Energy security is undeniably the backbone on which every strong economy is built. Demand for energy is globally on the surge as populations keep exploding. The issue of demand and supply gets quiet complicated as one narrows down to the electrical energy subsector for at least one reason; electrical energy can hardly be economically stored. Power utilities are therefore left with the sole alternative of supplying most at highest demand (peak demand) periods and less at base demand periods. This is however not a sure solution as irregularities exist on both supply sides and demand sides. Customer frustrations are therefore common within the power subsector. This situation is truer in the case of Ghana. Ghana has two main seasons; the dry and wet seasons. Electricity demand generally increases in the dry season. This is to a significant extent a result in higher demands for cooling during this season. With most of our means of cooling being mechanical, the situation creates more ambivalence. A more friendly approach is thus required to reduce the undue costs arising from conventional, mechanical cooling means.
– To establish the contribution of cooling load to overall demand.
– To reiterate the significance of natural cooling on demand curve-flattening.
– Establish effective windowing a sure approach towards reducing peak electricity demand.
– Create awareness on the need for structural engineers to incorporate effective windowing in structural designs.
A substantial amount of residential energy consumption is attributed to cooling devices; devices such as electric fans and air conditioners. Finding a more efficient means of cooling buildings will therefore be a breakthrough towards reducing residential energy consumption.
Cooling devices are devices that are employed to reduce temperatures to more bearing limits for residents. Most of these devices are energy inefficient with very high wattage ratings. The least wattage for an electric fan is 75W. Air conditioners’ wattages soar to as high as 1200W for room usage. This leads to peakage of electricity demands. Building for efficiency is a sure means of avoiding the lots of peak demands and its accompanying high costs. One of the several techniques applied in building efficiency is effective windowing. Effective windowing refers to window systems that transcend the technology of conventional window systems, and aims at reducing costs of ventilation.
Residential consumption make up a better half of Ghana’s energy consumption. Most of the energy consumptions of the residencies are as a result of the usage of cooling devices which have higher ratings. It’s therefore no nonsense to attribute Ghana’s energy insecurity to residential cooling devices. The wrath of energy instability on the nation is very significant – higher costs of production, resulting in inflation. The net effect of energy insecurity is economic break-down.
