valves were installed to improve the efficiency of the six air handlers located in Dane Smith Hall. Area 1 maintenance was also able to explore and document where every controller and valve was located while troubleshooting problem areas based on their knowledge of the buildings unique set of circumstances.

Richard Van Damme, master HVAC tech in Area 1, said it was a nice change to be involved in every aspect of the project because it allows for the maintenance group to have a better understanding of the new technology and how its working in the building.

Now we know where every access point is so we can get to the problem quicker and ultimately provide a better service to our students and staff, said Van Damme.

With the new technology, it is anticipated that the building will require less electricity, steam and chilled water from the Ford Utilities Center, the Universitys power plant.

The most expensive part of operating a building on a daily basis is moving air. In Dane Smith Hall, the air handlers were running at about 68 percent of full fan speed capacity before we upgraded the system, and now they are running at 47 percent. A huge reduction in energy costs, explained Tafoya.

Automated Logic Controls, the computer program used by PPD E&ES allows technicians to see all spaces in the building to monitor the temperatures and the details of how the air-handlers are functioning. From a remote site, technicians can see if a classroom is too hot or too cold and can adjust the temperatures from afar.

Consistent climate-controlled classrooms, energy efficiency, and a complete working knowledge of the buildings systems for maintenance are the main benefits of this project. Another unexpected benefit was the workers were able to coordinate the work with the building occupants and build positive relationships.

There were no complaints throughout the project from occupants because the PPD staff made sure to communicate effectively and work around the classroom schedules, offices and computer labs. Everyone was really impressed by the professionalism of PPD, said Mark Orgeron, UNM graduate student and program coordinator in the UNM Provost office.

E&ES and Area 1 maintenance will begin their next collaborative project to upgrade the HVAC system at the Continuing Education building this summer.

Ashburnham and Ashby are among the seven communities to receive Green Communities Competitive Grants, which they'll use to make municipal building more energy efficient.

Sen. Anne M. Gobi, D-Spencer, a member of the Joint Committee on Environment, Natural Resources and Agriculture, announced the grants last Monday.

"Congratulations to these seven communities on being awarded grant funding through the Green Communities program," Sen. Gobi said in a statement. "It takes hard work on the part of municipalities to be eligible for these awards and these communities all did their part for the greater good on the Commonwealth and the environment."

Ashby was awarded a grant totaling $100,981. The money will be spent installing two new boiler systems, in Town Hall and the Ashby Free Public Library, said Town Administrator Bob Hanson.

The Town Hall heating system costs $65,071 and includes the large-capacity tank and new programmable thermostats. The town will spend $35,910 on a new boiler for the library.

Ashburnham was awarded a $217,300 grant to install a new heating and cooling system in the town library, which, according to Town Administrator Heather Budrewicz, is "by far" the least energy efficient building in the town.

The library's current 30-year-old HVAC system is "obsolete by today's standards," according to Budrewicz.

The grant will help the town inch closer toward a goal set in 2013 to reduce municipal energy consumption by 20 percent.

From 2013 to 2016, the town cut energy expenditure by 11 percent.

The new HVAC system is expected to reduce consumption by another 5 percent, bringing the total amount cut to 16 percent.

The HVAC system is expected to improve air quality in the library and make way for the removal of a 50-year-old underground oil tank. Town plans to apply for additional grant funding to finance the removal of the 3,000 gallon tank.

Green Communities Competitive grants are administered by the Department of Energy Resources.

Today, using the internet-of-things channel for building CRM victories seems to be a demonstration of more hype than reality. But there is vast potential, as early adopters reap wins, executives said at a recent Salesforce IoT demo.

No topic is off limits in this expert guide devoted to Salesforces much-hyped cloud-based BI platform.

"A lot of companies are still figuring out what their strategy is," Chris Weld, Salesforce IoT Cloud go-to-market director, told SearchSalesforce after presenting at the Boston stop of the Salesforce World Tour. While he acknowledged "not a huge amount of companies" have figured out a game plan for monetizing IoT, many Salesforce customers are trying to figure it out. Today's data systems are more agile, making them more conducive for IoT than just a few years ago, he said, and narrowing the scope of implementations that can affect business goals.

"[Enhancing] service is the low-hanging fruit we've seen for IoT," Weld added. "When you look at the operational change that's required for connected device data, that's where we've seen the highest value."

Some of the early adopters showcased in the Salesforce IoT demo included Emerson Climate Technologies, a connected-thermostat maker that added value to its product by conducting diagnostics on newly installed heating and cooling systems. While many new home heating and cooling systems feature potentially excellent efficiency specifications, Weld said in his presentation, improper installation begets poor performance and inefficient energy use. When a thermostat can measure efficiency and report performance metrics back to consumers, it's a reality check and new data point about the job a household's local installer performed.

In the future, Emerson plans to expand those diagnostics beyond new system installs to more general efficiency tests to help consumers conserve energy and lower their bills. In this way, the company hopes to prove to consumers the worth of its "smart thermostat" that typically costs twice as much as ones that aren't IoT-connected.

