Thus, the instruments used for analysis of criteria can be seen in Table 2. Data collection was conducted in September during the spring season. The day in question was cloudy, and the weather conditions were suitable for the measurement of natural light and noise level, sub-criteria that had such information specified in the Brazilian performance standard.

The pre-occupancy assessment started at 8 am with arrival at the project site and assembly of the workstations. Figure 2 Floor plan of the analyzed apartment. The measurements followed the three defined collection cycles: morning, afternoon and early evening.

The data collected were compared with minimum performance requirements presented in the Brazilian performance standard. These instruments were chosen based on what the literature recommends to assess these criteria. The questionaire was conducted with two representatives of the building: the master builder and the project manager. The field inspection and project analysis were done on-site with the supervision of the master builder before the building was handed over to residents.

Data collection was performed on one day of the week. Rio de Janeiro, a. This standard refers to other specific standards that will also be considered in this research. The result of the analysis of each dimension is presented hereafter. Dimension 1 was analyzed using two instruments: inspection and questionaire.

As a result, dimension 1 presented a score of 17 out of As Table 3 details, some sub-criteria were not met. The technical team reviewed this item promptly. In addition, it shall also provide information on both innovative and conventional technical and material infrastructure compatible with the innovative building system.

In the studied case, the user manual does not present the LWF's relationship with other systems. Therefore, it is recommended that this information be incorporated into the user manual. It is known that LWF is a modular and flexible system, but as it is innovative, it must be made accessible to users, showing its correlations with other building systems, as an example.

Thumbnail Table 3 Dimension 1 evaluation. Dimension 2 was analyzed using measurement instruments. All criteria met the minimum performance values. For the thermal comfort criteria, three rooms of the apartment met the standard requirements, as shown in Table 4. The internal temperature was collected for 3 cycles using a thermo-hygrometer, as in the case of external temperature a datalogger was used. It is noteworthy that the research was conducted in spring, but, as there is no reference in the standard for this period, the comparison was made for the winter and summer seasons, which are the climatic extremes.

The thermal variation of the building was analyzed during the three collection cycles comparing the internal and external temperatures. Figures 3 , 4 and 5 show that internal temperatures remain at the center of the graphs, where the average temperatures of the day are.

In other words, when comparing the external variation line of the three cycles and the internal variation line, it is noted that the building is able to maintain the internal temperature more constant and milder than the external conditions.

Regarding acoustic comfort, data collection was performed with a portable sound level meter. In order to assess the difference between internal and external noises, measurements were made with both opened and closed openings doors and windows. Four measurements per cycle were made in each room, two with closed doors and openings and two with opened doors and windows. Figure 5 Internal and External Temperature Variation in the living room. ISO acoustics: field measurements of airborne and impact sound insulation and of service equipment sound: survey method.

Rio de Janeiro, Equation 1. In this case, 30 measurements were made in the same place of each room, considering the size of the room. Thumbnail Table 5 Analysis of acoustic comfort of the building. Although the results with the open windows did not meet the values proposed in the standard, comparing these values with the values measured outdoors without the acoustic protection of the building , it is clear that, even with the open windows, the building absorbed considerably the external noises, especially in relation to the dormitories, which should be the quietest environments.

In addition, the resident, by simply closing his windows, is able to adjust the acoustic performance of the building to comply with the values imposed by standard. It is noteworthy that the standard does not indicate a minimum number of readings to be taken in each room.

For this purpose, it was chosen to perform 10 readings over the 2 measurement cycles morning and afternoon. To calculate the FLD daylight factor , which is the standard item for on-site daylight measurements, one should also measure the natural lighting in an external point of the building in the shade.

To meet the minimum level of natural illumination performance by spot measurement, the FLD must be greater than or equal to 0. Bedrooms 1 and 2 were the rooms with the best results. Rio de Janeiro, b. As can be seen in Table 6 all rooms met the requirements. To perform the relative humidity evaluation, the Analysis Bio tool was used. In the tool, the climate file of the city in question was inserted so that its bioclimatic chart could be elaborated. To arrive at the assessment result, which indicates the comfort zone in which that environment is, temperature and humidity data must be correlated.

In this case, the dry bulb temperature was related to the relative humidity, represented by the red curves in Figure 6. Thus, it is then possible to locate points within the chart, checking in which bioclimatic zone each point is inserted.

As a result, all temperature and relative humidity intersection points are within the bioclimatic comfort zone, which means that in the evaluated rooms, the occupants are in environments that does not need to be cooled or heated. Regarding the humidity in the building, the data collection was done in two cycles morning and afternoon using as instrument a thermo-hygrometer. It is noted that a smaller variation in the relative humidity can positively influence the thermal comfort of the building since it does not require its occupant a very sudden adaptation to the environment.

Thumbnail Table 6 Natural ventilation in the studied building. Figure 6 Bioclimatic chart of the studied city. Dimension 3 was analyzed by questionaire and inspection. An environmental plan was not identified for this building, that is, guidelines that refer to the use of natural resources in a sustainable way, such as selective waste collection, rainwater harvesting and reuse, use of renewable energy, among others. The only guideline identified refers to proper disposal and maintenance with respect to sanitary sewage.

Considering that, the LWF system is seen as innovative in Latin American countries, and the importance of establishing an environmental plan to meet the Sustainable Development Goals SDGs is highlighted. Another point to be highlighted in this dimension is the building documentation. As the LWF is little known, with specific workmanship and materials needed for repairs, it is important that the user manual provide details for both repair and maintenance.

The manual should provide information necessary for the user to be able to purchase the established materials and perform proper repair and maintenance. Finally, in the evaluated building, the user manual, as well as the documents that refer to the system, were available to users. In dimension 4 all criteria were met. This dimension is comprised of the following structural durability, building maintenance and fence control criteria. Anexo A normativo.
