1.23.2 Glass Types Application Case Study

1.23.2 Glass types Application.
This section will compare the effect of using some of the glass common types on the total cooling thermal load of the building. The cost of using these types will be studied as a comparison (effect VS Cost).
1.23.2.1 Simulation Goal
The Goal of this study/simulation is to find out the relation between the Building Glass type and the total amount of the cooling load needed to keep the building temperature within the comfort zone range. The Simulation focuses on the following three questions:
• The energetic performance of glass types (does the using of a high energy performance glazing reduce the required cooling thermal load?).
• Cost as initial cost and life cycle cost. (Is it financially beneficial to invest
This cost including the manufacturing, transportation and installation Costs.
The feasibility Study will Consider the Double Glass with Air fill as the reference case and the using of the other higher thermal performance glass types as investment in the project by comparing the Glass type saving cost (due to the energy saving) with the glass type implementation cost in order to find out the Investment Return Period. o Reference case: Double Glass with Air fill. o Glass type (x) cost difference = Cost of Glass type (x) - Cost of reference case. ………… (A). o Glass type (x) saving Thermal Performance = (Total annual Cooling Loads for reference case - Total annual Cooling Loads for Type (x)) X electricity unit rate cost. ………….. (B).
Investment Return Period (by Years) = (A) /
The Saudi Government adopts a policy of Energy Subsidizing by Subsidizing fuel products costs. The Government pays 70-75% of the fuel cost and that’s costing the kingdom amount of 163 billion Riyals per year as UN Energy Section Report in 2012 which constitutes 10% from the Gross National Product. This Report is recommending to review this policy to allow this support to go directly to the people really need it. If the Kingdom canceled this Energy Subsidizing policy, the Electrical unit price will be increased to 0.4 SR instead of 0.26 SR / kWh.
Regarding the Energy Subsidizing Effect, 4 Scenarios assumed in this study as following:
- S1: Same Electrical Unit Rate = 0.26 SR/kWh. (The current Cost of the Electrical Unit Rate will remain the same and the government will not change the Energy Subsidizing regulation in the
