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 ).
In the evaluation, TÜV Süd used measurement data of a period of 12 months. For this purpose, the NO2 (nitrogen dioxide) values measured by Hawa Dawa were compared with the values of an official measuring station.

Podcast: Air Quality Sensor Network in Ulm

Air quality, environmental protection and health are topics that are constantly gaining attention not only throughout Germany, but also in Ulm. With sensors, we lay the foundation for our own urban measurement series at the Eselsberg in the Zukunftskommune@bw project. The partner in the project is the technology provider “HawaDawa”, which was awarded “Digital Startup of the Year” by the Ministry of Economy and Energy in 2020. In this episode, project manager Kai Weinmüller, from the Ulm initiative group Sustainable Economic Development, together with Karim Tarraf, the managing director of HawaDawa, gives exciting insights into the project and previous findings.

Dorothee Bär, German Minister of State for Digitalisation: Hawa Dawa provides and 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 pollution….” In her intro, she referred to the federal government’s goal of taking sustainability and digitization into account in all strategies. According to Dorothee Bär, the German sustainability strategy is based on two principles:

  • use the numerous opportunities of digitization for sustainability
  • avoid risks to people and the environment

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.”

Do the positive effects of the Corona Lock-Down offset the health issues caused by the pandemic?

A deeper analysis for Munich

The COVID-19 pandemic has infected about 13 million people and claimed more than 550 thousand deaths worldwide by 14 July 2020. It has been reported in research that high air pollution may be “one of the most important contributors to deaths from COVID-19”. Studies show a positive correlation between particulate matter and nitrogen dioxide to health damage and, more specifically, to diseases related to the lungs like pneumonia, which makes people suffering from these ailments more susceptible to COVID 19. On the other hand, due to the lockdown measures, significant improvement in air quality has been witnessed. Read more

Hawa Dawa provides data-based decision-making platform to reduce urban traffic-induced emissions in Mainz

Better urban air quality does not need drastic measures – but a meaningful database for decisions

Hawa Dawa has been commissioned by Stadtwerke Mainz with an innovative and result-driven project: creating a sustainable data-based decision-making basis. Hawa Dawa will propose stepped measures to improve urban air quality based on their projected impact on air quality, applying data-based analyses, and forecasts. For this purpose, an intelligent infrastructure for collecting environmental and traffic data as well as a data platform for evaluation is established. Read more

The long overdue paradigm shift towards a healthy, carbon neutral economy starts with cleaning our air

Air quality management – a fascinating lineage

I grew up in Cairo. A city that shows all the typical traits of an emerging economy when it comes to air quality and health. I grew up in a household of doctors, who spent their lifetime researching the delicate relationship between the air we breathe and our health. Here is a paper co-written by my dad for The Lancet Journal on the “Effect of nitrogen dioxide and sulfur dioxide on airway response of mild asthmatic patients to allergen inhalation” written back in 1998. So imagine you grow up seeing and hearing about the “Black Cloud” of Cairo and the rise of patient visits in my parents’ clinic around the dinner table. Or discussions on best treatment options for patients during the long drives towards the Egyptian Red Sea coast with its windy fresh air. Thus, I always understood the topic of air pollution within a context – the context of bad health indicators, exacerbated symptoms, increased healthcare expenditures and overall reduced life quality.
