Buildings in Canada are responsible for about 35% of all energy use and greenhouse gas emissions about 53% of electricity use. Thus, buildings represent a major opportunity to reduce Canada's environmental impact and need for costly infrastructure. Furthermore, energy costs are very significant to businesses. A promising approach to reducing building energy use and hedging against energy price increases is to implement energy conservation strategies. But, as building equipment, envelopes, and lighting become more efficient, technologies and systems that leverage occupants and data about occupants have become increasingly important. However, this opportunity is only beginning to be recognized and strategies and technologies with long-term proven persistence are lacking. Bentall Kennedy, an award-winning and industry-leading Canadian building operator and manager, has taken many steps to significantly reduce the environmental impact (e.g., energy, water, solid waste, greenhouse gas emissions, transportation, green cleaning) of its buildings. But over 50% of energy is used by lighting and tenant equipment, over which Bentall Kennedy has limited control and influence. In response to these challenges, Bentall Kennedy has upgraded its entire flagship building in Ottawa, World Exchange Plaza, to be submetered. That means, for the first time, that they will have the capability to charge tenants for the electricity they use rather than a floor-weighted proportionate share for the building. The proposed research project is to develop a comprehensive program to reduce energy use by way of technology and occupant and tenant engagement. The multi-faceted approach shall employ a combination of building engineering principles and human factors engineering. Key strategies and deliverables include: 1) a methodology for estimating energy end uses for each tenant; 2) a statistical analysis of energy savings before and after submetered billing; and, 3) effective customized energy use data reporting to tenants. The targeted outcome is energy savings of 10-20% in World Exchange Plaza, which can be extended to Bentall Kennedy's other buildings and much of the rest of the market.

加拿大的建筑物占所有能源使用量的35%，温室气体排放量占电力使用量的53%。因此，建筑物是减少加拿大环境影响和对昂贵基础设施需求的一个重要机会。此外，能源成本对企业来说非常重要。减少建筑物能源使用和对冲能源价格上涨的一个有希望的方法是实施节能战略。但是，随着建筑设备、围护结构和照明变得更加高效，利用居住者和居住者数据的技术和系统变得越来越重要。然而，这一机会才刚刚开始被认识到，缺乏经过长期验证的持久性战略和技术。Bentall Kennedy是一家屡获殊荣的行业领先的加拿大建筑运营商和经理，他采取了许多措施来显著减少对环境的影响（例如， 能源、水、固体废物、温室气体排放、运输、绿色清洁）。但是，超过50%的能源用于照明和租户设备，本托尔肯尼迪对这些设备的控制和影响有限。为了应对这些挑战，Bentall Kennedy将其位于渥太华的整个旗舰建筑World Exchange Plaza进行了升级，以实现分表计量。这意味着，他们将首次有能力向租户收取他们使用的电力，而不是按楼层加权比例分配建筑物。拟议的研究项目是制定一项综合计划，通过技术和居住者和租户的参与来减少能源使用。多方面的方法应采用建筑工程原理和人为因素工程相结合。主要战略和交付成果包括：1）a 用于估计每个租户的能源最终用途的方法; 2）在分项计费之前和之后的能源节约的统计分析;以及3）向租户报告有效的定制能源使用数据。目标是在世界交易广场节省10-20%的能源，这可以扩展到Bentall Kennedy的其他建筑和市场的其他大部分。
