Sustainability in the Built Environment

Our sustainable building approach harmoniously blends comfort, luxury, aesthetics, innovation, efficiency, sustainability, reliability, and longevity. To elevate your rooftop experience, consider incorporating a garden, farm, or biosolar installation. Create a backyard paradise with a custom pool featuring lagoon, waterfall, infinity, zero-entry, or beach entry styles.


Mechanical HVAC Design

Mechanical HVAC systems consume 48% of energy in residential settings and 39% in commercial buildings. We assist you in selecting the ideal system to reduce energy consumption while maintaining optimal comfort. Some HVAC options include ducted central air, ductless wall-mounted mini-split, split, direct expansion (DX), and packaged terminal air conditioner (PTAC) systems.

Plumbing Design

Our plumbing design focuses on efficient water supply, distribution, and stormwater and wastewater management. By incorporating eco-friendly solutions such as rain gardens, infiltration basins, bioswales, and rainwater harvesting systems, you can conserve water, mitigate runoff, reduce pollution, and create visually stunning surroundings.

Living Roofs

Living roofs, also known as green roofs, garden roofs, or eco roofs, comprise a layer of growing medium and specialized soil that supports various vegetation, including grasses, herbs, shrubs, and trees. By choosing this innovative and eco-friendly alternative for your roof, you can set your building apart while creating a sustainable, visually captivating environment that offers numerous benefits.


Living roofs fosters urban agriculture, providing fresh produce while enhancing aesthetics. These eco-friendly spaces manage stormwater, mitigate noise and air pollution, and triple roof lifespan. Living roofs enhance solar panel efficiency by up to 15%, decrease indoor temperatures by 18°F, and lower cooling needs and heat loss by 25% and 26%, respectively.

Living roofs comprise multiple layers, each playing a vital role in their functionality. From top to bottom, these layers include: vegetation, growing medium, filter, drainage, water and nutrient reservoirs, tough protection mat, root barrier, waterproofing membrane, insulation, and structural support.


Crafting a sustainable, visually captivating, and biodiverse living roof environment requires the careful selection of appropriate plants. Some options are low-maintenance succulents like sedums, colorful pollinator-friendly flowers, culinary and medicinal herbs, edible plants, non-woody stem grasses, and fire-resistant species.

Air-Pollution Reduction

With the aim of reducing air-pollution, our research is dedicated to mitigating harmful vehicle exhaust emissions. We prioritize post-treatment of exhaust gases using nanoparticle-sized catalysts in catalytic converters, which achieve comparable catalytic activity with 70-90% less material. To further optimize catalyst design, we are investigating various nanofabrication techniques and exploring different material selections. Addressing transportation-related pollution is crucial, as it contributes to 28% of total air pollution.
