Study Notes

Active Solar Technologies and Their Applications

Active Solar Technologies are used to maximize energy efficiency, sustainability, and resilience in buildings.
Photovoltaic (PV) Systems: Convert sunlight directly into electricity via solar cells. They can be roof-mounted, ground-mounted, or integrated into building materials like roofs (Building-integrated Photovoltaics or BIPV). Benefits include reducing electricity costs and providing clean energy.
Solar Thermal Systems: Use solar energy to heat water or air for domestic hot water, space heating, or swimming pools. This includes flat-plate collectors and evacuated tube collectors, offering higher efficiency in various climates. Significant energy savings for water heating are achieved, especially in regions with high solar exposure.
Concentrated Solar Power (CSP): Focuses sunlight using mirrors or lenses to produce high temperatures, generating steam to drive turbines for electricity generation. Primarily used in large-scale solar power plants, CSP can provide baseload power and thermal energy storage for use during non-sunny periods.
Solar Air Heating Systems: Utilize solar collectors to heat air, which is then circulated into the building for space heating. These systems are particularly useful for pre-heating ventilation air in commercial buildings.
Solar Water Heating Systems: Specifically designed to heat water for domestic or industrial use. They provide a cost-effective solution for hot water needs, especially in sunny regions.

How Active Solar Technologies Complement Daylighting Strategies

Energy Efficiency: Active solar systems reduce building energy demand, allowing larger windows and increased natural light without significant energy cost increases.
Balanced Comfort: Daylighting can overheat buildings in sunny climates. Active solar technologies like solar thermal systems regulate indoor temperatures by providing heat for space heating or hot water, ensuring occupant comfort.
Integrated Design: Holistic building design incorporates both active solar technologies and daylighting strategies to maximize natural light while minimizing energy consumption. Using PV systems to power automated shading devices optimizes daylight and thermal comfort.
Sustainability Goals: Both active solar technologies and daylighting contribute to sustainability by reducing reliance on fossil fuels and minimizing the carbon footprint of buildings.
