Considering the growing importance of energy-efficient building methods, timber construction will play an increasingly important role in the future. In order to determine advantages and disadvantages of using wood as a leading constructional material, different construction types were compared: solid wood, wood-frame, concrete, and brick construction. To quantify the comparisons the analytic hierarchy process (AHP) was applied. AHP enables the inclusion of various parameters, including descriptive ones, in a mathematical model through which the importance of each construction criterion forming part of the system can be calculated in order to provide objective decisions for construction. Analysis revealed that the top ranked criteria in decision-making include embodied energy, construction cost and design. On comparing different construction types the wood-frame construction, which can have very low or negative carbon footprint, was considered as the most suitable option for public building. |
