Sorell has over 20 years
of experience as an HVAC design engineer, with at least half of those years
involved with design and commissioning of HVAC systems for critical facilities.
As Syska’s National CFD expert, he performs CFD analyses to compare and
evaluate various system design options for high density equipment cooling
configurations. In addition, he researches how to quantify the environmental
conditions inside as well as outside cabinets as a function of cabinet configuration
and cabinet load. He is a member of ASHRAE TC-9 “Mission Critical Facilities,
Technology Spaces, & Electronic Equipment,” and is a member of Syska’s
Critical Facilities Technical Leadership Committee dedicated to improved
engineering design practices.
This thorough article provides an overview contrasting
traditional design elements with approaches not usually selected for mission
critical facilities. From ventilation to piping to chiller configuration to
water usage, nothing is taken for granted - except the need for reliability and
the desire to increase efficiency. The authors, from Syska Hennessy Group, also
discuss their firm’s Green Critical Facilities Committee and how it works
within the framework of the conventional process.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
