Renewable Heat Obligation (RHO) that some portion of heat energy used in newly constructed buildings with minimum gross area should be supplied using new and renewable energy sources. The Korean Government is considering the introduction of the RHO policy, in the newly-built building with should be supplied heat using new and renewable energy sources 20% by 2020. Extended application of RHO gives the public two benefits compared to using fossil fuels: decreasing reliance on energy from overseas; and reducing greenhouse gases and air pollutants. In spite of above advantages, it has difficulty to apply RHO in the new buildings. Because supply renewable heat in the new building raises construction cost. Nevertheless of different positions of energy- and construction- authorities, there is social consensus on the necessity of RHO. Thus the quantitative information for benefits from applying RHO is needed to support decision-makers. This study attempts to evaluate the economic value of expanding supply of renewable heat in the new buildings. We took the economic value as additional willingness to pay (WTP) of annual income tax. The WTP data were obtained from a one-and-one-half-bounded dichotomous choice contingent valuation survey of 600 households. We applied a spike model to treat the WTP data with zero observations. The yearly mean WTP was computed as KRW 5,753 (USD 4.7) per household for the next 10 years, which is also statistically meaningful at the 1% level. Expanding the value to the national population gives us KRW 106.2 billion (USD 93.0 million) per year. |
