SC6.6.5               Sustainable Building Design

(1)   Subtropical building design by its very nature is considered a sustainable building design approach given its principles as per
      section SC6.6.2. This policy provides further guidance to ensure that development within Noosa Shire:
      (a)    incorporates water sensitive urban design principles to manage stormwater;
      (b)    minimises the reliance on non­renewable resources;
      (c)    is designed and constructed to be energy and water efficient;
      (d)    includes operational initiatives for energy efficiency;
      (e)    collects and uses stormwater on site for non­potable purposes of gardening, toilet flushing, laundry and hot water supply
             uses; and
      (f)    provides healthy indoor environments by incorporating the use of low toxic materials, natural light and cross ventilation.

(2)   Energy Efficiency:
      (a)    To minimise energy consumption and the production of greenhouse gas emissions buildings incorporate:
             (i)      passive design measures to maximise the use of natural ventilation, cooling and natural light;
             (ii)     thermal mass, insulation and glazing for heating and cooling;
             (iii)    solar power or other non­polluting renewable energy sources to supply part or all of the development’s energy needs
                      (see Table SC6.6.1 for recommended size of Photo­voltaic system);
             (iv)     an energy efficient water heating system such as a solar hot water system or electric heat pump; and
             (v)      colours that reduce direct solar heat gain and achieve a maximum solar absorbance value or 0.5.

(3)   Water Efficiency and Stormwater:
      (a)    To maximise water efficiency on site development can incorporate rainwater collection and reuse measures for non­potable
             purposes such as irrigation (refer to Table SC6.6.2 for recommended requirements for land use activities).
      (b)    Development reduces stormwater run­off by minimising impervious areas and maximising site vegetation to absorb water
             on site through the application of water sensitive urban design measures to manage stormwater.
      (c)    Development limits changes and disturbances to the site topography to preserve existing drainage channels as much as
             possible.

(4)   Landscaping:
      (a)    Hard surface areas are minimised to reduce the reflection or storage of heat and maximise vegetation and soft
             landscaping.
      (b)    Vegetation is incorporated into the building design to create shade and cooling around buildings.

(5)   Design:
      (a)    Development and building siting is responsive to Noosa Shire’s sub­tropical climate and the site’s characteristics including
             topography, orientation, existing vegetation and prevailing winds.
      (b)    Buildings are designed to:
             (i)      make the most of prevailing winds, natural ventilation and cross breezes;
             (ii)     maximise shade to east and west facing walls;
             (iii)    incorporate wide eaves and awnings for shading;
             (iv)     contain an open and permeable built form that connects indoor and outdoor spaces in an integrated design;
             (v)      retain existing vegetation and natural shading where possible;
             (vi)     incorporate passive building design to reduce the need for auxiliary heating and cooling;
             (vii)    use low toxic internal and external building materials;
             (viii)   use natural light rather than artificial light, and may include skylights, atrium's and light wells;
             (ix)     contain a minimum of two openings per habitable room;
             (x)      provide a minimum floor to ceiling height of 2.7 metres; and
             (xi)     enable efficient operation and use of the building.

Editor's Note —The solar absorbance value is included in colour selection brochures provided by companies that supply roof materials. The National
Construction Code also provides some guidance on colours and their absorbance value.
