  • Supervision of sustainable practices integration: The consultant ensures that all stakeholders understand and apply best practices in sustainable construction.

  • Performance monitoring and adjustments: They evaluate building performance and recommend adjustments to optimize energy consumption and minimize environmental impact while ensuring compliance with various project requirements.

To fulfill their responsibilities, a green building consultant must perform specific tasks:

  1. Educate the client on latest technologies and best environmental practices: The consultant provides specialized expertise and up-to-date information on best environmental practices and sustainable technologies. This knowledge allows clients to make informed decisions to maximize energy efficiency and minimize the ecological impact of their projects.

  2. Anticipate project issues and propose solutions: They identify sustainability-related issues that need to be addressed in the project, ensuring that the most significant challenges affecting the building's performance and environmental compliance are tackled.

  3. Conduct a precise project diagnosis: The consultant conducts a comprehensive diagnosis that includes identifying problems, collecting and analyzing relevant information to assess environmental impacts and opportunities for energy efficiency improvement.

  4. Formulate relevant recommendations: Based on the diagnosis, the green building consultant synthesizes findings and makes strategic recommendations to guide the project towards best sustainability practices. These recommendations are based on rigorous analysis and tailored to the specific needs of the project.

  5. Implement strategies: In addition to making recommendations, the consultant is often involved in implementing solutions. This can include assisting in selecting sustainable materials, designing efficient energy systems, and integrating innovative technologies.

  6. Build consensus and commitment within the project: The consultant works to build consensus among all project stakeholders, facilitating engagement around sustainability goals. This includes effectively communicating the benefits of proposals and involving key decision-makers in the implementation process.

Contributions to sustainable construction projects

The green building consultant plays an essential role from the design phase, integrating sustainability strategies that influence all aspects of the project. Their contribution manifests in several ways:

Masterplan and Sustainable Planning

From the beginning, the consultant helps develop a master plan, often called a "Masterplan", which integrates environmental considerations at all stages of development. This plan ensures that the project meets current regulatory requirements, such as Thailand's local building codes and sustainability guidelines, as well as future standards. The consultant can also guide the process of obtaining environmental certifications such as LEED, EDGE, or the Thai green building certification TREES, ensuring the project's compliance with these certification requirements throughout its development.

Study and Simulation

As part of their mission and based on the established project requirements (local requirements, certification requirements, client requirements), the consultant will implement various models and simulations to evaluate the potential of the recommended strategies and the overall performance of the project. Among these evaluations, the first will be a microclimate analysis, which will determine local conditions such as wind, solar radiation, and rainfall. This information is crucial for defining the optimal building orientation, maximizing its energy efficiency and thermal comfort, and assessing the potential for rainwater harvesting or renewable energy generation, particularly through photovoltaic panels.

Next, the consultant will conduct energy simulations and modeling, considering the choice of materials, the building's thermal mass, and its orientation. These simulations will evaluate the building's energy performance, including heating, ventilation, and air conditioning (HVAC) systems, lighting, and any other relevant energy systems based on the project's scope. The objective is to develop solutions that reduce energy consumption while maintaining an optimal indoor environment.

In addition to these studies, the consultant may also propose a Life Cycle Assessment (LCA) to examine the building's environmental impact throughout its entire life cycle. The LCA helps identify opportunities for sustainable improvement, from material selection to end-of-life.

Education and Training

Finally, the green building consultant acts as an educator, training project teams and clients on best sustainable construction practices and technological innovations. This training is crucial to maintain a high level of ecological awareness and involve all stakeholders in the project's long-term sustainability.
