Assessing the environmental impacts of product systems has become critical, with emphasis on reducing carbon dioxide emissions in line with the new climate change regime. Accordingly, environmental regulations have been newly issued or have stronger requirements for inducing more energy-efficient and environmentally-conscious product development. Therefore, product developers in new product development are being forced to consider various and heterogeneous design performance and are encountering more difficulty and chaos when selecting the best product design among design candidates. The relevant studies have contributed to providing tools and techniques for increasing the environmental soundness of the product; however, they do not holistically accommodate the quantification of functional and economic metrics, nor do they incorporate the compliance with recent environmental legislations. The present work proposes an environmentally-conscious design method that integrates functional, economic, and environmental assessments with the compliance of the energy-related products (ErP) legislation. This method provides analytical capabilities including: (1) a functional assessment to derive the durability of the product to be embedded for practical measurement in the following assessments, (2) a compliance check to ensure that energy-related products fulfill the ErP directive enacted by the European Union, (3) an economic assessment to calculate the total cost during the product lifecycle by using the life cycle cost concept, and (4) an environmental assessment to quantify the environmental loads of the product by using a simplified life cycle assessment. The present work also includes a case study to demonstrate the effectiveness of the proposed method; to this end, two different electronic vacuum cleaners are compared. The results of the present work help product developers use life cycle design thinking for determining their design parameters by checking their compliance with the ErP legislation and assessing economic and environmental metrics with a mechanical analysis of the durability of product systems.

评估产品系统对环境的影响已变得至关重要，重点是根据新的气候变化制度减少二氧化碳的排放。因此，已经出台了新的环境法规或对环境法规提出了更严格的要求，以引发更加节能和环保的产品开发。因此，新产品开发中的产品开发人员被迫考虑各种不同的设计性能，并且在设计候选者中选择最佳产品设计时遇到了更多的困难和混乱。相关研究有助于提供工具和技术来提高产品的环境安全性；但是，它们并未全面适应功能和经济指标的量化要求，它们也没有遵守最新的环境法规。本工作提出了一种环保设计方法，该方法将功能，经济和环境评估与能源相关产品（ErP）法规的遵从性相结合。该方法提供了分析功能，包括：（1）功能评估，以得出要在以下评估中进行实际测量的嵌入式产品的耐久性；（2）符合性检查，以确保与能源有关的产品符合由EMP制定的ErP指令。欧盟（3）进行经济评估，以使用生命周期成本概念来计算产品生命周期中的总成本；（4）进行环境评估，以使用简化的生命周期评估来量化产品的环境负荷。目前的工作还包括一个案例研究，以证明该方法的有效性。为此，比较了两种不同的电子吸尘器。当前工作的结果可帮助产品开发人员使用生命周期设计思想来确定其设计参数，方法是检查产品是否符合ErP法规，并通过对产品系统的耐久性进行机械分析来评估经济和环境指标。
