Zone 5

A "Plug-n-Play" Air Delivery System for Low-Load Homes and Evaluation of a Residential Thermal Comfort Rating Method

IBACOS will investigate a simplified residential air delivery system to resolve comfort issues reported in low-load, production-built homes. This project could result in state-of-the-art comfort distribution systems, as well as a thermal comfort metric that helps builders and HVAC contractors measure and communicate the value of improved comfort delivery systems.

Monitoring of Unvented Roofs with Diffusion Vents and Interior Vapor Control in a Cold Climate

Building Science Corporation and partners will evaluate the use of a vapor control membrane, or diffusion vent, which could substantially reduce the risk of moisture issues in roof assemblies with fibrous insulation. This project will field test this solution in a cold climate new construction test house over three years, and will also test the approach in a high impact existing home weatherization application to be determined through stakeholder engagement.

Performance of Thermal Storage Retrofit

The Wild Center will refine the analysis to determine the optimum thermal storage volume with respect to energy savings, cost, and available area. The preliminary analysis shows that 1,700 gallons would yield improved performance, however they do not have the space to install a single tank with this volume. Instead, they will install two tanks each with half the identified volume. Clarkson University will build upon their previous studies of the boiler and extensively monitor the performance benefits associated with the thermal storage. They will capture data of the course of two years which will provide a comprehensive data set. They will also conduct an evaluation according to the ASHRAE 155P test method. The Wild Center will incorporate the data into their exhibits, allowing visitors to better understand biomass combustion.

Physics-based Interval Data Models to Automate and Scale Home Energy Performance Evaluations

Fraunhofer USA Center for Sustainable Energy Systems Inc. and partners will develop models that use communicating thermostat data and interval electricity and gas data to remotely identify homes with significant energy savings opportunities. The tool will identify the top 20% of homes with the greatest potential for energy savings from insulation, air sealing, and/or heating system upgrades, reducing the number of unnecessary energy audits.

Research and develop a Flame-assisted Fuel Cell for integration into a residential-sized boiler.

Syracuse University will fabricate and laboratory test a stack of Flame-assisted Fuel Cells (FFCs), which can generate electricity from the flame of fuel combustion. The research is intended to analyze the performance of the FFCs as well as their ability to undergo extensive thermal cycling. Data will be collected to quantify the open circuit voltage, power density, current density, and stack impedance compared to calculated values. Syracuse University will conduct research to determine if there are any opportunities to improve on material construction. The project will conclude with a market analysis and economic assessment of applications for the technology

Rooms Containing Fuel-Burning Appliances - Code Compliance Brief

An entirely new section in the 2015 IECC/IRC regarding fuel-burning appliances basically requires the appliance to be isolated from the building thermal envelope, located either outside or within a separate room if the fuel-burning appliance is supplied by open combustion air ducts. This brief provides an overview of the requirements and further details of approving the actual "room".

Total Charge Management: Advanced Charge Management for Renewable Integration

This project will explore the benefits and opportunities of Total Charge Management, where electric vehicle charging is managed across multiple charging events to maximize vehicle load flexibility. The project will test how flexible electric vehicle load can be if managed across a driver's daily or weekly charge events. This flexibility will utilize several pricing mechanisms to estimate the benefits of the Total Charge Management approach. The research will develop and evaluate advanced vehicle telematics for utilities and grid operators to align vehicle battery status, driver mobility needs and grid conditions. Collaboration between the grid and the driver can yield a charging load profile that minimizes energy costs by aligning daily and weekly charging events to best meet grid needs.
