LEED (BD+C)
Building Design and Construction
The framework for constructing a holistic green building is provided by LEED for constructing
Design and Construction (LEED BD+C). This framework allows you to identify every sustainability feature and optimize the benefits. LEED BD+C offers a variety of options to accommodate any endeavor.
Major Renovation and
New Construction.
The framework for constructing a holistic green
building is provided by LEED for constructing Design

LEED (O+M)
Building Operations & Maintenance
The LEED O+M rating system offers a proven roadmap for enhancing the sustainability of existing
buildings throughout their lifecycle. By focusing on resource efficiency, occupant health, and
continuous improvement, it helps you cut operating costs, reduce environmental impact, and
foster a healthier indoor environment.
Performance Benchmarking for
Existing Operations
Establish baseline metrics for energy,
water, waste, and indoor environmental
quality to pinpoint efficiency gaps and set
measurable improvement targets.
Ongoing Systems Optimization
Implement operational best practices
such as preventive maintenance,
automated controls, and occupant
engagement—to drive continual gains in
building performance and comfort.
LEED (ID+C)
Interior Design & Construction
The LEED ID+C rating system guides sustainable interior projects—from conceptual fit-outs
through final handover—by embedding green design principles, healthy materials, and efficient
construction practices into every aspect of your build-out.
Design & Material Strategy
From the very beginning, your interior project
is guided by space-planning principles that
maximize natural daylight, optimize occupant
comfort, and reduce energy use. Material
selections emphasize low-emitting products,
and recycled content
Indoor Environmental Quality
Optimization
During construction, a comprehensive
waste-diversion program ensures that
surplus materials are sorted, reused
where possible, and recycled—keeping
landfill contributions to a minimum. Once
the space is occupied.
MOSTADAM (D+C)
Building Design &Construction
The MOSTADAM D+C framework empowers new construction and major renovation projects
to achieve holistic sustainability by integrating resource-efficient design strategies, resilient
materials, and green construction innovations from concept through handover.
Holistic Site & Building Design
Early in the process, we optimize building
orientation, passive solar gain, and natural
ventilation to reduce heating and cooling loads.
Massing studies and envelope performance
modeling guide decisions on façade systems,
glazing ratios, and shading devices
Green Construction Practices
On-site protocols enforce strict wastediversion targets with dedicated sorting, reuse, and recycling streams. Dust-control measures, erosion management, and water-efficient construction techniques protect surrounding ecosystems.
MOSTADAM (O+E)
Building Operations &Existing
The MOSTADAM O+E framework focuses on elevating the performance of existing buildings
by refining operational practices, optimizing resource use, and embedding continuous
improvement—all without major capital overhauls.
Operational Optimization
Strategies
Leveraging low-cost, high-impact measures such
as tuning HVAC sequences,
retro-commissioning controls, upgrading lighting
to efficient fixtures we deliver measurable gains
in comfort and cost savings. Automated controls
and demand
Occupant Engagement & Training
Behavioral change is key to sustained
results. We design customized training
sessions for facility staff and tenant
workshops that promote energy-conscious
habits. Digital dashboards and awareness
campaigns empower users to participate
actively in the building’s green journey.
WELL
The healthy building difference
From initial goal-setting workshops to final certification and beyond, our WELL team
collaborates closely with architects, engineers, and facility managers. We translate scientific
research into practical design and operational strategies, leveraging advanced monitoring
tools to validate performance and continuously optimize occupant health.
Environmental Quality Assessments
Our specialists perform comprehensive air and
water quality testing, daylight/lighting audits,
and acoustic surveys to benchmark existing
conditions. These data-driven insights form the
foundation for your WELL prerequisites and
optimization strategies
Design & Construction Integration
We embed WELL requirements into design
documents and construction protocols
specifying low-emitting materials, circadiansupportive lighting, biophilic elements, and
ergonomic layouts. Continuous coordination
guarantees seamless compliance as the
project evolves
