Dataset

This dataset is based on a full-scale research performed on two adjacent apartment buildings in Amsterdam. 

One roof has a bitumen surface with a solar PV system, the other is a blue-green capillary irrigated solar roof with 

grey (shower-) water suppletion, with a constructed wetroof for grey water purification. 

In the research, the solar output of both roofs was measured and compared, including temperature, irradiation and humidity measurements.

 The dataset covers 5 months, June to October 2022, and includes only day data (hours with solar irradiation).


The dataset is being made public to act as supplementary data for publication(s) and the PhD thesis of Els van der Roest. 

Also, it might be used by other researchers.


This dataset is a result of the TKI project Urban Photosynthesis and is co-financed with PPS funding

from the Topconsortia for Knowledge & Innovation (TKI’s) of the Ministry of Economic Affairs and Climate. 


Abstract of the paper:

With an increasing demand for climate resiliency, water sensitivity, nature inclusiveness and energy efficiency in dense urban environments, the call for layered and multifunctional use of rooftops is rising. Vegetated roofs combined with Photo-Voltaic (PV) installations are an example of multifunctional and more effective use of available space, and well-irrigated systems could have an enhanced cooling effect. This research investigated a blue-green capillary irrigated solar roof with grey (shower-) water suppletion, with a constructed wetroof for grey water purification. Two full-scale commercial PV systems on twin rental apartment blocks in Amsterdam were analyzed, on a blue-green roof (BGR) versus a bitumen roof (BiR). The energy output, PV panel temperature, relative humidity and air temperature under the panels were monitored during 5 warmer months (June-October 2022). On average, a solar panel on the BGR is expected to produce 4.4% more energy than a solar panel on the BiR at similar irradiation. A clear difference in panel temperature on the roofs is only seen when the surface temperature of the roofs differs by at least 4.64°C. Otherwise, other factors such as wind or albedo have probably more influence on the PV panel temperature and thus on PV power output.
