Special Issue Information

Dear Colleagues,

Low-energy buildings and low-carbon grid systems are important for achieving carbon neutrality in the building sector, as the largest contributor to global final energy use and carbon emissions. The synergy between low-energy buildings and low-carbon grid systems is a key pathway toward sustainable energy transition. Low-energy buildings reduce operational energy consumption and carbon emissions through optimized envelope design, enhanced efficiency, and the integration of renewable energy. Meanwhile, low-carbon grid systems incorporate renewable generation, energy storage, and intelligent control technologies to maintain energy balance and grid stability. The integration of these two systems enables demand-side management, load optimization, and improved resilience in achieving carbon reduction targets. However, several technical challenges remain, including storage degradation, energy congestion between renewable sources and the grid, and flexible grid operations.

Low-energy buildings and low-carbon grid systems are forms of sustainable energy development. Advanced design strategies in low-energy buildings contribute to significant reductions in operational demand, and their integration with low-carbon grids facilitates the utilization of renewable resources, load optimization, and system stability. Moreover, the transition from isolated building energy saving to integrated building grid synergy provides effective pathways for energy planning, intelligent management, and interactive energy sharing, thereby accelerating the establishment of a carbon-neutral urban energy community.

Considering the growing interest in this topic, we are organizing a Special Issue entitled “Low-Energy Buildings and Low-Carbon Grid Systems”, aimed at reporting the most recent findings by researchers and sector professionals. Original manuscripts are encouraged, covering the following themes:

  • Low-energy buildings;
  • Low-carbon grid systems;
  • Demand response;
  • Grid and building energy system integration;
  • Smart energy system;
  • Grid-responsive buildings.

We look forward to receiving your contributions.

Abstract

Heating, ventilation, and air conditioning (HVAC) systems struggle to maintain optimal thermal comfort because perception is subjective and varies significantly across individuals. Traditional uniform cooling strategies often overlook demographic diversity, leading to inequitable comfort outcomes and inefficient building operations. To address this limitation, this study analyzed a web-based survey of 366 university occupants using a partial proportional odds model with multiple imputation and inverse-frequency weighting. Interaction terms, specifically Age–Activity, Gender–Clothing, and Age–Clothing, were included to assess combined effects that reflect demographic disparities in adaptive capacity. The results show that clothing insulation, activity, age, gender, race/ethnicity, and space type significantly influence thermal responses. Notably, male occupants were more than three times as likely to report feeling too warm (odds ratio [OR] = 3.24), whereas older adults exhibited significantly lower odds of reporting feeling too warm (OR = 0.42). Substantial variation was observed across racial and ethnic groups (ORs ranging from 2.4 to 6.5). These findings highlight the limitations of traditional population-average comfort approaches and provide valuable scientific insights for demand-response-ready HVAC strategies that adjust temperature setpoints dynamically without sacrificing comfort. By offering accurate, real-time estimates across diverse thermal ranges, these occupant-centric models reduce HVAC energy use and associated emissions at the building scale while supporting ancillary services for flexible load shifting and smarter coordination within low-carbon electric grids. Ultimately, incorporating demographic and contextual diversity into building controls reduces unnecessary cooling waste while promoting thermal equity, establishing a human-centric foundation for sustainable built environments.
