"This principle can be utilized with heat storage if the melting point of the phase-change material is about room temperature."
This report focuses on building envelopes that have been enhanced with phase change materials, which can simultaneously reduce total cooling loads and shift peak-hour loads.
This paper assesses the opportunities of utilizing Phase Change Materials (PCMs) in building enclosure systems to improve energy performance and thermal comfort in buildings.
"Why choose continuous insulation and air barriers? The biggest problem with many insulated buildings involves thermal bridging. These occur when poor thermal insulator materials meet, creating the path of least resistance for heat to pass through."
How to determine the amount of continuous insulation required by codes, while still retarding water vapor according to climate zone locations
"While ASHRAE 90.1 has been pushing continuous insulation (CI) for the past decade, the building codes are catching on. And now that the U.S. Department of Energy (DoE) has mandated all states to adopt a commercial building energy code that meets or exceeds ASHRAE Standard 90.1-2010, CI specifications are really being cast into the spotlight."
You know what R-value is, but how do they figure it out? And is it really a reliable measure of insulation performance?
"Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils."
"Building façades directly influence heating and cooling loads and indirectly influence lighting loads when daylighting is considered, and are therefore a major determinant of annual energy use and peak electric demand. Façades also significantly influence occupant comfort and satisfaction, making the design optimization challenge more complex than many other building systems."
