The University of Florida will develop a technology for compact, low-cost combined water heating, dehumidification, and space cooling. This technology has the potential to save 480 TBtu/year in water heating and an additional 135 TBtu/year by reducing the air conditioning load.

Hudson Fisonic will develop, design, manufacture, and install FDs for space heating and domestic hot water at the Woolworth building (57 stories, 900k ft2). The performance of the FD will be monitored for 12 months to determine the steam and potable water savings from use of this technology. Hudson Fisonic will start the commercialization of the FD technology by engaging the manufacturer - Division LLC Corporation, located in Long Island City, New York, in fabricating and preparing the necessary facilities and equipment for commercial manufacturing of FDs

Heating water for commercial is identified in the 7th Power Plan as desired measures. The goal of this project is to fund the design, installation, commissioning and warranty of a large commercial heat pump water heater (HPWHs) as an Emerging Technology Field Test. BPA will award fund utility grants to design, install and commissioning the unit, meter energy usage and provide data to BPA for further analyses. Each utility will also provide results regarding the design, installation, and commissioning of the unit which will be shared publically

The Contractor seeks to baseline test, install, and evaluate the performance of a 21kW micro-CHP system, that provides hot water and power as a packaged unit, at (2) Host Sites in NY. The proposed System shall feature a synchronous generator and black-start capability. The goal of the project is to provide manufacturers, building owners, and installers information regarding the deployment of micro-CHP systems, in order to promote a sustainable market for micro-CHP systems in NY. Once the Host Sites are selected, the System shall be independently tested and configured and the Host Sites shall be prepared for the proper integration of the Systems on-site. The Systems shall be installed and monitored for 12 months before developing a report to disseminate to the stakeholders.

Design guidelines have helped accelerate the deployment strategies for central hot water systems in multifamily buildings through the Pacific Northwest. This project will deliver two design guidelines for multifamily hot water recirculation loops and central heat pump hot water systems for future use by architects, engineers, contractors and developers by distilling the best practices and findings from recently completed research. Each guideline will present the operating principles, recommended design choices, and give examples where appropriate.

This project proposes to design, pilot, and verify air-source, CO2 heat pump water heaters for domestic water heating in small-scale multifamily buildings. A second, significant goal of the project is to enable technology transfer.

Ecotope, in partnership with Vulcan Real Estate and Seattle City Light proposes to design, pilot and verify a heat pump water heating system for large multifamily buildings using the building sewage as a heat source. The waste water heat pump (WWHP) will recover waste heat streams from the building and heat water for domestic use at extremely high performance levels. The system will be built in a large multifamily building with approximately 400 apartment units. The project team will conduct a feasibility study of the system concept and a numerical model to predict the best equipment sizing and control algorithms. With the feasibility demonstrated the team will move on to full system design in a multifamily building. The team will write a measurement plan to monitor the energy use of the system. The team will commission the system, optimize its operation and prepare a set of design guidelines to be used throughout the engineering community.
