Mandal et al. propose and demonstrate that selective longwave infrared-emissive exterior envelopes can keep walls and windows of buildings cooler than traditional exterior envelopes in hot weather and warmer in cold weather. Achievable by simple means, this passive radiative thermoregulation can enable untapped energy savings in buildings.

Graser et al. present the evolution, governance, and impact of QGIS, a leading geographic information system (GIS). They highlight its role in democratizing geospatial data management and analysis, enabling open and reproducible research, and fostering digital sovereignty through sustainable open-source development. By examining its governance and development model, this paper underscores how QGIS provides a robust, accessible alternative to proprietary GIS solutions, ensuring that spatial analysis remains transparent, inclusive, and globally impactful.
