Empirical, non-synthetic (or modeled) data from multiple industry sources

Cleansed, validated, and stored within a standard taxonomy

Statistical method leveraging “pre” and “post” building data

Normalization of data points that will not severely misrepresent results

Elimination of the reliance on building-to-building comparison approach

Energy Performance Forecasting Tool to forecast potential energy savings

Historical Perspective - Energy Performance Forecasting ToolTool Overview and Screenshots

Summary Description

Geared toward ESCOs, building engineers, and energy efficiency experts to evaluate the energy savings potential of different measures

Based upon an actuarial methodology that is markedly different than today’s standard engineering approaches

– Not based on a 1-to-1 comparison of pre and post retrofit energy consumption

– Compares target building to buildings that share similar characteristics and performance features

Calculates the energy savings potential for a specific set of user-identified measures by comparing similar buildings with and without those measures

Savings opportunity depicted by a curve (probability density function) that demonstrates a range of savings potentials and the probability of attaining that level (e.g. 30% probability of savings at least 50kWH, 95% probability of saving at least 90kWh)

Design Principles

DATA PLATFORM ANALYTICAL TOOLS

• Explore Tool• Compare Tool

API

Third Party Tools

By design, the BPD:• Provides access to actual data on existing buildings - not modeled data or anecdotal evidence.• Enables analysis of data without revealing information about individual buildings. • Cleanses and validates data from many sources and translates it into a standard format.• Allows users to create third party applications using the database through an API

8

BPD Makes Data Available to a Broad Audience

Value for decision-makers (e.g., building owners and policymakers):Analyze narrow peer groups defined by geography or building-specific factors• Regional markets, • Specific building or equipment types• Range of energy use intensities.

9

BPD Tool - ExploreAllows users to:• Filter the dataset based on building type, location, size, equipment, etc.• Analyze using bar charts, scatterplots and tables• Enter information about a building to see how it compares to a group

About the Data: Statistics and Standardization

The database contains > 800,000 buildings – 73,000 commercial– 738,000 residential

The data represents – 1.3% of the U.S. commercial building stock (CBECS, 2009– 0.6% of the U.S. residential building stock (RECS, 2009)

All the data is cleansed and standardized using the Building Energy Data Exchange Specification (BEDES)

SEED Platform

The Standard Energy Efficiency Data (SEED) Platform™ is an open source software application that helps organizations easily manage data on the energy performance of large groups of buildings. Users can combine data from multiple sources, clean and validate it, and share the information with others. The software application provides an easy, flexible, and cost-effective method to improve the quality and availability of data to help demonstrate the economic and environmental benefits of energy efficiency, to implement programs, and to target investment activity.

The SEED Platform™ is designed to help organizations manage and share large datasets about building performance: state and local governments implementing building benchmarking regulations, building managers, energy efficiency program managers, and more. SEED can help public entities that are implementing benchmarking and disclosure laws, but the core functionality is highly flexible and can be useful for a range of other purposes.

Potential Next steps

• Contemplate/design a hybrid system that uses both measured demonstration or test data from real projects and allows people to apply that data to e.g. other building types or climate zones via modeling

• Use something like the Technology Performance Exchange (TPEx) and Building Component Library (BCL) to store characteristics of the measures and keep adding new measures as they become available.

• For measures where measured data isn’t yet available, Use a simulation tool (DOE-2, Energy Plus, Transys, etc) to estimate the performance of the measure and "fill the cracks".

• Develop a process to target and collect data for all measures to be considered so that a living ever improving database of measure performance is created
