ENVIRONMENTAL ANALYSIS
Planning to build a Green Building? Here's how PassiHVAC can deliver climate-responsive modelling for high-performance designs and compliant buildings.
Environmental analysis underpins informed, climate-responsive building design. PassiHVAC provides advanced environmental modelling and simulation services to optimise building form, façade performance, external comfort, and internal environmental quality—while generating robust evidence for planning, compliance, and sustainability certification.
Our environmental analysis services are routinely integrated with energy modelling, LCA analysis, EPC strategies, and ventilation design, enabling a coordinated, performance-led approach across all project stages.
Climate Analysis for Building Design
Temperature, Humidity and Wind-Driven Design Intelligence
We deliver detailed climate analysis using location-specific weather files to evaluate how environmental conditions influence building performance and occupant comfort.
Typical assessments include:
-
External temperature profiles and seasonal variability
-
Relative humidity and moisture risk implications
-
Prevailing wind patterns and natural ventilation potential
-
Overheating risk indicators and adaptive comfort metrics
Climate analysis directly informs passive design strategies, façade specification, glazing ratios, and natural ventilation concepts. Outputs are frequently used to support dynamic energy modelling and overheating assessments during early design stages.

Solar Analysis
Radiation, Sunlight Hours and Glare Control
Solar analysis is critical for balancing daylight provision, energy demand, and thermal comfort. We assess solar exposure at both the building and façade level to support evidence-based design decisions.
Our solar studies include:
-
Annual and seasonal solar radiation analysis
-
Sunlight availability and façade exposure mapping
-
Glare risk assessment for occupied spaces
-
Testing of shading devices and façade geometry
These outputs feed directly into energy performance modelling, daylight strategies, and façade optimisation studies, ensuring compliance with planning and sustainability objectives.
Wind Study and Microclimate Analysis
Pedestrian Comfort and External Amenity Assessment
We undertake wind studies and microenvironmental simulations to assess how proposed developments interact with local wind conditions.
Our wind analysis typically covers:
-
Pedestrian wind comfort classification
-
Identification of wind acceleration and downdraught risk
-
Seasonal comfort mapping of external spaces
-
Mitigation strategies, including massing, screens, and landscaping
Wind studies are often required for planning approval on medium- and high-rise developments and are complementary to ventilation and airflow modelling at building scale.

Shadow, Visibility and Façade Optimisation
Amenity, Outlook and Environmental Performance
We provide integrated shadow, visibility, and façade analyses to support planning, design development, and occupant amenity considerations.
Scope typically includes:
-
Shadow and overshadowing analysis
-
Visibility and obstruction mapping
-
View rose and view angle assessment
-
Façade optimisation in response to solar, wind and daylight exposure
These studies are frequently combined with energy modelling and overheating assessments to ensure that visual amenity and performance objectives are addressed holistically.
