Project Principals and Objectives:
In line with the London Plan Be Lean, Be Clean, Be Green hierarchy, the Phase 2 RMA proposals incorporate numerous passive and active design measures.
The proposals are oriented to optimise energy efficiency, such as by avoiding excessive openings on north and south openings. In addition, a more efficient building envelope has been achieved compared to Phase 1, largely through the use of high-performance wall and pipework insulation materials.
The combined effect of passive and active measures to increase building efficiency and reduce energy demand result in a reduction of carbon dioxide emissions by 10% below the baseline levels stipulated by Part L of the 2013 Building Regulations.
The Phase 2 RMA Proposals incorporate two CHP units, which aligns with London Plan Policy 5.9 and Local Plan Policy EQ1 encouraging the use of such measures. The effect of the two CHPs is to reduce carbon dioxide emissions by more than 25% below the 2013 Building Regulation baseline target.
Through the use of passive and active design techniques to reduce energy demand, plus the inclusion of two CHPs, the proposals will achieve carbon dioxide emissions in excess of 35% below the 2013 Building Regulations baseline.
The Phase 2 RMA proposals therefore align fully with the Energy Assessment approved under the hybrid permission and Policy 5.2 of the London Plan.
A mix of Private, shared ownership and affordable housing to be provided by this scheme which in turn require different specifications and design solutions.
The clients have a strong desire to exceed the requirements for sustainability and energy reduction laid out by building regulations.
As this is the second phase of the development, there are already residential dwellings in close proximity to the site and this required an understanding of site restrictions including access, air quality and health and safety.