Also in the Salesforce IoT demo was a hypothetical large-format printer manufacturer using a combination of Salesforce IoT Cloud and Service Cloud features to track wear and tear on printers and help the businesses using the printers troubleshoot and replace parts as they wear out.

To figure out if investing in IoT to boost CRM capabilities is worthwhile, Weld said Salesforce customers he's worked with on IoT projects have to innovate rapidly. This means, typically, they have to fail fast and iterate again if the original concept doesn't quite work out in real-life tests.

They also need to add customer context -- examples include service history and service-level agreements (SLAs) in place -- to be able to act upon data the IoT sensors are outputting into the CRM system.

It is early in the game, early in the technology evolution. Wayne Kurtzmanresearch director, IDC

The most forward-thinking customers, Weld said, take advantage of real-time tech and thinking about IoT service implementations as proactive instead of reactive. "If we were doing this session four years ago, we'd be talking about Hadoop and HBase and [retrospectively analyzing] this incredible amount of data," Weld said. "We want to shift away from that and say, 'It's great to know what happened two days ago, but I really want to know what's happening right now so I can prevent problems before they occur.'"

The potential problem with IoT for CRM: thinking too big. Wayne Kurtzman, research director for social and experiential solutions at IDC, said the trick for companies to turn their CRM IoT pilots into money-making implementations is picking the right spots. Getting too ambitious too quickly can potentially eat up returns on investment before the projects get off the ground.

"That is a challenge," Kurtzman said. "It is early in the game, early in the technology evolution -- there's some risks at the beginning of any adoption curve. But if you play it right, if you play it where you are versatile, you can in fact reap significant benefits."

Variable refrigerant flow (VRF) technology is relatively new to the U.S., yet it has quickly become a very popular option in the commercial market.VRF is now moving into the residential market as well as more and more high-end homeowners and custom home builders are learning about the technologys ability to provide on-demand heating or cooling in multiple zones.

Many manufacturers are responding to this trend by offering VRF systems that are designed specifically for residential applications. These units often feature smaller footprints, lower profiles, and quieter operation as well as higher efficiencies, which are designed to appeal to the most discerning homeowner.

Homeowners do not lack options when it comes to choosing HVAC equipment for their high-end homes, so why should they consider VRF? It all comes down to efficiency, said CJ Corbet, southwest sales engineer, Fujitsu General America Inc. Our products, such as the J-II line, use algorithms to optimize highly efficient components, such as variable-speed compressors and fan motors, internal subcooling, and electronic expansion valve modulation, which help VRF systems out-perform traditional central heating and cooling in like-for-like applications.

But in residential applications, zoning is where VRF systems really shine, noted Corbet.

With VRF, we are able to put a unit in each room and only heat or cool the room that is occupied, he said. This eliminates heating or cooling rooms that arent occupied, which saves energy.

Energy savings, precise temperature control, and exceptional comfort definitely make VRF systems attractive to homeowners, said Chuck Hughes, director of commercial sales, LG air conditioning technologies, LG Electronics USA Inc.

Unlike conventional systems, which set a single temperature for an entire home, VRF systems offer the flexibility to create dedicated zones that allow for precise temperature control based on homeowners preferences. This lends itself to increased efficiency and improved comfort in a way that conventional systems simply cant rival.

Some VRF systems, such as LGs Multi V S line, also offer heat recovery technology, which enables homeowners to heat and cool different areas of their homes simultaneously. This is especially beneficial for homes that have gyms, for example, which the owners would like to keep cool during the winter, even though heat is required for the living areas.

In this case, heat recovery systems could repurpose the return heat from the gym to warm up the living area, which in turn, increases the energy efficiency, said Hughes. The return heat can also be used to heat a pool, which means homeowners are getting multiple uses for the energy they are paying for.

In addition to energy efficiency and personalized comfort, VRF systems offer design flexibility and quiet operation, inside and out, said Michelle Robb, director of residential marketing, Mitsubishi Electric US Inc. Cooling & Heating division.

VRF systems feature a compact footprint, which requires less outdoor space, and with long line lengths, the system allows maximum flexibility in installation, she said. There are also a variety of indoor unit styles available depending on the preference of the homeowner or the installation requirements.

While some might think VRF systems are expensive, they can actually cost less over the course of their lifetimes than traditional systems, said Robb. In a retrofit, there is existing infrastructure that may be reused depending on the choice of indoor units. In new construction, the initial cost of the equipment is typically slightly more expensive, but between reduced installation, labor costs, and operational costs due to impressive efficiencies, VRF systems can quickly become a more economical option all while providing better comfort.

Thanks to advancements in cold-climate technology, VRF systems can now be installed in just about any geographic area. For example, Mitsubishi Electrics S-Series and CITY MULTI VRF systems, both of which can be used in residential applications, can provide up to 100 percent heating output at 0F and 83 percent heating capacity at minus 13F, thanks to its Hyper-Heating technology.

