PRESERVING CULTURAL HERITAGE THROUGH SUSTAINABLE ARCHITECTURE (PART 3)

ELMIS Gabaldon Building, a Filipino style heritage structure was situated in Brgy Paraiso, Sagay City Negros Occidental, Philippines, previuosly part of Brgy Fabrica during spanish colonization. This building was used as hideout of our Filipino Armed Forces in combating Japanese during World War 2. The building was burned and destroyed during the war. Currently, the structure has been restored and used as Grade School Building.

Heritage Buildings Restoration: A Challenging but Sustainable Path for Filipino Architecture

The Philippines is full of stories and culture that come alive through its historic buildings - think about pre-colonial vernacular houses, colonial homes, ancestral homes, and public buildings. These places aren't just old landmarks; they’re a reflection of Filipino identity, skills, and shared memories. But with city growth speeding up and climate change becoming a bigger concern, fixing up and protecting these buildings isn’t just urgent; it’s also an incredible chance to celebrate our heritage.


OBJECTIVE

In this post, we’ll look at how restoring these old buildings, even though it can be tricky, plays a big role in building a sustainable future for Filipino architecture. This is the 3rd and last part in a series of the same title. To get the full picture, you may want to read the previous episodes first before proceeding. Below are the links:


Challenges in Heritage Restoration in the Philippines


Funding and Maintenance Issues

Restoring old buildings isn’t cheap—it needs skilled workers, traditional materials, and usually takes quite a bit of time. Many historical sites, especially those way out in rural areas, tend to fall apart because there’s not enough funding to keep them up which eventually becomes one of the biggest challenges in heritage conservation. Without some kind of financial support or incentives, it’s tough to take care of these places, so they end up getting worse over time.


Balancing Modern Use with Preservation

Restoring old buildings for modern use, whether it’s for homes, shops, or public spaces, takes a careful touch. How do we add things like air conditioning or plumbing into a 200-year-old structure without spoiling its historic charm? Sometimes, bad renovations can ruin important architectural details, while being too strict about preservation can make buildings feel outdated or unusable. Finding that perfect balance between keeping the original feel and making the space functional, that’s the tricky part, both ethically and creatively.


Lack of Awareness or Undervaluing of Heritage

There are still people who are not really aware, or should I say not interested on how to appreciate the value of heritage buildings, especially younger folks or in developed places that are rapidly modernizing. Many see old structures as outdated, not making enough money, or just not worth keeping. Because of this, they often end up getting torn down or left to decay, especially when the land could be much more profitable for shopping malls, condos, or new infrastructure projects.


Natural Disasters and Climate Change Impacts

Since it's located right in the Pacific Ring of Fire and often struck by typhoons, the Philippines is pretty vulnerable to natural disasters. Earthquakes, flooding, and storms can cause serious damage, especially to older buildings that weren’t really designed to handle today’s environmental challenges. Plus, with climate change ramping up these problems, protecting these structures over the long run just gets more complicated and expensive.

Moving Forward: Recommendations and Call to Action


Support Government Policies That Integrate Cultural Heritage into Building Practice

We really need to support laws that see heritage buildings as part of a bigger picture of sustainability. Offering perks like incentives for reusing old structures, tax breaks for preservation work, and guidelines that blend keeping history with eco-friendly features, like installing solar panels or designing for passive cooling, can help make sure these buildings stay around and remain environmentally friendly.


Encourage Youth Education on Filipino Architecture

Bringing heritage education into the school program, whether through field trips, community projects, or design contests. These can really get kids interested and proud of Filipino architecture early on. When young folks learn why these heritage buildings matter, they’re more likely to grow up wanting to protect, appreciate, and maybe even work in this field one day.


Promote Community-Led Restorations

Communities that actually use and care for heritage sites tend to take better care of them. When you teach local artisans traditional building skills, involve the community in making decisions, and give barangays the power to handle restoration projects, it really creates a sense of pride and ownership. Plus, it helps make sure that the work stays true to local traditions and tells the story of the place.


Foster Tourism That Respects Heritage

Heritage tourism can be a great way to fund restoration projects and help people connect with different cultures. With that being said, it’s important to keep things monitored so that things don’t get overrun with commercial stuff or end up damaging delicate historic sites. By focusing on sustainable tourism, things like education, preservation, and giving back to local communities, these historic buildings can become bright museums that fit right into today’s world without losing their charm.


FINAL THOUGHTS

Reviving our heritage buildings isn’t just about looking back; it’s a smart move for our future. These old structures, built with traditional materials and techniques that are often better suited to our climate, hold ecological and cultural value. By fixing them up, we cut down on the environmental impact of building new stuff and stay connected to our roots. Our heritage architecture shows who we are as Filipinos - our resilience, creativity, and stories. Taking care of these buildings means future generations will not only have useful spaces but also meaningful places that tell our story.

Preserving the past is building a more sustainable future.”

SUSTAINABLE CONSTRUCTION PRACTICES: Building Responsibly from the Ground Up


In the rapidly changing field of architecture, sustainability has evolved from a mere buzzword into a significant responsibility. Sustainable construction practices are the cornerstone of green architecture, seeking not only to minimize environmental impact but also to foster social and economic equity throughout the building process. In this blog, we delve into the essential sustainable construction practices, thoughtfully categorized into three pivotal stages: Pre-construction, Construction, and Workforce Facilities. Together, these stages illuminate the path toward a more sustainable future in the field of architecture.


