Do You Know How Smart Our City Is Becoming?

Washington, D.C. is full of smart technologies, some of which you know about (apps such as Uber, Lyft, Google Maps, Bikeshare, etc.) and others you probably don’t. This past summer, I attended an event called Smart City Symposium- “Solutions for Business Growth and Economic Development” (include a small exhibition) in downtown D.C., hosted by the DC Chamber of Commerce and Verizon.

The Office of the Chief Technology Officer shared some of the technologies the city is already using. Further information on this can be found on their website.

But “5G Technology” was the key word through the whole event. For people who don’t know about 5G, it is basically 4G with user data. For example, Google will detect the amount of traffic by counting how many people are using their map at a specific location, same as they are tracking the restaurant rush hour by counting how many people are searching for it online.

Verizon is working to engage 5G technology in the D.C. area to make people’s lives more convenient. Here are some of the great products they demonstrated:

  1. Smart trash can

I was really impressed by this new trash can. They look like unimpressive boxes, but can fit four times more than a regular trash can. The smart part is that it can sense how full the trash bin is in real time and send a signal that it needs to be emptied, allowing garbage crews to come only as needed instead of on a set schedule, emptying bins that are not yet full. It can save time, resources, and energy emissions.

2. Home clinic

Home clinics are long-distance personal doctors. A doctor can talk with patients over video chat and then send devices the patient can use to measure their own vitals, such as blood pressure or blood sugar. After they know the patient’s health information, they can provide suggestions and prescribe medication. This will save patients time and money by allowing them to skip a trip to the doctor’s office if they have only minor symptoms and don’t need to go to hospital. The same methods can be used for other doctors, such as psychologists.

3. Agriculture drone

Agriculture uses more natural resources and has a greater carbon footprint than almost any other sector. Agricultural drones, however, will change the way crops are produced. Drones will gather information throughout the day on weather conditions like temperature, moisture, and wind. As more information is collected, the system will analyze the data and tell other devices how much water different crops need, if a certain action needs to be taken, and so on. This will significantly reduce resource waste and improve production.

4. Smart car

This program is similar to Zipcar, but it’s currently only implemented on some university campuses. It works like Car2go, where the customer can use the app to track where there has an available car. However, Verizon is still testing this technology so I do not have too much information about it.

From what I can see, 5G technology will save people time and help make life easier and more convenient. One of the downsides, however, is that I feel less secure because our personal information is publicized and stored on the internet. The internet will have information on where we are, what we are doing, and what we are talking about. I am excited about how the world is becoming more and more advanced, but I also want to be reassured that our information can be private. This is something people should keep in mind as these types of technologies become more prominent.

A Little LEED Strategy for buying home

Home_LEED

Recently I’ve been studying for LEED Green Associate exam and the word “density” has been hanging in my mind, this is because “density” this word throughout the whole book. The very beginning of a project is ‘Location and Transportation’. This is a new category that was added to the LEED rating system. This category put more emphasis and attention on reducing one of the main contributors to global warming: transportation. It is clarified through the ideas of reducing the cost, pollution, and depletion of resources related to the daily transportation of people and goods to and from a destination. After reading Veronica’s post last week, it got me thinking about sustainability and how it applies to our daily lives, especially in choosing where to live. I think that LEED principles can be applied to a housing search.

The book divided Location and Transportation (LT) category into 4 points: Location, Transportation, Site Development, and Health and Livability. These points are often similar to what people consider when looking for a house or place to live.

Location:

Locate within a LEED-Certified Neighborhood Development

A LEED-Certified Neighborhood usually is a sustainable site. This is because the neighborhood has to meet the qualification of LEED requirements such as walkability, green infrastructure, floodplain avoidance, etc.

Located within proximity of surrounding density and diverse uses

“Density” is an important word in LEED. The reason behind this is to cut the distance shorter for people to travel to work or visit the building. Also, if the building is within walking distance (0.5 mile), people will not need to drive. Both ways would cut down on greenhouse gas emissions and will help reduce global warming.

 

Transportation:

Limit available parking

LEED-Certified buildings usually have limited parking, because this can encourage people to carpool or use alternative ways of travel.

Develop in areas that have multimodal transportation access

This could also inspire people to take public transportation modes like bus or rail.

Site development 

(This point is more for a someone building a home and their location selection)

Avoid developing on environmentally-sensitive land

This is for the sustainability environment. Considering the local bioregion, watershed, and community can help a project team minimize the sustainable features of the surrounding environment and to climate change. In LT category, sensitive land defines as farmland, floodplains, threatened or endangered species habitats, water bodies, and wetlands.

Locate the project on a pre-developed site

It would be an ideal area, because of the preexisting infrastructure is already in place. Pre-developed location can reduce the cost of installing new roads, sewer, and power lines.

Locate the project on a high-priority site such as a brownfield

A brownfield is a property that has the presence of hazardous materials, pollutants, or contaminant that may affect by redevelopment if the property. Remediation and development of brownfield can avoid land waste and reduce urban sprawl.

 

Health and livability

Develop in areas that promote walkability

Sidewalk and shelter for pedestrians should be provided, these make it easy for people to walk to and from the building for basic needs and routine functions.

