“Design of a boat is optimized for sail-driven locomotion. Buildings should be able to sail using free energy of wind, air, sun and internal heat sources to temper the indoor environment”, Brendon Lewitt. Based on this viewpoint, EPS course outlines the fundamental knowledge in building physics in relation to a range of environmentally responsive building design principles and computational approaches for increased resiliency for human habitability with minimal reliance on mechanical systems.

A. 03. Wind Rose and Wind speed analysis
The Þgure shows the total radiation for the sky dome. The surface PV design should be normal to the maximum solar radiation point.From the calculation of components, the angle between the pv panel and y-axis is 41 degrees and between x-axis is 295 degrees.
Wind prevails almost throughout the year in Pittsburgh.Although the winds coming from the West and South-West have greater velocity, upto 5.37 m/s, “calm winds” are experienced throughout the year from all the directions.South-West is the predominant wind direction observed annually.

The butterßy shadow diagrams for spring and fall equinoxes are almost identical. This highlights the criticality of these two dates and how they clearly mark the change in seasons from winter to summer and vice versa.

The highest and lowest sun angles are observed around noon in the summer, and the early mornings and late evenings in the winters.
