Albina Head Start – Richard Brown Center

Head Start

The Albina Head Start – Richard Brown Center is located at 606 NE Ivy in Portland. The facility has two levels above ground and a basement. The total area of the facility is 7,800 sf. The building consists of three separate houses are attached by a common corridor. Four 80 MBH standard efficiency (80%) furnaces provide heat to the basement, 1st, and 2nd of the facility. Four electric thermostats control the split systems that heat and cool the facility. MSE evaluated the following energy efficient measures for the facility:

  • Replace existing standard efficiency furnaces with 92% efficient condensing furnaces

  • Install zone damper control (VVT system) for basement and 1st level split systems (F-1)

  • Replace electric thermostats with electronic programmable thermostats on F-1, 2 & 3

Jesuit High School

Jesuit High School

Jesuit High School is a 220,000 sf facility. The building envelope is as follows: 8” CMU with unknown insulation value, double pane windows, and R-19 roof insulation. A central steam plant serves the campus. The steam plant consists of (2) low-pressure steam boilers as follows: a 5100 MBH Weil-McLain cast iron sectional and a 9000 MBH West Coast water tube. The Business Center has a 300 MBH hot water boiler. Buildings that were constructed after the 1970’s have steam-to-hot water heat exchangers and hot water radiators in all rooms. Buildings constructed during the original construction (early 1950’s) have steam radiators. MSE evaluated the following energy efficient measures for the facility:

  • Install gas-fired infrared heaters in old and new gyms

  • Install CO2 control and variable speed drives on the air handling units on MAU units serving Xavier and Ignatius Halls

  • Install VSD’s on RTU’s on Science Building and Performing Arts Building

  • Install CO2 sensors and demand control ventilation control in Performing Arts Building

  • Install de-stratification fans in new and old gyms

  • Install Me-Link Intellihood controls on kitchen exhaust hood system

  • Occupancy sensors in Performing Arts Building classrooms to set back temperature when space not occupied

  • Remove buildings from central steam plant and install local condensing hot water boilers at each building

  • Install CO2 sensors in both gyms and VSD’s on air handlings units and provide ventilation demand control through existing DDC system

  • Replace 300 MBH cast iron boiler in the Business building with a 300 MBH condensing boiler

 

Portland Public Schools Educational Service Center

PPS

The Portland Public Schools Educational Service Center located at 510 N. Dixon Ave, Portland, OR and is a 285,000 square foot facility that contains administrative offices, boardroom, warehouse/shipping/receiving area, and industrial kitchen, among others. The central boiler plant for the facility consists of (2) 2,500 MBH and (1) 1,250 MBH Cleaver Brooks firetube boilers. The central chilled water plant is located in the basement adjacent to the boiler plant. The chilled water plant has two chillers and the central air handling system is served by a single built up air handling unit (AHU-1). MSE evaluated the following energy efficient measures for the facility:

  • Replace existing (2) firetube boilers (Eff. = 80%) with high efficiency condensing boilers.

  • Replace (2) forced draft cooling towers with induced draft open cooling towers.

  • Install Variable Speed Drives (VSDs) on (2) existing forced draft cooling tower motors.

  • Install infrared heat in the carpentry shop and adjoining electronics high bay area to replace forced air heating system.

  • Install infrared heat in the metal shop, the Multnomah County maintenance shop and the glazing shop to replace existing forced air heating system.

  • Remove steam boiler B-3 and replace with quick recovery steam cleaning unit for use in the kitchen.

  • Install infrared heat in the warehouse/shipping/receiving area to replace forced air heating system HVU-18.

  • Install infrared heat in the maintenance high bay corridors to replace forced air heating systems.

  • Install VSD on carpentry shop air handling unit fan in HVU-2.

  • Install VSD on machine shop air handling unit fan in HVU-1.

  • Install VSDs on supply fans in maintenance area high bay corridors heating and ventilating units HVU-13 thru 17.

  • Install VSD on the Multnomah County maintenance shop and adjoining glazing area air handling unit fan in HVU-5.

  • Install VSD on electronics repair high bay area air handling unit fan in HVU-4.

  • Install VSD on the warehouse/shipping/receiving high bay area air handling unit fans.

  • Install new DDC system to control all central plant, air handling units, coils, dampers and VAV terminal units.

  • Install solid-state control system on compressor rack in kitchen.

  • Recover heat from compressor rack in kitchen to preheat hot water.

  • Perform more frequent filter changes and maintenance on the warehouse/shipping receiving area forced air-heating system.

  • Install CO2 demand ventilation in boardroom area.

  • Install de-coupled chilled water distribution system with VSDs on secondary chilled water system.

  • Install de-coupled hot water distribution system with VSDs on secondary hot water pumps

  • Remove 3,000 sf single pane skylight from foyer area and replace with roof to match existing.

  • Install timed override control for lighting in building for weekend, holiday and after hour workers.

  • Replace constant volume reheat air distribution in Records Management Area with VAV reheat system.

  • Install Carbon Monoxide (CO) control on exhaust system serving warehouse area.

  • Install VSDs on variable pitch vane axial supply fans SF-1 and SF-2.

  • Install VSD on variable pitch vane axial supply fan SF-3.
