Strategic Synergy of Architecture, Engineering, and Facility Management (AEFM) for Achieving NZEB Under EEP2022 Link to SDGs Scheme

Objective: The objective of this study is to a) derive the National Energy Plan 2022 in synergy with Architecture, Engineering, and Facility Management (AEFM). b) The synergy of AEFM toward SDGs in relation. Theoretical Framework: This quantitative research, including mixed methods, is conducted by gathering literature, including directives from the EEP (2022) and its stakeholders in 3 factors, and synchronizing the relation in mapping with each of the economic sectors. Method: The analysis encompassed a comparative assessment of building envelope, in-room electrical and mechanical loads, and construction materials. The findings formed the basis for an annual energy-saving estimation toward supporting strategic pathways toward achieving NZEB aiming in the healthcare sector. Results: An internal estimation of energy consumption can identify three primary contributors to electricity use: air conditioning units presented 66.50%, lighting accounted for 12.70%, and electrical appliances consumed 20.80%. Cooling management is significant in terms of by load-sharing, bed occupancy and usable floor area, and renewable energy utilization and performance, which can compensate for approx. 7-8% of electrical expenses. Discussion: The strategic integration of AEFM in the pursuit of NZEB. To achieve its performance requires a synergistic approach across these disciplines. First, architectural integration focuses on passive design strategies and energy-efficient building envelopes that reduce thermal loads, and then engineering utilizes energy management data, such as cooling load profile analysis, to cut costs. The FM can manage through investment planning and operational efficiency with cost reduction, e.g., installation of energy-saving window films can save THB 400,000.00 per year, achieving ROI within 2–3 years. The coordinated application of these strategies demonstrates the importance of AEFM synergy in driving the transition to sustainable, high-performance built environments.
