Help SLC Stay Cool this Summer

by SLCgreen outreach coordinator Stephan Sveshnikov

With much of the West seeing record temperatures this summer and 98% of Utah in an extreme drought, it’s a good time to remind ourselves of what we can do to keep our city a little bit cooler and ourselves safe.

While you’ve heard a lot of discussion about saving water during this drought, today we also want to talk about reducing the urban heat island effect— which helps save water, reduce ambient temperatures, and support a healthier ecosystem.

What is an Urban Heat Island?

Cities are always hotter than the average surrounding temperature because of what’s called the “Urban Heat Island” effect. Because the concrete, black asphalt, and black roof shingle material absorbs extra heat and releases it, city temperatures can rise by as much as 18 degrees Fahrenheit compared to the surrounding area on a cloudless day! This, in turn, raises the energy consumption of the city, because our air conditioners have to work harder to keep us cool. 

How can I reduce my home energy consumption during the summer?

What can you do to reduce the Urban Heat Island effect at your home or business?

First start with your own building. Saving energy means you’ll be more comfortable, save money, and reduce the ambient heat going into the neighborhood.

  • Cover your windows! When it’s hot, about 76 percent of sunlight on windows enters in the form of heat, according to the Department of Energy. Keeping blinds closed on the sunny side of the house or installing solar screens will keep your house from heating up as much.
  • Set the AC ten degrees higher if you’ll be gone from home all day, and set it at 78 degrees F or warmer if you are home. Cool off with cold drinks, a trip to the mountains, or turn on a fan to circulate air in the room you’ll be in.
  • Avoid using your stove and oven during the hottest parts of the day. 
  • Energy efficient evaporative coolers (also called “swamp” coolers) are perfectly-suited to Utah’s arid desert climate and can cut cooling costs by 75% compared to a central AC! 
  • Plant shade trees around your home. The more shade around your house, the less it will absorb direct heat from the sun, and the less your AC or swamp cooler has to work. 
  • Insulate! Make sure you have the appropriate level of insulation in your home. Insulation helps keep your house warm in the winter, but it also helps keep it cool in the summer, because the fewer leaks you have, the less that cold air you’ve worked so hard for can escape.

SLC Budget Prioritizes Maintaining High Standard of Service, Providing Equitable and Sustainable Opportunities

Salt Lake City Mayor Mendenhall’s new 2021-2022 city budget emphasizes financial stability for Salt Lake City, as well as “opportunities for an abundant, transformational, equitable future for all the city’s communities.”

The $350 million budget allocates funds to numerous initiatives and programs that will help Salt Lake City implement recommendations from the Commission on Racial Equity in Policing as well as expanding support for affordable housing. Salt Lake City will continue to prioritize building a sustainable and resilient city for all residents.

Due to the COVID-19 pandemic, residents have had unprecedented access to local government, connecting with departments more than ever. As SLCgreen moves into the new fiscal year, which begins July 1, we aim to build from this access, inviting more of our community into the decision making process, and working with the community towards greater sustainability and resiliency for all.

The newly approved budget allows Salt Lake City to continue to invest in critical public services, renewable energy projects, air quality, food access, climate equity, and more, which are described below.

Waste and Recycling Rate Increase

The adopted budget contains a rate increase on garbage containers. As you may recall, the Sustainability Department undertook a large public engagement process in late 2019/early 2020 to evaluate residents’ satisfaction with our waste & recycling services, and to seek feedback on how they’d like to see future rate increases occur.

While we do not take lightly the fact that rate increases impact everyone– and some more than others– we want you to know that we have worked hard for years cutting costs and streamlining our operations to forestall the need for a rate increase. However, it has been nearly seven years since we last raised rates. In that time, the cost of doing business has increased– impacting everything from purchasing and maintaining our refuse vehicles, to disposing of garbage at the landfill, to keeping up with the cost of living. For a couple of years, there were also fees associated with processing the City’s recyclables. (So far in 2021, we have begun to make money again on recycling which is great news. We are committed to maintaining a robust program through the ups and downs of the recycling commodity market).

You can visit this page to learn more about the rate increases, the survey, and what to expect. As always, if you have questions or comments, don’t hesitate to reach out to us at slcgreen@slcgov.com

Projects on Energy, Food, Air Quality & More

In our policy division, we are moving forward with some impactful and important projects. Here’s a closer look at some of what’s in store for the Sustainability Department’s Energy & Environment Division:

  • Advancing Salt Lake City’s Community Renewable Energy Goals

The Community Renewable Energy Program (C-REP), empowered by the Community Renewable Energy Act, H.B. 411, will help Salt Lake City reach its goal of community-wide net-100% renewable electricity. In 2022, Salt Lake City will work with other participating communities to bring Salt Lake City closer to its goal of 100% renewable electricity for the whole community.

