This Isn’t Just About Energy…
This is About You
ACHIEVING!LEADING!SUCCEEDING!
Super Bowl Equivalent- Is your Goal to get a Wild Card Playoff spot?- Is your Goal to avoid the Wild Card playoff and play the second round at home? (Like the Panthers and Seahawks) - Is your Goal to win a Division Title?- Is your Goal to get to the Super Bowl?
Is it your Goal before the season started to win the Super Bowl???
Good is the Enemy of Great

Why Should You Establish a Baseline or Benchmark? You Are
HERE
Can You Imagine a Ruler With No Markings?
Exercise: How do you get to where you are Going?
-3 Different Routes- Time Spent- Distance Traveled- Fuel Used- Which is the most efficient?
Exercise: What Tools Do We Use?
- Map- GPS- App on Smart Phone- Experience- Which is the most efficient?

Reduced Operating Usage (Hours)
Energy Savings is based on two main factors:
Baseline=Benchmark?What is it and why is it helpful?
Technical: (Pertaining to Energy)Before performing a retrofit, savings must be determined by comparing energy use before and after. The proper documentation of the pre-retrofit or baseline conditions is critical. If this information is not documented, it is lost and cannot be determined after installation.
Energy Savings is based on two main factors:
Improved Performance (Usage) Reduced Operating Usage (Hours)
Baseline or Benchmark:
It is a measurement that is taken to gain a full understanding of what is being used or spent during a certain period of time in the past. It can be measured against to see if there is any positive or negative change, or if things stay the same once changes have been made.

Class from SchoolDude University 2013:Advance It - How to Create In-House Energy Management-Bob Cervi, Eanes ISD
Activity: Losing Weight
- Eat Healthier Foods/Less Candy- Drink More Water/Less Soda- Exercise More/Stay Active- Portion Control- Get More Sleep
235 Lbs
200 Lbs
- Maintaining the Status Quo- Fad Diets- New Year’s Resolutions- “Diet” Foods
I have to track how much I am eating and be disciplined!

Activity: Tracking Data
Tracking the data gives me visibility, accountability, and motivation. I can access it anytime and track progress Make adjustments when needed
Activity: Using Energy Efficiently
- Change Usage Behaviors- Adjust HVAC Set Points- Conduct an Energy Audit- Tune Building Automation System- Retrofits and Upgrades
ASHRAE cites the National Average for K-12 Schools is 60 KBTU/SF/Yr. (Site EUI)*
90 KBTU
50 KBTU
- Maintaining the Status Quo- New Equipment Will Fix Everything!- Just pay the bills
I have to track how much energy I am using and be disciplined!
How do I Know which Buildings Need Help?Do you want to Save Money and Be Better Stewards?
- This does not happen overnight.
- This will be measured in months, but more likely, years.
- This is not easy.
-This will take a lot of work.
-This will involve a lot of people at your educational organization.
- This will help your educational organization save time, money, and resources.
- The students, faculty and staff, and other stakeholders can make a difference and see the results.
- This IS important.
Step One: Put the Use and Cost Data into UtilityDirect
This part is painful and tedious, but has to be done. My daughter, Olivia, LOVES doing data entry in UtilityDirect.
DATA ENTRY IS FUN!!!!
No child labor laws were broken making this meme.
Utility Bill Automation ServiceEntire Educational Organization
- Map Actual Bill Accounts with Bill Accounts in UtilityDirect.- Service Looks for new Bills on an ongoing basis- Bills get entered into UtilityDirect automatically- Error checks are performed and communicated
Two Types of Benchmarking
Entire Educational Organization
- What was used overall?- What was spent overall?- Was there improvement or regression?- What were the factors
Individual Buildings
-What was used for this Building?- What was spent for this Building?- Was there improvement or regression for this Building?- What were the factors for this Building
Overall
Specific
How do I Benchmark?
-Source EUI:(Source Energy Use Intensity) The total amount of all the raw fuel required to operate your property, including losses that take place during generation, transmission, and distribution of the energy divided by a building’s square footage.
What is EUI and KBTU?
-Site EUI: (Site Energy Use Intensity) Site Energy is the amount of all the energy your property consumes on-site, as reported on your utility bills divided by a building’s square footage. Use site energy to understand how the energy use for an individual property has changed over time.
-KBTU/Square Foot: This is the same as Energy Use Intensity and is one thousand British Thermal Units, divided by a Building’s square footage.
How do I Benchmark?
-Look at Site EUI or KBTU/SF-Measure each Major Utility Individually
(Electric, Natural Gas, Water)
-Choose a Baseline Year to Start. Do some research to figure out one that will work.
-One Year might be a lot better or a lot worse If you have the data in UtilityDirect, it will be a lot easier.
-Set a realistic goal: The USDOE says we can save 10% if we are just aware of what we are spending and using. Set a higher goal, maybe 20%.
Overall
Step 2: Pick a Building to Focus on
High Schools Elementary Schools
VS- Larger Size/More Students- More Complicated Spaces- Different Operating Hours- More Technology Integrated
- Smaller Size/Less Students- More Simplified Spaces- Concrete Operating Hours- Less Technology Integrated
Step 2: Pick a Building to Focus on
- Multiple Uses- More Complicated Spaces- Different Operating Hours- More Technology Integrated- Cannot be Energy Star Rated
- Can Be Energy Star Rated- More Simplified Spaces- Concrete Operating Hours- Single Purpose

