Article
The energy performance of residential buildings is closely correlated with occupants’ behavior and their schedules. Moreover, the energy consumption of heating, ventilation, and air conditioning (HVAC) systems, which are by far the biggest contributor to energy consumption in residential buildings, is controlled by the presence or absence of occupa...

The COVID-19 pandemic and its associated lockdown have caused significant changes in lifestyle all around the globe. The combined effect of business and school closures as well as restrictions on travel during this period introduced unprecedented changes in occupancy presence and behavioral patterns in buildings. Electricity consumption in resident...
Conference Paper
Full-text available
Residential buildings consume a significant portion of energy and electricity in the U.S. The residential housing stock in rural areas of the U.S. is generally more likely to be older and less energy-efficient than those homes built in more urban areas. Efforts to improve the energy efficiency of such residential buildings, include benefits such as...

Full-text available
Building cooling loads are driven by heat gains through enclosures. This research identifies possible ways of reducing the building cooling loads through vegetative shading. Vegetative shading reduces heat gains by blocking radiation and by evaporative air cooling. Few measured data exist, so we gathered thermal data from a vegetative wall grown in...
Conference Paper
Full-text available
Urban vegetation is known to be effective in mitigating the Urban Heat Island (UHI) effect and reducing building energy use, specifically that associated with cooling. However, to quantify urban trees’ cooling effect, the influence of their characteristics on cooling effectiveness and the corresponding building energy use needs to be assessed quant...
Article
We deploy a fully coupled thermo-fluidic finite element approach to simulating natural ventilation in a sustainably designed building with complex geometry. The ‘interlock house’ uses building design for climate control instead of mechanical means (such as air conditioning). Therefore, accurately modeling the natural ventilation flows is crucial to...
Article

Dense urban areas use up more energy, water and food resources than they can produce themselves, forcing them to rely on external sources. But a team of researchers is imagining bold new ways to make Midwestern cities more self-reliant. The Sustainable Cities Research Team recently received a $2.5 million grant from the National Science Foundation to develop a framework for analysis of food, energy and water systems for greater Des Moines, which includes the city and the surrounding six-county area, and to formulate scenarios that could result in a more sustainable city. The team includes scientists from a wide range of disciplines at Iowa State University, the University of Northern Iowa and University of Texas at Arlington. The group intends for its results to inform decisions about food production, energy use, environmental outcomes and related policies that would apply to a large number of cities in rain-fed climates similar to Des Moines. Their innovative approach could help cities conserve building and transportation energy, reduce environmental impacts and improve city sustainability.
