Advertisement consent is decided on amenity and public safety alone, and brightness sits inside both. Here is how luminance limits, environmental zones and digital display conditions work.
Light spill onto bat commuting and foraging routes
Lighting near bat roosts and commuting routes sits inside protected species law, not amenity policy. Here is how the constraint is set and how a lighting design meets it.
When dynamic olfactometry is needed for an odour case
Olfactometry produces the only measured odour concentration, but it is rarely proportionate. Here is what the method involves and which planning cases actually need it.
Separation distances for waste and composting odour
A separation distance tells you which assessment a waste or composting proposal needs, not whether it will be permitted. Here is how odour and bioaerosol evidence is actually built.
Air quality neutral and air quality positive requirements
Air quality neutral is a benchmark comparison, not a modelling exercise. Two benchmarks, two sources of emissions, and a design response that is mostly decided by the heating strategy.
SOAEL and LOAEL: using the noise effect levels properly
The effect level hierarchy comes from the Noise Policy Statement for England and deliberately carries no national figures. That is a feature, and most submissions handle it badly.
Glint and glare assessment near an aerodrome
Glint and glare modelling predicts where reflections from panels or glazing will fall across the year, and pilots and controllers are the receptors that decide it.
Ammonia deposition from livestock near designated sites
Ammonia travels further than odour and is assessed against habitat thresholds rather than human receptors, so a unit can be screened in by a site 10 kilometres away.
Odour from a poultry unit: modelling and distance
England sets no statutory separation distance for intensive livestock. What decides a poultry odour case: ventilation discharge, muck storage and the cleanout peak.
What an acoustic barrier actually achieves
Acoustic fences deliver far less than clients expect. Path difference, surface density, gaps and position explain why, and what to do for upper floor windows.
Night deliveries and servicing noise at commercial sites
Delivery noise wakes neighbours even when the measured average looks fine. Event based assessment, yard layout, reversing alarms and workable hours conditions.
Statutory nuisance after planning permission is granted
Complying with your planning conditions does not answer an abatement notice. The two regimes, the appeal deadline and the records that support a defence.
Wind turbine noise and the ETSU-R-97 condition
Wind turbine noise limits vary with wind speed rather than sitting at a fixed level. How the limits are derived, what the amplitude modulation condition does and where the method is challenged.
Designing a dark corridor for bats across a site
Bat corridors fail on lighting spill, not on lighting standards. How the ecologist sets the target illuminance and how the lighting design is tested against it.
Sky glow, light trespass and luminaire intensity limits
Upward light ratio, vertical illuminance at windows, luminous intensity towards an observer and surface luminance are separate controls. An assessment reporting one lux figure fails three of them.
Choosing the right ILP environmental zone for a site
Zone selection decides every numeric limit in a lighting assessment. The E1 to E2 boundary, over-classification in towns, and how to handle a site that straddles two zones.
Biomass boilers, emissions limits and smoke control areas
A biomass installation raises two separate approvals: the planning position on the flue, and Clean Air Act 1993 controls on smoke, chimney height and emissions. They run on different timetables.
Nitrogen dioxide modelling and model verification
An unverified road model tells you what the equations produce, not what the street does. Verification is where every competent reviewer starts.
Construction dust risk assessment to the IAQM method
A site can be high risk for trackout and low risk for construction. Scoring the four activities separately is what the method is for.
What an Air Quality Management Area declaration means
An AQMA says a national objective is unlikely to be met somewhere inside a boundary. It changes the evidence expected, not whether development can happen.
Odour and separation distance for anaerobic digestion
Digestion happens in a sealed vessel. The odour comes from reception, clamps and digestate storage, and modelling rather than distance decides the case.
Odour control for a hot food takeaway extraction system
Hot food takeaways are refused on the flue far more often than on the use. Odour risk scoring, abatement stages and termination height decide the outcome.
Vibration from construction and BS 6472 response levels
Vibration people find intolerable is roughly an order of magnitude below the level that damages a house. Almost every complaint is about annoyance and almost every claim is about damage.
Construction noise, BS 5228 and section 61 consent
A section 61 prior consent fixes the noise terms for construction works before they start. Without one, the council sets those terms reactively, after the first complaint.
