Platte County School District Receives FIVE Energy Star Building Awards

January 17, 2018

Congratulations to Platte County School District for receiving ENERGY STAR Awards on five of their schools. The school district was able to capitalize on their recent energy program with us to receive the ENERGY STAR certification on Pathfinder Elementary, Siegrist Elementary, Compass Elementary, Platte City Middle School, and Barry School.

Most people are familiar with the little blue ENERGY STAR mark on appliances and other products, but the US Environmental Protection Agency (EPA) also uses the program to certify buildings that are energy efficient. And, yes, they get an actual blue ENERGY STAR mark that they can display in a prominent location in their building.

The EPA has 21 building categories that can be used to rate how energy efficient a building is compared to all the other buildings of that type across the United States. A score of 50 is typical for most buildings and means that your building is only average in energy efficiency. A score of 25 means that your building is not very energy efficient and only better than 25% of all building of the same type nationwide. A building must receive a score of 75 or better to be ENERGY STAR certified.

Platte County School District has received ENERGY STAR certification on five of its schools, which is a HUGE achievement by itself. But they also have two schools, Siegrist Elementary and Barry School, which received scores above 95. That means that these two buildings are more energy efficient that 95 percent of all the schools of the same type in the whole United States!

Way to go Platte County School District!

Gladstone City Hall Gets New Rooftop Units

December 22, 2017

The City of Gladstone hired Navitas and its construction partner to replace the rooftop units on the Gladstone City Hall. Our crews were able to remove 10 RTUs and replace them with 10 new units in one weekend. You can also see that the City Hall is getting a brand new roof, which should be completed soon.

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.

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.

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. Every dollar used to pay an unnecessary high energy bill could be put to a much greater purpose – educating students.

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 a new source of funding for other pressing instructional needs.

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.

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.

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.

Outdated Plumbing Fixtures – K-12 facilities are large consumers of water. Installing water conserving plumbing fixtures can result in significant savings.

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. One of the tools to help you find it is an energy audit. 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.

Towards Greater Energy Efficiency: You’ve Already Made Some Crucial Decision, Whether You Realize It or Not

By Ryan Terry (rterry@navitas.us.com)

Are You Going to Make a Decision About Energy Efficiency? Whether you know it or not, you actually have made a decision on energy efficiency. Whether you have decided to do nothing, pursued a traditional process of repairing/replacing systems and equipment, or hired an expert to help you make your energy decisions, decisions have been made.

Have you made the right decisions? Are you as energy efficient as you could be? Are you doing everything you can to make sure your organization is successful?

Most older buildings were not designed with efficient use of energy in mind. In fact, even many of the newer buildings that were designed to be energy efficient are not constructed or operated as intended. Not only does this inefficient operation result in a larger “carbon footprint” but the fact is, inefficient buildings cost more money to run and are less comfortable for occupants.

Whether buildings are new or old, they can be energy efficient. Many schools have begun the transition from doing nothing to having their own staff implement energy-efficient strategies, to hiring contractors or maybe hiring an Energy Service Company. Each of these options may have different benefits, but all are better than doing nothing.

Many schools find themselves doing nothing and choose to close their eyes on the fact that their costs for utilities are high and continue to increase every year. Even though the potential for savings is there, they continue to have utility costs eat further and further into their budgets. They choose to not take the time to understand how much they spend on energy and how that compares to what they should be spending.

There may be other priorities and decisions that need to be made on things that feel more pressing. They continue to do nothing until they find themselves in a spot where other things are not as pressing, they get in financial difficulties, have pressing facility issues or learn something new that causes them to realize their energy costs are a problem.

How and Where to Start

First, take some time to try and understand your problems. Why are you interested in doing something about this? Did you decide you are spending too much on energy? Do you have other places you would like to spend that money? Talk to your administrators, facility staff and others that are impacted by the energy consuming systems you have in your buildings.

