URBAN BEEKEEPING AND GREEN BUILDINGS: Supporting Biodiversity in Tropical Cities

As Philippine cities evolve and urban density increases, the concept of green building is transforming beyond just energy efficiency and water conservation. Today, sustainable buildings are designed not only to reduce their ecological footprint but also to foster urban ecosystems, enhance biodiversity, and promote community well-being. A compelling and effective practice that aligns with these aspirations is urban beekeeping. Once confined to rural landscapes, beekeeping is now thriving on rooftops, green roofs, and in mixed-use developments in vibrant cities around the world, and this could be possible if not done so in any Philippine crowded cities like Metro Manila, Cebu, and Davao. When thoughtfully implemented, urban beekeeping not only enriches the ecological value of green buildings but also supports sustainability efforts in urban tropical environments. Embracing this practice can lead to healthier cities, stronger communities, and a thriving environment for both people and pollinators.

OBJECTIVE

These are a mix of academic research, expert commentary, and reputable reporting that relate directly to urban beekeeping, biodiversity, green roofs, and sustainable buildings. This blog serves as an essential supplement to my previous discussions on green building, seamlessly weaving together conceptual insights, practical applications of sustainability, and captivating case studies on biodiversity and ecosystems that highlight their relevance to tropical climates. Moreover, it aligns perfectly with green building rating systems, culminating in a powerful conclusion while offering valuable citations for readers eager to delve deeper into this critical topic.

Urban Beekeeping in a Tropical Context

In tropical countries such as the Philippines, biodiversity is naturally high, but rapid urbanization has fragmented habitats for pollinators. Concrete surfaces, heat islands, and the loss of flowering vegetation threaten bees and other insects essential to food systems. Urban beekeeping reintroduces pollinators into city environments, especially when paired with Green roofs and sky gardens, vertical greenery systems, and urban farms and community gardens. In the Philippine context, bees can thrive year-round due to the warm climate and availability of flowering plants, making cities surprisingly suitable environments when properly designed. In this case I would greatly advise clients or building owners to carefully plan on any projects involving beekeeping. Seek professional advise such as sustainability specialized architects, biologists, environmental scientists, etc.

Strengthening Biodiversity Through Green Buildings﾿

A key goal of green building is to restore ecological function, not just reduce environmental harm. Rooftop beehives support pollination of native and ornamental plants. Bees help maintain healthy vegetation in green roofs and landscaped podiums. Pollination improves plant resilience, contributing to urban cooling and stormwater management. Scientific research shows that green roofs can support diverse communities of bee species in urban areas, acting as habitat patches and sources of forage in otherwise hardened landscapes.

Beekeeping activities (e.g., rooftop apiaries) and enhanced pollinator habitats support broader ecological strategies that help buildings perform better across sustainability metrics.

Responsible Design and Local Considerations

To ensure urban beekeeping supports green building goals, careful planning is essential:

• Proper hive placement away from pedestrian areas

• Use of locally appropriate or native bee species

• Compliance with local ordinances and barangay regulations

• Professional hive management to ensure safety and bee health

Urban beekeeping must be designed to minimize conflicts, ensure safe coexistence, and protect pollinator welfare in densely populated areas.

FINAL THOUGHTS: Buildings as Living Participants

Urban beekeeping revolutionizes green buildings, turning them from mere structures into vital participants in urban ecosystems. In tropical cities like those in the Philippines, where biodiversity and climate challenges converge, this practice not only supports pollinators but also enhances green roofs, fosters community connections, and strengthens ecological resilience. By embracing urban beekeeping, green buildings can truly fulfill their mission: harmonizing with nature, even in the bustling heart of the city.

It also aligns with green building rating systems, culminating in a strong conclusion and providing valuable citations for deeper exploration.

Minimalist architecture embodies the principle of "less is more," prioritizing function over unnecessary embellishments. By focusing on simplicity in form and space, genuine expression of materials, and the removal of superfluous elements, minimalist design evolves into a powerful tool for achieving sustainability goals. When thoughtfully applied, minimalism transcends mere aesthetics to become a strategic approach that benefits both the environment and the user.

The following are the major roles that Minimalist Style play in Sustainable Architecture

1. Reduced Material Use and Construction Waste

Minimalist buildings intentionally limit the number of materials used, focusing only on what is essential. Sustainable benefits include lower material consumption, reduced construction waste and decreased embodied energy. By avoiding excessive finishes and decorative layers, minimalist architecture reduces resource extraction and manufacturing impacts—key concerns in sustainable construction.

2. Smaller, Efficient, and Purposeful Spaces

Minimalist design favors compact and well-organized layouts rather than oversized or underutilized spaces. This results in lower energy demand for heating, cooling, and lighting; reduced land use and site disturbance; and encouragement of multifunctional spaces. Space efficiency directly supports sustainability by reducing both operational and environmental costs over a building’s life cycle.

