Solar Radiation

This simulation evaluates cumulative solar energy received across the site during selected months and time intervals, quantifying spatial variations in exposure expressed in kWh/m². Using Radiance-based sky matrix calculations with Tregenza sky subdivision (145 discrete sky patches), the model integrates direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI) from climate files. Advanced ray-tracing algorithms process radiation values through geometric shadow analysis, accounting for sun position, building massing, vegetation, and urban morphology to determine precise energy receipt at each location.

Temporal filtering capabilities enable the analysis to capture seasonal and diurnal radiation patterns, revealing variations not visible in annual averages alone. This allows designers to understand both peak exposure periods and long-term solar accumulation across different site zones, providing essential insight into how architectural configuration affects solar resource availability.

The simulation supports evidence-based decisions regarding photovoltaic panel placement, solar thermal collector orientation, passive solar design integration, heat mitigation strategies, material selection, and vegetation planning. For sites with significant shading, this analysis proves critical for optimizing renewable energy deployment, validating generation assumptions used in sustainability certifications, and establishing foundational data for climate-responsive design where solar performance is integrated with thermal comfort, energy efficiency, and urban livability objectives.

Solar Radiation FAQ

What does the solar radiation simulation measure?

It quantifies cumulative solar energy received at each point in kWh per square meter, integrating both direct and diffuse irradiance from climate files through Radiance-based sky matrix calculations.

How can solar radiation data support renewable energy planning?

The simulation identifies optimal locations for photovoltaic panels and solar thermal collectors by mapping energy receipt across surfaces, validating generation assumptions for sustainability certifications.

What is the difference between solar radiation and direct sun hours?

Direct sun hours count time in sunlight, while solar radiation measures actual energy received in kWh/m2, including diffuse sky radiation. Solar radiation is essential for energy calculations and PV planning.
