Energy Efficiency

What is Energy Efficiency?


energy efficiencyEnergy efficiency has to do with the amount of energy it takes to cool and heat up the house as well as to keep all appliances working. Your home is energy efficient when it uses less energy to provide the same result. For a light bulb to be more energy-efficient, it must provide the same light with less energy. For an air conditioner to be energy efficient as well, it must provide the same amount of cooling or heating power with less use of energy.

How to make your house more energy efficient?


There are THREE ways to improve the energy efficiency of your home:


1.   One is to reduce the need for energy by improving the thermal envelope of the home. Eliminating air leakage to/from the house will allow or keep the desired in-house temperature and comfort at fewer costs.


2.   The second method is to improve the efficiency of electrical devices.


3.   The third is energy conservation. Although energy conservation does not necessarily imply energy efficiency, it is all about changing the habits of homeowners and the way they use make use of devices that use up energy.


Where does energy go in a typical house in Houston? 


The chart below shows what consumes energy in the house and the percentage of energy use per category. We will explain each one and outline the ways of how to reduce the amount of energy being utilized in each category.

Energy Consumption in Houston

As you can see, the half of energy usage in a typical home is related to thermal comfort: space cooling 29% and heating 20%.

In Houston, the biggest potential for the improvement of energy efficiency is to reduce the demand or the energy used to heat and to cool your home. To do that, you have to employ a two-dimensional approach:


1. The first approach is to reduce the amount of heat and humidity getting into the home.


Home Performance Inspection will allow you to do that. Home Performance compared with energy efficiency is about reducing air and duct leakage as well as related pressure differentials, enhancing insulation windows and other products that prevent heat from entering the home.


2. The second approach is to improve the efficiency of the air conditioner.


The modern air conditioning systems have energy efficiency rating. Below are the current standards for manufacturers of heating and cooling equipment:




SEER (Season Energy Efficiency Ratio)

The smallest rating for a brand-new air conditioning component is 13-SEER.

The HVAC system becomes more efficient if its Season Energy Efficiency Ratio is highly rated than if it is not.

AFUE (Annual Fuel Utilization Efficiency)

HPSF (Heating Seasonal Performance Factor)



As a consumer, you should understand that the energy efficiency rating of the air conditioning equipment is not everything. How the system is designed and installed has a significant impact on the real energy efficiency. The rating only tells you about the effectiveness of a particular system in an ideal environment and not how it will actually perform in your home.

At LiveWell, we provide air conditioning design as well as engineering services so that the air conditioning system is correctly applied to your home.

Energy Efficiency and Refrigerator

refrigerator and energy efficiency

Refrigerator consumes about 10% of annual energy usage in a single home. It is like a mini-air conditioner; it has a compressor as well as a condenser, and that’s why it uses so much energy. It takes much more energy to make something cold or warm compare to lighting up a TV screen or electric light bulb. Generating heat or initiating a cooling system is energy intensive. When we carry out energy audit, we always calculate the energy efficiency of refrigerator (2400).


Energy Efficiency and Water Heater

water heater and energy efficiency

The next category of energy consumption in a house is a water heater – it take 23% of all energy consumption in a house. Heating of water for household use is usually the largest domestic energy expense, second only to cooling and space heating. Anytime you heat water, it requires a lot of energy. Think, by the time you heat/cool your food, yourself and your water – it comes down to 83% of your energy bill.


When we perform energy audit, we evaluate the energy efficiency of a water heater and give a report on its efficiency factor to help you identify what areas have the greatest potential for improvement to save money on the annual energy bill.


The Truth about Energy-Efficient Appliances

do energy efficient appliances really help?

The last 18% of power consumption is made of other appliances and lights, which are all light bulbs and everything you plug in (personal computers, television, phone chargers, etc.).


If you reduce the usage of all these items, it won’t do much for your annual energy savings. Sealing one duct leak can have the same energy saving impact as replacing all your light bulbs with CFL or LED. So fixing the air conditioning and all air leaks will save you money, and you can still enjoy warm light in the house.



At LiveWell, we are committed to improving the energy efficiency of the house to the full and providing our customers with honest and detailed evaluation of every aspect of the home that affects the comfort, health, as well as their personal safety.
