Carryduff MEP 600

Architects Paul Davis + Partners working with PHA Consult have won the Royal Society of Ulster Architects competition for 70 social and affordable houses to Code level 5 of the Code for Sustainable Homes at Carryduff, Northern Ireland.  The competition attracted submissions from 61 practices from the UK, the RoI and mainland Europe.

The judging panel unanimously agreed the design submitted by PHA Consult and Paul Davis +Partners to be the winning entry. The Chairman’s report referred to the strong presentation by PHA Consult’s Tomas Selva.

Part of the focus of the Environmental Design involved using thermal modelling to optimise the orientation and sunspace specification of each of the homes.

The challenging natural contours of the landscape required careful planning to manage surface water runoff. Community tanks harvest rainwater collected from the roofs, which then supplied the water to each of the homes down the hill and avoid the need for energy intensive pumping. These strategies allowed the community to meet the stringent Code Level 5 water efficiency requirements whilst reducing costs.

A comparison of community heating schemes such as ground source and air to water heat pumps, as well as biomass and CHP followed; and attention was drawn to their relative advantages compared to single home integrated solutions.

The findings were used to assemble an integrated system using solar hot water and drainage heat recovery to maximise the efficiency of a heat exchanger connected to a single unit air to water heat pump concealed in the rear garden. Well positioned roof mounted PV panels provided renewable electrical energy to power a full house ventilation heat recovery unit. The system was designed to, in future, offer occupants the opportunity of grid independent zero carbon living.

The project was designed by Foster + Partners, working with construction firm, CRIBA S.A. and local architect, BBRCH-Minond. Plans for the energy-efficient building, which will occupy an entire city block in the neighbourhood of Parque Patricios, echo its park-side setting with landscaped courtyards and shaded walkways and will provide a distinctive new presence for the bank in the city.

The scheme occupies the whole site to create an internal campus of ‘villages’, which are connected by circulation routes and external landscaped patios and are unified by a flowing roof canopy. The entrance plaza is sheltered by the deep overhang of the roof, which is supported by slender pillars. A full-height atrium directs circulation into four tiers of terraced office spaces, all of which have direct views of the park. Based on an eight-metre-square planning grid, the generous light-filled floor plates allow the work spaces to be flexibly planned.

The plans form part of a wider regeneration initiative in the barrio of Parque Patricios, a formerly light industrial area to the south of the city centre, which has been identified by the city’s government as a centre of technology. The design incorporates a number of sustainable features and targets LEED Silver accreditation. These include utilising the exposed thermal mass of concrete soffits with chilled beams for cooling; and reducing energy demands through shaded facades, which are oriented according to the path of the sun, and by encouraging natural ventilation.

PHA Consult are now working with local MEP engineering and LEED consultants GF/estudioGrinberg to develop the competition concept, providing advanced energy and systems modelling to ASHRAE 90.1,  natural ventilation simulation, and daylight and glare analysis.

Incheon Free Economic Zone Masterplan – Competition Win

Filed under: Uncategorized — Tags: , , , — egarrod @ 4:59 pm

Foster + Partners, together with PHA Consullt and Mobility in Chain, has won an international competition to design the masterplan for the expansion of the Incheon Free Economic Zone, an extensive mixed-use scheme encompassing the islands of KangHwa and OnJin-gun, to the north west of Seoul. Conceived as a self-sufficient, sustainable development, the 300 square-kilometre masterplan will extend organically from a central transportation spine, creating a centre for green industry and serving a population that is expected to grow from 35,000 to 320,000 residents and commuters.

The scheme integrates a range of low to high-density mixed-use areas, connected by a Light Rapid Transit system and construction will be phased over 10 to 15 years. The area spans three main sites within the free trade zone – the north of KangHwa will be a centre of inter-Korean economic cooperation, taking advantage of its strategic location close to Incheon airport and North Korea, while the south of the island will be mixed-use, combining green technology industry with community, cultural and residential buildings.

It is envisaged that Incheon will become a national centre for sustainable industry: manufacturing photovoltaic panels and wind turbines, and developing new products and technology within a new research and development institute in the south of KangHwa. State-of-the-art measures employed within the masterplan include biomass energy generation, the use of hydrogen fuel cells and hydroponic roofs. OnJin-gun island will be transformed as a sustainable resort and the wider IFEZ masterplan will eventually connect South to North Korea and the airport via the world’s longest bridge.

Taking agriculture as a central theme, the design utilises existing elements such as irrigation channels, green spaces and roads, while the arrangement of buildings within the masterplan follows the natural topology of the site, incorporating green roofs to further harmonise with the landscape. Like the veins of a leaf, the smaller roads and pedestrian avenues extend from the central transportation spine. The existing island is predominately agricultural so terraced farming, utilising the roofs of the industrial buildings, will replace any agriculture displaced by the development. There will be no structure above 50 metres, so the scheme will not extend into the foothills or mountain, thus preserving the rural landscape.
