2. Current and upcoming assignments
Analyze the energy consumption of fume hoods in the experimental building of the University of Tokyo using Excel
Make a poster and analyze the situation
Please note:
Due to being very ill for the past week and therefore not receiving the task until 2 days ago, I have been unable to complete this task to the best of my ability
I have yet to complete the laboratory tour due to being ill, and therefore cannot take the model or type of fume hood used into consideration (e.g. combination, vertical), something which I will do as soon as possible
In addition, I have been creating surveys on IARU student attitudes and impressions towards sustainability at the University of Tokyo as well as attending a course on Sustainable Urban Management, both of which I hope will help me complete the assignment

3. Research: What is a Fume Hood and why does it matter?
a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts.
Scientific research is energy intensive; research uses more energy per m² than any other activity in Universities. Scientific equipment, research and associated activities are also typically responsible for high levels of water and chemical use and can result in the production of vast amounts of waste.
Fume Hoods are a massive contributor to this, because they constantly remove very large volumes of conditioned (heated or cooled) air from lab spaces, they are responsible for the consumption of large amounts of energy (Mills, 2006)
Fume hoods are a major factor in making typical laboratories four to five times more energy intensive than typical commercial buildings (Mills, 2006)
It is estimated from currently available data that laboratory equipment accounts for more than 30% of total power consumption at the University of Tokyo
Ensuring energy efficient fume hoods are therefore one of the strategies used to create sustainability in the laboratory by maximizing laboratory equipment efficiency minimizing electrical distribution losses, and maximizing ventilation efficiency
Fume hoods are box-like structures, often mounted at tabletop level with a movable
window-like front called a sash. Fume hoods capture, contain, and exhaust airborne
hazardous materials, which are drawn out of the hood by fans through a port at the top of
the hood. Laboratory fume hoods are ubiquitous in pharmaceutical and biotechnology
facilities, industrial shops, medical testing labs, private research labs, and academic
settings. Their fundamental design has gone largely unchanged for the past 60 years
(Saunders 1993).
As depicted in Figure 1, overall fume hood energy use is the product of a number of
support systems, including: supply and exhaust fans, space-cooling energy, space-heating
energy, and (in some cases) humidification or de-humidification and terminal reheat. We
developed an engineering model (Figure 2) to perform baseline analysis and test the perhood
and national impacts of energy efficiency improvements.

Outcome
Harvard University
The campaign combines various components of competition, prompts, communication, goal setting, incentives, and feedback.
Resulted in a sustained ~30% reduction in fume hood exhaust rates as a result of increased attentiveness to fume hood sash height. The total pre-campaign exhaust from the 150 VAV fume hoods monitored was 85,000 cubic feet/minute (CFM), and the post-campaign average 59,000 CFM. This translated into cost savings of approximately $180,000 per year, and a greenhouse gas emission reduction of 300 MTCDE (metric tons carbon dioxide equivalent).
M.I.T
The first fume hood behavior intervention occurred when Chemistry Department’s EHS Coordinator reinforced the importance of closing fume hood sashes at the regularly scheduled EHS laboratory representative meeting, reinforced by .
Average sash height is lowered by 26 percent estimated $41,000/year. Sash position during inactive periods is lowered from 9 to 6 percent open. However, energy savings are substantially less than original expectations due to combination sashes.
North Carolina State University
Campus presentations highlighting the University’s responsibility to conserve energy and provide safe working conditions with the goal of educating scientists and research assistants on proper lab protocol and ways to reduce their carbon footprints. Sash opening labels have been placed on all fume hoods on campus to serve as constant reminders for all lab users. In addition to these campaigns, periodic surveys are conducted to inventory which labs are practicing correct lab safety procedures. These surveys also highlight buildings with high energy consumption where further monitoring or outreach is needed.
University of British Columbia
Campus and Community Planning partnered with BC Hydro to host the 4th Annual Shut the Sash energy-saving competition focusing on laboratory fume hoods.
Overall, participating lab teams achieved a 64 per cent decrease in sash height, resulting in 6,780 kWh of electricity savings, 210 GJ of natural gas savings, and reducing greenhouse gas emissions by 10.6 tonnes
Behavioural programs to reduce energy use: A number of colleges, universities, and other research institutions run or have run programs to encourage lab users to reduce fume hood energy consumption by keeping VAV sashes closed as much as possible. These programs typically use social marketing tactics such as placing stickers or magnets on VAV fume hoods to prompt users to keep them closed, providing feedback to lab users on the amount of energy consumed by fume hoods, and running competitions in which labs compete to see which building or lab can achieve the largest percentage reduction in fume hood height or energy consumption. Organizations that have run behavior programs to reduce fume hood energy use include