2020 Year In Review

Happy New Year!

2021 is here! SLCgreen is excited to move forward. But as we prepare for the year to come, we’re also ready to incorporate what we’ve learned from 2020.

At the beginning of 2020, SLCgreen was eagerly preparing for a new administration and planning for a year of innovative sustainability projects. After a busy 2019 we were ready to take the next steps towards bringing net-100% renewable energy to our community. A new state-of-the-art recycling facility was near completion. And an innovative resident-led food equity program was convening to help improve food access in Salt Lake City. 

The challenges of the past year have been harrowing. Within the first months of 2020, Salt Lake City pivoted our work to respond to the COVID-19 pandemic. We experienced an earthquake that damaged our homes and businesses. Hurricane-force winds toppled thousands of trees and left many members of our communities without power for several days.  

Despite it all, SLCgreen was able to accomplish many of our goals with the help of our dedicated crews and community members. The challenges our community faced in 2020 laid bare the deep connections between equity, resiliency, and  climate action. The year required us take more direct actions to improve our emergency response plans, to better support the voices of residents who have been excluded in the past, and to expand our communications to facilitate more collaborative work.  

SLCgreen is ready to build off of what we learned during the past year, but before we set our sights on 2021, here are a few highlights from 2020.

Building a Clean Energy Community

In 2019, Salt Lake City set an ambitious goal of reaching 100% renewable electricity by 2030. Transitioning to clean energy will help the City reduce its carbon footprint and build more climate resilient communities. Last week, Salt Lake City took an exciting step towards reaching our climate goals.

The Utah Public Services Commission recently approved an application that allows Rocky Mountain Power to purchase the output from a large new solar farm to be built in Tooele County, Utah, on behalf of six large customers, including Salt Lake City Corp. This solar project, which will be among Rocky Mountain Power’s largest, will provide renewable energy to Salt Lake City Corporation, Park City, Summit County, Utah Valley University, Park City Mountain and Deer Valley ski resorts.

For Salt Lake City, this project will help meet nearly 90% of the City’s municipal electricity needs by 2023.

This means that Salt Lake City’s government buildings and operations will primarily source its electricity from renewable energy. This substantial shift to renewable energy is projected to increase in the city’s electric bill by less than 2%.

Next Steps Towards Community-Wide Renewable Energy

Moving Salt Lake City’s internal electric consumption to renewable energy is a first step towards community-wide renewable energy. In 2019, the Utah State legislature passed HB411, the Community Renewable Energy Act. This law establishes a legal pathway for communities serviced by Rocky Mountain Power to create a net-100% renewable electricity portfolio.

Staying Cool this Summer and as the Climate Warms

Photo of Salt Lake City looking towards east-bench foothills on sunny day.
Summer in Salt Lake City can be beautiful, but rising temperatures make staying cool a challenge.

Staying cool during Utah summers is always difficult when the thermometer climbs above 90, 95, and 100 degrees Fahrenheit.

This year it’s even more challenging with the necessity of staying home, and the closures or limitation on public swimming pools, splash pads, and some cooling centers.

With more people spending more time at home, utility bills and household waste have spiked.

As the Natural Resource Defense Council (NRDC) points out, there are other ways to stay cool than by cranking up the A/C. Here are a few ideas that work especially well in our desert climate:

  • Stay Hydrated! Staying hydrated will help you stay cool and healthy, even when it’s hot! Read more about the signs of dehydration here.
  • Use your windows! Windows can be your best friend. Try to open things up at night to help cool your space down, but close the blinds or use window coverings when it starts to get hot our during the day.
  • Fans: Be strategic about box fans or overhead fans – they can help keep things cool and reduce the need for AC. But save energy by turning them off before you leave the house!
  • Optimize Space: Keep doors shut to areas you’re not using – that way you’ll be cooling a smaller space, which is more energy efficient!
  • Cook Carefully: Opting for recipes that don’t use the oven or require a long time on the stove will help keep your kitchen cooler – and may even help with your indoor air quality.
  • Switch to LED lights: Using more efficient lighting will help you save energy and money. LEDs, and other home energy efficiency improvements, can help you cut your energy bills and keep space cooler. Typical incandescent lights also put off more heat, so switching to LED reduces the heat burden in your home.

Lights Off for Daylight Hour 2020

The summer solstice is the day of the year when due to the earth’s position on its axis and rotation, the hemisphere is exposed to the most sun throughout the day. In the Northern Hemisphere, the longest day of the year falls around June 21, marking the arrival of summer.

