Upgrade to Energy-Efficient Infrastructure - Take Some Action

The Department of Energy reports that schools can save up to 30% annually on their energy bills by replacing inefficient boilers, lighting, and other systems with more energy-efficient alternatives. Students can also benefit from improvements in infrastructure. For example, upgrading HVAC components can not only make your building more energy efficient, but can increase Indoor Air Quality, so students are breathing cleaner air. Other building improvements are even linked to more success learning. For example, the Department of Energy reports that studies show a connection between the use of daylighting and better student performance. The California Board of Energy Efficiency recently conducted a study of 21,000 students that showed an increase of 15% to 26% on test scores for classrooms that had daylighting.

Before considering major energy efficiency improvements…
Before considering upgrading your school’s HVAC system or undergoing major renovations, make sure you’ve conserved energy in every possible way using our no-cost/low-cost conservation tips. The Conservation Tips include information on changing lights and buying Energy Star Appliances, which are some of the most cost-effective ways you can make energy efficiency improvements.

How to decide what improvements to make?
In order to decide what improvements you should make to your building, you should follow two steps:
  1. Find out where the low-hanging fruits are, projects that will be easiest, cheapest, and least risky.

  2. Compare the cost of each potential project with how much energy each is expected to save and what local or federal financial incentives may be available.
The Department of Energy explains that many school districts focus on their most inefficient systems first, then use the energy savings from those projects to pay for more improvements later.

To find out which systems are the most energy inefficient in your school, you should conduct an energy audit. You may have a couple refrigerators that are sucking up three times the amount of energy they are supposed to because they are broken. Or, you may find that your heat loss from the building exceeds the cost of electricity improvements you could make. The only way to discover this information is to examine the whole building’s energy use components and patterns through an audit. Some audits even spell out potential solutions for you to consider. Energy Star’s Target Finder will then help you set a realistic energy improvement target.

But, once you’ve decided what areas of the building need improvements, you still have to weigh the financial benefits of each potential solution. Consider using the Energy Star Portfolio Manager to help your school district focus on the most beneficial improvements and weigh the options of potential renovations. It also helps you track the progress of improvement projects after completion. Portfolio Manager synthesizes information from every building in the school district by tracking energy and water consumption and contracts, overall building performance, future investment needs, LEED certification requirements, and mortgage, sale, and lease transactions. Best of all, the program helps you apply for an Energy Star label for one of your buildings so that you can gain recognition from the EPA for your energy efficiency efforts. Your buildings’ statistical data can be compared to other K-12 buildings across the United States, helping you gauge your progress.

Also, check here to see if there are any local businesses or organizations in your state offering help for identifying, weighing, and implementing improvements. For example, the Bright Schools Program run by the California Energy Commission offers help conducting energy audits, reviewing existing proposals, assisting with contractor selection, and reviewing equipment bid specifications and commissioning plans. Also, check Energy Star’s searchable database of Service & Product Providers (SPPs).

We want to make improvements, but where do we get the money?
Energy Star offers some helpful guides explaining how to find funding for your project within the framework of your existing budget.

Also, take advantage of energy efficiency grants and tax incentives that may be available to you. The Database of State Incentives for Renewables and Efficiency lists the major funding opportunities in your state. The DOE’s Tax Incentives for Energy Efficiency offers federal tax incentives. This site also includes software to help you calculate precisely how much money you would save through various tax incentives based on your building and your specific project.

Performance Contracting helps take the risk out of the decision of what to upgrade and how the investment will turn out
Many schools have benefited greatly from using “performance contracting” for anything from upgrading the building envelope to replacing heating system components. “Performance contracting” for energy efficiency is when a company comes into the school and focuses on conserving energy in a program to reduce energy costs. A certified performance contractor (known as an ESCO) takes on the technical and financial aspects of an energy efficiency project and assumes the financial risks associated with the project because they guarantee the energy savings. To find out more about how an ESCO can help finance your energy project, click here. There are many certified ESCOs. Check with your contractors to see if one of them is a certified ESCO. For more information about how to use an ESCO in your school, read the Guide for Performance Contracting in Schools by the DOE. And to see how other schools have already benefited, check out Energy Performance Contract Case Studies by Jessica Lefevre of the DOE.

What are some upgrades we should consider?
Whether you are just replacing a few basic appliances for more energy efficient ones or considering more extensive upgrades like the ones below, make sure you buy Energy Star Qualified Products. They meet rigorous government efficiency guidelines and are available in almost every major product line, including: air-conditioning units, central AC, furnaces, boilers, programmable thermostats, vent fans, and even windows, doors, and skylights. Furthermore, Energy Star’s Purchasing & Procurement Tips can help you decide exactly which model to buy.

After improvements, good operations and maintenance practices keep the savings coming
After you make conservation improvements, keep the efficiency benefits going through good operations and maintenance practices. For more on operations and maintenance programs, check out this guide from EnergySmart Schools. Some of the information is geared toward green buildings built from the ground up (which are called “EnergySmart” schools here), but many of the principles can be applied to existing buildings. The Department of Energy also offers this operations and maintenance page geared toward commercial buildings.

Buildings in many states have to follow the ASHRAE and IESNA energy code by statute. If your state uses these, you may have to meet certain requirements when undergoing renovation projects or upgrades. Some states use the newest 2007 version, while others use an older one or their own, and some don’t follow any at all. The 90.1 code is the most popular. The code includes mandatory requirements that differ for the size and type of the building. However, it generally includes minimizing the energy loss through transmission lines, documenting electrical components in the building, meeting lighting standards for new construction, additions, or lighting replacement projects, and meeting a certain maximum goal of the amount of electricity consumed for lightning needs. Specifics include things like the number of light switches in a certain area, a requirement of occupancy sensors in other areas, and even requirements for automatic lighting shut-offs set to a timer for large buildings. Beyond mandatory requirements, the energy code also includes prescriptive requirements for lighting and power use. Standard and compliance tools for buildings that have to meet these requirements are available here.
