Efficiency, Energy & Net-Zero Carbon Audits

Longevity Partners’ audits support real estate asset value by boosting resource and energy efficiency, optimising CAPEX planning, and mitigating risks of obsolescence — all while ensuring alignment with credible decarbonisation pathways. Through detailed technical analysis and investment-grade retrofit planning, owners can future-proof their portfolios, avoid stranded asset risks, and boost attractiveness to sustainability and value creation-focused investors and tenants. This proactive approach supports long-term asset resilience, regulatory compliance, and value creation at exit.

Our Services

Asset-Level Audits

A comprehensive technical assessment for individual buildings, aligned with CRREM pathways, UKGBC Net Zero Carbon Buildings Standard, and ISO 50002.

• Full building walkthrough and system diagnostics
• Dynamic energy simulation
• Embodied carbon modelling for proposed upgrades
• Detailed list of Energy Conservation Measures (ECMs)
• Renewable energy feasibility (on-site + off-site PPAs)
• High-resolution CAPEX and ROI breakdowns
• Actionable pathway to net zero by 2040/2050

Portfolio-Level Strategy

Transformational decarbonisation planning across multiple assets, designed to integrate with fund-level sustainability objectives.

• Portfolio benchmarking and CRREM risk mapping

Your Outcomes

Reduced Operational Expenditure
Our audits uncover and prioritise energy-saving opportunities that deliver measurable cost reductions. By implementing targeted ECMs—such as lighting upgrades, HVAC optimisation, and AI-powered controls—owners can improve Net Operating Income (NOI) and reduce exposure to volatile energy prices.

Maximised Asset Value at Exit
Improved energy and carbon performance enhances an asset’s resilience, regulatory compliance, and appeal to sustainability and value creation-conscious buyers. Our audits:

• Extend asset viability under tightening carbon regulations (e.g., MEES, CRREM, SFDR)
• Help maintain or upgrade EPC ratings
• Support marketing narratives around green credentials
• Strengthen positioning for green financing and favourable exit valuations

Implementation-Ready CAPEX Roadmaps
We go beyond recommendations by providing investment-grade cost plans for each retrofit measure. Our approach includes:

• Realistic capital cost estimates based on market testing and recent tenders
• Full on-cost coverage (contractor prelims, inflation, risk, consultancy fees)
• Phased investment planning tied to lease cycles, grid decarbonisation, and equipment end-of-life

These detailed roadmaps empower asset managers to forecast, budget, and implement with confidence—turning climate goals into investable projects.
