| Abstract |
The concept and technology of zero energy building/house (ZEB/H) has been developed as an effective solution to reduce greenhouse gas (GHG) emissions and energy consumption in buildings. This paper analyzes ZEB/H research done for the past decade to provide insights and accelerate its implementation in the active system sector. It investigates key research areas in heating, ventilation, air conditioning and refrigeration (HVAC&R) systems, identifies enabling technologies and proposes a technical direction and roadmap for achieving ZEB/H. The study focuses on energy-efficient heating/cooling, ventilation, renewable energy, and design strategy of HVAC&R systems. The analysis also highlights the significance of domestic hot water (DHW) systems in ZEB/H implementation, covering topics such as DHW profiles, demand forecasting, control, and system design. It emphasizes that residential and nonresidential buildings require different research approaches, with nonresidential focusing on HVAC&R and residential emphasizing domestic hot water and ventilation. The future development of ZEB/H active systems should incorporate digital technology in HVAC&R, integrate renewable energy and optimal operation technology, establish regional heat networks and integrate building and active systems. |
