JM Klima s.r.o. offers performance of energy audits of buildings, production premises and houses.

The energy audit is often required as an attachment to the applications for subsidy of a project, e.g. for thermal insulation or another manner of reducing energy intensity of a building or for installation of a renewable energy source. It also serves as a document for banks for the assessment of a loan application intended for implementation of energy investment. The energy audit is also recommended in case you plan a building renovation.

Under Section 9 of Act No. 406/2000 Coll. and Decree No. 213/2001 Coll., amended by Decree No. 425/2004 Coll., the energy audit must comprise:

  • evaluation of the current state of the building and of energy management
  • amount of technically feasible energy saving
  • proposals of energy saving measures and justification of the recommended option, including economic evaluation
  • assessment of potential use of renewable sources of energy for the subject of the audit, including economic evaluation
  • final opinion of the energy auditor
