Abstract
This study outlines MEP planning and HVAC design for a zero-energy research facility. The building integrates renewable systems: a groundwater heat exchanger, biomass CHP using gasified wood, 200 kW of photovoltaics, and 4,600 kWh battery storage for potential off-grid operation. Passive architectural strategies reduce thermal loads, while the ABW-based interior offers flexible environments. The HVAC system uses occupant-centric control, adjusting outdoor air volume by real-time occupancy and maintaining surface temperature uniformity via radiant panels. Three types of low-power personal air conditioning devices, smartphone-controlled and integrated into ceilings and desks, provide personalized comfort. This holistic approach supports energy neutrality and enhances occupant well-being..
