Abstract

This study presents a multi-objective optimization methodology for building renovation, integrating a holistic and prospective approach. The methodology incorporates thermal discomfort into the Life Cycle Sustainability Assessment, addressing a critical gap in existing approaches that undermine the effects of climate change.
The methodology involves using Building Dynamic Energy Simulation to quantify energy consumption and thermal discomfort, Life Cycle Assessment for environmental impacts, and Life Cycle Cost analysis for economic evaluation. The study integrates Pareto-optimal strategies and multi-criteria clustering to identify archetypes of optimal renovation strategies which represent a trade-off between environmental (carbon footprint), economic (direct global cost) and comfort (thermal discomfort) objectives.
A case study on a French residential building explores over 11,000 renovation strategies under varying climate zones and initial energy systems. In all configurations, carbon footprint and direct global cost values for optimal renovation strategies are not widely dispersed around median values, with relative dispersions inferior to 0.32. However, thermal discomfort following optimal renovations is strongly dependent on climate zone, with a relative dispersion of 1.15 in the context of a warm French climate (H3). 4 to 5 clusters of optimal renovation strategies have been identified for every configuration, highlighting the possible trade-offs between the 3 objectives. Gas-based systems are consistently replaced by thermodynamic solutions, whereas the type and performance of envelope insulation differ across clusters. In all configurations, the majority of optimal renovation strategies include solar protections (56–62%), while cooling systems are implemented less frequently, appearing in only 20–38% of cases.
将生命周期可持续性评估纳入建筑改造策略
本研究提出了一种多目标的建筑改造优化方法,整合了整体性和前瞻性的方法。该方法将热不适纳入生命周期可持续性评估,解决了现有方法中破坏气候变化影响的关键空白。方法包括使用建筑动态能源模拟来量化能源消耗和热不适,使用生命周期评估来评估环境影响,使用生命周期成本分析来进行经济评估。该研究整合了帕累托最优策略和多标准聚类,以确定最优装修策略的原型,这些策略代表了环境(碳足迹)、经济(直接全球成本)和舒适(热不适)目标之间的权衡。对法国住宅建筑的案例研究探讨了在不同气候带和初始能源系统下的11,000多种改造策略。在所有配置中,最优改造策略的碳足迹和直接全局成本值在中位数附近并不广泛分散,相对分散度小于0.32。然而,最佳改造后的热不适强烈依赖于气候带,在温暖的法国气候背景下,相对分散度为1.15 (H3)。针对每种配置确定了4到5组最优改造策略,突出了3个目标之间可能的权衡。基于气体的系统一直被热力学解决方案所取代,而不同簇的包络层隔热的类型和性能不同。在所有配置中,大多数最佳改造策略包括太阳能保护(56% - 62%),而冷却系统的实施频率较低,仅占20-38%。
