NV Comfort™ regulates and adjusts internal air quality using an intelligent, computer-controlled system that harnesses the natural forces created by temperature differences outside and inside the building and by the effect of wind around the building.
Get in the comfort zone
WindowMaster, Europe’s largest provider of natural comfort and smoke ventilation solutions, has launched an innovative new indoor climate solution for small and medium-sized buildings. Called NV Comfort™ their new control system enables an optimal indoor climate through consistent pure natural ventilation. At the same time it can save enough energy to significantly reduce CO2 emissions.
The programmable and intelligent system automatically ensures that a window is in the position that will create and maintain the desired internal air temperature and closes the window automatically if it starts to rain or the wind blows too heavily. NV Comfort™ is well suited for new buildings and renovations for small and medium sized buildings such as schools, offices, healthcare facilities, hotels, exhibition buildings, sports centres and other buildings where there is focus on reducing CO2 emissions.
International research shows increased productivity and learning capacity of up to 15 per cent with the right indoor climate. Natural ventilation prevents headaches, fatigue, irritated eyes and concentration difficulties. Since people spend up to 90 per cent of their time indoors, internal air quality is very important. Because 40 per cent of energy consumption in Western Europe is used in buildings, there is renewed focus on indoor climate solutions that consume minimal electricity and thus emit less CO2. An indoor climate solution with NV Comfort™ can provide that.
NV Comfort™ is based on WindowMaster’s established NV Advance™ system for management of natural ventilation in larger projects, such as schools and offices. Like the NV Advance™ control system NV Comfort™ regulates and adjusts internal air quality using an intelligent, computer-controlled system that harnesses the natural forces created by temperature differences outside and inside the building and by the effect of wind around the building. It has fewer features than NV Advance™ and is therefore ideal for smaller projects with a limited number of zones.
NV Comfort™ controls façade and roof windows so that they automatically open and close by incremental amounts on the basis of individual fixed values for the desired room temperature and CO2 levels, as well as measurements of external temperature, rain and wind speed. Setting the desired room temperature and CO2 levels can be done individually for each room from one central location in the building via the NV Comfort™ touch screen.
Patented MotorLink™ technology enables the NV Comfort™ system to register the opening distance of each window as well as quietly opening and closing them. Safety has been a focus as well. The windows will stop and open again if they meet an obstacle during the closing cycle. NV Comfort™ intelligently monitors windows to prevent entrapment as an integrated function of the motor and control system. It can significantly reduce the risk of possible injury while windows are closing.
If an object becomes trapped in a window and prevents it from closing the amount of current drawn by the motor instantly increases. This is detected by the micro-processor, which immediately reverses the motor to release the window, therefore reducing the possibility of serious injury. The system can be retrofitted on many existing windows as well as being installed on new buildings. It can operate on a broad range of window types, including top and bottom opening, sliding and parallel opening. The system can also be used on windows for heat and smoke ventilation.
Richard Arnott, UK and Ireland market manager for WindowMaster, says:
“It is always pleasant to have fresh air coming in through the window. But it can be inconvenient having to adjust the window constantly to maintain the desired temperature or to keep out wind and rain. WindowMaster’s compact and intelligent new system automatically ensures that windows are in the required position to provide the optimal internal air temperature and air quality and it always remembers to close the window if it starts to rain or the wind blows too heavily.”
