Channeling the flow of ideas

 

The temperature has started to drop below 0 in Umeå at nights, but we are keeping warm this busy autumn. We arranged the Civitas Forum in the beginning of September, which generated many new projects and contacts. We inaugurated the new hub for our e-buses and also the second bike-hub for our e-cargo bikes. A new 5G-testbed is being set up in our innovation area (the first full scale 5G-testbed in Europe). This includes a lot of new partnerships possibilities to test innovative smart solutions. And last week we were selected as finalists in the European Capital of Innovation – yes!

In Ruggedised we are two years into the three-year implementation phase. We are well on track with the construction and installations of the technical parts. As our partners always point out “the challenge is not the technique – it is how we work together to get the most out of it”. It is true, but I also notice that the longer we work together and get to know each other’s businesses and operations, there is also a newer ending flow of new ideas and projects. Our challenge right now is how to find time to manage the creativity and not lose good ideas. Does anyone have a solution to this?

Solution n°U4 – Smart Building control

Many buildings today don´t have a system in place for automatic control of ventilation, heating, cooling or lighting. During daytime we have rooms that we use, and some rooms that we don´t use at all. Even though we don´t have detected any presence in the rooms the ventilation system is still at 100 %. The same happens after business hours. We want to have a smarter building than this, and we want to provide the possibility for the building to become more energy efficient.

For example, during daytime, if the control system has not detected presence in the room and we are not using it, the lighting should be dimed down or off, and the air flow should be at a minimum. We also want to move people to certain areas in the building in order to maximize the energy efficiencies of the building. This is a collaboration with the University and the solution U9 (Demand Side Management).

A control system like this often demands advanced technology. To be able to handle this information from a system like this, you need to have the necessary support system in place but also the know-how. Our organization has decided to have this resources and expertise in-house. For us, to have this knowledge about our buildings and tenants, is very valuable because we want to provide a high service to our key client which is the University.

This “smart” control system can provide us with information such as (a few examples):

- How many people are in the building or a specific room.

- Data about airflows, which will help us if we have a new construction or refurbish a building that we will use almost the same way.

- Data about room temperatures. We can also visualize the energy consumption in each room by measuring heating, cooling, fans etc in each room.

Solution n°U9 – Demand Side Management

Our analysis of the occupancy pattern of the buildings in the Umeå University campus suggest that it is possible to reduce energy use in buildings if reliable information on occupancy is available. Moreover, occupancy related information would give insights on how a building is used which would help to optimize the building services such as cleaning.

Occupancy sensors are now being installed in sample offices, corridors, conference rooms and lecture rooms. The occupancy sensors include the PIR sensors, desk sensors and sensors that use embedded logic for detecting presence in a room. The parameters that will be monitored include motion, light and temperature. Apart from these, a few sensors that could detect CO2 will also be installed in selected places. A detailed monitoring of the building use will follow which provide information on how the building is currently used and what can be done to reduce the energy use, optimize the building service and also notice whether any action need to be taken to improve the security aspect.

A comparative study of the offices could provide additional information on correlation of energy use and the intelligent building control system. A comparative assessment of occupancy detection by different type of sensors, for example, PIR sensors, desk sensors, CO2 sensors will also be carried out. Also, we will cross verify the information from occupancy sensors in the lecture rooms with the information in the booking system for rooms to see possibilities to improve the booking system for rooms to optimize the energy use and cleaning schedule.
