Building Envelope Physics Analyses

 

Thermal

• thermal transmittance (U-value) of building envelope components (windows, curtain walls, walls)
• thermal bridging analysis (linear and point thermal transmittance)
• surface condensation and mould growth
• interstitial condensation analysis of building envelope components (EN ISO 13788 and EN 15026)

Solar

• peak and cumulative solar exposure on building envelope
• glass optical properties (solar and light)
• assessment of shading devices

Daylighting

• daylighting availability (Daylight Factor, Daylight Autonomy, Useful Daylight Illuminance)
• glare and visual comfort

Whole building

• dynamic building energy simulation for quantifying the impact of the building envelope design on energy performance (heating and cooling loads) and thermal comfort

Façade Design Input

 

Concept design

Solar exposure analyses can inform the massing of the building and the building envelope initial design, including orientation and inclination, glazed areas, shading type and position.

Whole building analysis quantifies the impact of the building envelope on energy performance and comfort.

Dedicated component modelling indicates the thermal performance of different façade options (windows vs. curtain walls or double skin façades).

Glass choice

Assessing the optical properties of glass assemblies and the solar factor to solve the challenging target of matching appearance and performance.

Innovative materials

Advice on performance and procurement of transparent materials, insulation and emerging technologies.

Code compliance

Façade design support to achieve Building Regulations and sustainability rating scheme (BREEAM, LEED, WELL).
