It has been stated that 40% of food in the United States is thrown away – mostly in a food service
environment – and that burdens all food delivered with up to 80% more environmental impact. This
statistic alone is incredibly daunting, which is what inspired me to renovate and redesign a restaurant
into a more sustainable establishment in Monterey, California. My approach to this renovation is
to focus on air circulation, water, energy, material and waste reduction in both short and long term
occasions.

My design philosophy will revolve around continual life cycle assessments (LCA), where I will consider
a broad range of environmental impacts a product can have throughout its entire life cycle. This
includes raw material extraction, sourcing, transport, use and disposal.

TODAY’S CONVENTIONAL RESTAURANT INDUSTRY
TODAY’S CONVENTIONAL RESTAURANT INDUSTRY
Global warming is a real issue, as air and water temperature are indisputably increasing. Climate change has
negative environmental consequences, and it can displace people, threaten the food supply, diminish biodiversity,
and reduce quality of life. Various scientists speculate that at the rate we’re going, the earth could reach an
average temperature of 250 degrees Celsius, which is hot enough to destroy all human, animal and plant life. The
commercial sector is a large contributor this destruction, and the restaurant industry uses 5 times more energy
than other retail, office or lodging industries.

There are nearly a million commercial eating facilities in America, and Americans spend 40% of their food budget
on food consumed away from home. That is nearly half of their food budget. Meanwhile, a restaurant can easily
produce 50,000 – 100,000 pounds of garbage each year, where 95% could be recycled or composted.

ENERGY
In addition to large amounts of food and material waste, the restaurant industry also overuses large amounts of
energy. For example, 1 piece of typical food service equipment can use as much electricity as an entire household.

WATER
Americans use 7 times more gallons of water per capita than the rest of the world. That means that on average,
Americans use about 300,000 gallons a year. With food service operations in particular, the direct cost of heating
water for sanitary uses is obvious, but indirectly energy is also consumed to pump water from treatment facilities to
the local area.

FOOD WASTE
Food waste has great potential to be turned into fertile growing soil, but restaurants often send them to landfills
where they will never be recouped. In addition, landfills don’t get smaller; they only grow larger over time.

BUILDING MATERIALS
Many synthetic materials in chairs, tables, cutlery, cleaning supplies and kitchenware won’t decompose and many
of them contain toxic substances, contaminating through their production, daily use, and disposal. Some materials
have high-embodied energy or chemicals, and as a result, they may emit harmful gases during production and/or
throughout their existence.


SUSTAINABLE RESTAURANT CERTIFICATIONS
SUSTAINABLE RESTAURANT CERTIFICATIONS
In response to the restaurant industry’s negative contribution to our environmental crisis, several organizations
have created sustainable restaurant certifications. Two large organizations, the Green Restaurant Association (GRA)
and the Sustainable Restaurant Association (SRA) both have green restaurant certifications based on a point rating
system.

SRA CERTIFICATION REQUIREMENTS

13. Healthy eating is something that’s increasingly on the agenda at national level and restaurants have a
part to play in helping people make good choices.
14. Responsible marketing means a ban on ‘greenwash’!


CASE STUDIES
CASE STUDY - MIXT GREENS, SAN FRANCISCO
Mixt Greens is a seven-location, chain restaurant across the US designed by William McDonough and Partners.
With a focus on the cradle to cradle concept, Mixt Greens in San Francisco has accomplished the following:
• Packaging is 100% compostable and biodegradable, including napkins, cups, utensils, lids, bags, and straws.
• Through a comprehensive recycling and compost program, Mixt Greens is able to divert 90% of its waste
from landfill.
• Mixt Greens uses renewable energy credits from Renewable Choice to offset energy consumption. All their
restaurants use CFL lighting (set on timers to increase efficiency) and utilize natural daylight as much as
possible.
• All wood products are certified by the Forest Stewardship Council.
• Dual-zone HVAC is used, utilizing natural ventilation as much as possible.
• Recycled and rapidly renewable materials are used where possible, such as tables made from 100% recycled
detergent bottles.
• All of Mixt Greens’ spaces are designed by LEED certified architect William Duff of WD Arch
• Use of zero-volatile organic compound (VOC) paint and concrete flooring with high-fly ash content is used
throughout.
• Mixt Greens uses non-toxic and biodegradable cleaning products from Method, a local manufacturer of green
cleaning supplies.
• Dry cleaning of uniforms and chef jackets is done by SF Green Clean. Primarily geared to the “consumer”
market, Mixt Greens recently reached out to SF Green Clean to offer a commercial contract. Swallow says that
after a about a month of service, both Green Clean and Mixt Greens are very satisfied with the arrangement.


