Measurement & Verification Data Access Guide
Background on CBEI and project funding The Consortium for Building Energy Innovation is a program of the U.S. Department of Energy’s Building Technology Program. Established in 2011 under the name Greater Philadelphia Innovation Cluster and then subsequently renamed the Energy Efficient Buildings Hub, CBEI, as it is now known, has as its mission the creation of a pathway to 50% energy use reduction in existing commercial buildings by 2030. Commercial Buildings represent half of all energy consumption in the building sector, which itself accounts for 40% of the total energy use in the U.S. Further, smalland medium-sized commercial buildings represent 95% of the commercial building stock and are the target of CBEI’s research efforts. CBEI believes that a key to successful market transformation lies in capturing data that shows the energy savings and other performance impacts of energy conservation measures. Thus, CBEI has installed extensive measurement and verification (M&V) equipment in a series of buildings. This data is open and available to researchers and this document provides guidance for accessing this data. CBEI M&V data is available for a set of buildings that captures measures in the entire building, as well as certain sections of several other buildings. The buildings and the available data are described below.
Whole-building datasets Building 101 Building Profile The building is the headquarters for PIDC at the Navy Yard, and also houses offices for site property manager, CBRE, and formerly the CBEI offices. The building was heavily instrumented in 2012 and is subject to intense research scrutiny. Building 101 is undergoing a phased energy retrofit, as measures are proposed and evaluated, and as systems reach end of life. The major EEM installed to date was a new building automation system (BAS), which in turn affected the operation of the building’s HVAC and lighting systems. While upgrading the BAS, mechanical issues were identified in the HVAC system, including installed but inoperable variablefrequency drives on the air handler fans, exhaust fans that were no longer required, and a host of inoperable valves. Experience suggests that these kinds of mechanical issues are likely to be found when upgrading dysfunctional BAS systems, particularly since some of the manual overrides in BAS systems are quick fixes to systemic problems. The building’s three cooling condensate units have also been
replaced since M&V began. Further, limited lighting upgrades have been undertaken. More details about Building 101 can be accessed on the CBEI Research Digest website: http://bit.ly/1ziZgXY.
Available Data M&V data is being captured through two systems: The building automation system (BAS) installed by Radius Systems, LLC. captures data from the building systems. This BAS data is greatly augmented through the sensors installed throughout the building. Sensor data is collected and stored by a third party, CDH,

which has created a publicly accessible dashboard. However, the full BAS data stream is not available to the public. Carnegie Mellon University (CMU) has aggregated both the BAS and sensor data and provided access through the Pi dashboard for viewing and downloading it.
Users can learn more about working with Coresight by reading the manual.
The sensor network produces 1491 data points, updated every minute, while the BAS produces 951 data points, updated every ten minutes (data is captured at 1 to 15 minute time steps). The sensor map gives an overview of the sensors attached to the data loggers. A full list of sensors is available on this spreadsheet.

Data Access Protocols CDH Energy’s dashboard, which captures the full suite of sensor data (not including BAS data) is available through their website, http://cloud.cdhenergy.com/ bldg101/ login: bldg101; password: hub. The Pi server has two main portals for viewing and interacting with Building 101’s data stream. First, the public may access this data by visiting the dashboard website, http://128.118.67.245:85/eebhub/. This public site has limited functionality compared to the Coresight portal, but does allow users to view some important building data that has been selected by Carnegie Mellon and is presented in preset dashboards. The public server does not allow for data export. Alternatively, users that are interested in viewing data that is not presented in the public portal are able to explore and export the full dataset on the PI Coresight portal. Users interested in accessing the PI Coresight portal must request access by contacting info@cbei.psu.edu. PI Public Interface

Building Profile Located adjacent to Building 101, Building 100 is a renovated historic building located at The Navy Yard in Philadelphia and functions as a multitenant commercial office space. Building 100 was instrumented in 2012. A brief description of Building 100 and its systems can be accessed on the CBEI Research Digest website: http://bit.ly/1O0KRaE
Available Data Building 100 data includes electric sub-metering, whole-building gas metering, and BTU meters to measure heating and cooling supply for the building.
Data Access Protocols Data is not accessible through a dashboard, but can be pulled into a report by CBEI. Users interested in obtaining sensor data for Building 100 must request a data transfer by contacting info@cbei.psu.edu.
Building 661 Building Profile Building 661 at The Navy Yard in Philadelphia has been named the Center for Building Energy Science and is headquarters of CBEI. The 38,000 square foot building was comprehensively retrofitted to repair damage from long neglect, to showcase energy efficiency technologies, and to demonstrate the design process and technologies used to retrofit a historic building into a highly energy efficient commercial office space. As part of the retrofit, the CBEI designed Energy Conservation Measures (ECMs) for all building systems: enclosure; lighting; heating, ventilation, and air conditioning (HVAC); and sensors and controls. The AER design phase was completed in 2012, construction began in 2013, and was completed in late-2014. Commissioning is ongoing as of February 2015. More details about Building 661 can be accessed on the CBEI Research Digest website: http:// bit.ly/1DxssNY.

to CBEI’s building-wide requirement that all technologies be scalable, “state-of-the-shelf” interventions that can be implemented at a reasonable cost. The CBEI team selected technologies that strike a balance between occupant control and automation in order to maximize comfort as well as energy efficiency. For example, the fluorescent and LED lights have ballasts that are capable of being individually controlled, allowing each unit to respond to occupancy, lighting levels, and load shed commands. In fact, most spaces in the building have vacancy sensors so lighting in vacant areas will power off automatically. In each of the three mechanical zones, heating, cooling, and ventilation is customized to the needs of the occupants and the facility programming. The building provides a wealth of data for the CBEI researchers via sub-meters for each zone that include data on the light levels, CO2, CO, relative humidity, and indoor environmental quality.

Building 489 Building Profile Across the street from the “town square” of the historic section of the Navy Yard, the 22,000 square foot Building 489 was built in 1926 and carefully renovated in 2013 to preserve its historical significance while creating a new space for a sports medicine practice. This ‘internal-load’ dominated building was selected as a research location by CBEI in order to develop experience with plug load ‘wave forms’ and calibration of energy models of internalload dominated buildings. Specifically, researchers looked to determine the application transferrable, minimum continuous metering configuration required to establish positive or negative deviations from expected, modeled, energy use in an internal load dominated health care facility. More details about Building 489 can be accessed on the CBEI Research Digest website: http://bit.ly/1BNqEQl.
Available Data Energy data is being collected in Building 489 for HVAC and plug loads. Some HVAC operating conditions – boiler water and chiller loop temperatures, as well as the boiler operating times - are also being monitored. Altogether, 57 data points are being collected in the building and are aggregated and updated daily.
Data was collected for HVAC details, system power usage, and indoor environmental quality conditions. Altogether, 151 data points were collected in the building and were aggregated and updated daily from February 2013 to February 2015
