The study evaluates the cost‑optimality of Ireland’s new‑build energy performance standards under the EPBD Recast. Using representative residential and non‑residential building models, the authors assessed the effects of various energy‑efficiency measures and renewable technologies on primary energy demand and calculated lifecycle costs. Results show that the new‑build residential standards are cost‑optimal, whereas the non‑residential standards exceed the cost‑optimal range in primary energy demand.
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 [Council Directive 2010/31/EU]. 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 nonresidential 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.
