Building’s Current Water Design
High efficiency fixtures that are 40% more efficient than standard plumbing have been implemented
A 19,000-gallon storage tank that collects rainwater is used for bathrooms and irrigation
Ir r igat ion Usage During the winter the irrigation system is shut-off (November - April) When the system is on, the majority of the incoming water goes towards irrigation (Predicted to be about 30%)
Ideally, after the first 3 years, the plants will be established enough to be self sufficient This will reduce the irrigation usage for a sustainable building
Meter ing the Usage
Typically, the city charges for: Water from the city
Sewer wastewater
Assumed that all city water goes to sewer
Problems: Not all incoming water goes to sewer rainwater that goes to sewer isn’t metered
High Efficiency Fixtures
Sinks: 0.5 gpm Urinals: 0.128 gal/flush Toilets: 1.25 gal/flush
Net Water Usage Over Time
Improvements: Ir r igat ion Controller
The current irrigation controller is manually changed
Should be programmed to automatically irrigate
Hook up the “Calsense Command Center” : Linked to internet for weather
Elect r icity Usage And The Solar Array
Solar Array Product ion (February)
The Buildings recorded data
1016 kWh produced Savings: $91.87
Our Prediction
4656 kWh produced Savings: $421
PUD
2480 kWh produced Savings: $224.19
Total Capacity: 74.7kW
Maximum Possible Energy: 50,198kWh
Total Building Consumption: 76,580 kWh
Solar Array Product ion
The Buildings Performance
Current Temperature Controller
Reactive System Requires Large Temperature band (can be uncomfortable) Can waste energy by heating and cooling unnecessarily
Neural Network
Accuracy of Neural Network Model
How This Can Improve The Heat ing System
By being able to predict the temperatures of a given room we can fix the issues with the current temperature control system.
Reactive System Requires Large Temperature band Can waste energy by heating and cooling unnecessarily
Future Improvements to Neural Network
Improvements to Neural Network:
Switch to using a recurrent LSTM network Allow Neural Network to control heating systems
Improvements on Data Collection:
Collect data over a longer period of time Occupancy data Heating systems More accurate temperature data

APWA Student Outreach Network
W hy get involved with Student Outr each
APWA involvement Networking Preparing the next generation for the workforce How does my organization benefit? Develop an internship program within your organization Fill positions with devoted students from your chapter Volunteer opportunities for students at your organization’s events
Other possibilities; committee involvement, recognition for other programs, etc.
APWA Student Outreach Network
H ow to cr eate your own Student C hapter
Join the Student Outreach Network
Who needs to be invested You Your boss Faculty Advisor
Host a Kick-off event at the school
Create a meeting schedule
Develop a constitution
Be engaged and available
The trai l to creating a Student Chapter has already been blazed!
