WASTE heat produced by the Guinness brewery could be used to help power the new National Children's Hospital.
Planners are considering using heat produced from the brewing process to power heating systems at the €650m hospital to help reduce costs and the building's environmental impact.
A feasibility study will be carried out on whether excess heat produced from St James's Gate could be re-used, by pumping it to the hospital campus.
The National Paediatric Hospital Development Board has also urged planners to reduce development levies imposed to pay for essential services.
In a submission to An Bord Pleanala, the hospital said that the hospital would be a "community facility" and that there "may be opportunity" to reduce the amount payable, which should be "closely examined".
A 10-year planning permission has been sought for the facility on the St James's Hospital campus in Dublin, which will cater for almost 75,000 patients a year, as well as providing research facilities and accommodation for families.
Two satellite centres, at Tallaght and Blanchardstown hospitals, are also proposed. Each of which would provide care for almost 25,000 patients.
The proposal includes:
◊ A 473-bed National Children's Hospital, including 93 day-care beds, and 380 inpatient bedrooms, all of which are en suite.
◊ The building will be 118,113 square metres, rising to seven storeys at the central oval-shaped ward pavilion. There will be external terraces at the second and third floors an a roof garden on the fourth.
◊ A 53-bed family accommodation unit, totalling 4,354 square metres, has also been proposed.
◊ A Children's Research and Innovation Centre totalling 2,971 square metres across a site of 0.14 hectares.
◊ A construction compound at Davitt Road in Drimnagh. This will be used during building.
◊ A children's hospital satellite centre at the Adelaide & Meath Hospital at Tallaght Hospital. To be built on an open area south of the main hospital entrance, it will rise to three storeys, and be 4,466 square metres, servicing 25,900 patients per year.
• A children's hospital satellite centre at Connolly Hospital in Blanchardstown, totalling 5,093 square metres across a 1.25 ha site, rising to three storeys. It will also cater for 25,900 patients a year.
The application comes after An Bord Pleanala previously refused permission for the facility at the Mater Hospital site in Dublin.
The National Paediatric Hospital Development Board said the hospital was "arguably one of the most important public infrastructure projects to be brought forward in the last 50 years".
Some 3,000 jobs will be created once the hospital opens, with an additional 2,000 during construction and commissioning.
It has also warned that some homes near the facility may suffer what has been described as a "moderate" loss of daylight.
