What to examine
Focus on shading, orientation and seasonal generation. Coordinate these with building geometry, use patterns and adjacent systems. An individual product does not determine the performance of the complete assembly.
Inputs and comparison
Record dimensions, material or equipment properties, climate assumptions and required operation. Compare options against the same objective; distinguish a product rating from performance in a specific building.
Details and implementation
Resolve interfaces, installation access and future maintenance before work starts. Check critical concealed areas before covering them. Replacing a component requires reviewing connected details.
For your project
The outcome should identify the selected option, reasons, drawing or diagram and acceptance criteria. Final parameters require calculation and an agreed design.
