Educational buildings are the most suitable type of building for the application of energy audit. Such measures can promote sustainability and ensure a comfortable and healthy environment for educational purposes. This study aimed to assess energy efficiency and conservation of the College of Engineering specifically the lighting system of the building. A walkthrough audit was made to acquire preliminary assessment on the building. A luxmeter was used to measure illumination (lux). The study showed that the illumination levels did not meet proper standards. Through data logger and theoretical calculations, it was determined that lighting system consisted 44% of total power consumption. These led to the development of a new lighting system (room E209 selected as a sample) composed of F28T5 lamps which improved lighting levels and saved more energy than the old F40T12 lamps. Through calculations, the new lighting systems showed an annual savings of Php5708 for room E209 alone with payback period of 2 years and 3 months. Less

This study is about the assessment of a potential microhydro system in an irrigation canal in Lower Magsaysay, Kuya, Maramag, Bukidnon to power streetlights. The assessment showed that the microhydro have enough potential just to power streetlights. The microhydro system designed utilizes cross flow turbine of 6 kW power output and generator with power rating of 6 kW. The microhydro, based on design specifications, can generate maximum power output of 6 kW, which is enough to power streetlights that can cover longer distance based on the guidelines set by the Department of Energy on road lighting. The microhydro turbine and generator have an estimated cost of Php 81,129.00 and the street light system at Php 308,844.00. Realization of these systems can greatly help the residents in the area in terms of accessibility, safety and security. Less

Biomass resources from forests and agriculture residues are underutilized and lost mostly in the provinces in Mindanao and other less developed areas in the country. This article focuses on the estimation of biomass available and energy potential of corn residue in Bukidnon. The study was carried out using survey questionnaires and government agriculture reports to investigate the potential biomass resources and the existing domestic and commercial uses of biomass in the province. Integration and analysis was done using ArcGIS platform and in mapping out geographic distribution and concentration of biomass resources. It is established that the annual biomass theoretical potential for Bukidnon is about 502,343.38 metric tonnes, which corresponds to an annual energy production potential of 2,252,016,879.08 MJ. Concentration of biomass theoretical potential is highest in District 2 and District 3 and consequently the energy potential of 144,220,522.03 kWH and 298,793,184.33 kWh, respectively. The outcomes of the present study indicate that for studies to develop site suitability analysis for power plant development may need to consider including other leading agronomic crops in the province.
