• Hybrid GO-MXene nanofluids cut PV thermal resistance by 41.1%. • 3D-OHP with nanofluids boosts PV output by 14.9%. • GO-MXene cools PV panels by 24°C, enhancing efficiency. • Nanofluid cooling adds 43 W/day power, improves exergy to 30.9%. • LCOE analysis confirms cost-effective PV thermal management. The efficiency and longevity of photovoltaic (PV) panels are significantly impaired by excessi…

• Energy sharing and innovative façade designs improve value of solar energy. • 10–12% improvement in solar energy value is obtained via energy sharing in building. • Shading and non-optimal building orientation cause a modest value decrease. • Apartment-level analysis shows rather even distribution of benefits. This study provides novel insights on increasing the profitability of solar photovolt…

This research proposes a lightweight and adaptable control strategy for managing smart residential photovoltaic–battery systems, aiming to reduce loads’ uncertainty from the distribution grid’s perspective. The idea is to minimize deviations from a scheduled power profile at the meter level. The profile can be defined dynamically, thus creating a highly versatile yet simple to define management s…

• Coupling of internal thermal mass with buoyancy ventilation, experimental validation • Wood and concrete thermal mass designs compared, both achieve optimal and equivalent performance • Both test buildings reach the same targets for temperature damping (0.7) and ventilation rate (20 L/s) • Surface area of wood thermal mass increased by × 1.42 to compensate for inferior thermal properties • Temp…

While building HVAC system research has long emphasized energy efficiency, efficiency alone cannot deliver the emission reductions required in the building sector. The sufficiency approach aims to reduce overall energy demand while maintaining thermal comfort, well-being, and equity. This article defines the concept of sufficient HVAC; explores existing and emerging strategies such as adaptive co…

• A methodology for assessing and managing energy flexibility in the commercial building sector. • Disaggregation of the electricity load, based on real-time data integrated with information gathered from interviews with technical staff in the building. • A deterministic optimization model that can simulate scenarios involving increases or reductions in flexible loads. • An artificial neural netw…

• Analysed retrofit needs for 9.7 million EPC D-G homes across England and Wales. • Introduced a method to process high-cardinality EPC variables for better modelling. • Used explainable AI to cluster homes by emission drivers and retrofit priorities. • Identified four building typologies with distinct retrofit needs and strategies. • Revealed five local authority clusters to support targeted ret…
