TechNote#001 INITIAL INVESTIGATION INTO THE IMPACT OF THE ENERGY EFFICIENCY REQUIREMENTS OF BUILDING CODES ON GLAZED ENCLOSURES

{Originally wrote as technical note around 2005} INTRODUCTION The following technical note indicates some of the constraints on design that need to be considered when modifying an existing dwelling, by increasing internal floor area by enclosing a roofed area with glazing. (eg. A verandah or porch). Such extensions are generally not intended to increase habitable […]

Example Canopy Design and Documentation: Carports, Verandahs and Pergolas

Typically our involvement with carports, verandahs and pergolas, or more generally canopies, is the supply of structural reports or certification. Both reports and certification involve structural calculations, the difference between the report and certification is that we don’t compile the calculations into a report. Certification is only really appropriate for simple common place structural forms. […]
