Convention 6.11 - Zones Without Fixed Conditioning Equipment in Exisiting Buildings

This convention only applies where at least one zone within the building is not conditioned by fixedconditioning equipment, e.g. heating, cooling or mechanical ventilation.

The flow chart below (‘zones without fixed conditioning equipment’ - appendix 10.07) provides the approachan energy assessor should take in these circumstances. Energy assessors should ensure that they canprovide evidence to justify the option selected at each decision point in the flow chart.

Zones must be assessed as seen on the day of the inspection. However, for the purposes of this conventionthe SBEM activity types where zones may not be conditioned (i.e. where no HVAC systems are present)are as follows:

a. Circulation Areas

b. Plant rooms

c. Store rooms and Warehouse Storage

d. Industrial process areae. Car park

f. B1 Workshops

g. Toilet (only if there are no other zones in the building that have an expectation of conditioning)

In these circumstances, the SBEM HVAC type will be identified as ‘Zones without HVAC system’.
