Do heat pump clothes dryers need to be vented to the outside?

No, the GBCA clarifies that heat pump clothes dryers are not required to be vented to the outside to comply with the Building Services criteria in Credit Achievement under the Energy Use - Residential pathway credit from Green Star Buildings v1 as the moisture is collected rather than vented from the appliance.
