Key features
The Cost and Carbon module enables calculations under three cost categories: construction, utility, and lifecycle, and two LCA categories: One Click LCA integration and Embodied carbon reports. Additionally, a range of cost and carbon outputs are integrated within the parametric engine. DesignBuilder is the only tool to provide advanced cost-benefit design optimisation in an easy-to-use package.
Construction cost key features
- Costs are calculated using standard procedures with full flexibility in inputs and detailed tabular outputs.
- The construction cost tool is suitable for use with early design stage cost planning, life-cycle analysis and cost-benefit optimisation studies.
- Options are provided for NRM1 (RICS, UK) and UNIFORMAT II (ASTM, US and Canada) as well as a basic building only approach.
- Calculations are based on model surface areas and component cost rates along with the extra data required for the NRM1 and UNIFORMAT II standards.
- Output reports break down the costs according to the selected standard.
Utility cost key features
- Calculate building operational costs using standard procedures.
- Even the most complex utility tariff structures can be modelled using EnergyPlus with options to buy or sell (using a feed-in tariff) including flat charges, fixed rates and options for ratchets, qualifies and variables.
Life Cycle Cost key features
- Provides data on the cost of the building construction, operation and maintenance over its entire life cycle. This can help the design team to assess the cost of construction for design features against the corresponding impact on long-term utility and maintenance costs.
- Life cycle analysis applies standard procedures include consideration of:
- Recurring costs such as maintenance and repair
- Non-recurring costs such as end of life salvage
- Discount rates
- Tax
- Depreciation
- Inflation
- Price escalation
- Use adjustment
LCA features
DesignBuilder offers two ways to analyse the embodied carbon in your building design:
- Native integration to One Click LCA, the world’s leading building LCA and LCC platform, provides access to reports to satisfy the requirements of LEED, BREEAM Certification, DGNB, Green Star, NS3720, Taxonomy, and many others. A separate licence for One Click LCA is required.
- Built-in Embodied carbon reports can be displayed on the Cost and Carbon screen.
Packages
Cost is included in the Architectural Plus and all Engineering packages.
Dependencies
The Cost module can be used standalone for pure construction cost modelling, but the Simulation and HVAC modules are both required for calculating utility and life-cycle costs. For cost-benefit optimisation studies the Optimisation module is also required.
