Kabona is a company which works with energenious energy building automation and the company’s head office is locatedin Borås, Sweden. Kabona was founded in 2001 and has long-standing and solidexperience, which has formed the basis of our innovative and energy smartproduct Ecopilot. Since 2012 Kabona has been owned by Investment AB Latourwhich is registered on the Stockholm Stock Exchange under Large Cap.
Project property Kuggen, Lindholmen Göteborg – independent evaluation of Ecopilot in amodern office building
The project’s aim is a thorough evaluation of special functions for integrated control of heating, cooling and ventilation, specifically adapted to utilise the building’s thermal inertia.Kabona refers to a long series of projects where Ecopilot has resulted inenergy savings of 25%, with retained or improved quality of the indoor climate. However, no independent evaluation of the system has been conducted yet, whichis the aim of this project.
About the building
The building Kuggen is an office building of 4,898 m2 divided on 5 floors and was put into operation in 2011. From the start, even before Ecopilot, the building had good energy performance and has been certified in accordance with the EU programme for energy-efficient building, Green Building.
Installation of the new superior control system, Ecopilot, was conducted on 27 August 2014 and this evaluation focused on how this has impacted the indoor environment, energy consumption and operation.
The building’s performance before Ecopilot
According to the energy statistics of 2013from Göteborg Energi, Kuggen’s energy consumption is 37 kWh/m2 peryear for heating (temperature corrected) and 9 kWh/m2 for districtcooling. In 2013 the consumption of property electricity amounted to 27 kWh/m2year and business electricity to 28 kWh/m2. The results of consumption before and after Ecopilot are presented under conclusion below.
The evaluation was performed by an independent party, CIT Energy Management AB, without links to the supplier of Ecopilot. In order to ensure correct installation and operation of the system,CIT collaborates with both Chalmersfastigheter and Kabona. This evaluationcovers six months (the time period September 2014 – February 2015).

Owner approach of sustainability
Kabona delivered energenious building management system, Ecopilot, into this building.
The building was build commissioned in 2011 and consists of 190 "cogs" where each rack corresponds to an office module. The building has 5floors and floor plan area increases with the height of the building in order to create shade for the bottom field. The top floor is provided with a 98m2 mobile sun blocking system to follow the the sun's movement. Rack is designed with a clear sustainability profile with good energy and has been marked in accordance with EU programs for energy-efficient construction (Green Building) and certified in accordance Environmental Building Class gold. The building has a circular shape and the overall temperate area (Atemp) is 4898 m2. The facade consists of display tiles and the windows are triangular to reduce window area but allow natural light deep into the building.

Ecopilot is a new system with integrated control of ventilation, heating and cooling. Ecopilot functions brilliantly, both for new production and existing properties where we over-modulate existing BMS. The system particularly takes into account heat storage in the building and thereby counteracts the need of, in a short duration, alternating from heating to cooling, and vice versa. Ecopilot optmises energy with respect to internal loads, weather forcast, indoor temperature, wind impact and sun insolation.
They are very happy about the huge enrgy savings that we have accomplished
The conclusions which could be drawn are that the requirements for the indoor environment are fulfilled with Ecopilot and that with the new control you have greater variations in the room temperature and air flow, especially during the summer drop, but that the greater variation takes place outside the comfort periods.

Reasons for participating in the competition(s)Our unique product – Ecopilot
Ecopilot is a new system with integrated control of ventilation, heating and cooling. Ecopilot functions brilliantly,both for new production and existing properties where we over-modulate existingequipment. The system particularly takes into account heat storage in thebuilding and thereby counteracts the need of, in a short duration, alternatingfrom heating to cooling, and vice versa. So the point is that the systemresults in “calmer” control, which in turn leads to reduced energy consumption,lower heating and cooling power needs and retained or improved quality of theindoor climate. There are currently approximately 320 installed Ecopilots. Formore information about the product and our customers, please logon toecopilot.com
