Thermal probe technology for buildings: the transition from laboratory to field measurements

This article describes an attempt to modify the transient line source probe to be useful in making in-situ measurements in the field. The field of construction, as well as many others would benefit if a new thermal probe could be applied to uncontrolled environments. Three case study buildings have been considered to ascertain the validity and reliability of this new technique in ...

Simultaneous measurements of thermal conductivity and thermal diffusivity of rock-marbles using transient plane source (TPS) technique

Knowing the thermophysical properties of insulating building materials is essential in understanding heat loss. In this study, the thermal conductivity and thermal diffusivity of five marble samples were measured using the transient plane source (TPS) technique and compared to results obtained through the transient hot strip (THS) method. The TPS technique is nearly twenty times the initial resistance of the THS method and does not require small sample sizes or ...

A newly composed paraffin encapsulated prototype roof structure for efficient thermal management in hot climate

This study highlights the ongoing search for sustainable and thermally suitable phase-change materials (PCMs), for hot weather building climates, such as Iraq. This new PCM must have an extraordinary heat and cold retention ability. Building industries are interested in using paraffin’s in their roofing materials, because of their thermo-physical properties, their profitability to save on electricity and HVAC (heating-ventilating air conditioning) systems, their local abundance, as well as their ...

Assessment of hydrothermal performance by thermophysical characterization of a crimped glass wool building insulation

Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The transient technique was employed to thermally characterize glass wool ...

Moisture effect on thermal conductivity of some major elements of a typical Libyan house envelope

The Transient Plane Source was used to measure the thermal conductivity of three commonly used building materials in Libya. Changes in construction practices have resulted in houses being constructed of much thinner materials in comparison to the traditionally thick walls common a few decades ago. Technical data that would make modelling heat flow is these newly constructed buildings is lacking. The indoor environment of these newer buildings often undergoes large ...
