The HVAC system in a real building was simulated by the energy simulation tool being developed (Ito et al. 2007, Sugihara et al. 2007). In order to confirm the practical utility of the tool, the studies are conducted on each phase: Program/Planning/ Design phase, Construction phase, Pilot-Operation phase and Operation phase.

This paper describes the conversion of equipment characteristics into mathematical formulae, verification of the precision of said mathematical formula, and a concrete simulation tool. The main feature of this simulator is that operation of equipment is solved using temperature and flow, not calories. However, the characteristics of equipment are described using as simple a formula as possible. These formula are verified with actual values, and the simulator was confirmed to provide sufficient accuracy for energy management.

The importance of LCEM (Life Cycle Energy Management) has been recognized from the view of life cycle energy saving of sustainable buildings. The purposes of this research are proposal of an LCEM framework and development of prototype HVAC system simulation tools for LCEM. In this paper, necessity of energy simulation tools for LCEM is discussed, and the outline and solution method of the simulation tool are shown.

A computerized model, CoED (Collaboration Enhancing among Design participants) was developed, focusing on the relationships between designers, design variables and design phases. It uses optimization, based on Genetic Algorithm, to decompose these relationships into workgroups of relevant designers and design issues, for each design phase. It identifies intersecting issues between designers, allowing them to be aware of the effects of their decisions on issues relevant to others and enlightening tradeoff options for each one so that conflicts may be avoided and controlled.

A computer system for enabling designers and entrepreneurs a simple, convenient and quick manner to select different building technologies for the building's envelope is presented. The selection is achieved by examining the profitability of each alternative, while presenting its performance ability on the basis of a large number of criteria. This paper looks at the application of multiple criteria decision making (MCDM) techniques in the assessment of environmentally sensitive construction methods.

Progressive design practices are increasingly cognisant of the potential of building energy simulation to assist the delivery of energy efficient, sustainable buildings. However, the success of any building performance assessment hinges on the capabilities of the tool; the collective competences of the team formed to apply it; and, crucially, the existence of an in-house framework within which simulation can be applied with confidence (McElroy and Clarke 1999).

This paper describes the use of transient building performance simulation in order to develop design guidelines for educational buildings in Turkiye. The premise of the work is that design decisions taken during early stages of the building process have a large impact on the performance of the resulting building and hence need solid underpinning. Yet straightforward application of building performance in these early stages has proven to be difficult.

EnergyPlus models follow fundamental heat balance principles very closely in almost all aspects of the program. However, the simulation of building surface constructions has relied on a transfer function transformation carried over from BLAST. This has all the usual restrictions of a transformation-based solution: constant properties, and fixed values of some parameters.

Over the last three decades the use of building performance simulation (BPS) tools has increased but its ability to support building design is still limited. State of the art BPS tools have the potential to be used more extensively during the entire design process if their current capabilities are expanded.
