Building Intelligence

PIE: Realtime occupancy platform for the next generation of data-driven Facility & Real Estate managers

The Position Intelligence Engine (PIE) is a cloud-based technology platform that makes buildings intelligent by using real-time data. Based on smart algorithms, PIE is able to calculate where and how many people are present in the building. PIE can quickly transform your building into an intelligent building by using existing data infrastructure.

Increase occupancy by 20% or more

Many organisations lack understanding of how their buildings are being used, resulting in under-utilised buildings and excess capacity in real estate. Creating insights in the actual usage of space can significantly reduce costs as the number of square meters be considerably reduced. Floors or even entire locations can be decommissioned or subleased. With PIE, you have a platform that monitors the occupancy of your building(s) 24/7 and provides you all the relevant information through the Building Intelligence Dashboard. Become data-driven with PIE and avoid discussions that are only supported by feelings, assumptions or static data. From now on, you can base your decisions on data.

“The dashboard allows us to identify inefficiency across our real estate portfolio. At our global headquarters, I expect to improve the utilisation of space with at least 15%”

— Real Estate Delivery Manager, Global Financial Institution

In the tomorrow that we envision there is no waste in the forms of space, time and energy.

Office space that is not used, universities with under occupied classrooms, people looking for work or study spaces, lighting and climate systems that consume energy when no one is using it; in our view, that is not what the future should look like. A building must work with the people. The elevator should already come down before you even get there, and you should already know instantly where you can find a workstation or meeting room available. Thanks to PIE, both human and building do not waste unnecessary space, time or energy.

Quickly find an available workspace

Over 40% of the people who work in a flex-environment are regularly wasting time trying to find an available workstation. As a result, these people lose precious time and energy. This and the frustration that comes with the lack of information are history when using PIE. Thanks to the different applications that leverage PIE data, such as mobile app Spot or kiosk app Wally, employees of your organisation get real-time insight into the occupancy. This way, they can instantly see where they can find available workspaces. Offer your occupants insights that help them to become happier and more productive!

Use what you already have

The philosophy behind PIE is that we first make use of what is already present in your building. WiFi is the primary source of data, from which we calculate where mobile devices are located in the building. A kind of GPS, but indoors. This will take you from 0 to 90% within no-time. Other data source that can tell us something about where or how many people are inside the building can also be integrated into PIE. These could be a access control, bluetooth beacons, or workspace sensors. Everything that is already available in your building and contributes to the accuracy or enrichment of PIE is something we are keen to integrate!

“Due to the scalability of the platform, we plan to further roll out PIE across our global portfolio of over 1 million m2, allowing us to increase occupancy rates and decommission space where possible”

Creating a sustainable world requires intelligent buildings.

At Lone Rooftop, we believe that intelligent buildings can only exist if the interaction between the user and building is optimal. If the building “knows” where people are, all processes that waste space, time or energy can be optimised. PIE sends data to all relevant systems and applications. Use PIE and build a sustainable world together.

Reduce energy costs, increase sustainability

In today’s world we shouldn’t be wasting energy. But why is the light then still switched on in empty rooms? And why are the climate systems in those areas still enabled and consuming energy? Research shows that office buildings waste about 30% of their total energy costs on Climate and Lighting systems that are poorly adjusted to the actual usage and occupancy of the building. PIE connects with your Building Management System so lighting and climate can truly become smart and adaptive based on occupancy data. Is there no one present on a certain floor or zone? Then the lights shouldn’t be turned on there either.

PIE enables you to reduce energy waste.

What are the other benefits that PIE offers?

By bundling all data sources into one single platform, you can immediately take advantage of the power of PIE. All data is centrally stored and managed, allowing other applications and systems to easily access the data through the API. PIE also contains all intelligence when it comes to calculating the occupancy and information of the building. This means app developers don’t have to develop that intelligence or integrate other building information and can fully focus on the functionality of their apps. New apps can therefore easily be developed and added to the PIE store. Another core attribute of bundling all this data is that our growing team of data scientists can discover correlations between the different data types. Using self-learning algorithms, PIE will then improve and enrich the accuracy and outcomes of the platform. This is how you can fully utilise all the data and intelligence that resides inside your building!

Why PIE?

With the rise of the Internet of Things, the amount of available sensors is growing exponentially. This makes it harder to make a choice, and at the same time, you want to do it right at once as the accompanying investments are usually very large. Will you go for workplace sensors or rather BLE-beacons? Or perhaps footfall counters or sensors that use computer-vision to calculate the occupancy?

We at Lone Rooftop have the philosophy to start by using what you already have, as that will determine if and where you will need additional sensors for specific use cases or improved granularity. With PIE, you’ll transform your existing WiFi network into an intelligence system that measures the occupancy. This means that you can instantly make your building intelligent just by implementing a piece of software. Compared to a full sensor implementation this is:

  1. Extremely cost-efficient
  2. Quickly implemented
  3. Providing up to 90% of all movements and the occupancy of your building

From there on, the Building Intelligence Dashboard will provide you with the exact data to decide where you might want to improve accuracy or granularity. This allows you to add sensors or other data sources in a very targeted way, saving both time and costs.

Without the additional investment of implementing thousands of sensors, PIE ensures that accurate data can still be gathered about how our buildings are being used. The biggest advantage? The full implementation only took a few weeks 

— Joris Fortuin, Head of Integrated Facility Management, Wageningen University

Is it difficult to implement PIE?

PIE is a cloud-based software platform that makes a connection to your existing WiFi network, meaning the implementation of PIE is not difficult and typically won’t require much time and resources from your IT organisation. PIE does not interfere with your WiFi network either, as our technology only uses the ‘listening’ mode of the WiFi Access Points so it doesn’t transmit anything. Additionally, Lone Rooftop has official partnerships with the leading network vendors Cisco and HPE Aruba. This ensures we have all the expertise, support and resources to successfully implement PIE at your organisation!

Your buildings can be intelligent today, why wait?
