The Highest Performing Daylighting System

Why it is more advanced than a Skylight

Skylights have been around in various styles for many years now and most of us have experienced a skylight at some stage during our life, whether it was a traditional square skylight, a tubular skylight or a plain old roof window.

Often there can be array of issues associated with Skylights, this is where Solatube has come into a league of its own - developing a tubular daylighting system that overcomes these issues and set's to change the way we thing about natural daylighting.


Problem:
Solar Heat Gain

Traditionally because skylights filter sunlight into our homes there is an additional heat load placed on that room and generally the bigger the skylight or roof window the more heat is transferred. This not only makes your room more uncomfortable but also increases the need for air conditioning & other cooling measures. Especially during the warmer summer months when the sun is at its hottest.

WERS (The Australian Windows Energy Rating Scheme) & the NFRC (National Fenestration Rating Council) use a measurement called Solar Heat Gain Coefficient or SHGC for short, to judge a window or skylight products energy performance in terms of the amount of heat transferred into a room.
Unfortunately Skylights in New Zealand are not required to undergo the necessary testing to assess their SHGC performance. This means that as a consumer, it makes it difficult to compare New Zealand Skylight products effectiveness against heat gain.

Solution:
Solatube Daylighting System

Our Daylighting Systems incorporate a wide variety of technological advances, including advanced optical technology in the dome, a patented protective coating on the tubing & a duel lens system in the diffuser, to name a few. We are proud of these completely unique system features and have had both of our 160DS & 290DS daylighting systems tested by the NFRC.

Our results of an R-Value of .41 were so impressive, both our 160DS & 290DS Daylighting systems have been awarded the prestigious Energy Star label in the USA.

Be aware some manufactors will provide SHGC figures as some of the componants they use have been tested individually. But these results would not be true for the system as a whole once it is installed. Be sure to check that any SHGC figures provided are for the 'complete system' installed, as ours is, rather than just a few of the componants used.

Problem:
Heat Loss

By their very nature a Skylight needs to be installed through your roof & into the room below. During the cooler months, this offers rising heat an easy form of escape, making the area drafty and increasing energy required to heat the area. Again the NFRC has produced a measurement designed to provide a guideline for heat loss performance for all window & skylight products. This measurement is called a U-Factor and is judged in units of 2-10, the lower the better.

Again, sadly, New Zealand Skylights are not required to obtain tests in order to assess their U-Factor performance. This of course means that few New Zealand manufacturers have put their skylight products through these tests, making itdifficult for you to compare these products & ensure they won't impact on your homes energy efficiency.

Solution:
Solatube Daylighting System

Our Daylighting systems have been designed specifically as a completely sealed singular system with a variety of cutting edge techniques used to provide exceptional insulating results. Both our 160DS & 290DS Daylighting systems have again been tested by the NFRC and we are proud to announce that again our result of just 2.44 was very impressive, even compared to most double & even triple glassed windows available on the market!

Be aware some manufactors will provide U-Factor figures as some of the componants they use have been tested individually. But these results would not be true for the system as a whole once it is installed. Be sure to check that any U-Factor figures provided are for the 'complete system' installed, as ours is, rather than just a few of the components used.

Problem:
Installation

Again because of the way a Skylight works, they are very limited in where they can be placed within the home. Traditionally they can only be installed directly over the room they are to be installed in. The advent of Tubular Skylights, tube lights and sun tubes provided a little more flexibility with positioning. However they were still limited by obstacles in the roof and the tube length required to travel from the roof to the room. The longer the tube, the more light is lost.

Solution:
Solatube Daylighting System

Our Daylighting Systems use a unique and patented reflective tubing which allow our systems to travel over much greater distances, even around obstacles in the roof. In fact the 160DS can travel up to a huge 6m with limited light loss. The 290DS can travel even further, up to 9m with similar limited light loss results. How many Skylights can do that?

Problem:
The light can look "off colour"

Often, because of the quality of the dome, the tubing or even the diffuser, elements of the colour spectrum contained in natural light get lost in the transmission of the sunlight from the roof into your room. This causes the light to look yellowish, greyish or simply 'off colour'. This discolouration means items in your home won't look as intended. Coloured furniture and walls will look dull and lack the impact they once made.

Solution:
Solatube Daylighting System

The optical technology used in the dome and the reflective quality of our tubing means that our Daylighting Systems transmit 100% Colour Rendition, (with a 100% UV filter) into your home. This means you'll get exactly the same light inside as you see outside, which can truly transform the room. You can enjoy the colours in your home as they were always intended; bold, beautiful & natural. In fact our systems provide such quality results that they are the natural lighting product of choice for Architects and designers the world over.

Problem:
Lack of control

Ever considered having a skylight installed but then realised you had no way to turn it off? Many people also find it frustrating that skylights produce too much light and excess heat when the sun is at its highest point around midday.

Solution:
Solatube Daylighting System

Our Daylighting systems have been built with a variety of options available to you, the homeowner, in order to provide exactly the control you need.
- Our electric daylight dimmer, allows you to dim daylight from 100% down to just 2%, providing you with exactly the amount of light you want, no matter what time of day it is. 
- Our Designer Touches accessory range, allow you to choose the lighting effect you want depending on the ambiance or look you want to achieve.
- Our systems provide tested & measurable lighting outcomes. Which means we can provide a professional lighting design using daylighting solutions providing a consistant light output, regardless of the time of day or the weather outside, if that is required
