Constraint-based plant room design

摘要

Object-based CAD programming is used to take advantage of standardisation to handle the schematic design, sizing, layout and (potentially) pipe-routing for LPHW (Low Pressure Rot Water) plant rooms in buildings. From a simple specification of the plant room geometry, and the heating load in kw, our software proceeds through a number of steps. First the standard number and size of modular boilers, pumps etc. is determined from the heat load. Then a compatible optimising 3D variational solution is generated, using Constraint Logic Programming. Our approach is highly interactive. Modifying the topology of the solution is done directly through the graphic interface.
