【能源標籤全攻略】如何透過標籤選擇最慳電家電？
現代家庭對電器的需求日益增加，但能源消耗也隨之上升。為了降低電費並減少對環境的影響，消費者應學會挑選節能家電。能源標籤提供了一個直觀的方式，讓我們能夠比較不同產品的能效，從而選擇更環保、更節能的家電產品。本文將介紹能源標籤的作用、如何解讀標籤上的信息，以及如何根據標籤來選擇最適合你的節能家電。
什麼是能源標籤？
1. 定義
能源標籤是一種政府認證的標籤，顯示家電產品的能源效益（Energy Efficiency）。標籤的目的是幫助消費者輕鬆比較同類產品的能效，選擇更環保和節能的產品。
2. 香港的強制性能源效益標籤計劃（MEELS）
由機電工程署（EMSD）管理，規定某些家電必須貼上能源標籤。涵蓋產品類別包括空調機、電雪櫃、洗衣機、抽濕機、電視機。
3. 其他國家的能源標籤
各國能源標籤可能有所不同，例如：
o 歐盟能源標籤（A+++ 至 D）。
o 美國能源之星（ENERGY STAR）。
o 中國能效標識（1級至5級）。
o 歐盟能源標籤（A+++ 至 D）。
o 美國能源之星（ENERGY STAR）。
o 中國能效標識（1級至5級）。
能源標籤的分級與含義
1. 香港的能源標籤根據產品的能源效益進行分級，分為 1級（最省電）到5級（最耗電）
o 1級（綠色）：能源效率最高，最慳電，推薦選擇。
o 2級、3級（黃色）：能源效率較高，但仍可改善。
o 4級、5級（紅色）：能源效率較低，較耗電，不建議選購。
o 2級、3級（黃色）：能源效率較高，但仍可改善。
o 4級、5級（紅色）：能源效率較低，較耗電，不建議選購。
2. 能源標籤的計算方式
透過測試家電的能耗表現，計算出其能源效益指數（Energy Efficiency Index, EEI）。根據 EEI 分數決定該產品屬於哪個級別。
如何解讀能源標籤上的資訊
1. 每年耗電量（kWh/年）
• 這是指產品在標準使用情境下，每年大約會消耗多少電量（以千瓦時 kWh 計算）。
• 數字越低，代表產品越省電，電費越便宜。
• 數字越低，代表產品越省電，電費越便宜。
2. 產品特定數據
• 雪櫃：顯示冷藏與冷凍室的總容積（升），幫助消費者選擇合適容量的產品。
• 洗衣機：顯示洗滌能力（公斤）、用水量等數據。
• 空調機：顯示製冷量（kW）、能源效益比（EER）。
• 電視機：顯示螢幕尺寸與耗電量。
• 洗衣機：顯示洗滌能力（公斤）、用水量等數據。
• 空調機：顯示製冷量（kW）、能源效益比（EER）。
• 電視機：顯示螢幕尺寸與耗電量。
3. 測試標準
標籤上的數據都是根據機電工程署指定的標準測試條件得出的，確保公平比較。

透過能源標籤計算電費
• 公式計算
o 年電費 = 每年耗電量（kWh） × 本地電費（$/kWh）
o 例如：一部年耗電 300kWh 的空調機，若本地電費為 $1.2/kWh： 年電費 = 300 × 1.2 = $360
o 選擇1級標籤的冷氣機，可能每年可節省約 $100-$200 的電費。
o 例如：一部年耗電 300kWh 的空調機，若本地電費為 $1.2/kWh： 年電費 = 300 × 1.2 = $360
o 選擇1級標籤的冷氣機，可能每年可節省約 $100-$200 的電費。
能源標籤提供了一個簡單直觀的方式，讓我們能夠比較家電的能源效益，從而選擇最慳電的產品。透過選擇1級標籤的家電，不僅可以減少電費開支，還能減少碳排放，為環境保護盡一份力。消費者購買時應注意標籤上的資訊，並根據自身需求選擇適合的節能產品。

【Energy Labels Guide】How to choose the most energy-saving appliances?
Modern households are increasingly demanding electrical appliances, but energy consumption is also rising accordingly. To reduce electricity bills and lessen environmental impact, consumers should learn to choose energy-efficient appliances. Energy labels provide an intuitive way for us to compare the energy efficiency of different products, allowing us to select more environmentally friendly and energy-saving appliances. This article will introduce the role of energy labels, how to interpret the information on the labels, and how to choose the most suitable energy-efficient appliances based on the labels.
What is an Energy Label?
1. Definition
An energy label is a government-certified label that indicates the energy efficiency of electrical appliances. The purpose of the label is to help consumers easily compare the energy efficiency of similar products and choose more environmentally friendly and energy-saving options.
2. Mandatory Energy Efficiency Labeling Scheme in Hong Kong (MEELS)
Managed by the Electrical and Mechanical Services Department (EMSD), this scheme requires certain appliances to display energy labels. The product categories covered include air conditioners, refrigerators, washing machines, dehumidifiers, and televisions.
