General Industry Trends What to expect in the future of hospitality 8

General Industry Trends What to expect in the future of hospitality • Australia’s ‘foodie culture’ is expected to underpin revenue growth in the restaurants industry in the next five years to 2022. • Food service delivery seen as an opportunity and a threat • The evolution of Australia’s pubs from watering holes to gastronomy destinations is seeing publicans draw a growing proportion of revenue from food • Overseas visitors are increasingly turning to Australia for holidays with arrivals increasing by 7.1% in the year to November 2017 • The lower exchange rate is also encouraging domestic travellers (domestic overnight visits increasing by 7.2% ) 9

What are the potential impacts of commercial kitchen exhaust? Health Effects of Particle Matter 13

What are the potential impacts of commercial kitchen exhaust? Environmental Impact – Potential high local impact on urban air quality CFD analysis of the discharge point effluent Nikhil Pubby (Monash University), Estimate the level of compliance for non-residential kitchen exhaust systems in Melbourne CBD and evaluating the causes and 14 effects of increasing air pollution due to these systems – Initial Finding, AIRAH Internship, 2019

What are the potential impacts of commercial kitchen exhaust? Environmental Impact – Potential high impact on urban air quality “The average diesel engine truck on the road today would need to drive for 10 miles (16km) on the freeway to put out the same mass of particles as a single charbroiled hamburger patty.” University of California “ In New York the emissions from char broilers contributed to more than 12,5% of PM2,5 attributable deaths annually in the period 2005-2007. This equates to 400 deaths per year.” Department of Health and Mental Hygiene Published in AIRAH Ecolibrium article on Kitchen Exhaust Design, March 2018 15

What are the potential impacts of commercial kitchen exhaust? Safety Risk - Fire “I believe there was a fire on the grill and it had gotten a bit bigger than they expected,” Mr Carrigg said 16

What are the potential impacts of commercial kitchen exhaust? Safety Risk - Fire • In a generalized scenario: abnormal event will take place on a cooking surface (where excessive heat and flames are present) to create a flare-up. • The most common source of a flare-up is the ignition of cooking oil vapors that come in contact with flames or excess heat. • This flare-up produces high reaching flames that contact and/or quickly heat the hood and filters. • If the flare-up is intense enough or sustained over a sufficient period of time (approximately 2 minutes) the flame can ignite residual grease accumulations commonly found in the hood/duct area. • Second the ignition of combustible materials (generally wood building materials or cardboard storage containers) that are too close to the radiant heat energy being emitted from the metal exhaust duct can cause the fire to propagate 17

CKV Projects: A multitude of different Projects With a multitude of different issues Base Build Design Designing “blindly” with building constraints (star ratings, developer requirements). Hotel Design Major projects with important exhaust requirements which may be difficult to integrate into developments Tenancy Design Specific exhaust system requirements which may be difficult to integrate into a building design. 21
