  • Project Overview

    Chaffey College had efficiency problems with boilers and chillers spread throughout their campus. After consultations, the college decided to increase the efficiency of its utility services with a new central plant and underground piping distribution system. We provided engineering services, construction documents, cost estimates and construction administration from inception to the post-warranty period. The distribution portion of the project included approximately six miles of underground piping that connected 18 buildings served by the central plant.

  • Solution

    The new 1,800-ton chiller plant was designed to provide cooling to campus buildings while the new 9 MMBtu boiler plant was designed for maximum efficiency while minimizing output of end products subject to regulations by the South Coast Air Quality Management District (SCAQMD). We also built-in some flexibility for new telecommunications, as well as electrical and gas infrastructure for existing and future buildings on campus. The new central plant saved Chaffey over $500,000 in operating costs during the first three years of operation. The design also won a 2007 Engineering Excellence Merit Award from Consulting Engineers and Land Surveyors of California (CELSOC).

Kaiser Permanente Baldwin Park Medical Center is set to undertake an estimated $300 million infrastructure upgrade project. As part of the Design-Assist team, we’re providing our mechanical and plumbing design expertise for this replace and rebuild effort at the hospital, central utility plant building, and medical office building. Our team is working with the project general contractor and subcontractors in a “big room” setting, regularly coordinating with Kaiser’s Facilities Strategy, Planning and Design (FSP&D) Department and the project team to ensure design functions as intended.

We’re replacing existing air handling units, chillers, heat exchangers, cooling towers, humidifiers, fan coil units, exhaust fans, and controls. In the first phase, we are providing design options which will include sustainable design for each system to lower the building Energy Use Intensity (EUI) from 230 to 160. The strategies will include heat recover chiller design to save heat energy on the domestic hot water system, convert constant air volume distribution to variable air volume system, design air handlers with separate cold and hot decks to optimize economizer mode to name just a few of our improvements. The new Direct Digital Control (DDC) system will optimize the building’s energy use and will automate the entire HVAC and plumbing systems to minimize maintenance. This project received a CEC grant for its sustainable design to de-carbonize a large healthcare facility.
