Tech Session - 5:00 pm - Taking the ‘garbage’ out of energy modeling through calibration.  By Benjamin Skelton.

Dinner - 6:15 pm

Main Presentation - 7:00 pm - Walgreens Net-Zero Store.  A Case Study.  By Benjamin Skelton.

Tech Session Highlights

Garbage in, garbage out is a common saying when discussing building energy modeling. When creating a forward energy model during building design, a lot of assumptions are made to determine annual energy consumption. Only a few brave modelers have the confidence to guarantee those results. Calibrated energy modeling uses measurement and verification data to answer unknowns and provide a tool for performing deep analysis on building energy performance potential. This technical session reviews the what, why and how of calibrated energy modeling and gives examples from models built to study high rise enclosure systems and a net-zero energy project.

 

Main Presentation Highlights

The Walgreens Company, a global retail pharmacy brand with over 8,000 stores, set out with a vision to create a showcase for innovative, sustainable, high-performance design at a retail location without altering the operational characteristics of the building in order to make it as highly-scalable as possible, and to share this information with the sustainability, architecture, and retail communities in a completely transparent fashion as a means of encouraging the adoption of green building practices wherever reasonably feasible.

This case study sets out to tell the story of how the Walgreens Net-Zero Energy Store at 635 N. Chicago in Evanston, Illinois, was designed to accomplish this vision through state-of-the art design techniques, high-efficiency equipment, advanced control strategies and superior indoor environmental quality, and how the measurement and verification process is using calibrated energy modeling to track performance.

The Store Has the Following Sustainable Strategies: 

  1. Elimination of non-critical plug loads (under shelf lighting, coolers by checkout counters)
  2. Right-sizing of HVAC systems
  3. LED light fixtures
  4. Daylight dimming
  5. Automated shade controls
  6. Light louvers
  7. Dedicated outdoor air system with demand control ventilation
  8. Natural ventilation
  9. Geo-exchange field coupled with a cascading CO2 refrigeration compressor system that controls the freezer, cooler and provides heating, air conditioning, and service water heating to the entire store
  10. Energy Management System

The project has been designed to achieve Net-Zero Energy and been in operation for over two years with documented net-zero performance. It has been awarded ASHRAE Engineering Award of Excellence 1st Place New Construction at the Illinois Chapter, Region VI and International Society. The project is LEED Platinum Certification, Green Globes Certified, Green Globes, US EPA Green Chill Platinum and in consideration for Living Building Challenge.

President, Cyclone Energy Group, Chicago

BS Mechanical Engineering, Iowa State University, Ames, Iowa

Skelton is the founder and president of Cyclone Energy Group, a Chicago-based building performance consulting firm. As a consulting engineer, Skelton specializes in energy efficient and sustainable buildings, and is recognized as an expert in building energy simulation, building commissioning, and retro commissioning. He has worked on a wide variety of buildings and projects that include ENERGY STAR certification, U.S. Green Building Council LEED certification, and net-zero energy buildings. Skelton is very involved with ASHRAE at the local, regional, and society levels. Through his technical committee activities, he has helped implement the first-ever standard for commissioning (ASHRAE Standard 202).

He enjoys spending time outside through running, biking, hiking, and camping. Competitive running has long been his favorite activity. He ran several marathons including Chicago, Boston, and Paris and competed twice in the Ironman Wisconsin triathlon. Most of Skelton’s time out of the office is spent with his family. He enjoys walking in the park with his newborn baby daughter and building LEGOs with his 5-year-old son.
