How have building codes in Texas changed over the past years? Are new houses better built than old ones?

How much safer and more energy efficient are new houses in Texas than old houses? What year(s) did the more stringent building codes go into effect?

I dont know what year the building codes changed but I can tell you that I have lived in a home built in the 1920s and 1970s and now reside in a home built 2 yrs ago. The home from the 1920s and the house from the 70s were only 300 sq feet difference (2500 sq ft for 1970s) and my current home built 2 yrs ago is 3500 sq ft and it costs me 40% less to heat and cool my home then it did the house from the 1970s. If you have a choice go with a younger home unless the older home has been remodeled with new windows and insulation.How have building codes in Texas changed over the past years?

You will find that the codes change year to year I am in new home construction and am dealing with a change this week
