A plain English explanation of this ACT planning and property term.
Solar building envelope is the three-dimensional space within which a building or structure must be contained to protect solar access to adjoining residential blocks.The solar building envelope is determined by applying the prescribed solar fence height and projecting a solar plane at the required angle from the solar fence. The envelope varies depending on factors including the block size category, development type, and the location of the adjoining residential boundary.
The solar building envelope is a 3D height limit that controls where a building can be placed and how high it can be to avoid unreasonable overshadowing of neighbouring residential properties. To assess compliance, you identify the relevant block type and development type, apply the required solar fence height and angle, and confirm that the proposed building fits within the imaginary solar envelope.
