Notice of Intent: Building America Industry Partnership for High-Performance Housing Innovation

EERE intends to issue, on behalf of the Building Technologies Office, a funding opportunity announcement (FOA) entitled, "Building America Industry Partnerships for High-Performance Housing Innovation.” This FOA is expected to be posted to EERE Exchange in late 2014.

Selected teams will conduct applied R&D in real-world houses to demonstrate market-relevant strategies that will lead to 40% energy savings in existing homes by 2030 and 50% savings in new homes (over International Energy Conservation Code 2009) by 2025.

New Building America Code Compliance Brief—Floor Insulation

The Building America Solution Center has added a new Code Compliance Brief to its collection of resources that address barriers to building innovations from codes and standards. This new brief addresses floor insulation and offers another option for insulating floors that is now defined in the 2015 IECC/IRC. See information for floors above unconditioned basement, vented crawlspace, cantilevered floors; and floors above a garage.

Building America Code Compliance Briefs aim to facilitate the conversation between builders, installers, and code officials when an innovative product or technique is used in the field. This process will help to expedite code compliance for innovations at the time of plan review and field inspection, avoiding compliance issues and costly delays. Code Compliance Briefs are also available for double wall framing and bathroom fans.

Building America Webinar—October 23: High-Performance Space Conditioning Systems: Part I

Building America brings you free monthly webinars highlighting the latest advances in residential building technologies and practices, presented by Building America research team experts. Please join us for the October webinar:

Date/Time: October 23, 2014; 3-4:30 p.m. EDT
Description: The webinar will focus on strategies to improve the performance of HVAC systems for low-load homes and home performance retrofits. Presenters and specific topics for this webinar:

  • Andrew Poerschke, IBACOS, presenting HVAC for Low-load Homes and Thermal Comfort. The presentation will focus on what is “simple” when it comes to space conditioning, and will also discuss how different options maintain comfort, what will and won’t work, and what you should discuss with clients looking for simple and potentially lower cost solutions to a single furnace and ducts to each room.
  • Kohta Ueno, Building Science Corporation (BSC), presenting Long-Term Performance of Mini-Splits in Cold Climate Housing. Kohta will discuss BSC’s research on ductless heat pumps versus mini-splits being used in high-performance (high-R value enclosure/low air leakage) houses, often configured as a simplified distribution system (one heat source per floor).
  • Larry Brand, Partnership for Advanced Residential Retrofit, presenting Natural Gas Furnace Improvements. This presentation will provide information from manufacturers and other industry experts on how to get the best performance from natural gas furnaces, results of lab testing under several conditions representative of challenging installations, and a comparison between efficiency levels in the field and in the lab for nine furnaces that were removed from the field and replaced at end of life.

October 2014 Residential Successes: 2014 Housing Innovation Awards

This month’s residential successes showcase two examples of 2014 Housing Innovation Awards winners:

New Construction: Affordable Grand Winner: TC Legend Homes, Bellingham, Washington
This house features 6-inch structural insulated panel (SIP) walls, a 10-inch SIP roof, and insulated concrete form foundation walls with R-20 high-density rigid expanded polystyrene foam under the slab. A single ductless heat pump heats and cools the home, which also gets passive solar heating from south-facing triple-pane windows that heat a concrete slab floor plus a connected greenhouse.

Retrofit: Green Extreme Homes and Carl Franklin Homes
This is the first retrofit home certified to the DOE Zero Energy Ready home requirements. The 60-year-old, three-bedroom ranch home is expected to save its homeowner more than $1,000 per year in utility bills compared to a home built to the current 2009 International Energy Conservation Code.

Building America in the News

Here are recent Building America-related articles in popular trade publications:

New Publications from Building America

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 are 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 our most recent publications:

Measure Guideline: Guide to Attic Air-Sealing
This guide by Building Science Corporation provides information and recommendations for the preparation work necessary for adding attic insulation, and is intended for home remodelers, builders, insulation contractors, mechanical contractors, and general contractors. Even though the purpose of this guide is to save energy, health, safety, and durability should not be compromised by energy efficiency. Accordingly, combustion safety and ventilation for indoor air quality are addressed first; durability and attic ventilation follow. Finally, to maximize energy savings, air-sealing is completed before installation is installed.

Technology Solutions Case Study: Excavationless: Exterior-Side Foundation Insulation for Existing Homes
In this project, NorthernSTAR Building America Partnership describes an innovative, minimally invasive foundation insulation upgrade technique on an existing home that uses hydrovac excavation technology combined with a liquid insulating foam. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

Hydronic Heating Retrofits for Low-Rise Multifamily Buildings
Building America team Advanced Residential Integrated Energy Solutions Collaborative partnered with NeighborWorks America affiliate Homeowners' Rehab Inc. of Cambridge, Massachusetts, to study improvements to the central hydronic heating system in one of the nonprofit's housing developments. The heating controls in the three-building, 42-unit Columbia Cambridge Alliance for Spanish Tenants housing development were upgraded. Utility bill analysis shows that post-retrofit weather-normalized heating energy use was reduced by 10%-31% (average of 19%). Indoor temperature cutoff reduced boiler runtime (and therefore heating fuel consumption) by 28% in the one building in which it was implemented.
