Homeowners your hands one of the most important documents you can possess before you purchase a home! What every homeowner or potential homeowner absolutely needs to know and understand is this, you as a homeowner have ALL the responsibility to make sure your new home is going to function and be an energy efficient home.
This document is written for the homeowner to understand the city inspections. This article is not referring to the third party inspection completed by a licensed Professional Home Inspector.
If you are concerned about the energy efficiency for your new home the single most important item that impacts energy usage and monthly energy bills is the size of the home. The energy cost to operate your home is directly related to the size, shape and volume of your home. Home builders today are not supplying potential home buyers with two critical pieces of information you need to understand the energy efficiency of a particular home or if you are comparing the homes from two different home builders.
When an engineer designs and sizes the AC equipment for a building large or small he uses a load calculation method to determine how much heating and air conditioning capacity is needed to serve the new building. The same approach and method is supposed to be used today in new homes built in Texas. The home builders in Texas have been building homes in Texas since 2001 that will not meet the required energy code standard and design guides. The load calculation step is the very beginning and most important step in building a home for energy efficiency but is not being performed by builders today. This is simply because most builders do not pay attention, understand the energy code or understand load calculations. Attefallshus
The other problem or issue is that most homeowners have never heard about it and do not care as well. Most homeowners believe that someone else is taking care of this for them. As I stated earlier in this guide this is simply not true or being done.
Homeowners Have To Take Responsibility
How do homeowners know that one home is more efficient than another? The method used to
understand the efficiency of a home in regards to the heating and air conditioning systems is based on a unit of energy known as a “British Thermal Unit” (BTU). I am not going to get real technical here but I will give you the homeowner the information you need to go home shopping with and it is really very simple.
Three Efficiencies Regarding Home Building
1. Thermal Efficiency- Determined by the home construction methods and materials
used to build the home. It is the most important efficiency in home building.
2. Energy Efficiency – Measured and calculated by the conversion of energy input
(KW/BTU) into useful work output cooling/heating BTUH.
3. Overall Efficiency – Is the combination of both efficiencies above. Thermal Efficiency
has a huge impact on the Energy Efficiency rating and therefore will impact the
overall efficiency of the home.
As a homeowner this is what you need to know. The amount of energy required to heat and cool your home is directly related to the amount of heat gain your home experiences when it is warm outside and how much heat loss your home experiences when it is cold outside. This heat gain and heat loss is measured in BTUS. The amount of heat gain and heat loss is measured and defined on an hourly basis so the measurement is in BTUH. This stands for British Thermal Units per Hour. The higher the thermal efficiency of the home the lower the energy use is. As a homeowner you will receive a better return on investment for each dollar you spend to make your new home more thermally efficient than to build a very poor thermally efficient home and try to make up the overall efficiency with very expensive high end heating and air conditioning equipment. This approach simply does not work over the life of the home.
