Abstract—It is well acknowledged that construction industry suffers from drawbacks of poor construction implementation. Airtightness for instance, is one of the prominent factors which contribute to excessive building energy consumption, in the operation phase of the project. The aim of this research is to demonstrate the disadvantages of low-quality construction implementation from the airtightness point of view, in the early design stage by integrating Building Information Modeling and thermal performance modeling, taking conventional detached single-family dwellings in Cyprus as the case study. Different rates of air change per hour in the insulated and uninsulated residences were considered and, as a result annual energy consumption of an insulated residence which ACH rate was 2.5 – that accounts for poor implementation - computed to be roughly the same as a similar uninsulated case which ACH rate was 0.25 (29942 kWh compared to 30075 kWh). In addition, cooling load demand remained steady at approximately 25000 and 20000 kWh for uninsulated and insulated cases respectively, under the effect of altering ACH rate.
Index Terms—Airtightness, building information modeling, construction implementation quality, ecotect, revit, thermal simulation.
