The vision of this research program is to evaluate, identify and fill many of the gaps that exist in the development of an integrated platform, which is used to assess and analyze the design of sustainable elderly-friendly buildings (SEFBs) for Canadians at the initial stage within the concept of Building Information Modeling (BIM). The notion of elderly friendly buildings is relevant to the construction industry because it takes into consideration a variety of factors related to human needs. This is of high importance given the increased aging population in Canada, which is expected to account for 25% of Canada’s population by 2051. The aim of sustainable design is to create homes that are livable, comfortable and energy efficient. Sustainable design requires reducing depletion of critical resources and preventing environmental degradation caused by facilities throughout their life cycle. The challenge facing the Architect/Engineering/Construction (A/E/C) industry in relation to sustainability is to meet the demands of new and renovated facilities that are secure and healthy while minimizing their impact on the environment, society and economy. To improve energy performance, we use materials with minimal life-cycle environmental impacts (EIs), which are part of the fundamental principles for sustainable design. BIM technology enables engineers to design and create virtual models while visualizing and evaluating various design alternatives before construction begins. Designers use BIM tools to create 3D models wherein associated components are selected from a built-in database. However, information related to sustainable design is not yet incorporated into these models. Predicting energy consumption and expenditures of SEFBs at the initial design stage will contribute to reducing energy and resource costs. Yet, it is beneficial to apply an initial method at the feasibility stage to identify the components needed to design and construct SEFBs, to assess their EIs, and to analyze their costs within BIM environment. Critical decisions about the continuation or dismissal of projects are made during the initial design stage, in which the available information is limited. However, these decisions are based on feasibility studies that evaluate the cost, benefit and profitability of projects without entailing detailed data and design expertise or experience. Decision makers are in need of dependable techniques and tools that they can use when deciding on the status of building projects. Therefore, it is vital to establish an initial design strategy to better understand the components needed to do SEFBs, and to evaluate and classify their related costs and benefits. To apply such a strategy, it is essential to develop a fully integrated platform that integrates BIM and sustainability requirements at the initial design stage of building construction.

这项研究计划的愿景是评估、识别和填补综合平台开发中存在的许多空白，该平台用于在建筑信息建模(BIM)概念的初始阶段评估和分析针对加拿大人的可持续老年人友好型建筑(SEFBs)的设计。 老年友好型建筑的概念与建筑业相关，因为它考虑了与人类需求有关的各种因素。考虑到加拿大老龄化人口的增加，这一点非常重要，预计到2051年，加拿大老龄化人口将占加拿大人口的25%。可持续设计的目标是创造宜居、舒适和节能的家园。可持续设计要求减少关键资源的消耗，防止设施在整个生命周期内造成环境退化。建筑师/工程/建筑(A/E/C)行业在可持续性方面面临的挑战是满足安全和健康的新设施和翻新设施的需求，同时将其对环境、社会和经济的影响降至最低。为了提高能源性能，我们使用生命周期环境影响(EIS)最小的材料，这是可持续设计的基本原则的一部分。 BIM技术使工程师能够设计和创建虚拟模型，同时在施工开始之前可视化和评估各种设计备选方案。设计人员使用BIM工具创建3D模型，其中关联的组件是从内置数据库中选择的。然而，与可持续设计相关的信息尚未纳入这些模型。在初始设计阶段预测SEFBs的能源消耗和支出将有助于降低能源和资源成本。然而，在可行性阶段应用初始方法来确定设计和建造SEFBs所需的组件、评估其EIS并在BIM环境中分析其成本是有益的。 关于继续或取消项目的关键决定是在最初的设计阶段做出的，在这个阶段，可用的信息有限。然而，这些决定是基于可行性研究，评估项目的成本、效益和盈利能力，而不需要详细的数据和设计专业知识或经验。 决策者需要可靠的技术和工具，以供他们在决定建设项目的状态时使用。因此，建立初始设计战略，以便更好地了解进行SEFBs所需的组件，并对其相关成本和收益进行评估和分类，是至关重要的。要应用这种战略，必须开发一个完全集成的平台，在建筑施工的初始设计阶段整合BIM和可持续发展要求。
