Design documents needed in the assessment ◆
The energy assessment team should have access to design documents for
the buildings they visit. It is not necessary to have everything in electronic
format; having access to the document archive may be as useful.
The material that is usually needed includes
Site plan ■
Building-specifi c layout plans, not necessary in scale ■
Structures data U-values data ■
Mechanical schedules ■
Designed air-fl ow rates ■
Control schematics of air handling units, air-conditioning equipment, ■
and water chillers
Electrical schedules
■
Lighting fi xture and lamp type lists ■
List of buildings and systems connected to the central BMS ■
The site plan will identify all the buildings located on the installation as
well as the energy distribution systems that supply those buildings. The central
heating and cooling plants with the piping that feeds the buildings should be
presented. Also, those buildings scheduled for demolition as well as new build-
