Decarbonisation Due Diligence
Integrated decarbonisation and environmental due diligence for real estate assets — combining engineering, climate science, and financial modelling into a single investment-grade report
What this service does
Terra Instinct delivers holistic environmental due diligence and decarbonisation strategy reports at the asset level. We bring together site surveys, environmental and contamination risk assessment, decarbonisation design, financial modelling, and climate risk analysis in a single report – giving you a clear picture of environmental and regulatory risk, stranding risk, and the value-add available from green interventions.
What the report covers
Key Findings Dashboard
EPC ratings, ESG risk flags, power supply constraints, destranding strategy, and EV charging opportunities, all at a glance.
Decarbonisation of Heat
Existing system audit, heat pump sizing and design (ASHP), scope of works, and system integration plan.
Energy Generation
Rooftop solar PV feasibility, panel layout, generation modelling (P90), direct consumption vs. export analysis.
Electric Vehicle Charging
Excess solar utilisation strategy, rapid charger specification, revenue modelling, and scalable deployment plan.
Energy Efficiency
LED lighting upgrades, heating modernisation, energy monitoring infrastructure and sub-metering philosophy (GRESB-ready).
Financial & Costing Analysis
Full CapEx schedule (materials, labour, EV/BESS), IRR and NPV modelling, cumulative returns, tenant savings, and energy savings over a 30-year horizon.
Regulatory Review
Planning history, Environment Agency data, MEES compliance assessment, EPC trajectory to 2027/2030.
CRREM Pathways Assessment
Carbon intensity benchmarked against the 1.5°C CRREM pathway, stranding risk quantified, net zero alignment year projected.
Climate Risk Analysis
Physical climate hazard screening under TCFD/ISSB (RCP 2.6–8.5), covering drought, flood, storm, hail, and heat stress.
Environmental Risk Assessment
Contamination sources, receptor pathways, risk summary matrix.
Asbestos & Hazardous Materials
ACM register review, observed condition, and management actions prior to works.
Contamination & Ground Conditions
Site history, geology / hydrogeology / hydrology, source–pathway–receptor analysis.
Site Operations
Bulk and hazardous storage, waste streams, drainage, oil interceptors, trade effluent.
Sustainability Baseline
Scored against 10 sustainability criteria including biodiversity, EV charging, water efficiency, green certification, and GRESB reporting readiness.
Site Context & M&E Conditions
Existing heating, electrical, DHW, BMS and renewables inventory.
What You Get:
A report that tells you not just what the building is, but what it could be - with the numbers to back it up. Typical outputs include:
-
EPC uplift pathway (e.g. C/D → EPC B across all units)
-
Unlevered IRR on the decarbonisation strategy
-
CRREM alignment confirmation and stranding risk removal
-
Costed scenarios (e.g. heat pumps + solar only vs. with EV charging)
-
Tenant savings quantified and charted
-
Ready-to-use inputs for green financing applications
-
Environmental risk position (e.g. “acceptably low for current use; no further pre-acquisition investigation required”)
-
Asbestos / ACM status and management actions
-
Contamination & ground-risk summary (source–pathway–receptor)
-
Regulatory compliance position (Part 2A, Environment Agency, planning, MEES)
-
Flood & physical climate risk rating (TCFD-aligned)
-
Sustainability baseline score (GRESB-ready)
Outcome
Environmental due diligence and a decarbonisation strategy in a single investment-grade report — showing you what the building is, the risks it carries, what it could become, and what it is worth in transition scenarios.
