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.

加拿大在北美的高层建筑建设方面处于领先地位。在多伦多地区，高层建筑的类型在过去15年里发生了巨大的变化。2000年以前，90%的高层建筑是办公楼；如今，90%是住宅。这种变化给建筑行业带来了挑战，因为住宅高层建筑比同等高度的办公建筑复杂得多。例如，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，而住宅单元必须完全完工。此外，办公空间由中央供暖、制冷和通风（HVAC）系统提供服务，而住宅单元通常有单独的HVAC系统，并有可操作的门窗将居民与外部连接起来。这些差异显著影响了机组的能耗和建设要求。
