Tips On How To Do A Home Energy Inspection Using A Thermal Imaging Camera

With the growing concerns about global warming, more and more people are becoming aware of their responsibilities in addressing the issue. Organisations and individuals are now measuring their carbon foot prints and trying to reduce them to a lower value. One of the very basic step, for an individual, is to know how to do a home energy inspection using a thermal imaging camera.

Home energy inspection basically refers to an audit in the home to analyse the various heat flows in the house. Then, we calculate the energy conservation and define steps, processes or system to reduce the amount of input energy. The equipment such as blower doors and infra red cameras can be used to assess the energy efficiency of the house.

One of the crucial devices used for home energy thermal camera even for your iPhone inspection is the Thermal Imaging Camera which is also known as Thermographic camera. These types of cameras form an image using infrared radiations. This camera works on the principal that all objects emit a certain amount of black body radiation as a function of their temperatures. So if a body is at a higher temperature, it will emit for infrared radiations as a black body.

The thermographic cameras use a technique called density slicing where monochromatic images are displayed in pseudo colour so that human eyes are able to see intensity differences clearly. How to do a home energy inspection using a thermal imaging camera becomes fairly straightforward if we understand this principle.

The resolution of these cameras is fairly lower than normal optical cameras. In case of temperature measurement, the warmest part of the picture are coloured white, intermediate temperatures are red and yellow and the coolest part are blue. Normally a scale should be used to identify the temperature ranges.

While conducting an energy audit with a thermal imaging camera, the area and resistance to heat flow for various components is recorded. The leakage rate and air infiltration rate is then figured out. This exercise aims at quantifying the buildings overall thermal performance. The inspection also assess the efficiency, physical condition and programming of mechanical systems like ventilation, heating and thermostat.

The process ends by preparing a report which provides the estimate energy used based on local climate criteria, thermostat settings etc. This normally describes the energy used in a year and suggests impacts and ways to reduce the figures. Thus we now know of an effective way of how to do a home energy inspection using a thermal imaging camera.
