This test house is projected to achieve 38% source energy savings relative to the Building America House Simulation Protocols (Hendron and Engebrecht 2010) and to achieve 51% source energy savings with the installed 2.0-kW photovoltaic (PV) system. The project included improvement...

IBACOS anticipates that houses achieving 50% whole-house source energy savings with respect to the Building America 2010 Benchmark (Hendron and Engebrecht 2010) will be “low load.” Low load is defined by IBACOS as a house with a thermal enclosure that yields a maximum space...

The PV-GEMS whole building retrofit features a small, grid-independent photovoltaic (PV) system designed to partially power a high efficiency heat pump water heater, which replaces the home’s existing water heater, and a high efficiency minisplit heat pump, acting as an enhancem...

Energy intensity data and documentation published by the U.S. DOE's office of Energy Efficiency and Renewable Energy (EERE). Energy intensity is defined as: amount of energy used in producing a given level of output or activity; expressed as energy per unit of output. This is the ...

Building energy simulations can be used to predict a building’s interior conditions, along with the energy use associated with keeping these conditions comfortable. These models simulate the loads on the building (e.g., internal gains, envelope heat transfer), determine the op...

Domestic hot water (DHW) is the second-largest energy end use in U.S. buildings; it is exceeded only by space conditioning. In this study, the U.S. Department of Energy’s Building America research team Advanced Research Integrated Energy Solutions installed and tested two types...

This spreadsheet allows the user to calculate parameters relevant to techno-economic performance of a two-step absorption process to transport low temperature geothermal heat some distance (1-20 miles) for use in building air conditioning. The parameters included are (1) energy de...

Wonderland Development has constructed a new “near zero energy” row home design in North Boulder consisting of 9 units: one 5-plex and two duplexes. NREL has performed short-term tests and installed long-term monitoring equipment in three of these units. Two of these units use...
