1.8 Life Cycle Costing
Purpose
Life Cycle Costing (LCC) is an important economic analysis used in the selection of alternatives that impact both pending and future costs. It compares initial investment options and identifies the least cost alternatives for a twenty year period. As applied to building design energy conservation measures, the process is mandated by law and is defined in the Code of Federal Regulations
(CFR), Title 10, Part 436, Subpart A: Program Rules of the Federal Energy Management Program.
The A/E shall contact local utility companies to determine available demand-side management programs and nocost assistance provided by these companies to designers and owners.
Applications
Basic applications of LCC are

These NIST materials define all required LCC methodologies used in GSA design applications.
It is recommended that the A/E obtain the BLCC so ware and update from NIST.
Procedures and Approach
The most e ective approach to LCC is to appropriately integrate it into the design process.
The building design evolves from general concepts to detailed analysis. LCC needs to follow the same approach paralleling the focus to the current level of detail study.
It is extremely important for the e ective development of the project that commitments are made and retained on the building systems, in a general sense, during the Conceptual Phase.
The building systems should be analyzed for appropriateness during the first stages of the Design Development Phase. A commitment on direction for the systems needs to be made at this time, and any further LCC studies focused on detail within each system. All LCC e ort should be completed in the Design Development Phase of the project.
The following practices are typically required when conducting LCC analyses for building design. They are listed here to address common concerns and frequently asked questions.
When defining alternatives for life cycle costing, an acceptable level of overall building services must be assured throughout the analysis period. Design alternatives must be compared against a baseline reference

3. What do the PCIB and PCIC indicate in terms of how much of the project has been accomplished to date?
For 15 years of that time he had responsibility for all aspects of the company's energy management activities (procurement, contract negotiation, budgeting, invoice auditing, energy efficiency initiatives, capital budget development/implementation,
We first held focus groups with a series of people involved in the commissioning, management, design and daily use of these kinds of buildings, because we needed to know what the clients expectations were, the design teams intentions and what was thought to be important among experienced users of such buildings.
This analysis is done assuming the benefits accrued in the year 2050. The costs are evaluated from the year 2011 – the proposed time of starting the project, while the benefits are calculated from the year 2020 – the expected time of launching the project. The estimated streams of benefits and costs occurring each year between 2011 and 2050 were discounted to their present value and summarized to calculate the benefit cost ratio.
For instance, Hawaii is being charged for things like renewable energy, and energy efficiency programs. However, a national energy expert Robert Thormeyer, a spokesman for the National Association of Regulatory Utility Commissioners, says it is not as easy to see whether Hawaii’s non-fuel charges are realistic because Hawaii has a unique isolated electric grids (Robert Thormeyer, 2015). It actually only currently cost Hawaiian Electric Company around 13.6 cents per kilowatt hour to generate electricity from its oil, but they charge residents 20-20 cents per kilowatt hour. In addition, a consumer is also paying an additional twelve dollars a month or one hundred forty-four dollars a year because of a program called decoupling. On top of that addition cost, consumers are charged an extra five dollars a month to support Hawaii’s energy efficiency and renewable energy programs. Therefore, consumers are paying addition fees without a choice because Hawaiian Electric Company is the only electric company in

Life Cycle Cost (LCC) is the total lifespan cost incurred by an organization in purchasing, installing, operating, maintaining, and disposing off any equipment used in daily operations of the firm. In regard to this, estimation of LCC encompasses using a particular approach in identifying and quantifying components of an LCC equation (Pehnt, 2006). The use of LCC as an assessment tool when selecting possible design alternatives results in the provision of a cost-effective solution within limits of available data. In addition, a standard LCC comprises initial and operation costs, installation and commissioning costs, energy costs as well as disposal costs among others.
The subsection (b) recommends that all the variations that are identified during the installation or the commissioning phase should be documented and approved if not identified earlier during the system designing phase. The recommendation also notifies that the purpose of this statement is not to cover for design flaws, the intention here is to identify issues that may appear because the conditions in the building may have altered from the time of designing, resulting in different working conditions.
According to the case study written by Jurek, Bras, Guldberg, D’Arcy, Oh, and Biller, energy costs were steadily rising and were predicted to continue this trend going into the future. At the same time, utility companies were beginning to implement Smart Grid technologies to increase the efficiency of energy distribution. One resulting program to emerge from
when building a system? Why not just build the system in whatever way appears to be “quick and easy”? What value is provided by using an “engineering” approach?

Inventory analysis is the data collection portion of a LCA and includes a quantified list of all inputs and outputs involving the entire life cycle of the concerned system. LCI involves estimating the energy and materials consumed by the system, the energy efficiency of the system’s components, and the emissions to air, land, and water by variant processes and components of the system. The process of data collection is the most time-consuming and resource-intensive step of the LCA. The reuse of data from other studies can simplify the work; however, assuring the data are representative is essential. LCI can be utilized to discover improvement opportunities and determine life cycle stages that present the most and least detrimental impacts [4].
When considering the preparation and development of a resource, cost is an important factor to consider. As well as monetary cost of the