CASE STUDIES
CASE STUDY - RED STAG, MINNEAPOLIS
Red Stag is the first LEED-CI registered restaurant project in Minnesota. According to Red Stag, restaurants use
more energy and water than any other small business, costing them 30-40% of their entire operating budget.
Through using new technologies in the build out of the Stag:
• Water use was cut by approximately 70%
• Energy use cut almost in half.
• Red Stag is the first facility in the country entirely lit by LED lights, which use 90% less electricity than
incandescent bulbs.
• Eureka! Recycling assists them with composting their waste.


COMPROMISES

“Take, for instance, the paper versus plastic bags debate. Retailers such as Whole Foods and even
entire cities such as San Francisco have banned the non-biodegradable plastic variety in the name
of saving the environment. But according to Schenck, who sits on the executive committee of the
American Center for Life Cycle Assessment, a non-profit organization that seeks to build capacity and
knowledge of LCAs, that’s not necessarily such a good thing. An LCA conducted on non-recycled paper
bags shows that because they require the cutting down of trees for materials, are heavier to transport,
and release greenhouse gases when they decompose in landfills, they can actually be worse for the
environment than plastic bags, which are made from an already-existing byproduct of petroleum, are
lighter to transport, and don’t release greenhouse gases in landfills.”
- Rita Schenck, Executive Director of the Institute for Environmental Research and Education

For my restaurant vision, I plan on taking several concepts demonstrated by the Mixt Greens and Red
Stag case studies. While I appreciate the guidance that the varying green restaurant certifications
provide, I do not find the point rating system to be entirely cohesive. I would like my concept to be
more “full circle,” where the system’s big picture is greater than the individual parts.

MONTEREY RESTAURANT BACKGROUND
MONTEREY RESTAURANT BACKGROUND
The restaurant site is located in downtown Monterey, California near the wharf. A restaurant currently exists in the
space, but the current owners are selling their space, and a new type of restaurant will move in. Upon moving in,
the new owners would like to renovate to make the space more eco-effective.

The concept behind the new restaurant is to create a space inspired by casual California hiking trails. The space
will be modern, with subtle elements inspired by nature. The space will not be blatantly “rugged” but rather it should
reflect the overall sense of California’s healthy, active and nature-friendly lifestyle. The new restaurant will serve a
lunch and dinner cuisine, serving food items only grown and raised in the California state.

As the designer, I will do my best to make this space as eco-effective as possible. Throughout the design process, I
will focus on renovating the space to reflect sustainable air circulation, energy, water and material use.


AIR CIRCULATION
AIR CIRCULATION
The kitchen’s mechanical equipment will require the most power and electricity. Kitchen equipment requires more
conditioning of air from heat rejection of equipment use. The following efforts will be made to increase efficiency in
air circulation.

1. Integrate natural cross ventilation into dining rooms and kitchen by use
of extra windows and doors
With grease cooking, exhausted air requires additional air to be
supplemented to the space to be made up. Integrating natural
ventilation into dining rooms in temperate climates in certain parts
of the year can reduce energy costs of conditioning air as well.

2. Geothermal Energy – Install a Synergy3D Radiant Heat System
Radiant floor systems utilize a series of tubing encased in the
floor. By circulating warm water through the tubing, the room is
comfortably conditioned. Since the entire floor acts as a giant
radiator, you’ll experience warm floors and consistent comfort
throughout the room, literally from head to toe. Floors covered in
tile, wood, vinyl or stone are kept toasty warm, even on the coldest
days. Heating is also accomplished using forced air through the
duct system.

Just below the surface, the ground contains vast amounts of
energy that can be used to provide the heating and cooling.
During heating, the system extracts the energy from the
earth, compresses it to a higher temperature, and distributes
it through the site. During cooling, the system extracts
the heat from the restaurant and deposits it into the earth.


AIR CIRCULATION
3. Install Eco-Effective Solarshade Cloths
MechoSystems’ award-winning SunDialer® automatically adjusts
shade positions according to solar penetration/BTU loads and real-
time microclimatic sky conditions. In addition, the AAC/PC SolarTrac
is a building-wide control system which tames the sun’s energy by
optimizing the position of the shades across the building for comfort,
view, and energy efficiency 24 hours a day and 365 1/4 days a year.
This is accomplished by measuring the micro-climatic conditions
around the building and adjusting the shades with reference to the
building’s geodetic location and the calculated angle of incidence,
imposed solar heat gain, and the programmable penetration of the
sun’s energy.

