Advanced Low-Energy Laboratory Design, Commissioning, and Performance: The Dartmouth College Class of 1978 Life Sciences Building
David Madigan, P.E., LEED AP®, van Zelm Heywood & Shadford, Inc.
Bo Petersson, P.E., LEED AP, Cornerstone Commissioning
The Dartmouth College Class of 1978 Life Sciences Building is a LEED® Platinum research and teaching facility spanning approximately 170,000 square feet, completed in August 2011. The project was designed to achieve the highest levels of energy performance, utilizing a variety of innovative building system technologies. The presentation will provide an overview of the metrics-based approach to establishing goals for energy usage and the building systems utilized to achieve the exceptional energy performance. These systems include variable air volume chilled beams, enthalpy wheel heat recovery, Aircuity environmental monitoring and airflow reset, outside air preheat using heat rejected from interior laboratory spaces, displacement ventilation and radiant cooling for non-laboratory areas, condenser water heat recovery for domestic water preheat, and advanced lighting control with daylight dimming, among others.
The speakers will review the design challenges of integrating these advanced building system technologies, along with the commissioning process undertaken to ensure the systems perform properly. The speakers will also describe the challenges of bringing this complex facility on line and operational issues encountered during the first year of operation. The project includes extensive energy reporting capabilities. The speakers will review results of the first year of building energy performance against that predicted by the building energy model.

David Madigan is a principal of van Zelm Heywood & Shadford, Inc. of Farmington, Connecticut. van Zelm is a mechanical and electrical consulting engineering firm that specializes in many areas of design, including college and university, hospital/healthcare, pharmaceutical, public and private schools, and industrial facilities. Mr. Madigan is a graduate of Villanova University and holds an Masters of Science in energy engineering from the University of Colorado. He is a professional engineer registered in nine states. A LEED AP and frequent speaker on sustainable design, Mr. Madigan has worked on numerous projects with sustainable design objectives; of note is Mr. Madigan's experience in design and planning of high efficiency, sustainable laboratory facilities and the development and implementation of campus energy master plans. Mr. Madigan has worked on more than 20 LEED certified projects and has been responsible for the mechanical systems design for several major laboratory projects that have achieved LEED Gold or Platinum certification.
Bo Petersson is a registered professional engineer and is the director of engineering services of Cornerstone Commissioning of Boxford, Massachusetts. The firm is focused on commissioning laboratory facilities, but has diversified into many other types of buildings, many of which are for critical environments. Prior to working for Cornerstone Commissioning, Mr. Petersson worked for 14 years as the Dartmouth College campus mechanical engineer. In this role, he was involved in many cutting-edge projects, many of them heavily focused on energy-efficient operation. Mr. Petersson's background in facilities operations has resulted in a company-wide hands-on approach to commissioning, with a strong emphasis on fine-tuning of control system sequences. He has spoken at several industry meetings on commissioning, energy-efficient buildings, and chilled water operation.
