The Iowa Nest Residence was featured on the cover, and in a feature article, of the May/June 2020 issue of ICF Builder Magazine. The issue focuses on green building, energy efficiency, and Passive House projects.
The Nest Residence won the 2020 ICF Builder Award in the category of Small Residential. The annual project-of-the-year competition is widely regarded as the biggest event in the Insulated Concrete Forms (ICF) industry.
The 13th edition of Mechanical and Electrical Equipment for Buildings (AKA “MEEB”) has just been published by Wiley. Chapter 1 on Design Process prominently features the Iowa Nest Residence as an exemplar of high-performance design — incorporating much of the material that has been discussed in detail on this blog.
Below is the slideshow I presented on April 20, 2017 to the Iowa Building Enclosure Council, and to a sustainable construction class from Hawkeye Community College.
The version below is slightly edited to make it easier to follow online. (I tend to avoid text in my presentations, which can make them difficult to follow without accompaniment.)
We were pleased to host the Iowa chapter of the Building Enclosure Council (BEC) for a house tour and presentation, as well as a sustainable construction class from Hawkeye College. Many thanks to everyone who came out — including for the many excellent questions and kind words about the house.
This webinar from December 2015 provides an overview of the design processes and analyses that were used to set the project on track toward Net Zero Energy during Conceptual and Schematic Design. The studies include “simple box” energy modeling to determine the best passive design measures, comparison of design options, analysis of shading strategies, and optimization of envelope parameters like R-values and glazing. I used a variety of tools including Climate Consultant and the CBE Thermal Comfort Tool — but mostly I used Sefaira Architecture. (Full disclosure: I worked for Sefaira for nearly five years; that’s where this webinar comes from originally.)
