Title: Heat Flow Meter for thermal measurements

General Statement of Need:

The Heat Transfer and Alternative Energy Systems (HTAES) Group within the Energy and Environment Division of the National Institute of Standards and Technology (NIST) contributes to the advancement of measurement science needed to achieve net-zero energy, high-performance buildings. One key component to achieving net-zero energy is advanced building energy technologies, especially thermal insulation for building envelope system. Accordingly, the focus area for the thermal insulation project within the group is to improve the tools used for measuring and evaluating thermal properties of various insulation materials and building envelopes. Understanding the thermal properties of various innovative thermal insulation and building envelope materials at various size scales provides important data to achieve high-performance buildings. A Heat Flow Meter (HFM) is an apparatus that is used for measuring thermal conductivity of insulation materials and is considered an important industry standard tool for thermal measurements along with other equipment such as the Guarded Hot Plate. The HTAES group will utilize the requested instrument for investigating the thermal properties of various thermal insulations, and phase change materials. The contact force measurement capability of the requested HFM will provide a similar test condition with NIST GHP instruments and will therefore complement other in-house measurements. With the requested HFM, more rapid investigations on GHP test conditions can be developed without utilizing NIST GHPs and big scale specimens. Furthermore, specific heat capacity of thermal insulation and PCM materials will be a new thermal measurement property, which is often used as a material parameter for energy storage applications.
