Air Quality – an indicator for modern building concepts

The quality of the supplied air to each room as well as the energy efficiency of the airhandling-system is the crucial factor of success for modern building concepts.The air quality is very important for spaces and rooms where people working in, but also of high importance concerning production, manufacturing and process engineering.
The quality of air is not just a “soft factor” as a matter of wellness. The quality of air has been proved to be a very hard economical factor. Moreover, better quality of the supplied air in buildings leads to enhanced productivity.
A pro-active influence and control of air quality is a very urgent task to be solved regarding air conditioning in buildings. With an adequate air-quality-control-unit a very high standard of energy efficiency can be achieved. That way, for those who are using an air-quality-control-unit in combination with an efficient air-handling-system the ecological benefit, but especially the economical profit, will be excellent.

Human being in the centre of attention – on-demand air quality management

Even though we spend more than 80 % of our life-time in buildings, there still isn’t paid enough attention to the supplied air quality. Up till now, constant ventilation or CO2 sensors were used as an indicator of air quality,with dissatisfying results. Neither a better air quality could be reached nor could less energy-demand be achieved. The concentration of carbon oxide in the room as an indicator is improper, because the emissions and smells caused by varnish, carpets or furniture are not taken into consideration. With the AL-KO AirQualitizer for the first time it is possible to measure the actual air quality. The AirQualitizer realizes an ondemand air flow volume management, which is based on the actual needs of the user and staff. With the AirQualitizer an operation of the entire air handling system with significantly less energy-demand will be achieved.

Optimized air quality in buildings
is valuable for the staff and their companies

Create your climate –
with the AL-KO AirQualitizer you can have the best climate you really wish

Is your air quality great
Do your employees really feel comfortable
Are they able to provide their best working performance
Air quality is a matter of subjectivity. Nevertheless, all people in rooms and offices suffer by the fact that they are not able to establish their climate. The so-called “sickbuilding-syndrom” caused by the circumstances mentioned, impairs to the health,motivation and working performance of the entire staff.
The quality of air and the possibility to provide the best working performance has a direct link with emissions and smells and its concentration in the building.

Effective air control with
high-sensitive sensor technology

Our special sensor- technology called “LUQAS” detects and evaluates all encumbering emissions and smells – contrary to normal CO2 – sensors, which only are able to detect CO2 – emissions. The detection of emissions and evaluation of air quality has been monitored and proven by the scientific institute “Steinbeis transfer-center sensor-technology and new technologies”.
The signals generated by “LUQAS” will be transmitted via BUS- technology to the air handling unit. By adjustment of the air condition and the air volume, an individual demanded air quality will be created.
Within extensive tests it has been ascertained that “LUQAS” nearly detects and evaluates like the human perception.

The AirQualitizer – quality manager
and financial optimizer

With the AirQualitizer the staff and users are able to customize their air quality and their comfort. A better quality of air enhances motivation and productivity. More productivity increases the economical success.
The AirQualitizer adjusts the air-flow-volume according to the actual demand in every room. That way, the AirQualitizer reduces energy-costs for air conditioning significantly and once more increases the economical return.

Reduce your entire energy-costs about 70 %

With the AirQualitizer you will have a strong hold on your energy-costs

The adjustment of air-flow-volumes by on-demand is the key to manage your energy-costs.
The power consumption of the entire ventilation system will be reduced by minimizing the pressure-losses within the entire air handling system based on reduction of air-flow-velocity.
Besides operation times and individual requirements, the basis to minimize energy-costs is an energetically optimized air-handling-system evaluated by a “life-cycle-costs-analysis” (LCC). Every part should be aerodynamically optimized.Moreover, heat-recovery units, heating and cooling units as well as pumps and flow control units should operate with the highest mode of efficiency possible.
The most decisive criteria will be the efficient interaction within the entire airhandling-system. An evaluation of operating costs expected during the life-cycle can be generated by the AL-KO Software “LCC-optimize”. Based on the data provided by “LCC-optimize” the decision for the air-handling-system with the lowest “life-cycle-costs” can be made.

The AL-KO AirQualitizer communicates via building-automation-system with the air-handling-unit on basis of evaluation of air quality. Air-flow-volumes and temperature can be affected by the staff and all users anytime directly in every room with the AirQualitizer.
The management of mode presence/absence and loadings allows to supply rooms with less people with a reduced and adjusted air-flow-volume. The thermal energy that will be saved can be supplied to rooms with more presence of people and higher demand of air conditioning. The AirQualitizer assures a customized allocation of air-flow-volumes within the entire building at exactly the same or even a lot less energy demand.
With the management of air-flow-volumes by the AirQualitizer in combination with a life-cycle-costs-optimized air handling unit the entire costs for air conditioning will be reduced about 70 %.
