Glazing + Microshade

The windows are triple glazed to improve insulation levels and are low-e (low e can refer to low energy or low emissivity) coated to reduce solar heat gains. The windows on the northern and western façades are also fitted with a Viridian’s Microshade mesh. Microshade is a passive and highly effective shading element integrated in between the glazing layers. It consists of microscopic lamellas which shade the direct sun progressively. The shading effect of the microscopic lamellas can be compared to that of exterior shades. Microshade comes in 3 different angles, the ones used in the Desert Rose are at an angle of 16 degrees but they are manufactured up to an angle of 40 degrees which further reduce solar heat gains but also natural lighting. In summer when the sun is high in the sky the energy from the sunlight can be reduced by upto 90%. The R value of the windows is approximately 1 where as a traditional single glazed aluminium window is around 0.15.

30mm IGU (Insulating Glass Units) consisting of:

• 4mm clear toughened glass + microshade (MS-A for the 3 special windows)
• 10mm of Argon
• 4mm Performatech PH12(30) clear coating
• 8mm of Argon
• 4mm toughened glass

Blinds

Team UOW has installed Luxaflex Duette shade blinds in the Desert Rose. These blinds a series of honeycomb like structures that trap air and reduce heat loss through the window. This system traps air in the pockets of the shade which creates insulation that in turn lowers the energy consumption of the house. This air pocket system provides an R-value of 0.61.

These blinds feature a, ‘ultraglide’ retraction system that is optimal for those with arthritis and mobility restrictions due to its simple click and walk away system. A selection of hard to reach blinds around the house are controlled electronically via a control panel giving control to those whose mobility restricts them from accessing the lever system that is used on more accessible blinds around the house.

The translucent blinds allow for privacy and thermal comfort whilst still allowing for natural light to enter the space.

Direction

To reduce solar heat gains where possible we have reduced windows on the southern, eastern and western faces (as positioned in Dubai). We have installed clerestory windows high in the living space facing south to allow light to penetrate deep within the home without significantly increasing the solar heat gains. All of the windows can be electronically automated and the high clearstory windows promote natural ventilation.

Frames

The window and door frames are made from recycled hardwood timber that was salvaged from local demolition sites in the Illawarra, de-nailed and milled, reducing the carbon footprint of the home.

Automation

The windows in the Desert Rose House can be opened and closed using the KNX building management system. This enables occupants to easily open or close windows in hard-to-reach places such as above the kitchen sink.
