DEA Federal Building – Mechanical, Electrical, Plumbing Systems Design, Los Angeles, CA

Development One was responsible for the replacement of the HVAC system at the DEA Federal Building in Los Angeles. The existing HVAC system in the basement was inefficient, required costly annual maintenance, and was unable to provide adequate comfort to the building occupants. The project objective was to replace the existing system with two air cooled rooftop units. Development One completed this project in three phases:

Phase 1: Equipment ReplacementDEA

  • A 55 ton and 60 ton roof unit were installed and provided with power. New circuit breakers, feeder circuits, and switch boards were installed.
  • In order to minimize downtime, all roof ductwork and penetrations were done prior to the demolition of the existing system.
  • Energy meters were installed on all major HVAC equipment.

Phase 2: Air Distribution System

  • Existing pneumatic controls were replaced with a Building Automation System (BAS). The BAS will reduce maintenance costs, allow comfort issues in the building to be solved effectively and efficiently, and the response to system loads will occur more accurately.
  • Existing ductwork, piping, and VAV boxes were removed and replaced.

Phase 3: Lighting System Energy Efficiency Upgrade

  • The building interior was retrofit with advanced lighting system controls featuring occupancy sensors, manual local dimming, and automatic daylight dimming.
  • Performed the installation of intelligent electronic ballasts in light fixtures on the first and second floors.
