Project researches how thermal energy is measured in buildings
The goal of The Thermal Metric project is to improve how thermal energy is measured in buildings. Led by Building Science Corp. researchers, the project is supported by a group of insulation manufacturers.
Temperature-dependent thermal conductivity effects are less well-understood by the construction industry, the group notes. Research conducted by manufacturers and independent researchers has established that insulation performs differently at different mean temperatures. Further research is required to assess the impact of temperature effects on annual energy usage. These data can be used to improve building codes and computer-based energy models.
Other factors, such as air flow interactions, are just beginning to be researched in greater detail, the group says. Air flow is known to have a significant impact on building energy use. Standard hot box methods do not account for air flow interactions. The Thermal Metric project was designed in part to address this limitation.
