In my May 2016 article, “The Radiant Roads to School Design,” I was in the middle of designing a building with a radiant heated and cooled slab with DOAS/openable windows for ventilation for the College of Continuing and Professional Education (CCPE) at CSU Long Beach (CSULB).

Optimizing Centrifugal Chiller Systems

Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned.

Finding the holy grail of centrifugal chiller optimization for all operating conditions is hard, if not impossible. This article will talk about the requirements of most chiller systems and means of control for condenser optimization.

Match Game: Boiler Types And Loads

In which the author explores the specific strengths and attributes of various boiler types, along with pumping options and other system factors. The goal: To help you intelligently align your project’s equipment choices with its particular load, meeting expectations while avoiding Delta T headaches.

Engineers face multiple options for providing hydronic heat, along with additional decisions regarding whether that design should also serve other components such as domestic hot water.

Assessing The Radiant Road To School Design

The Radiant Roads To School Design

Leaning on experience and data from various K-12 cities and projects, the authors pursue 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.

As an engineer there are two choices — improve the “norm” or forge ahead with something new or borrowed from previous generations.

Renewable energy sources are becoming more commonly incorporated by utilities. Unlike conventional generated power sources, renewables are intermittent and variable by their very nature. While utility and grid operators are integrating renewable energy into their systems through power management experiences, municipalities and commercial/industrial applications are turning toward Distributed Energy Resources (DER) to augment or replace utility provided power.
