Wake Forest University
OP-1: Building Operations and Maintenance

Wake Forest University has continued to expand its efforts to improve performance in operations and maintenance of existing buildings. We have not pursued LEED-EB certification of any buildings at this time; however, several campus-wide and building-specific programs addressed in LEED-EB are complete or in various stages of completion.

Campus-wide Initiatives include:

• Sustainable sites:
o Zipcar car sharing program
o New bike racks
o Expanded shuttle routes
o Tree care policy
• Materials & Resources
o Improved procurement policies
o Waste Reduction & Recycling position created
o Green cleaning chemicals
• Indoor Environmental Quality
o IAQ sampling for troublesome areas can be done internally through an Aircuity air monitoring instrument to provide thorough IAQ analysis and reporting capabilities
o Campus Smoke Free Policy was recently implemented

Building Level Initiatives Include:

• Water Efficiency – From our efforts listed below, the university has realized greater than 11% reduction from the baseline year to FY 2007.
o We have sub-metered electricity and water in nearly all of our primary buildings, and have added 6 chilled water sub-meters and are pursuing more chilled water sub-metering.
o Standards for reduced flow fixtures have been set for new buildings and modernizations: ½ gpm faucets, 1/8 gpf urinals, dual flush toilets, and 1.5 gpm showerheads: (From our standards and the efforts listed below, the university has realized greater than 25% reduction in water consumption in each of the buildings upgraded.
o Showerheads have been changed out in all residence halls to low-flow fixtures.
o Other fixture upgrades are complete in all of the residence halls and 20% of overall space.
o Cooling Tower Water Management – Chiller Plants have been upgraded with conductivity meters to automate bleed control.
• Energy and Atmosphere - From our efforts listed below, the university main campus has realized greater than 10% reduction in electrical consumption and a greater than 14% reduction in natural gas and oil consumption from the baseline year to FY 2011.
o Maintenance Practices – where feasible, incandescent bulbs have been replaced with CFLs. CRLs are standard replacement bulbs as incandescents burn out.
o Operating hours have been instituted in our academic and administrative buildings with temperature setbacks occurring during unoccupied periods.
o An aggressive winter break setback program was instituted to reduce setpoints to 55 degrees over the extended winter break period.

• Renewal Dollars & Energy Programs
o Chemistry – Demand-based Ventilation, Heat Reclaim, and updated controls were installed during the renewal of the laboratory exhaust and make-up airs systems.
o Recent Lighting Upgrades were completed in approx. 25% of academic and administrative buildings, including occupancy sensors, T12 to T8 conversions, and incandescent to CFL replacements.
o Multi-phase Winston Hall (Biology) AHU replacements underway will renew mechanical systems, upgrade controls, and improve efficiency as well as comfort for the occupants.
o Scales Fine Arts Building - Our 1st Retro-commissioning was completed, several corrections have been made, and it is expected to become a pilot program for future efforts.
o Upgrades to our Building Automation System and Preventive Maintenance Programs have provided better tools for our technicians and improved the reliability and comfort of our systems.
o Over 97% of our electric usage is sub-metered and/or electronically monitored at the building level.
o Steam Plant Controls have been upgraded with improvements to plant efficiency and monitoring capabilities.
o Indoor Environmental Quality
o Green Cleaning Chemicals have been introduced across campus and a new cleaning methodology (OS1) is in place in several of our buildings and is being expanded over time.
