Design Strategies, Technologies and Automation for Achieving Net-Zero Energy Consumption in Civil Buildings

Abstract

The increasing demand for energy-efficient infrastructure and the global urgency to mitigate climate change have accelerated the adoption of Net-Zero Energy Buildings (NZEBs) in the civil building sector. This paper explores the interplay between design strategies, technological and automaton innovations aimed at achieving net-zero energy performance in civil buildings, such as schools, hospitals, government facilities, and community centers. It emphasizes a two-tiered approach: prioritizing passive design strategies like site orientation, thermal mass utilization, natural ventilation, and daylighting, before deploying active technologies like solar photovoltaic systems, high-efficiency HVAC, Building Management Systems (BMS), and energy storage solutions. Key challenges deterring the full realization of NZEBs include high initial costs, lack of technical expertise, inadequate policy frameworks, and inconsistent user behavior. To address these issues, the paper recommends integrated design thinking, capacity development, climate-responsive planning, policy and software engineering support through performance-based building codes and financial incentives. By showcasing global best practices and referencing successful case studies, the paper concludes that achieving net-zero in civil buildings is both feasible and imperative.
