    A practical and simple methodology was developed to assist decision-makers in a renovation process. The methodology helps in setting priorities for renovation needs and to select the needed analysis methods, it enables cost-effectiveness studies and helps to choose proper renovation measures. The building physical, thermal comfort, indoor air quality, lighting and energy efficiency aspects are used when setting the target values and carrying out performance studies. Cost-effectiveness of the renovation can be evaluated by solving the technical present value of the building before and after renovation. Practical application of the methodology was presented using in a school building renovation project
