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.

A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.
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.
Retail buildings in the U.S. are second only to office buildings in total energy consumption and represent approximately 13% of energy use in commercial buildings nationwide. The Advanced Energy Retrofit Guide for Retail Buildings presents general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures to provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. This guide is primarily designed for facility managers and energy managers of existing retail buildings of all sizes.
The Advanced Energy Retrofit Guide for Grocery Stores was created to help grocery store decision makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
Work with the buildings industry to develop and maintain data, methods, and tools to understand and improve the sustainability of buildings at a fundamental level and continue to develop and support the U.S. Life Cycle Inventory (LCI) Database, which provides the starting point for LCA.
Method for testing and diagnosing the simulation capabilities of the exterior envelope portions of building energy simulation programs. BESTEST (Building Energy Simulation TEST) evaluates design and analysis tools relative to their ability to adequately model the envelope dynamics of buildings. It has been adapted for certifying tools for Home Energy Rating Systems and by other organizations.
This sophisticated, yet easy-to-use software application trains itself to create a “smart model” of your building and compares daily energy consumption against this norm. The Energy Expert will tell you whether your facility over-consumed; under-consumed or used about the right amount of energy through a convenient email notification.
