Investing Energy Savings in Your Campus Facilities

November 11, 2019

campus map

Colleges and universities throughout the country are taking a hard look at their facilities. Most of these institutions have buildings that are at least 30 years old and they need to be updated. Today’s Gen-Z students also demand certain amenities that schools struggle to provide. Couple these problems with utility costs that continue to rise and shrinking operational & maintenance budgets, many of our colleges feel like they are stuck between a rock and a hard place. They know what needs to be done and work hard to stretch every dollar to get things done, but the money only goes so far.

College leaders and governing board members struggle to develop a financial model that generates adequate funding for needs. And so, buildings continue to be neglected because tight budgets have forced the administration to take a deferred maintenance approach to maintaining their facilities. After all, “deferred maintenance” is sounds much better than “neglected maintenance.” This takes a heavy toll on campus facilities and does not help with the enrollment struggle of trying to attract and retain Gen-Z students. After all strong enrollment is essential for the financial health of a college or university.

Energy Conservation as a Solution

There is a nontraditional solution that can redirect monies already in your budget to pay for facility improvements and upgrades. Many campuses are full of building equipment and systems that are outdated and energy thirsty. Deferred maintenance and other budget issues often make it hard to upgrade these systems. But replacing energy-thirsty equipment with newer energy efficient systems can save money in utility costs. Done properly, upgrading these outdated systems can actually pay for themselves and fund other improvements. Most importantly, this approach complies with both state and federal statutes related to energy services and performance-based contracting.

Here is how to make it work:

  • Find a professional energy service company (ESCO) that can help you develop a strategy for improving your institution’s financial health.

  • With the ESCO’s help and expertise, conduct and energy audit. A comprehensive energy audit of your college facilities will help you identify inefficient systems and equipment that is costly to operate.

  • The ESCO will develop a turn-key solution that may develop into a project that is completely “paid from energy savings.” The key to making this work is to find an ESCO consultant that you can trust. One who is focused on addressing your unique needs rather than using a “one-size fits all” approach.

  • The improvements often include upgrades to the mechanical systems, lighting, water fixtures, windows, and other building envelope upgrades. These can be paid for over time with the savings generated in your monthly utility bills.

Benefits from an Energy Conservation Project

Below are some of the benefits that have been expressed by higher ed leaders who have utilized a “paid from energy savings” approach:

Become Better Stewards of Resources

  • By addressing needs and improving living conditions on campus, the college is becoming a better steward of resources.

  • Using sustainability and “green” initiatives to generate a new revenue stream can get donors excited and more willing to contribute.

  • It creates practical “asks” for donor funding of tasks, which can be marketed as “the gift that keeps on giving” back to the university through utility savings. This method speaks to a college’s commitment for the long run!

Attracting & Retaining Students, Faculty, and Staff

  • Improving the quality and comfort of the learning environment goes a long way to attract Gen-Z students. In addition, upgraded facilities make it easier to attract and retain quality faculty and staff.

  • Implementing an energy conservation program shows that your institution is being a good steward of the environment. This helps promote a culture of social responsibility on your campus. It is a testimony to a forward-looking college or university.

No Donor Gifts or Operational Funds Required

  • Saving energy means saving money. An energy conservation program can be implemented in a budget-neutral manner. The improvements are paid for from the utility savings associated with the program.

  • Since the turn-key solution offered through our program does not have up-front costs, the project demonstrates fiduciary responsibility of donor gifts and operational funds.

Facility Maintenance Benefits

  • Implementing an energy conservation program allows you to update your aging or failing building systems using existing utility dollars.

  • Upgraded building systems reduces the need for outsourced maintenance, which reduces maintenance costs. It also frees your facilities team to focus on preventive maintenance.

Environmental Benefits

  • By conserving energy, you reduce your campus carbon footprint, which contributes to a better environment, both locally and globally.

Find Dollars In Your School Budget for Facility Upgrades

January 10, 2019

The following Navitas article was published in the January edition of the Missouri Association of School Business Officials (MoASBO) Enews publication with the title “Finding Dollars Within Your Existing School District Budget to Re-Invest into Facilities”. MoASBO is a professional association of Missouri school district officials and employees whose expertise is in the area of school business administration. (https://www.moasbo.org)

When looking for ways for your school district to operate more efficiently, the “rock” to turn over with the greatest amount of savings is most likely energy management. All around us, embedded in every building is a vast, untapped energy resource: efficiency. Many times, this resource is hidden, ignored, or misunderstood by school districts that are sitting on the potential.

