Cost Optimal Assessment of Buildings in Ireland Using Directive 2010/31/EU

 

Session 2, Paper 3, CIBSE ASHRAE Technical Symposium, Dublin, Ireland, 3-4 April 2014


This paper describes the first cost optimal assessment of national energy performance standards for buildings in Ireland undertaken in accordance with Article 5 of the Energy Performance of Buildings Directive (EPBD) Recast [i]. This paper focuses on new-build standards which are set out in Part L of the Building Regulations in Ireland. A set of representative residential and non-residential building models were selected. The impact on primary energy demand of a wide-range of energy efficiency measures and renewable technologies was evaluated for each building model and the corresponding lifecycle costs were calculated. The results show that the new-build residential standards in Ireland are in the cost optimal range, while the new-build non-residential standards deliver a greater primary energy demand than the cost-optimal range.
