Utility Reduction and Energy Conservation Plan (URECA)

The goal of URECA is to reduce energy consumption intensity 25% in FY2015 from the FY2005 baseline.   Energy conservation measures (ECM) are presented in the URECA plan and are being implemented across campus.  The measures include steam trap maintenance, lighting retrofits and controls, building HVAC shutdowns, thermostat temperature standards, water conservation, building re-commissioning, and building continuous commissioning through a new program titled the Stainable Performance Program.  Weather normalized energy consumption intensity for FY2012 was down 20.1% versus the FY2005 baseline.

Energy Services Contract

Emory contracted with Siemens Building Technologies, Inc. to perform energy audits, develop and implement conservation measures in support of URECA.  They have completed two phases covering 2.65 million square feet.  Emory self-performed phase III covering .8 million square feet.

Ongoing Support for Energy Conservation

On a monthly basis, energy consumption intensity is calculated by building and grouped by building classification.  High intensity consumption buildings in each classification are targeted for close inspection of HVAC equipment performance.  Energy consumption intensity is also analyzed on an annual basis.

Real time Energy and Water Consumption Monitoring

Many buildings around campus are installing Lucid Design Group Building Dashboard® to monitor and display real-time electricity use per floor and heating and cooling energy consumption. Touch-screen lobby displays encourage participation and friendly competition among residents.  This information is available to view on-line at: http://www.buildingdashboard.net/emory/

Boiler Flame

Emory operates five 110,000lb/hr steam boilers that consume natural gas and fuel oil when the natural gas supply is interrupted. The boiler plant annually consumes about .87 billion cubic feet of natural gas to produce about 750,000,000 lbs of steam. The steam is distributed underground to 55 buildings on the central campus for space heating, water heating, humidification, and process loads. Steam consumption is metered at every building.

Chilled Water Plants

Three chilled water plants provide cold water for space cooling to 48 buildings through underground distribution systems. The plants provide annually about 50,000,000 ton-hours of cooling by supplying 42F water used to cool and dehumidify air entering and circulating in the buildings. The plants have a combined capacity to supply 22,000 tons of cooling. Chilled water consumption is metered at each building for all of the buildings on the distribution system.

Domestic Water

DeKalb County annually supplies about 370,000,000 gallons of domestic water. Emory uses a private distribution system in the main campus area. All buildings are metered for domestic water.

Natural Gas

Atlanta Gas Light annually delivers approximately 1 Billion cubic feet, purchased through marketers, directly to some facilities and to the central steam plant. The natural gas market is deregulated in Georgia which gives Emory access to the natural gas commodity market.
