It is highly desirable to secure the net-zero targets by employing
sustainable building materials that can store and release their
energy depending on the weather. Conspicuously, windows can
play a pivotal role in controlling the energy used in the building by
reducing the use of energy-consuming areas that devour massive
energy for air conditioning or heater appliances. Presently, the
comfort performance of window materials is reaching its storage
and processing limit, causing a significant push to find smart
materials that can be used in the next generation of the built
environment. An innovative solution for sustainable glazing has
established an understanding of pH-temperature-transparency
modulation. This work uses hydroxypropyl cellulose and polyacrylic
acid-based hydrogel as a rational energy stimulus for double-glazed
windows, enriching a comfortable indoor daylight environment
without sacrificing aesthetic appeal. Hydrogel maintains thermal
comfort across various outdoor temperatures from 4 oC to 60 oC.
The developed hydrogel-filled prototype glazing’s indoor thermal
comfort performance and durability were analsyzed, where
hydrogel intermolecular gap and porosity play a pivotal role across
various pHs.