5. Institution Strategy Outcome University of California, Davis
600 vinyl stickers were installed on the exterior sidewall of fume hoods in ten buildings at UC Davis. The sticker uses a traffic light color scheme, with a red zone above 18 inches, and a large arrow pointing down with the words, “More Safe, Less Energy” changing from yellow at the midpoint to green at the bottom when the sash is closed completely.
Visual surveys of sash-position status were conducted before sticker deployment, about 2 months after sticker installations, and again in spring, 2011, to assess persistence. Survey results showed % compliance 22 months after installation with no additional reinforcement of closure.
University of California, Irvine
Uses a three-pronged approach. The first method is direct education, in which teaching assistants (TAs) are asked to encourage their students to close the hoods before leaving the labs. The second approach is placing “point-of-decision” reminder stickers on the hoods themselves, explaining that a closed fume hood saves up to 50,000 lbs of CO2 a year. The third method is an incentive-based competition among three buildings that contain fume hoods. The building that wins the competition wins a catered luncheon for its professors and lab users, and an energy-efficiency certificate provided by the Green Campus Program.
In 2007, the Fume Hood Use campaign won an award for “Best Practices in Student Energy Efficiency,” at the sixth annual Sustainability Conference at UC-Santa Barbara, beating all other PowerSave Campus Programs in the UC system. The PowerSave Campus team estimates that the Fume Hood Use campaign saves over 80,000 lbs of CO2 and $13,000 every quarter.
University of California, Los Angeles
As its first initiative, UCLA EH&S's Laboratory Energy Efficiency Program (LEEP) jointly sponsored a competition with the Alliance to Save Energy's PowerSave Campus Program to encourage reduced fume hood sash heights in research laboratories. The first fume hood competition took place in the Molecular Sciences Building (MSB) during Fall 2008 and included about 230 fume hoods.
Overall, the competition saw a 40% sash height decrease from 13.4” to 8”. In order to identify the lasting, long-term behavior change, LEEP and UCLA PowerSave Campus conducted follow-up audits each month after the competition. Sash heights were measured throughout one week, using the same method for recording baseline measurements. The follow-up data showed that MSB’s new average sash height was 7.8”—a 5.6” decrease from baseline measurements. Ultimately, this 40% reduction translates into an annual estimated savings of 1,415,278 lbs of CO2 emissions and $149,730. Several additional competitions have been held following the success of this original one.
University of California, Berkeley
Educates lab researchers to close the sashes on fume hoods when they are not in use to reduce energy consumption and improve air quality. The program uses stickers, flyers, and s to disseminate information. It also involves a competition to see which lab can “Shut the Sash” most consistently.
Contributed to actual hard metrics.

6. Behavioral Campaign Ideas
This design can be combined with other informative materials and data. Could potentially be put on stickers, that could then be placed on the fume hood.
Catchy and memorable slogan can easily be combined with social media campaign efforts.
Visually impactful yet explanatory visual.
Space to insert either University of Tokyo and/or Green Lab logos.

8. More Behavioral Outreach Methods
Photo campaign
Take a fun picture of yourself closing the fume hood for the chance to win a prize
Bi-monthly s sent to all lab members
Mid-month updates let the labs know if they are on track to meet their goal
Posters with up-to-date charts of the results could be posted every month on each lab’s bulletin board.
Each lab could be appointed a volunteer within their lab to emphasize the importance of keeping unused sashes closed and to report any problems with the hoods promptly.
Presentations and recognition at a bi-annual party to celebrate the semester’s accomplishments
Intra-Lab Shut the Sash Competition (Gilly, 2015)

9. Additional Methods
Certain fume hood models are more energy efficient than others
Could require removal or replacement of current fume hoods, therefore an expensive option. To do so: (Earl Wall Associates, n.a.)
Apply “Right-Sizing” techniques
Use “Life cycle cost analysis” to advance fiscally sound decisions
Select the right hood for the right application. advantage of the many different types of hoods; even in the same facility
Make sure they work in tandem with the building mechanical systems to arrive at the most energy efficient health & safety design solution
In conclusion, Monthly feedback is an effective tool for encouraging better hood use behavior. However, potential savings from even large behavior changes can be limited if existing equipment is relatively efficient, so conservation programs should be tailored to the existing conditions.
