Our Experience In Indoor Air Quality & Human Productivity

Insufficient ventilation causes human-produced carbon dioxide to build up indoors, decreasing employee wellbeing and productivity substantially. With accurate CO2 measurement, both energy efficiency and employee well-being can be achieved simultaneously. Studies indicate that better indoor air and ventilation have a positive impact on productivity. The Continental Automated Buildings Association (CABA) conducted a comparison between better buildings and other employee strategies, like workplace health programs and bonuses. With a meta-study of 500 different studies, they found out that better buildings increase productivity by 2–10%. The Federation of European Heating, Ventilation and Air Conditioning (REHVA) states that decreased ventilation lowers productivity, for example, typing speed, by 10%. The US Green Building Council commenced a meta-study in 2003 and concluded that delivery of fresh air and reduced levels of pollutants improve productivity by 11%. According to the analysis of the Carnegie Mellon University, better ventilation improves productivity by 3–18%. To sum it up, the productivity gains of better ventilation range between 2% and 18%, with many studies.

Customer Cases

Throughout our 80-year history, Vaisala has succeeded together with our customers. From helping with the preservation of the most valuable painting Mona Lisa at the Louvre Museum in Paris to the invaluable French, English, and American stained glass windows at St Patrick’s Cathedral in New York City to controlling ventilation and air conditioning at metro stations for the comfort of commuters, our humidity control instruments are selected because they are simply the best.

Vaisala Helps to Preserve Mona Lisa

Inside the Louvre, Da Vinci’s 500-year-old Mona Lisa hangs in a glass display case preserved from the effects of time and the environment. In 2005 it was discovered that condensation was degrading Da Vinci’s best-known portrait. The painting was moved to a new case, a tightly controlled microclimate maintained at 21°C and 50% humidity. “As a normal Louvre visitor, you cannot even imagine the complexity of the installation. ”Wilfried Gesbert, Climate Engineer for Cofely Axima. The new bullet-proof non-reflective display case was tailored to preserve the painting, as was the lighting and air treatment system. Technology meets Artistry.

Gesbert and his fellow climate engineers assigned to ensure preservation of the painting installed two Vaisala HMT333 temperature and humidity transmitters to monitor conditions inside the case. They required an instrument that was not only precise but failsafe. The Vaisala HMT333 devices now share the display case with the portrait, hidden from view, to ensure conditions are maintained.

IT-company Infosys Chooses Vaisala’s HVAC Sensors

Infosys is the second largest Indian IT consulting company with 200,000 plus employees and revenue of over USD 10 billion. With headquarters in Bengaluru, the company has its development centers in over 16 locations across India and one campus in China. Currently Infosys is using Vaisala’s HVAC sensors in all its projects for measuring temperature, humidity and carbon dioxide, namely HMD110, GMD20, GMW90 series, and HMW90 series. To measure the same parameters outdoors, they use the HMS112.

The significant reason for choosing Vaisala sensors for Infosys was the 5-year stability specification for the products. Especially for humidity and CO2 sensors, which otherwise drift frequently, this reason is very important. “We find that Vaisala is unique in this sense. The 5-year stability specification provides the kind of confidence and trust the customer looks for in any product. In the last 3 years we have been using the products, we have received timely support from Vaisala and are quite satisfied with the product quality,” concludes Mr. Makkar.

Vaisala Equips the New Children´s Hospital in Helsinki

Vaisala was the honorary in-kind donator for the new children’s hospital that was built in Helsinki. The opening of the hospital took place in May 2018. The importance of good air quality in a hospital environment is evident, as high-quality indoor air ensures the well-being of the patients and a safe working environment for the staff. Good indoor air also helps the little patients to recover faster. Vaisala contributed humidity, temperature, and carbon dioxide measurement instruments to the hospital.

The tissue bank stores vital spare parts

The tissue bank of the New Children’s Hospital is part of the hospital’s operational unit that handles the treatment, preservation, and distribution of human tissue. The most common materials in the tissue bank are blood vessels, such as lower extremity veins and arteries, cardiac valves as well as parts of the pulmonary artery and the aorta. Majority of the stored tissue is used in the in-house operations of patients suffering from congenital heart defect. The tissue bank has been a significant part of the Operating and Anesthesia Unit of the hospital already since 1973. The new facilities made it possible to install new technology to control the conditions of the tissue bank. “Without a high-quality tissue bank, we would have to order the heart tissue transplants from abroad or the children would have to be sent to have surgery abroad“, says Sari Tähtiharju from the tissue bank of the New Children’s Hospital. “Approximately two heart tissue transplants are used per week, and they help treat about 100 children annually”, Tähtiharju concludes.

Continuous monitoring ensures the quality of the tissue transplants

The critical parameters in the tissue bank, such as temperature, humidity, and air quality, need to be monitored and observed continuously. The Continuous Monitoring System guarantees constant control of the conditions and helps to ensure that the conditions related to the treatment and storage of the tissue transplants are appropriate, considering the consistency and cleanliness of the tissue. The parameter values need not only be controlled but also saved in order to prove that the conditions have been in line with the required storage conditions. Tissue banks are regulated by Finnish and EU legislation and overseen by the Finnish Medicines Agency Fimea. Vaisala’s Continuous Monitoring System was developed for the needs of pharmaceutical industry from the start, thus the system corresponds to hospitals’ hygienic and maintenance guidelines. It also complies with GxP regulations and standards, such as FDA 21 CFR Part 11, EU Annex 11, and ICH. Vaisala’s viewLinc system controls the conditions, ensuring consistent data, browser-based monitoring as well as quick and easy reporting. In addition to accurate measurement data, the system alerts personnel, if the conditions exceed permitted values.
