Building Energy Use

Choice of Technologies

The diversity of available brands and technologies for lighting, and the ease with which light globes are replaced makes it particularly important that this sector is subject to MEPS. It is also acknowledged that for these reasons, lighting is one of the most difficult technologies to regulate. Furthermore, the ease with which light globes are transported makes it particularly important that this technology is addressed at the regional level. The proposed activities for lighting are in accordance to the en.lighten Policy brochure, an international agreement that Belize has already committed to follow.[1]

In most homes the air conditioner is the largest user of electricity. Switching to high-efficiency air conditioners could reduce energy use for air conditioning by 20% to 50%.[2] Switching to newer and more efficient models of air conditioners can also have a positive environmental impact. Older models use ozone-depleting chlorofluorocarbons (CFCs) as a refrigerant and the newer models have switched over to hydrochlorofluorocarbons (HCFCs), which deplete 95 percent less ozone.

Fans are a very energy efficient way to circulate air, and increase the effectiveness of heating or cooling.  Although circulation of air is efficient, there have been substantially improvements in the energy efficiency of fans over recent years, and many of the older models in use consume unnecessary amounts of energy.

In most homes the refrigerator is the second-largest user of electricity. With most appliances you save energy by using them less, but this is not possible with refrigerators.  The main way to save energy with refrigerators is to use an efficient model.  Between 1993 and 2001 the energy efficiency of refrigerators improved by approximately 30%, new models are substantially more efficient.[3]
