Air infiltration (air that comes in) and air leakage (air that goes out) negatively impact energy usage and costs in conditioned spaces – for homes and businesses alike. We’ve talked about what infiltration and leakage are and how to combat them at a basic level, but to really fix the problem for...
In this blog, we will discuss air infiltration and leakage, what they are, how they can impact energy costs and simple steps that home and business owners can take to reduce excess costs brought on by air infiltration and leakage.
An EDT Case Study regarding issues pertaining to drywall within a residence under construction during a stormy and cold fall season. Was it due to the storm or power outage? Or was it just inadequate surface preparation of the drywall by the contractors? And what are the industry-wide recommended...
Hurricanes are somewhat unique in that they generate multiple types of forces that can affect coastal properties. This blog discusses how EDT determines the cause of damage based on hurricane wind and water forces.
After a fire involving a building or industrial structure, there are often multiple types of damage to the building materials. Knowing how heat affects various building materials can be helpful in determining the level of damage to building components.
In Part II we discuss how using our Scanning Electron Microscope (SEM/EDS) helps answer important questions as to how a steel part harvested from the tongue of a failed trailer hitch broke, and what was the cause?
As you may recall, in parts one and two of the blog series we discussed several preventative steps you can take to extend the life of your HVAC system. But, there is one last and very important area to be checked on your HVAC system:::- the refrigerant charge.
For most of us, seasonal maintenance on our home’s HVAC system is not a priority. The majority of homeowners use their HVAC system until a component fails. Understanding the basics of how our home’s HVAC system functions can help us to prioritize our HVAC maintenance.
In our first post (part 1) we discussed equipment ratings and location definitions (what is a dry or wet location). In our last post (part 2) we discussed equipment that is not made to get wet, yet for some reason it does and what do you do. So, what happens when the Authority Having Jurisdiction...
In our last post we discussed equipment ratings and location definitions (what is a dry or wet location). In this post let's discuss equipment that is not made to get wet, yet for some reason it does. Does this mean it needs to be thrown away and a new one purchased? No, of course not.
It has been common in the past to assume that water and electrical equipment do not mix. However, just because a piece of electrical equipment, such as an electrical panel or a computer, gets wet doesn't mean that it needs to be replaced.
Beyond the obvious engineering applications or the occasional mention of a pizza or package delivery that most of us continually hear about, what sort of crazy, perhaps brilliant, drone applications have industrious problems solvers come up with? The following are three of my favorites.
To understand proper condensate removal, it is first important to have a working definition of the term condensate in the context of Heating, Ventilation, and Air Conditioning (HVAC). Most HVAC systems contain a form of refrigeration cycle which uses mechanical work acting on a fluid (in most cases...
Freshly fallen snow is often a beautiful and awe-inspiring sight to see. Some parts of the country may see new snow daily while other areas may only see it once a century. Regardless of how prepared our cities are, snow can have a great impact on our everyday lives, particularly on our structures...
Computer graphics are visual communication tools to aid an audience in visualizing data in a clear and interesting manner, compared to text or oral communication alone. Within this article are examples of how EDT uses Computer Graphics for Forensic Engineering purposes.
