WHAT LIES BENEATH
Although ductwork and insulation are hidden from sight, they offer lots of energy savings if done right
Air-conditioning ducts are one of the most important systems in your home, and if the ducts are poorly sealed or insulated they can esult in high energy bills. Your home’s duct system is a network of tubes in the walls, floors, and ceilings. Ducts are made of sheet metal, fiberglass, or other materials.
In a typical house with forced air heating and cooling, 20% to 30% of the air that moves through the duct system is lost due to leaks, holes, and gaps in connections. This waste leads to higher utility bills and difficulty keeping the house warm or cool, regardless of the thermostat settings or efficiency of the heater or air conditioner. In new home construction or in retrofits, proper duct system design is critical. In recent years, energysaving designs have sought to include ducts and heating systems in the conditioned space.
According to Energy.gov, efficient and welldesigned duct systems distribute air properly throughout your home without leaking to keep all rooms at a comfortable temperature. The system should provide balanced supply and return flow to maintain a neutral pressure within the house. The main influences on demand for insulation materials are various international building codes and regulations. While these regulations act as a catalyst for growth, they also impose limitations by restricting the use of certain materials in specific applications. Energy costs are widely accepted as the prime motivator driving growth in insulation—both in commercial and residential applications—though other costs come into it as well, particularly in tightly managed projects or budgets. This is also true of production costs, of which energy often constitutes a large proportion, especially in the glass and mineral wool market, which uses considerable amounts of energy in furnaces and ovens.
As my market report says inside, a well-insulated residential construction is a cost-efficient as well as energy-efficient choice since it brings down cost generated by a heating or cooling system. Insulation is related to the interception of the passing of thermal energy between two objects from an area of higher heat assemblage to one of a lower heat concentration, thereby preserving heat in a specific layout. A building that is well-insulated saves utility bills and enables conservation of heat energy.
