Using GIS in the Process of Creating a Green Building Index (GBI) Score for the Elements of the Roof

Inroduction

Green Building Index (GBI) is a certification system developed in Malaysia, it is used to assess the environmental performance of buildings in the country. The GBI was created by the Malaysia Green Building Confederation (MGBC) in 2009 as a national green building rating tool to promote sustainable building design and construction practices in Malaysia.

The GBI rating system assesses the environmental performance of a building based on six categories: Energy Efficiency and Conservation, Indoor Environmental Quality, Material and Resources, Site and Infrastructure, Water Efficiency and Innovation in Design. Buildings are evaluated based on specific criteria within each category, and are assigned a score. To achieve GBI certification, a building must meet the minimum requirements set out by the GBI rating system.

The benefits of GBI certification include:

• Reduced energy and water consumption, which can lead to cost savings for building owners and occupants.
• Improved indoor air quality, which can lead to better health and productivity for building occupants.
• Increased use of sustainable materials and resources, which can lead to reduced environmental impact.
• Enhanced site and infrastructure, which can lead to a more sustainable and livable environment.
• Encourage innovation in design, which can lead to better buildings that are more efficient, healthier and sustainable.
• It also provides a benchmark for building performance and encourages continuous improvement.
• It can also be used as a marketing tool for building owners and developers to promote their building’s environmental performance.

The Six Criteria of GBI

1. Energy Efficiency and Conservation: This category assesses the building’s energy efficiency and energy conservation measures. This includes evaluating the building’s thermal insulation, reflectivity, solar panels, and energy-efficient lighting and appliances. The criteria also assess the building’s heating, ventilation, and air conditioning (HVAC) systems to ensure they are energy-efficient and properly maintained.
2. Indoor Environmental Quality: This category assesses the indoor air quality of the building, including the levels of pollutants, temperature, humidity, and lighting. The criteria also evaluate the building’s acoustics, and assess the use of low-emitting materials to improve the indoor air quality.
3. Material and Resources: This category assesses the use of sustainable materials and resources in the building’s construction and operation. This includes evaluating the use of recycled materials, the durability of the building’s materials, and the building’s waste management systems.
4. Site and Infrastructure: This category assesses the building’s impact on its surrounding site and infrastructure. This includes evaluating the building’s water management systems, the use of green spaces, and the building’s impact on the local ecosystem.
5. Water Efficiency: This category assesses the building’s water efficiency and conservation measures. This includes evaluating the building’s plumbing fixtures, irrigation systems, and the use of greywater and rainwater harvesting systems.
6. Innovation in Design: This category recognizes buildings that go beyond the minimum requirements of the GBI rating system and innovate in the areas of environmental performance, sustainability, and design.

The evaluation of a building’s environmental performance based on these criteria is carried out by professional GBI certifiers, who will conduct on-site inspections, analyze material, conduct energy modeling, assess indoor air quality, waste reduction, water conservation, and building management. Based on the building’s performance in each of the six categories, a score is assigned and the building is rated. To achieve GBI certification, a building must meet the minimum requirements set out by the GBI rating system. The GBI certification process is not only beneficial for the environment but also for the building’s occupants, it makes the building more energy efficient, healthier, and sustainable.

Procedures to Get Certified

The procedures to get a building certified under the Green Building Index (GBI) certification system involve the following steps:

1. Pre-Registration: Building owners or developers interested in obtaining GBI certification for their building must first pre-register their building with the Malaysia Green Building Confederation (MGBC), the organization responsible for administering the GBI certification process.
2. Application: After pre-registration, the building owner or developer must complete an application for GBI certification and submit it to the MGBC. The application includes detailed information about the building’s design, construction, and operation, as well as information about the building’s environmental performance.
3. Documentation: The building owner or developer must also submit a set of documents that provide evidence of the building’s compliance with the GBI criteria. These documents include design and construction drawings, energy and water consumption data, and other relevant information.
4. On-site Inspection: Once the application and supporting documents have been reviewed, a GBI certifier will conduct an on-site inspection of the building to verify the information provided in the application and to ensure that the building meets the GBI criteria.
5. Scoring and Rating: Based on the building’s performance in each of the six categories, a score is assigned and the building is rated. To achieve GBI certification, a building must meet the minimum requirements set out by the GBI rating system.
6. Certification: Once the building has been certified, the building owner or developer will receive a GBI certificate and a GBI rating plaque that can be displayed on the building. GBI certification is valid for 3 years, after which the building must be re-certified to maintain its GBI certification status.