Provide bicycle storage facilities, shower room, and bicycle networks in close proximity to diverse uses

This encourages the use of non-motorized modes of transportation.

Provide a bicycle maintenance program for employees or bicycle route assistance for employees and customers.

This could encourage people to ride bikes, walk, or run errands during the day. This can also decrease greenhouse emission caused by vehicle use and increase the health and welfare if building occupants.

 

Other factors recommended that contribute to this field that speak to “density” are the following:

Provide pedestrian amenities

Promote connectivity

Create a diverse community

Promote access to sustainable food

Provide access to grocery stores.

 

All of these factors would reduce a number of people who use their cars in their everyday lives. This will help contributing less greenhouse emission, at the same time, provide human more options to work out and revitalized neighborhoods.

Hope these points can help you, and Veronica, with your home location selection.

What’s on the Inside Counts Too!

Environmental Justice issues are not limited to pollution outside. 

In the world of environmental justice (EJ), there are many articles and discussions around the impacts from pollution that occur outdoors – industrial pollution, contaminated water bodies, mobile emissions, and other air quality impacts; however, many low income, minority communities often suffer from residential exposure to harmful contaminants that either occur indoors or infiltrate from outdoors. Let’s examine a few articles that have covered this topic.

In Moving Environmental Justice Indoors: Understanding Structural Influences on Residential Exposure Patterns in Low-Income Communities, which was published in the American Journal of Public Health in 2011, the authors explore disparities in indoor residential environmental quality. Below are some pertinent observations/ conclusions based on their research:

  • People in low income communities are more likely to live closer to mobile and stationary sources of pollution which increases the chance of outdoor pollution infiltrating indoors
    • Low income homes are often older and not as structurally sound (having holes). This may lead to increased infiltration from outdoors.
  • Homes within low income communities are more likely to have peeling paint which is a predictor of lead exposure in older homes; water leaks which are a predictor of mold and moisture development; and structural issues that serve as entry points for cockroaches and other pests
  • Communities with low socioeconomic status are more likely to experience second hand smoke particularly people who live within older multifamily buildings because the air infiltrates from unit to unit
  • One study has shown that lead concentrations in household dust, associations were found with income, race/ethnicity, floor surface or condition, and year of construction
  • Residential infestation of pests is linked to low socioeconomic status
  • Residential exposure to pesticides is more prominent in low income communities due to infestation

This research study explores several angles of exposure to indoor environmental justice issues each can be explored further as stand-alone research to further validate the connections between low socioeconomic status and EJ.

 

The Boston Globe published in article in April 2016 reporting Low Income, minority areas seen as lead poisoning hot spots. While this article is focused on Massachusetts this may be reflective of issues within your community as well. Here are a few findings as revealed within this article:

  • Cases where children have harmful levels of lead in their blood are predominantly in low income and minority communities
  • Boston has a citywide rate of lead poisoning at 2.8% but pockets within Dorchester (an overwhelmingly African American neighborhood) have rates over 6%
  • The article quotes Robert Knorr, the Director of Environmental Epidemiology at the Massachusetts Department of Public Health’s Bureau of Health as stating “Being poor and being a minority not only increases the risk of blood lead poisoning but makes it difficult to find a safe home”
  • Massachusetts has the second oldest housing stock in the country. Children living in these homes are primarily low income and minorities.

This news article in the Boston Globe is hyper focused on Massachusetts; however, it further validates the impact of indoor environmental issues concentrated in marginalized communities.

In an article entitled Homes of low-income minority families with asthmatic children have increased condition issues published in the Allergy and Asthma Proceedings, the correlation between home maintenance issues in low income minority communities and the prevalence of asthma in children is explored. Below are some discussion points and findings from the article:

  • Reviewing the occurrences of asthma in urban and rural communities shows that there is a socioeconomic difference that affects access to and quality of health care
  • Housing that is subpar and indoor environmental exposures have been correlated with increased indoor allergen exposure and sensitization and greater asthma diseases and death for low-income, minority children living in urban areas
  • This subpar housing usually has cracks that allow pests such as bugs and rodents to enter the home such as cockroaches, which can trigger asthma and allergies
  • Poor ventilation allows for high concentrations of allergens, tobacco smoke, CO2, radon and VOCs
  • In this study, homes of Latino children had the highest number of maintenance concerns followed by homes of black children and then homes of non-Latino white children
  • The study concluded that asthmatic children from low income black and Latino families had more areas of home and safety and maintenance concerns than non-Latino whites recruited from the same region
  • This article purports that improving living conditions in cities offers great promise for reducing health disparities and improving the quality of life and well being of children

This article focuses specifically on asthma but does point out that both children and adults who live in substandard housing face a host of health issues but lack adequate access to health care. Children living in inadequate housing are particularly vulnerable to asthma because of the identified maintenance concerns. The study focused on a small concentration of homes so it would be great to see this broadened across the United States.

Unfortunately, low income and minority communities face health risks linked to outdoor environmental justice issues but this is compounded by the fact that they often live in substandard housing which puts them at risk inside their home. Advocacy to eradicate environmental inequities must go beyond fighting industrial sources of pollution to advocating for adequate housing that is properly maintained for all.
