Build greener from the ground up
From embodied carbon in materials and site energy to subcontractor emissions and whole-life carbon assessments, Noissime gives construction teams the tools to measure and reduce carbon across every project.
An industry racing toward net-zero targets
Construction and buildings account for nearly 40% of energy-related emissions. Clients, regulators, and certification schemes are demanding whole-life carbon transparency.
Why carbon accounting is hard for construction
Embodied carbon hard to measure
Steel, concrete, timber, and other materials each have unique supply chains and emission intensities. Calculating embodied carbon at the bill-of-quantities level is complex and time-consuming.
Site energy varies by project
Temporary power, generators, and mobile plant create a dynamic emissions profile that changes weekly. Tracking site energy manually across multiple projects is unsustainable.
Subcontractor emissions lack visibility
Most project emissions come from subcontractors and specialist trades. Collecting this data without automation is a quarterly fire drill that delays reporting by weeks.
Lifecycle assessment complexity
Whole-life carbon assessments require modelling embodied carbon (modules A1-A5), operational energy (B6), and end-of-life (C1-C4). Most firms lack the systems to do this at scale.
How Noissime solves it
Material-specific emission factors
Access emission factors for steel, concrete, timber, insulation, and other materials. Map each line item in your bill of quantities to its specific embodied carbon intensity automatically.
Project-level site tracking
Track site energy, generator fuel, and transport emissions by project. Noissime consolidates data across sites and applies the correct DEFRA or EPA factors per activity type.
Subcontractor data collection
Send automated data requests to subcontractors via magic-link portals. AI validates and extracts emissions data from whatever format they provide, improving data quality over time.
Simplified whole-life carbon assessment
Generate RICS-aligned whole-life carbon assessments covering modules A-C. Noissime handles embodied carbon, operational energy, and end-of-life scenarios automatically.
Purpose-built for construction and property
ICE and EPD database integration
Access emission factors from the ICE database and Environmental Product Declarations. Map materials to the most specific, up-to-date factors available.
BREEAM and LEED carbon reporting
Generate carbon reports aligned with BREEAM Mat 01 and LEED v4.1 requirements. Export project-level summaries and evidence packs for certification submissions.
Material substitution modelling
Model the carbon impact of alternative materials and design choices. Compare steel vs timber, concrete mixes, and insulation options to optimise whole-life carbon.
Embodied carbon and lifecycle assessment for construction projects
Carbon accounting for construction goes beyond site energy. Embodied carbon in materials accounts for a significant and growing share of a building's total lifecycle emissions. Noissime gives construction teams the tools to measure, compare, and reduce embodied carbon from design through to demolition.
Modules A through C: complete lifecycle coverage
The RICS Whole Life Carbon Assessment methodology requires construction firms to account for emissions across the entire building lifecycle. Modules A1 to A3 cover raw material supply, transport, and manufacturing of construction products. Modules A4 and A5 cover transport to site and construction processes. Noissime's carbon accounting for construction platform automates these calculations by mapping your bill of quantities directly to ICE database and EPD emission factors.
Operational carbon in modules B1 to B7 covers in-use energy, maintenance, and refurbishment over the building's design life. End-of-life modules C1 to C4 cover demolition, transport, waste processing, and disposal. Noissime models each stage using project-specific parameters, giving your carbon accounting for construction the lifecycle depth that BREEAM, LEED, and planning authorities increasingly demand. The result is a complete embodied carbon assessment that supports both tender submissions and regulatory compliance.

Collect embodied carbon data from material suppliers and subcontractors
Construction supply chains involve dozens of material suppliers and specialist subcontractors per project. Collecting EPD data and emission figures manually is a quarterly fire drill. Noissime's automated outreach funnel makes carbon accounting for construction supply chains practical at scale.
Material suppliers and subcontractors, engaged automatically
Upload your supplier and subcontractor list and Noissime sends each party an automated invitation via magic link. Every supplier receives a free account tailored to their trade. A concrete supplier sees questions about cement content and mix design. A steel fabricator sees questions about production route and recycled content. A mechanical subcontractor sees questions about refrigerant types and site energy use. No supplier faces a daunting fifty-page form, which means higher response rates and better data quality for your carbon accounting for construction projects.
As suppliers respond, their embodied carbon data and site emission figures flow directly into your project calculations. Noissime's AI validates each submission against industry benchmarks and EPD databases, flagging outliers for review. Over time, your carbon accounting for construction shifts from generic ICE database factors to supplier-specific primary data. Automated reminders and cooperation scoring keep engagement high across every project, helping you demonstrate genuine embodied carbon reduction to clients and planning authorities.
Free supplier accounts
Every material supplier and subcontractor receives a free Noissime account with trade-specific fields.
Direct project integration
Validated supplier data feeds straight into your project-level embodied carbon calculations.
Free carbon reduction plans for construction projects
Every paid Noissime account includes AI-generated carbon reduction plans that tell you exactly what to reduce, prioritised by impact and cost-effectiveness. For construction, these plans address both embodied carbon in materials and operational emissions on site.
Material substitution opportunities
Your free carbon reduction plan identifies where alternative materials deliver the biggest embodied carbon savings. Compare low-carbon concrete mixes, timber frame versus steel, and recycled content options. Each recommendation in your carbon accounting for construction plan includes cost differentials and carbon savings per unit.
Site energy and plant efficiency
Generators, temporary power, and mobile plant are significant contributors to construction site emissions. Your carbon reduction plan ranks site-level actions such as generator right-sizing, electric plant adoption, and grid connections by tonnes saved and cost-effectiveness.
Design-stage optimisation
The greatest embodied carbon reductions happen before a single foundation is poured. Your carbon accounting for construction reduction plan highlights design choices that minimise whole-life carbon, from structural grid optimisation to facade material selection and building orientation.
Updated per project phase
Your carbon reduction plan updates as your carbon accounting for construction data matures through each RIBA stage. When supplier EPDs arrive, when design changes are made, or when site energy data replaces estimates, Noissime recalculates and reprioritises your embodied carbon reduction actions automatically.