It should be noted that the GBI certification process can be a complex and time-consuming process, and it requires a significant amount of documentation and evidence to demonstrate compliance with the GBI criteria. Therefore, it is recommended that building owners or developers work with a GBI certifier or consultant to guide them through the certification process.

Green Building Index (GBI) is a certification system developed by the Malaysia Green Building Confederation (MGBC) specifically for buildings in Malaysia. It is not possible for someone to create their own version of GBI as it is a proprietary system owned by MGBC. However, other countries may have similar certification systems for green buildings, such as LEED in the United States and BREEAM in the United Kingdom.

Building owners or developers who are interested in assessing the environmental performance of their building can look into these other certification systems, or they can develop their own internal rating system based on their own sustainability goals and performance metrics. However, it’s worth noting that these internal rating systems may not be recognized or accepted by regulatory authorities or the industry at large.

It is also worth noting that GBI is not a mandatory certification, it is voluntary. Building owners or developers can choose not to participate in the GBI certification process, or they can choose to implement sustainable building practices without obtaining GBI certification.

Can You Create Your Own Index?

If someone wants to develop their own green building index, they should consider the following steps:

1. Research existing green building certification systems and standards, such as LEED, BREEAM, and GBI, to understand the criteria and standards that are commonly used to assess the environmental performance of buildings.
2. Define the scope and goals of the index, such as which types of buildings will be covered, and what environmental performance metrics will be used to evaluate buildings.
3. Develop the criteria and standards for the index, based on the research and scope of the index. These should be specific, measurable, and relevant to the environmental performance of buildings.
4. Develop a scoring system for the index, which will be used to assign a rating or score to buildings based on their performance in each of the criteria.
5. Develop a process for assessing buildings against the criteria and standards, including guidelines for data collection, documentation, and on-site inspections.
6. Develop a process for certifying buildings that meet the criteria and standards, including guidelines for issuing certificates and plaques.
7. Develop a process for maintaining and updating the index over time, to ensure that it remains relevant and up-to-date with the latest sustainable building practices.

It’s worth noting that creating a green building index is a complex and time-consuming process, and it requires a significant amount of expertise in the field of sustainable building design and construction. Therefore, it is recommended that someone who wants to develop their own green building index work with a team of experts, such as architects, engineers, and sustainability consultants, who can provide guidance and support throughout the process.

Types of Data Needed to Create Index

The data needed to develop a green building index will depend on the specific criteria and standards that are used in the index. However, generally speaking, the following types of data may be needed:

1. Building design and construction data: This may include information on the building’s size, layout, orientation, materials, and systems, as well as details on the building’s energy and water efficiency, indoor air quality, and the use of sustainable materials.
2. Building performance data: This may include data on the building’s energy and water consumption, as well as data on the indoor environment, such as temperature, humidity, and lighting levels.
3. Site data: This may include data on the building’s location, such as the climate, topography, and vegetation, as well as data on the site’s water resources, such as groundwater and surface water.
4. Operation and maintenance data: This may include data on the building’s operation and maintenance, such as information on the building’s cleaning and waste management practices, as well as data on the building’s maintenance and repair history.
5. Other data: this may include data from GIS, remote sensing, or aerial images to be used as an additional assessment tool.

It is important to note that the data collection process should be thorough and accurate to ensure that the building is evaluated fairly. Also, having a clear data management system to store and organize the data is important to ensure easy access and retrieval of the data.

Spatial Element

The Green Building Index (GBI) certification system for buildings in Malaysia has six main criteria: energy efficiency, indoor environmental quality, water efficiency, materials and resources, land use and ecology, and innovation. The spatial element of the criteria is mainly found in the land use and ecology criteria.

1. Land Use and Ecology: This criteria evaluate a building’s site, landscape, and its impact on the surrounding environment. It looks at the building’s overall site design, including site planning, stormwater management, and the preservation of natural habitats and biodiversity. Additionally, it evaluates the use of green roofs, green walls, and other features that can provide ecological benefits.
2. Materials and Resources: This criteria evaluates the building’s use of sustainable materials and resources, including the use of recycled materials, the sourcing of materials from local suppliers, and the use of renewable energy sources. It also considers the building’s waste management practices, including recycling and composting, and the building’s overall environmental impact.
3. Energy Efficiency: This criteria evaluates the building’s energy performance, including its heating, cooling, lighting, and hot water systems, as well as the building’s overall energy consumption. It also evaluates the building’s use of renewable energy sources, such as solar and wind power, and its potential for energy conservation.
4. Water Efficiency: This criteria evaluates the building’s water performance, including its use of water-efficient fixtures and appliances, as well as the building’s overall water consumption. It also evaluates the building’s use of alternative water sources, such as rainwater harvesting and greywater recycling, and its potential for water conservation.
5. Indoor Environmental Quality: This criteria evaluates the building’s indoor environment, including its air quality, thermal comfort, and acoustics. It also evaluates the building’s use of natural light, as well as its overall design and layout, to promote the well-being of the building’s occupants.
6. Innovation: This criteria evaluates the building’s overall environmental performance, including its use of cutting-edge technologies and practices, as well as its potential for future innovation. It also evaluates the building’s overall environmental impact, including its carbon footprint and overall sustainability.

