TECHNAL Delivers Sustainable Solution for Brighton Student Accommodation

For Fresh’s Pavilion Point student accommodation scheme, TECHNAL’s high performance glazing systems manufactured from low carbon recycled aluminium provided the solution to meet the project’s thermal, acoustic and sustainability goals.

Pavilion Point is a Purpose Built Student Accommodation (PBSA) development on London Road in the centre of Brighton in East Sussex, close to the University of Brighton’s main campus. Managed by student accommodation specialist Fresh, the building provides 232 student rooms, dedicated social and study areas, a gym, café, multimedia space and landscaped courtyard as well as retail units on the ground floor. The five storey development, designed by Corstorphine & Wright, targeted BREEAM Excellent standards as well as high levels of acoustic performance.

TECHNAL’s Elegance 52 ST curtain walling, Dualframe 75 Si Tilt Before Turn casement windows, Stormframe STII doors and C160S lift and slide doors were all specified for the Pavilion Point building. The systems are designed to integrate together seamlessly, making it easy to build multiple systems into a single project.

In addition to the TECHNAL products, the external façade features a clay brick slip system for the ground to third floors with a grey rainscreen cladding on the set-back fourth floor. The use of TECHNAL’s aluminium systems contributed to creating an A1 rated non-combustible façade, a client requirement given the increased focus on fire safety.

Jose Tweedie, Associate at Corstorphine & Wright explained: “Having worked with TECHNAL on previous projects, including other PBSA schemes, we approached the team in the early stages of the design. Being able to draw on the knowledge and experience of Dean Sherwood and the wider team streamlined the process by helping us understand what could be achieved.”

The TECHNAL systems used on the Pavilion Point development were manufactured using Hydro CIRCAL® 75R recycled aluminium, helping to reduce the carbon footprint of the building. Hydro CIRCAL® 75R contains at least 75% aluminium from post-consumer scrap and as a result has one of the smallest CO2 footprints worldwide with 2.3 kg of CO2 emissions per kilo of aluminium. This is 86% or 7 times less than the global average for primary extraction.

Jose added: “The embodied carbon of products and systems is a key issue in the industry and as a practice we are always looking to embrace products and innovations that can help make our clients buildings more sustainable. When Dean presented Hydro CIRCAL® 75R as an option at no additional cost, it was clearly a positive change with no drawback. This was very much in line with our vision for the project and aligned with our goal for BREEAM Excellent as well as the operational CO2 reductions we aimed to achieve through the use of a renewable combined heat and power (CHP) system.”

The versatile TECHNAL Elegance 52 ST curtain walling features prominently on the front corner areas to maximise the light in the common and circulation areas, as well as on the ground floor retail units and the ‘pod’ windows that project out from building on the first and third floors.

The PAS24:2012 and 2010 Equality Act compliant Stormframe STII doors were used for the student reception entrance as well as fire escape and other general entrance doors. The TECHNAL Confort C160S lift and slide door was specified in place of bi-folding doors for the openings onto the courtyard area. The key benefit of the Confort C160S is that the innovative sliding mechanism ensures the door is light and easy to operate, whilst giving much larger pane sizes and uninterrupted vision when closed compared to a bi-folding door.

To ensure high levels of natural light in the student rooms, the design features large floor to ceiling windows. The Dualframe 75 Si Tilt Before Turn (TBT) windows were installed above a fixed glazing panel to create this feature. The TBT windows were selected as the inward tilt opening provides suitable ventilation while ensuring safety of the residents. The turn mode, which is engaged using a key, makes cleaning and maintenance from within the building simple.

The aim of achieving BREEAM Excellent certification as well as the building’s location on a busy road meant that the door, window and curtain walling systems had to also meet a number of specific performance requirements, not least a high level of acoustic performance. This was a challenge due to the size of some of the panels included in the design. TECHNAL system allowed a 41dB sound reduction to be achieved while optimising the weight of the glazed units.

The specification also included some challenging thermal and air-tightness requirements, however the TECHNAL systems were more than able to achieve the performance criteria. For example, the Elegance 52 ST curtain walling is capable of surpassing the 1.4 W/m²K U-Value target, something that cannot be achieved with some other systems.

Dean Sherwood, Project Consultant at TECHNAL concluded: “The Pavilion Point scheme demonstrates the value of close collaboration and how the specification of energy efficient systems manufactured from recycled materials can help achieve reductions in both embodied and operational carbon emissions. We are delighted with the finished result and pleased to have contributed to delivering a building that provides high quality accommodation for the students of Brighton.”
