SUSTAINABLE DESIGN PROCESS MADE TO LAST – Making Things Right

 


Creating enduring architecture goes beyond just aesthetic appeal; it emphasizes the design of spaces that are efficient, durable, and environmentally responsible. The "Design Process Made to Last" is a systematic approach that harmonizes creativity, purpose, and sustainability. This approach ensures that the built environment contributes positively to our legacy.


OBJECTIVE

In my observation, the architectural curriculum during my generation is more focused on aesthetics and architectural styles, which was derived mainly from the historical aspect of design. There was a tandem of principles (Form and Function) that was even the subject of debates instead of integrating them into a common goal. The rest of the curriculum were based on the technical aspect. And so I started with my career applying those principles, until I was assigned to work in industrial facilities dealing with building utilities where I learned about finding sustainable solutions to keep the building occupants comfortable and satisfied. From there I developed a design process that I tend to practice privately, and it lasted for almost throughout my architectural career with lasting results. My objective in this article is to share it with anyone who may find it valuable. Although, I suggest trying it out for a certain period first, to see its effectiveness before deciding to embrace it. This process is somehow very flexible and I don’t remember that it created any conflict with the management policies wherever I worked for. In fact, it was one of the main reasons companies wanted to retain me and offered me certain incentives. They appreciated the responsible approach it brought to my work, which always focused on sustainable solutions in the design process. Below is a step-by-step description of the procedure I want to share with you.


AN EFFECTIVE SUSTAINABLE DESIGN PROCESS:




1. Define Your Project Goals

Every effective design begins with clarity. Start by defining your project's core objectives, which include function, budget, style, and timeline. In today’s world, a durable design also requires an understanding of its environmental impact. Will it reduce energy consumption? Enhance occupant well-being? Promote long-term cost savings? Incorporating sustainability goals at this initial stage sets the groundwork for smarter, greener choices in the future.






2. Consider Design Options

Once goals are established, brainstorm and evaluate different design directions. This stage encourages creativity, but it must be grounded in context. Consider various strategies that align with local climate, building codes, community needs, and environmental performance. For green buildings, this includes exploring options like natural lighting, passive ventilation, rainwater collection, and low-carbon materials. Utilize tools such as life cycle assessments (LCAs) or energy models to forecast the environmental impact of each option.







3. Develop Design Schemes

At this stage, initial ideas are transformed into concrete plans. These refined conceptual designs illustrate space layouts, forms, material selections, and system integrations. Taking a sustainable approach involves using eco-friendly materials, enhancing energy efficiency, and designing for adaptability. It's important to test design schemes for thermal performance, daylight access, and airflow, all while integrating nature and technology to create a resilient design solution.






4. Make Things Right

This phase is where sustainability truly comes to life. “Make things right” is more than just fixing mistakes, it's about aligning your design with ethical, environmental, and future-ready principles.

What it means in a green building context:

  • Right Materials: Choose materials that are locally sourced, non-toxic, recyclable, and low in embodied carbon. Think bamboo, recycled steel, or FSC-certified wood.

  • Right Systems: Design mechanical, electrical, and plumbing systems that reduce resource consumption. Install solar panels, low-flow plumbing fixtures, and energy-efficient HVAC systems.

  • Right Strategies: Incorporate green strategies like biophilic design (connecting people with nature), green roofs, rain gardens, and water reuse systems. Use passive solar design to maximize energy savings.

  • Right Behavior: Encourage sustainability through user-friendly, intuitive design. Clear signage for waste sorting, operable windows for natural ventilation, and visible green features create awareness and foster long-term sustainable habits.


This is the stage where architects collaborate with sustainability consultants, engineers, and even end-users to ensure that the design performs not just today, but over decades. Certifications like LEED, BERDE (Philippines), or WELL can guide the process and act as benchmarks for success.






5. Finalize Your Design Concept

With all aspects aligned - goals, options, and sustainability features, it’s now time to combine the best elements into a final, cohesive design. This design should not only function well on paper but also excel in real-world applications. At this stage, creating detailed drawings and models will help prepare for construction, ensuring that your vision is both practical and environmentally friendly.



FINAL THOUGHTS

Making things right” means designing with intention, where beauty meets responsibility, and function meets the future. Designing long lasting green buildings requires a process that transcends trends. However, even with aesthetics in mind, by embedding sustainability into each step, especially when it's time to "make things right", we create architecture that serves people, protects the planet, and enriches the future.