3. Energy Labels in Other Countries
Energy labels may vary by country, for example:
o EU Energy Label (A+++ to D)
o ENERGY STAR in the United States
o China Energy Efficiency Label (Level 1 to Level 5)
o EU Energy Label (A+++ to D)
o ENERGY STAR in the United States
o China Energy Efficiency Label (Level 1 to Level 5)
Classification and Meaning of Energy Labels
1. Energy Labeling in Hong Kong
The energy label in Hong Kong classifies products based on their energy efficiency, ranging from Level 1 (most energy-efficient) to Level 5 (least energy-efficient):
o Level 1 (Green): Highest energy efficiency, most energy-saving, recommended for selection.
o Levels 2 and 3 (Yellow): Higher energy efficiency, but still room for improvement.
o Levels 4 and 5 (Red): Lower energy efficiency, more energy-consuming, not recommended for purchase.
o Level 1 (Green): Highest energy efficiency, most energy-saving, recommended for selection.
o Levels 2 and 3 (Yellow): Higher energy efficiency, but still room for improvement.
o Levels 4 and 5 (Red): Lower energy efficiency, more energy-consuming, not recommended for purchase.
2. Calculation of Energy Labels
The energy efficiency index (EEI) is calculated by testing the energy consumption performance of appliances. The EEI score determines which level the product belongs to.
How to Interpret Information on Energy Labels
1. Annual Energy Consumption (kWh/year)
• This indicates the approximate amount of electricity the product will consume annually under standard usage conditions (measured in kilowatt-hours, kWh).
• A lower number indicates that the product is more energy-efficient and will result in lower electricity bills.
• A lower number indicates that the product is more energy-efficient and will result in lower electricity bills.
2. Specific Product Data
• Refrigerators: Displays the total volume of the refrigeration and freezing compartments (liters), helping consumers choose the appropriate capacity.
• Washing Machines: Shows washing capacity (kilograms), water consumption, and other data.
• Air Conditioners: Displays cooling capacity (kW) and energy efficiency ratio (EER).
• Televisions: Shows screen size and power consumption.
• Washing Machines: Shows washing capacity (kilograms), water consumption, and other data.
• Air Conditioners: Displays cooling capacity (kW) and energy efficiency ratio (EER).
• Televisions: Shows screen size and power consumption.
3. Testing Standards
The data on the label is derived from standard testing conditions specified by the EMSD, ensuring fair comparisons.
Energy-Saving Tips for Purchasing Various Household Appliances
• Choose an inverter air conditioner, which can save about 40% more electricity compared to traditional models.
• Opt for a Grade 1 energy label for greater energy efficiency and environmental friendliness.
• Installation location: Avoid direct sunlight to reduce indoor-outdoor temperature differences and enhance efficiency.
• Clean the filter regularly to improve cooling efficiency and reduce energy consumption.
• Opt for a Grade 1 energy label for greater energy efficiency and environmental friendliness.
• Installation location: Avoid direct sunlight to reduce indoor-outdoor temperature differences and enhance efficiency.
• Clean the filter regularly to improve cooling efficiency and reduce energy consumption.
2. Refrigerator
• Select a refrigerator with a suitable capacity to avoid unnecessary energy wastage.
• Properly space out food items to allow air circulation and enhance cooling efficiency.
• Avoid frequent door opening to reduce compressor runtime.
• Properly space out food items to allow air circulation and enhance cooling efficiency.
• Avoid frequent door opening to reduce compressor runtime.
• Use an appropriate amount of water and detergent; excessive use can affect energy efficiency.
• Choose a Grade 1 labeled drum washing machine, which is more water and energy-efficient than traditional top-loading models.
• Wash full loads whenever possible to minimize unnecessary wash cycles.
• Choose a Grade 1 labeled drum washing machine, which is more water and energy-efficient than traditional top-loading models.
• Wash full loads whenever possible to minimize unnecessary wash cycles.
4. Dehumidifier
• Choose a dehumidifier with the appropriate dehumidifying capacity (measured in L/day).
• Set the humidity level appropriately (generally recommended at 50%-60%) to avoid excessive operation.
• Set the humidity level appropriately (generally recommended at 50%-60%) to avoid excessive operation.
5. Television
• Opt for an LED TV, which is more energy-efficient than traditional LCD and plasma TVs.
• Turn off standby mode; when not in use, turn off the power to reduce standby power consumption.
• Turn off standby mode; when not in use, turn off the power to reduce standby power consumption.
Calculating Electricity Costs Through Energy Labels
• Formula Calculation
o Annual electricity cost = Annual electricity consumption (kWh) × Local electricity rate ($/kWh)
o For example, for an air conditioner consuming 300 kWh annually, with a local electricity rate of $1.2/kWh: Annual electricity cost = 300 × 1.2 = $360
o Choosing an air conditioner with a Grade 1 label could potentially save around $100-$200 in electricity costs annually.
o For example, for an air conditioner consuming 300 kWh annually, with a local electricity rate of $1.2/kWh: Annual electricity cost = 300 × 1.2 = $360
o Choosing an air conditioner with a Grade 1 label could potentially save around $100-$200 in electricity costs annually.
Energy labels provide a simple and intuitive way to compare the energy efficiency of household appliances and choose the most energy-saving products. By selecting appliances with Grade 1 labels, consumers can not only reduce electricity expenses but also lower carbon emissions, contributing to environmental protection. Consumers should pay attention to the information on labels and choose energy-efficient products based on their own needs.
