solar panels efficiency comparison
Most skylights are now generally well-sealed and double glazing helps minimize condensation and heat flow through the skylight.
In Australia, the skylights are now rated by the Classification System of energy roof, and 5-Star Energy efficient skylights are available. The rating is calculated by the performance of your unit in winter and summer.
The WERS (Window Energy Rating System) for skylights provides an analysis of Energy rating and comparison. The plan takes into account the key differences between the energy performance of windows and skylights and how your home address to the different units.
What type of skylight is to bet on your home?
When choosing the skylights can select from a window Heaven, which opens for ventilation, or a skylight / ceiling light. Depending on the manufacturer of the skylight, they may have slightly different names.
The Windows of Heaven
Broken Windows are particularly suitable for rooms with a cathedral or sloped roof, but not the ceiling space. Having a window can be opened the sky is great for warm summer months, to release the heat that builds up on your roof.
Double glazing and selective use of low-e coatings reduce solar transmission. Using a sealed IGU (insulated glazing unit) allows the option of argon gas instead of air gap, which further reduces the heat transfer through the unit.
Skylights / ceiling lights
Dome skylights typically have long shafts and a diffuser panel fitted to the roof. Make sure the shaft walls are closed / lined and insulated so you do not act like a giant hole in the ceiling insulation.
Tubular Skylights reduce absolute heat loss and heat gain due to its small cross-sectional area. This lighting effect is based on the capacity of your drive for capture direct sunlight and diffuse beam to peak around the room.
They work best in your home if your climate has a high incidence of days clear and sunny. On cloudy days the amount of light admitted is considerably lower than for a large area, conventional skylights.
So what type of skylight is best suited for my local conditions? HomesTasmania Sunrise has identified four key elements to determine the skylight suitable for your location:
1. Do I live in a warm or cold?
2. The angle of the sun in the sky (different in Tasmania at Rockhampton)
3. The amount of covered versus sunny weather instead
4. Are there high levels of air pollution and haze?
Skylights can come with interior blinds or other types of sun protection or summer you can get the most out of your skylight over the year