MechoSystems EcoVeil is a Cradle to Cradle certified product that is
100% recyclable, FR and PVC free. It is fully reclaimable, recyclable
and designed for a closed-loop system. It is also Greenguard Indoor
Air Quality certified.

EcoVeil C2C Production Process Advantages include:
• Minimizes solar heat gain and reduces annoying glare.
• Operates to turn on, off, or dims lights, based on the amount of
natural light that the shades allow into the space.
• Saves energy by maximizing the amount of daylight in a space
and thereby minimizes the need for electric light.


WATER REDUCTION
WATER REDUCTION
Restrooms, prep sinks, hand sinks, bar sinks, mop sinks, ice makers, dish washing systems, and water lines are just
a few areas that uses fresh water. To minimize water waste, the following tactics will be placed into the restaurant
design.
1. Install a Sloan AQUS Grey Water Recycling System
The system takes the water that goes down the bathroom sink, filters and
disinfects it, and uses it to flush the toilet. It does not cross connect to the
fresh water system nor does it inhibit the backflow prevention. It simply
uses reused water as the primary source for flushing the toilet then
supplements it with fresh water, as needed.

The system can save up to 6,000 gallons of fresh water per year and
requires only annual maintenance.

2. Install Energy Star Steam Cookers
Energy Star rated units use 90% less water than standard machines. That
can equate to $10,000 in water bill costs.

3. Install Energy Star Dish Washers
Qualified machines are on average 25% more water efficient than standard
machines.

4. Install Low Flow Spray Valves and Aerators
Standard spray valves on industrial faucets in the dishwasher area can
use up to 3 gallons of water per minute. Replacing those with new 1.2
gallon valves can save as much as 90,000 gallons of water.

A properly designed low-flow spray valve hits dirty plates with a higher
velocity than the high-flow valve so the cleaning performance can be as
good or better than the high- flow units. In addition to water savings, the
restaurant will also save energy on heating the water that sprays through
these valves.

WATER REDUCTION
5. Add Low Flow Faucet Aerators to Hand Sinks
Specifying low flow plumbing fixtures and water efficient equipment can
assist in reduced water use.

6. Install Sloan Waterless Urinals
Sloan Waterfree Urinals do not use water, saving the precious resource
as well as sewage and water supply line costs; reducing maintenance and
repair bills; and creating hygienic, odor-free restrooms.

7. Install Solar-Powered Dual Flushometers
The Sloan SOLIS® Collection of solar-powered plumbing fixtures includes
a dual-flush squat toilet Flushometer model. These Flushometers use light
to charge a highly efficient capacitor, providing power even in rooms with
occupancy-controlled lighting.

All Sloan flushometers are made from a high level of recycled material
and are 100 percent recyclable. Sloan is also the first and only plumbing
company to have products – the dual-flush UPPERCUT and the Royal
flushometers, certified Cradle-to-Cradle.

8. Serve Water Only Upon Request
There are nearly 70,000 restaurant meals served each day, and if only
a quarter of restaurant consumers declined water, we’d save millions of
gallons of fresh water everyday.


ENERGY EFFICIENCY
ENERGY EFFICIENCY
Refrigeration, cooking equipment and food preparation equipment can draw substantial power and require a lot of
energy. There are a few fundamental decision decisions I plan to make to significantly reduce energy consumption.

1. Install Energy Star Compact Fluorescent (CFL) Lights
Lighting accounts for about 13% of restaurant energy usage. Energy Star
CFLs use 75% less energy than the conventional incandescent light bulbs.

2. Install Motion Sensors Throughout The Restaurant
Add motion sensors to restrooms, storage rooms, managers office and
other low occupancy rooms.

3. Purchase Energy Star Kitchen Products
Purchasing ENERGY STAR qualified CFS equipment as a package for
new kitchen construction or as a replacement for aging equipment, can
save significant amounts of money and energy on food service operators’
electric, gas, water and sewer bills.

4. Create a Low Energy Menu
Because cooking, refrigeration and food preparation can require a lot
of energy, I will work with the chef to develop a menu that minimizes
substantial use of kitchen equipment.

5. Turn Off Appliances When Not In Use
Train staff to turn off ventilation hoods, dishwashers, lights, cookers,
ovens, etc when not in use.


WASTE
WASTE
40% of food in the United States is thrown away – mostly in a food service environment – and that burdens all
food delivered with up to 80% more environmental impact. The restaurant industry is one of the most wasteful
industries in terms of food and equipment, and the following tactics will be an integral part of the restaurant.