Traditionally, the solstice has been celebrated by many cultures as the start of the harvest season, using the extra hours of daylight for summer festivities. This year, you can honor the solstice by saving energy through participating in Daylight Hour on Monday, June 22!

– – – – –

The Engineering News Record (ENR) chose Salt Lake City’s Fire Station 14 as their “Best of the Best Project” in the national Government/Public Building category. This is the seventh award for Utah’s first Net Zero energy fire station which was built in 2018.

The latest award, which is detailed in the March 23 issue of ENR, is the culmination of a year-long process during which construction experts from ten different regions selected finalists. Those 200 finalists then moved to the national competition and were vetted by a different panel of judges.

Fire Station 14 is believed to be not only Utah’s, but the nation’s, first Net Zero energy fire station. That means it produces as much energy as it consumes on an annual basis.

It’s also expected to become certified as LEED Gold, showing it meets a range of holistic sustainability benchmarks, including material management, waste diversion, water conservation, energy efficiency, renewable energy, and more.

The project was recognized last year as the Best Government/Public Building for the Mountain States Region. As a result, it was automatically entered into ENR’s national “Best of the Best” Competition. Representatives from Zwick, the general contractor, anticipate accepting the award as a representation of the collaboration between the architects, Blalock & Partners, Salt Lake City (Engineering/Fire Dept.), and themselves.

Fire Station 14, near California Ave. and 3800 West, and Fire Station 3, in Sugar House, are both Net Zero and were opened within months of each other in 2018.

Electric Vehicle Usage Increasing in Salt Lake City

Transportation accounts for nearly 50% of the pollutants that accumulate during inversions. Reducing emissions from cars is a great way to protect our air. Electrified transportation is a step towards cleaner air, healthier communities, and a stronger economy.

Graphic depicts air pollution statistics on orange clouds. Text reads: 
"Percent pollution reduced by an EV along the Wasatch Front. 57% PM10, 81% PM2.5, 98% SOx, 90% NOx, 99% CO, 99% VOC."
Electric Vehicles can significantly reduce air pollution.

EVs in Salt Lake City

Luckily, more and more Utahns are investing in electric vehicles (EV). Based on the number of unique charging sessions at Salt Lake City Corporation’s 36 Level 2 public EV stations (not including those at the Airport), there has been an exciting uptick in EV use in Salt Lake City.

In 2019, there were 21,371 unique charging sessions (meaning a car charged for longer than 5 minutes) at Salt Lake City public stations, compared to 12,870 in 2018.

Salt Lake City is following the national trend of growing EV use. According to the Edison Electric Institute, there are close to 1.5 million EVs being driven in the U.S. as of December 2019. Utah has seen its share grow to approximately 2% of total vehicles now comprised of electric, plug-in electric, or hybrid vehicles, and we want to continue pushing that number higher.

With EVs becoming more popular, Salt Lake City is working to strengthen the City’s EV infrastructure. In 2018, SLCgreen and Utah Clean Energy created the Electric Transportation Roadmap. Since then, Salt Lake City has installed 36 Level 2 charging stations at sites around the city, plus over a dozen at the Airport. These stations are free to use for 2 to 4 hours depending on the station.

Support Fellow EV Drivers: Don’t Hog the Charging Stations

Salt Lake City is pleased to see that charging sessions have increased significantly since the stations were initially installed. Up until now, Salt Lake City has not had to enforce the charging time limit. However, because more people are using the stations, drivers need to be mindful of their fellow EV users and respect the time limit.

In 2017, 1,500 sessions exceeded the time limit. That number has grown to 4,600 in 2019. While these only represent a small portion of the total charging sessions (80% of sessions were within the limit), it is still an inconvenience for other drivers who may need to fuel up.

Graphic shows graph of how many sessions exceed posted time limit.

Due to the growing demand for charging stations, the time limits will be actively enforced beginning March 9. Please be courteous to your fellow EV drivers and be mindful of the time limit. Drivers who exceed the posted time limit may be ticketed $75.

Vehicle charging usage may be monitored via the ChargePoint cloud system to determine if a vehicle has overstayed the posted parking time limit.

The public may also report potential EV stall overstays to the Compliance main line at 801-535-6628.

Clean Machines

Although electric cars still rely on electricity which is not (yet) wholly derived from renewable resources, they are still cleaner than gas-powered cars. According to the Union of Concerned Scientists, the average gasoline-only car produces 381 grams of CO2e per mile, while the plug-in hybrid produces only 191 grams and a battery EV produces only 123.

Graphic compares average CO2 emissions of gas-powered, plug-in hybrid, and battery electric vehicles. Stats are described in above paragraph.
