A quick presentation from my 3rd year project in college based on a BIM model, utilizing the model as a tool to gauge the energy and carbon footprint for a large residential area.

2.  A measure of energy performance
 Suggestions for possible improvement
 Projections of cost and savings

3.  More precise predictions of building
performance,
 Boosted energy efficiency
 Thermal Analysis
 Carbon Footprint
 Cost savings
 Code and standards compliances
 Increased certainty

4.  4 Bedroom Council
House in GSDA
 9,008 units like this in
SDCC Portfolio
 Residential sector in
2008 accounted for
34% of primary energy
demand in thermal
energy.

5.  Compare BIM model produced Data
with Manual data
 Make an Environmental Evaluation
 Investigate Possible Improvements
 Analyze cost difference

6.  Exterior Walls HLR – 0.0272W/m^2K
 Roof HLR – 0.168W/m^2K
 Windows – 0.33W/m^2K
 Annual Fuel Cost (NG) – €508.208
/7,713kWh
 Annual Electricity Cost - €1197.31
/5508kWh
 C02 Output from NG- 1,588.87kg of C02

8.  Trouble shooting with restricted results
 Weather data
 Price data

9. IMAGES FROM BIM MODEL DESIGN PROCESS

10. WEATHER DATA FROM BIM MODEL

11.  With data that could be compared the
results were very reasonable

12.  143.84kWh/m2/yr
 C1 Rating
 Acceptable rating
For this type of
dwelling

13.  9,008 Similar Units
 Total Gas consumption = 69,478.704 MWh
 Total Cost in Euro of Gas = €4,749,089.664
annually. €192,456.01 in Carbon taxes
 Total Electrical consumption = 49,616.064 MWh
 Total Cost in Euro of Electricity =
€10,785,368.48 annually
 Total C02 Released = 14,312.54 Tonnes of C02
released annually solely by Natural Gas

14.  Some success but not the desired result
 Met all objectives except producing fully
functioning BIM
 There is room for improvement in the
building

15. This presentation is now finished
I am open to any questions you may have
