Exchange Building Model - Programming (ER)

Please ensure that you have read the process mapping document Energy Analysis (PM) before proceeding with this exchange requirement.

The scope of this exchange requirement is energy analysis at the programming stage of a project where programming is considered to include both outline and substantive feasibility. The result of programming is that a feasible approach to the energy analysis of a project has been determined.
A basic building model is defined as 'the set of information that provides both a graphical representation of the design of a building and key pieces of information about the building that can be further used to analyse building performance' (from Autodesc)
During this stage the information available is limited to the basic requirements. These include:

• a building is required
• it should be of a particular type or perform a particular function (several functions may be identified within a particular type)
• it should be located in a particular place and on a particular site (several alternative locations may be identified; each location should be dealt with individually)
• it has an estimated overall area and/or volume requirement OR it is related by a size factor to a similar previous project about which information is known
• there are factors that affect the 'order of magnitude' cost including (but not limited to) items such as
  • expected building configuration (e.g. multi-storey as opposed to single storey)
  • expected structural complexity based on ground conditions
  • expected level of servicing for operational and comfort purposes
  • accessibility of the location
  • labor resource availability

Particular information that is required to determine 'order of magnitude' cost includes:

• the name of the project (for identification purposes) and the units generally used throughout the project;
• the current stage of the project; whilst this is generally optional, it should be mandatory for this exchange requirement
• the location and expected area of a site on which a building is to be located (the shape representation of a site is not necessary for this Exchange Requirement)
• the building or buildings for which the cost is required (at least one building must be specified although the shape representation of a building is not necessary for this Exchange Requirement)
• the area, volume or size factor of the building
• values for factors that may affect the cost
  • factors may be applied to the building directly or individually determined
  • e.g. services costs may be on a volume or size factor basis
• classification of objects for collection into groups and assemblies for costing purposes
