1 Comparing Green Structures with Different Thermal Efficiency Designs By: Mohammed I Daher

2 Aims and Objectives:  Aims :  Provide an understanding of the importance of thermal insulation and its benefits.  Objectives:  Determine the payback period and return on investment for investing in different thermal insulation designs and heating systems.  Determine the Carbon footprints of different cases of thermal insulation and heating systems.

3 Methodology: Case 1:  No thermal insulation (traditional building)  U-Values: 3.34 W/m 2.k (walls), 2.44 W/m 2.k Case 2:  Jordanian thermal insulation code 2002  U-Values: 1.8 W/m 2.k (walls), 1.0 W/m 2.k Case 3:  Jordanian thermal insulation code 2009  U-Values: 1.6 W/m 2.k (walls), 0.55 W/m 2.k  High efficiency thermal insulation (Al- Kamaleyah Residence) combined with solar heating  U-Values: 1.3 W/m 2.k (walls), 0.2 W/m 2.k Case 4:

4 Case 1:  Total mechanical heating cost: JD  Annual fuel cost: JD/year  Carbon footprint: Tons of CO 2 annually  Thermal insulation cost: 2135 JD Case 2:  Total mechanical heating cost: JD  Annual fuel cost: JD/year  Carbon footprint: 26 Tons of CO 2 annually  Thermal insulation cost: Zero

5 Case 3:  Total solar heating cost: JD  Annual fuel cost: Zero  Carbon footprint: Zero CO 2 emissions  Thermal insulation cost: JD Case 4:  Total mechanical heating cost: 9139 JD  Annual fuel cost: JD/year  Carbon footprint: Tons of CO 2 annually  Thermal insulation cost: 3355

6 Total investment cost

7 Proper thermal insulation reduces the fuel cost needed to maintain thermal comfort in buildings.

8 Payback period:  Payback period for investing in case 3 over case 2: (12494 – 12205) / ( – ) = 0.8 years = 10 months  Payback period for investing in case 4 over case 2: ( – 12205) / ( – zero) = 1.4 years = 17 months  Payback period for investing in case 4 over case 3: ( – 12494) / ( – zero) = 1.52 years = 19 months

9 Return on Investment: Total investment and operation cost (JD) Year Case

10 Return on Investment:

11 Conclusions:  Investing in high efficiency thermal insulation and solar heating saves operational cost on the long run and eliminates CO 2 emissions.  Investing in high efficiency thermal insulation and solar heating can have a payback period as short as 17 months and return on investment as high as 49.64% over 5 years.  Investing in thermal insulation can result in savings on initial investment cost as lower capacity mechanical heating would be required.
