Let our specialist dedicated team guide you through complying with regulatory standards and maximising energy performance to make your project a success.For new-build developments, as most of the information is available electronically from the design team, Whitecode are able to carry out sustainability assessments across the country.For existing buildings, we will be able to carry out assessments for developments located within London and the surrounding areas.

Sub-Services Overview


    BREEAM is the world’s leading sustainability method for master planning projects, infrastructure and buildings. Its methodology allows buildings to be assessed in terms of design, construction and future proofing using a common framework and recognised scoring system.

  • BREEAM Accredited Professional (AP)

    At Whitecode, all of our BREEAM assessors are also BREEAM Accredited Professionals (AP). As BREEAM APs we provide expert advice on built environment sustainability, environmental design and environmental assessment. The role involves facilitating the team’s efforts to successfully schedule activities, set priorities and negotiate trade off required to meet the BREEAM rating.

  • Code For Sustainable Homes (CSH)

    Whitecode Consulting has vast experience in carrying out Code for Sustainable Homes assessments, from small scale developments consisting of seven bungalows to large scale high-rise developments consisting of 400+ apartments. We have carried out assessments located in Central London and outside of London.

  • Daylight and Sunlight Analysis

    Whitecode Consulting have carried out Daylight and Sunlight Analysis for multiple building uses, including schools, commercial buildings and residential units. Using Integrated Environmental Solutions Virtual Environment (IES VE) software we are able to carry out advanced or simple calculations, depending on the building type and what standards/regulations are to be used. Therefore, we are able to meet the Client’s needs and can provide accurate results relevant to the development being assessed.

  • Energy Strategies & Feasibility Studies

    Whitecode’s sustainability team provide pre-app, planning and early design stage advice for all types of new developments requiring energy and sustainability reports. We have experience in producing reports which show compliance with local and national planning policies, ensuring your project meets the sustainability objectives and gains planning permission.

  • SAP Assessments

    SAPs are required to prove compliance with Part L1A/L1B of the Building Regulations and an Energy Performance Certificate is a legal requirement when renting or selling a property.

  • SBEM Assessments & Energy Performance Certificates

    Non-residential buildings are required to comply with Part L2A/L2B of the Building Regulations. There are two methods in which this can be done, with the Simplified Building Energy Model (SBEM) or Dynamic Simulation Model (DSM), both allow the production of an Energy Performance Certificate (EPC) at completion.

  • Approved Document O (Part O) Summer Overheating & Thermal Comfort Analysis Reports

    Overheating in residential dwellings is becoming a serious concern which was first raised by its incorporation into the London Plan which requires detailed studies for all major developments by the Greater London Authority (GLA).Overheating assessment is from June 2022 a requirement of Approved Document O of the building regulations meaning all sites will require a detailed over heating study. This would include a dynamic simulation report for most apartment blocks nationwide and a simplified calculation method for housing.

  • Sustainability Assessments

    Here at Whitecode Consulting, we can provide Sustainability Assessments for a variety of projects, including residential, mixed use or non-residential. We work closely with the Design Team to ensure that all requirements are met.

    Our Sustainability Statements meet the policies relevant to the project being assessed.

  • Thermal Bridging / PSI Value Calculations

    Our sustainability team are qualified to complete bespoke psi value calculations using 3D modelling software, for thermal bridging junctions. We can also check for condensation risk.

  • Home Quality Mark (HQM)

    Home Quality Mark was created by the BRE as a replacement for the Code for Sustainable Homes. It provides a mechanism to assess residential dwellings and enables householders to determine running costs, health and wellbeing benefits and environmental footprint associated with living in the home.

  • Whole Life-cycle Carbon Assessment (WLC)

    Whole Life-Cycle Carbon (WLC) emissions are the carbon emissions resulting from the materials, construction and the use of a building over its entire life, including its demolition and disposal. A WLC assessment provides a true picture of a building’s carbon impact on the environment.

  • Circular Economy Report

    A Circular Economy is as one where materials are retained in use at their highest value for as long as possible and are then reused or recycled, leaving a minimum of residual waste.

  • LETI

    LETI is the London Energy Transformation Initiative, which a network of professionals who are working together to drive the zero carbon agenda.
