Economic Evaluation of Building Investments

Introduction

Economic evaluation of building investments is a crucial process in estimating and costing structures. It involves assessing the economic viability and benefits of investing in a building project. By conducting economic evaluations, stakeholders can make informed decisions regarding the financial feasibility of a building investment.

Importance of Economic Evaluation of Building Investments

Economic evaluation helps in determining the financial viability of a building investment. It allows stakeholders to assess the potential costs, benefits, and returns associated with the project. By conducting a thorough economic evaluation, stakeholders can make informed decisions, minimize financial risks, and maximize returns on their investments.

Fundamentals of Economic Evaluation

Before diving into the methods and calculations involved in economic evaluation, it is essential to understand the fundamental concepts and principles.

Economic Methods for Evaluating Investments

Economic evaluation involves various methods to assess the financial viability of building investments. The key methods include cost-in-use analysis, benefit-to-cost analysis, and savings-to-investment ratios.

Cost-in-Use Analysis

Cost-in-use analysis is a method used to estimate the total costs associated with owning and operating a building over its useful life. It takes into account both the initial investment costs and the ongoing operational costs.

Definition and Calculation

Cost-in-use is calculated by summing up the initial investment costs and the present value of the expected future operational costs. The present value is calculated by discounting the future costs to their present value using an appropriate discount rate.

Factors to Consider

When conducting a cost-in-use analysis, several factors need to be considered, including:

• Initial construction costs
• Maintenance and repair costs
• Energy costs
• Insurance costs
• Property taxes
• Depreciation costs

Benefit-to-Cost Analysis

Benefit-to-cost analysis is a method used to compare the total benefits of a building investment to its total costs. It helps in determining whether the benefits outweigh the costs and if the investment is financially viable.

Definition and Calculation

Benefit-to-cost ratio is calculated by dividing the total benefits of the investment by the total costs. The benefits can include increased revenue, cost savings, improved efficiency, and other positive impacts.

Factors to Consider

When conducting a benefit-to-cost analysis, several factors need to be considered, including:

• Increased revenue
• Cost savings
• Improved efficiency
• Environmental benefits
• Social benefits

Savings-to-Investment Ratios

Savings-to-investment ratios measure the financial returns of a building investment by comparing the savings generated by the investment to the initial investment costs.

Definition and Calculation

Savings-to-investment ratio is calculated by dividing the annual savings generated by the investment by the initial investment costs.

Significance and Interpretation

A savings-to-investment ratio greater than 1 indicates that the investment generates more savings than the initial costs, making it financially viable.

Rate of Return and Payback Calculations

Rate of return and payback calculations are additional methods used to assess the financial viability of building investments.

Rate of Return

Rate of return measures the profitability of an investment by calculating the percentage return on the initial investment.

Definition and Calculation

Rate of return is calculated by dividing the net benefits of the investment by the initial investment costs and multiplying by 100 to get a percentage.

Payback Period

Payback period measures the time required for an investment to recover its initial costs through the generated savings or benefits.

Definition and Calculation

Payback period is calculated by dividing the initial investment costs by the annual savings generated by the investment.
