OMD has produced sustainable building designs, also known as "Green building" (or "green architecture"), it has delivered projects that embody environmentally-conscious architecture design technique. Projects that seek to minimize the negative environmental impact of buildings by enhancing efficiency and moderation in the use of materials, energy, and development of space.

• While planning and design early decisions have the greatest impact on energy efficiency, passive solar design, day lighting, and natural cooling
• Sustainable design is more of a philosophy of building than a prescriptive building style.
• Sustainable buildings don't have to cost more, nor are they more complicated than traditional construction
• Integrated design, that is design where each component is considered part of a greater whole, is critical to successful sustainable design
• The elements of building design can be: energy saving architectural features, energy conserving building envelope.

We study the linked domains of sustainability, environmental (natural patterns and flows), economic (financial patterns and equity), and social (human, cultural, and spiritual). Sustainable designs are produced by a collaborative process that involves holistic and creative approach that connects land use and design at the regional level and addresses community design and mobility; site ecology and water use; place-based energy generation, performance, and security; materials and construction; light and air; bioclimatic design; and issues of long life . True sustainable designs are beautiful, humane, socially appropriate, and restorative of natural systems. We consider following guide lines:

• Reducing energy in use
• Minimizing external pollution and environmental damage
• Minimizing internal pollution and damage to health
• Reducing embodied energy and resource depletion & Reduce human exposure to noxious materials
• Conserve non-renewable energy and scarce materials
• Minimize life-cycle ecological impact of energy and materials used & Use renewable energy and materials that are sustainably harvested
• Protect and restore local air, water, soils, flora and fauna
