New Buildings Institute urges you to carefully consider the six ballot items listed below. Votes on these items will help determine for millions and millions of square feet constructed under this three-year cycle whether the commercial building sector can contribute, or not, to the nation's energy and climate goals through the 21st century.
Testing of Air Barrier Compliance
CE105 - As Modified by PC3/PC5
Reducing the leakage of air through the building envelope is one of the critical steps the IECC can make this cycle. CE105 was written by the US Department of Energy to based on their analysis to ensure their cost-effective rules are applied to air barrier testing to the minimum building sizes according the particular climatic conditions.
Inspection and Verification of Air Barrier Compliance
CE107 - As Submitted
Where CE105 works to improve the air barrier performance of buildings through wider use of building testing, CE107 improves the air barrier performance in buildings that are not tested through requiring critical inspections and verification of the air barrier installation.
Minimum Efficacy In Agricultural Lighting
CE200 - As Modified by Public Comment
Agricultural lighting is the fastest growing energy application in many areas across the country but is completely exempt from the 2015 IECC. CE200 AMPC sets minimum efficacy levels thereby minimizing the use of the least efficient lighting equipment in these energy-intensive operations, sometimes with power densities exceeding data centers.
Efficient Showerheads
CE175 (Part 1 and Part 2) - As Submitted
Hot water usage is the dominant energy demand in some buildings with dwelling units. The IECC regulates hot water equipment, plumbing layouts, and now needs to tackle the faucets and showerheads. CE175 requires that the widely available Water Sense fixtures be used.
Electric Load Segregation
CE225 - As Modified by Committee
Since segregating electric loads for future monitoring is most practical at time of new construction, CE225 requires that buildings greater than 25000 square foot split the electric load into 5 major end-use categories so that they can be effectively and inexpensively monitored in the future.
Solar Energy Tradeoff with Efficiency
CE251 - As Modified by Committee
Under current IECC language, the commercial modeling path allows projects to subtract all of the generated renewable energy from the project energy budget. CE251 would limit that tradeoff to 5% of the total load, instead of 100%.
