This shows evidence of support by other literature (Evangelista et al., 2019)(Li Zhang et al., 2017)(Jayantha & Man, 2013)(Fesselmeyer, 2018)(Limao Zhang et al., 2018) in which the discussion reported that there are differences in prices if the property is green or GBI certified increased. The beta coefficient is 0.065 and this associates with the p value. Therefore, the model obviously shows there is a statistically significant change in value if the property is located at Timur Laut District if it is certified green. Out of the 18 control variables entered in the model, 13 variables were statistically significant. Further, it can be defining trough t values of the independent variables. CONCLUSION This paper analyses the green certificate effect on condominium price in Timur Laut District in Penang Island. The analysis uses database which comprises of a combination of several data including information from condominium transaction sale data. The data was compiled and extracted by NAPIC, and it is to be used for the purpose of valuation and research related to property. NAPIC is an organisation responsible to promote and provide information on property market in Malaysia. From the analysis done, it is found that green certification relatively gives an impact on property price. The percentage of premium if compared to non-certified building is about 6.5 per cent. The result is supported by a valuer who also estimated about 5-10 of price increment if condominium in Penang is green (Abdullah et al., 2018). Hence, the effect might vary according to the locality. Property market as well as green building should be explored differently in their local context. Even though most of the time green building is associated with high cost of construction, but the value of green is not only about cost. It represents the market, the demand, and the economics of the property. Value can be influenced by other factors. With more incentive, knowledge and promotion given by the government, green development can become the upcoming trend and demand. Specifically, the contributions of these findings can be explained in several contexts. First, this research adds “green” into the residential hedonic pricing literature especially from the perspective of local context. It is estimated that green can become a common consideration in the hedonic research paradigm. Next, this study encourages additional research on the effects of green development on housing sector. The results of this research indicated a positive and statistically significant premium for transactions with green as a housing feature. The findings from this study are parallel with most of green effect studies done previously. The biggest challenge here is to educate public on the awareness of sustainability and green development.
