Ms Salma Ragab (Mechanical Power Engineering Dept. Faculty of Engineering – Ain Shams University Cairo, Egypt)Paper Contribution
Building energy consumption has increased significantly due to rising global temperatures, making passive thermal comfort strategies one of the most promising approaches for reducing building energy consumption. In this study, the increase in energy consumption is mitigated using organic Phase Change Materials (PCMs) in roof construction, which enables maintaining thermal comfort with reduced...

Dr Fredrik Skaug Fadnes (University of Stavanger / Norconsult Norge AS)Paper Contribution
The new energy plant at the University of Stavanger is an advanced campus energy hub for high-efficiency heating and cooling, using ammonia heat pumps connected to geothermal boreholes and dry coolers within an integrated low-temperature energy infrastructure. Although such systems are designed to improve energy efficiency and operational flexibility, there is often a gap between design intent...

Dr Tesfaye Hurrisa (Adama science and Technology university)Paper Contribution
Managing energy consumption and thermal radiation is crucial for environmental sustainability. Passive radiative cooling (PRC) has recently emerged as an effective method for reducing environmental energy density without external power input. This study investigated three wavelength ranges (2.5–5 μm, 8–13 μm, and 16–27 μm) to optimize cooling performance. Optical and electrical properties were...

Prof. Ove Tobias Gudmestad (University of Stavanger)Paper Contribution
Burning LNG to obtain heat and electric energy reduces greenhouse gas emissions considerably compared to burning coal in coal-fired plants. LNG is by many considered to be an ideal source of energy for the transition to zero greenhouse gas emissions.

In the process of evaluating the sustainability of using LNG, all the emissions to the air must be considered. This also applies to the... -
Mr Mohamed Hashem Abdelrahman (UIS)Paper Contribution
Farming is becoming increasingly energy-demanding due to the widespread adoption of Agriculture 4.0 technologies and decarbonization policies. To address this challenge, the transition toward sustainable energy and widespread deployment of on-farm renewable energy systems (RES) is needed.

Dr Asmaa El-Sayed (Asmaa R. El-Sayed), Ali Kattaia (Ali Kattaia)Paper Contribution
Energy is the major key to every evidence of modern civilization. Increasing challenges to sustain reliable and durable energy supplies are enforcing us to optimize our usage of these resources. HVAC applications are one of the relatively main fields consuming energy resources. The increasing demand to optimize these systems by researchers needs to simulate this system to easily modify,...

Dr Tesfaye Hurrisa (Adama science and Technology university)Paper Contribution
Nonrenewable fossil fuels are the primary source of energy used globally. In this study, we have designed a broadband, wide-angle, and polarization-independent grating metamaterial (MDM) emitter for thermophotovoltaics (TPV), which falls under the category of renewable energy. The electronic and optical properties of materials, model metamaterial structures, and simulate their optical...

Thaer Syam (Texas A&M University)Paper Contribution
This study develops supervised machine-learning surrogate models for the molar volume of compositions within the Ni–Co–Cr ternary system, trained on CALPHAD-generated data. Molar volume is a fundamental thermodynamic quantity related to density and to temperature-dependent volumetric expansion, and is therefore relevant to the design of compositionally graded alloys. The original dataset...

Ali Karimi (Department of Energy and Petroleum Engineering, University of Stavanger, Stavanger, Norway)Paper Contribution
Residential space heating and domestic hot water are key targets for decarbonization in cold climates. This paper presents a high-fidelity digital twin of a solar-assisted heat pump system for a multi-zone residential building. The system integrates an R32 heat pump, 10 kWp photovoltaic array, 10 kWh battery energy storage system, 262L thermal buffer tank, and 204L DHW tank. To improve...