Today, school districts in the United States spend about $8 billion annually on energy costs alone, which is more than the cost of textbooks and computers combined. When a school district receives the utility bills, they are sent to Accounts Payable for processing. Often, there isn’t enough time to take a hard look to see where the school district could be saving money.

Young Man Businessman Opening Letter with Shocked Expression

Every year, K-12 facilities waste millions of dollars in excess energy consumption. Those dollars may take the form of lost heat through walls, windows, doors, and roofs. By being intentional about cutting utility costs, school districts can easily reap savings that can be used to help fund greater needs within the district.

Excess funds that districts are sending to the local utility companies can either be invested back into the facilities to address deferred maintenance issues, or possibly as a new source of funding for other pressing instructional needs.

Top Energy Wasters

Some of the top energy wasters include:

  • Inefficient Energy Managements Systems – a poorly configured energy management system can waste 20% – 25% of your gas and electricity dollars.
  • Lack of Central Plant Optimization – The typical workhorses of your heating, ventilating, and air-conditioning system are boilers, chillers, pumps, and cooling towers. If these systems are not properly optimized, they can be very costly to operate.
  • Postponed Preventive Maintenance – Even the most routine maintenance, like changing filters, can greatly enhance the energy efficiency of a building system.
  • Inefficient Lighting Systems – Lighting systems have made tremendous advances in technology and efficiency in recent years. Systems with built-in occupancy control, daylight sensors, and automatic dimming are cost-efficient ways to reduce electricity consumption and demand.
  • Outdated Plumbing Fixtures – K-12 facilities are large consumers of water. Installing water conserving plumbing fixtures can result in significant savings.
  • Wasteful Boiler Systems – Boilers are sized to meet the greatest potential demand on the system. Unfortunately, this means that for 90% of the year they are oversized.

Industrial Boilers

Over the years of conducting energy audits, we have encountered a lot of strange things that leave us scratching our heads. Some of the time, these items were known to school administrators and facility directors, but the district lacked funds to address them. Other times, these items were unknown and had been issues for years!

Below are a few of those “head scratcher” situations. Are any of these occurring in your buildings? What other problems might be lurking and causing issues with your utility bill?

  • Building controls with setback temperatures for the evening that were swapped between summer and winter set points. This meant that during the winter the building was heated to 80°F at night and during the summer it was cooled to 65°F at night.
  • Heating/cooling equipment that was being maintained to exactly 70°F. This meant the units had to constantly swap between heating and cooling to maintain the temperature at exactly 70°F all year.
  • A snow melt system that was left on during the summer because a breaker was mistakenly switched on.
  • Underground steam piping that leaked so bad that the snow melted and would not build up on the ground above it.
  • A fountain in front of a building that had a water overflow sensor malfunction that caused the fountain to constantly drain and fill for an entire summer.
  • Underground hot water piping that had such significant leaks it meant continuous refilling and heating of the hot water tanks.
  • Missing filters in the air handlers of a science lab that caused the need for coil replacements because they were being clogged.
  • Windows that had air gaps between the window and wall big enough to put your finger through.

Start Saving Money Now

The money to make the appropriate modifications is already available in your current budget, if you are willing to find it. Here are a few suggestions:

  • Conducting an energy audit of your school facilities will help you will find inefficient systems, infrastructure, and equipment that is costly to operate. By gaining a deep understanding of how these systems work, how people interact with them, and keeping the focus on improving performance great savings can be achieved.
  • Providing proper equipment training to your maintenance staff will often pay for itself. When maintenance staff know how and when to provide maintenance and modifications building equipment and the energy management system, it results in energy savings.
  • Many times, the cost to upgrade HVAC systems, lighting, windows and roofs, can be paid for over time with the saving generated in your monthly utility bills.
  • Don’t just pay the utility bills – track them. Ensure that you have developed an energy baseline before you start your projects, so you can track your savings. Also, when you track utility bills, be sure to benchmark your utility consumption against other K-12 facilities in your geographic area so can compare how you are doing.
  • Find a professional energy services firm that can help you integrate the process. Ultimately, there are many firms in Missouri that have expertise in the energy field. Contact your energy services firm to discover how much funding your school could find with improved energy efficiency!

Data Analytics and the Renewal of Buildings

August 28, 2018

The following Navitas article was published in the Summer 2018 issue of the Missouri School Plant Manager magazine, published by PTR Communications. The Missouri School Plant Manager magazine is the official publication of the Missouri School Plant Manager’s Association (http://www.mspma.com). If you would like a PDF of the article, click here.

