Capital Renewal Forecast
Year-1 Operating Cost Composition
Asset-driven maintenance vs facility operations
Data Quality
How the asset list resolved against the reference library
Top Classes by Replacement Value
Replacement value (incl. risk premium) = qty × adjusted unit cost
Annual & Cumulative Renewal Expenditure
Scenario Comparison
Low / Central / High per ISO 15686-5 sensitivity treatment
Scenarios adjust unit cost (±15%), expected useful life (±20%) and the real discount
rate (0% / 3% / 5%) together (NIST Handbook 135).
Annual Renewal Totals, Year by Year
Every year of the horizon with its annual and cumulative renewal expenditure —
zero-spend years included
Renewal Summary by Asset Class
Each class renews on its expected useful life cycle; un-inflated current dollars;
risk premiums applied
Planned Renewal Spend by Year
Renewal Work Items
Click any cell to edit. Move items between years, set status and priority, and
replace model estimates with quotes or final costs — the plan-vs-model variance updates live.
Statuses: Planned (from forecast) → Approved (funded) → In
Progress → Complete (enter final cost). Deferred items stay visible but are excluded
from committed totals. Refresh from forecast re-syncs quantities and adds newly forecast renewals without
touching your edits.
Operating Cost Projection
Operating Guardrail
Year-1 operating total as % of construction cost
Default band 1.5%–3.5% of construction cost for institutional buildings; adjustable
in Inputs.
Breakdown by Category
Breakdown by Cost Logic / Delivery / Nature
Asset-Driven Maintenance (generated from your asset list)
Annual maintenance = replacement value × class maintenance % (APPA / NRC 2–4%
band, refined by system type)
Facility Operating Lines (area- and staffing-driven)
The annual operating budget to ringfence for running the facility —
cleaning, utilities, security, waste, grounds and management — over and above asset maintenance.
Auto-seeded from your floor area and building type using editable benchmark rates; click a row to
edit.
Lines marked Review are excluded from totals. Auto-seeded lines are generic
benchmark allowances — replace rates with quotes, contracts or client budgets as they are confirmed.
Maintenance: Actuals vs Projection
Track what maintenance actually costs each year against the model's projection —
live costs vs projected costs
Enter actual annual maintenance spend as years close out (campus-wide, all buildings).
Projection = asset-driven maintenance inflated at the model's inflation rate. Variance beyond ±15% is
flagged — persistent overruns usually mean the maintenance % or the asset list needs revisiting.
Uniformat II Coverage
Which building elements your asset list represents (ASTM E1557 rollup)
Groups at zero are not represented in your asset list. Renewal totals describe only
what the list contains — check absent groups against your project scope.

generic installed cost. Maintenance %: APPA / NRC 2–4% of replacement value, refined by system type. Risk
premiums: High +40% / Medium +25% / Low +10% (editable in Inputs). All defaults are starting assumptions,
not project pricing.

These values drive the guardrail, benchmark lines and projection
Data Management
Saving works through project files. Work lives in
memory while this page is open — download a .json project file to keep it (also the Save button
in the top bar). Restoring the file brings back every asset, edit, plan item and assumption exactly as
saved. An amber dot on the Save button means unsaved changes.
Buildings & Campus
One project can hold a whole campus. Buildings appear here automatically from the
asset list's Building column; add floor area or construction cost per building to sharpen scoped
results.
Use the Building selector in the top bar to scope every result view to one
building. Maintenance and renewal figures are exact per building; facility operating lines are pro-rated
by floor-area share (or replacement-value share when no per-building areas are set).

What is this?
The LCC Analyzer is a standalone life cycle costing tool. You give it three things:
1. An asset list — an Excel or CSV register of the equipment in your building (or type assets in manually).
2. Project basics — gross floor area, a construction cost estimate, completion year and building type.
3. Nothing else. Cost, service life and maintenance assumptions come from the built-in reference library of ~100 building system classes, every value of which you can override.
It returns a 30–60 year capital renewal forecast with NPV, an annual operating cost estimate (asset-driven maintenance plus area-driven facility services), scenario analysis, a guardrail check against construction cost, and a coverage report showing exactly what your asset list does and does not represent.
New in v3: the Renewal Planner turns that forecast into a live multi-year plan (statuses, priorities, quotes, year moves), one project can hold a whole campus of buildings, asset age times first renewals for existing facilities, and maintenance actuals track against projections.
Everything runs locally in your browser. No data is uploaded anywhere.

Getting your data in
- Create a project.
Name, building type, gross floor area, construction cost estimate, completion year. Floor area auto-seeds the facility operating lines; construction cost activates the guardrail.
- Import your asset list.
Any Excel or CSV layout works. The wizard detects your header row, lets you map columns (only Description is required), and shows a preview before anything is committed. A clean template is downloadable if you prefer to start from one.
- Let classification run.
Assets match to library classes by OmniClass/Uniformat code first, then by description keywords ("AHU", "air handler" and "rooftop unit" all find Air Handling Units). Whatever remains lands in a review list for manual assignment — individually or in bulk.
- Review and refine.
Check the dashboard, edit library values you have better data for, adjust facility lines, switch scenarios. Everything recalculates instantly and saves automatically.
- Export.
Project file (.json) for backup and sharing; CSV of the renewal forecast and class summaries for reports.
