The Problem

Tons of Data More building data is being produced than ever before

Lack of Insight However, this data is decentralized and in varying formats, making data exchange and analysis difficult and leaving huge opportunities for efficiency gains and market activity untapped

No Insight = No Action When decision makers understand how buildings use energy and can predict results from upgrades, they can support smarter investments, design better policies, and implement better programs

Integrated Network of Building Data Tools

BuildingSync XML

Why is this the solution? – DOE is in a unique position to provide a standardized, integrated tool set to the

market at no-cost – Tools are designed to help markets function more efficiently – Tools address each phase of a building’s lifecycle (design, operations, retrofit) – Tools serve as a foundation for private sector products to build upon – Tools aim to inform wise investments, grow new markets, and make buildings more

competitive and resilient

Asset Score

Building Energy Data Exchange Specification “The Translator” Lower the transaction costs of sharing building data by creating an easy to adopt exchange specification enabling widely used tools to communicate with ease.

Standard Energy Efficiency Data (SEED) Platform “The Database” An open source tool to automate the data aggregation, cleansing, and matching process across sources to save time, streamline complex processes, and enable organizations to gain deeper insight into their buildings.

Asset Score “Model Builder” Generates a model and score indicating the efficiency potential of the underlying assets in a building. Diagnostics and recommended EEMs identified via lifecycle cost analysis and provide a distinct output from performance scores.

BuildingSync XML “The Hand-Off” Standardized file format to facilitate the exchange of building energy audit data in a way that produces a predictable result regardless of the specific software platform being used to read the file.

Building Performance Database “Public Portal” Provide public access to anonymized real-building data for customizable queries and peer-to-peer comparisons. World’s largest building energy database with nearly 1M buildings.

Low Effort - Minimum manipulation of Asset Score exported model. Bounding of model annual and monthly usage to measured billing data. ECMs represent whole building/system improvements. Installed costs are based on estimates and savings potential are provided via ranges. Use Case – Programs looking to generate interest in downstream opportunities by investing as little effort as possible. As such, the range of ECM’s which can confidently be estimated is limited. Outcomes from Approach 1 are educational in nature. and are Intended to stimulate next steps that are more concrete. Approach 1 can be used to primarily generate opportunities..
