Abstract
The proposed project aims to apply energy management in the existed building in Palestine since buildings represent a large proportion of energy consumption which is almost 70% of the total consumption in the country. Schools would be a considerable graduation project because they are considered to be one of the most popular buildings in the country, and as we aim to increase the awareness of the importance of energy management as a mean of reducing energy consumption, and increasing energy efficiency which leads directly to human comfort.
To do so, a suitable software program “Designbuilder” was defined in which all the building components were built and all the parameters that affect the energy system were defined also. The software program was chosen for its reliability and variety of parameters it provides which help in evaluating the energy situation.
Second part includes the simulation and the analysis of the current energy situation of the school building, in which heating and cooling design were calculated, and the comfort data were shown. The results showed that lighting consumes the largest proportion of electricity nearly 75% and the peak season is winter which means that the school needs heating improvements.
The final part of the first part was few trials of improvements included HVAC system and LED lamps that have been applied into the Designbuilder to estimate their feasibility. And the results showed that the comfort sufficiently increased but the electricity consumption also increased.
For the second part of our graduation project, three different algorithms and criteria were used and applied for designing the grid-connected PV system. In addition to the hand sizing and conventional PV sizing calculations, The results shows that school needs 11 kW PV and the SPP is nearly 5 years .PVsyst software and DesginBuilder software were also used.This was done in order to compare the results and come up with the best possible results.
