Hospital Considers Life Cycle in Electrical System Design
Parkland Hospital in Dallas, Texas, is employing life cycle planning as an integral part of its new hospital construction, according to a paper from Legrand. Scheduled to open in the spring of 2015, the 2.1-million-sq-foot facility will house 575 miles of conduit, more than 32,000 light fixtures and more than 42,000 data outlets.
To achieve ambitious goals in electrical system performance, the Parkland project team employed modeling as a vital part of its life cycle planning, says the Legrand paper “The New Dynamic of High Performance Buildings: Advanced Electrical Design Principles in Practice.”
The Parkland team moved beyond computerized modeling and constructed extensive full-scale mockups to test design concepts, usability and make product and vendor selections.
To facilitate the electrical systems design at Parkland, 10,000 square feet of patient care and surgical areas were modeled. One design nuance identified during this phase was the need to calibrate the controls to work efficiently with every light source. Because LED fixture drivers respond differently to standard low voltage control signaling, control of light and energy usage can fluctuate up to 20 percent if using an uncalibrated control system. By commissioning the controls for each fixture type to ensure linear performance, centralized commands will accurately deliver the desired light conditions and energy savings.
