New WHO guidelines on air pollution – what’s their meaning?

By reducing the recommended heights, existing laws come under pressure – or at least are being questioned. While the European Air Pollution Control Directive largely complied with the previous WHO recommendations from 2005, gaps are now apparent. The EU has already announced a revision and launched the corresponding consultation. Read more

TÜV Süd confirms Hawa Dawa the accuracy of the “indicative measurement”

IoT measurement method meets legal requirements to prove compliance with air pollutant limits. Hawa Dawa has been the first provider in Europe to be certified by an independent state-approved body for the legally prescribed measurement accuracy of its IoT sensor measuring networks. TÜV Süd certifies:  Hawa Dawa achieves the quality objectives of the 39. BlmSchV  (the national implementation of the EU directive 2008/50/EG ).

Dorothee Bär, German Minister of State for Digitalisation: Hawa Dawa provides an important tool for those responsible in cities and businesses

In an interview for RESPOND, BMW Foundation Herbert Quandt, Dorothee Bär, Minister of State for Digitalisation,  said: “The fact that sustainability and digitization can work very well together is also demonstrated by your ‘Tech for Good’ projects. I’m thinking of the RESPOND startup Hawa Dawa from Munich, for example, which makes air quality visible. It provides an important tool for those responsible in cities and businesses to reduce air pollutionRead more

Sources and impacts of, and countermeasures against air pollution

Jakob Smretschnig,  a master’s student of Sustainable Resource Management at the Technical University of Munich supporting the Hawa Dawa software team talks about sources and impacts of, and countermeasures against air pollution. Read more

City of Ulm selects technology of Hawa Dawa

Hawa Dawa becomes part of the project zukunftskommune@bw in the city of Ulm

Hawa Dawa was awarded the contract within the public tender for the procurement of LoRaWan-capable air/climate sensors in the Eselsberg project area in the city of Ulm. Hawa Dawa will install a network of several Sentience air quality measurement devices, develop a comprehensive display from the measured values and feed the data via API into the Ulm data platform, which is currently under construction. The data will be made available as open IoT data. Read more

Hawa Dawa establishes a local network for measuring air quality in the city of Seelze

Hawa Dawa has been commissioned by the city of Seelze to establish a local network of IoT (Internet of Things) measuring instruments. A total of three Hawa Dawa Sentience air measurement devices will provide hourly values for nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM2.5 and PM10) in places identified by the city of Seelze as useful.

In the city of Seelze live 36,000 inhabitants on an area of 54 square kilometres. Seelze neighbours directly to the west on the state capital of Lower Saxony, Hanover. There are no permanently installed public measuring stations in the city of Seelze. Temporary measurements did not show that the official threshold value for NO2 of 40.0 micrograms per m3 was exceeded. Nevertheless, the city of Seelze is aware of the health risks posed by polluted air even below the legal limit and has decided to actively address this problem. The first step is to obtain clarity on the current air quality.

The Hawa Dawa solution for Seelze presents the measured values close to real-time in digital form on an interactive dashboard. Monthly reports provide in-depth insights into patterns and timing, taking into account temperature and wind data. By using Hawa Dawa IoT air measurement devices, Seelze can determine the locations where the measurements will be made, taking into account local requirements. The Hawa Dawa PRO Dashboard used by Seelze enables additional insights on air quality in Seelze to be gained through a heatmap display – after all, information about the places where people are actually staying are crucial.

Karim Tarraf, CEO of Hawa Dawa, explains: “Many smaller to medium-sized cities are in the situation of Seelze, that there are no public measuring stations. The decision-makers do not have up-to-date information on the impact on air quality caused by traffic and other issuers. We believe that local air quality facts are a prerequisite for taking effective action against air pollution and protecting the population. Here, mere measurements are not sufficient, but it is imperative to analyse the data in context. We are pleased to support the city of Seelze in this project.”
