Overall control efficiency means the efficiency of a control system, calculated as the product of the capture and control device efficiencies, expressed as a percentage.Įnergy efficiency project means an energy efficiency measure or combination of measures undertaken in accordance with a standard offer or market transformation program. Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff.Įnergy efficiency measure means equipment, devices, or materials intended to decrease energy consumption, including, but not limited to, upgrades to a building envelope such as insulation and glazing improvements in heating, ventilating and cooling systems automated energy control systems improved lighting, including daylighting energy‑recovery systems combined heat and power systems or another utility cost‑savings measure approved by the governing body. Transfer efficiency means the ratio of the amount of coating solids adhering to the object being coated to the total amount of coating solids used in the application process, expressed as a percentage. Thermal efficiency means the useful electric energy output of a High-efficiency cogeneration means cogeneration meeting the criteria laid down in Annex II ![]() The irrigation efficiency for purposes of this ordinance are 0.75 for overhead spray devices and 0.81 for drip systems.Ĭapture efficiency means the weight per unit time of VOC entering a capture system and delivered to a control device divided by the weight per unit time of total VOC generated by a source of VOC, expressed as a percentage.Įfficiency means the gas turbine manufacturer's rated heat rate at peak load in terms of heat input per unit of power output based on the lower heating value of the fuel.Įnergy efficiency means measures that reduce the amount Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. Irrigation efficiency (IE) means the measurement of the amount of water beneficially used divided by the amount of water applied. The available information, reported here, refers mostly to the situation before 6 April 1994.Īirflow efficiency was mentioned several times throughout the presentation as it was analyzed and improved to its final state. Depending on the room, we might need to perform multiple air changes per hour to achieve our desired air quality in that room.Examples of Airflow efficiency in a sentenceĪirflow efficiency is the ratio of airflowspeed airflow, power consumption, and airflow efficiency information for the13 American Lighting Association (‘‘ALA’’) (09/ 08/2006) #523596–00003 People’s Republic of China (‘‘PRC’’) () #523596–00001 divided by power consumed by the motor and Hunter Fan Company (‘‘Hunter Fan’’) ()controls at a specific ceiling fan setting expressed in CFM per watt (‘‘CFM/Watt’’).12 ENERGY STAR Testing Facility Guidance Manual, Version 1.1 (Dec.Īirflow efficiency appears to be a nearly- universal metric used to describe the efficiency of ceiling fans and consists of airflow (i.e., theservice provided by a ceiling fan), as measured in cubic feet per minute (CFM), divided by power consumption, as measured in watts (W).Īirflow efficiency appears to be a universal metric used to describe the efficiency of ceiling fans and consists of airflow, i.e., the service provided by a ceiling fan, as measured in cubic feet per minute (CFM), divided by power consumption, which is measured in watts (W). In order to remove these air pollutants, we have to change the air in the room by introducing new volumes of air. Having adequate ventilation and airflow in a room is essential for breathing and for some appliances and equipment to work properly.Īside from that, with correct ventilation, we can control the humidity and temperature in a room and quickly remove any odors, fumes, and even particles that might linger, like in the kitchen or living room. Each room has a specific purpose, and we stay in each room for different amounts of time during the day.ĭepending on the activities we do in a room, the ventilation required to maintain a fresh air flow will change. In most workplaces, we usually have a lobby or receiving area, hallways, function rooms, offices, restrooms, and so much more. We commonly find a living room, bedroom, dining area, kitchen, and bathroom in a basic house. In any building, there will be a variety of rooms with various functions and purposes. ![]()
