Hydronic technologies are undergoing significant transformations in an attempt to revolutionise resource independence in buildings. On-site energy generation and waste regeneration are at the centre of this potential paradigm shift. This text initially discusses recent developments in hydronics systems regarding energy source, materiality, distribution and location in buildings, and plenum typology. Secondly, it evaluates emerging innovation in water-based radiation geared particularly toward zero net energy buildings. Lastly, the text presents current research in hydronic technology in which water heating and disinfection are fully integrated into a facade system through microoptics integration. This discussion contributes to the evaluation of incorporating microoptics into future building technologies in which water, waste, and energy are synergistically balanced. The integration of microoptics can fuel radical innovation leaps in this front enabling regenerative hydronics.

“…Here, we present a theoretical study of an innovative sustainable lab-on-a-wall system called solar optics-based active panel (SOAP), 25 which has dual functions of solar energy storage and photothermal disinfection of bacteria in greywater. Additionally, our SOAP can achieve the disinfection in a few minutes and can store the energy without any additional energy storage materials because the greywater is used as a thermal energy storage material.…”

Solar optics-based active panel for solar energy storage and disinfection of greywater

Smart city and innovative building strategies are becoming increasingly more necessary because advancing a sustainable building system is regarded as a promising solution to overcome the depleting water and energy. However, current sustainable building systems mainly focus on energy saving and miss a holistic integration of water regeneration and energy generation. Here, we present a theoretical study of a solar optics-based active panel (SOAP) that enables both solar energy storage and photothermal disinfection of greywater simultaneously. Solar collector efficiency of energy storage and disinfection rate of greywater have been investigated. Due to the light focusing by microlens, the solar collector efficiency is enhanced from 25% to 65%, compared to that without the microlens. The simulation of greywater sterilization shows that 100% disinfection can be accomplished by our SOAP for different types of bacteria including Escherichia coli. Numerical simulation reveals that our SOAP as a lab-on-a-wall system can resolve the water and energy problem in future sustainable building systems. Published by AIP Publishing. [http://dx

“…In nano/micro scale, the artificial cell membranes based on the biomimetics are also reported by chemically/physically incorporating stimuli-responsive materials as functional gates into traditional porous membranes. However, a large-scale smart membrane with adaptive capabilities remains highly challenging1819. Since the fabrication of the current smart membrane structure is mostly based on incorporation or co-synthesis method which leads to less-controllable process20, irregular size of pores, lack of pore orderness, unclear open/close ratio of pores, stable actuation overtime, and mechanical stability of smart membranes remain as obstacles.…”

Smart membranes, which can selectively control the transfer of light, air, humidity and temperature, are important to achieve indoor climate regulation. Even though reversible self-actuation of smart membranes is desirable in large-scale, reversible self-regulation remains challenging. Specifically, reversible 100% opening/closing of pore actuation showing accurate responsiveness, reproducibility and structural flexibility, including uniform structure assembly, is currently very difficult. Here, we report a reversible, thermo-responsive self-activated pore membrane that achieves opening and closing of pores. The reversible, self-actuated thermo-responsive pore membrane was fabricated with hybrid materials of poly (N-isopropylacrylamide), (PNIPAM) within polytetrafluoroethylene (PTFE) to form a multi-dimensional pore array. Using Multiphysics simulation of heat transfer and structural mechanics based on finite element analysis, we demonstrated that pore opening and closing dynamics can be self-activated at environmentally relevant temperatures. Temperature cycle characterizations of the pore structure revealed 100% opening ratio at T = 40 °C and 0% opening ratio at T = 20 °C. The flexibility of the membrane showed an accurate temperature-responsive function at a maximum bending angle of 45°. Addressing the importance of self-regulation, this reversible self-actuated thermo-responsive pore membrane will advance the development of future large-scale smart membranes needed for sustainable indoor climate control.
