Advanced Building Equipment Technologies


c.       Advanced Building Equipment Technologies

This subtopic seeks proposals for the design of new energy efficient advanced building equipment technologies.


The ABC Initiative focuses on several key areas for building equipment technologies. HVAC and water heating technologies influence the design of new buildings and retrofit opportunities, and by taking these technologies into consideration will allow DOE to expand the ABC R&D portfolio beyond existing state-of-the art integrated heat pump (IHP) solutions. DOE is particularly interested in proposals that leverage previous building equipment R&D to make solutions that are relevant to ABC. For example, IHP technology and multi-functional space-conditioning unit with water heating function can facilitate whole-building, deep energy retrofits in the residential sector by integrating the solution into the building itself, like variable refrigerant flow systems. These technologies lead to significant energy savings (greater than 50%) by recovering condensing waste heat in the cooling season and providing dedicated or desuperheating heat pump water heating. This type of heat exchanger utilizes the high temperature of the superheated refrigerant gas to heat water. For more information, applicants should read BTO’s Energy Savings Potential and RD&D Opportunities for Non-Vapor-Compression HVAC Technologies report [1].


This subtopic seeks proposals in the following specific areas:

·         Energy and work recovery technologies that significantly advance the state-of-the-art for HVAC and water heating equipment. DOE is particularly interested in technologies that do not rely on passive and expensive materials but could use active (non-vapor compression) technology to transfer waste heat for preheating use. Applicants must demonstrate how the technologies could be incorporated into equipment design.

·         New approaches, technologies, and concepts that address air and water distribution systems with improved energy efficiency and occupant comfort.


Given the wide range of ABC building equipment technologies suitable for this subtopic, specific cost targets are not defined in the subtopic; however, applications must outline expected costs of the proposed design, providing analysis to support claims made. Applicants should also consider system approaches at the whole building level.


Applications must demonstrate greater than or equal to 30 percent energy efficiency as compared to state-of-the-art or Energy Star equipment, little to no increase in physical size, or little to no increase in difficulty to clean to maintain as-new performance as compared to state-of-the-art or Energy Star equipment, as well as a payback period less than or equal to 5 years.


Examples of product or technology advancement include energy savings in HVAC and water applications, including but not limited to general discrete HVAC and water heating equipment, increased productivity, enhanced comfort, and reduced environmental impacts.
