The Blue Building Office and Laboratory in Sharjah, United Arab Emirates
Besides being officially registered as a Sharjah Airport International Free Zone company, in 2014, with a special license of His Highness Sheikh Dr. Sultan bin Muhammad Al Qasimi, Blue Building Holding and Blue Building Foundation (FZE) have completed the construction of their office in Sharjah, Al Atain.
This office building currently serves as a model building for the Blue Building Concept and has implemented its concept with healthy and recyclable materials, unique cooling techniques with airtight construction and super insulation. This will lead to new standards of energy conservation superior to those known from passive-house buildings. To achieve the goal, a thermal simulation was developed that allows calculation of the required energy flows and the cooling capacity to be installed.
However, there was something very “special” about the Sharjah Office and Laboratory Building
In a closed room, one person can raise the CO2 level to 1000 ppm within 45 minutes. According to Max von Pettenkoffer, this is the maximum amount for a healthy living.
The Blue Building controlled air circulation has demonstrated an increase in employee performance. Due to the carefully calculated ventilation rate, the Blue Building Foundation has had only two absences due to illness (3-4 days each) in six years with ten employees.
The Blue Air Purification System BAPS (controlled air circulation) has run from 2014-2020 (until relocation to Scotland) in the undersigned’s Sharjah office without any problems. When his laboratory and office was built in 2014, no one seriously thought about the following fact: The stationary controlled air circulation system installed in the building was not only able to remove bacteria, viruses and pollen from the air. Besides reducing dust particles, eliminating pollen and bacteria, it has also captured most of the viruses (99.9995%). This system was able to reduce CO2 levels indoors by up to 47.5% compared to outdoors; a globally unique result. Values of 218 ppm carbon dioxide were measured, while outside values of 415 ppm carbon dioxide were usually measured. From 2014 until 2020, the air quality measurements were performed 24/7; the lowest value achieved indoors was 218 ppm CO2 while the CO2 level outdoors was 415 ppm.
In the years 2014-2020, countless measurements were taken on this system regarding air quality, air humidity temperature but also CO2. These measurements clearly reflect that the colder the air temperature (indoors or outdoors), the higher the CO2 value in mg/m³.
In 2014, this office building was certified with the "Gold Label Status" by Joachim Schubach, publicly appointed and sworn expert in association with "Die Gesellschaft für Nachhaltiges Bauen" (DGNB) which is "The Association for Sustainable Building" in Germany, providing that our concept is the leading representation for sustainable Building.
To cool down the rooms, water pipes are installed in the ceiling. This system of quiet cooling is much healthier than the vents of the normal coolers. This system is working with radiation. A pleasant room temperature is achieved without draught; it is silent, healthy, clean and without any allergen burdens.
The incoming outdoor is being cooled down and cleaned from pollutants and dust particles; the used air inside the house will be exhausted. The controlled air circulation system is increasing the rate of oxygen and decrease the rate of CO2. With the Blue Building Cooling System, we have in average a relative humidity of 50%; the system is silent with a controllable temperature.
