Get planning approval right first time
Planning authorities want evidence. Evidence that your scheme will not compromise daylight for neighbours, create wind hazards at street level, or leave future residents overheating. We provide that evidence, and getting us involved early means the same analysis that satisfies planners also feeds back into better design decisions.
At IN2, we maximise first time planning approvals
Getting the right analysis done early does three things:
- It gives planning authorities clear, methodologically sound data
- It identifies design constraints before they become planning conditions or objections
- It informs facade, ventilation and landscaping decisions that make the project better
Each service can be delivered independently or as part of a coordinated planning support package.
Daylight and sunlight modelling
Satisfy planners and protect residential amenity on high-density schemes.
High-density urban proposals face close scrutiny of how they affect daylight and sunlight, for future occupants and for existing neighbours. We model both using BRE methodology and produce reports that planning authorities can rely on.
Where project geometry allows, we work directly from Revit models, which cuts remodelling time and reduces the risk of inconsistency between the design and the analysis.

Wind and pedestrian comfort
Show that your scheme will not create hazardous or uncomfortable wind conditions at ground level.
Tall or geometrically complex structures can significantly alter local airflow. We assess pedestrian comfort using CFD simulation, combining 3D massing models with SimScale or Phoenics/Flair, and evaluate results against Lawson Criteria. The output is a clear, plannable comfort classification for each area of your development.
TM59 overheating assessments
Demonstrate that residential units will be comfortable now and under future climate conditions.
Overheating assessments are increasingly required at planning stage for residential developments. CIBSE TM59 is the accepted methodology across Ireland and the UK. Our assessments account for occupancy patterns, ventilation strategy and building fabric performance, and cover both current and projected future climate scenarios.

Design optimisation and mitigation recommendations
Planning submission support
M&E planning design services
Confirm technical deliverability before your planning application is submitted.
Late-stage M&E redesign is one of the most disruptive and expensive problems a development project can face. We run feasibility studies at planning stage to confirm infrastructure capacity and flag constraints before they become planning conditions or construction problems. Site visit findings feed into SiteWorks survey reports, shared directly with utility providers and planners.
External lighting design
Balance safety, security and ecological protection. Document it for planners.
External lighting is a material planning consideration. We develop lighting strategies covering illumination levels, glare control, light spill, dark sky compliance and bat-sensitive zones, with visualisations ready for planning submission.
Beyond compliance: what our analysis feeds back into design
Our planning assessments do more than satisfy regulators. The same analysis informs better design:
- Facade and glazing strategy: maximising daylight while managing solar gain and overheating risk
- Natural ventilation feasibility: confirming where passive approaches work before mechanical systems are over-specified
- Landscaping and public realm: using wind and sunlight data to create genuinely usable outdoor spaces
- External amenity performance: making sure terraces, courtyards and roof spaces work for the people who use them
