Commercial properties account for around five percent of global electricity consumption. Consuming electricity at the same rate as in the past is costly for the building owner and the leaseholders, but even more so for the external environment. With the aid of demand-controlled indoor climate we keep costs down, while reducing our carbon footprint.
We are currently witnessing a global and unprecedented trend: New investment in electricity generation is increasingly being made in renewable energy sources. This is a welcome new direction, but has to speed up if we are to cope with two degrees of global warming.
We all face the challenges of reducing man-made impacts on the global climate. There is huge scope for achieving the energy transition now that the technology for significant energy efficiency is readily available. One way is to improve the energy performance of our buildings.
In order to meet both energy and comfort requirements, the solution is typically demand-controlled ventilation (DCV). This is where we ventilate each room exactly as much as is needed; neither more nor less. DCV involves occupancy sensors to detect whether anyone is present in a given room, and to detect the temperature and air quality along with control systems and products that adapt to needs as they arise.
The savings potential is vast, above all in office buildings, teaching rooms and hotel rooms where space occupancy varies immensely between low and peak loads.
With DCV, buildings can meet strict requirements for energy performance. Up to 80 per cent of electrical energy and 40 per cent of heating and cooling energy can be saved by using demand-controlled ventilation as compared with constant air flow and temperature.
Other positive effects are that smaller units and dimensions can often be used for ventilation, heating and cooling because the air flow and temperature can be lowered as compared with constant flow and temperatures. The flexibility is also greater in the event of future building alterations or changes in how premises are used.
With the new WISE we’ve taken DCV up a level. Because WISE caters for demand-controlled indoor climate (DCIC), meaning not only ventilation, but also air- and waterborne heating and cooling. Its flexibility gives you all the scope you need for combining products right down to room level. Developed with the specific aim of simplifying the entire building process, WISE takes you every step of the way from project planning to installation and commissioning, and ensures the realisation of what might otherwise have remained a sketch on the drawing board. WISE basically delivers comfortable surroundings for building occupants through demand-controlled adjustment of air, heating and cooling. And does so with the lowest possible energy consumption.
