AECB PHribbon – Daylight Factor Module

£130.00 + VAT

SKU: 11026

Description

AECB Daylight Factor is a simple but powerful tool that makes daylight assessment quick and easy. It is designed by Mark Siddall of LEAP.

Daylight Factor helps you:

1) Assess daylight uniformity, so that you can appreciate whether light will be evenly distributed within each room.
2) Determine the daylit area, so that rooms do not appear gloomy.
3) Calculate the daylight factor of a room, so that you can be confident rooms receive and appropriate level of daylight, without being over glazed and prone to excess solar gains.
4) Avoid excess heat loss, because even high performance windows lose 5 to 8 times more heat than a good wall.
5) Demonstrate compliance with the AECB Daylight Standard.

Using Daylight Factor

If you are not a PHPP user don’t worry, or if you’ve not built a PHPP model yet, you can complete a conventional assessment using Daylight Factor. However, if you have a PHPP model you can speed up your workflow by allowing PHribbon to do some of the work – saving time and effort.

License terms and conditions

Users may not redistribute the PHribbon spreadsheet, or repackage it free of charge or otherwise.
The software has been rigorously tested and great care has been taken to ensure there are no errors, however not every situation in which PHPP can be used can be foreseen, therefore checks for costs are still recommended. Any mistakes found will be corrected free of charge and all users updated. The user is responsible for checking the figures, especially in circumstances where they are critical. In extreme circumstances the maximum compensation will be a refund of the price paid for the software. By using this software you agree that no legal claim can be made against the AECB nor Tim Martel.
Costs provided are indicative only and are the best information available to the author. By their very nature they are variable according to location, supplier and quantity. They serve only as a starting point and can be updated at any time either for one project (i.e. changing the figure in the costs tab in the PHPP) or by changing the master table for all future projects in the PHribbon spreadsheet.
