Parkmount Estate

Parkmount Estate

Client: Richard Partington Architects

Alwitra®, in conjunction with the Northern Ireland Housing Executive and developers, the Carvill Group, has completed the first residential project to incorporate one of the world's only power generating, photovoltaic single ply roofing system - EVALON®-Solar.

The Parkmount Estate, in Shore Road Belfast, consists of 58apartments, many of which fully comply with new DDA regulations with internal dimensions that suit manoeuvrability for the disabled in wheelchairs. Designed by Richard Partington Architects, the scheme has achieved BRE EcoHomes "Very Good" standards and much of the concept is centred around the integration of the alwitra® "Solar" photo voltaic single ply membrane system - ensuring its ability to deliver to maximum capacity.

A long thin strip of previously derelict land, the site itself is aligned on a north-south axis, 3.5km from the centre of Belfast. Along its eastern edge there is a continuous frontage to
the busy Shore Road. To the west the land rises very steeply forming a densely wooded

The roof, on which EVALON®'s-Solar membrane is installed, forms part of a distinguishing key feature of the project. The profile helps to unify the scheme so that each of the repeated blocks is seen as part of a considered "whole".

The strength and clarity of the roof form is enhanced further by the integration of the PV Solar membrane system. The buildings respond directly to the ‘solar logic' with the lowest roof at the southern end of the site ascending at a constant 5° angle towards the north and culminating in the nine-storey tower. The roofs provide optimal inclination and
orientation to the southern sky (within plus or minus 20° of due south).

An array of 59m2 of grid-connected EVALON®-Solar photovoltaic panels was designed into the roof specification. The estimated annual output of 2,200 kWh/year, uses amorphous silicon modules, factory-bonded to the EVALON® membrane single-ply roofing membrane and protected by a fully weatherproofed transparent polymer coating.

The EVALON®-Solar system, launched in the UK two years ago by sole UK suppliers, ICB, remains the only product of its kind on the market - combining power generating photovoltaic capabilities with the flexible, design freedom allowed by a high performance single ply membrane.

To complete the "system", alwitra® offers a wide portfolio of highly engineered products including fine quality flashings, edge trims, roof lights, perimeter drains and roof drains, standing seam details, a "green" membrane (chlorine and halogen free), a self adhesive membrane for cold applied situations and a highly advanced extensive and intensive green roofs system.

All installations are carried out by licensed, fully trained contractors. A range of guarantee packages are available for added long-term peace of mind.
