This article considers building renovations, which are presented in a building building view as Planned renovations. # Building renovation view Building renovation view considers in three parts: * Overview * Past & future renovations * Controls ### Overview Renovation overview shows a graph displaying last five year and future ten years renovation costs. ### Past & future renovations Past & future renovations table contains the most recent and near future renovations for the building. Renovations are either **Assumed** or **Planned**. A renovation year followed by an asterisk denotes the renovation is statistically Assumed, and the absence of an asterisk denotes the renovation is of user origin, that is, Planned. Moreover, a description and price estimate are provided for each renovation. The control icons pen and bin are for editing and deleting a renovation. For more information about editing, please refer to Section Add a new renovation. We recommend you to fill in the renovations table as thoroughly as possible to gain the most up-to-date and accurate SkenarioLabs analytics. || **Assumed renovations** are based on Skenarios data analysis of similar properties and construction components. They are not always necessary needed but will give user understanding of potential renovation needs in the future. Skenarios updates assumed renovations periodically when service models improve over the course of time. An Assumed renovation becomes Planned renovation if updated by a user. Adding a part change also generates relevant other assumed maintenance renovations for the part. Also, removing a part change will also cancel part's assumed renovations. || **Planned renovation**s are improvements intended by the user. Skenarios will consider them when updating analysis for assumed repairs, but won't change them. ### Controls Controls contain a button for adding a new renovation and filtering assumed renovations. Filtering affect both Overview and Renovation list. To add a new renovation, click Add renovation -button, which opens a new window. # Add a new renovation By clicking Add renovation, a new window opens and it contains controls for adding a new renovation.
