Dynamic pricing electricity tariffs are now the default for large customers in California, and provide federal facilities new opportunities to cut their electricity bills and help them meet their energy savings mandates. This fact sheet will help California federal facilities take advantage of these opportunities through “rate-responsive building operation,” which involves designing load management strategies around a facility’s variable electricity rate, using measures that require little or no financial investment. Most facility types can reduce or shift some electric load during times when rates are higher. Facilities that can curtail with a 24-hour notice may be especially good candidates for dynamic pricing programs.

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.
Report by the National Institute of Building Sciences and the Green Sports Alliance looks at ways the nation’s sports venues can make an impact by reducing their energy and water use. The report considers the potential water and energy reductions the U.S. sports sector could make, and highlights the financial savings some leagues and teams are already seeing from putting such efficiency initiatives into place. The report looks at the progress already being made in the nation’s sports venues, challenges to widespread improvement and opportunities to move forward.
In 2016, a project team of representatives from the National Institute of Building Sciences and the Green Sports Alliance began working on this project with input from the U.S. Department of Energy and the U.S. Environmental Protection Agency. The team looked at the existing data; conducted workshops and webinars; launched an industry survey; and interviewed representatives from across the sports industry. More than 125 industry representatives participated in these activities, and an additional 20,000 stakeholders received information on the project. This report compiles that data and sets a path for future implementation.
The Recreation Center Efficiency Solutions Package aims to support municipalities nationwide with selecting efficiency improvements to reduce energy and water use at existing recreation centers by at least 20%. This toolkit is a product of a collaboration between the City of Atlanta and Southface Energy Institute. This package intends to inform local municipalities on how to approach conserving energy and water, and implementing institutional efficiency policies across a portfolio of recreation centers.
An object-oriented program that allows the user to quickly build models of complex physical processes by connecting equation-based calculation modules from an object library. SPARK (Simulation Problem Analysis and Research Kernel) creates an executable simulation program from this network ready to be run.
COMCheck addresses the enforceable provisions in commercial building energy codes based on ASHRAE/IESNA Standard 90.1-1989/1999 and IECC 1998, 2000 and 2001 that are applicable to commercial and high-rise residential projects, including building envelope, lighting, HVAC, and service water heating requirements. The software is designed to streamline the energy code compliance and approval process and is focused on the needs of those who design, build, and enforce building codes for commercial and high-rise residential building projects. It is available in Windows, Mac, and Web versions.
The Outdoor Air Economizer (OAE) diagnostic module monitors the performance of air-handling units and can detect over 20 different basic operation problems with outside-air control and economizer operation.
