I read through the article “Backdrafting” by Nick Gromicko and Kenton Shepard as it seemed a good fit for the coursework just completed. Great article that gets straight to the point of a very important safety topic. Important because if the environment is right for backdrafting to occur, combustion gases can be sucked back into the house and may potentially harm or kill building occupants. One of the first steps taken in a home inspection should be to go through the house to ensure that the house is “safe” for it’s occupants.
A baghouse is the generic name for an air filtration system in large commercial and industrial buildings . They play an important role to keep clean quality air for environmental standards.they basically consist of duct work a hopper with filter and some sort of air blower system.
Sealing air leaks can improve your home’s heating and cooling efficiency by 10% to 30%.Plumbing penetration under sinks and vent pipes through attics are one source of energy loss.Homeowners can mitigate these situations with some spray foam in a can.
While upgrading the thermostat that came with the house to a programmable digital thermostat, I noticed that wire holes were letting in air through the drywall. I was very surprised how much air was coming into the house through these small holes. I could actually detect the airflow with my fingers. I sealed them and wired the thermostat correctly the first time.
I bought fire extinguishers for my kitchen because a friend of mine as a teenager almost burned down his father’s house from a kitchen fire. Now the two extinguishers have been recalled in the last year and I got two newer models free as part of the recall. You should check yours if you have not, I believe it is the Kiddie Brand and they have a website to check if your model was recalled. It is quite difficult to see the model numbers.
The home energy blower door test costs about $450.00 for a typical house. This test includes a report of the air leakage locations and recommendations for the sealing approach. The report lists the sealing measures in a cost efficient priority.
A complete home energy audit is designed to identify problem areas in your home, whether they’re in the attic, basement, around windows and doors, or in your duct work. Once we know what is causing your home comfort problems, a solution can be recommend.
Happens that doing a home inspection yesterday that there was conditioned air exiting the receptacles in the garage. Meaning that the conditioned air is entering the wall cavity and then through the box in the garage. Recommend sealing all outlets and penetrations on this wall.
Energy star program criticized in the article library was an interesting read. I learned that it may not necessarily be energy efficient as many fictitious numbers easily make it to certified. Also, i learned that some companies have been given the right to download and use the logo even on items that do not qualify.
Perhaps the question is off topic, but I would like to know if someone had to deal with programming the room thermostat Fantini Cosmi (any model)? I want to provide energy savings by reducing the temperature for a period of people’s absence in the room for up to several months. On this website, I found some assignments similar to this question, but maybe just someone has already done such an operation and can tell in detail what to do. Thanks!
This is a picture of an energy audit taking place in the summer utilizing the blower door system to draw air into the house to better identify areas of infiltration. This is the ideal way to utilize the Ir Camran during the energy audit testing as putting the house under pressure will lesson the effectiveness of the camra
With the current program/training by internachi it is possible to provide a basic home energy audit by utilizing the homes own systems to put the house in a negative pressure situation. It is key however that if you are unable to provide a true blower door test that in your communication with your client that it is understood the scope that your audit will entail I have personally tried to find a location that rents/lease blower doors as I currently do not have the funds to put 3k towards my own at the moment and am unsure as to the current demand within my area.
Here is a picture of a vent pipe going through a top plate of a wall that is pushing out on the drywall and is not sealed. The pipe should be sealed to the top plate at the drywall should be sealed allso.
This is a picture of the attic access. After inspecting this access cover there was no insulation or weather stripping on the backside. Lots of energy is being wasted. I suggested to add insulation and weather stripping on the attic facing side.
The article I chose to read and learn about was on “Cool” energy efficient roofs. I learned that cool roofs offer benefits such as increased lifetime of roofing materials and that they save energy. Also, some utilities might offer rebates for going with a cool roof system.
this picture is a picture of a basement ceiling. I chose this picture because I am calculating cubic feet in a house and I need to determine if the basement is a conditioned space or an unconditioned space. This basement is a conditioned space as there is insulation on the walls.
The picture i chose is the attic access picture. I chose those picture because I noticed that the attic access hatch/opening to this house had an air leak. I noticed the air leak with my infrared camera. I made a note in my report to the customer that an adhesive strip where the access hatch and the frame for the access hatch meet would make a significant difference in the air leak issue
As you can see in this infrared photo of these recessed can lights there substantial air leaks around the fixtures. This could adversely affect heating and cooling costs and can contribute to poor air quality in the home. There are numerous was you could seal the can lights, one of them being the use of a top hat and expanding foam insulation.
In this article I read about Blower Door Testing I learned that the technology was developed in the 1970’s as a research tool. As the technology has evolved it has allowed for the development of more portable equipment. This and reduced weight of the equipment has led to the standard use of the blower door as a part of energy audits.
