Introducing Passivent Sunscoop™ Builder
WHAT IS IT?
Passivent Sunscoop Builder is a new unique software tool, to help architects and specifi ers accurately and quickly assess the impact of natural daylighting on a building’s thermal/energy performance. It has been developed by leading software house Environmental Design Solutions Ltd (EDSL) - which complements the already proven Passivent Airscoop Builder tool for natural ventilation of buildings.
WHAT IS TAS?
Tas is a building thermal analysis tool commonly used for calculating energy consumption and assessing peak summer temperatures. It is approved by the CLG for Part L calculations and for producing EPCs (energy performance certifi cates). The positive impact of Airscoops on room ventilation and of Sunscoops on the room daylight factor can easily be incorporated into these calculations. Tas has a long history of modeling naturally-ventilated and mixed- mode buildings to a high degree of accuracy.
WHAT DOES THE UTILITY DO?
Passivent Sunscoop & Airscoop Builder has been purpose designed to interface with EDSL’s established Tas building thermal analysis tool, which is the fi rst dynamic simulation modeling (DSM) of its kind to be approved for both Building Regulation Approved Document L2 and the Energy Performance Certifi cate. The Passivent programme adds a further dimension to the Tas Building Designer system, which already calculates performance taking into account the long-term dynamics affecting the building according to its location and orientation.
WHY USE IT?
Available as a free download from
www.passivent.com and
www.edsl.net, Passivent Sunscoop Builder enables users readily to model the building daylight factor to BRE methodology, taking account of Passivent’s Sun- scoops and Sunstract. It also enables calculation of the number and size of Sunscoops required to achieve a given internal illuminance, enabling their associated impact on energy and carbon performance to be assessed.
