• Established in 1988 by brothers Patrick and Daniel Conway,
Great Lakes Brewing Company became the first microbrewery
in the state of Ohio and today remains Ohio's most celebrated
and award-winning brewer of lagers and ales.
The care that goes into the beer resonates from a
commitment to the community and environment,
otherwise known as the "Triple Bottom Line" - to
engage in economic, social and environmental
practices that achieve a sustainable, yet
profitable, business. These include:
Reducing, reusing and recycling
Changing natural resource use from "Take, Make,
Waste" to "Take, Make, Remake"
Implementing efficient energy practices
Investing in the community through non-profit
organizations
Supporting sustainable urban renewal projects

• The Victorian building at 2516 Market Avenue that houses the
Great Lakes Brewing Company Brewpub was established circa
1865 and became a popular watering hole for Cleveland's
legal professionals and tradesmen. Its most famous patron
was Eliot Ness, former leader of Chicago's "Untouchables"
and the man credited with taking down Al Capone's gang.
As lifelong supporters of environmental causes, the
Conway brothers have incorporated "zero waste
initiatives" into day to day operations. "While we're
strong proponents of operating a manufacturing
enterprise that is environmentally friendly, we also
realize that it has to make financial sense.

• The Brewpub, Gift Shop and Office area is actually three
historic buildings merged: The Market Tavern, McClean's Feed
& Seed Company and the Elton Building.
Above the Brewpub are two facilities known as the Market
Room and the Rockefeller Room, which served as law offices
for a young John D. Rockefeller before he got his start with
Standard Oil.

Great Lakes Brewing Company is a principle-centered,
environmentally respectful and socially conscious
company committed to crafting fresh, flavorful, high-
quality beer and food for the enjoyment of our
customers.

HVAC and Domestic Hot Water System Renovation
Project Area Existing Conditions
• Outside air blocked off for energy savings
• Negative building air pressure from kitchen hood; no MUA
• 8 year old 100 gallon, 500,000 btu under fired hot water tank
• 2nd, 3rd, 4th floor of Elton Building
required new HVAC as part of a total
building remodeling
The brewery consists of six
buildings, three of which
originally served as horse stables
and kegging facilities for the
Schlather Brewing Company .

HVAC and Domestic Hot Water System Renovation
Methodology
• Full site survey, equipment inventory, energy analysis
• Load profiles developed for all areas
• Determine ventilation rates for kitchen
• Determine outdoor air requirements for occupants
• Review solar tax credit information
• Budget and review with owners
We aspire to maintain our status as the premier craft brewery in the Great
Lakes region and are dedicated to uncompromising service, continuous
improvement and innovative consumer education.

Prioritize projects based on need and budgets
- Flue gas entering the space from the negative building pressure
- 40 year old furnaces falling apart
- Elton Building needed new HVAC
- Kitchen hood needs make up air
- Code required ventilation air for the restaurant
- Hot water heater beyond its useful life
- Increased water use due to new dishwashing equipment
- 30% Federal Tax credits for solar
Great Lakes Brewing Company's distribution
area now extends to Illinois, Indiana,
Kentucky, Michigan, New York, Pennsylvania,
West Virginia and Wisconsin.

GLBC operates a beer delivery truck
and a shuttle bus called "The Fatty
Wagon" that runs on straight
restaurant vegetable oil. Results
show that engines running on
straight vegetable oil produce 40%
less soot than diesel and are 25%
cleaner.
