Solar energy systems therefore have an important role to play. The way solar systems are used is different from what it used to be, however. Buildings are no longer designed to use just passive solar energy systems, such as windows and sunspaces; or active solar systems, such as solar water collectors.
The building integrated solar thermal collectors has the potential to become a major source of renewable energy as being efficient, economically viable, environmentally and ecology friendly, but still some drawbacks to deal with including high initial cost, low efficiency for building integrated systems, and unstable system performance due to weather effect.

For this purpose, after a section discussing the existing zero-energy definition frameworks and design strategies, the major solar technologies have been presented as passive solar building design, building integrated photovoltaic systems, and building solar thermal systems.
The PV devices should be integrated with the building in a way that seems to be a natural part of the building and, without it, a part of the building appears to be missing. It should be architecturally pleasing. The design should be eye-catching, and it should add pleasant esthetics to the building. It should be well-composed.
Insulation is a crucial factor to take into account when choosing building materials while using solar energy. High-quality insulating materials can aid in the retention of heat produced by solar panels, increasing the system's overall efficiency. Materials like cellulose, fiberglass, or spray foam insulation can be used to accomplish this.
Solar panels can be included into a building's design as a stand-alone element or as a component of the façade. They can thus serve both practical and aesthetic functions, enhancing the overall appeal of the building. The direction and shading of the structure must be taken into account when incorporating solar energy into a building design.
Two major building demands that could be effectively addressed by solar energy are electricity and heat. Although not the only solar electricity systems, the common systems are PV modules. Integrating PV modules with the building could lead to an efficient design generating electricity while also providing other benefits.
Photovoltaic (PV) panels, concentrated solar power (CSP), and passive solar design are a few examples of solar energy technologies that may be included into building design. In order to produce energy directly from sunshine, photovoltaic (PV) panels are included into the planning and construction of structures.
