A: Design and planning methodology

A05 - Building physics system concepts and planning methods for construction and operation of adaptive structures

Adaptive, ultra-light structures challenge building physics planning, because the known design principles of previously widespread and established engineering tools for building and HVAC equipment simulation are only limitedly or not at all applicable anymore.

The aim of project A05 is to develop building physics system concepts for adaptive structures and planning methods for their design and operation.

IABP

The project investigates the following scientific questions:

  • How do adaptive components affect the building physics conditions in the rooms?
  • What are the consequences of transient indoor climate conditions concerning thermal comfort?
  • How can comfort be evaluated and predicted under transient conditions?

In order to ensure the usability of adaptive rooms or buildings, a comfort model is to be developed in which the transient boundary conditions can be adequately constituted and the overall user comfort can be assessed and predicted. In order to validate the developed transient comfort model, various scenarios will be tested by subject experiments in HiPIE laboratory at Fraunhofer IBP. The measurement and survey results will be compared with the predicted values from the model.

ISYS

The project investigates the following scientific questions:

  • How may adaptive components be integrated into existing control concepts?
  • Which requirements on the actuators and sensors result from the interplay of adaptive components and a transient comfort model?

The goal is to create a modular and parametrizable simulation database for the analysis of various configurations. For this purpose, dynamic models for system components with building physical adaptivity will be developed.

An active control concept is necessary to utilize the interrelations between system components determined in the model and to meet user comfort requirements. It will be developed based on a new synthesis model and serve to ensure user comfort within the rooms.

Requirements for actuators and sensors for adaptive components are derived from the investigations in A05. The developed control and regulation concepts are tested and validated in simulations using exemplary room models. In the further course of the project, the control system will be implemented in a sample unit of the demonstrator and validated experimentally.