Data Analytics Screen Shot

Building owners and operators are all eventually challenged with aging facilities. Often patrons or customers of those buildings are focused on the aesthetics and functionality of the interior space, but operators know aging facilities present more challenges that just the aesthetic. I have heard many school administrators lament over community members that oppose school building projects, especially when a building must be abandoned. The reasons for this are wide-ranging and mixed, from genuine financial concerns to pure nostalgia for the building.

Regardless, wherever community concern is generated, we in the facility management industry are often tasked with recommending and justifying decisions made around building projects – many of which an average patron of the building will never recognize. One way we have found that can help justify actions and actually save money at the same time is through the use of data analytics. The added insight the data provides on how a building is operated can justify decisions on how a building is run, diagnose comfort concerns from occupants, identify humidity issues, improve and optimize maintenance plans, etc.

Additionally, in the last few years, the ability for facility managers to collect and use data have helped many school districts decrease their utility consumption by 20-35%. While energy costs may not be top of mind to most school building operators, what benefit could the decrease of payments to the utility return to your school? What flexibility would those savings provide you on facility projects?

Figure 1: Before Optimization

The use of data analytics has greatly helped building operators understand what is happening in their building. By gathering data points in real time, operators can understand how a building consumes energy. With that information, informed decisions can be

made on how to decrease energy use while maintaining comfort for building occupants.

Take the example, shown in Figures 1 & 2, of a building before and after optimization. Figure 1 shows a building with a typical spike in electric consumption during the day and decreased usage in the evening. However, this building’s temperature set points maintained 70°F all weekend instead of going into unoccupied mode as intended.

1. Temperature set point was inadvertently changed to 70°F all weekend.

2. Heating units stagger during the weekdays but are on most of the time over the weekend.

3. As a result of increased usage, electric consumption increases dramatically for the weekend. This consumption can be quantified to determine the financial impact of this one building automation decision.

Figure 2 depicts the graph of the electric consumption after building optimization. Here you can see a dramatic decrease of electric consumption over the weekend.

Figure 2: After Optimization

4. Room space temperatures gradually decrease until reaching 60°F, then are maintained at 60°F until Monday morning.

5. Units on/off status. Note the units stagger on and off to maintain temperature as needed.

6. Electric consumption is very low during unoccupied hours, with a few spikes to account for units firing to maintain 60°F.

We have seen school buildings operate in both of these scenarios, as well as unintended operation of buildings during snow days or holiday breaks. Aside from the difference in energy costs, there is the potential to decrease maintenance costs as well. Upon implementation of data analytics, one school recognized some inefficiencies in their system, and made changes that changed their equipment run times from 7,000 hours annually to 1,000 hours – a decrease of 85%! If equipment could effectively run that much less, how much would your school district save in maintenance? How many fewer failures and service calls would be required? How much longer would your equipment last? How much could your finances be impacted if equipment performs better & lasts longer?

Data analytics is also helping facility managers identify hard to diagnose issues. Take the graph shown in Figure 3 as an example. This graph depicts actual electricity consumed over ten days. The first two days show the electricity consumed over the weekend at an average of 43 kW. As staff arrives on Monday morning, electricity spikes up as lights, computers, coffee pots, etc. are fired up, then the electric consumption drops back to around 43 kW at night. This pattern is consistent for about a week, but for a building this size we would expect the overnight electric consumption to be significantly less.

Figure 3: Elementary School Electric Profile

We noticed this abnormally high consumption and contacted the facility director. We determined that while the building automation set the temperatures back at night, the vestibule cabinet unit heaters had a high temperature set-point, and essentially were attempting to heat the entire building during unoccupied hours. By simply adjusting the thermostats in the cabinet heaters, the building reduced the baseload by about 29 kW, resulting in over $2,000 per month saved on their electric bill. Without data analytics, this problem may never have been diagnosed.

Other problems we’ve found through data analytics that might never have been diagnosed include:

  • Heating and cooling at the same time
  • A snow melt system powered on during the summer
  • Summer and winter night setback temperatures swapped (during winter unoccupied hours, the building would heat to 80°F instead of maintaining 60°F
  • How one room remaining in occupied mode overnight can cause a large cooling tower with over 30 hp of pump and fan motors to remain in operation
  • Wireless thermostats losing communication, which caused heat to be engaged during cooling months
  • How cleaning staff pushed every override button in a building over a 20 minute period every night, causing a spike in electricity demand, and a 400 ton chiller to be unnecessarily be engaged after 11:00 at night.
  • How much it costs the district to operate HVAC equipment in a gym for the community men’s Sunday basketball league.

