19-22 The Quadrant is a mid-20th century building located within the Central Richmond and Richmond Green Conservation Areas and is adjacent to 4 Little Green (grade II) and 23 The Quadrant (Building of Townscape Merit). The proposed works are for a new rear extension of the second and third floor. A better more spacious office entrance was created on Little Green, providing dedicated disabled car parking bay a dedicated facility. The internal layout of the office floors was re-planned to provide additional, attractive, naturally lit office accommodation with new sanitary accommodation, including fully compliant DDA lavatories.

Energy Efficiency (Lean) – The Energy Strategy for the development has been calculated to reduce the carbon emissions from the development by 38% compared to a Part L 2013 baseline. This reduction is achieved by following the London Plan Energy Hierarchy. An energy efficient design contributes 22% in terms of carbon emissions reductions. Key energy efficiency features include a compact development, with additional glazing added to contribute to improved levels of daylight and beneficial solar gains.

Renewable Energy (Green) – A high efficiency hybrid VRF (Variable Refrigerant Flow) heat pump system with heat recovery is provide for the space heating and cooling to the office areas. Such systems is able to re-distribute heat energy around the building. The development is also utilised renewable electricity generation in the form of solar photovoltaic panels. The solar array shall be located on the second floor and Third roof, this 3.72 kW system is generating emissions free electricity. The proposed renewable and low carbon energy systems contribute to a 20% reduction in the residual Lean carbon emissions.

BREEAM is the leading and most widely used environmental assessment method for buildings and sets the standard for best practice in sustainable design. This development has committed to achieving a BREEAM rating of Excellent, which demonstrates best practice performance within the top 10% of all new developments in terms of sustainability Key Performance Indicators.
