Student Design Competition for Zero Energy Ready Homes: A Win-Win for Students, Industry, Environment
Two teams tied as Grand Award winners: Ryerson University from Toronto, Ontario, for the "Urban Harvest" design, and the combined student team from Onondaga Community College, SUNY College of Environmental Science and Forestry, and Syracuse University, all of Syracuse, New York, for the "Montage Builders Northern Forest" project. "Applying the building science and design principles we learned in the classroom to a real-world project was an incredible learning experience," said Michelle Tinner, member of the Montage Builders team. "Also, as our team came together from several schools, a key lesson for us was learning how to collaborate to achieve the best design solution within the parameters of the competition." Read details about the winners in several categories and see photos from the competition at the U.S. Department of Energy's news release and blog.
The U.S. Department of Energy's (DOE) Housing Innovation Awards recognize the very best in innovation on the path to zero energy ready homes. The 2014 Housing Innovation Awards ceremony will be held on September 23, 2014, at EEBA's Excellence in Building Conference in St. Louis, MO.

High Performance Building Enclosures: Part I, Existing Homes
Date/Time: May 21, 2014; 3:00 PM EDT
Description: The webinar will focus on specific Building America projects that have implemented technical solutions to retrofit building enclosures to improve energy and durability. Presenters will answer tough questions, such as:
- How can builders deal with increasing exterior foundation insulation without an excavator?
- What strategies can be used to improve energy performance of building envelopes while dealing with issues such as ice damming during exterior "overcoat" insulation retrofits?
- How can deep energy retrofits be conducted with spray foam strategies; what works and what doesn't?
- Tom Schirber (NorthernSTAR Building America Partnership), providing strategies for retrofitting exterior foundation insulation without an excavator.
- Steve Schirber (NorthernSTAR), presenting "Project Overcoat, A Robust Energy Upgrade for 1 1/2-story Homes." This presentation will explain specific techniques that ensure a low-risk, high performance overcoat upgrade on existing homes.
- Anatasia Herk (IBACOS), presenting strategies for exterior insulation without removing old cladding. This presentation will focus on a project between IBACOS and GreenHomes America that studied different strategies for exterior wall insulation in Syracuse, NY.
This Month's Residential Successes: Pacific Northwest New Construction and Retrofit
Each month, Building America highlights examples of high performance home building for new and existing homes across the nation. The May 2014 successes hail from the Pacific Northwest area and show how Building America teams and builders tackle specific challenges in the marine climate zone.
- Technology Solutions for New Manufactured Homes: The Building America Partnership for Improved Residential Construction team worked with manufacturers in Idaho, Oregon, and Washington to prototype and assess a package of readily available, cost-effective, high performance building assemblies and mechanical systems not commonly deployed in the manufactured home sector.
- Deep Energy Retrofit of 1910 House: This historic home had no insulation, an unfinished basement, old appliances and air leaks everywhere when purchased by its current owner in 2010. The owner performed a full deep energy retrofit, including air sealing and insulating exterior walls and attic and installed new, efficient appliances, achieving a HERS score of 68.

The Building America Publications Library offers an extensive collection of technical reports, measure guidelines, case studies, and other resources to help you boost energy efficiency in new and existing homes. On the library page, you can subscribe to the RSS feed that delivers reports as they as published. Also, the Building America Solution Center links you to expert building science and energy efficiency information based on Building America research results. Here are samples of some of our most recent publications:
Measure Guideline: Combustion Safety for Natural Draft Appliances Using Indoor Air
This measure guideline describes how to assess and carry out the combustion safety procedures for appliances and heating equipment that uses indoor air for combustion in low-rise residential buildings. Only appliances installed in the living space, or in an area freely communicating with the living space, vented alone or in tandem with another appliance, are considered here. This document is for inspectors, auditors, and technicians working in homes where energy upgrades are being conducted, whether or not air infiltration control is included in the package of measures being applied.
Technology Solutions Case Study: Impact of Infiltration and Ventilation on Measured Space Conditioning Energy and Moisture Levels in the Hot-Humid Climate
Air infiltration and ventilation in residential buildings is a very large part of the heating loads, but empirical data regarding the impact on space cooling have been lacking. Moreover, there have been few data on how building tightness might relate to building interior moisture levels in homes in a hot and humid climate. To address this need, BA-PIRC conducted research to assess the moisture and cooling load impacts of airtightness and mechanical ventilation in two identical laboratory homes in the hot-humid climate over the cooling season.
Advanced Envelope Research for Factory Built Housing, Phase 3—Whole-House Prototyping
The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective envelope designs that can be effectively integrated into the plant production process while meeting the thermal requirements of the 2012 IECC standards. This work is part of a multiphase effort; this report describes Phase 3, which was completed in two stages and continued the design development effort, exploring and evaluating a range or methods for applying continuous insulation to factory built homes. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing.