3. Maximizing Natural Light and Ventilation

Minimalist architecture often incorporates:

• Open floor plans

• Large, strategically placed windows

• Simple building forms that enhance airflow

Environmental advantages:

• Reduced reliance on artificial lighting

• Improved natural ventilation

• Enhanced indoor environmental quality (IEQ)

In tropical regions such as the Philippines, these strategies help reduce cooling loads while maintaining occupant comfort.

4. Honest and Durable Use of Materials

Minimalist architecture frequently highlights materials in their natural or raw state, such as exposed concrete; natural timber; stone and steel. These materials are often chosen for their durability and longevity, reducing the need for frequent replacement or maintenance. Using fewer surface finishes also minimizes the use of chemicals, adhesives, and coatings that can negatively impact indoor air quality.

5. Simplified Construction and Lower Carbon Footprint

Minimalist buildings typically use: simple geometries; repetitive structural modules; and straightforward construction systems. This simplicity leads to: faster construction timelines; reduced labor and material waste; and lower overall carbon emissions. Efficiency in construction directly supports sustainable building objectives.

6. Compatibility with Passive Design Strategies

Minimalism works seamlessly with passive design principles, which are central to sustainable architecture.

These include:

EARTH-SHELTERED HOMES: A Natural Strategy for Sustainable and Green Architecture

As climate change and urban expansion pose increasing challenges to building design and construction, architects and planners are rediscovering nature as a source of innovative solutions. One of the most effective strategies is the earth-sheltered home — a structure that is either partially or entirely covered by soil. This groundbreaking architectural approach leverages the earth itself for insulation, protection, and as an environmental buffer, making it an exemplary model for sustainable architecture and green building practices.

OBJECTIVE

In this blog, we will delve into the essential impact of earth-sheltered homes in advancing green building concepts. These innovative homes not only align with but also enhance the three pillars of green building: environmental, economic, and social sustainability. As a key solution for architects dedicated to crafting eco-friendly dwellings, earth-sheltered homes are pivotal in our journey toward a sustainable future. I urge everyone—regardless of your background—to get involved in this critical dialogue, as each of us has a vital part to play in promoting a healthier, greener world for generations to come.

What Is an Earth-Sheltered Home?

An earth-sheltered home is a structure that is built into the ground or covered by soil on one or more sides. There are three main types:

• Bermed homes – Earth is packed against the exterior walls on one or more sides.

• Hillside (in-hill) homes – Built directly into a slope, with one exposed façade.

• Underground homes – Entirely below ground, often with central courtyards or skylights.

These homes are designed to take advantage of the earth’s naturally stable temperatures to improve comfort and reduce energy demands.

Contribution to Sustainable Architecture

1. Energy Efficiency Through Passive Design

The soil surrounding earth-sheltered homes acts as a natural thermal mass: keeps indoor temperatures stable throughout the year; reduces heat loss in cold seasons; and minimizes heat gain in hot climates. This reduces reliance on mechanical heating and cooling systems, which lowers energy consumption and carbon emissions — a key goal of green buildings.

2. Reduced Carbon Footprint

Earth-sheltered homes contribute to climate change mitigation by lowering operational energy use, reducing dependency on fossil-fuel-powered systems and extending building lifespan due to protection from weather. Over time, this significantly decreases the building’s overall lifecycle carbon footprint.

3. Preservation of Natural Landscape

Unlike conventional housing, earth-sheltered homes blend into their surroundings: roofs can be vegetated to create green roofs; natural landforms remain visually intact and wildlife habitats and vegetation can be restored over the structure. This low-impact development approach aligns with sustainable land-use planning principles.

4. Climate Resilience and Disaster Protection

The surrounding earth provides strong physical protection: high resistance to strong winds and storms; natural fire resistance compared to exposed wooden structures; and protection from temperature extremes. This makes earth-sheltered homes valuable in regions facing increasingly severe climate events.

5. Improved Indoor Environmental Quality

Earth-sheltered homes naturally support healthier indoor conditions by providing superior sound insulation, more stable indoor humidity, and protection from outdoor dust and air pollution. When combined with proper ventilation and daylighting systems, they create comfortable, healthy living environments.

6. Water Conservation and Management

These homes often integrate sustainable water strategies such as rainwater harvesting systems, green roofs that slow stormwater runoff, and natural soil filtration around the structure. This reduces pressure on municipal drainage systems and supports water conservation goals.

Role in Green Building Concepts

Earth-sheltered homes strongly support the three pillars of green building:

Green Building Pillar	Contribution of Earth-Sheltered Homes
Environmental	Reduces emissions, preserves landscapes, improves biodiversity
Economic	Lowers long-term energy and maintenance costs
Social	Creates healthier, quieter, more comfortable living spaces

They also align with international green building standards such as those promoted by the U.S. Green Building Council through energy- and site-efficiency-focused rating systems.

Real-World Examples

Notable earth-sheltered projects include:

• Earth House Estate (Dietikon, Switzerland)

• Malator House (Pembrokeshire, Wales)

• Hockerton Housing Project (United Kingdom)

These projects demonstrate how earth-sheltered design can be successfully implemented in modern housing.

