Introduction

The storage of electrical and heat energy is an important aspect in various institutions such as
universities. Depending on numerous knowhow, it permits the keeping of excess energy
awaiting usage in the coming hours, days or months. This paper simply articulates the
optimization of electrical and heat storage in university building and there are several ways that
can be used by various universities to store the energy and this includes;
 Phase Change Material tanks(PCM)
 Building thermal mass (Kerry, 2010, p. 103)
 Hot water tank (HW) (Dincer, 2011, p. 98)
 Thermochemical material (TCM) (Hall, 2010, p. 34)
State- of- the- art
Thermal and electrical energy mainly develop as a result of a combination of heat and power
plant. This involves the residential micro-CHP plants which have an advanced energy proficiency
than conventional thermal power system thus resulting to a reduction in ecological effect,
mitigated greenhouse release of gases, reduce consumption of fuel and increase in economic
profitability. The accumulation of thermal energy is done when the price of electricity in the
market is low and discharged when the price is high as mentioned by Katulic et al 2004. The
research was also conducted showing the yearly power demand and also cold climate with a
high penetration of electric space heating as shown below;

An efficient operation of the production unit at more efficient loads comes as a result of the
heat storage system (Fleischer, 2015, p. 56). And the accumulation of heat can be done using
three mechanisms which include;
a) Upsurging the working fluid temperature or heat carrier (Hall, 2010, p. 34).
b) Transforming the working fluid phase (Hadorn, 2013, p. 89).
c) Thermochemical amassing of heat (Kosny, 2015, p. 67).
The idea of associating or incorporating a system of thermal energy storage to a prevailing
combined heat and power which assist in upgrading the productivity of energy decades started
a long time ago (Paksoy, 2008, p. 129). The preceding writers did not pay much attention to the
notion of having a very powerful and squeezed system of storage (Paksoy, 2008, p. 54). The
storing of energy has been acknowledged as a significant answer for decentralized energy
system. The energy consumption in building conducted in a few selected countries is shown by
the bar graph below;
