Life Cycle Costing & Life Cycle Analysis

Life cycle costing, carbon and environmental impact are increasingly important considerations for building owners and designers. HRS has deployed the latest analytical tools to help its clients make the most informed choices possible with regard to minimising whole life cost and environmental impact.

Using IMPACT-compliant software, HRS is able to provide life cycle costing and life cycle environmental impact analyses, attracting 3 credits under BREEAM criterion Man 02 and 2 innovation credits under Mat 01 (exclusive of the potential credits associated with the materials themselves). The IMPACT standard represents a step change in the accuracy and sophistication of life cycle analysis.

The analyses utilise HRS Services existing deployment of IES-VE software in conjunction with the BRE’s building component database. The approach is in line with BS EN 15978 2011 Assessment of environmental performance of buildings.

The life cycle costing can be built up from the client’s capital cost plan or developed from first principles. In both instances the analysis requires a 3D model to be imported as an IFC or NWC file from the client’s BIM model or built up by HRS from 2D drawings using ModelIT or Sketchup. Life cycle costs can be provided as real, nominal or discounted using a rate predetermined by the client.

The life cycle analysis is undertaken on the same base model and provides results in terms of both kgCO2 and BRE Enviropoints. The latter are based on 13 environmental indicators, including water extraction, human toxicity, mineral resource depletion, eutrophication, acidification and ozone depletion. The 60-year life cycle analysis, which reports on the whole life greenhouse gas emissions for each building element, will attract the 2 innovation credits under the BREEAM criterion Mat 01 and support up to 6 credits in the Mat 01 main building elements assessment, depending on building type.

The BRE material data used for the life cycle analysis is based on a publicly available methodology that has been peer-reviewed and conforms to ISO 14040, ISO 14044 and ISO 21930. At present the dataset is relevant only to the UK, but BRE is working with international partners to produce datasets for other regions.
