Sustainability in the Built Environment

Our sustainable building designs focus on comfort, luxury, aesthetics, innovation, efficiency, sustainability, reliability, and longevity. Enhance your rooftop with a garden, farm, or biosolar installation. Create a backyard paradise with a custom-designed pool in a range of stunning styles: lagoon, waterfall, infinity, zero-entry, or beach entry.

Mechanical (HVAC) Design

HVAC systems consume 48% of energy in residential settings and 39% in commercial buildings. Our sustainable designs include various options, such as ducted central air, ductless wall-mounted mini-split, split, direct expansion (DX), and packaged terminal air conditioner (PTAC) systems, to help reduce energy consumption and ensure comfort.

Plumbing Design

Our focus on efficient water supply, distribution, and stormwater and wastewater management contributes to a more sustainable and durable living environment. We offer eco-friendly solutions, including rain gardens, infiltration basins, bioswales, and rainwater harvesting systems, to help conserve water and enhance your surroundings.

Living Roofs

A unique and sustainable roof design featuring a layer of growing medium, a specialized soil, and diverse vegetation, including grasses, herbs, shrubs, and trees. These eco-friendly roofs are commonly known as green roofs, garden roofs, or eco roofs.

Benefits

Grow your own healthy food through urban agriculture, enhance your building's aesthetics with green spaces, help manage stormwater, and reduce noise and air pollution. Triple your roof's lifespan. Increase your solar panel efficiency by 15%. Reduce indoor temperatures by up to 18°F, cooling needs by 25%, and heat loss by 26%.

Layers

From top to bottom, living roofs typically consist of the following layers: vegetation, growing medium, filter, drainage, water + nutrient reservoirs, tough protection mat, root barrier, waterproofing membrane, insulation, structural support.

Options

Low-growing plants like succulents (e.g., sedums), colorful pollinator-attracting flowers, culinary or medicinal herbs, grasses without woody stems, rooftop farm options, and fire-resistant species.

Residential Projects

We use AutoCAD and Revit to design domestic HVAC and plumbing systems for single and multi-family homes, and accessory dwelling units (ADUs).

Commercial Projects

We design HVAC and plumbing systems based on the building application and intended use. Our load calculations and equipment selection process ensure an optimized system.

Sustainability Projects

We design eco-friendly HVAC and plumbing systems that conserve energy and water, utilizing renewable energy and efficient technologies for reduced environmental impact.

Air-Pollution Reduction

Addressing the challenge of anthropogenic air pollution from fossil fuel combustion is crucial. Transportation contributes 28% of total air pollution which is harmful to our health. Our research focuses on the post-treatment of exhaust gases by reducing nitrous oxides (NOx) and oxidizing hydrocarbons (HCs) using catalytic converters with nanoparticle-sized catalysts. Achieving the same catalytic activity with 70-90% less material is made possible by depositing precious metals with a diameter of 5 nm. As the size decreases, the surface area to volume ratio increases, leading to an increased affinity of pollution to bind to catalytic particles through enhanced physisorption and chemisorption. We explore nanofabrication techniques, material selection, nanotetrapods, and metal-organic frameworks (MOFs).
