14. Scope management
• Vision:
Luxurious touch as it should be with great savings of energy and money.
• Mission:
Energy management, Customer satisfaction, comfort, and electricity bill are
our duties.
• Objectives:
the project aims to save our usage of electricity which reflect on the bill and the
energy demand.
 This project mainly aims to solve the energy problem the government or the
country is facing in the upcoming years.
 Spreading the awareness about the importance of energy savings.

15. Components of feasibility study:
• Executive summery:
 we mainly took about who we are, what the problems we solve and the
solution.
 this part summarize the whole feasibility study document.

16. Components of feasibility study:
• Why this this project and it’s goal:
 This could be discussed from 3 prospective:
1) General:
 It helps in solving the electrical power problem and the consumption efficiency.
2) Egypt:
 Egypt is seeking to be Industrial country which means we should save energy from old
loads.
 Peak hours loading.
3) Customers:
 Save money from electricity bill.
 This could be a replacement for smart meters.

17. Technical feasibility
• It helps in determining whether the technical resources meet capacity
and whether the technical team is capable to convert the ideas into
working systems.
 Ability to Execute:
 Do we have the knowledge required?
 Most of required knowledge needed is available in us and we have sources
where we can get the knowledge required like our supervisors or connections
 Can we get the components required?
• Our searches say yes most of materials available in the market

18. Market feasibility
 Market feasibility studies help identify market competition, potential markets,
and market analysis to assess a business idea.
 Customer segmentation:
 project target mainly upper-middle class and higher class in the long-term goal.
 But for the short-term goal we can specify upper class as a start.
 Then build our brand and increase our knowledge going through customer
relationship stations, then target another small segment.

19. Market feasibility
• Competition:
1) From concept or technical prospective:
 Our main competitor in the market is KNX.
Our project KNX
Control logic same same
Cost Low High
Technicalities Needs a specialist to
program the system
Easy to program but needs a high cost
certification to program the system
Installation Very easy Complex and need to be planned from beginning
Flexibility High High
Components Can be from various
manufacturers
Need to be from same manufacturer
Scale of application Small and medium scale Upper medium and large scale
Starts from 500m

20. Market feasibility
• Also, there is more competitors we care about like:
1. OT-SOLUTIONS
2. DOMI
3. LEGRAND
4. ENTECH
5. TCI.
• So, it is not a blue ocean market, but we have chances.
 Why we are different?
• We mainly focus in the quality, but the price is one of our main values we propose.
• Our components will be open source system.
• We will provide good maintenance service and communicate regularly with them to
build good customer channel and relation.

21. Financial feasibility study
• Its related to how much start-up money is needed, sources of capital, returns on
investment, and other financial considerations.
Sources of funding we can use:
1-angel investors.
2-incubators and accelerators.
3-bank loans.
4-capital ventures.

22. Analysis
• We made a questionnaire on social media to collect data and we have got data of
160 apartment data.
• Results
 Main customers interested in trying our project located in CAIRO.
 Responses from:
 Apartments = 91.84%, Villas = 6.91%, Offices = 1.25%
 Areas ranges  75 m2:500 m2
 Average Area = 150 m2
 76.1% have Air Conditioners
 Average number of AC devices is 2
 Average AC is 1.5 HP
 Electricity Bill ranges  70 EGP: 4000 EGP
 Average bill = 510 EGP

23. Analysis
• According to calculations by the Fraunhofer Institute, smart home control can
save up to 40% of heating costs.
• That is certainly the ideal scenario. After all, heating costs depend on many
factors and therefore many manufacturers report savings of up to 30% per year
which seems a realistic and achievable value.
• So, the average of the bill charge will be in range of 355 EGP

24. Materials cost
• According to our tests we found that PIR sensor can cover up to 56 m2
• Then in average we will need about 3:4 sensors to cover an average apartment
• PIR sensor price = 200 EGP
• LDR price = 50 EGP
• BT100 sensor price = 120 EGP
• Controller price = 5000 EGP
• Wiring price = 750 EGP

25. Materials cost
• Cost-Benefit Analysis
• Investment = 6720 EGP
• Saving/year = 1860 EGP
• Interest rate in Egypt = 9.75%
• Lifetime of components = 10-15 years

• Payback Period = 4.668 years
• Cash Flow Return Rate = 11.91% per year
• ROI = 29.2%

27. • Depending on our calculations we can say
that the project is Feasible
