Configuration of high performance apartment buildings renovation: A constraint based approach

Abstract

This paper looks at the possibility of configuring high performance renovation of apartment buildings by the use of a constraint satisfaction problem (CSP). A new thermal envelope wraps the whole building and allows it to achieve a really low energy performance of 25 kWh/m²/year. This new thermal envelope is composed of rectangular panels, always comprising insulation and cladding, and sometimes including, in addition, doors, windows or solar modules. The panels can be fixed directly onto the walls or onto a metal structure around the whole building. The decision support system, based on CSP approaches, will simultaneously enable the interactive definition of the renovation, the associated bill of material (BOM) and the building site assembly process. The range of knowledge to exploit and to model leads us to integrate into a single decision support system different constraint types, such as classical, dynamic, geometric and global constraints, as well as their filtering methods.

Towards a Metric Between Engineering to Order and Assemble/Make to Order Products in Configuration Situations

“…Therefore, ETO product configuration cannot be supported by a PCS in line with previous ATO/MTO hypotheses and definitions. In the literature, many studies have been reported in the field of ATO/MTO product generic modeling, see [4], [8], [6] or [9]. However, much fewer concern ETO products, see [7], [10].…”

Open Packing for Facade-Layout Synthesis Under a General Purpose Solver

“…One strategy for reducing such energy consumption lies on buildings thermal retrofit achieved either by an internal or an external insulation [9]. Among several options [9], an external insulation may be based on covering the entire building with an envelope made out of rectangular wood-made panels [7,23]. However, some difficulties are present when targeting such renovation in industrial proportions, e.g.…”

Industrialized building renovation: Manufacturing through a constraint-based on-line support system

“…Here, the problem lies on the configuration of rectangular parameterizable panels, and their attaching devices called fasteners, that must be allocated over the facade surface in order to provide an insulation envelope [2]. A configuration solution is a plan which satisfies optimization criteria and a set of constraints (such as geometrical, weight or resources constraints) provided by users and the facade itself.…”
