Residential Building Energy Conservation in Mediterranean Climate Zone by Integrating Passive Solar and Energy Efficiency Design Strategies

open access: yesBuildings, 2023
Residential buildings have a list of functions, and one of the top priories is the thermal comfort of its occupants. Thermal comfort can be one of the measurements of successful building performance, and it can be addressed in various ways to provide a ...

Investigating the Influence of Thermal Conductivity and Thermal Storage of Lightweight Concrete Panels on the Energy and Thermal Comfort in Residential Buildings

open access: yesBuildings, 2023
Phase change materials (PCM) are integrated into lightweight concrete (LWC) panels to increase their thermal mass. However, the integration of PCM into LWC also increases the thermal conductivity of the panels, which may have a negative impact.

Thermal quadrupole method with internal heat sources [PDF]

open access: yes, 2012
A new method based on the thermal quadrupoles technique for heat transfer modelling in multilayered slabs with heat sources is proposed. Classical thermal quadrupoles use hyperbolic functions and numerical problems occur according to the argument value ...

Impact of Material Solutions and a Passive Sports Hall’s Use on Thermal Comfort

open access: yesEnergies, 2023
High outdoor temperatures and thermal gains due to solar radiation, which penetrates the interior of buildings as the climate warms up, pose a major challenge to maintaining thermal comfort in passive sports facilities.

Protecting the baryon asymmetry with thermal masses [PDF]

open access: yesPhysics Letters B, 1994
We consider the evolution of baryon number $B$ in the early universe under the influence of rapid sphaleron interactions and show that $B$ will remain nonzero at all times even in the case of $B-L = 0$. This result arises due to thermal Yukawa interactions that cause nonidentical dispersion relations (thermal masses) for different lepton families.

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

open access: yes, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Intrinsic Evaporative Cooling by Hygroscopic Earth Materials

open access: yesGeosciences, 2016
The phase change of water from liquid to vapor is one of the most energy-intensive physical processes in nature, giving it immense potential for cooling. Diverse evaporative cooling strategies have resulted worldwide, including roof ponds and sprinklers,
