The current study provides an extensive review of the various solar energy techniques employed in achieving zero energy buildings (ZEBs). The study underscores the critical role of both passive and active solar energy techniques in reducing the energy demand of buildings and generating renewable energy to meet the remaining demand.
This study investigated the energy flexibility of a net-zero energy (NZE) house using a solar-assisted air conditioning system with integrated thermal energy storage (TES) and demand-side management (DSM) strategies.
The most used passive solar techniques to achieve zero energy buildings in recent works include orienting a building to take advantage of the sun’s natural heating and cooling effects, using large windows and skylights, shading devices, and thermal mass materials (Chan et al. 2010). Broadly, these have been categorized as passive solar gain.
Solar air heating as illustrated in Fig. 19 is a passive solar technique that is applied in zero-energy buildings. This technique uses solar energy to heat the air in a building, reducing the need for artificial heating (Ghritlahre et al. 2022).
Zero-energy buildings (ZEBs) are any building or facility characterized by their total energy consumption equal to zero for a given period and their carbon emissions equivalent to zero. This building typically uses less energy than traditional buildings . These types of buildings generate and then consume their energy.
