Henny van Lambalgen

Henny is the founding principal of Quest Energy Group and has over 20 years experience in the energy industry with a primary focus on building energy consumption. He is an expert in the use of state-of-the-art computer programs such as DOE2 for determining the energy and economic impacts of alternative building architectural features and heating, ventilating, and air conditioning systems. Henny has used this expertise to provide modeling assistance to architects, engineers and owners in the design of energy efficient buildings as well as to demonstrate compliance with energy codes such as ASHRAE 90.1 and California’s Title 24.  Henny compliments his computer skills with  considerable hands-on experience with building systems. He has been involved on a number of end-use monitoring projects ranging from performance testing of unitary package equipment to large central plants.  At Quest, Henny focuses on building simulation/LEED energy analysis, monitoring and verification, and investment grade audits.

Additionally, Henny has applied his expertise to the support and development of utility efficiency programs. These range from residential programs such as Arizona Public Service’s Good Cents program to large commercial programs such as Southern California Edison’s (SCE’s) Unit Energy Savings (UES) project. Mr. van Lambalgen was the lead engineer in developing the 1994 UES results, a task that encompassed the simulation and processing of over 10,000 computer runs encompassing 13 building sectors in eight California climate regions.
