The present invention consists of features and a combination of parts hereinafter fully described and illustrated in the accompanying drawings, it being understood that various changes in the details may be made without departing from the scope of the invention or sacrificing any of the advantages of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
To further clarify various aspects of some embodiments of the present invention, a more particular description of the invention will be rendered by references to specific embodiments thereof, which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the accompanying drawings in which:
Figure 1 is a schematic that shows a network for data and processing to estimate a building life cycle cost.
Figure 2 is a flowchart of the procedures for estimating the building life cycle cost.
DETAILED DESCRD7TION OF THE INVENTION
This invention relates to system and method directed to carry out building life cycle cost analysis.
An embodiment of the present invention shown in Figure 1 discloses a computer processor (100) compiles and calculates correlations based on input data related to a user's requirements. A database (103) supplies and stores information regarding a building, such as reference data of an initial capital cost, a financial cost; an operation cost; a maintenance and replacement cost and a Salvage cost. A server (101) receives a processed and stored data from the processor (100) and the database (103), respectively. A terminal (102) at the user's retail outlet can access the server (101). The user can manually provide an input data, or with particular selections, such as generic configurations, the input data can be provided automatically from the database (103).
Referring to figure 2, the procedures of the embodiment begin at start (200) and proceed to acquire at least one purpose of carrying out life cycle cost analysis of a building (201). The examples of the purposes are to determine the most optimum life cycle cost amongst mutually exclusive alternatives; to advise clients and building owners to emphasize on a total ownership costs and to help them to ascertain their financial capability in operating and mamtaining the building over an anticipated study life; to identify areas where the cost changes accordingly due to the adjustment in the building design, working practices, use of new plant, use of different maintenance analysis or to provide inputs to clients and buUding owners in constructing energy management strategies and sustainable management approaches to reduce building wastes and increase energy savings. Next, the procedure continues with states to state the building categorization and to provide building project information (202). In this step, the user also needs to indicate whether the building is certified as a Green Building Index (GBI) and qualified to obtain the GBI financial incentives from the Government. It should be understood that other construction industry accepted rating system such as GreenPass, pHJKR, GreenRe also can be used in the present invention.
The user is then deciding the scope (203) by choosing a level of life cycle cost study and a level of design process on which life cycle cost is decided to be based. The choices of the level of life cycle cost study are strategic level such as maintainability and internal environment, comfort and use; system level such as energy, wall, floors, ceiling finishes, roofing, roofing finishes; or detailed level such as steelwork, concrete, electrical, mechanical, paint type, lifts, escalators, plumbing, glazing. The level of design process is including inception, feasibility, outline proposal, scheme design, detailed design, production information and bill quantities.
A mathematical cost model, study life and discount rate is input at step (205, 206, 207). The user needs to decide an appropriate mathematical cost model such as Net Present Value model either in single present value or uniform present value to estimate the total cost of the building. The basic requirements of the Net Present Value model estimation are the study life and discount rate. Thus, the user should determine the most appropriate study life and discount rate that should be applied in the life cycle cost analysis after taking into account some determinant factors provided from the database (103).
A plurality of cost components of the building such as initial capital costs, operation costs, maintenance and replacement costs, financial costs and salvage costs is stated by the user at step (207) of determining the scope of costs. Examples of the initial capital costs are including land acquisition cost, construction works costs (i.e. substructure, superstructure, finishes, fittings, services installation, external works, preliminaries, contingency including risk allowances, and contractor's design fees,), other construction related costs (i.e. professional services fees, marketing costs, decanting, infrastructure charges, infrastructure adoption and maintenance cost, highway cost, utility charges, licenses and permits, planning application and building regulation fees, party wall cost, rights to light cost building regulation fees, party wall cost, rights to light cost, client's design development, financing cost, insurance, contingency including risk allowances), and client definable costs (e.g. cost incur to make value added on the building), landscaping cost. Examples of the operation costs are including utilities costs, insurance, service costs, administration costs, security costs, cleaning costs, local and statutory charges in connection with the building operation. Examples of the maintenance and replacement costs are the costs of regular custodial care and repair, annual maintenance contracts, maintenance management, adaptation or refurbishment, redecoration, and salaries of facility staff performing maintenance tasks, repairs and replacement of minor components. Examples of the financial costs are discount rates, inflation rates, interest rates and taxes. Examples of the salvage costs are a cost, or gain, of getting the rid of assets after use at the end of study life (residual value, demolition cost, transferring cost, disposal inspection cost). In addition, the user needs to state all the assumptions being made and the rationales of using them in the life cycle cost analysis.
Next, the procedure proceeds to determine preferred data of the cost components in terms of available, accessible, currency and reliable (208). The available degree is divided into highly available available and hmited. The data in highly available is freely published online and unrestricted for public use while the available data is available for life cycle cost analysis but need to subscribe from the subscriber-base information services provided library. For limited availability data, the data is confined by firms or organization in the library. The accessibility degree is divided into three: highly accessible, accessible and limited. The highly accessible data is freely published online and unrestricted for public use; accessible data is needed to subscribe from a subscribe-base information services provided; limited data is limited for public access. The current degree is divided into three: very current, current and less current. The very current data is very often updated either on weekly, monthly, quarterly or yearly basis; current data is updated once in a couple years or more less than five years period; less current is data updated once in a period of more than five years. The reliability degree is divided into very reliable; reliable and less reliable. The very reliable data is the most structured data that are formed in detail completeness and adequate and compatible to be used as inputs into the process of generating life cycle cost analysis; reliable data is consistent and comparable to the actual value which arrived from similar and repetitive methods under, the same research condition; less reliable data is incomplete, inadequate and incompatible which produce output which is not consistent overtime.
The step in (209) facilitates the user to identify available and accessible of the cost components based on reference cost component stored in the database (103). The step (210) facilitates the user to identify current level of the cost components based on updated reference cost component in current construction industry, which suitable to be used as inputs for life cycle cost analysis. The updated reference cost component is updated using either discount formulas or Interest table. A network can provide for the database (103) to keep updating its data. The step (211) provides several steps that can facilitate the user to check and improve cost data to ensure the reliability of input in the analysis can be achieved.
The step (212) is considered complete if the cost components which have gone through the previous steps are satisfactory (213) to be used as inputs for producing reliable outputs for the analysis. However, if the cost data is unsatisfactory to be used (214) as reliable inputs for life cycle cost, the user should restart the process and analyse feedbacks received as bases for further improvement on the quality data input requirements process (216).
The present invention may be embodied in other specific forms without departing from its essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore indicated by the appended claims rather than by the foregoing description. All changes, which come within the -meaning and range of equivalency of the claims, are to be embraced within their scope.
