**C) Community Spaces** (6C,0I)

**Spatial characteristics:** Shared spaces open to the entire community, without associated studios and with a functionality different than traditional residential spaces.

**Frequency:** 1 Coworking per building 1 Gym per building 

**Functionality:** Gym / coworking / event spaces / playground / terraces 

**Network:** "Differs between spaces, should be tailored to each community space". Active use of network during the day for working and exercising and gathering during the night 

**Access and privacy:** Design access and permits according to each space and COVID-19 (restrictions if applicable). Recommendation to maintain frequently used spaces like coworking without a lock. Shared spaces visited by upt to 79% of the colivers (gym)

**Electricity consumption:** AC has a big impact on electricity consumption in the spaces (6C) 

Community spaces are the core gathering spaces of the Coliving. Monitor occupancy patterns, regulations and capacity of this spaces. Install booking systems or informative boards in those that require strict capacity regulations to ensure comfort and comply with regulations such as COVID-19, like coworking (6C) or gym (0I). In spaces more vulnerable to extreme temperature (6C) automatic windows and AC system to ensure climate comfort, review the design of terraces and building envelop design to reduce temperature variation // Ensure envelope acoustic insulation and impact sound insulation at (6C, above cluster spaces) for social gatherings to avoid interfering with neighbourhood // As these spaces are used by a large volume of colivers at the same time, ensure there is a clear understanding of the use of spaces and their functionality, implement coexistence guides to be designed and respected by the community

## **4. Discussion**

As buildings are made smarter, AEC practitioners must integrate the latest technologies to adapt to a rapidly changing society and respond to sustainable HCD spaces [1]. The seamless Post-Occupancy Framework enabled to create a methodology to monitor and adapt the space to user needs over time. It is important to note that the SPs were not an objective itself, but a dynamic, interactive flashcard that provided inputs from the use of spaces. They are a means of dialogue between users and AEC practitioners to improve space design, iterate, modify physical characteristics of space, and analyze how it affected to colivers routines and the use of spaces through the digital trail of the users.

The SPs are therefore scalable and can be implemented globally, adapting to different buildings, locations and taking into consideration the different restrictions or regulations such as the COVID-19 restrictions in place during the time of study. The SPs are a powerful iterative, spatial tool to interact with residents use of space, and behavioral patterns to improve future design, optimize spaces and assess comfort and wellbeing.

Central Cluster spaces are visited by 14%–43%, an average of 29.7% (21.2 colivers), and the largest electricity consumption and visits are within weekdays at lunch and dinner hours, whereas the Lateral Clusters are visited by only 4%–17% of the community which meant an average of 10.3% (7.4 visitors from other clusters) and has a high consumption of internet at 21:00 h, mostly individual connections inside the private studios. Community Spaces like the gym had a visitor rate of up to 79% and coworking was preferred to be open without restricted access during the day.

Cluster spaces had a higher electricity consumption rate during lunchtime and dinner time mainly due to intensive use of appliances; community spaces like coworking spaces intensified electricity consumption gradually during the afternoon due to AC during the summer months—the rest of the months they encountered a plateau-shaped stable consumption trend. Central Cluster spaces acted as catalyzers of community, colivers visited an average of three to four common spaces, Central Clusters being frequented more by external visitors.

Our consultations with colivers were also essential to complementing and understanding their choices as key to HCD. Interviews and codesign to improve SPs is always recommended as a future line of research. For example, after identifying the electricity patterns and consumption habits of users, the results of the current research recommended modifying the electricity contract to be adjusted to match the peak hours of consumption of the Coliving in order to match their habits. In addition, other measures were suggested to improve wellbeing and use of spaces. Feedback also showed that colivers had a significant interest in the following: understanding building and performance, environmental sustainability, knowing how to improve performance and suggested visualization measures to reduce environmental impact. This interaction helped not only to improve the performance of current spaces but also to collaborate for a more conscious future society.

The use of space routine also differs depending on the day of the week: at weekends, the number of in-house common dinners was significantly reduced and mobility within the Coliving decreased and shifted towards late mornings and night-time rather than during the week when it is distributed more evenly along the day.

Colivers also showed different habits and patterns of use of space: more social colivers visit up to eight spaces apart from their private studios on average, others just one or two. After the study the Central Cluster spaces were recommended to colivers more interested in networking and community interaction and Lateral Clusters to others looking for more independence.

#### *Future Lines of Research*

In future lines of research, the researchers would complement and enhance the research by repeating the process in other buildings with a different typologies and other available data sources to be processed, such as open databases to track interaction with the city and sociodemographic data.

Including surveys to the colivers to enlightening colivers motivations for choosing coliving and their perception of the different spaces would be an additional value-added study for future research.

A post COVID-19 assessment of the building will also be performed to add additional feedback on the building and comparison of data during and post-COVID-19 crisis.
