C = Q* The sum of these two calculations gives the total initial conduction or convection through an object per year Q b = Q hb + Q cb Where Q b = energy lost by conduction (or convection) through the object per year, before the measure Q hb = heating energy lost before the measure Q cb = cooling energy lost before the measure Similarly, the final (after measure) conduction (or convection) must be calculated.
