VALUE DELIVERED

  • 55% energy savings compared to the original facility
  • 40% reduction in lighting energy usage compared to Oregon Code requirements
  • Rooftop PV array that will produce 200,000 kWh annually, approximately 4% of full building load 

CLIENT OBJECTIVES

Originally installed in 1974, the building’s mechanical and electrical systems were outdated and high energy users. The GSA had conducted compressive studies to reduce energy usage and bring the facility up to today’s standards. With the passage of the American Recovery and Reinvestment Act (ARRA), the GSA had the funds available to modernize EGWW to meet the federal government’s Energy Independence and Security Act (EISA) and become a LEED Platinum building.

SCOPE OF SERVICES

Dynalectric Oregon installed a number of systems, including:

  • Complete Electrical
  • Lighting & Lighting Control
  • Fire Alarm
  • Tele/Data
  • Photovoltaic System
  • Closed Circuit Video System
  • Access Control 

SOLUTIONS

  • Two new 4000 amp, 480 volt electrical services and complete electrical distribution
  • High efficiency linear lighting with daylighting and occupancy controls
  • Department of Homeland Security compliant access control and video monitoring systems
  • Installed a 1 Megawatt generator for emergency power requirements
  • New design/build Class A fire alarm system that was NFPA and GSA Region 10 compliant
  • Installed (715) 250 watt photovoltaic modules and (5) 35 KW inverters for the rooftop PV array

BACKGROUND

The project was awarded on “Best Value Source Selection”. The solicitation from the GSA required that the General Contractor also include up to five first tier subcontractors. The biggest challenge (as well as the highest profile activity on the project) was installing a 180-KVA photovoltaic array on top of a high-rise tower in downtown Portland. Dynalectric had to address numerous concerns including:

  • Winter weather: Mitigating the risk of snow and ice sliding off the array to the streets below was critical.
  • Eliminating the chance of material blowing or sliding off the canopy surface during the construction. 

Dynalectric worked extensively with the other members of the design team to ensure safety while maintaining design performance. A gutter system was installed to capture rainwater coming off the array. This gutter system also prevented any snow or ice from leaving the roof. The water captured is subsequently stored in a cistern on the basement level and used to maintain water levels for the fire sprinkler system. During the original building occupancy, the cistern was actually a gun range used by armed federal officials.
