  4. Abstract:
  5. This paper introduces an innovative approach that combines Net Zero Energy (NZE), Net Zero Carbon (NZC), and Regenerative principles, redefining sustainable architecture in Iran. Focusing on a residential “attached house,” the study employed strategies like thermal insulation, Low-E glass, shading, and renewable energy sources. Results show a 45 % improvement in thermal performance, reducing heating gas usage by over 42 % and electricity usage by 8 %. With shading, heating and cooling demands decreased by 51.7 % and 12.55 %, respectively. Swapping conventional walls for a thermal mass system led to a 74 % reduction in heating gas and a 17.2 % cut in cooling electricity. Additionally, PV systems supply up to 90 % of electricity needs. Environmental assessments revealed that the RM4 building achieved a 20 % reduction in environmental impacts, which increased to 65 % with PV systems and Solar Water heaters. All measures reduced the building's carbon offset by over 90 %, while greywater recycling and rainwater harvesting reduced water consumption emissions by 74 %. Using recycled materials, the Zero Carbon Buildings (ZCBs) model achieved a 68 % reduction in carbon emissions compared to the baseline and 27 % compared to the Zero Energy Building (ZEB) model, with a 67 % higher circularity. © 2024
