As great as a product as asphalt is, there’s no doubt that there is room for improvement. Scientists all over the world are trying to solve its most common issues, such as potholes, cracking, ice build-up, and storm water drainage. Los Angeles is now tackling another issue with the material: heat island effect.
One of the hottest parts of the Los Angeles area is Canoga Park, located in the San Fernando Valley. For that reason, the LA city officials are testing out a “cool pavement” coating to hopefully reduce the increased temperatures that asphalt causes.
10,000 square feet of a street in the area was coated with a paint-like material called CoolSeal, made by a company called GuardTop. Although the product is applied like paint, it’s actually an asphalt-based sealcoat.
Gregg Spotts, assistant director of L.A.’s Bureau of Street Services told ABC7 that the coating has dropped pavement temperatures 11-13 degrees versus adjacent pavement that has not been coated.
The coating is placed in two layers, with each layer being 15 microns thick. Spotts said that the first coat only took an hour for the first coat to dry.
15 streets across the city will have the material applied to it over time. Total project cost for all 15 roads is estimated to cost around $150,000.
While it’s scientifically proven that lighter colors reduce temperatures, lighter colors also greatly increases the glare, which will make sunglasses even more important in sunny California. I’m also curious to know how quickly the product loses efficiency as it gets dirtier from dirt and tires. To keep the surface lighter, consistent maintenance will become more important.
Nearby residents are hoping that the cooler temperatures help keep their energy costs down.
I’ve been very fortunate over the course of my relatively short career in construction to spend time focusing on many different aspects of construction. I recently spent about two and a half years working in site development and Storm Water Pollution Prevention Plan (SWPPP) compliance on a national scale and I wanted to share some of the insights that I gained from that experience.
In 2016, Elon Musk and Tesla announced that they had developed an innovative solar roofing tile that looks almost identical to traditional roof shingles currently on the market. Standard solar panels look be large and clunky on a roof, which made many excited about a nearly “invisible” solar tile option. After 3 years, we recently got a major update into how the installations of the product is going.
On Thursday, April 18th, the New York City Council passed what they are calling “NYC’s Green New Deal,” which legislators hope will greatly reduce the city’s greenhouse gas emissions. In order to achieve those results, several mandates included in the legislation will have major effects on the construction and real estate industries.
Almost 7 years ago, construction began on the west side of Manhattan’s $20 billion mixed-use development. On March 15, 2019, Hudson Yards, as the development is known, has officially opened.
Mercedes-Benz Stadium, home to the NFL’s Atlanta Falcons, was completed in late 2017. The impressive structure had a hefty price tag of $1.4 billion, but it has already played host to several of the biggest events in sports, including the 2018 College Football National Championship and the recent 2019 NFL Superbowl. In addition to playing a large role in the sports world, it’s also playing a large role environmentally for the area surrounding the stadium.
A new 21-story apartment building proposed for Milwaukee, Wisconsin as received unanimous approval from the City Plan Commission. If built, the new tower could possibly be North America’s tallest mass timber building.
The USGBC recently released their 2018 ranking of the Top 10 US States for LEED construction, which is sorted by Gross Square Footage per Capita. That ranking system allows them to get a fair comparison of states, despite differences in population and number of buildings.
Tall buildings made with structural timber have been on the rise in Canada and European countries in recent years, but the United States has been slower to adopt the method due to code restrictions. The state of Oregon recently released an addendum to their building code to allow taller mass timber buildings in the state and an upcoming International Code Council (ICC) vote could encourage more states to follow suit.
You may have been sitting in your house or office one day and noticed the distinct sound of a bird hitting the window. It’s pretty common, as it’s estimated that as many as 988 million birds die in the US each year by colliding into glass. The new arena that will house the NBA’s Milwaukee Bucks has incorporated some design elements that will reduce the amount of birds killed by the massive structure, allowing it to be dubbed the “World’s Most Bird Friendly Sports Arena.”
