Gdansk Science and Technology Park (GPNT)
Gdansk Science and Technology Park is a vibrant business and technology center where dozens of companies have found a place to run their business.
Although these are relatively new facilities (commissioned in 2011-2014), the owner of the complex saw the potential to reduce heating costs by installing an intelligent thermal management system. The tender for the design and installation of such a system was won by Kiona, offering our Edge-solution.
About the project
The modernization project at Gdańsk Science and Technology Park focused on two buildings, A and B, with a combined usable area of 25,300 m². These buildings have a heated area of 9,800 m² and 9,140 m².
The buildings were originally equipped with a traditional control, regulation, and heat management system based on the current outdoor temperature and the heating curve. The park uses heat from the municipal installation for central heating, ventilation, domestic hot water, and process heat.
As part of the modernization plan, the existing heating system that relied solely on measuring the outdoor temperature was scheduled to be upgraded. The new system takes into account various factors such as the forecast temperature, expected sunlight, precipitation, humidity, and wind speed. Additionally, it constantly monitors the internal temperature, the building's thermal performance, and the current ambient temperature. This allows for more precise control of the heat distribution.
Installation
Another requirement for the new heating management system was that all its elements should be fully compatible with the existing control system at the substation. The goal was to avoid any changes to the substation's technological setup. In addition, the new system should also have the option to operate traditionally based on the current outdoor temperature if there is no weather forecast available.
The Edge system, based on IoT technology, is a solution for controlling, monitoring, and optimizing heat consumption, satisfying all the requirements of the park. Thanks to the "light" architecture, based on a wireless network (WM-Bus, Wireless Meter-Bus), the installation work lasted only two days and did not interfere with the day-to-day operations of the park itself or its tenants.
Achieving energy goals
The solution implemented at the Gdańsk Science and Technology Park consists of several basic elements: a device controlling the operation of the heating substation, a network of internal temperature and humidity sensors, a gateway that facilitates communication with cloud services, and the WM-Bus network, which connects all the network elements to the gateway.
To monitor the temperature on the supply and return pipes (which distribute heat from the municipal network to the buildings), two wireless, battery-powered contact sensors were installed.
- In buildings such as GPNTs buildings, heat consumption is usually reduced by about 10% after installing Edge.
- This translates to a fast return on investment, with the savings covering the total cost of the system within just a few months, especially given today's energy prices.
The best part is that these savings are almost immediate, so building owners and managers don't have to wait long to start seeing the benefits.
