Air-source heat pump integration to support district heating decarbonization in Lithuanian climate
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Many district heating (DH) systems in Eastern Europe continue to rely heavily on fossil fuels and ageing biomass boilers, limiting operational efficiency and slowing progress toward climate targets. As these systems face ... -
Supermarket refrigeration systems in cold-climate regions: a comprehensive review of waste heat recovery potential, compatibility with district heating network integration, and forward-looking free-cooling-enabled operation
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Supermarkets are among the most refrigeration-intensive commercial buildings, converting a large share of electricity consumption into rejected heat at condensers or gas coolers. In cold climates, low ambient temperatur ... -
Thermal performance and heat flux dynamics of electrically heated windows: a foundation for energy-efficient active glazing systems
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)The building sector remains a primary contributor to global energy consumption, with windows often identified as the least efficient component of the building envelope. This study investigates the thermal performance of ... -
Spatial quantification and economic valuation of recreational ecosystem services in Iran’s Zagros Mountains: a sub-watershed analysis using the Recreation Opportunity Spectrum (ROS) framework
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Recreational Ecosystem Services (RES) deliver critical non-material benefits, yet their spatially explicit valuation remains underexplored in the data-limited, mountainous landscapes of the Middle East. This study ... -
Azimuthal visualization of Artificial Light at Night (ALAN) based on 3D Gaussian Splatting
