Automatic system for continuous monitoring of indoor air quality and remote data transmission under SMART_RAD_EN Project

Abstract

In September 2016, the SMART-RAD-EN Project was launched, funded by the Competitiveness Operational Programme 2014-2020 of Romania, to be developed up to the year 2020. The ambitious overall objective is focus on to the concept of "smart city" in terms of intelligent integrated solutions, which it aims to achieve in international premiere, in order to improve public health by increasing indoor environmental quality and optimizing the energy efficiency of housing in five urban areas of Romania. In this study, the current status of the development of the prototype system for continuous monitoring and remote data transmission on radon levels and other household air pollutants (CO2, CO, VOCs and temperature, pressure and humidity sensors) is presented, as an important objective in the frame of the SMART_RAD_EN project. The prototype for intelligent monitoring system was assembled and now is involved in the testing process. Metrology and quality assurance of the prototype system will be carried out within accredited European laboratories and by consulting with the international scientific experts. Remote data transmitted will allow: (1) real time interactive visualization, of the impact of user behavior on indoor air quality; (2) information in case of exceeding threshold levels; (3) to produce estimates of future pollution as a result of the correlation with the meteorological parameters (temperature, pressure and humidity) and user activity. The system, metrological validated, will be implemented in 100 houses with high exposure to radon and other ambient pollutants from the main Romanian urban agllomerations

The applicability of decentralized ventilation equipment in radon mitigation from existing homes

“…After the preliminary radon measurements were conducted and the smart equipment for continuous radon monitoring has been installed [17], the mean radon value for indoor concentration has been established around 510 Bq/ m 3 . The measurements were realized in an established period of 4 months (01.12.2018 -30.03.2019).…”

Sampling method for long-term monitoring of indoor environmental quality in residential buildings

“…To reduce the effort and cost entailed by IEQ-related studies, we need to consider decisions about both data sampling strategies and sampling frequency [14]. Hui et al [15] used CO2 as a reference to evaluate existing and proposed sampling schemes for indoor pollutant concentration in terms of the necessary sampling time and sampling point density and the probable errors induced at certain confidence levels of the measurement.…”

Development of a Geogenic Radon Hazard Index—Concept, History, Experiences

“…Therefore, it has been increasingly the subject of regulation aimed to reduce radon exposure. For Europe, the key document is the EURATOM Basic Safety Standards (BSS; [2]; similar to the IAEA-BSS [3]) and much literature deals with the many aspects of environmental radon, as well as a number of international research projects, such as RADPAR [4,5], SMART_RAD_EN [6], Rn in Big Buildings [7], and Life-Respire [8]. Some research was initiated to directly support the development and implementation of regulation, while other projects are focused on complementary activities such as to deepen the understanding of Rn behavior in the environment, to develop tools to quantify Rn, from measurement to displaying its distribution in the environment, and to assess its radiological significance.…”
