Canada is a leader in the construction of tall buildings in North America. In the Toronto area, the type of tall buildings constructed has changed dramatically in the past 15 years. Before 2000, 90% of tall buildings were offices; today, 90% are residential. This change has challenged the construction industry as residential high-rises are much more complex than office structures of similar height. For example, while office buildings require minimal interior finishes to allow for maximum flexibility for potential tenants, residential units must be completely finished. Further, office spaces are served by central heating, cooling, and ventilation (HVAC) systems whereas residential units often have individual HVAC systems and have operable doors and windows to connect residents to the outside. These differences significantly affect the energy consumption and construction requirements of the units. This research aims to address the many issues being experienced by high-rise residential builders. Three main topics will be examined: productivity during construction, construction impacts on stack effect, and, a life cycle evaluation of modular cladding systems. These three topics were identified as pressing needs by the industry.

加拿大是北美高层建筑建设的领先者。在多伦多地区，过去15年里，高层建筑的类型发生了巨大的变化。 2000年之前，90%的高层建筑是办公楼；如今，90% 都是住宅。这一变化给建筑行业带来了挑战，因为高层住宅比类似高度的办公建筑复杂得多。例如，虽然办公楼需要最少的内部装修，以便为潜在租户提供最大的灵活性，但住宅单元必须完全装修。此外，办公空间由中央供暖、制冷和通风 (HVAC) 系统提供服务，而住宅单元通常拥有独立的 HVAC 系统，并具有可操作的门窗以将居民与外界连接起来。这些差异极大地影响了机组的能耗和建设要求。 这项研究旨在解决高层住宅建筑商遇到的许多问题。将研究三个主要主题：施工期间的生产率、施工对烟囱效应的影响以及模块化覆层系统的生命周期评估。这三个主题被业界确定为迫切需求。
