BEDES and the DOE data system

DOE’s Vision for Performance
-
Based Approaches

By making
building energy performance clearly traceable:


Owners
, operators, and product and service providers
can
understand the drivers of
variations in building performance, identify efficiency investment opportunities, and
project the likely savings from investments.


Public
sector actors

can
tailor the design and implementation of energy efficiency
programs and policies to be most effective given local market conditions and trends
.


DOE is establishing
a foundation that the private sector can build on, through
:


Tools and methods
to analyze actual performance, and


Standard

definitions and data exchange
specifications



3

The goal is an
ecosystem of interoperable
private
and public data tools

Motivation for BEDES

The lack of standard data formats, terms and definitions is a
significant ongoing barrier to realizing the full utility of empirical
information about building energy performance.



The goal of BEDES is to facilitate the utilization and

sharing of empirical building energy performance data among
software tools and data collection and analysis activities,

more easily and consistently and at lower cost.


5

A common data format makes it easier to exchange and combine data
among all the tools, databases and platforms

The Building Energy Data Exchange
Specification (BEDES)

Background


BEDES beta




7

History of BEDES

BEDES
was originally developed for use
by the DOE


A common data format
will:


Make
DOE tools
interoperable


R
educe
reporting burdens for grantees and
contractors


M
ake
it possible for DOE to combine
the resulting
datasets to conduct further
analysis
.


The DOE is using it as the data format to support:


Tools such as
t
he
Buildings Performance Database (BPD
), the
Commercial
Building
Energy Asset Score and Home Energy Score.


Data collection for the Better Buildings program, State Energy Program grants and
Federal building benchmarking and energy performance contracting activities.


Analysis that is conducted following the Uniform Methods Project methodology

Analytical
tools collect data and conduct
diagnostic analysis

Data Sources

A
n energy
management tool that
tracks &

assesses energy &

water
consumption in
user’s buildings.

e.g. Building Management Tools,
Energy Efficiency Program
Administration Databases, Property
Tax Assessor Databases

9

ENERGY STAR Portfolio Manager

Tracks building energy and water consumption, and provides a weather normalized EUI
and a whole building score, based on actual energy performance.

10

Commercial Asset Score & Home Energy Score

Provides a whole
-
building score and identifies inefficient systems and potential capital
upgrades, based on
as
-
built physical characteristics

(independent of operations).

11

To manage
benchmarking
programs, Cities combine data

about many buildings from a range of tools and sources

Audit findings

Enables cities to manage
and
analyze data
in a private,

secure repository.

Tools & Databases

Aggregation Platform

Standard Energy Efficiency Data (SEED)
platform

Helps
State and local governments
manage data resulting from
building performance
reporting
programs
for private and/or public buildings







13

All of this data can be contributed to the Buildings Performance Database,
where it can be accessed in aggregate by the public.

Tools, Databases & Platforms

Central Platform

ne
publicly
-
accessible
database of anonymous,
empirical records.

The
BPD enables users to

analyze
trends in the energy performance and
physical & operational characteristics of real commercial and residential buildings.






Building Energy Data Exchange Specification

Overview & Tour

Kickoff Summit

BEDES beta

a brief tour

16

BEDES
-
beta Schema


8 general categories with
data fields
for
the building description, energy use
&
efficiency
measures


Systems category includes 23
subcategories


Data fields prioritized into three
“Data
Sets”: Primary, Supplementary and
SEED Additional


The Primary
d
ata fields are organized
into Priority
1 (~100 fields), Priority 2
(~200 fields
).

How do these vary?


1.
Overall scope.

e.g. Is water use, IEQ data included?

2.
How a feature is defined.

e.g. qualitative vs. quantitative
description of air tightness

3.
Classification of building system
types.

e.g. types of heat pumps

4.
Granularity.

e.g. multiple lighting types in each
space vs. predominant lighting type
for building.

Scoping Study and Work Plan

Background


Stakeholder Discussions


DOE
commissioned
scoping study

to assess broader
use

and
value to the industry


Feedback from > 40 stakeholders



The
vast majority
confirmed
the need for a common
format to facilitate
data exchange
and
aggregation


Easier
to combine information from different sources about the
same buildings


Use
the same information for multiple
purposes


Compare
information among buildings and public
programs


Stakeholders
expressed
interest in
BEDES
as the
start
for a
common data spec,
and it’s
appropriate
DOE role to
lead
refinement of the beta version
for
broader use
.


I.

Efficiency

II.

III.

by utility and other EE

Primary Stakeholder Groups

Owners

Building owners &
managers, staff, tenants,
asset managers, etc.


Implementers

Energy auditors, A/E,


contractors,

ESCOs,

Administrators

Public Entities

Financiers

External Stakeholders:

Efficiency
programs and state & local governments


Drive a significant volume of data collection through their programs and policies


Wish to align data formats to ease program reporting and evaluation burdens, facilitate
comparisons between jurisdictions, and make it easier to combine data for other uses.

Building owners and managers


Make decisions about capital investments or the operation of their buildings


Better data would lower the cost and effort required to assess savings opportunities in
individual buildings and develop strategies across portfolios

Software developers and project contractors


Are often ultimately responsible for directly collecting and managing this data


A common format would decrease the cost and increase the availability of data

.

Purpose Of BEDES Stakeholder Process


LBNL has been tasked by U.S. DOE to develop BEDES, and to consult
with stakeholders along the way


Purpose of the stakeholder process is to provide both strategic and
technical advice to LBNL


Stakeholder process serves in advisory, sounding board capacity to
LBNL (seeking consensus or convergence among stakeholders as much
as possible)


LBNL is responsible for making final BEDES
-
related recommendations
to DOE

The Strategic Working Group (SWG)


Purpose
: Develop a strategy for widespread adoption and future
management of BEDES, including:


Topics
:


How to leverage and harmonize existing specifications, including
options for how other specifications can relate to BEDES,


Promotion of voluntary use in external tools, programs and
guidelines,


Process and responsibilities for updating and
maintaining BEDES
over
time


Meetings
: The SWG will meet 4 times in person during the nine
-
month
work group process.


36

The Technical Working Group (TWG)


Purpose:

Provide input on the detailed BEDES specification, covering:


Tasks:


Module I: Facility Level Data

(Building Staff & Tenants; Building
Characteristics and Uses; and Whole Building &Tenant Energy
Consumption), and


Module II: Equipment Level Data

(Contractor Information; Project
Structure & Financials; Equipment and ECM Characteristics; and
Equipment and ECM
-
Level Energy Consumption)


Meetings:

The TWG will meet for four in
-
person meetings and up to
three web
-
enabled conference calls, as needed.


Sub
-
Group Oversight/Integration
: The TWG will also direct the work of
two sub
-
groups reporting back to them
-
one focused on residential
buildings and the other focusing on buildings. Certain aspects of multi
-
family buildings will likely be covered in the commercial sub
-
group and
other aspects in the residential sub
-
group.


37

Building Sector Sub
-
Groups of Technical Work Group


Purpose
: Review and provide detailed feedback on BEDES:


Approach
:


Two Modules: Facility & Equipment Level Data


Two Sub
-
Groups for each module with one focusing on residential
issues and the other focusing on commercial issues

for four total
sub
-
groups.
Certain aspects of multi
-
family buildings will likely be
covered in the commercial sub
-
group and other aspects in the
residential sub
-
group.


Each Sub
-
Group is expected to meet three
-
to
-
four

times for each
module via web
-
enabled conference calls


The Sub
-
Groups will report back to TWG
