Energy efficient home building is best described as an evolution because it is something that has occurred overtime. ?The federal government and several organizations have setup standards to calculate home efficiency but in most cases it something that only is encouraged and not required.
Most home builders, now a days, build an energy home with energy efficiency to appease the buyer because the rising cost of utilities have buyers asking the home builder what energy efficient building techniques they build into their home because buyer are also budgeting how much they will have to paying for utility when considering buying a new home.
So to answer the question ?what year did homes become more energy efficient,? the older the home, the less energy efficient it will be. ?The good news that there are some very simple energy efficient improvements that can be done that will improve the energy efficiency of a home. ?The number one improvement that can be done in improving home energy?efficiency?is increasing the R-value of insulation in the attic. ?Many older homes have between a R-13 to R-30 value insulation in where in most cases it is recommended to increase this R-value to somewhere between R-44 to R 48. ?Insulation is rather cheap so this improvement is typically well worth the money. ?Also placing radiant barrier on the inside of the roof will help keep the attic cool. ?Most companies are able to place spray radiant barrier in the inside of your roof. ?Lastly, placing solar fans in the roof, will help keep your attic cooler and help in the energy efficiency of your home. ?Changing out equipment, if probably the most costly upgrade to do but it absolutely?helps in improving a homes energy efficiency.
With any upgrade done to the home. ?I always recommend to do a cost analysis to determine your return on your investment which is how many months before your improvement pays itself back in the utility cost savings. ?If the return on your improvement makes sense to you then it is probably a good thing to do.
