Abstract.
Selection of an appropriate process is, therefore, the key to obtaining high-quality ferrites.
The raw materials used were NiO, ZnO, Fe2O3 of analytical reagent grade with 1 wt% Bi2O3 as sintering additive, 2 wt% MnCO3 as extra dopant to raise Curie temperature, 0.5 wt% Polyvinyl alcohol (8 wt% aqueous solution) as binder, and 0.5 wt% Davon C (20 wt% aqueous solution) as dispersant.

Thermal insulation materials are used for exterior walls, low-E glass for the double glass windows, vertical vegetation is used in the western and southern elevation to improve the building’s thermal insulation performance.
After all, a very large proportion of carbon emission in fact happens in the building operation stage, when the occupants play the key role.
In general cases and in the case studied in this paper, the building users are basically not professionals at architecture or building engineering, so they are not supposed to understand sustainable architecture principles or sustainable building technologies.
