Repair audit of a residential building

Objective

Indication of the scope of financial and material investment to improve the technical condition of a residential building with a 10% reduction in its heat demand.

Scope

For multi-family residential buildings, which began to be used before August 14, 1961, the Act on the Promotion of Thermomodernization and Renovation introduced the possibility of obtaining a repair bonus, which may be granted as a credit surcharge under the following conditions:

  1. Renovation and thermo-modernization work on the building (including replacement of windows in residential premises), which have not yet been repaired, thermo-modernization or European Union funds, can be subject to credit.
  2. Renovation fee is 20% of the loan used, but not more than 15% of the renovation cost.
  3. The condition of obtaining a bonus is to present a repair audit in the bank, which is prepared on the basis of the project-estimate documentation of planned repairs and thermo-modernization. Renovation fees are available to an investor who is a natural person, a residential community with a majority of natural persons, a housing cooperative or a social housing company. All improvements associated with thermo-modernization, including renovation projects, can be considered.

The renovation audit of a residential building includes:

  • Assessment of the current technical condition of the building and its installations
  • Determining the energy performance of a building
  • List of thermo-modernization improvements included in the renovation project, necessary to meet the requirement for reduction of the annual heat demand, and assessment of the achieved energy savings
  • Technical description of the renovation project to be implemented

 

Standard construction may be supplemented by the investor's cost estimates required to document the estimated repair costs. The audit meets the requirements set out in the “Regulation of 17 March 2009 on the detailed scope and forms of energy audit and the part of repair audit, the design of audit cards, as well as the algorithm for assessing the profitability of the thermal modernization project” and in the "Changing Regulation".

Methodology

  • PN-EN ISO 6946, "Building components and building elements. Heat resistance and heat transfer coefficient. Method of calculation".
  • PN-EN ISO 13370 "Thermal performance of buildings -- Heat transfer via the ground -- Calculation methods".
  • PN-EN ISO 14683 "Thermal bridges in building construction -- Linear thermal transmittance -- Simplified methods and default values".
  • PN-EN ISO 12831 "Heating systems in buildings. Method for calculation of the design heat load".

Reference

So far, we have developed over 150 renovation audits of buildings located in: Warsaw, Białystok, Łapy, Zambrów, Kolno, Ciechanów, Czosnow and Mińsk Mazowiecki.
