Abstract

The Energy Efficient Lighting (EEL) Design and Savings Calculator (DSC) for Commercial Application is a handy tool intended for project engineers to have a quick reference in the illumination design. This project is specifically focused on selecting energy efficient lamps used notwithstanding its illumination requirement in the given area/task.

The EEL-DSC comprises of the rotary disk (inner and outer) and disk jacket. The inner rotary disk shows the various lamps type, lamp wattage, lamp light output, color temperature, color appearance, and color rendering group. Side A of the outer rotary disk displays the Lumen Method formula while side B shows the notations for Color Rendering Group (CRG), Correlated Color Temperature (CCT), and the Lamps type legend.

The disk jacket has two parts: the inner disk jacket and the outer disk jacket. The inner disk jacket (IDJ) illustrates the instruction manual and steps in calculation.

Table 1 indicates the recommended level of illumination and Table 2 the color rendering index (CRI) with lamp efficacy. The outer disk jacket (ODJ) illustrates the picture from DOE while Table 3 displays the Coefficient of Utilization (CU), the Maintenance Factor (MU) and Terminologies.

These parameters were simplified to help the engineers quickly estimate the design of energy efficient lighting system by selecting the lamps type, categories e.g. High-bay, low-bay and 2-Lamps, coefficient of utilization, and maintenance factors. The reflectance for ceiling, walls, and floor cavity were also simplified at 70%, 50% and 30% respectively. Finally, the total number of luminaires was determined.

Moreover, EEL-DSC for Commercial Application is one of the contributions of the Technological University of the Philippines (TUP) in the advocacy of the Department of Energy to address the barrier to use energy efficient lighting system in the Philippines and its goal to reduce Greenhouse Gas (GHG) emission in the energy sector. Furthermore, this project was funded by the United Nation Development Programme (UNDP) through the Philippine Efficient Lighting Market Transformation Project (PELMATP) – Department of Energy.
