The better energy-efficient building components of today have one major flaw: The loss of efficiency through improper usage during the building process can be dramatic. ACCEPT will ensure the proper usage of the components during the building process with the help of Smart Glasses (Optical Head Mounted Displays, e.g. Google Glass or Epson Moverio ). The Smart Glasses will unobtrusively provide the workers on site with guidelines exactly when needed, while common methodologies - defined by the site manager - for all workers can be incorporated to standardize and coordinate the overall working activities. The execution details brought to the construction site by ACCEPT can be customized for the working site, the building components and the different contractors to even bridge language barriers with ease. In this way it is possible not only to minimize the loss of efficiency due to thermal bridges or bad air-tightness, but also to increase the overall efficiency, reliability and productivity of the construction processes.
Relevant data will be aggregated passively on the construction site by workers wearing Smart Glasses as well as actively using different sensors accessed through a Smartphone operated by the site manager. In addition, visual annotations can be attached to objects in order to exchange context-based information between workers; bringing the Wiki idea to the construction site. The data is processed in a cloud environment with self-inspection methods to determine important characteristics (such as U-values) as well as to monitor the coordinated progress of different parties cooperating in the building process. Thereby a sophisticated tool for the quality control during the building process is provided which guarantees that the energy performance at commissioning stage will meet the one expected at design stage. ACCEPT will reach the following key objectives:

• Improving the final thermal, acoustic and energy performance of buildings by providing sophisticated quality assurance tools, which will be used actively or passively by different stakeholders during the construction process
• Reducing the mismatch of energy performance between design and commissioning stage by providing guidelines to apply the sophisticated quality assurance tools mentioned before
• Providing guidelines and methodologies during the construction process by transferring knowledge between the different stakeholders of the construction process
• Increasing the efficiency, reliability and productivity of a construction processes

2. A Site Manager App (SiMaApp) running on a mobile device, which allows to remotely coordinate the working process as well as collect additional data on site by different sensors. (Pillar II: Agile Project Coordination for Bridging Heterogeneity)
3. An interactive web-based Dashboard as a monitoring and quality assurance solution. The Dashboard will use self-inspection methods to determine important characteristics such as U-Values. (Pillar III: Adaptive Quality Assurance with Self-Inspection Features)