FREEHAND SKETCHES AND DIGITAL METHOD IN THE DESIGN ARENA (PART 3)

This is the last episode of our 3-part mini-series, the second of which, I concluded with the following words:

As we have been discussing so much about digital design and architecture, I should say that nowadays, AI technology is becoming so popular and widely used in the design industry. It is so phenomenal, and its rapid growth far exceeds all the recorded advancements in the world of digital technology. It is so imminent that even non-professionals can create something that appears professional to many, not only in architecture and interior design, but in almost every field: from song composition and music arrangement to creating artworks, graphic design, and creative writing, among many others. Now, we couldn’t hide the fact that it seems so threatening for designers like us, huh? What do you think? Let’s talk more about it on the last episode of this series. Thanks for following.


As I have always said, “I have nothing against the digital method...” and now we have finally arrived at the most awaited discussion on the role of Artificial Intelligence (AI) in the field of Architecture. In this article, we will explore the term “machine learning,” a subfield of AI, based on a conference presentation written by Mr. Giuseppe Gallo, a PhD candidate in Architecture at the University of Palermo, Italy, and submitted to Academia.edu. In my interpretation, it is through the subfield of machine learning that AI is being applied to the architectural design process.


OBJECTIVE

Although AI is being highlighted in this article, I would still maintain my full support for the importance of manual sketching in the design process. After all, that is actually my main goal, or should I say, an advocacy that I have supported ever since I started discussing this subject matter. Moreover, some parts of this article shall serve as a commentary on the writings of Gallo in order to help us understand more deeply how AI affects the architectural design process. So, some excerpts may be expected occasionally to meet our objective.

According to Gallo, The proliferation of data together with the increase of computing power in the last decade has triggered a new interest in artificial intelligence methods. Machine learning and in particular deep learning techniques, inspired by the topological structure of neurons network in brains, are omnipresent in the IT discourse, and generated new enthusiasms and fears in our society.” And so, this article is somehow aimed at alleviating that growing fear, especially to the professionals who have spent a lifetime of devotion to the field using just their acquired knowledge and manual sketching method.



DEFINING ARTIFICIAL INTELLIGENCE

According to Wikipedia, “Artificial intelligence (AI) refers to the capability of computational systems to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making. It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals. Such machines may be called AIs.”

For me, I still find definitions on Wikipedia sound a little technical in nature, and you still need further reading or more research efforts to get the definition you need, regardless of the specific purpose. I have read the definition of AI in the Academia.edu article I am referring to, but somehow found it a little profound, receiving a combination of opinions from different architects being interviewed at the conference. Most of them are pointing to different subfields of the subject AI, and so, it prompted me to consult with ChatGPT about the different subfields of AI, and here is exactly what I got (exactly what the selected architects interviewed by Gallo are trying to say):

Artificial Intelligence (AI) is a broad and diverse field with many subfields. Each subfield focuses on different aspects of intelligence and problem-solving. Here are some of the major subfields of AI:

1. Machine Learning (ML)

• Definition: A subset of AI that enables systems to learn and improve from experience without being explicitly programmed.

• Types:

○ Supervised Learning: Learning from labeled data to make predictions.

○ Unsupervised Learning: Learning from unlabeled data to identify patterns or structures.

○ Reinforcement Learning: Learning through trial and error, receiving rewards or penalties based on actions taken.

○ Semi-supervised Learning: Combines labeled and unlabeled data for learning.

○ Deep Learning: A type of machine learning based on neural networks, especially deep neural networks.

2. Natural Language Processing (NLP)

8. Artificial General Intelligence (AGI)

• Definition: A hypothetical AI system that can perform any intellectual task that a human can do.

• Research Goal: Achieving human-like cognitive abilities in machines.

• Current Status: Still theoretical and not yet realized.

9. Fuzzy Logic

• Definition: Deals with reasoning that is approximate rather than fixed and exact, mimicking human reasoning.

• Applications: Control systems, decision-making, and systems where precision is not required.

10. Swarm Intelligence

• Definition: Inspired by the collective behavior of decentralized, self-organized systems (e.g., bird flocks, insect colonies).

• Applications: Optimization problems, robotic control, and network design.

11. AI Ethics

• Definition: The study of ethical issues related to AI development and usage.

• Issues: Bias in AI models, data privacy, accountability, AI fairness, and ensuring AI systems are aligned with human values.

12. Neural Networks

14. Human-Computer Interaction (HCI)

• Definition: The design and use of computer technology that interacts with human users.

• Applications: User interfaces, voice assistants, and smart devices.

These subfields often overlap, and researchers may work in multiple areas simultaneously. Together, they contribute to making AI systems more capable, adaptive, and intelligent.