The role data analytics can play for a school district is partly to catch errors and inefficiencies, but also to show the district how much it costs for certain activities or behaviors. From there, district personnel can make informed decisions on how their buildings should be operated, or how much they should be charging for the use of facilities.

What could data analytics show about your buildings? What is happening inside your buildings when they’re unoccupied? Could a platform like this help you diagnose issues you think you have? Or issues you don’t yet know about?

Ultimately, energy savings strategies like the ones discussed in this article can play a part in funding the renewal of your buildings. This can allow you to keep as much money funneled into education as possible, instead of maintaining old, inefficient equipment. Talk to your energy services provider and consultants to determine how data analytics can be of value to your district.

5 Energy Efficient Ways to Beat the Summer Heat

July 10, 2018

When the temperature outside soars, it’s hard to keep things cool inside without busting your utility budget. Running the air conditioner full blast may seem like a really good idea until you see the next electric bill.So, what can you do to beat the summer heat and not kill your budget?

Here are 5 energy efficient and utility budget friendly ideas.

1. Get a Programmable Thermostat or a Smart Thermostat

Many people think that its cheaper and more energy efficient to leave your air conditioner running on high all the time, even if you aren’t home. But it’s not true.

The amount of energy an air conditioning unit uses to cool down a space that’s been hot all day is actually less than the amount of energy needed to keep that space cool all day long. That means that you can save money if let your home get warm while you are gone for the day.

But you also don’t want it get too warm in your home. Letting the temperature rise above 80°F-85°F can cause damage to candles and other things sensitive to temperature.

This is where a programmable thermostat or smart thermostat can really help. Many people use them to cool down their house right before they come home, which maximizes their efficiency.

The beauty of these thermostats is that once you it’s set up, you don’t have to think about it again until the seasons change. No more lying in bed at night and thinking “did I turn the thermostat down?” Its already taken care of.

2. Use Fans Along with Your Air Conditioner

It may seem counter intuitive that using electricity for a fan while your air conditioner is running would save you money. But its true.

Fans move the air around and can move cool air from one area into another area. Fans also create a breeze, which feels good on the skin and help remove body heat.

Many homes have areas that seem to stay cool, even during the heat of the day. Using a fan to help move this cool air, helps your air conditioner maintain a comfortable temperature.

You may even find that you can turn your air conditioner up a few degrees and still be comfortable.

If you want more information on how to use fans to keep your home cool, check out these links:

  • https://www.energy.gov/energysaver/home-cooling-systems/fans-cooling
  • https://www.energystar.gov/products/lighting_fans/ceiling_fans

3. Grill and Keep the Heat Outside

Most cooks know that using an oven will heat up the kitchen. While this can be nice in the winter, it can be brutal in the summer. So why not keep the heat out of the kitchen and use the grill on your patio. Not only is it fun, it will save you money on your utility bill.

4. Keep the Shades Drawn and the Curtains Closed

Its pleasant to see a nice bright sunny room. It makes the room appear warm and inviting.

Unfortunately, all that sunshine is also bringing a lot of heat into the room. In the winter, this is great, but in the summer, it can be very uncomfortable. It also puts an extra load on your air conditioner as it tries to keep your house cool.

Just closing the curtains or lowering the shades during the hottest part of the day can make a room feel much cooler. It will also help you save on your utility bill because it helps give your air conditioner a break.

5. Turn off Electronic Devices

Have you ever noticed how hot your computer gets? What about your TV or your gaming console or your stereo?

Electronics give off heat. That’s why so many of them have vents on the side or little fans in them. It may not seem like a lot, but it all adds up.

The more electronics you have, the more extra heat you have in your living space. Turning off these devices when you aren’t using them will help keep your space cool.

Finding Dollars Within Your Existing School Budget

October 26, 2017

When looking for ways for your school district to operate more efficiently, the “rock” to turn over with the greatest amount of savings is most likely energy management. All around us, embedded in every building is a vast, untapped energy resource: efficiency. Many times, this resource is hidden, ignored, or misunderstood by school districts that are sitting on the potential.

Excess funds could also be reinvested back into a district’s current facilities to work towards a zero net-energy environment. With zero net energy the total energy used by the building is equal to the renewable energy created on the site.

Some of the Top energy wasters include:

  • Inefficient Energy Managements Systems – a poorly configured energy management system can waste 20% – 25% of your gas and electricity dollars.