How do I Know which Buildings Need Help?
Rank ThemI would:
-Break them into their different Uses (HS/MS/ES Admin)-Make sure they have complete data for the last 3 FY-Then, Look at their KBTU/ SF for the Last 3 Years- One Step Further: Get their Energy Star Rating- Who can improve the most? This will tell you.- If they have a qualifying Energy Star Score, why would I spend the resources to make it even more energy efficient?
The Buildings with the Lowest Score give you the most opportunity for savings. Prioritize them, but keep an eye on the top performers and average ones. They can be addressed last. Stop the Bleeding with the bad ones.
How do I Know which Buildings Need Help?
The Buildings with the lowest Energy Star Score give you the most opportunity for savings. Prioritize them, but keep an eye on the top performers and average ones. They can be addressed last. Stop the bleeding with the bad ones.
How do I Know which Buildings Need Help?Then, I would:
- Make Behavioral Improvements First (Minimal Investment of Resources)- Lights and HVAC off when unoccupied.- Personal Appliances minimized.- Technology Assets off when not being used at the end of each day.

How do I Know which Buildings Need Help?Then, I would:
Look at Simple Fixes that are Relatively Inexpensive
- Is the Building Sealed Properly? (Windows and Doors)- Are the Set Points Optimized and are the Building Automation
Controls tuned properly?- Are we changing HVAC Filters on a regular basis?- Tying Facility Scheduling to BAS through SchoolDude FSD and FSA.
Preventive MaintenancePay me now or pay me later.
How do I Know which Buildings Need Help?Then, I would:
- Examine making larger investments in improving major building systems- Efficient Lighting (T8s/T5s/LED) Retrofit- Updated HVAC Systems that are more efficient than existing ones.- Occupancy Sensors/Computer Power Mgmt. Systems- New Roof/Glazings/Overall Envelope Improvements.
- ASHRAE Level I, II, and III Building Audits- Performance Contracting
Major Retrofits andCapital Improvements
Step 3: Evaluate the Results
How do I Know which Buildings Need Help?
- Run Reports and compare where we started with where we are now.
-Did we improve? Great! How much? Tell everyone what you did, how much you improved, and then move on to the next opportunity.
-Did we stay the same? Is there anything else we can do differently? Is there something we forgot.
- Did we get worse? Time to consult Experts
-What you do for one building may not work for another. That is why you have to look at each one individually.

Reports
34
Building Total UseThis report generates a bar graph of total use for a utility type for a single building, multiple buildings or all buildings. The comparison can be made for a single year or multiple years.
Reports
35
Global Building Use Summary (No Graph By Default)This report shows use by month by utility type for each building. Filter by single or multiple building types, utility types, months and years. It generates a pivot table like the one below by default and the user can insert a pivot graph if it is needed based on the raw data.
Reports
36
Global Building Use By Utility (No Graph By Default)This report shows use for each building by single or multiple utility types and years. Also filters by building type and shows total use by utility type for all buildings.
*By default, the report generates the table to the right. You can insert a pivot chart and construct a graph like the one above.
Reports
37
Global Use Per Square FootThis report shows ALL Buildings in the account on a use per area basis. Filter by single or multiple building types, utility types, months, and years. Also filter on areas greater than a specified number.
Reports
38
KBTU Report (No Graph By Default)This report shows the total KBTU, of the gas and electric accounts, as well as the area for multiple buildings. The report can reflect a single month for a single year or multiple months for multiple years.
Reports
39
KBTU Per Sq. Ft.This report generates a bar graph showing the usage per square foot, in KBTU, of all accounts that are measured by *units of energy for multiple buildings. The report can reflect a single month for a given year or every month for that year.*Accounts that are measured in units of energy like Electric, Natural Gas, and Fuel Oil are converted to a uniform unit of measure called KBTU. Non-energy accounts like Water, Sewer, and Trash cannot be converted to KBTU. 1 KBTU= 1,000 British Thermal Units.
Reports
40
Energy Efficiency Report (No Graph By Default)This report shows the KBTU of the gas and electric accounts per square foot, per total degree days as well as the area for a single or multiple buildings. The report can reflect a single month for a single year or multiple months for multiple years. It does not include a graph but the user can insert one by using the Pivot Graph tool in Excel.
Reports
41
Weather NormalizationThe Weather Normalization Report is designed to give users only a general estimate of the effect of weather on utility consumption from year to year and a general estimate of any possible utility usage avoided from year to year.
Reports
42
Account Details By Building (No Graph By Default) This report is the “Swiss Army Knife” report in UtilityDirect. It shows start/end dates, use, demand, and cost for each bill for each account, to name a few fields. If you cannot find a report that will give you what you are looking for, the Account Details By Building report is a comprehensive report that will help you build a very detailed table or graph. It can only be run for one year at a time.
