What is being bought
Derry City and Strabane District Council wishes to engage a competent Energy Assessor to produce DEC’s (Display Energy Certificates) for all council buildings above 250M² to comply with the current EPB (Energy Performance in Buildings) Regulations. The council also requires that Energy Advisory Reports are produced by the Energy Assessor for all buildings included in this document in Year 1. The successful energy assessor must visit all sites before producing the Display Energy Certificate. Site visits must be co-ordinated with the client’s representative and evidence that the visit has been completed issued with the completed DEC. Site visits will not be required in Year 2 or year 3 unless the council confirms that there has been a significant change to the building. Your submission must be submitted via etendersNI, via this CFT. No other method of submissions will be accepted. Please refer to the CfT documents for further detail.
