Appold Street Mixed Use High Rise Tower
This project consists of a new build 45 storey mixed use tower in the heart of London. The tower will house approximately 10,000m² of office space,a 392 bedroom dual hotel partly aimed at business users and 260m² of ground floor retail space. Elementa has been appointed as part of the client team due to our experience with the owner on other mixed use, hotel and commercial buildings. We are influencing and proposing design and specification decisions/briefings to maximize the buildings efficiency based on our knowledge of the area uses and client specifications.
The building is targeting a minimum BREEAM target of “excellent”. Design features include a shared condenser water loop to VRF water cooled internal condensers, floor by floor ventilation across offices and hotel, thermal dump for peak lopping of cooling, high thermal performance facades and combined heat and power. The new development will be replacing the existing 10 storey building but despite the larger scale will operate more efficiently per m² due to its performance design.
Our input has led to reductions in plant capacity and therefore plant area. Our independent early input which is ongoing has reduced the clients risk in a number of design and design development areas. This has ensured a robust set of MEP client employer’s requirements and design stage reports are complete to a high level of sustainability and performance based design.
We have displayed innovation by implementing design standards on performance based results rather than application of the ‘standards’. As a mixed use building we looked to minimize plant requirements by recognising the different operational characteristics of the building as well as opening up the clients design team to sharing services where possible. We helped the team develop a workable distribution strategy in conjunction with a thermal heat dump in the form of the large sprinkler tanks to allow peak lopping of the cooling requirement suggested by the progressive client.
