Automate your construction life-cycle costing & carbon assessment

All material data include modifications for different regions related to labour costs and cost indexes. Datasets for material costs are structured to consider the cost of materials installed, and they include a labour cost component. The cost data is available for all main construction materials in the One Click LCA database. Its accuracy will depend on variances in type, specification, and method of construction. The database production process has used various cost databases, including the Neubau Baupreise Kompakt; Statistische Baupreise für Positionen mit Kurzttexten (BKI) (2017) and the Spon’s Architects’ and Builders’ Price Book (AECOM) (2017).

Labour costs are based on the International Labour Organisation, wage report 2016. These costs are the total costs paid for labour by the party contracting labour including all applicable overheads.

Maintenance costs are based on regional labour costs and labour intensity of various maintenance operations. The production process has considered various sources, including Whitestone Facility Operations Cost Reference, International (2014) and Whitestone Facility Maintenance and Repair Cost Reference, International (2013) and include modifications for different regions related to labour costs, processes, and cost indexes. End-of-life costs are calculated based on the capital costs. The end-of-life is a percentage of capital costs, which is based on averaged projects. 

A0-A5 pre-construction and before use stage: Costs of purchase or rental costs (costs of the site); costs of building products; costs related to the transport between factory and site; project feasibility, planning, design, engineering and construction costs, incl. permissions, commissioning and handover; site clearance and landscaping (e.g. lawn, trees, and similar within the curtilage and other external works costs; subsidies and incentives (e.g. incomes related to renewable energy).

B1-B3 operation and maintenance costs: Building-related facility management costs (e.g. regular cleaning, insurance, security, fire inspection, and similar costs); repair costs; ground maintenance; redecoration.

B4-B5 replacement / refurbishment: Planned adaptation or refurbishment (incl. infrastructure, fitting out and commissioning, validation and handover); replacement of major systems and components (incl. associated design and project management).

B6 operational energy use: Energy costs (incl. fuel and electricity for heating, cooling, power, domestic hot water, and lighting, as per the EU’s Energy Performance of Buildings Directive or EPBD).

B7 operational water use: Water-related costs (e.g. rates, local charges, environmental taxes).

C1-C4 deconstruction: Demolition costs; transport costs associated with deconstruction and disposal; fees & taxes (e.g. landfilling); waste processing costs.

With One Click LCA's life-cycle costing tool, you can calculate ‘life-cycle cost, discounted’ and ‘life-cycle cost, nominal’ (undiscounted, includes inflation). Both result categories account for the same calculation parameters (the same set inflation rates). However, there is one major difference.

The ‘life-cycle cost, discounted’ does not consider inflation, and the value of the chosen currency is estimated to be the same over the entire set calculation period. The ‘life-cycle cost, nominal’ results include inflation, meaning that the set currency will not have the same value over the entire calculation period, often resulting in a higher total.
