Engineering Design for Green Roofs,
Mechanical, HVAC & Plumbing

living room

We offer innovative designs in the following disciplines: green roofs, mechanical, and plumbing and are passionate about solving challenges in sustainable building design. Our design criteria ensure comfort, luxury, aesthetics, innovation, efficiency, sustainability, reliability, and longevity.


Our HVAC designs prioritize comfort and energy efficiency. HVAC systems account for 48% of building energy consumption in residential settings and 39% in commercial. We offer designs for ducted central air, ductless wall-mounted mini-split, split, direct expansion (DX), or packaged terminal air conditioner (PTAC).

indoor pool

Experience the harmonious blend of serenity and sustainability with a garden roof, rootop farm, or bioswale, complemented by energy conservation with rooftop solar or biosolar. Transform your home into a tranquil oasis with a lagoon pool, majestic waterfall, or a see-through waterslide.

Green Roofs

A unique roof design featuring soil and vegetation, commonly known as a garden, living, or eco roof.


Grow your own healthy food through urban agriculture, add to your building's beauty with green spaces, 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%.

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


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.


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).
