Value of Sustainability Calculator

Quantify the financial impact of sustainability interventions on commercial and residential assets.*

Asset & Intervention Details

Market cap rate pre-intervention. Used to calculate exit value uplift from cap rate compression.

Select Interventions

Value Driver & Protector Assumptions

Intervention Costs (USD/sqm)

Energy Savings (% total EUI reduction per intervention)

Conservative estimates based on whole-building EUI impact, not sub-system savings. Interventions may overlap; avoid double-counting if combining multiple.
Typical: 12–18% total EUI. Full replacement assumed.
Lighting ~8–10% of EUI; LED saves ~60–70% of that load.
Controls optimisation; HVAC must be functional to realise.
Primarily cooling load reduction in tropical climates.
Net offset; depends on roof area and orientation.
Behavioural/operational savings from audit process.

Value Drivers

Conservative end of 1.5–3% research range (Fuerst & McAllister; CoStar).
Applied as % of NOI. Conservative vs. 1–1.5pp observed range.
Mid-point of 10–15bps evidence (JLL, MSCI/IPD). Applied at exit only.

Value Protectors

Set by jurisdiction. Note: carbon value is typically a small contributor at current APAC price levels.
Actual 2023–24 grid emission factors. Jurisdiction-specific — select market above to auto-populate. Carbon savings appear small in dollar terms because APAC carbon prices remain low relative to energy savings.
NOI at risk of loss from regulatory or tenant obsolescence if intervention not made.
* Methodology draws on the Preserve framework, ULI climate change research, and a Value Drivers/Protectors framework. Benchmark coefficients sourced from GRESB, CBRE, JLL, and CoStar. Replace with portfolio-calibrated data for internal use. IRR is approximated via bisection; exit value uplift uses the income capitalisation delta formula (NOI × bps / (r × (r − bps))). Carbon savings are intentionally small at current APAC pricing levels — this is accurate, not a model error.