1. Install a Living Permaculture Green Roof
The kitchen will use herbs and vegetables harvested from its rooftop
whenever possible. In addition to food plants, I will work with a landscaper
to also plant native species to create landscape diversity.

Living roofs reduce energy use, create habitat, and capture storm water
runoff that might otherwise flood the sewer system. They also cool the
air, cutting down on the heat island effect of urban areas, a phenomenon
caused by sunlight and heat reflecting off of asphalt and concrete.

There are also air-cleansing benefits of green roofs as well because plants
absorb particulate matter, contaminants, and excess CO2 out of the air,
and birds, bees, and insects are attracted to the new habitat.

2. Compost All Extra Food
This will include separating organic materials with inorganic materials. I
will also purchase a compost system and worm system that can convert
food waste into fertilizer for the living green roof.


WASTE
3. Collect and Recycle Cooking Oil
Work with a recycling company to convert cooking oil into renewable fuel.

4. Use Compostable Take Out Materials and Napkins
Use 100% compostable containers for all To-Go orders.

5. Adjust Menu Options
Offer different portions and sizes so that consumers can choose how
much food they’d like to order. This can significantly reduce food waste.


SUSTAINABLE MATERIALS
Sustainable furnishings and building materials are slowly becoming more popular, so these items are a bit more
accessible. In order to minimize waste as well impact on the environment, the following efforts will be made.

1. Use Reclaimed Materials Whenever Possible
During the construction phase, I plan to reuse construction scrap pieces
for the interior decor. Approximately 70% of all waste arises in the
construction sector from activities such as excavation, demolition, road
construction, and site waste. I also plan to browse flea markets, garage
sales and other second-hand locations to find restaurant chairs, tables
and other decor items.

2. Use Reclaimed and FSC Timber
The FSC Trademark enables companies to choose timber with the
confidence that they are not contributing to the destruction of the world’s
forests. By buying from certified sources they provide an incentive in the
marketplace for good forestry practice.

3. Leverage Local Artists
Support the local community by purchasing art pieces and other interior
items from local artists and craftsmen.

4. Use Non-Toxic, Low VOC Paints
Safecoat Paints have zero VOC, and they also eliminate other potentially
harmful solvents that haven’t been classified yet, as well as formaldehyde,
ammonia and acetone. The products are said to create a “safe coat” on
surfaces, sealing in emissions.

Conventional paints are made from petrochemical-based solvents, which
off-gas toxic indoor air pollutants called volatile organic compounds that
smell funny and may lead to long-term problems over time.


5. Use Cradle to Cradle Certified Products
a. IceStone for Countertops
IceStone is the only gold level Cradle to Cradle® certified surface
in the world. Since our founding in 2004, IceStone has diverted
millions of tons of glass from the landfill, and upcycled that glass
into a highly valued, beautiful product. Surface iQ

b. Surface iQ for Wall Coverings
Surface iQ is not an alternative to vinyl wall covering. It is the result
of a commitment to sustainable design, building on our PVC free
policy to offer clients viable performance solutions.

c. Tarkett Linoleum for Kitchen Floor
Tarkett’s Linoleum xf is the first linoleum in the world awarded with
the Cradle to Cradle® Silver Certificate, as it is made from renewable
raw materials like linseed oil, resin, jute, wood and corks flour.
Linoleum is a renewable material, and does not emit VOCs or other
toxic gases.

d. EKO-Flor for Seating Area
EKO-FLOR™ is significantly stronger, lighter and more durable than
wood. The product possesses superior quality and performance
characteristics including complete resistance to stains, odors,
absorption of oil or liquid chemicals, microbial and insect attack.


Throughout the restaurant renovation process, my goal was to consider the entire life cycle of
each product, operation and function as it relates to air circulation, water, energy, material and
waste reduction. With the ultimate goal of “zero waste,” I believe my efforts were a great first step
towards a more eco-effective design. With an integrated design approach, I tried to include different
stakeholders such as working with a landscaper for the living roof, the restaurant operator for kitchen
design decisions, electrician for proper placement of energy-efficient lighting, architect and air
circulation specialist for proper window placements, staff members for proper training and more. More
importantly, I wanted to include these stakeholders in all meetings, from the very first day all the way
until the end of the project.

Today’s conventional restaurant industry is still learning what it means to be sustainable. However,
a major benefit of renovating this restaurant space is that it will be spreading awareness of the
sustainable movement. The more we continue to “practice what we preach” as well as showcase the
benefits of living sustainably, the greater the chance we’ll have at creating a better, healthier world for
all living people, animals and plants for all of time.
