Special Issue Information

Dear Colleagues,

Buildings are increasingly expected to deliver healthy indoor environments while reducing carbon emissions and supporting renewable-rich energy systems. These goals are physically interconnected. Heat, moisture, airflow, and pollutant transport govern indoor environmental quality and HVAC loads, whereas building envelopes, thermal storage, and control strategies determine how flexibly energy demands can be satisfied. Coupled heat and mass transfer therefore provides a common physical basis for linking indoor health, thermal comfort, energy efficiency, and grid-responsive operation. This Special Issue aims to enhance the understanding of heat-and-mass-transfer mechanisms and translate them into improved building technologies and operational strategies.

We welcome original research and review articles addressing two interconnected themes: (1) healthy indoor environments, including indoor air quality, pollutant and bioaerosol transport, ventilation and air purification, and exposure and health assessment; and (2) energy-flexible buildings, including advanced envelopes and passive cooling, HVAC and thermal energy storage, demand response and renewable-energy integration, and intelligent building control. Studies that explicitly couple indoor environmental processes with flexible building operation are particularly encouraged. Experimental, numerical, field, and system-level investigations of coupled heat and mass transfer are all welcome.

The collection aims to advance healthy, low-carbon, climate-resilient, and energy-flexible buildings.

Hourly angle optimization for photovoltaic (PV) shading is conducted by selecting values from independent fixed-angle simulations, although the selected hours do not share a consistent building thermal history. This study develops a database-based constant-action rolling horizon look-ahead heuristic that minimizes net electricity for a PV louver in a Beijing office while correcting thermal-history inconsistency. Nineteen angles from 0° to 90° were simulated to construct hourly thermal and PV maps. Schedules were generated for horizons of 1–48 h under a 10° h−1 movement limit and evaluated by continuous EnergyPlus replay. The independently optimized sequence predicted −310.90 kWh of annual net energy, whereas continuous replay yielded −101.61 kWh, revealing a 209.29 kWh state-inheritance error dominated by HVAC electricity. The 12 h horizon minimized net energy at −119.11 kWh. A 24 h horizon incurred a 5.89 kWh penalty while reducing angle changes and total rotation by approximately 65%, indicating a favorable energy–movement compromise. Requiring an angle of at least 15° during occupancy eliminated full closure at a net-energy cost of 35.79 kWh. Continuous replay and operating constraints are therefore necessary when translating fixed-angle databases into implementable façade controls. Full article
