What are the most energy-efficient walls?
The cladding of an energy-efficient wall should include materials with low emissivity and high reflectivity so to limit the absorption of radiant heat. Two examples of energy-efficient cladding systems in the market are exterior insulation and finish systems (EIFS) and insulated metal wall panels.

The best wall construction for a passive house design includes continuous insulation (CI), an air and moisture barrier, and a high thermal mass building system, all elements of insulated concrete form (ICF) wall systems. ICF also contributes towards superior IEQ and passive survivability.
Internal wall insulation
If your home has solid walls– and therefore you can't install cavity wall insulation – and you're wondering how to make your home more energy efficient, internal wall insulation may be an option. Internal wall insulation involves fitting insulation boards to the walls inside your home.
Energy efficient solutions for buildings include advanced materials such as thermal insulation foams and panels for both internal and external application, coatings that either reflect heat or light, phase change materials that can provide thermal inertia/ storage for buildings and help temperature control, and highly ...
Closed-cell foam is the most effective, with an insulation value of around R-6.2 per inch of thickness. Open-cell foam cells are not as dense and are filled with air, which gives the insulation a spongy texture. Open-cell foam insulation value is around R-3.7 per inch of thickness.

Green Walls & Roof
Made from gravel, steel, geo cloth and plants, green walls and roofs are natural, great at insulating (for both heating and cooling) and soften the hard lines of a build. As this is a living building material, it will need water and consistent care, and in some areas, replanting.
What is the most energy efficient wall insulation? Closed cell spray-foam insulation is the most energy efficient wall insulation. Applications can reach much higher R-values for each inch of thickness than other insulation products, with values as high as R-6.2 per square inch (roughly R-34 on a 2×6 wall).

The cavity wall is a special type of a wall that traps heat and helps it being the best option in insulation possible. The brick wall is not a great insulator as the ability to trap heat is much weaker than in cavity wall. Cavity wall is the best among all of it.
