Option Appraisal
The options available to satisfy functional, technical, operational and end-users’ needs and the extent to which these can be practically achieved should be assessed.
Options should allow for the measurement of environmental, social, security and economic performance, and comparison with the required outcomes.
Design & Construction Team Requirements
In particular, the design and construction team should:
- Indicate when alternative solutions (e.g. designs, materials, products and systems) are available.
- Inform the Appointing Party which solution (or combination) optimizes energy use and minimizes CO2 emissions and whole-life cost.
- Be explicit when deciding on any matter that could impact on operations, in particular energy use, CO2 emissions, water consumption, waste disposal and whole-life cost.
- Obtain information from manufacturers on the operational costs (including maintenance), breakdown frequency, lifetime of system components/parts (including the energy consumed by them) and other information required by the Appointing Party.
- Obtain current lead times for building services engineering systems and other major components and systems.
