Development of a Residential Integrated Ventilation Controller

Description: The goal of this study was to develop a Residential Integrated Ventilation Controller (RIVEC) to reduce the energy impact of required mechanical ventilation by 20percent, maintain or improve indoor air quality and provide demand response benefits. This represents potential energy savings of about 140 GWh of electricity and 83 million therms of natural gas as well as proportional peak savings in California. The RIVEC controller is intended to meet the 2008 Title 24 requirements for residential v… more

Ozone Reductions Using Residential Building Envelopes

Description: Ozone is an air pollutant with that can have significant health effects and a significant source of ozone in some regions of California is outdoor air. Because people spend the vast majority of their time indoors, reduction in indoor levels of ozone could lead to improved health for many California residents. Ozone is removed from indoor air by surface reactions and can also be filtered by building envelopes. The magnitude of the envelope impact depends on the specific building materials that t… more

Improving Gas Furnace Performance: A Field and Laboratory Study at End of Life

Description: Natural gas furnaces are rated for efficiency using the U.S. Department of Energy (DOE) annual fuel utilization efficiency (AFUE) test standard under controlled laboratory test conditions. In the home, these furnaces are then installed under conditions that can vary significantly from the standard, require adjustment by the installing contractor to adapt to field conditions, may or may not be inspected over their useful lifetimes, and can operate with little maintenance over a 30-year period or… more

Model Validation and Testing: The Methodological Foundation of ASHRAE Standard 140; Preprint

Description: Ideally, whole-building energy simulation programs model all aspects of a building that influence energy use and thermal and visual comfort for the occupants. An essential component of the development of such computer simulation models is a rigorous program of validation and testing. This paper describes a methodology to evaluate the accuracy of whole-building energy simulation programs. The methodology is also used to identify and diagnose differences in simulation predictions that may be caus… more

Improving the Field Performance of Natural Gas Furnaces, Chicago, Illinois (Fact Sheet)

Description: The objective of this project is to examine the impact that common installation practices and age-induced equipment degradation may have on the installed performance of natural gas furnaces, as measured by steady-state efficiency and AFUE. PARR identified twelve furnaces of various ages and efficiencies that were operating in residential homes in the Des Moines Iowa metropolitan area and worked with a local HVAC contractor to retrieve them and test them for steady-state efficiency and AFUE in t… more

Passive Room-to-Room Air Transfer, Fresno, California (Fact Sheet)

Description: Field testing was performed in a retrofit unoccupied test house in Fresno, California. Three air-based heating, ventilation, and air conditioning (HVAC) distribution systems - a typical airflow ducted system to the bedrooms, a low airflow ducted system to the bedrooms, and a system with no ductwork to the bedrooms - were evaluated during heating, cooling, and midseason conditions. The relative ability of each of the three systems was assessed with respect to relevant Air Conditioning Contractor… more
