The U.S. Department of Energy?s (DOE?s) Building Technologies Office (BTO), within the Department?s Office of Energy Efficiency and Renewable Energy (EERE), is developing a new research-to-market plan, focused on substantially solving three key technical challenges in the next five years. Successfully meeting these critical challenges will help transform the market for new zero energy ready homes and will lead to significant improvement in the energy efficiency and performance of existing homes across the United States (U.S.). As part of this new research-to-market plan, the BTO?s Building America program seeks feedback on three (3) draft integrated technology-to-market roadmaps that highlight proposed Building America program goals and objectives for each key technical challenge: A. High Performance, Moisture Managed Envelope Systems B. Optimal Comfort Systems for Low Load Homes C. Optimal Ventilation Systems and Indoor Air Quality (IAQ) Solutions for Low Load Homes Feedback solicited from this RFI related to these draft technology-to-market roadmaps will be used in part to help plan and develop future Building America Funding Opportunity Announcements (FOA?s), as the Building America program works to meet its 2030 goals stated below. This is solely a request for information and not a FOA; therefore, DOE is not accepting applications at this time. DOE will not respond to questions related to this RFI. The full RFI document can be accessed under the "FOA Documents" heading below. Responses to this RFI must be submitted electronically to BuildingAmericaRFI@ee.doe.gov no later than 5:00pm (ET) on April 30, 2015. Responses must be provided as attachments to an email. The purpose of this Request for Information (RFI) is to gather feedback from stakeholders prior to DOE potentially issuing a Funding Opportunity Announcement (FOA). This RFI is not a FOA; therefore, DOE is not accepting applications at this time. All responses to this RFI must be provided as an attachment (in Microsoft Word format) to an e-mail message addressed to [enter mailbox]@go.doe.gov. Responses must be received no later than 11:59PM EDT on [enter date]. The full content of the announcement can be found on the EERE Exchange website at https://eere-exchange.energy.gov.
