How much exhaust is enough ?
Open the door and then switch on air conditioner!
Duct is as big as the hood?
Do you open the window of your car when it’s 40°C o utside and you have the AC on?
Supply Outside Fresh Air
Supply Air Conditioning Air
Exhaust Air
Lots of $$$ goes through the hood…why should we care?
The key is to minimize exhaust rates without compromising efficiency.
less exhaust air =
Less outdoor supply air=
less Air-Conditioning costs=
Less heating costs (wherever applicable)
=Less fan motor energy consumption
=Less HVAC utility costs
=More profit
1 m3/h exhaust less = 1,00 to 1,20 USD saving in energy cost per year depending on climate conditions
HVAC & kitchen equipment contributes up to 80% of total restaurant energy consumption!
40…60%
40…60%
10…15%
5…10%
HVAC Kitchen Equipment Lighting Cooler Freezer & other
Start from the heat source: cooking equipment!
• Low efficiency appliances with high energy output add more heat to space, require higher ventilation rates and result in higher HVAC energy consumption.
• Adding 10 kW to appliances energy input may double contribution to the whole building energy consumption to 20 kW
• Kitchen energy consumption is driven primarily by cooking process & equipment
Use more efficient cooking process!
• Convection ovens
• Use best-in-class ENERGY STAR equipment www.fishnick.com/saveenergy/rebates
• Induction cooking
• When possible prefer electrical versus gas
• Even when it comes to charcoal cooking or flame cooking always prefer closed equipment versus open.
How to reduce HVAC energy ?
• Use high efficiency hoods, but all hoods are not made equal.
( Ask for efficiency test following ASTM 1704 is the only independent test today that can quantity and prove energy efficiency. Standard Test Method for Capture and Containment of Commercial Kitchen Exhaust Ventilation Systems)
• Avoid drafts with:� proper balance between exhaust and supply � low velocity diffusers instead of spot cooling, linear grilles or 4 way-diffusers
• Position cooking appliances close to the walls, avoid island installations when possible.
• Enclose appliances with the walls, or add side-skirts to the hoods.
• Use Heat Recovery where applicable
• Optimize transfer air from dining room to back of house kitchen
• And finally: use Demand Control Ventilation (DCV) !!!! That’s the future
Professional kitchens are not static environments, why the ventilation should be?
Hospital Kitchen, 3 PM
Cleaning, no cooking but exhaust is at 100% !
What is DCV ?
DCV is a control system that regulates hood exhaust airflow and make-up air based on demand from cooking process.
Appliance status Hood status
Cooking Operates at design
airflow
Idle Modulates below design
airflow
Off Off
DCV becomes mandatory in USA!
ASHRAE Standard 90.1 - 2010If a kitchen/dining facility has a total kitchen hood exhaust airflow rate greater than 5,000 cfm (8500 m3/h, 2360 l/s) then it shall have one of the following:
a) At least 50% of all replacement air is transfer air that would otherwise be exhausted.
b) Demand ventilation system(s) on at least 75% of the exhaust air. Such systems shall be capable of at least 50% reduction in exhaust and replacement air system airflow rates, including controls necessary to modulate airflow in response to appliance operation and to maintain full capture and containment of smoke, effluent and combustion products during cooking and idle.
c) Listed energy recovery devices with a sensible heat recovery effectiveness of not less than 40% on at least 50% of the total exhaust airflow.
How it saves energy on heating and cooling?
NON CONTROLLED ventilation operates typically
all day at 100%...
... As the heat generated by the cooking appliances
varies a lot...
Massive energy waste
How it saves energy on heating and cooling?
A MUST for any DCV system...
the capture efficiency ofthe canopies andventilated ceilings
has first to be optimised...
A technology like Capture Jet requires 30 to 40% less exhaust air
High Efficiency Hoods
How it saves energy on heating and cooling?
D.C.V the exhaust airflow follows the real usage of the cooking
appliances
High Efficiency Hoods
DCV
M.A.R.V.E.L.
High Efficiency HoodsTraditional Canopies High Efficiency + D.C.V
How it saves energy on heating and cooling?
The cheapest energy is the one you don’t use!
Association of Demand Controled Ventilation and High
Efficiency hoods
Up to 50% reductionexhaust airflow rates
D.C.V with balancing dampers make a big difference!
Systems that couple multiple hoods to a single exhaust fan need a means ofindependently regulating exhaust airflow for each hood to maximize energy savings

Cold Mist On Demand Technology
Cold Mist technology is the best filtration
solution for solid fuel appliances and heavy
duty cooking equipment (Charbroiler,
Chinese woks).
→ Creates a cold water Mist inside the exhaust plenum
→ The smoke is forced to pass through it
→ FOG (Fats, Oils and Grease), particles and part of the
odours are trapped into the cold water by condensation.
The Filtration Solution for Solid Fuel: Cold Mist technology
The cold Mist acts as a spark arrester and air cooler
→ Cold Mist takes sparks heat away through adiabatic
and evaporative cooling
→Temperature is reduced to an acceptable level
→ Greatly reduces the risk of fire propagating in the
ductwork
→ “Burning on” of the cooking grease is suppressed.
Cold Mist is also the SAFEST technology for Solid Fuel
How to make it sustainable: Mist On Demand Technology!
Infrared Sensors control in real time
cooking activity...
→ Infrared sensors control in real time the thermal
signature of each type of cooking appliance
→ Smart algorithm activates the cold Mist when its
strictly required (e.g. at oven door opening, cooking
starts)
→ No continuous Mist
→ The Mist stops automatically when the cooking
appliances emissions stop (e.g. at door closing)
RESULT = up to 80% Water consumption savings
compared to continuous mist!
No expensive and hard to maintain recirculating water
systems, no chemicals…
Hot Water Wash technology makes it
maintenance free.
→ An automatic wash cycle thoroughly cleans the
inside of the exhaust plenums
→ Removes all grease and residue by a combination of
hot water and detergent
→ Maintenance of the Mist canopies limited to the
external surfaces
Cold Mist On Demand technology is combined to Hot Wash
3528$ savings on water consumption measured at University College of Birmingham (UCB)

Variation in fan rotation speed47% savings in fan power consumption compared to traditional systems
Accountability: Hilton Bucharest results with DCV
The electricity consumptionof a centrifugal fan is proportional to the cube of
the rotation speed. Consequently, a fan that operates at 78% speed (average) has only 47%
of the nominal powerconsumption.
