    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

Thorn has supplied the lighting for 2 Stockport Exchange, a new six-storey office building that has been constructed next to Stockport’s mainline railway station. Thorn’s Beta 2, Katona and Voyager luminaires were chosen for their ability to address the exacting design criteria and ensure a high quality lighting solution with low total cost of ownership for the Grade A office development.

The Stockport Exchange development will deliver 375,000 sq. ft. of office space and 28,000 sq. ft. of commercial floor space and is part of an ambitious regeneration programme that is transforming Stockport town centre. 2 Stockport Exchange is the second phase that follows on from 1 Stockport Exchange and provides 61,502 sq. ft. of Grade A office space with a BREAM excellent rating, comprising large open plan offices with floor plates of up to 11,400 sq. ft.

Thorn’s design team worked in close collaboration with KNG Building Services and after submission of various samples and on-site trial mock-ups, were able to devise a scheme that addressed the exacting criteria and achieve the energy efficiency rating of A and LG7 standard for office lighting. Beta 2 LED square, recessed panels illuminate the office spaces, providing low glare (UGR 19, <3 000 CD/m2 at 65 degrees) illumination and ensuring comfortable ambient light. A high efficacy of >100 lm/W also achieves significant energy savings when compared
to traditional light sources.

Thorn’s slim, square Katona E3D LED luminaires have been installed in the stairwells. The smooth aesthetic design of Katona helps to reduces dust and dirt accumulation, is easy to clean and lowers maintenance requirements. The E3D version provides 3 hours self/addressable test and comes with a Lithium ION Battery with 3 levels of protection. 

All floors within the building feature Voyager Fit self contained emergency recessed luminaires. Voyager Fit uses easy to adapt interchangeable lenses and offers the most flexible optimised illumination for escape, anti-panic and spot lighting. Voyager Fit has compact proportions and requires only 80 mm ceiling voids for unobtrusive installation which means buildings with limited space can also benefit from the very latest in emergency lighting technology.
