Nobu Hotel LondonMAIN BUILDING INFORMATION
A basic description of the project and building
The building is constructed from two structural systems, the lower ground sub‐structure is a mass concrete frame within a piled perimeter enclosure, and the upper floors are constructed from a post tensioned concrete slab. The post tensioning system is a low impact methodology as it reduces the floor depth, its material content and its carbon footprint. The proposed building will comprise five above-ground storeys, containing the hotel bedrooms, reception and conference rooms, and a double basement which will house the restaurant, bar and staff areas.
BREEAM Target Rating and Score
The building is being assessed under the BREEAM Bespoke 2008 Scheme, with a “Excellent” rating predicted, and a targeted score of 70%.
The key innovative and low-impact design features of the building
The embodied energy represented by the retention of the building is a significant fact in its sustainable credentials. With this project, the existing building have been demolished and replace with a Michelin Star Restaurant and Hotel.
Innovative bespoke façade system comprising of High performance solar control coated double glazed units acoustic laminated Class and thin GRC board marked panels. Green roofing system incorporating RW attenuation.
Light sources have been chosen for their efficiency, and the use of electric light is very low in the building. The studios are wired with multiple circuits to allow a reduced level of lighting to be maintained for safety without having to incur the cost of operating the full lighting installation. The choice of external light sources was also carefully controlled since any light pollution would be inappropriate. Lighting is used to signal entrances and escape routes, and have been confined to downward directed fittings.
Good U-value and insulation, natural ventilation where appropriate, exposed thermal mass and air permeability well beyond that required by building will also help the hotel to record usage and hence reduce specific energy usages.
This is a building well served by bus and train routes, which are described prominently in the hotel lobby. The project also introduced space for members of the public to enjoy this unique Michelin experience.

The steps taken during the construction process to reduce environmental impacts, i.e. innovative construction management techniques
A list of any social or economically sustainable measures achieved/piloted.
A central, dedicated space was provided during construction for the storage of the building’s recyclable waste materials. Site waste material was segregated and skips were covered where appropriate. Site Clearance and tree felling was under taken out with the nesting season. Existing tree was protected during the construction works. A clean tidy site was maintained.
An economic impact assessment for the project estimated that the hotel will generate 130 FTE jobs, directly and indirectly during the construction phase and 90 FTE job, directly and indirectly on a permanent basis.
The main reception area of the building (The Bar and Lobby; 168 sq m) is designed to be open, accessible and welcoming to all, and holds of travel information displays. Tour guides of the site during the construction stage were conducted with local neighbours.