Consider talking to other professionals to get their perspectives. Architects, engineers, contractors and Energy Service Companies can provide you with knowledge and experience from their fields of expertise. Take the things you begin to learn and set out on a plan.

The next step involves defining a plan and approach. Do you want help from others or do you want to consider having others help you define a plan and create an approach. Some want help, others feel they can do it cheaper themselves. If this is you, you may be right.

Here is a way for you to think through your situation. It is true that architects, engineers, contractors and Energy Service Companies will charge for their services. Ask yourself if you believe their expertise can provide a better long-term value. The money you are saving by doing it yourself may be eaten up by substandard solutions and lost savings while you wait for projects to be completed.

Or there could be significant ideas or strategies that will provide savings that you haven’t learned about. A professional with significant experience may be able to help you achieve greater savings, more quickly that are more sustainable. Ask yourself these questions:

Energy Knowledge

Do you know how much energy your facilities consume?
Do you understand how and why energy is used in your facilities?
Are you familiar with the latest energy saving equipment, systems and strategies?
Do your energy saving ideas have many details that need to be evaluated and understood for proper implementation?

Systems and Equipment Knowledge

Do you have the ability to identify the real problems or determine the best solution?
Do you know what the issues are with your current equipment or systems?
Do you have the time and technical ability to investigate many products/solutions and determine which ones are the best?
Do you have the time and ability to put out an RFP and evaluate the proposals you get back?

Implementation Knowledge

Do you know how to manage the implementation of the solutions you decide on?
Does your staff have the time to install the equipment?
If it takes you longer to implement the solution how much will you lose in savings?
Are you comfortable managing contractors and vendors to make sure you are getting what you are paying for?
If they don’t do something correctly will you know?
What things will you hold your staff or the contractor accountable for? Schedule? Quality? Savings?

Operation Knowledge

Do you know how to maintain the solution appropriately?
Do you know how to operate it in the most efficient manner?
Will you know if it is not operating correctly or achieving the energy efficiency you expect?
If your bills don’t show the savings what will you do?

If you believe energy efficiency is important and are interested in having your district operate more efficiently, consider the accompanying Steps to Energy Efficiency. Whether you do them yourself or with a consultant, you can improve your situation. Each step builds on the preceding one to optimize your facilities into high-performance schools.

Steps to Energy Efficiency

What decisions will you make about energy efficiency? As this question arises in your organization, help educate others that what you do has a large impact on your overall financial success. Consult with outside professionals as appropriate, and continue doing all you can to improve the quality of education provided in the state of Missouri.

Should I Wait to Fix my Boiler?

May 22, 2017

old boiler

If an HVAC technician told you your furnace was old and needed to be replaced, even if it was currently running OK, would you replace it?

For most people, perhaps myself included, the answer is no! In my head I would think that my boiler maybe has another 1–2 years of life left. I would also think that if it did fail, I would call up my tech, he’d say “I told you so”. Then I’d pay a premium for an emergency install. But at least I’d think I got my money’s worth from that piece of equipment!

It’s not quite the same situation in a commercial building or in a school, but I still run across this scenario pretty often—even in facilities that can’t afford to lose a single day because of the lack of heating (or cooling).

Equipment failure can cause heartburn – from the increase in cost of an emergency installation to lost days of occupancy. Additionally, since during failures time isn’t an available commodity, one scenario that isn’t often considered is whether it would be best for the entire system to be replaced.

Waiting to replace equipment until it fails typically locks a facility to the existing system for another 25–30 years.

In buildings that have 50+ year old hot water pipes, does it make sense to install a new boiler when the pipes should also be replaced?

Does it make sense to replace a water cooled chiller when the entire system—from the cooling tower to the air handlers—also needs replacement?

Sometimes, the answer is yes, sometimes it’s maybe, sometimes it’s no. Before committing another 25–30 years to an existing HVAC system, understand there are many ways to provide for a clean, comfortable space.

Talk to your provider and explore your options before equipment fails.
