Abstract
This dataset presents the numerical analysis of the heat and moisture transport through a facade equipped with a living wall system designated for greywater treatment. While such greening systems provide many environmental benefits, they involve pumping large quantities of water onto the wall assembly, which can increase the risk of moisture in the wall as well as impaired energetic performance due to increased thermal conductivity with increased moisture content in the building materials. This dataset was acquired through numerical simulation using the coupling of two simulation tools, namely Envi-Met and Delphin. This coupling was used to include the complex role the plants play in shaping the near-wall environmental parameters in the hygrothermal simulations. Four different wall assemblies were investigated, each assembly was assessed twice: with and without the living wall. The presented data include the input and output parameters of the simulations, which were presented in the co-submitted article (Alsaad et al., 2022).

Summary
Civil and Structural Engineering Heat and moisture transport through a facade equipped with a living wall system designated for greywater treatment Tables Figures Comma-separated values (CSV) files Numerical simulations using Envi-Met (version 4.4) [2] and Delphin (version 6) [3]. Envi-Met was used to simulate the effect of vegetation on the local climatic parameters at the living wall. The effect of a living wall system designated for greywater treatment on the hygrothermal performance of the facade, Energy and Buildings 255 (2022) 111711. This dataset illustrates how different wall assemblies can have different reactions to facade greening systems. It signifies the impact of correct selection of building material and insulation strategies when planning to implement such systems. The methodology and dataset presented in this article allow other researchers and building physicists to conduct further simulations using diverse wall assemblies, geometries, and boundary conditions. The presented output data allow for further analysis of the impact of novel decentralized greywater treatment systems on the facade
