DASH: Database for Analyzing Sustainable and High Performance Buildings™ has been working at the national level since 2004 to provide building industry professionals with measured performance information that enable better decision-making about building design, construction, operations, and maintenance.

A web-based software solution that seeks to improve evidence-based decision-making in the building marketplace, DASH is working to become a comprehensive national repository of triple bottom line building performance data. DASH enables the consistent collection of quantitative data about green, sustainable, and high performance buildings while facilitating reporting and analysis based on that information. Users can anonymously compare, analyze, and benchmark their buildings and properties to make informed decisions about energy efficiency, occupant health, and overall building performance.

DASH is working in collaboration with existing building information sources, as well as with individual users who include small and large property owners, managers, companies, organizations, and researchers.


DASH’s current functionality includes:

  • REVIEW - Facilitates direct DASH data input and storage that covers all aspects of building performance. Bulk data import is also available.
  • REPORT - DASH includes four standard reports that can be pulled dynamically for any building or portfolio to which a user has access:
    1. Single Building Report - Summarizes normalized building performance across the triple bottom line, numerically and visually comparing the single building’s performance to the DASH Average. Can be instantaneously generated for any building to which a user has access.
    2. Portfolio Comparison Report - Summarizes normalized building performance across the triple bottom line, numerically and visually comparing a whole portfolio of buildings’ performance to the DASH Average. Can be dynamically generated for any portfolio of buildings to which a user has access.
    3. Global Report on Commissioning - Summarizes commissioning and operational performance outcomes for a single building, numerically and visually comparing building performance to the DASH Average and COMMISSION Average. Can be dynamically generated by any user with access to the commissioning topic.
    4. Single Building Commissioning Report - Summarizes commissioning and operational performance results for a single building, numerically and visually comparing building performance to the DASH Average and DASH Commissioning Average. Can be instantaneously generated for any building to which a user has access.
  • COMPARE - Provides real-time comparison (both numerically and graphically) for user-selected buildings to DASH minimums, maximums, and averages for a set number and selection of normalized building performance statistics across the triple bottom line. This feature can be used for any building the user selects that s/he has access to; comparisons to the DASH Average are also provided.
  • DISCOVER - Provides dynamic query capability so users can compare user-selected buildings to a user-defined filter. Filters can be based on building size, use type, geography, data year, classification, building height, number of floors, and average number of occupants. Due to user confidentiality concerns, comparisons to sets of buildings less than 30 are not available; all comparisons are normalized and users can change normalizing factors based on what is most applicable. Once filtered, DASH minimums, maximums, and averages for the filter set and values for the specified buildings are normalized and provided for a set selection of building performance considerations across the triple bottom line. DISCOVER can be used for up to three user-selected buildings that s/he has access to; quartiles signifying each building’s comparison to the DASH Average are provided.

While many organizations are focused on various verticals of building performance data collection, no other effort has provided a singular place for building performance information across a building’s life and throughout its operational considerations. Using a consistent and industry-vetted set of data standards, while providing a user-friendly way to report, compare, and discover that information anew, DASH is addressing triple bottom line building performance in new way.

DASH includes information about green, sustainable, high performance, and aspiring-towards-high-performance buildings from a diversity of building types, geographic locations, and operational structures. Building identification information is reported anonymously and confidentially. DASH Users have the ability to compare, analyze, and benchmark their buildings and properties to make informed decisions about energy efficiency, occupant health, and overall building performance.

The development of DASH provides an opportunity to integrate numerous existing databases, bridging market segments with a comprehensive dataset that captures building performance information that includes the health and sustainability aspects of buildings, as well as building characteristic and financial data.

In 2004, Green Building Alliance (GBA) started a national discussion about collecting more information on occupant outcomes in high performance buildings. That conversation developed into DASH as it exists today, focusing on building performance across life cycles and operating perspectives. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has been involved in DASH discussions since 2004 and began supporting GBA in the DASH development process in 2008. In 2010, a NIST grant to ASHRAE and GBA enabled DASH to move from discussion and planning into a tangible reality.

Additionally, in the past several years, the world of building performance information has evolved from EnergyStar ratings and LEED certifications to the more recent municipal energy benchmarking requirements and more voluntary 2030 Districts. Even with an industry-wide push towards acquiring more information on building performance, few efforts have attempted to provide a secure environment where properties can share and compare performance for internal benefit and understanding, while simultaneously providing the opportunity to discover how performance is playing out for properties nationwide.

Thus, DASH is both a response and solution to the lack of comprehensive building performance data collection and analytic tools that use an inclusive approach. DASH provides building industry stakeholders the opportunity to better utilize and understand building performance information in a way that improves decisions about creating high performance properties of all types and sizes. There is no time better than the present, when more people are focused on building performance than ever before, for DASH to emerge.

DASH is a project of Green Building Alliance (GBA), a nonprofit organization headquartered in Pittsburgh, Pennsylvania, that inspires the creation of healthy, high performing places for everyone by providing leadership that connects knowledge, transformative ideas, and collaborative action. Founded in 1993, GBA was the first U.S. Green Building Council (USGBC) affiliate and is now a USGBC Chapter. GBA serves Western Pennsylvania and strives to be a regional and national catalyst by meeting the ever-growing and changing demands of the green building marketplace through multiple programs and initiatives.

As a small nonprofit organization, GBA has received resounding support over the years for its leadership and role as a facilitator and catalyst for DASH. DASH: Database for Analyzing Sustainable and High Performance Buildings has been a program of Green Building Alliance (GBA) since 2004.
