The document outlines various technical services provided related to building facades and glazing including thermal analysis, daylight analysis, structural calculations, ventilation assessments, testing, and accreditations. Thermal analysis includes U-value calculations and infrared simulations, while daylight analysis covers sun path diagrams, daylight calculations, and solar shading studies. Structural services encompass wind load calculations, material resistance assessments, and deflection checks for aluminum systems. Testing and standards affiliations are also listed.
