Climatic Zones for Building Codes
“Why are climatic zones important for building codes?”
Building codes such as California’s Title 24 are vital for regulating the energy, ventilation, and material needs of the built environment. However, these things are dependent on the external environmental conditions. Buildings codes that would work for the Bangladeshi jungle may not be suitable for the Yukon mountains. As such, separate Climatic Zones may be defined in building codes that adjust the parameter requirements. This is why Climatic Zones for Building Codes are important.

Why Rising Global Temperatures May Impact School Performance (And Why This Is an Equity Issue)
“Why may rising global temperatures impact school performance and why is this an equity issue?”
Working in hot conditions is always difficult. It makes it hard to concentrate, you need to take more water breaks, and the experience is just generally unpleasant. Studying and learning in a classroom is no different. Schools with less adequate resources are overwhelmingly more likely to have less-maintained and up-to-date facilities that lack air-conditioning systems. With the advent of climate change, temperatures are going to become much higher, and communities who do not have the resources to cope with this are going to be impacted more. This is Why Rising Global Temperatures May Impact School Performance (And Why This Is an Equity Issue).

How Stricter Building Codes Can Drive New Markets
“How can enforcing stricter building codes open up new markets?”
When building codes become stricter, many housing units will need retrofits or new appliances will need to be made. This can induce demand for a product and in effect open up new markets. For example, by requiring new residential buildings to have tighter wire meshes, these new models will become a hot commodity. This is How Stricter Building Codes Can Drive New Markets.
MERV 8 Filters
“What is the most common of all the air filter types?”
Air filters come in many different shapes and sizes. However, the most common type of air filters has to be MERV 8 Filters due to their mandatory inclusion by the policy of many U.S States.

Why Urban Heat Resilience Needs to Be Equitable
“Why must equity take paramount importance when we design urban heat resilience?”
With the increase in average global temperatures and the densification of metropolitan centers, urban heat resilience will become a greater issue for the world. However, engineers and urban planners must keep in mind that the most vulnerable people in society, particularly seniors, young children, pregnant women, and people with disabilities and medical conditions will be the most susceptible to extreme heat. Resilience techniques that do not take these elements of society into account or ignore their needs will actively hurt them. For example, if all of the resources go to greening the wealthy districts of a city, then none will be left for people of lower-income areas. Since it is the duty of resilience professionals to ensure the safety of those most affected by climate change, it is only understandable Why Urban Heat Resilience Needs to Be Equitable.
Indoor Air Quality
“What exactly is indoor air quality?”
When air quality is talked about, usually the discussion is focused on the exterior environment. However, the air quality inside a building can fluctuate as well. The Indoor Air Quality, also known as IAQ, is contingent upon a multitude of factors, such as type of ventilation, exterior air quality, processes occurring inside the building, and building materials. IAQ can have drastic effects on its inhabitants.
“How can we circulate air from the inside of an interior environment instead of the outside?”
Most HVAC systems rely on using external air as a supply. However, sometimes the ambient air is too polluted or hot for practical use. To work around this, we can use air from the interior environment as the feedstock. This Air Recirculation is very useful in Summer months when temperatures are much higher and air quality is much lower.
How Extreme Weather Events Can Cause Energy Prices to Skyrocket
“How can extreme weather events cause energy prices to go out of whack?”
When the weather gets too hot or too cold, people will turn on HVAC systems to compensate. This will cause greater demand on the electricity system, which in turn will lead to more constraints and therefore higher costs for everyone. This is How Extreme Weather Events Can Cause Energy Prices to Skyrocket. The advent of climate change will only exacerbate this, as extreme weather events will become far more frequent. So in the end, it will pay in the long term to upgrade critical infrastructure systems to more resilient standards.

“How can we make a building that uses no energy?”
Net zero energy usage in buildings can mean two things. Either all of the energy consumed by the building is met through self-generation or the building itself uses no energy! The latter is the foundational idea behind Passive Buildings. Passive buildings are edifices that obtain all of their heating and lighting through natural means. This means that such buildings have lots of large windows to let natural sunlight in, are superinsulated, and employ passive solar design. Therefore, these buildings can skip the need for complex lighting and HVAC. Passive buildings are amazing to experience and should be enjoyed by everyone in my opinion.
