Weber Refrigeration Heating and Air Conditioning
In the mid 1970s, our founder and CEO Mike Weber was trained by Honeywell Controls to perform Energy Audits and design Energy Savings solutions for our customers. Since then we have saved our customers TENS OF MILLIONS of dollars through our Energy Audit Services and Energy Management Services. While we save our customers energy every day through engineering new and more energy efficient systems for their homes and business, Energy Audits is yet another step.
When we enter into an Energy Audit contract with our customers we begin an investigation to determine the following:
1. Where are their energy dollars going?
a. We run a computerized heat load/heat gain calculation to
determine the HVAC requirements.
b. We evaluate all existing HVAC&R equipment for it's rated efficiency and it's current operating efficiency.
c. We evaluate the entire building for large non HVAC&R uses that may have opportunity for change.
d. We evaluate the building envelope (windows, doors, insulation, roof) for problem areas or areas of excess heat loss or heat gain.
2. What are the opportunities for savings?
We then list all of the opportunities for savings and begin to evaluate the practicality of each project individually. That is where step 3 through 5 come in.
3. What are the savings of implementing the changes?
We gather 3 years of utility usages and charges. We then enter these into a spreadsheet with other pertinent data, such as the heating/cooling degree days, specific building design, any peculiarities that would affect the building balance point, and other factors to determine the cost of heating and cooling and the fixed costs of lighting and other uses.
4. What is the cost of implementing the changes?
5. What is the Return On Investment (ROI) for making those changes? In most cases we present our customers with a list of several different project opportunities. We then provide them with the costs and expected or guaranteed energy savings. In addition to Energy Savings, some projects also offer Maintenance and Repair Cost Savings. The ROI is simply the ratio of Total Savings over Cost. Most of our customers find that the ROI is a very valuable tool in prioritizing the projects.
USD 374 in Sublette is one of our most recent Energy Audit Projects. In addition to many other tasks, here we were able to help them get a 150' tall Wind Generator going. This generator had not ran for 7 years due to PLC computer programming problems. We repaired the code and they now have the potential to generate $68,000.00 per year of their own electricity.
Dodge City Medical Center was one of our first Energy Audits. Here we identified and corrected many opportunities and saved them over 40% on their gas bills.
Among the most significant of our Energy Audit Projects was USD 466 of Scott City, KS. Here we identified and executed multiple upgrades in every district owned building including: lighting upgrades, window and insulation upgrades, HVAC redesign and recontrol, boiler replacement, heat pump recirculating water loop temperature optimization managed by computer algorithms for maximum COP and EER, air compressor management, time of day programming, peak demand management and many other varied small projects. This project was guaranteed to save the district $27,655.00 per year in energy and far exceeded the guarantee (up to $36,008.00 per year), without sacrificing comfort. This savings represented a reduction in their heating bill of over 45%, as well as very significant electrical usage and demand charge savings.
