Market Driven Residential Energy Codes: Comparing Performance In A Changing Technical Environment, Code Official Survey Results, Florida Solar Energy Center, Karen Fenaughty

FSEC Energy Research Center®

The DOE Code Survey conducted for this project was launched on 2/18/2020 and closed 3/20/2020. There were 907 participants responding to at least some portion of the 48 question survey, though some questions received poor attention. Note that the number of responses to each question varies by design and depends on answers to prior questions. Further, multiple answers are sometimes allowed.

Comparison Of The 6th Edition Florida Building Energy Conservation Code With Iecc 2018 & Ashrae 90.1-2016, Florida Solar Energy Center, Jeffrey Sonne

FSEC Energy Research Center®

This study provides a comparison between the 6th Edition (2017) Florida Building Code, Energy Conservation and 2018 International Energy Conservation Code (IECC), based on approved 2015 to 2018 IECC changes included in the International Code document. And provides a stringency evaluation and cost-benefit analysis for those changes that impact energy use, to provide guidance for the upcoming 2017 to 2020 Florida Energy Code change cycle.

Why Doesn't 25 Years Of An Evolving Energy Code Make More Of A Difference?, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

This paper was presented at the 2015 Behavior, Energy and Climate Change Conference (BECC). New and more stringent building energy codes are implemented with the assumption and expectation that significant energy conservation will occur. While simulation and various analysis methodologies may be reasonably sound at estimating the energy impact, the actual impact is largely dependent upon new code enforcement and occupant behavior. This work is based upon the research question: Do homes built to a newer energy code deliver measurable energy savings compared to homes built to a much earlier energy code? This residential research study was focused on comparing …

Cost Effectiveness Of 2015 Iecc Compliance Using The Hers Index, Florida Solar Energy Center, Philip Fairey

FSEC Energy Research Center®

The EnergyGauge HERS software tool is used to examine the 2012 IECC Standard Reference Design (IECC SRD) configuration for three-bedroom, one-story 2000 ft² and three-bedroom, two-story 2,400 ft² single-family homes in sixteen representative U.S. cities. The energy use of the 2012 SRD homes is compared against the energy use of homes complying with the 2015 IECC using the ERI compliance method. HERS simulations for each home are conducted for both a best case home orientation and a worst case home orientation. Improvements to the 2012 IECC SRD homes are made such that the HERS Index for the homes …

A Comparison Of Homes Built To The 2009 And 1984 Florida Energy Codes, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

The Florida Solar Energy Center conducted research into the effectiveness of the Florida energy code to reduce energy use in residential buildings. FSEC examined two groups of homes: those built to the 1984 energy code (June 1,1984-1985) and those built to the 2007 with 2009 supplement energy code (March 1, 2009-2010). This report discusses data collection methods, analysis and results that focus on comparisons of measured energy use and house characteristics between both code periods.

Final Technical Report (2nd Revision) Arra: Florida Energy Code Compliance Train-The-Trainer Program, Florida Solar Energy Center, Jeffrey Sonne

Field testing was completed in 40 central Florida homes (built after March 1, 2002) to examine compliance with the balanced return air, duct leakage, and combustion/dilution air requirements of the Florida Mechanical Code. A course titled Complying with Duct System Requirements of the Florida Energy Code …

Assessment Of Infiltration Practices In The Florida Energy Code, Florida Solar Energy Center, James Cummings

FSEC Energy Research Center®

The Florida Department of Community Affairs has contracted with the Florida Solar Energy Center (FSEC) to review the current infiltration practices of the Florida Energy Code to determine, based on analysis of the best currently available infiltration data, whether there is need for three infiltration practices, and to make recommendations of what "point multipliers" should be applied to the infiltration practice(s). An advisory committee of industry, utility, and research representatives was formed to review the findings of the project and express opinions about the form the infiltration practices should take. This committee met twice, reviewed each of the reports produced …
