“…The literature suggests that PU insulations perform 39.1%-59.3% better compared to conventional insulation materials based on mean thermal conductivity. The data is supported by an analysis of 23,700 numerical measurements of conductivity for various insulation types, where PU insulation is shown to outperform all other common insulation materials (Domínguez-Muñoz et al, 2010;Márquez et al, 2017). For new buildings aiming at achieving zero carbon emissions and existing buildings aiming to alleviate fuel poverty, polyurethane offers higher potential for energy savings and thermal comfort (Kumar and Suman, 2013) compared to conventional materials.…”

We systematically review the impact of polyurethane insulation and polyurethane household products on the indoor environmental quality of buildings. The review breaks down polyurethane products into constituent compounds (isocyanate, polyol, flame retardant, blowing agent and catalyst) as well as secondary emissions, and discusses their implications on human health. Concentrations of compounds emitted from insulation, and household materials, measured in laboratory experiments and case studies are presented in the context of the built environment.We would like to thank Dr Dustin Poppendieck (National Institute of Standards and Technology) and Elizabeth Cooper (UCL Institute for Environmental Design and Engineering) for critically reviewing the paper and assisting with expert advice on exposure assessments and organic emissions. Their suggestions and valuable comments improved and clarified the manuscript.The lead author is part of the Centre for Doctoral Training in Science and Engineering in Arts, Heritage and Archaeology (SEAHA).

“…Configuration (a) and (d) do not require the use of a cooling tower. System configurations that produce hot water at 40 to 50 • C are suitable for terminal units, such as fan-coils or a combination of radiant floor and fan-coils [35]. However, the configuration DA + DL/H&C (configuration (f)) produces hot water at 60 • C, so this temperature might be suitable for heat radiators.…”

Recovery and Transport of Industrial Waste Heat for Their Use in Urban District Heating and Cooling Networks Using Absorption Systems

The use of industrial excess heat in district heating networks is very attractive. The main issue is the transport of the heat from the point of generation to the local distribution network, in a way similar to the structure of electricity transport and distribution networks. Absorption systems have been proposed to transport and distribute waste heat using two absorption stations. In one of them (step-up station), industrial heat at a low temperature is pumped to a higher temperature to facilitate its transport and at the same time increase the temperature difference between the supply and return streams, in this way reducing the hot water mass flow rate circulating through the heat transport network. Heat is then used in a second absorption system (step-down station) to provide heat to a low temperature local district network. In this paper, several absorption system configurations are analyzed for both stations. A detailed thermodynamic analysis of each configuration is performed using selected energy performance indicators to calculate its global performance. The implementation of these kind of systems could enable the use of waste heat to produce heating and cooling for smart communities located a few dozens of kilometers away from industrial sites.

“…Not only do such systems clearly improve user comfort, they also avoid moisture from condensing on cold surfaces. The challenge then becomes that of reducing energy consumption and limiting the costs of installation [17]. Sun et al explored the possibility of coupling outdoor air cooling with underfloor cooling under a warm and humid climate, such as that of Korea; they achieved cooling energy savings of over 20% compared to usual cooling systems [18].…”

The present study focuses on the application of large-format thermal ceramic conditioning panels (TCPs) containing polypropylene (PPR) capillary tube mats in dwellings on the Mediterranean coast. The thermal and energy behaviours were examined once the underfloor heating was installed, and they were compared with an alternative wall application. The system was implemented in a single-family house located on the Spanish Mediterranean coast. After having monitored the house during a complete one-year cycle, the annual energy demand was quantified using the Design Builder tool. TCP panels applied to radiant floors reduced energy demand by 5.15% compared to the wall-layout alternative. Significant reductions in CO2 emissions were also achieved, as well as a 25.19% reduction in energy demand compared to convection systems. The incorporation of 24 m2 of solar thermal panels into the system, combined with solar cooling systems based on lithium chloride, was also analysed. A reduction in energy demand of 57.46% was obtained compared to all-air convection systems. Finally, the amortisation periods of the investments in TCP panels and solar panels were calculated and compared to a convection system. Underfloor TCP panels proved to be more cost-effective than a wall installation. The additional cost of EUR 21,844 could be amortised over approximately 14 years with the radiant underfloor TCP system, while the wall TCP would be amortised over 17.4 years.
