New simulation tools for daylight have been tested on specific building types, mostly offices and schools. To date there have been very few simulation-based studies of daylighting in multi-unit residential buildings. Recent studies have shown strong connections between daylight and occupant wellbeing, not only in places where people work and study,...

... The study examines MURB floorplans that are single aspect, size lit, one bedroom units with a floor to ceiling height of 8' (2.4m). While our earlier research found that window to wall ratios above 70% did not positively impact daylight [1] in this study we did not vary the WWR, we used 100% WWR to simplify our massing model and maximize the amount of light that could possibly enter floorplans. This study assumed the units are occupied 8am-6pm with Daylight Savings Time (DSTI) invoked, analyzed in 60 minute increments. ...
Condominiums have become the predominant housing form in Canada, and connection to the outdoors, adequate fresh air, and appropriate levels of daylight are essential to people's quality of life. The majority of new condos have balconies, but there are no climate-specific balcony guidelines for comparing design options for multi-unit residential buildings
(MURBs) with balconies. To date, studies of MURBs have focused on other important parameters including energy efficiency, indoor comfort, daylight, and resilience, but there is a significant research gap relating to balcony design. Balcony spaces are often underutilized, and shade both the living spaces inside and the units below. This research presents a research framework and preliminary results of a simulation-based study to quantify the impacts of three typical balcony designs on daylight in MURB dwellings. The framework and findings presented form part of a larger and more comprehensive simulation-based study that will provide the basis of design guidelines for balconies.
Access to acceptable levels of daylight are important for people’s quality of life. Multi-unit residential buildings (MURBs) are known to perform poorly in terms of daylight compared to other residential building types. There are neither appropriate agreed upon metrics, nor effective methods for designing for daylight in MURBs. This paper presents results of a speculative design study that utilizes generative design to explore alternative geometries for the MURB tower typology. The experiment combines a genetic algorithm for spatial variation with climate-based daylight modeling (CBDM) to test the new forms against variations of the point tower MURB floorplan are commonly used. This paper identifies the poor performance of typical MURBs for daylight, and proposed new techniques for form generation. A new workflow has been developed and tested and a number of challenging issues have been identified.
