Building Retrofit Diary: Main University Building Vilnius, Lithuania

This diary consists of quarterly reports of the status of the demonstration site written by the responsible demonstration partner.
 
General Overview

Description of the renovation and its purpose Having in mind that the building is in use more than thirty years, it is suggested the following: to correct the operation of renovated thermal unit and complement a part of its automatics, still better effect should be reached. Reduction of glazed areas with the warmed up shields, renovation of facades as well as change of current windows will have a very important impact on energy saving. Besides, with partial renovation of illumination and electrical engineering it is also unavoidable that people working inside the building get interrupted. The efficiency level of the main VGTU building's refurbishment depends on a great many of factors, including: cost of refurbishment, annual fuel economy after refurbishment, tentative pay-back
time, harmfulness to health of the materials used, aesthetics, maintenance properties, functionality, comfort, sound insulation and longevity, etc. Solutions of an alternative character allow for a more rational and realistic assessment of economic, ecological, legislative, climatic, social conditions, traditions and for better satisfaction of architectural, comfort, functional, maintenance and other customer requirements. They also enable one to cut down on refurbishment costs. The developed Multiple Criteria Decision Support System for Building Refurbishment will allow to assess alternative designs of the main VGTU building's refurbishment, multiple criteria analysis and make the selection of the most efficient versions, etc.

Status up to today
In the process of renovation the balance between the three components building envelope, heating and ventilation must be kept. Because of the financial shortages attention was not paid to the third renovation component, i.e. ventilation and in consequence the ventilation system was not foreseen to be refurbished. Now the authorities of university are planning to retrofit the ventilation system.
