There are many items that show up again and again in design and construction practices that guarantee low performance, waste energy, and drive building operators and occupants crazy. 

This presentation shares information, perspective, and lessons learned in the “trenches” by the commissioning authorities and building operating staff while bringing buildings on-line and beginning operation.

This presentation focusses on hydronic systems and explain why several design elements either live up to or fall short of their promised glory, and identifies several common problems that sabotage the proper operation and potential savings.

Learning Objectives

  • ·         Identify common reasons buildings fail to operate properly and efficiently
  • ·         Be able to Identify Hydronic System’s largest energy users.
  • ·         Identify at least 5 design and control strategies to meet ASHRAE 90.1 energy usage requirements.
  • o   Save 20 -30% energy (above High-Efficiency equipment).
  • o   Or waste up to 50% if they are missed.
  • ·         Recognize drawing details that make the difference between a functioning system and a poorly functioning system.
  • o   “Key” coordination items that are commonly missed, resulting in costly change orders.
  • o   Design details needed to verify functionality and energy performance.

Speaker Bio

Todd L Rindlisbaker, is a Senior Commissioning Authority for Facility Dynamics Engineering Corp. He received his degree in Mechanical Engineering from Utah State University 1993, and is a registered professional engineer. He served on the Utah ASHRAE Chapter Board of Governors and as the ASHRAE liaison to the Utah Engineers Council. He also served for six years as a member of the Board of Directors for the Southwest chapter of the Building Commissioning Association and was elected to offices of President, Vice President, and treasurer. He also served on the BCA’s task force which published the Best Practices for New Building Commissioning Standard.

Todd has worked in as a mechanical HVAC and Plumbing design engineer specializing in large hydronic systems, central plants and building management control systems. He was been commissioning new and existing buildings since 2002. He consults with building owners, design teams, and contractors to build sustainable, energy efficient, functional buildings that cost less to build and operate so they attract more business, make more profits and have buildings that will last a lifetime.

He has been training owners, contractors, design professionals, and other commissioning authorities in various sustainable design topics such as LEED building rating systems, the Integrated Project Delivery Process, and Commissioning Practices. He has lectured at the Salt Lake City Sustainable Building Conference, Western conference of the National Association of State Facility Administrators, National Conference on Building Commissioning, Rocky Mountain APPA conference, University of Utah Facility Managers, many ASHRAE chapters and many private organizations. Todd has been honing his presentation skills for many years as an Associate member of the Rocky Mountain Chapter of the National Speakers Association.

Mr. Rindlisbaker is a member of the Utah Engineer's Council (UEC), the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE), U.S. Green Build Council (USGBC), and the Building Commissioning Association (BCA). His is a recipient of the 2007 Valley Forward Award of Merit for Buildings and Structures-Industrial and Public Works—East Valley Bus Operations and Maintenance Facility, Tempe, AZ (provided commissioning), the Intermountain Electrical Association Electrical Industry Best Projects 2007 Award for Renovations/Restorations - Utah State Capitol Restoration and Seismic Upgrade, Salt Lake City, UT, and the 2008 ACEC-UT Engineering Excellence Grand Award – Utah State Capital Restoration and Seismic Upgrade, Salt Lake City, UT.
