Background. Estimated Energy Requirement (EER): Estimated Energy Requirement (EER) is the average dietary energy intake that is predicted to maintain energy balance in healthy, normal weight individuals of a defined age, gender, weight, height, and level of physical activity consistent with good health.
Also, What is EER used for?
The EER is based on calculations that account for an individual’s energy intake, energy expenditure, age, sex, weight, height, and physical activity level. Including physical activity level in the calculations makes determining energy expenditure possible and achieving energy balance a more realistic goal.
Similarly, How do you calculate EER for refrigerator?
EER = Heat Output / Power Input
If this unit uses 1,200 watts of electrical energy, its rating is calculated to 8.3, as the sum of 10,000 BTU divided by 1,200 watts, equals 8.3.
Herein, How is Schofield equation calculated?
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985.

| > 60 | 11.711 × W + 587.7 | 164 |
What is BMR formula? Calculate Basal Metabolic Rate
Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

What is the minimum EER rating?
Today’s cooling systems generally achieve a minimum Energy Efficiency Ratio (EER) rating of 10, though some states, as detailed below, have higher requirements.
Does EER matter?
Significant energy savings – Low energy consumption translates to lower electricity bill. Lower utility bills mean more money-savings. Enhanced cooling comfort – Air conditioners with a high EER are also known to be more effective in terms of cooling performance due to better technology, design, and components.
What is unit of EER?
A room air conditioner’s efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.
What is EER refrigerator?
EER refers to the cooling efficiency of the unit. For refrigerators and freezers, the yellow energy guide bears the Energy Efficiency Factor (EEF) of the unit. The higher the energy efficiency rating, the lower the energy consumption.
How much energy do I need per day?
The average adult needs about 8700 kilojoules (kJ) a day to maintain a healthy weight. But it varies quite a bit – some people need more and others less. Many factors influence how much energy you need, such as: how active you are.
How do I calculate my BMR manually?
The following equation provides this calculation: BMR = (height in centimeters x 6.25) + (weight in kilograms x 9.99) – (age x 4.92) + 5. For example, if your height is 178 cm, your weight is 78.6 kg and your age is 37, you would use: (178 x 6.25) + (78.6 x 9.99) – (37 x 4.92) + 5 = 1,721 calories per day.
What is the best BMR formula?
BMR formula
There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively: BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years]) BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])
What is a good BMR?
An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day.
How are EER cops calculated?
Cooling Load – Convert kW/ton to COP or EER
What is a good EER rating?
Generally, an EER of 12 or above is considered energy efficient, however, when comparing two models, the one with the higher EER is more energy efficient regardless of whether or not it is above 12.
Is a lower EER better?
The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.
What is EER in HVAC?
The Energy Efficiency Ratio (EER) of an HVAC cooling device is the ratio of output cooling energy (in BTU) to input electrical energy (in watts) at a given operating point. EER is normally calculated with a 95 °F outside temperature and an inside (return air) temperature of 80 °F and 50% relative humidity.
Is 9.5 EER good?
The average EER rating of portable AC units is about 8.5. That means buying ones below EER 8.5 is not advisable and buying those above 8.5 is quite a smart move efficiency-wise. The most energy-efficient portable AC unit (Whynter Dual-Hose) has an EER rating of 11.2.
Is a higher EER rating better?
A room air conditioner’s efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.
What is a good EER number?
Generally, an EER of 12 or above is considered energy efficient, however, when comparing two models, the one with the higher EER is more energy efficient regardless of whether or not it is above 12.
What is a good EER rating for AC?
12 EER rating is an excellent energy-efficiency rating for an air conditioner. Some of the best devices can even reach more than 12 EER. The best mini split air conditioners have an extremely high 12+ EER rating (check them here).

What is EER and COP in AC?
The terms COP (coefficient of performance) and EER (energy efficiency ratio) describe the heating and cooling efficiency of air conditioners. They indicate the ratio of heating or cooling provided by a unit relative to the amount of electrical input required to generate it.
Does EER include fan energy?
Where efficiencies ratings, such as EER and COP, include fan energy, the descriptor shall be broken down into its components so that the fan energy can be modeled separately”. So it sounds like I am not suppose to include my supply fan energy in my coil EER.