OBJECTIVE

I am not quite convinced that when it comes to the term “construction,” it’s time for the non-techies to leave the conference room. I believe that, the more they should be involved simply for awareness purposes when it comes to construction site safety, wearing PPEs, learning the signs and danger zones, not to mention the environmental impact. As usual, I am sharing information based on my education and work experiences. I remember decades ago, I was assigned as the site safety officer while working on a project somewhere in Southeast Asia. I just thought that somehow, it would help me encourage techies and non-techies to be mindful not only in terms of sustainability and safety, or dust and noise, but also waste management, all of which are very crucial in the construction field. If we work hand-in-hand, we will be able to reach the zero-accident and zero-waste goal and create a safe and healthy, sustainable environment on-site.



1. Pre-construction: Laying a Responsible Foundation

Sustainability begins before the first brick is laid. Proper planning and thoughtful site preparation are crucial to minimizing ecological disruption.




- Preparation of Construction Management Plan

A Construction Management Plan (CMP) is the blueprint for executing sustainable practices on site. It outlines methods to minimize environmental impact, optimize resource use, and ensure workers’ welfare.

A well-developed CMP addresses aspects such as:

By formalizing sustainability goals within the CMP, construction teams can ensure consistent and measurable implementation of its principles and policies throughout the project.





- Site Barricading

Securing the construction site first and foremost with appropriate barricades helps control access and protect the surrounding environment. Barricades prevent unintentional damage to adjacent natural features and reduce dust dispersion. For instance, fencing around preserved trees and water bodies ensures that they remain untouched during the entire construction phase.





- Topsoil Preservation

Topsoil is very rich in organic matter and nutrients essential for vegetation. Rather than discarding it, sustainable construction mandates careful removal, storage, and reuse for landscaping or garden areas post-construction. However, they can even be used temporarily during the construction period for the workers and families to produce on-site for their own consumption. This practice not only saves resources but also helps restore ecological balance.






- Protecting Existing Site Features and Trees

Wherever possible, existing site features such as old trees, natural rock formations, or streams should be preserved. Redesigning layouts to accommodate nature or creating protective zones around trees to prevent root damage is a good professional practice. Preserving these elements maintains biodiversity and adds aesthetic and environmental value to the final structure.



2. During Construction: Minimizing Impact in Real Time

The construction phase has the highest potential for environmental disruption. However, with the right strategies, its impact can be significantly mitigated.





- Dust Suppression Measures

Construction activities generate airborne dust, which can harm respiratory health and damage nearby vegetation. Regularly sprinkling water on access roads, installing dust nets, and limiting the movement of uncovered materials are effective ways to control dust levels.




- Noise Control

Prolonged construction noise affects nearby communities and wildlife. Using low-noise machinery, scheduling noisy operations during daytime hours, and installing acoustic barriers can drastically reduce this impact. Secure proper PPE for the noise protection of workers.



- Material Movement and Management

Efficient handling of construction materials may reduce emissions, wastage, and unnecessary costs. Using local and prefabricated materials minimizes transportation, thus regulating carbon footprints. Organizing centralized storage areas ensures materials are handled fewer times and less space is disturbed.


- Stormwater Management

Rainfall runoff from construction sites can carry pollutants into local waterways. Temporary measures like sediment traps, retention ponds, and permeable surfaces help manage stormwater and prevent erosion and water pollution.






- Construction Waste Management

Instead of sending waste to landfills, sustainable construction promotes on-site segregation and recycling. Separate bins for wood, metal, concrete, and plastics, along with partnerships with recycling facilities, ensure responsible disposal and reuse.


- Disaster Risk Mitigation

Sites should be prepared for natural or accidental disasters. Elevated storage, secured scaffolding, and clearly outlined evacuation and response plans safeguard both workers and materials from unpredictable events like floods, earthquakes, or fires.



3. Facilities for Construction Workforce: Supporting the Human Element




True sustainability extends beyond the environment to the people involved. Ensuring the health, safety, and dignity of the construction workforce is an ethical obligation.

- Healthy Conditions for the Construction Workforce

Workers deserve a clean, hygienic, and well-ventilated environment. Providing drinking water stations, shade for breaks, and regular health check-ups ensures their well-being during demanding workdays.


- Safety Measures During Construction

Strict adherence to safety protocols can save lives. Personal Protective Equipment (PPE), safety training, visible signage, and regular inspections reduce accident risks significantly.


- Provision of Basic Amenities

Basic facilities such as clean toilets, rest areas, and handwashing stations are essential for maintaining hygiene and morale on-site. These amenities reflect respect and dignity for the workforce.


- Health and Education for Workers’ Children

Social sustainability includes caring for workers' families. On-site children’s daycare centers, tie-ups with local schools, and community health centers for children’s needs, to ensure that the workforce can focus on their jobs without compromising their families’ needs.



FINAL THOUGHTS: Building for the Future

Sustainable construction practices transcend mere carbon footprint reduction; they are about nurturing vibrant communities, safeguarding precious ecosystems, and championing equity. By weaving these principles into every phase of construction, we pave the way for a future where architecture beautifully coexists with both people and the planet. For architects, builders, and passionate advocates of sustainable development, remember that every mindful choice made on-site is a step toward leaving a lasting legacy of responsible and inspiring construction. Together, we can create a world where our buildings reflect our commitment to a greener, more equitable future.
