The New London Plan
The New London Plan came into force on 2nd March 2021 following a lengthy consultation process.
The Plan provides a strategic framework for the London Boroughs and is intended to be developed over the next 20-25 years. It challenges design teams to meet low carbon, energy efficiency and sustainability standards to assist the London ambition to be a zero-carbon city by 2050. The Plan embraces simulation to demonstrate well thought through design and augments the requirements to carry out detailed energy assessments through the RIBA Stages and beyond handover and initial occupancy.
Our team have extensive experience supporting the ever increasingly complex modelling demands now required through the planning process on major London schemes. We can assist with the Design Stage modelling (D) as well as the Sustainable Infrastructure (SI) policies that must be addressed in all areas of the built environment.
Through the use CFD we can undertake external comfort assessments in public spaces and around tall buildings, taking into consideration temperature conditions around the building, wind direction and pollutant dispersion.
Our team of consultants are experts at sunlight and daylight assessments. We can provide sunlight and shading analysis to contribute towards creating a comfortable pedestrian environment in public spaces and take into consideration the effects from tall buildings.
Our experts can undertake thermal assessments against TM59 to determine the risk of overheating and complement our solar studies.
Greater London Authority Requirements
Use less energy and manage demand during operation
Exploit local energy resources and be energy efficient by connecting to district heating networks
Maximise opportunities for renewable energy by producing, storing and using renewable energy on-site
Monitor, verify and report on energy performance
Whole Life-Cycle Carbon Assessments
Whole Life-Cycle Carbon (WLC) emissions must be calculated and submitted to the Greater London Authority to comply with the London Plan Policy SI 2. WLC emissions consider both carbon emissions from construction and use of a building in addition to the operational carbon emissions and embodied carbon emissions associated with raw materials and their logistics, and any carbon emission benefits after the buildng's end of life.
Using the IESVE and our partner software, OneClickLCA, the IES Consulting team can undertake whole life-cycle costing assessments on your behalf for pre-application, stage 1 submission (RIBA stage 2/3) and post-construction (RIBA stage 6).
- Geometry design to determine energy efficient and low-carbon shape and form of the building and make best use of solar and lighting
- Robust energy modelling, accounting for regulated and unregulated energy
- Identify opportunities for using, storing and producing renewable energy where application and report on CO2 reduction
- HVAC analysis to determine best use of heat pumps, domestic hot water approach and heating/cooling and natural ventilation
- Recommend material choice to reduce carbon emissions
- Estimate operational energy use using CIBSE TM54 or SAP for detailed insights
- Compare post-construction results against emissions baseline
Our expert team can offer a wide variety of complimentry services to help you meet each GLA requirement including Part L Compliance and building energy analysis for daylighting, solar, renewables and CFD.
Be Seen
The London Plan SI2 added the 'Be Seen' element - a new requirement for all major developments to monitor and report on their operational energy bridging the performance gap. IES Consulting can provide assistance throughout the three stages of the 'Be Seen' level and the RIBA stages from the detailed design into the handover and in-use.
Planning
- Revise the Part L model to incorporate areas where the buildings energy is not detailed under Part L via a detailed enhanced system based energy model.
- Perform detailed simulation on your HVAC plant and controls, providing greater insight into your building's likely energy performance, providing necessary results for TM54 and NABERS analysis.
- Undertake TM54 anlaysis to obtain a more accurate and detailed prediction of your energy use to identify areas where your building is not performing as predicted, accounting for regulated and unregulated energy use.
- Undertake NABERS Design for Performance assessment for office buildings.
- Incorporate virtual energy sub-meters that reflect the metering configuration of the real building.
As-Built
- Provide an update of estimated performance indicators in greater detail
- Confirm metering configuration is correctly calibrated
- Report on gas, electricity, fuel, heating and cooling consumption or 'be seen' documentation
- Produce a draft DEC certificate and predict energy consumption based on CIBSE TM54 for 'be seen' documentation
- Provide relevant outputs for Reportable Units for NABERS assessments for 'be seen' documentation
- Report on energy storage and renewable energy where applicable
- Create a Digital Twin of your building as it moves into the operation stage
In-Use
- Using our iSCAN technology our team can continually monitor your building's operational efficiency over a five year period and identify any areas where it is not performing as it should and provide solutions for mitigation where necessary in the 'be seen' documentation
- Provide inputs for all Reportable Unites for the 'be seen' documentation
- Produce official DEC for the whole building or NABERS certification for office buildings
Examples of Our Work
IES Consulting performed NABERS analysis on this six-star Green Star status building in Australia.
IES Consulting were commissioned to investigate the potential for solar glare brought about by the proposed West End Green mixed use development in London.
IES Consulting performed CFD analysis to determine the infiltration through open doors of the hospital entrance.
IES Consulting were commissioned to undertake a thermal comfort study of the proposed development to ascertain the overheating risk against CIBSE TM59.