I think I am now finding myself getting too far from my real objective. But somehow, this time I just have to use my intuition to simplify the definition. Let’s just begin with a machine that can think like a human. Perhaps now, you are thinking about a robot. But this robot, although it can talk, perhaps write, or communicate with us in any way it can, still, the information it could provide will depend on the data received from humans, initially from its creator or inventor, then from the users themselves. The learning process could be both supervised and non-supervised, allowing the AI to process available data by itself or while being trained by the inventor or the users. In the long run, both the AI and the users tend to benefit from each other and develop a reciprocal and infinite learning process. Now, in the light of architecture, I would rather attribute the traditional sketching to human ability and the parametric architecture to AI ability. For me, both are useful tools in the design process and cannot be separated from each other. Well, by integrating some of the technical definitions initially derived from research, I hope I am able to satisfy the objective that we are trying to reach here.


WILL AI BE USEFUL IN ARCHITECTURE?

This was an important question Mr. Gallo asked when he interviewed ten architects of different specialties from February to July 2019. It somehow turned into a survey where the participants tend to vote on certain categories. So, to cut the story short, here’s a table and an excerpt of the result:


Machine Learning is the technology that obtained the highest score with a total of 53 out of 70 achievable points, followed by digital manufacturing with 51, third “other computational methods” with 47, then Internet of things with 38, BIM and Augmented Reality with 37, last Virtual Reality with 30. It is interesting to note that Machine Learning and "other computational methods" both obtained the first place in the personal rankings of the designers four times, as well as happened twice for BIM and once for Digital Manufacturing. It is therefore clear that based on the experiences and expectations of the interviewed designers, machine learning and its derivations are expected to play a role within the architectural practice, a role that, for many of the interviewees, will be decisive in ten years.”

Such a piece of concrete information somehow supports my own definition of AI, as I have provided above, and has somehow satisfied the objective of this article. However, if you still need further clarification, let's discuss further, and please feel free to leave a comment.


EXPECTATIONS OF AI TECHNOLOGY IN ARCHITECTURE

It has been five years since Gallo conducted his research work, and the above survey was projected for ten years. Here’s an excerpt:

Architecture is a complex practice. On the contrary, sectors where Artificial Intelligences are showing an important impact, have a more linear nature than that of our profession. The interviewee goes on saying that, by breaking up the architect's work into separate tasks, describing the process rigorously, it is easier to imagine an AI capable of solving these operations individually. It is therefore important to ask ourselves several questions: Are we able to manage these enormous potentials to generate new concepts and ideas? Can we describe this complexity so that a machine can process it? Maybe in the future.”

Now that we are actually more than halfway through the projected time of the survey, do you think that at that time, they might have overlooked the capability of AI technology in the field of Architecture? The way I experienced it, it came so drastically at a very high speed, that even non-professionals could produce professionally looking products on their own. I guess that’s where it becomes intimidating for the professional community.

AI may sound intimidating due to the unpredictable speed in terms of the development of technology. However, as we continue reading Gallo’s research, he says:

It is therefore still too early to understand how much these technologies will erode from an architect's professional practice, and certainly nothing in terms of responsibility. In this sense, Arthur Mamou-Mani declares that even by using AI, designers retain the right to control the design process at any time, making choices and questioning answers provided by artificial intelligence.”

This was exactly what I was trying to point out as I concluded in my first episode:

In the next episodes, we can expect AI to enter the arena. Oh well, let's just welcome it, but I believe we should not let it dominate the show. Instead, let us use our own creativity and use AI as a modern tool only that we have full control of. Use it to enhance our own ingenuity, nothing more, nothing less.”

Now, it seems like the majority of the comments I heard from other famous architects add up to my confidence that I am on the right track when I say I support the advocacy of retaining the manual sketching method in the design process. For me, this is some sort of sustainability that matters in the field of architecture.


FINAL THOUGHTS

In the first episode of this mini-series, I mentioned in my conclusion that "it is the cultural identity and the sense of originality of the architect or artist that I want to emphasize and preserve in this endeavor. The bottom line is that we should stop arguing about which one is best. Let's discuss this with a sense of balance." That was when I discussed the integration of computer technology in the manual sketching method used in the design process. Well, I would say it would be the same thing in the use of AI technology. Instead of being intimidated, let us be confident that AI is a helpful tool in our professional practice. If we could train it, then we could definitely control it. Let’s be friends with them, a new colleague whom we can trust and rely on based on accuracy and consistency. But what about loyalty? Oh well, don’t you dare compare them to a colleague next to your cubicle. Just kidding aside...

Thanks for joining me throughout this mini-series. Hoping we could have more of this...what do you think?
