St Paul’s Square Development totals 1,650,000 sq ft of mixed-use development, incorporating offices, retail, cafes/restaurants and 285 new homes in the city centre of Liverpool. Hannan Associates were appointed to provide the performance specification and monitoring for phase 2 of the development which comprises the construction of a 170,000 sq ft Grade A office building.
Phase 2, Building 5 has been designed specifically to minimise energy usage, associated carbon production and utilises its own infrastructure to obtain a minimum of 10% of the buildings energy requirements from an on site renewable source. This has been achieved via the use of ground water source heat pumps which provide the buildings heating and cooling requirements in addition to the incorporation of further energy saving features such as:-
- Enhanced building fabric ‘U’ Values.
- External solar shading.
- Solar control glazing.
- Heat recovery ventilation.
- Intelligent lighting controls systems.
- Building Management System.
- T5 Lighting Technology.
The building envelope and the building services installations have been designed specifically to comply with the Part L2a (2006 edition) of the Building Regulations. Building 5 achieves compliance with an anticipated 32% reduction in carbon production when compared to a building constructed to comply with the 2002 Building Regulations. This reduction in the production of carbon is the result of the enhanced building fabric and the high energy efficiency of the systems installed, which will also be reflected in the operating costs.
The building and associated services have been designed to achieve a BREEAM rating of ‘very good’.
