Houston gets ready for a leap...

Author: Kapil UpadhyayaAuthor:

The City is leaping forward in a commendable way – using its Building Energy Code. Do you ask, ‘What is happening with Houston Commercial Energy Code?’ Well,…

It’s changing,…

For 5 years now, City of Houston has followed ASHRAE90.1-2007 or 2009 IECC. Almost 3 years after it was released, ASHRAE90.1-2013 would be adopted by the City as the new Energy Code. This move comes after a key change made in State Policy in October 2015, when the State of Texas adopted 2015 IECC for all Commercial buildings. For a few years now, all State-funded buildings had been meeting ASHRAE90.1-2010. But the change to ASHRAE90.1-2013 puts Texas up, front and center among about 10 states that are leading the charge on building-energy efficiency.

…it’s 22% more efficient!,…

This percentage compares Predicted EUI for ASHRAE90.1-2010 to that of ASHRAE90.1-2013. It is based on energy models used by Department of Energy to assess impact of energy-codes. It is an average across 16 building types in 15 climate zones. In other words, it casts a wide net to capture the effect of ASHRAE90.1. Consider for example the difference between the following: an Office building with a 90.1-2013 EUI of 29.4 kBtu/sf versus a Fast-Food restaurant with an EUI of 576.4 kBtu/sf. Nevertheless, the Predicted EUI is a useful measure to compare codes.