It’s worth noting that GBI certification system is continuously evolving, and it is subject to change based on the latest technology, research and development.

Roof as One of the Element

Roof can be one of the elements considered in the Green Building Index (GBI) certification system. For example, the land use and ecology criteria in GBI evaluates the building’s site, landscape, and its impact on the surrounding environment. It looks at the building’s overall site design, including site planning, stormwater management, and the preservation of natural habitats and biodiversity. Additionally, it evaluates the use of green roofs, green walls, and other features that can provide ecological benefits.

A green roof, also known as a living roof, is a roof covered with vegetation, which can provide many benefits such as reducing heat island effect, improving air quality, reducing the building’s energy consumption, and preserving biodiversity. The green roof can also help to manage stormwater runoff, reduce the building’s environmental impact, and promote the well-being of the building’s occupants.

In addition to that, the materials and resources criteria in GBI evaluates the building’s use of sustainable materials and resources, including the use of recycled materials, the sourcing of materials from local suppliers, and the use of renewable energy sources. The roofing materials used on the building can be a part of this evaluation, for example, the use of cool roofing materials can reduce the building’s energy consumption and its environmental impact.

In conclusion, roof can be considered as an element in GBI certification system, as it can affect the building’s environmental impact, energy consumption and the overall well-being of the building’s occupants.

Using Remote Sensing and uav images

Remote sensing and unmanned aerial vehicle (UAV) images can be used to detect elements of the roof in a building, such as the type of roofing material and the condition of the roof.

Remote sensing technology, such as satellite imagery and aerial photography, can be used to obtain high-resolution images of buildings and their surrounding areas. These images can be used to detect the type of roofing material used on a building, such as asphalt shingles, metal roofing, or green roofs. They can also be used to detect the condition of the roof, such as whether it is in good condition or showing signs of wear and tear.

UAVs, also known as drones, can be used to obtain high-resolution images of building roofs and their surrounding areas. These images can be used to detect the type of roofing material used on a building, such as asphalt shingles, metal roofing, or green roofs. They can also be used to detect the condition of the roof, such as whether it is in good condition or showing signs of wear and tear. UAVs can also be used to obtain images of hard-to-reach areas of the roof, such as skylights or rooftop mechanical equipment.

However, it’s worth noting that remote sensing and UAV images alone may not be sufficient to evaluate all elements of the roof and the building, as it’s important to conduct a physical inspection of the building to validate the data and information obtained through remote sensing and UAV images.

To use remote sensing and UAV images to detect elements of the roof in a building, the following steps can be taken:

1. Obtain high-resolution images of the building and its surrounding area using remote sensing technology such as satellite imagery or aerial photography, or using UAVs.
2. Process the images to extract relevant information, such as the type of roofing material and the condition of the roof. This can be done using image processing software, such as ENVI or ArcGIS.
3. Analyze the images to detect the type of roofing material used on the building. This can be done by comparing the images to a library of roofing materials, such as the National Roofing Contractors Association’s (NRCA) roofing manual.
4. Analyze the images to detect the condition of the roof. This can be done by looking for signs of wear and tear, such as missing or damaged shingles, and by comparing the images to a library of roofing materials.
5. Cross-reference the data obtained from the remote sensing and UAV images with the data obtained from a physical inspection of the building. This is important to validate the data and information obtained from the remote sensing and UAV images, as well as to detect any discrepancies or errors in the data.
6. Use the data and information obtained from the remote sensing and UAV images, along with the data obtained from the physical inspection of the building, to evaluate the building’s roof, and to make recommendations for repairs, maintenance, or upgrades as needed.

It’s worth noting that remote sensing and UAV images alone may not be sufficient to evaluate all elements of the roof and the building, as it’s important to conduct a physical inspection of the building to validate the data and information obtained through remote sensing and UAV images.
