#2: Energy Audit To Diagnose and Identify Problem Areas

Home energy consultant Chris Kennedy used thermal imaging camera to perform a whole-house energy audit.

He found a long list of opportunities to improve the overall energy efficiency of the house, including heat loss due to poor insulation that caused huge temperature difference between the studs, while the biggest point of heat loss came form the attic.

Check out the video below, including insulation tips from home energy specialists on how to fix these common energy efficiency problems in old houses (eg. with Attic Tent Cover) — to save significant utility costs in long term.

#5: Tips to Properly Insulate the Attic With Air Sealing

If the attic of an old house is improperly sealed, all the conditioned air that you paid to cool and heat will leak into the attic and escape to the outside.

An energy efficient attic features a combination of thorough air sealing, a layer of insulation within the U.S. Department of Energy R-Value recommendations, and proper roof vents to prevent ice damming and mold. Air ducts that run through an unconditioned attic also need to be properly insulated and air sealed.

Energy saving experts Mike Rusk and Larry Janesky shared their attic insulation tips and ideas in this video.
 

 
 

#6: Sealing Air Leaks After DIY Old House Inspection

Mark Hatten of 2stroketurbo bought a FLIR One Thermal Imaging Camera which is designed for Android and iOS devices.

He installed the free app on his Samsung Galaxy S6 smart phone, and used the thermal camera to conduct an inspection on his old house – as shown in video below.

Matt found it comes in very handy for sealing cold air leaks and drafts on a older home, with several air leakage issues and cold spots were detected.
 

 
One concern on this “DIY home improvement” video is that, Mark should not use fill foam near the electrical wiring area, because expanding foam is a flammable substance.

While putting foam in electrical outlets may lead to fire, you can avoid this risk by using pre-shaped fire retardant plastic foam inserts instead. For example: Frost King electric outlet and switch sealers.
 

#7: Internal Solid Wall Insulation and Renovation

This video shows retrofit insulation applied to the interior surfaces of the walls of a 100-year-old house in UK, which was built with solid (no cavity) walls.

#11: New Windows May Not Solve Air Leakage Problem

In the video below, energy consultant Tim Courtier conducted an home energy audit on the windows, doors, attic space, basement, and bedroom.

Interestingly, Tim found that the house actually has a lot of air leakage around and underneath the NEW windows themselves, and this will increase the energy consumption.

So, before you spend money to improve your old house insulation and energy efficiency —

the most important thing to do is to first find out where your house is losing the energy and why, without guessing.

Does your old house have crawl space?

In this case study, Larry Janesky demonstrates one of the best ways to insulate a crawl space and make it not only energy-efficient, but also fully protected against high humidity and the typical moisture-related problems that plague millions of crawl spaces across the United States and Canada.

According to Larry, this homeowner now enjoys a healthier and more comfortable home: No more humidity, mold and nasty smells from the crawl space during the summer, and no more cold drafts and cold floors during the winter.

The energy bills of this old house also reduced significantly, because the HVAC system works more efficiently without losing or gaining heat through the crawl.
