vs. ensto today | SOLUTIONS 10 Air Climate Ensto Enervent is moving from “heat recovery” to “indoor climate control.” Enervent air quality offers all these benefits: • Comfort: Indoor temperature is not the same as indoor climate! The difference between cooling and de-humidifying is significant in Nordic climates. For example, even if it's +11 C outside, rain will produce humidity up to 96 percent. This moisture needs to be removed from the air. • Structural integrity: Moisture in buildings means the structure suffers physically and devalues economically. • Health: Mold can harm occupants’ health and require expensive facility renovation within five years. Enervent keeps buil-dings dry. • Sleep: High CO2 means you wake up tired. Outdoor air is typically 300-400 ppm (CO2) and good indoor air is less than 750 ppm. Over 1,500 ppm is not healthy. Ensto Innovation Award 2014 goes to Enervent EnergyBus Ensto Innovation Award is an annual Ensto internal global innovativeness contest open to all Ensto people. This year’s winner of the EIA Trophy, Enervent EnergyBUS, is a solution for total energy efficiency in indoor climate. Excess heat or coolness in the building is stored in an energy bank and used at demand at another time. Thus the need for purchased energy is minimized. The warmed water in the tank can be used for heating or as domestic hot water. EIA jury praised the winning solution particularly on its holistic view and unparalleled energy efficiency. Anders Nyberg with his Pallas system. Almost two years later, Nyberg says the Pallas system has delivered. “When you buy anything you have to take into account that part of what you hear is sales talk. But this product has exceeded my expectations.” And he sees application for it elsewhere. “This is something people should think about in apartment build-ings. For example, if one unit goes out in a five-story building, as long as there’s electricity you can still heat that floor with the other units.” Ensto Enervent’s Riekkinen says Pallas family products are suitable for spaces up to several thousand square meters in size, and its modular capabilities mean it can handle even 40-story buildings, as well. And not only in Nordic climates. Hot and humid, too In humid climates the traditional solution is to pump in cool air, which consumes huge amounts of energy. But simply removing the humidity with an Enervent system has advantages. First, it is cheaper, since low humidity means the actual temperature can be higher yet the indoor cli-mate will still feel comfortable. Second, one gains the added benefit of producing water. “By removing humidity from the air with our system, 300 liters of water per day can be generated from a single home in a place like Hong Kong,” says Riekkinen, “You can use that to flush your toilet or water your garden.” Indeed, anywhere indoor climate is an issue could be a market. “We’ve started in Hong Kong,” says Riekkinen, “and recently exhibited Pallas in Shanghai and Macau.” “We plan to be faster and more flexible in listening to markets than any company has been,” says Riekkinen, who envisions Enervent conquering far-flung markets with climates dissimilar to Finland’s. “Enervent – Powered by Ensto.” Enervent EnergyBUS solution
