Reliable energy forecasting helps managers to prepare future budgets for their buildings. Therefore, a simple, easier, less time consuming and reliable model which could be used different types of buildings is desired. In this paper, we have presented based on five years real data sets one dependent variable (the daily electricity consumption) six explanatory variables (ambient temperature, solar radiation, relative humidity, wind speed, weekday index building type). A single mathematical...

India, Pakistan, and Bangladesh (IPB) are the largest South Asian countries in terms of land area, gross domestic product (GDP), population. The growth these is impacted by inadequate renewable energy policy implementation over years, resulting slow progress towards human development economic sustainability. These developing blessed with huge potential for resources; however, they still heavily rely on fossil fuels (93%). IPB a major contributor to total consumption world its most...

The temperature of the photovoltaic module has an adverse effect on performance modules. converts a small portion energy from solar radiations into electricity while remaining wastes in form heat. In this study, water cooled photovoltaic/thermal system was analyzed to enhance efficiency by absorbing heat generated modules and allowing work at comparatively low temperature. For system, four two different types were used. To investigate cooling effect, modified making ducts their back surface...

The building sector consumes about 40% of the world’s primary energy. Seasonal climatic conditions have a significant effect on energy consumption in buildings. One famous methods used for decoding this seasonal variation buildings is “Degree Days Method”. Data has been widely published heating and cooling degree days different countries. Unfortunately, there very limited outdated data degree-days Pakistan. In study, yearly average regions Pakistan are established by using 30 year long-term...

In Pakistan, data for household electricity consumption are available in the form of monthly bills only, and, therefore, not helpful establishing appliance-wise consumption. Further, it does help relationship among and various driving factors. This study aimed to unlock Pakistan by analyzing investigating impact socioeconomic, demographic, dwelling parameters usage different appliances. The methodology adopted this was survey-based collection residential sector. For purpose, were collected...

The application of the nanofluids is suggested to enhance and improve efficiency solar thermal power system. In present study, three different (Fe2O3/therminol VP1, SiO2/therminol Cu/therminol VP1) are numerically investigated in parabolic dish collector that further integrated a combined cycle for hydrogen production. Heat rejects from also utilized drive single effect absorption (LiBr-water) Furthermore, comprehensive energy, exergy exergo-environmental analysis carried out by varying...

Rising temperatures, increase in population, and dense urban morphology have resulted increased cooling energy demands. The conventional degree-days method to calculate demand considers only the sensible heat load of air neglects latent component. This study aims estimate degree days based on index (by considering both loads) for current future years (2050 2080). Further, ventilation each these cities has been established unlock impact building’s total consumption years. results show that...

The present study investigates the performance of a multi-generation plant by integrating parabolic dish solar collector to steam turbine and absorption chiller producing electricity process heat cooling. Thermodynamic modeling proposed integrated is conducted using engineering equation solver investigate effect certain operating parameters on system. evaluated compared three different transfer fluids, namely, supercritical carbon dioxide, pressurized water, Therminol-VPI. useful gain...

Pakistan is facing a severe energy crisis of its history due to increase in the demand and lack investment mobilizing resources. This paper aims discuss outlook ways toward greener environment electricity production Pakistan. Gross domestic product population are major drivers behind growing for energy. Demand always with GDP growth. The growth forecasted by Ministry Petroleum & Natural Resources has shown an 0.75% 2012 compared 2011. been driven strong from industrial government sectors....

Parabolic dish solar collectors gain higher to thermal conversion efficiency due their maximum concentration ratio. The present research focuses by integrating the parabolic collector steam cycle producing power and rate of process heating. Pressurized water, therminol VP1, supercritical carbon dioxide are examined working fluids in collector. aim current is observe optimal operating conditions for each heat transfer fluid varying inlet temperature flow collector, combination these...

Universities in the United Kingdom that have installed Combined Heat and Power (CHP) technology are making good moves towards achieving their CO2 reduction targets. However, CHP may not always be an economical option for a university campus due to numerous factors. Identification of such factors is highly important before investment decision. A detailed technical, economic, environmental feasibility is, therefore, indispensable. This study aims undertake assessment typical attempts highlight...

This paper presents real time performance analysis of a silica gel based desiccant wheel dehumidifier. Thermodynamic model is also validated through comparison under wide range operating conditions for subtropical climate conditions. Initially, mathematical developed by using various set equations dehumidifier in engineering equation solver. After-wards, parametric the system performed including design and parameters such as: inlet air humidity ratio, temperature, regeneration rotation speed...

The current study presents a numerical and real-time performance analysis of parabolic trough collector (PTC) system designed for solar air-conditioning applications. Initially, thermodynamic model PTC is developed using engineering equation solver (EES) having capacity around 3 kW. Then, an experimental setup established with concentration ratio 9.93 evacuated tube receivers. conducted under the climate Taxila, Pakistan in accordance ASHRAE 93-1986 standard. Furthermore, integrated solid...

Academic buildings in a typical university campus occupy 42% of the total space and are responsible for nearly 50 percent energy use carbon emissions campus. Forecasting consumption this intensive building category could help higher education institutions taking saving initiatives revising their operating strategies. Reliable predictive techniques does not only forecasting building' consumption, but also identifying variety factors affecting that building. This study attempts to forecast...
