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 …

Maximum Energy Efficiency Cost Effectiveness In New Home Construction, Florida Solar Energy Center, Philip Fairey

FSEC Energy Research Center®

EnergyGauge® USA (v.4.0.00) is used to examine the cost effectiveness of high performance homes that are improved to significantly exceed the minimum requirements of the 2015 IECC. The objective of the study is to determine the maximum level of energy efficiency that can be considered cost effective to the consumer. For these purposes, it is the cost effectiveness of the entire package of measures that is considered by the analysis rather than the cost effectiveness of individual measures. Optimization and rank ordering of the individual improvement measures in the package is not considered by the analysis.
