The envelope backstop was introduced by policymakers to limit how far building enclosure thermal performance can stray from the envelope prescriptive requirements.
The campaign encourages implementation of the most up-to-date energy codes to reduce greenhouse gas emissions, increase energy efficiency, and enhance resiliency and safety.
The requirements in green standards alone, such as LEED, Green Globes and IgCC may lack comprehensive measures to address resiliency related to the long-term performance of the building enclosure
When it comes to operational energy efficiency, the building design and construction industry continuously raises the ceiling through myriad collective avenues including the increased stringency of volunteer rating systems, monitoring-based commissioning, verified zero energy buildings, and much more
Understanding the energy code requirements and how to properly calculate the fenestration U-factors is an important skill to develop to inform the building-enclosure design
The energy efficiency of buildings is the main goal of these code changes, with the hope that the efficiency of all buildings (residential and commercial) will rise by about 10 percent
