Sun Angles, U-Value, Radiation-Based Heat Transmittance and Temperature Transmittance, and Boundary Layer Flow are four specialized tools available on the Pinpoint platform, designed to optimize the building envelope during the early planning stages. These tools support architects, planners, and engineers in designing energy-efficient buildings by analyzing solar exposure, heat transfer, and airflow dynamics.
The Sun Angles Computation tool calculates the monthly variation and diurnal change of sun angles based on geographical latitude. It determines sun elevation in relation to azimuth and time of day, aiding in daylighting, shading strategies, and passive solar design.
The U-Value Computation tool calculates the heat transmission coefficient (U-value) by considering material properties, thickness, and heat transfer coefficients. It computes the resistance of each layer, the total thermal resistance of the construction, temperature profiles across layers, and the overall heat transmission efficiency, helping to assess thermal performance.
The Radiation-Based Heat Transmittance and Temperature Transmittance tool analyzes non-stationary thermal effects in both single and multi-layer constructions. It calculates temperature transmittance (TT) and radiation-based heat transfer, enabling precise evaluation of thermal comfort and energy efficiency in dynamic environments.
The Boundary Layer Flow tool determines the maximum allowable Ug-value for glazing, considering window height and external temperature. This ensures indoor thermal comfort by preventing the sensation of drafts caused by radiation deficits.
By integrating these computational tools into the design workflow, the Pinpoint platform provides essential data for optimizing building envelopes and ensuring sustainable and energy-efficient construction.
