This design environment keeps moving, but the performance and cost pressures remain. Weigh air-side and water-side economizers carefully: not just one or the other, but the options within each approach.
Modern data centers are evaluated not just on reliability but also on the efficiency of the cooling plant that supports them, so the cost to cool data center space is a key issue that must be addressed during design and system selection.
Last month, this column acknowledged the fact that some projects do not have written Owner’s Project Requirements (OPR) documents for the commissioning professional to reference.
When a large national retailer wanted to reduce energy costs at one of its new distribution centers in Topeka, KS, it turned to Cambridge Engineering and its High Temperature Heating & Ventilation (HTHV) technology to help them out.
Energy recovery, sensors, and smart deployment of other options can let a system clear the psychrometric hurdle of designing for high outdoor air requirement and high moisture levels.
Dedicated outdoor air systems (DOAS) have been available for over 20 years, with the primary benefit being the ability to decouple outdoor air tempering from conditioned space thermal loads that can be handled by separate, secondary systems.
Understand the differences that can exist among various options so you can avoid a design that inadvertently paints the owner (and yourself) into a corner.

Designing a VRF system for competitive bid is challenging due to each manufacturer’s unique implementation of the VRF system technology.
You can create a tailored algorithm or you can use Hartman Loop technology. You can implement better temperature controls for the chilled water supply or the condenser water. Keep your eye on the long term and pick your weapon.
