Flagship product

You have a net zero target. What you do not have is a costed plan for every building.

Retrofit Intelligence™ prices the measures that would actually move each building: what they cost, what they save, how long they take to pay back. Then it ranks them into a capex plan you can put in front of a committee. It runs on the building data you already hold.

How this usually goes

There is no shortage of retrofit advice. The problem is that an engineer’s report on one building tells you nothing about the other 299, and none of it arrives in a format you can add up.

“The engineer’s audit says replace the boiler. It does not say what that does to our stranding year.”

Head of Sustainability, pan-European office fund

“Every measure gets costed in a different spreadsheet by a different consultant, so nothing is comparable across the portfolio.”

Asset Manager, residential portfolio

“We can defend the CO2 number or we can defend the CAPEX number. We cannot defend the two together in the same document.”

CFO, listed REIT

What waiting another year actually costs

Retrofit decisions get deferred because the business case looks thin. Usually it looks thin because the model only counts energy savings. The value the works protect never makes it into the calculation.

10-20%

Brown discount already visible in pricing on office and retail with weak energy performance. Buyers apply it whether or not you have measured your own stock.

JLL, 2023

15-25%

Projected rise by 2026 in the cost of HVAC, glazing and insulation, which is most of what a retrofit buys. A deferred project comes back more expensive.

Savills, 2023

3.2% → 10.9%

Retrofit IRR modelled on energy savings alone, then modelled again with avoided value loss included. Payback falls by roughly 75 percent.

How Retrofit Intelligence™ builds the plan

Four steps, run on the building data you already keep in Blue Auditor. You do not have to run a new data collection exercise or bring consultants in first.

Establish the baseline

We pull meter readings, EPC data and fabric attributes into a single record for the asset. If the metered data is thin, the model falls back on certificates and gets sharper as more meters come online.

Locate the gap

We plot the asset’s carbon intensity against the CRREM 1.5C pathway for its country and building type. That gives you the year it stops being aligned, and how far over the line it sits in kgCO2e per square metre.

Model the measures

The model runs every measure that makes sense for that building type, on its own and in combination: envelope, HVAC, controls, on-site generation, electrification. For each one you get projected demand, carbon intensity, capital cost, the change in running costs and a simple payback.

Rank and sequence

Measures get ranked by CO2 saved per euro and laid out across a multi-year capex plan. Each version tells you the new misalignment year, so you can see what buying an extra five years actually costs.

What lands on your desk

Measure-level economics

Each measure comes with its capital cost, annual saving, CO2 avoided and payback, using the same units on every asset you own.

Outcome. A boiler swap in Vienna and a facade upgrade in Lyon sit on the same screen, priced the same way.

Scenario comparison

Run a few budget envelopes side by side, say 2m, 5m and 10m euro, and see what each one does to portfolio carbon intensity and stranding.

Outcome. Take a spend decision to the board with the alternatives already priced.

CAPEX and OPEX roadmaps

Measures land on a timeline with spend per year, payback windows and cumulative CO2 reduction.

Outcome. The business plan gets a real number instead of a placeholder.

Stranding year before and after

Each scenario returns the revised CRREM misalignment year per asset and for the portfolio as a whole.

Outcome. Answer the investor question “what does this buy us” with a date.

Funding and subsidy flags

We check each measure against the national and EU funding schemes it might qualify for.

Outcome. Net capex comes down before the case goes to committee.

Measured verification

When the works finish, the same asset record compares what you actually saved against what the model promised, using meter data.

Outcome. You can show the saving happened instead of quoting the forecast for years.
