Supporting new ways of working: partnering with IPUT to deliver a sustainable city quarter in Dublin

As the way we work is changing, organisations are considering how to make offices relevant to the future needs of workers. IPUT, one of Ireland’s leading property funds and Dublin’s largest owner of offices, set a vision to create an inclusive, vibrant and sustainable district at Wilton Park – integrating commercial and community space.

Stretching from Baggot Street Bridge towards Leeson Street Bridge along the Grand Canal in the heart of the city, the development centres on a restored one-acre historic park, comprising a mixture of private office and commercial spaces including new cafés, restaurants and retail facilities around a new public square.

Sustainability is the driving force behind this new development, designed as a resilient, adaptable space that enhances user experience. Arup has brought together a team of sustainability consultants, façade designers, civil, structural, mechanical and electrical engineers to design the four new buildings at Wilton Park.

One Wilton Park: a highly sustainable building

Working closely with architects Henry J Lyons, our engineers optimised the energy performance and carbon footprint of the building.

Renewable energy solutions include roof-mounted photovoltaic panels, co-ordinated into the roof plant compound’s cladding system. A combined heat and power (CHP) solution enables simultaneous generation of heat and electricity.

Our structural engineers ensured waste reduction and speed of construction by designing the precast concrete core walls with exceptional detailing.

This allowed exposure of finished structure within the building, reducing the amount of materials required and providing an enduring quality finish.

Incorporating sustainable design principles and digital solutions to ensure the highest standards of energy efficiency, the new development is targeting LEED Platinum, WiredScore Platinum and a Building Energy Rating (BER) of A3.

Natural daylight penetration has been maximised through carefully modelled lightwells and atria. Artificial lighting utilises high-efficiency, low power LED with automatic daylight dimming control.

Great places thrive on good foundations, so we are focusing on sustainability within our building design while bringing design thinking to the spaces and places in between. ” Niall Gaffney Chief Executive, IPUT

Building envelope design ensures user comfort

Occupant comfort, in terms of natural daylight and management of solar heat gain, was a key brief element considered in the overall design. Our façade designers developed a refined glass fin bracket solution and glass fin shape, using Sefar copper mesh and ‘shadow box’ double glazed opaque panels for enhanced shading and to control solar gains.

The most significant aspect of the overall building envelope is a seven-storey tensioned cable glass wall. This unusual aesthetic required highly technical specialist expertise, achieving the architectural intent of ‘no visible brackets’.

Our façade design derived the optimal balance between comfort, natural daylight penetration, energy performance and quality by using triple silver solar coated vision glazing in conjunction with 961 striking vertical glass fins and a bespoke unitised curtain wall façade with 7.5m long ‘strongback’ panels. These panels accommodated the design of the hanging glass fins positioned on the exterior of the wall and expedited their installation by enabling access from inside the building.

Wilton Park is being designed to create a new destination in Dublin – balancing flexible design with a striking aesthetic and high-quality build. We are working closely with IPUT and members of the design team to deliver a development that reinvigorates this beautiful part of the city. ” Picture of Adrian Ryan, Associate at Arup Adrian Ryan Associate Director

Recalibrating modern office culture

Inspired by IPUT and Arup’s Making Place report exploring the recalibration of modern office culture and its place in the wider urban context, the design team is bringing the findings to life to create a new landmark in Dublin’s central business district.

Future-proofing our design was key, ensuring that the buildings will have a long life. The structural scheme incorporates clear spans up to 16m on office floors, enabling flexible use of the space below.

High-quality digital workflows and building models were central to our design process and are a valuable asset to support excellence in operation.

Wellness and user experience were key design considerations. The development has been designed in alignment with WELL Building Standard (WELL), which marries best practices in design and construction with evidence-based scientific research and is the premier building standard to focus on enhancing health and wellbeing. One Wilton is the first building in Ireland to be awarded WELL Core v1 Precertification by the International WELL Building Institute (IWBI). The design of Two-Four Wilton is aligned to WELL Core v2.

Construction was completed on the 13,900m2 One Wilton Park in 2022, with the 41,800m2 Two, Three and Four Wilton Park due for completion on a phased basis between 2023 and 2024.
