What the buildings are teaching us.
Short, opinionated essays on building operations, energy literacy, compliance, and the design choices behind continuous monitoring. Things we keep finding worth writing down.
Sometimes missed by landlords
The Ombudsman's phrase, not ours. Under an extended Awaab's Law, missing it becomes a breach.
Read →Part O overheating, explained: TM52, TM59, and the gap a model can't close
The assessment is a promise made before anyone moves in. Whether the building keeps it is a different question.
Read →Today, the law got teeth. Private landlords: damp and mould is now your problem too.
As of 22 June 2026, councils can issue a £7,000 fine without warning. Here is what changed and what is still coming.
Read →Who pays when energy companies profit? The landlord, the tenant, and the NHS.
Energy costs have tripled. Fines for cold, damp homes are live. The chain of cause and effect leads somewhere landlords cannot control — but are being held responsible for.
Read →HSG274 vs ACOP L8 — what's the difference?
One is the code you must follow. The other is how to follow it.
Read →What counts as evidence under Awaab's Law?
A photo proves a moment. The law asks about the building over time.
Read →Does continuous monitoring meet HSG274?
The guidance asks for temperatures, on a schedule, written down. Sensors do all three.
Read →Damp, condensation or mould — and why the difference matters
Three different problems. Name it wrong and you fix the wrong one.
Read →29 days you can't see: the gap in monthly Legionella checks
A monthly check proves one minute. The risk has the rest of the month.
Read →Six-weekly inspections vs always-on evidence
A walk-round sees one morning. The building changes between visits.
Read →The clip-on revolution
Why we still pay people to hold thermometers.
Read →The void that manages itself
Why an empty flat shouldn't need a weekly visit.
Read →The phantom flush
Why a paper logbook is a terrible shield.
Read →Tenant Wi-Fi is a design flaw
Critical monitoring should never depend on a resident's router.
Read →The self-healing estate
When the sensor and the valve talk to each other, the problem fixes itself.
Read →20mph at midnight
A speed limit is a number; safe driving isn't. Heating is the same — and chasing one 'correct' temperature fights health and net zero at once.
Read →BB101 explained: the CO₂ numbers a school is judged on
And why a one-day survey can't prove a daily-average rule.
Read →Awaab's Law Phase 2 explained
The new hazards, the deadlines, and the one you can see coming.
Read →Awaab's Law starts the clock when you find out
So find out sooner.
Read →Running the building empty
Most buildings heat, cool and ventilate space nobody's in.
Read →When the blueprint stops being true
Rooms drift from what they were built for. The data notices.
Read →Digitising the engineer's brain
The best tool on an estate team is context. It retires when they do.
Read →Every sensor pays its way
If a device doesn't solve a real problem, it shouldn't be on the wall.
Read →Three speeds of building data
Why most sensor readings aren't a midnight problem.
Read →Dashboards don't fix things
A chart has never repaired a boiler.
Read →A sensor is not a system
The "so what" of building analytics.
Read →Not all kilowatts are equal
Why a meter reading is half the story.
Read →The badge isn't the building
Why a paper certificate doesn't tell you what's happening today.
