Improving the energy efficiency of our existing building stock is attainable by upgrading the building envelope through carrying out various retrofit measures. The objective of this thesis is to evaluate the life-cycle cost implications of energy retrofits for existing buildings. Measures examined include improving insulation and air-tightness with overcladding strategies. The life-cycle costs of the upgrades are determined for an existing building and compared with model energy performance. A life-cycle cost evaluation for the building envelope upgrades is provided, together with the payback period and the projected return on investment (ROI) for two energy escalation rate scenarios. A costbenefit
matrix for various over-cladding strategies is provided to facilitate the evaluation of
each option. Further, this thesis presents a simplified ROI algorithm to enable owners,
architects and engineers to evaluate the cost-benefit of their building envelope retrofit options.
