Clocks – Classroom Occupancy System

Universities and other Higher Education institutions all share a common complexity – scheduling thousands of classes in the buildings across campus. Each semester, timetabling teams have to go above and beyond to schedule all classes in the available capacity of the campus. However, many classes do not actually take place because of cancellations or other reasons. Additionally, it often occurs that classes are scheduled in classrooms that have a much larger capacity than is actually required. These no-shows and underutilised classrooms cause tremendous inefficiency at great cost, but it’s virtually impossible for timetabling teams to gain these insights and take appropriate actions. Clocks (Classroom Occupancy System) now provides timetabling teams with the data to plan classes more efficiently and improve classroom capacity.


Space is an expensive resource. We’re a inner-city campus with growing space demands so we have to use what we have as efficiently as possible. Clocks will make a huge impact on what we schedule where and when, enabling us to optimise space utilisation

Reduce no-shows and optimise underutilized classes.

Clocks integrates with most accepted timetabling tools in the Educational market and has an official partnership with Scientia, with their market leading timetabling software suite Syllabus Plus. By connecting the timetabling software to the occupancy data of PIE, you can instantly determine how often specific classes did actually not occur (no-shows). Additionally, you can immediately see which classes are structurally underutilised and can be scheduled in smaller classrooms going forward. This also applies to overutilized classes, which need a larger classroom in the upcoming semester. The result is that the timetabling team can plan much more efficiently and more classes can be taught without having to increase the capacity. Expansion investment can, therefore, be postponed or cancelled and more students can be admitted to the campus. By selecting no-shows, timetabling teams can determine which planned classed did not occur and how often that happened. This provides the timetabling team with the right data to improve future schedules.

Filter and semester overview

The search and filter capabilities make it ease to compare different classes. The different columns represent the amount of lost capacity in terms of empty seats or empty hours.

“At the push of a button, my team gains insight into lectures that are consistently under-utilised and how many ‘no-shows’ have taken place in a term or for specific lectures”

— Fred Jonker, Information Services Policy Officer, Wageningen University

Curious about Clocks?

Detailed reports per class

By selecting a class, you will be provided with detailed data on that class, which can easily be grouped on week, type, location, day and time.

Occupancy data on the minute

The occupancy is visualised on the minute accurate by simply hovering the mouse over the occupancy column. Reports can also be shared with coordinators in a split second.

Advanced Settings

On request of many Universities: Compute your own no-shows metrics by moving the slider bars and decide whether you want to have an conservative or more ‘looser’ approach to calculating no-shows.

Make your building intelligent with these apps

PIE is a platform, which makes it easy to develop apps on top of PIE. The data and intelligence inside PIE can simply be approached through the API. Some of these apps are being developed by Lone Rooftop, such as the Building Intelligence Dashboard and Wally, but Lone Rooftop also partners with carefully selected app developers that develop apps on top of PIE. This ensures that PIE can be leveraged throughout the organisation and you can benefit from an ever-growing numbers of apps.
