LINARCH design






Compliance reporting is not as simple as it should be.

Even for something as simple as solar access and overshadowing, we find that many applicants have problems reporting the likely performance they have achieved.  The example shown on this page is typical. 

The original modelling was undertaken by a highly qualified ESD consultant, and alarmed the lawyers acting for the applicant because it suggested  serious shortfall from the compliance levels prescribed in the Residential Flat Design Code (which applied at the time). Our choice of modelling tool and the representation of the project by the 'views from the sun' technique made clear that winter solar access compliance was in fact so conservative that it could be characterized as best practice design.

The second example shown relates to natural ventilation compliance required by both the Residential Flat Design Code* and BASIX, the mandated sustainability rating in NSW. 

On this project, compliance with the deemed to satisfy solutions was going to be unlikely, so we relied on the performance objectives of the code.  We properly analysed the local climate data for cumulative frequency of cooling breezes in the summer months, and undertook some simple water-table modelling of likely ventilation patterns in the proposed apartments.  We were able to satisfy the approving authority that some single sided apartments were likely to achieve ventilation rates comparable to the cross ventilation simplistically defined in the  code.

*These days, the relevant code is the Apartment Design Guide