Challenges and Considerations in General

Despite their many benefits, earth-sheltered homes require careful planning:

• Effective waterproofing and drainage systems

• Proper ventilation and moisture control

• Higher initial construction costs in some cases

However, these challenges are usually offset by long-term environmental and energy savings.

Challenges in the Philippines

Earth-sheltered homes make sense in the Philippines due to its hot, humid and typhoon-prone climate which makes passive cooling and structural resilience essential. However, despite of its promising potentials, there exist some several local challenges that must be considered:

• High groundwater levels in coastal and lowland areas;

• Soil stability and landslide risks in mountainous regions;

• Need for skilled waterproofing and structural engineering; and

• Higher initial construction expertise requirements.

These challenges requires proper site selection, specialized technical design and adherence to government's green building/environmental laws and certifications.

FINAL THOUGHTS

Earth-sheltered homes serve as a transformative approach in sustainable architecture, harnessing natural systems to enhance living environments. By utilizing passive thermal control, minimizing environmental impact, and bolstering resilience, they exemplify the key tenets of green building. As the construction industry increasingly embraces lower-carbon and climate-responsive designs, earth-sheltered homes emerge as both a practical and visionary solution for a sustainable future.

Yet, as we face the urgent challenge of climate change, a transformative movement is taking root in architecture. Sustainable design is not only gaining importance but is evolving into a powerful new trend. Enter Eco-Brutalism—a fusion of traditional Brutalism with eco-friendly principles. This innovative approach represents a crucial step toward addressing our environmental concerns while honoring architectural history. Join me as we delve into the compelling world of Eco-Brutalism in this blog article.

What Is Eco-Brutalism?

Eco-brutalism is a contemporary design approach that integrates Brutalist architectural aesthetics with environmentally responsible design principles. It retains the visual strength and geometric clarity of Brutalism while embedding biological and ecological systems such as:

• Green roofs and rooftop gardens

• Vertical forests and green walls

• Passive ventilation and daylighting strategies

• Renewable and low-carbon building materials

• Climate-adaptive landscaping

Instead of softening the structure with ornamental details, eco-brutalism emphasizes coexistence between concrete and nature—inviting plants to climb, spill, and envelop the built form.

Characteristics of Eco-Brutalist Architecture

1. Integration of Greenery

Eco-brutalist buildings commonly feature:

• Cascading plants on concrete balconies

• Moss-covered retaining walls

• Terraced gardens embedded into the façade

• Vegetated podiums and walkways

Greenery softens the heavy concrete massing while improving microclimates and biodiversity.

Without these, a building may appear sustainable without delivering long-term environmental performance—what some call “greenwashing”.

Why Eco-Brutalism Is Gaining Popularity

Several factors contribute to the rise of eco-brutalism:

• Climate-responsive design is more important than ever.

• Urban areas need more green spaces without expanding outward.

• Younger generations are drawn to authentic, raw aesthetics paired with sustainability.

• Cities seek architecture that is both resilient and restorative.

Eco-brutalism offers a middle ground—maintaining structural integrity while reintroducing life and nature into the built environment.

Notable Examples of Eco-Brutalism 

Oasia Hotel Downtown — Singapore (See cover Photo)

• Oasia Hotel Downtown is a 27-storey mixed-use tower whose façade is covered with climbing plants belonging to dozens of species — over time the concrete + mesh exterior becomes cloaked in greenery.

• About 40% of the building’s volume is devoted to communal sky gardens and open-air terraces.

• The design uses natural ventilation and open garden terraces instead of purely air-conditioned enclosed spaces — promoting biodiversity (insects, birds) and creating a “vertical ecosystem.”

• This shows eco-brutalism at large-scale: a concrete high-rise reimagined as a living structure, reducing the environmental footprint while offering urban green space.

The Barbican Centre, Facade

The Barbican Centre — London, UK

• While originally built as a classic brutalist structure, the Barbican Centre has undergone sustainable retrofits, integrating green practices and plant-filled spaces.

• Its conservatory holds more than 1,500 plant species, turning part of the concrete estate into a lush, biodiverse environment.

• This example shows another face of eco-brutalism — not only in new buildings but also in how older, concrete-heavy structures can be reimagined and rehabilitated to support green design and urban ecology.

The future of wind energy is not just bright; it's transformative. According to projections by the IEA and IRENA, by 2050, wind power could meet 35–40% of the world's electricity needs, significantly reducing carbon emissions by billions of tons each year. Moreover, this renewable energy source can be leveraged to produce green hydrogen, paving the way for decarbonizing heavy industries and transport sectors.

As governments, businesses, and communities rally around climate action, wind energy is positioned to become a fundamental pillar of global sustainability. It will not only drive innovation and create countless jobs but also empower nations in their journey toward a net-zero future. Embracing wind energy means investing in a cleaner, healthier planet for generations to come.
