Engineers retrofitting non-air conditioned schools to variable refrigerant flow (VRF) the last few years have relied on centralized packaged DOAS to comply with ASHRAE 62.1 outdoor air standards.

With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground-source heat pump (GSHP) system.

Clark County Public Schools in Kentucky has gained notoriety for its sustainable school designs.

This month’s B2B will focus an existing campus administration building renovation.

This past May I wrote in the Back2Basics column about the design intent of a small city school system that chose to invest in an annual contract for a temporary air-cooled chiller for special events and emergency crisis shelter center.

This month’s B2B will focus on a new 12-classroom building addition, each room with its own closed loop ground source heat pump (GSHP) unit.

This month’s Facility File will focus on the B2B June test for an HVAC application on a college campus with a building program to construct a new 12-classroom facility. The project delivery method is integrated project delivery (IPD).

A higher education campus presents an extensive amount of variables that can drastically impact the requirements of the indoor environment.
