Abstract

A method for generating a home energy efficiency label based on real-time measurements of gas-energy usage of a household and outside temperature data. The home energy efficiency label is calculated by correlating energy usage of the household to the outside temperature and presented to a home owner in real-time on a computer screen, thereby enabling prediction of potential energy savings by lowering indoor climate temperatures. The home energy efficiency label certifies home energy efficiency and can be used on a housing market including home appraising and financing.

Claims

1. A method for generating a home energy efficiency label comprising:

measuring, in real-time, said gas-energy usage of a household, said measuring comprising metering of normal volume constituting displacement of molar content per unit time by application of a gas meter compensated for temperature and pressure variations in natural gas flow;

obtaining, in real time, outside temperature data by at least one of;

obtaining outside temperature data from the Internet or by using a temperature measurement device outside of the household;

receiving by a household computer said real-time measurements of gas-energy usage and temperature data;

displaying said received data on a household computer screen;

correlating, in real-time, by said computer the received gas-energy usage to the received outside temperature data by applying statistical analysis, said correlating comprising;

antecedent

(a) calculating a ratio HEET0 of change in gas-energy usage to change in outside temperature about a fixed reference temperature TO characteristic for cold weather when heating is required by the following formula;

HEET0=[y(T0+Δ

T,{Ti})−

y(T0−

Δ

T,{Ti})]/(2Δ

T),

where Δ

T is a temperature difference and y(T,{Ti}) denotes an approximation curve that is a closest fit to the received data on gas energy usage versus the received data {Ti} on outside temperature T by statistical analysis;

(b) calculating the mean of ratio (a) over reference temperature TO given by the received outside temperature over a time period,

wherein (a) expresses the degree to which gas-energy usage in heating is influenced by cold weather and (b) expresses the degree to which gas-energy usage is influenced by the most recent weather pattern;

displaying the results of (a) and (b) on said household computer screen simultaneously with time history of said real-time gas-energy usage and outside temperature both for the same period of time, wherein said period of time is selected from a few minutes to a few years,

generating, by a computer, the home energy efficiency label comprising in one graph said approximation curve and said received data on enemy usage and outside temperatures, and the results of (a) and (b);

using the label to certify home energy efficiency on a housing market including home appraising and financing.

2. The method for generating a home energy label as in claim 1, further comprising:

using the label to predict potential energy savings associated with lowering indoor temperature by one degree;

displaying the predicted potential energy savings on the household computer screen to create continuous feedback to home owners to enable said home owners to adjust indoor climate comfort versus energy usage.
