Haltia’s facilities can be adapted to a wide variety of uses, and similar adaptability has been the goal of electrotechnological solutions. The consumption of electricity is lowered by the geothermal heating system that significantly reduces the amount of electricity needed for heating and cooling. The aim for the future is for Haltia to be as energy self-sufficient as possible due to the geothermal and solar energy solutions used. If mains electricity is needed to supplement the energy consumption, electricity produced from renewable energy sources is purchased for the building.
Smart lighting adjusts itself
Most of the electricity in Haltia is consumed by lighting and presentation technology. The building is designed so that natural light from the windows can be used as much as possible, for example in the lobby and the restaurant. In contrast, natural light is prevented from entering the exhibition facilities in order to minimize the power requirement of the lighting system. LED lights are used in the outdoor lighting at Haltia. Motion detection and presence detection reduce the power consumption of indoor lighting. Motion detection is used for example in the auxiliary rooms, toilets and corridors. When there is no movement in the corridors, lighting is dimmed to about 10 per cent of the standard level, and returned to normal when necessary. It is not advisable to turn off the fluorescent lamps completely, as that would shorten their service life. Dimming reduces electricity consumption and extends the lamps’ lifecycle. The lighting at staff workstations is controlled by presence detection, which is more accurate than motion detection and even recognizes the movement of fingers on a computer keyboard. Energy-saving equipment has been selected for the exhibitions at Haltia. The centralized, remotely controlled exhibition control technology enables the control and switching off of all exhibition equipment when not in use.
Elevator braking energy recovered
One elevator serves the entire building. The elevator’s braking energy is recovered into the building’s electrical network for immediate use as needed. The energy recovered from the elevator could be used to run three washing machines full of laundry machines every day, all year round.
Sunlight from the socket
In the future, after further advances in technology, the aim is to build solar panels that produce solar energy to be converted for use in the power grid. The solar panels will further increase Haltia’s energy self-sufficiency.
A backup generator keeps Haltia running in case of power outage
Because Haltia is built of wood, a backup system secures the operation of its extinguishing system in case of power outages. A diesel-powered backup generator ensures the functioning of the fire extinguishing system in the event of a fire. However, the backup generator does not stand idle at other times, either, as it can be used to supply electricity into the building’s network during so-called normal power outages, that is, when there is no fire. That is why Haltia’s operations can continue almost as usual even during power outages: after a 15-second delay, the backup generator starts running to provide power for the lights, exhibition technology and other functions in the building to almost 100 percent.
