Measurement Evaluation of façades performance regarding the energy efficiency, durability and quality of thermal and visual comfort
Measurement objects Glass and metal façades, double skin façades, ventilated façades, (switchable) glazing, sun and glare protection systems, daylight redirection systems, façade integrated HVAC components, building integrated PV, solar thermal absorbers, general HVAC components and their integral interaction with the façade, decentralized storage systems, technical mock-ups for complete room concepts

Technical data

Height between floors 3.8 m
Façade surface area 21 × 15 m² (for each test field)
Test cell area (W × D) 4 × 4 m up to 8 × 12 m

Special features

Field measurements of façade and room concepts Short- and long-term experiments with real climate conditions
1:1 full scale evaluations in step with real usage situations Integral consideration of façade, room and building service equipment allow a realistic evaluation of the energy consumption and the visual and thermal comfort.


Extensive basic equipment of measurement and control systems and building services:

  • central supply for heating and chilled water
  • supply air preconditioning by heating, cooling, humidification and dehumidification
  • freely programmable logic controller, providing among others time-controlled internal heat and moisture sources for simulating usage profiles
  • central measurement data acquisition with a web-based analyzing tool (IMEDASTM)
  • web browser access to all functionalities (process visualization, database, evaluation templates, measurement channel lists, etc.)
