3 Oxygen gives me energy. Thanks to SAUTER, I m always at my best. Breathing space Whether you want to work or just feel comfortable, a pleasant indoor climate is essential. That s why you should invest in an advanced room air management system. Temperature, humidity and air pressure are not the only factors the quality of the air is crucial. SAUTER s pioneering technology provides demandled ventilation to optimise air quality and save energy at the same time. The perfect climate for your business When the air quality in a room is good, the people in it feel more at ease and are more productive. The new SAUTER NDIR CO 2 sensor (single-source, dualbeam, dual-wavelength) is ideal for use in low-energy buildings, for efficient ventilation systems and for rooms with constant or changing occupation. These include hospitals, schools, conference centres, concert halls, airports and offices. Wherever reliable CO 2 readings need to be taken, the SAUTER sensor is the answer. A regulation system ensures that the air flow is constantly modified according to demand. The amount of fresh air required depends on the number of people in a room and their activities. The system must be able to control the air flow, using, for example, regulated fans, air dampers and air filters. CO 2 and mixed-gas sensors constantly measure the quality of the air flow. The ventilation can then adapt to maintain the recommended CO 2 concentration in the room. 3

4 Improve the indoor air quality with intelligent room air management More comfort, less energy consumption, lower costs The effects of excessive CO 2 concentration in the air range from reduced attention spans, tiredness, poor concentration and discomfort to increased mistakes and sick days. This means a loss of working hours and higher costs. These effects can be mitigated by precisely measuring CO 2 levels and regulating the ventilation accordingly ppm Maximum allowable concentration (MAC value) Limit for CO 2 concentration at the workplace 2000 ppm Maximum working range of a selective CO 2 sensor according to European directives >1000 ppm Tiredness and lack of concentration become apparent. Errors become more frequent; learning capacity and productivity decrease (CEN EN13779) 1000 ppm Recommended limit for indoor air according to Dr Max Pettenkofer 400 ppm Fresh, natural ambient air German DIN standard : The concentration of CO 2 in offices and schools should not exceed 1500 ppm. 4

6 Healthy air in every room thanks to the VOC sensor from SAUTER You can also minimise VOC content in the air Alongside CO 2 content, VOC content (volatile organic compounds) is also a pivotal factor in air quality. VOCs are emitted by fitted carpets, furniture and so on. At SAUTER, we have VOC sensors that are highly sensitive to these changes in the air. Combined with an occupancy detector and/or a time control system, they guarantee energy-efficient ventilation VOC sensor CO ppm = 10 V VOC/CO ppm = 5 V SAUTER CO 2 sensors Unoccupied period (weekends) 0 Day 1 13:00 Day 1 18:00 Day 1 23:00 Day 2 9:00 Day 2 12:00 Day 2 18:00 Day 2 23:00 Day 3 9:00 Day 3 12:00 Day 3 18:00 Day 3 23:00 Day 4 9:00 Day 4 12:00 Day 4 18:00 Day 4 23:00 Day 5 9:00 Day 5 12:00 Day 5 18:00 Day 5 23:00 Day 6 9:00 Day 6 12:00 Day 6 18:00 Day 6 23:00 Day 7 9:00 Day 7 12:00 Day 7 18:00 Day 7 23:00 Day 8 9:00 Day 8 12:00 Day 8 18:00 Day 8 23:00 Day 9 9:00 Day 9 12:00 Day 9 18:00 Day 9 23:00 Day 10 9:00 Day 10 12:00 Day 10 18:00 Day 10 23:00 Recommended uses: Type of buildings/rooms Non-smoking Smoking Other types of pollution CO 2 sensors Mixed gas sensors (VOC) Schools Gymnasiums Offices/conference rooms Individual rooms Festivity rooms Foyers Kitchens Sanitary areas 6

7 European standards and directives on air quality Air quality is an important aspect of building certifications such as LEED and DGNB. This is because building shells are becoming increasingly air-tight, preventing air from being exchanged naturally. An efficient means of ventilation is vital. The European Community has issued the following standards with regard to indoor air quality: EN 13779: Ventilation for non-residential buildings. Performance requirements for ventilation, air-conditioning and cooling systems EN 15251: Indoor environmental input parameters for design and assessment of the energy performance of buildings, addressing indoor air quality, thermal environment, lighting and acoustics Save energy and money with the SAUTER CO 2 sensor Demand-led ventilation control not only provides an atmosphere in which the room users feel comfortable; it also achieves energy savings of up to 60 percent. This is because faster and more precise regulation leads to increased energy efficiency. 75 to 80 % of the life-cycle costs are operating costs. The efficient room management system from SAUTER will enable you to cut your energy consumption, thus minimising your running costs. The intelligent room automation system will pay for itself in less than a year. 100% Volume flow 80% 60% 40% 20% 0% 2:00 4:00 6:00 8:00 10:00 12:00 14:00 16:00 18:00 20:00 Demand-led volume flow Constant volume flow Energy saved 7
