Facilitating a BREEAM Excellent rating for prime London residential estate
About the project
IN2 was appointed by Mount Anvil to prepare the Energy & Sustainability and MEP strategy for Stage 1 to 2+ to support the transformation of Lots Road South. This BREEAM Excellent accredited site sits on the boundary between Royal Borough of Kensington and Chelsea (“RBKC”) and London Borough of Hammersmith and Fulham (“FaciliLBHF”).
The development contains 274 new homes, including 65 affordable extra care homes, 53 affordable general needs homes and 156 market homes (Use Class C3). The development also contains 2,038 m2 of non-residential floorspace including flexible commercial (Use Class E (a), (b), (g), education, art gallery space (Use of Class 1 a/b) and community space (Use Class F2).
IN2 was appointed to provide guidance and set the parameters on the Energy and Sustainability and MEP systems for Stage 1 and 2+. IN2 engineering contributed and provided a Net Zero Operational Carbon Strategy for the Block B extra care homes specifically, demonstrating compliance with RBKC specification requirements, UK regulatory requirements, and industry-leading net zero frameworks. By minimising energy consumption, eliminating fossil fuels onsite, and maximising renewable energy generation to support the applicant’s sustainability ambitions aligns with local, regional and national carbon reduction targets.
Non-residential spaces located on the ground floor of the proposed development were assessed against the BREEAM New Construction V6.1 scheme with the objective of achieving an ‘Excellent’ rating for the following:
- Community Centre
- Social Investment and Employment Space (SIES)
- Flexi Commercial
- Exhibition space
Both Energy & Sustainability and MEP teams worked closely and recommended suitable sustainable design solutions for the MEP services of the development in line with local and national policies. MEP design highlights include:
- A central ASHP plant providing heating and domestic hot water for all units.
- A central high-efficiency system located on the roof of the block A provides cooling to the private residential and the commercial areas via fan coil units.
- Due to high levels of air permeability and tightness, a mechanical means of ventilation is critical to provide fresh air, reduce condensation risk, reduce mould risk, etc. it was decided that an energy-efficient MVHR will be provided in all units.
- Energy-efficient lamps, such as LEDs, are to be provided to reduce running and maintenance costs.
- Water restrictors are installed to reduce the consumption of potable water for sanitary use with water efficient components and features.
- Smart meters shall be prioritised throughout. All consumption will be monitored, including total generation, renewables, electric vehicle charging, space heating, water, etc.
Furthermore, IN2 Engineering provided comprehensive guidance and prepared a series of sustainability and performance assessments to support project’s environmental, operational and regulatory objectives. This included a Circular Economy Assessment which evaluated opportunities to minimise waste, optimise material efficiency and promote reuse and recycling throughout the building’s lifecycle. An Energy Strategy assessment was also undertaken to analyse the building’s anticipated energy demand and to identify practical planning and regulatory requirements.
In addition, the IN2 Engineering caried out a Whole life Carbon (WLC) assessment to reduce the embodied carbon associated with the design and material choices, ensuring that decisions were not only energy and cost efficient but also truly sustainable across the building’s lifespan. IN2 also conducted a TM59 and a Part O overheating risk assessment to mitigate potential thermal comfort risks within the building under current and future climate conditions.
