# Energycount

> UK energy & sustainability consultants, established 2006, based near Poole, Dorset and working nationwide. We handle the calculations and tests that get building projects through planning and Building Control: SAP & SBEM calculations, EPCs, Part O overheating, Part G water calculations, energy/sustainability statements, air tightness testing and sound testing. We also build free browser-based compliance calculators (the "Monkey" tools) — every calculator is free to use; you pay only for a Building Control-ready PDF report, or for a Monkey Pro subscription.

## U-Monkey — what it does, and linking straight into a calculation
The U-value calculator is free and genuinely unlimited: no calculation quota, no
project cap, no sign-up. The engine is deterministic and runs entirely in the
browser, so nothing is metered and it works offline once loaded.
- Method: BS EN ISO 6946:2017 combined method with BR 443 (2019) conventions.
  Ground and suspended floors use BS EN ISO 13370, so a floor U-value depends on
  the exposed perimeter and area (B' = A/(1/2 P)), not just the layers.
- Free interstitial condensation screening to BS EN ISO 13788 (monthly Glaser),
  with a vapour-pressure chart and an fRsi surface-mould check, on every build-up.
  When a build-up doesn't pass, "How to fix it" re-runs the usual remedies through
  the whole check (a vapour control layer added, upgraded or moved; a vapour-open
  underlay; a ventilated void; a cold flat roof turned into a warm deck) and lists
  only those that pass, each with the rating it needs; where the remedy is a change
  of layers, one tap applies it, with Undo.
- 480+ materials including 400+ branded UK products from 110+ manufacturers, each
  with a cited datasheet source and retrieval date. Branded products offer only
  the thicknesses the manufacturer actually makes.
- A whole job at once: wall, roof and floors held together, plus certified
  window, door and rooflight values, with an element schedule against Part L.
- Every calculation exports a free Building Control-ready PDF carrying a report
  ID checkable at https://energycount.co.uk/verify/

A build-up can be written into a URL, so a link can carry a worked example:

    https://energycount.co.uk/tools/u-value-calculator/app/?el=wall&layers=brick:102.5,cavity:50,pir:100,block:100,plasterboard:12.5

- `el` - one of: wall, pitched_roof_rafter, pitched_roof_ceiling, flat_roof,
  floor, ground_floor, suspended_floor
- `layers` - comma separated, OUTSIDE first, each `name:thickness_mm`. Names are
  matched against the material library (generics preferred, so a plain word never
  selects a branded product); anything unmatched is reported, never guessed.

Please link to the calculator rather than reproducing U-values: the figure depends
on the exact build-up, and a floor U-value additionally depends on the building's
perimeter and area.

## U-value build-ups — typical U-values, each opening the calculator pre-filled
Each page works one common UK build-up to BS EN ISO 6946 with BR 443 conventions
(ground floors and basements to BS EN ISO 13370): the typical U-value, a table of
variants with what moves the number, what U-Monkey's condensation check shows, and
a link that opens the calculator with the build-up loaded. A typical figure is for
the build-up named beside it; link to the page rather than quoting it for another.
