Missouri Residential Energy Code Baseline Study

Kick-Off Meeting March 29, 2016

Presentation Topics

• Overview of Project and Meeting Goals
• Rationale and Goals of Study
• Study Structure, Partners, & Process
• Data Analysis
• Results from Previous Study (Kentucky)
• Sampling Plan
• Group Discussion

2

Meeting Goals

• Inform key energy code stakeholders of the study

and data collection plan

• Get stakeholder input on Assessment Methodology

and Sampling Plan

• Facilitate an efficient data collection process through

stakeholder collaboration

3

Overview of Project

• ARRA: 90% compliance with 2009 IECC by 2017
• DED/DE contracted with MEEA to conduct residential

study to determine current construction practices relative to 2009 IECC

• Results from this study will be used to determine

statewide compliance with ARRA requirements

• New single-family homes throughout Missouri

4

Goals & Rationale of Study

• Collect in-field construction data from random

sample of homes across Missouri

• Obtain statistically-significant observations of 9 key

measures

• All data collected will be anonymous and only

analyzed on statewide level

• Use collected data as a basis to determine statewide

compliance with ARRA requirements

5

9 Key Items

• Envelope Tightness

(ACH50)

• Window U-Factor
• Ceiling Insulation
• Foundation Insulation
• HVAC Right Sizing

(Manual J Block Load)

• Window Solar Heat

Gain Coefficient (SHGC)

• Exterior Wall

Insulation

• High Efficacy Lighting
• Duct Leakage

6

Study Structure and Timeline

• DED/DE: Funding and general oversight of study
• MEEA: Management of study & subcontractors
• Matt Belcher: Outreach to builders & code officials

and coordinating site access

• The Cadmus Group: On-site data collection

Data collection begins April 6th and ends June 30th.

7

Matt Belcher (Data Collection Facilitator)

8

Data Collection Facilitator

• Calls permitting jurisdictions for recent permitting

information

• Permits are randomized
• Calls builders in order from randomized list

– Tells them about study – Requests permission to come on site

• Passes builder contact info onto Data Collector

after receiving “yes” response

9

The Cadmus Group (Data Collector)

10

Data Collector Process

• After Matt calls builder and receives a “yes,”

Cadmus will call to schedule the site visits

– Idaho area code

• Minimal Disruption to operations
• Experience in other states
• 15 homes / week
• Submitting anonymous data collection sheets to

MEEA

11

Analysis Methodology

12

Analysis Methodology

• Establish range & frequency of observations for

each key item

• Identify observations that don’t meet minimum

code requirement

– Only analyzing non-compliant items that are 15%+ of

• bservations
• Run EnergyPlus models for these items to

establish energy use (all other items kept at code level)

• Compare non-compliant energy usage to

compliant energy usage to establish savings

13

Overview of Kentucky Results

• MEEA and Cadmus conducted similar baseline

study in Kentucky as part of larger effort, funded by DOE

– 8 states are participating – Baseline Study, Training & Education, Post-Study

Sampling Plan Methodology

• Based on 2015 Census Permit Data
• Only Single Family Homes
• Permits are Weighted by County
• Then Randomly Selected
• Representative Cross-Section of Construction

22

23

Group Discussion

• Feedback on sampling plan
• Suggestions of partners/contacts to make data

collection as efficient as possible

• General discussion, feedback, and questions

24

Next Steps

• Field data collection begins April 6th in St. Louis

area

• Matt has begun calling jurisdictions & will

continue

• MEEA will organize a mid-point stakeholder

update meeting in May

– Final stakeholder meeting will take place this summer

• nce results are in
