Providing added value for citizens with environmental data

Hawa Dawa wins Leipzig Smart City Challenge “Urban Environmental Data – View & Understand

Hawa Dawa won the Leipzig Smart City Challenge “Urban Environmental Data – View & Understand”. The approach presented by Hawa Dawa to the question “How can urban environmental data be prepared in a target-group-oriented, innovative and interactive way? ” was chosen as the winner by the interdisciplinary jury of the City of Leipzig taking into account clearly defined evaluation criteria. The city of Leipzig focuses on the usability of environmental data by citizens.

Convincing solution for the digitization of NO2 measurements

Hawa Dawa wins Munich Innovation Competition

Hawa Dawa was able to convince the cross-divisional and cross-departmental jury team of the Bavarian capital yesterday with its solution based on a network of cost-effective IoT sensors. The core of the challenge has been to provide measurement data for the recording of NO2 concentrations that are legally reliable and comply with the legal requirements and provisions of the 39th BImSchV, directly retrievable and of different periods (annual, daily and hourly average values) and that cover the city of Munich as extensively as possible.

Use existing urban infrastructures to measure air quality: “Smart Poles” of Westenergie and Hawa Dawa devices intelligently combined

Hawa Dawa is working with Westenergie AG’s Smart Pole Factory. In a project of the company in Essen, Hawa Dawa Sentience air measuring devices are installed in smart pole lights.

In a smart city, information on air quality can provide citizens with real value and, for example, help to improve the city’s transport planning. The Hawa Dawa air measuring devices are now being used in a pilot project of Westenergie. Together with the city of Essen and the Essen era supply and transport company mbH (EVV), Westenergie is testing intelligent street lights here. The so-called smart poles are equipped with sensors that also detect the parking space, for example. In addition to particulate matter, ozone and nitrogen, the Hawa Dawa Sentience devices also collect environmental data. The air quality data is transmitted to the Westenergie platform, which prepares this data for the municipalities and provides a clear presentation on the dashboard. On the six digital screens attached to the smart poles, information on local air quality can also be displayed directly to citizens.

Karim Tarraf, Managing Director of Hawa Dawa, explains: “We know from our discussions with municipalities that the Smart City initiatives are designed to make the urban environment more livable in an efficient way. Hawa Dawa solutions start right here: they can be used in both existing and new structures to digitally display air quality information efficiently and comprehensively. The cooperation with Westenergie in Essen shows what this can look like in reality. Intelligent street lighting is an important infrastructure element of a smart city. Also, our devices are designed in such a way that urban LoRaWan or GSM is used for data transfer. In this way, the bundling of individual technologies into holistic solutions brings significant added value for cities and citizens and focuses on improving the quality of life. Solution ecosystems are the economic form of the future. We are open to presenting the data ourselves in our dashboard products or, as in the case of Essen, to make the data available via an interface (API) for further use.”

Hawa Dawa’s approach is, as far as possible and sufficient, to use existing infrastructure and air quality measurements to make relevant air quality information available. The display of air quality information, which is processed depending on the application, can be carried out on an intuitive dashboard or by direct integration into downstream systems – e.g. for environmentally sensitive traffic control. Where the existing data density is not sufficient for the application, the installation of Hawa Dawa Sentience IoT measuring instruments can cost-effectively add additional measuring points.

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.”

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

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

Cities at the Forefront of Air Quality: Interview with Karim Tarraf, CEO of Hawa Dawa

In the days of Covid-19, “air quality” is a topic in the media, too. Cities are often pioneers in pushing for improvements. Decisions must be made in complex social contexts and measures must be integrated into larger plans. Here’s an interview with Karim Tarraf, CEO of Hawa Dawa, in which he comments on the following topics:
  • How can the increasing importance of air quality data be explained?
  • Why are the available measurements and data usually insufficient?
  • What does cooperation with cities look like?
