Abstract Nearly zero-energy buildings have become a global trend in building energy conservation. While China has achieved success implementing such severely cold regions, improvements are still needed hot summer and winter regions. This study analyzes the climate characteristics heat transfer properties of China’s proposing both active passive energy-saving strategies suitable for this climate. Using residential Hangzhou, Zhejiang Province as case study, we conducted comparative analysis between conventional nearly using GBVEL software. Through detailed simulation modeling, established comprehensive system structures including envelope configurations, material properties, thermal performance characteristics. The results demonstrate that optimized can reduce coefficients by up to 47% compared buildings. Various measures were evaluated through parametric analysis, revealing integrated approaches combining enhanced insulation, window systems, renewable integration achieve reductions 89.5%. shows 100 m² rooftop photovoltaic combined with ground-source pumps offset 25.8% cooling 44.7% heating demands. provides practical guidance regions assessment layout, green areas, optimization, efficiency improvements.

Indonesia's urbanization issue ranks fourth in Southeast Asia. Urbanization correlates with a 1% increase emissions for every the population. In building sector, this trend will demand construction, impacting resources such as power plants (energy sector). The energy sector contributes highest carbon at 94.64%. This rise can hinder goal of reducing by 29% 2030. Nearly Zero Emission Building (NZEB) approach is proposed solution efficiency. NZEB involves steps during pre-construction phase using passive strategies and post-construction active through operations to reduce needs. research uses qualitative method based on three standards from countries different climates review implementation results. analysis results show strategies: (orientation, natural lighting, ventilation), (Building Management Systems (BMS), renewable use, materials), alignment Green maximize approach. Indonesia, Council Indonesia (GBCI) necessary. GBCI has designed Greenship "Net Zero," focusing assessments air quality, openings, emission reduction calculations. help quantitatively sector.

In the current context of huge global energy consumption and harsh climatic conditions, efficiency sustainability buildings have received much attention. The nearly zero-energy building (nZEB) is a feasible solution for solving crisis in sector recent years, it important to study adaptability its technology system. However, existing studies not addressed well issue impact complex diverse climates on systems nZEBs. Secondly, contrast residential buildings, office need be further developed. This takes hot summer cold winter (HSCW) zone China as an example uses numerical simulations orthogonal experiments investigate under climate conditions. results show following: (1) Passive technologies are greatly affected by complexity diversity climates. Optimal envelope thermal parameters tailored specific zones identified. Specifically, optimal level KWALL CT HSCWC 0.2 W/(m2·K), HSWWT 0.3 W/(m2·K); KROOF 0.15 0.25 (2) Active do mainly receive influence climates, ED, HR, TS measures should adopted buildings; (3) rational utilization renewable influenced local resource evaluates GSHP, ASHP, BIPV technologies. To better meet requirements recommended adopt GSHP ASHP HCWWT zone. will helpful development other zones.
