Evaluation procedure
Appraisal 13.3.1
by adopting appropriate climate-responsive building design with the limited wwr and/or Srr as
mentioned above, and ensuring that all the fenestrations meet the ShgC requirement of eCbC-
2007, as per clauses 13.2.1–13.2.5. (2 points – mandatory)
Required documentation
1) Site plan showing north point, all building plans with internal layout showing the functional
spaces and interior layout, four side elevations, building sections and fenestration details.
2) details of sun path analysis for each exposed fenestration or use of shading norms to
demonstrate the use of optimum shading devices.
3) detail window and skylight schedule of the proposed building.
4) Submit the detail calculation in the prescribed format for wwr and/or format for Srr; to
demonstrate the percentage of vertical fenestration on gross wall area and/or percentage
of horizontal fenestration on gross roof area.
