Shuiyifang Housing integrates photovoltaic generation, full electrification, and passive strategies to achieve near‑zero energy consumption and reduce operational costs, establishing a residential model with very low energy demand.
The Shuiyifang development in Xi’an, China, is conceived as a low-rise residential complex designed to operate with very low energy use and an almost negligible carbon footprint. The project combines distributed photovoltaic production, full electrification of energy uses, and intelligent management aimed at minimising demand. Each home includes a solar installation of around 10 kWp capable of generating approximately 11,000 kWh per year, enabling residents to meet cooking, heating, cooling, and other energy needs without relying on fossil fuels. This strategy significantly reduces operating costs and supports the achievement of an energy balance close to zero.
Construction decisions also contribute to efficiency. The courtyard-style layout promotes natural ventilation and passive comfort, while the shear wall structure enhances seismic stability without notably increasing energy demand. The implementation of same-floor drainage eliminates maintenance issues and avoids invasive interventions that could compromise the building’s performance. Overall, the project demonstrates how the combination of renewable generation, electrification, passive solutions, and intelligent control can strengthen residential models with very low consumption, aligned with the transition towards zero‑emission buildings.
