C L I M A + : an early design natural ventilation prediction method
One of the most widely discussed passive building design strategies is using natural ventilation for cooling. In addition to providing fresh air, which enhances occupant productivity and comfort, strategic implementation of natural ventilation in buildings reduces the energy needed for cooling. And …

Cost Modeling Based on Support Vector Regression for Complex Products During the Early Design Phases
The purpose of a cost model is to provide designers and decision-makers with accurate cost information to assess and compare multiple alternatives for obtaining the optimal solution and controlling cost. The cost models developed in the design phases are the most important and the most difficult to …

A conceptual framework for sharing knowledge and information between facility management/operations and building design teams
It is generally accepted that decisions made in early design phases significantly impact the quality of a built project. However, much of the information necessary to assess the validity of early design decisions is not available until later in a project’s lifecycle. The impact of early design …

Systems and control problems in early systems design
… concerned with the evaluation of properties of early design models, the control structure selection and the representation and properties of composite system models. The work is motivated by the need to introduce a Systems and Control Theory based framework for early design stages of the overall …

An interactive performance-based expert system for daylighting in architectural design
Design practitioners are increasingly using digital tools during the design process; however, building performance simulation continues to be more commonly utilized for analysis rather than as a design aid. Additionally, while simulation tools provide the user with valuable information, they do not …
