Why Building Codes Should Incorporate Future Temperature Projections
“Why should building codes incorporate future temperature projections?”
Building codes often take into account local temperatures in their guidance. For example, California’s Title 24 building energy efficiency codes require residential units to have minimum ceiling and wall insulation values corresponding to their local climate zone. With the advent of climate change, the temperatures in such climate zones will shift, and the buildings built today must withstand this new paradigm. To illustrate, the Californian city of Fresno is projected to experience 10 times as many heat days per year between 2050 and 2099 than what it experienced from 1961 to 2005. Policymakers should start considering Why Building Codes Should Incorporate Future Temperature Projections to protect their citizens.
How Rainwater May Become Too Contaminated for Drinking
“How may rainwater become too contaminated for drinking?”
Catching rainwater for later use is a commonly proposed solution for drought adaptation. But when adopting these systems, health and safety risks need to be understood. Contaminants such as viruses,, parasites, bacteria, and dust and smoke particles may find their way into the rainwater. If the rainwater is contained in an open roof system, then it can be exposed to bird waste and insects. An older building may have materials such as asbestos and lead that can poison the water. These are all reasons why adaptation planners will need to consider How Rainwater May Become Too Contaminated for Drinking.
How Storms Can Overwhelm Water Treatment Systems
“How can storms overwhelm water treatment systems?”
Sewage water treatment systems are designed to channel a certain amount of water. However, when storms happen, a gush of water can flood these sewage systems. If too much volume seeps in, then the system can become overwhelmed and spill out. This can lead to discharges which can pollute nearby streets and bodies of water. Holidays are especially strenuous since wastewater systems are operating far beyond average use. This is How Storms Can Overwhelm Water Treatment Systems.
Why Heavy Storm Water Can Damage Transmission Lines
“Why can heavy storm water damage transmission lines?”
Electrical transmission lines typically have water-resistant polymers coating their cables to protect them from water damage. But during heavy rain storms, some water may get through and enter. The presence of moisture can heavily speed up the current in the circuit, blowing the fuse and destroying current flow. If the grid system does not have sufficient redundancy, outages can ensure. This is Why Heavy Storm Water Can Damage Transmission Lines.
The U.S Federal Adaptation and Resilience Group
“What is the current working group leading federal adaptation synergy in the U.S.?”
On December 8th, 2021, U.S. President Biden signed Executive Order 14057 to catalyze environmental initiatives by the Federal Government. One of the products of this order includes the launch of The U.S. Federal Adaptation and Resilience Group. This working group draws knowledge and expertise from the various U.S. federal agencies to address climate adaptation. Their current (as of writing) activities include discussing climate data for adaptation measures, modeling economic responses for adaptation, natural resource management, and fostering engagement between federal agencies.
Tax Funding for Metro Systems
“How can we use tax funding for metro systems?”
Metro systems need a revenue stream to operate. One avenue to accomplish this is to leverage a tax and use the money raised to contribute to funding. This is how Tax Funding for Metro Systems works.
The U.S Highway Trust Fund
“What funds federal highway and mass transit projects in the U.S.?”
The U.S. federal government funds highways and mass transit projects. But how exactly does it do this? Well, it leverages a tax on gasoline and diesel fuel to store into a fund called The U.S Highway Trust Fund. The highway trust fund is made up of two accounts, the highway account, and the mass transit account.
New Metro Train Car Design
“How do metro organizations design new transit cars?”
Metro organizations work on updating their transit cars when the time comes for it. The entire phase begins with New Metro Train Car Design. New cars are designed for system needs and capacities, looking over variables such as speed, aerodynamics, cost, and rail system. The design phase will set the tone for the rest of the project.
New Metro Train Car Testing
“How do metro organizations test new transit cars?”
The state of the art of metro cars advances each year. To keep up, metro transit organizations new to bring new train cars into their fleets. However, they must be tested to ensure they work as intended. This process can include wind tunnel testing, HVAC system checks, propulsion calibration, and more. New Metro Train Car Testing is a vital part of making transit systems as safe and efficient as possible.
