A unique software tool, to help architects and specifiers accurately and quickly assess the impact of natural daylighting on a building’s energy performance, has been launched by Passivent. The company has worked closely with leading software house Environmental Design Solutions Ltd (EDSL) to develop the utility (Passivent Sunscoop Builder) which complements the already proven Passivent Airscoop Builder tool for natural ventilation in buildings.
Both tools are based on substantial, recently published research.
Available as a free download from the website, Passivent Sunscoop Builder enables users to model quickly the building daylight factor with Passivent’s ducted lighting systems – Sunscoops and Sunstracts. It also enables calculation of the number and size of Sunscoops and Sunstracts required to achieve a given internal illuminance, and their associated impact on energy and carbon performance.
Further, the Airscoop element of the tool has been upgraded for enhanced user interaction, and to encompass the latest additions to the product range.
The Passivent Sunscoop and Airscoop Builder has been purpose designed to interface with EDSL’s established Tas building thermal analysis tool.
