ASP-BP Application Service ProvisionBest
Practice

• European framework
• 6 projects focused on ASP technology-based
  applications in different industrial field.
• Duration 2 years
• Funded by the European Union under the IST
  programme within Fifth Framework programme.

3
Objectives

• To adapt two thermal behaviour simulation
  software
• GiD-FAUST (CFD)
• SIMCAD-TRNSYS
• (Dynamic Transient Simulation)
• To create a new ASP model STEDI
• (version of GiD-FAUST coupled to SIMCAD-TRNSYS)

4
Objectives

• To demonstrate the use of this applications
  through Intensive validation and dissemination
  plan.
• Essential role of end-users in the project

8
Identification user requirements and objectives

• Define the end-users needs
• Define required tests and measurements needed to
  ensure a good performance and reflect the
  benefits of STEDI
• Information exchange platform

9
Training and initial evaluation

• Evaluation of TRNSYS and GiD-FAUST by the second
  level end-users (architects)
• To know the features offered by SIMCAD-TRNSYS and
  GiD-FAUST.
• To have enough knowledge for a proper
  continuation of the project.

10
Specification of second level users needs

• Fully specifying the second level user needs
  concerning GiD features and the web computing
  service.
• Starting points information and requirements
  defined in Task 3
• Experience gained during the initial evaluation
  period in Task 4

11
Conclusions

• The more important factors for the program hit
• producing useful outcomes
• simple to use
• quickly understandable
• Pre-checking tool at the early design phase

12
Outcomes definition

• Graphical Outcomes CFD Computations
• Room distribution temperature
• Distribution of air velocity vectors
• Distribution of comfort values

13
Outcomes definition

• Global Building results
• Heating Cooling loads
• Average Daily temperatures
• Hourly zone temperatures

14
Outcomes definition

• Evaluation Process
• Identification of critical situation in the
  overall building graphics
• Analyse the CFD of more critical situations

16
Plans for STEDI v1.0

• First version, May 2003
• Validation and test until October
• Revised version October 2003

17
Project Risks

• Dissemination
• know about the existence of the ASP model.
• Links to the STEDI Web page on the most important
  Web-Sites
• Publicity in architectural reviews.
• Clarity
• The Potential users of the STEDI service have to
  be attracted by STEDI.
• The risk is that potential users wont understand
  the aims of the service.

18
Project Risks

• Economical Risks
• Cost of the ASP service.
• Internet Connection
• Minimum standard of internet connection.
• Technical Risks
• Too complicated to draw the building Model
• Guide for STEDI. Insufficient libraries.
• Outcomes not right or incomprehensible.
