Mass Walls and Required Insulation R-Value – Energy Code

by Sean O'Hara, AIA, LEED AP July 26, 2019

Note: This is based on the 2006 IECC and this section changes in the 2009 code, so its always important to verify which code is adopted. Mass walls are walls that provide energy efficiency through mass rather than insulative value. The mass allows them to […]

Denver Building Code & Energy Calculations

by Sean O'Hara, AIA, LEED AP November 16, 2018

Beth Freeman called the Denver Building Department to ask about their new requirements for energy calculations on single family residences. We haven’t had to submit them in the past, but we’d heard that some builders had. The word from Denver is that you do not […]

The Building Envelope and Energy Savings

by EVstudio AEP August 28, 2017

The building envelope consists of three main elements: the roof, the walls, and the foundation. The main concerns we have for these building elements are protecting the interior of the home from weather and other environmental issues, slowing the transmission of heat and controlling light, […]

Climate Zones in Colorado and the International Energy Conservation Code – Insulation R Values

by Sean O'Hara, AIA, LEED AP May 3, 2009

The International Energy Conservation Code is increasingly the standard energy code that municipalities are adopting. In prescribes insulation (r-value) requirements for both residential and commercial buildings. In order to determine what your required insulation values are, you must first determine which of the climate zones […]