With this technology, VRF systems are now a good fit for any home regardless of location, layout, or homeowner needs, said Robb.

It also does not matter whether VRF systems are being installed in existing homes or in new construction, as they work well in both types of applications.

With older homes, space often doesnt allow for the addition of bulky ductwork, but with our duct-free VRF, homeowners are able to preserve architectural features without requiring a redesign of the space or any major construction, said Hughes. In the case of new construction, owners desiring a clean aesthetic can eliminate building soffits for ductwork, which also translates to more usable square footage.

In Corbets opinion, all large homes would benefit from a VRF system rather than a traditional system, because the more rooms there are in a house, the better options there are for zoning.

VRF systems are also very well rounded for both extreme heating and cooling situations, so they cover a wide variety of geographical locations. And homeowners benefit from low energy costs and the comfort of on-demand heating or cooling through zoning.

And the good news for contractors is that VRF design is handled the same way in both residential and commercial applications.

Zone loads are required to select the appropriate unit for specific spaces, and once the units are selected, our design tool is used to lay out the configuration, said Corbet. That tool will catch any limitations that the project might exceed so that each project is designed correctly. For all VRF applications, controls are universal in that they can be used in any configuration.

While the controls for VRF systems are basically the same for all types of applications, residential controls may be slightly different.

Since VRF can be installed in large-scale commercial applications, such as school campuses, we offer additional controls for those types of installations, said Robb. VRF systems are also compatible with our kumo cloud programmable controller app, which offers remote control from anywhere in the U.S. through a smartphone, tablet, or computer. The interface has the ability to control multiple locations and indoor units, program cooling and heating events, indicate filter replacement, and monitor errors in the system.

For any VRF installation, be it residential or commercial, contractors still need to run a room-by-room load calculation to determine the number of indoor units required to appropriately condition the space, said Hughes. Since VRF systems can be ducted or non-ducted, contractors are able to select the systems that work best for each application, and end users can choose the indoor units that best complement their interior dcor. Combine that flexibility with zoning control, energy efficiency, and low maintenance, and there is no question that homeowner demand for VRF will continue to grow.

The Northeast branch of the Reading Public Library will be closed for the summer because the building will not have air conditioning.

The library is expecting the installation of a new heating and air conditioning system, but it won't be ready in time for the hot summer months.

Bronwen Gamble, executive library director, said the delay is frustrating for everyone involved.

"The city has been very proactive in trying to get this done, but it's a big project with many moving parts," she said.

The system will cost more than $150,000 to install, which is being paid for in a Keystone grant and community development block grants, each of which have specific requirements in the bidding process.

To lessen the inconvenience, Gamble said the Northeast branch will have outdoor hours on the front porch of the building where people can check out books, including new releases, and a selection of other media.

In addition to the regular hours, the Northwest branch will be open Mondays and Wednesday from 9:30 a.m. to 5 p.m.

Gamble said the newly revised bid specifications were released Monday and that the city is eager to expedite the process as quickly as possible.

"We're sorry for the inconvenience," she said. "We know it's frustrating. We're doing the best we can."

INDIANAPOLIS Chris Cunningham didnt have the honor of serving in the U.S. Armed Forces, but hes always had a deep respect for those who do. He gives veterans priority status when he hires, but he wanted to do more.

On Thursday, June 22, he and a crew from his company, Service Plus Heating, Cooling & Plumbing, spent the day in Franklin, Indiana, installing a new furnace and air conditioner for a disabled Marine.

The project, valued at $8500, is Cunninghams inaugural Salute to Service program, through which his company will annually donate and install a new air conditioner for a veteran in need.

This absolutely is a life saver for him, said Debra Gahimer, who nominated her husband for the program but didnt tell him about the possibility for fear of him being disappointed if he wasnt selected. After weeks of waiting for word, shed given up but took some comfort in thinking that whoever won surely needed it more.

Cunningham said it would be difficult to find someone who needed the project more.

Mark Gahimer left the Marines after only a year due to knee injuries but went on to spend 33 years in Indiana law enforcement, serving with the Capitol Police, Hendricks and Johnson counties, and the town of Whiteland. Now 60, he suffered a stroke last year. Hes diabetic, has recurring issues with dehydration, and severe back and neck issues. He uses a walker to get around. Summer is especially difficult as heat worsens his dehydration issues.

For the past three years, the Gahimers have relied on window air conditioners because they havent been able to afford to fix their central air conditioner. They dont really do that much good, Debra Gahimer said.

Cunningham was moved by Mark Gahimers nomination, but when he visited the couple to assess their needs, he said he had to do more.

Heres a guy whos spent his life protecting and serving others. First as a Marine and then as a police officer, Cunningham said. His a/c didnt work at all, and his furnace was 30 years old. Were going to rip out everything and give them a system that will help them all year round.

Mark Gahimer was a bit skeptical of the program at first, thinking it was likely a bait-and-switch kind of offer. He said he kept waiting for Cunningham to tell him what the catch was.

Id kind of forgotten there are still some really great people in the world, Mark Gahimer said.
