Research on factors that affect the value of residential buildings in the city of Denpasar has been done consisting of literature review, interviews with experts, data collection and statistical analysis. Obtained from literature review were 45 factors which then grouped into four, namely: land characteristics, environment, location, and building characteristics. Survey on 27 valuation expert respondents was done to obtain their perceptions on the factors, and then their perceptions were measured with Likert scale. The data were then statistically tested to determine its validity and reliability, after which factor analysis was performed to obtain factors that truly valid within its group. To further evaluate the dominant factor in each group, two hundred data of previously assessed residential buildings were collected and analyzed using multiple linear regression. Results showed that group of factors that affect the value of residential building the most is location (7.723) followed by environment (3.843), building characteristics (3,741) and land characteristics (3.253). Downtown area, road width, building area, and land area are the factor of location, environment, building characteristics, and land characteristics, respectively, that dominantly showed positive effect within its group. SUTET transmission, poor road conditions, poor physical condition of the house, and the land at road end "tusuk sate" dominantly showed negative impact within its group.

This chapter is a case study for the energy retrofit of an existing single-family residential building. The main assumption of the project was creating a model example for an energy retrofit with the aim of achieving the nZEB standard in existing residential building. The discussed building was built between the 1960s and the 1970s. The building was built using mixed technologies. The flooring on the ground floor was replaced; the foundation, external walls, and roof were thermally insulated. The windows and doors were replaced with higher parameter ones. Moreover, a modern biomass boiler was installed in the building along with the installation of a mechanical bidirectional ventilation unit with a heat recovery. Before the renovation, the building used about 133.4 GJ final energy for heating annually. After the renovation, the building uses about 8.89 GJ annually. The author describes all the stages of the renovation, the technical solutions, the calculations of economic and environmental benefits of the conducted renovations.

This article aims to describe the main manifestations found in the external area of ​​the residential building. The case study was performed through visual inspections of the structures, identifying the causes and proposing a correction method for these anomalies. Based on the literature review in books, articles, norms and laws, we sought to understand the definitions related to the inspection and preventive maintenance and corrective to the performance of the building, presenting the main points of interest using as reference the ABNT NBR 5674: 2012 - “Maintenance of buildings” and ABNT NBR 15575: 2013 “Performance of Housing Buildings”. After all the on-site survey was carried out, the intervention strategies were presented, ensuring that the facilities receive the necessary maintenance according to the needs of each environment. Therefore, it is concluded that the lack of maintenance in the residential building has caused discomfort in the residents and the expected performance for the building. Therefore, it is very important to have proper planning and conducting the building inspection throughout the building's life, and should have specialized and qualified professionals to perform preventive and corrective maintenance, so it will be possible to rescue its performance, ensuring durability, comfort and real estate appreciation.
