Dartmouth College Campus Energy and Sustainability Management System
Quarterly Progress Report for
New Hampshire Greenhouse Gas Emission Reduction Fund
Reporting Period: August 1, 2010 through October 31, 2010
1. Program Title: Campus Energy and Sustainability Management System (CESMS)
2. Program Type: The Campus Energy and Sustainability Management system will reduce energy use and associated greenhouse gas emissions at Dartmouth College by using a web-based interface to track, report, and optimize building energy performance. The project supports items 5, 7, 8, 10 and 11 in the Public Utilities Commission’s Request for Proposals issued February 23, 2009.
3. Overview of Progress During the 4th Quarterly Reporting Period:
3.1. Planning
3.1.1. Functional Requirements Specification (FRS) Development: Final details were settled in the FRS during the 4th quarterly reporting period. The system reporting structure and format of sustainability indicators, energy alarm routines, utility billing data outputs and aggregation of meter data is now determined. See Exhibits 1 and 2.
3.1.2. Meter Automation Plan– The metering automation plan was updated during the quarter to reflect ongoing minor changes required at the field level. Planning for installation of 17 electrical submeters for the Tuck GreenLite project, described in Section 3.18, below, was completed, including preparation of detailed plans and specifications and a bid package for contractor installation. See attached Exhibit 3 for the latest Diagram of the entire Campus Metering Automation Plan, revised to reflect the above additions/deletions.
3.1.3. Metering Automation Equipment – There were no substantial changes to metering automation equipment during the 4th Quarter.
3.1.4. Server Software – Rockwell is running both a Development and a Production version of their VantagePoint software on system severs. The Development version is being used to try out an Advanced Type Modeling structure for BMS points, and the Production version is being used as the main daily tool for system trending and publishing of reports. Separate servers are being used for collection of Energy Metering data (RSEnergyMetrix). Another server (Rockwell FactoryTalk Historian) will be used for the collection and storage of Heating/Electric Plant data (planned for installation during the 5th Quarterly Reporting period). See Exhibit 4 for diagram indicating the Campus Energy and Sustainability Management System Server Hardware/Software configuration.
3.1.5. Connection to BMS Systems – Connection to the Honeywell and Johnson Controls BMS Systems is completed. We are currently structuring data point collections for HVAC equipment into an Advanced Type Modeling structure

within the Rockwell VantagePoint platform in order to make the systems easy to find and view on a “tree structure” and for automated fault detection routines to be run using user-scripted rules.
3.1.6. Connection to Heating/Electrical Plant SCADA Systems – Plans for connection to data points in the Heating/Electrical Plant are finalized. Our plan is to install the server and data historian software during the upcoming December (2010) break period. ABB, our Heating/Electric plant process control vendor will set up a data point server on the process control side and then Rockwell Automation will install a FactoryTalk Data Historian on the Campus Energy & Sustainability Management System side of the project. This will keep the two worlds separate, yet gain us real-time access of energy-production data (#6 fuel oil flows into each boiler, pressures, temperatures, cogeneration electrical production, main steam production and steam flows out to the campus, etc.)
3.1.7. Energy “Tiger Team” - Our “Tiger Team” continues to meet with the campus Energy Program Manager on a regular basis. The meetings are held on weekly basis, to address operational issues that are being detected via the Campus Energy and Sustainability Management System (CESMS). As a result of these meetings, we have turned our attention to Berry Library, our single largest energy consuming building. Using the CESMS as an essential discovery and trending tool, we have embarked on a program of recommissioning the main air handling systems and terminal air volume control systems for the building. We have discovered that the outdoor air damper control actuators are broken or are in serious disrepair which has resulted in excessive use of outdoor air, preheat (steam), and cooling (chilled water) --- See Exhibits 5 & 6 for Examples of AHU-3 and 4 Operating Issues.
From this knowledge, we have established a plan to install a new air sensing and control system (Aircuity) which will much more accurately detect and signal the required levels of ventilation for each air handling system. We are also planning for the replacement of all the main ventilation damper actuators with precise electronic control devices. We have also commissioned a consulting engineer to review and re-specify minimum ventilation flow rates for each of the building’s 5 main air handlers and for each of the building’s 230 variable air volume boxes. The main air handling project work will be done during the 5th quarterly reporting period and the zone level sensing and VAV rebalancing will be done during the 6th quarterly reporting period. We will also continue to meet to discuss further issues on other major energy using buildings.
3.1.8. Beginning of Formal Academic Collaborative – During the 4th Quarter, we began our formal relationship with the Tuck School of Business and Lorie Loeb, Research Associate Professor in the Computer Science department. During this period, we installed 17 new electrical sub-meters on the electrical services serving the 7 residential spaces located within the Tuck LLC and Whittemore Hall buildings. Provisions were also made for installation of 7 HP TouchSmart PanelPCs on the walls in the common spaces for each of these living areas. (Costs for all of this work will be covered under a separate gift from the most recent Tuck School graduating class with supplemental help by the Tuck School administration). These systems will be energized during the 5th Quarterly reporting period. The intent is for the residents to be able to see the impact of

