Ahmad, J.I. (author)Drinking water distribution systems (DWDSs) are intended to supply hygienically safe and biostable water for human consumption. To supply aesthetically pleasant drinking water at the customers tap, water treatment and supply requires energy for production and distribution purposes (e.g. overall between 0.47 kWh/m<sup>3</sup> in the Netherlands)....doctoral thesis 2022

van der Hoek, J.P. (author), Ahmad, J.I. (author)Door te verwarmen en te koelen met drinkwater<br/>hoeven we minder aardgas te verstoken en kunnen we<br/>klimaatverandering beperken. Maar is dat drinkwater<br/>daarna nog wel goed voor onze gezondheid? Bij de TU<br/>Delft en Waternet zochten ze het uit.journal article 2022

Ahmad, J.I. (author), Giorgi, Sara (author), Zlatanovic, L. (author), Liu, G. (author), van der Hoek, J.P. (author)Drinking water distribution networks (DWDNs) have a huge potential for cold thermal energy recovery (TED). TED can provide cooling for buildings and spaces with high cooling requirements as an alternative for traditional cooling, reduce usage of electricity or fossil fuel, and thus TED helps reduce greenhouse gas (GHG) emissions. There is no...journal article 2021

Ahmad, J.I. (author), Dignum, Marco (author), Liu, G. (author), Medema, G.J. (author), van der Hoek, J.P. (author)Drinking water distribution systems (DWDSs) have been thoroughly studied, but the concept of thermal energy recovery from DWDSs is very new and has been conceptualized in the past few years. Cold recovery results in a temperature increase of the drinking water. Its effects on drinking water quality and biofilm development are unclear. Hence, we...journal article 2021

Zhou, X. (author), Ahmad, J.I. (author), van der Hoek, J.P. (author), Zhang, Kejia (author)Thermal energy recovery from drinking water has a high potential in the application of sustainable building and industrial cooling. However, drinking water and biofilm microbial qualities should be concerned because the elevated water temperature after cold recovery may influence the microbial activities in water and biofilm phases in drinking...journal article 2020

Ahmad, J.I. (author), Liu, G. (author), van der Wielen, Paul (author), Medema, G.J. (author), van der Hoek, J.P. (author)Drinking water distribution systems (DWDSs) are used to supply hygienically safe and biologically stable water for human consumption. The potential of thermal energy recovery from drinking water has been explored recently to provide cooling for buildings. Yet, the effects of increased water temperature induced by this “cold recovery” on the...journal article 2020

van der Hoek, J.P. (author), Mol, Stefan (author), Giorgi, Sara (author), Ahmad, J.I. (author), Liu, G. (author), Medema, G.J. (author)Greenhouse gas (GHG) emissions contribute to climate change. The public water utility of Amsterdam wants to operate climate neutrally in 2020 to reduce its GHG emissions. Energy recovery from the water cycle has a large potential to contribute to this goal: the recovered energy is an alternative for fossil fuel and thus contributes to the...journal article 2018
