The Commercial Building Partnership (CBP) paired selected commercial building owners and operators with representatives of DOE, national laboratories, and private sector exports to explore energy efficiency measures across general merchandise commercial buildings.
This presentation highlights the importance of modeling the off-design performance of equipment in data centers as a consequence of their dynamic behavior and describes an experimentally validated tool for modeling the energy use of the data center and cooling infrastructure.
This Technical Support Document describes the process and methodology for the development of the Advanced Energy Design Guide for Large Hospitals: Achieving 50% Energy Savings Toward a Net Zero Energy Building (AEDG-LH) ASHRAE et al. (2011b). The AEDG-LH is intended to provide recommendations for achieving 50% whole-building energy savings in large hospitals over levels achieved by following Standard 90.1-2004. The AEDG-LH was created for a “standard” mid- to large-size hospital, typically at least 100,000 ft², but the strategies apply to all sizes and classifications of new construction hospital buildings. Its primary focus is new construction, but recommendations may be applicable to facilities undergoing total renovation, and in part to many other hospital renovation, addition, remodeling, and modernization projects (including changes to one or more systems in existing buildings).
This Fact Sheet provides an overview of the Better Buildings Workforce Guidelines project. The Department of Energy (DOE) and the National Institute of Building Sciences (NIBS) are working with industry stakeholders to develop voluntary national guidelines that will improve the quality and consistency of commercial building workforce training and certification programs for five key energy-related jobs.

The lack of empirical data on the energy performance of buildings is a key barrier to accelerating the energy efficiency retrofit market. The DOE’s Buildings Performance Database (BPD) helps address this gap by allowing users to perform exploratory analyses on an anonymous dataset of hundreds of thousands of commercial and residential buildings. These analyses enable market actors to assess energy efficiency opportunities, forecast project performance, and quantify performance risk using empirical building data. In this paper, we describe the process of collecting and preparing data for the database, and present a peer-group analysis tool that allows users to analyze building performance for narrowly defined subsets of the database, or peer groups. We use this tool to explore a case study of a multifamily portfolio owner comparing his buildings’ performance to the peer group of multifamily buildings in the local metro area. We also present a performance comparison tool that uses statistical methods to estimate the expected change in energy performance due to changes in building-component technologies. We demonstrate a low-effort retrofit analysis, providing a probabilistic estimate of energy savings for a sample building retrofit. The key advantages of this approach compared to conventional engineering models are that it provides probabilistic risk analysis based on actual
measured data and can significantly reduce transaction costs for predicting savings across a portfolio.
While the availability of “big data” about building energy performance is increasing in response to market demands and public policies, the lack of standard data formats is a significant ongoing barrier to its full utilization. To overcome this barrier, the U.S. Department of Energy (DOE) and Lawrence Berkeley National Laboratory (LBNL) developed the Building Energy Data Exchange Specification (BEDES).
BEDES is designed to enable the exchange, comparison, and combination of empirical information by providing common terms and definitions for data about commercial and residential building’s physical and operational characteristics, energy use, and efficiency measures.
This paper describes the BEDES development process, scope, structure, and plans for implementation and ongoing updates.
With 7 hospitals and 22 physician locations serving more than 9 Wisconsin counties, ThedaCare has ample room to implement and reap the benefits of building efficiency measures. At the Appleton Medical Center, ThedaCare’s Lighting Energy Efficiency in Parking (LEEP) Campaign Award winning project involved replacing inefficient medium-wattage HID lighting fixtures at a 126,000 square foot parking structure with high efficiency low-wattage LED fixtures. The resulting energy savings exceed 80 percent of the previous usage. A 100-year old company and the third largest health care employer in Wisconsin, ThedaCare has now implemented LED exterior lighting throughout Appleton Medical Center.
The JBG Companies (JBG), an investor, owner, developer, and manager of real estate in the Washington, D.C. Metropolitan Area, achieved almost 50% energy savings compared to energy code by using a combination of high efficiency LEDs coupled with lighting controls for the parking structure at the National Cancer Institute (NCI) Shady Grove in Maryland. The NCI
parking structure was recognized by the Lighting Energy Efficiency in Parking (LEEP) Campaign for the Highest Percentage Energy Savings in a Single Parking Structure (New Construction)
and Highest Absolute Annual Energy Savings in a Single Parking Structure (New Construction). In addition to its 2014 LEEP Campaign Award, the buildings have also been recognized in 2011, 2013, and 2014 by both local Maryland organizations and national organizations.