their individual energy use on the collective use of the floor, thereby resulting in positive behavioral changes. The GreenLite Dartmouth project will provide programming and compelling graphic displays for the PanelPC locations to encourage use of these energy-feedback systems. There GreenLite display system features a “competition mode” as well as other interesting features.
The systems will be the subject of an academic study to monitor the results of real-time energy feedback. We will incorporate the results of this closely-controlled project into the actions of our ongoing CESMS work.
3.2. Execution
3.2.1 Execution of Task 1 through Task 3 items continued during the 4th quarter reporting period. Activities principally involved Task 1 items related to meter automation by Dartmouth’s internal Trade Shop labor force. We have made good progress in meter automation, now being able to see greater than 95% of the campus electrical load and approximately 85% of campus steam load. At this point, all of the high priority (top energy using buildings) have had their meters automated. In some instances in the tables below, the % complete values are subjective rather than quantitative due to differences in the line item descriptions between the budget prepared and submitted by Dartmouth with its RFP submission and the listing of Tasks prepared by the NHGHGER Fund. These tables are presented to indicate general progress in each of the task areas. The Detailed Cost vs. Estimated Budget form attached as a PDF file, presents the financial comparison between the project budget and the 4th Quarter costs.

4. Work to be Completed During the Next Quarter:
4.1. Planning
4.1.1. Facilities/Academic Collaboration: We will finalize the details of the Tuck GreenLite collaboration to monitor the impact of real-time energy displays for the Business School residential living facilities (See Exhibits 7 & 8 for examples of graphic screen concepts developed by the GreenLite team for the upcoming metering project). Control, experimental and competition groups will be set up between the 7 new monitoring and display locations. Our plan is to develop case studies for these buildings where occupant behavior accounts for a relatively high proportion of total building energy use.
4.1.2. Heating/Electric Plant Monitoring Points: We will install the equipment and software for integration of Heating and Electric Plant energy monitoring points into the CESMS. The points will be used to determine the energy inputs on the supply side of steam and electric production and for determining overall system energy efficiencies.

Dartmouth College 4th Quarterly Report Date: 1/11/2011 Page 5
4.1.3. Fault Detection Algorithms: We will continue working with Rockwell on development of fault detection algorithms that will analyze energy system performance in the background while we are using the system for other functionality. The result will be a series of exception reports targeted specifically at the systems which appear to be operating inefficiently according to rules which we develop and input to operating models of various system types.
4.1.4. Semi-Manual Data Inputs: We will finalize the upload data set configurations that will allow us to capture not only the automated meter data but the ongoing historical record of other energy or resources used or disposed of by the campus. Examples include stand-alone electrical meters (non-automated off-campus meters), fuel oil, propane and diesel fuel drops, water and sewer use, gasoline use, solid waste, recycling, composting, etc. We will also create an upload data set that includes all of the on-campus building-by-building energy use history for steam, electric and chilled water dating back to 1982.
4.2. Execution
4.2.1. Metering Automation: Continue automating the remaining approximately 40 metering locations, picking up the remaining electrical, steam and chilled water meters.
4.2.2. Establish Building Energy Baselines: We will continue developing building energy baselines as additional building energy meters are brought on line during the 4th quarterly reporting period (See Exhibit 9 for Energy Prediction vs Actual Use at Remsen Hall)
4.2.3. Connection to Heating/Electrical Plant SCADA Systems: We will complete connectivity to the Heating and Electrical plant control system data via an OPC server and a Rockwell FactoryTalk Historian.
4.2.4. Refine Efforts of Energy “Tiger Team”: We continue with our energy “Tiger Team” meetings and will set several recommissioning projects into action. These will include:
• Recommissioning of individual building CHW distribution system controls to improve overall Central Chiller Plant differential temperatures
• Recommissioning of the large air handling systems serving the Berry Library complex. As part of this work, we will use the CESMS to help rebalance several hundred variable air volume boxes to lower minimum flows. Currently the minimum settings are relative high, causing spaces to overcool during lower load periods..
4.2.5. Kiosks: We will continue detailing content for the building-level energy display kiosks.
4.2.6. Implementation of Additional Sustainability Indicators: We are beginning to provide web-based visual displays for tracking Sustainability Indicators on the CESMS. These include GHG’s, solid waste, recyclables and water use. Methods for easily inputting data into the CESMS will continue to be developed during the 4th quarterly reporting period.

Berry Library AHU-3 12/8/10
Effect: Steam Preheat is continuously cycling, trying to make up for the effects of constantly cycling mixed air dampers. In actuality, the Preheat coil should not even be needed at the current outdoor air temperature of about 28 Deg F. Replacing the damper actuators and retuning the control loops will eliminate the use of Preheat under these conditions.
Problem Identified: Continuous cycling of damper controls identified by Campus Energy Management System. Wildly cycling dampers are causing the system to need preheat energy when, if controlled properly, it would otherwise NOT be necessary. Cause: Tracked to major damper linkage and damper positioner problems. Solution: New beefy electronic actuators will replace current setup allowing even temperatures and control to be achieved.
Effect: Mixed air temperature swinging between 40 and 50 Deg F. Should be constant an nearly 58 Deg F
