What We Do

 

Sustainability Strategy

Achieving better-than-industry performance requires having a team committed to better outcomes and knowing where to shift the supply chain. To create this focus, we:

  • Benchmark leading solutions for managing carbon, energy, health factors, durability and materials

  • Implement practical measurement, tracking and reporting processes that align with client processes.

  • Communicate targets, solutions and outcomes that inspire stakeholders and the broader market

We combine extensive knowledge from existing facility performance evaluation and new development design and construction review.

Performance Analysis

Properly applying the appropriate metrics and tools ensures you achieve the desired performance over the appropriate timeframe. To establish the outcomes, build commitment and remove barriers through planning and design, we:

  • Define performance targets based on predictive modelling and experience with existing building operations and economics 

  • Develop design solutions using energy, daylight and thermal modelling and parametric, generative algorithms

  • Provide guidance to keep project teams focussed and on schedule.

 

Asset Improvement

Sustainability performance is increasingly important for even gracefully aging real estate assets. To achieve the full potential of a facility through each stage of planning and implementation, we:

  • Identify and realize opportunities through Audits; Recommissioning; Tune-ups; Deep Retrofit Analysis; and advanced Energy Management services.

  • Define sustainability targets and metrics; and integrate into design, procurement and construction

  • Manage certification compliance for LEED, WELL, Energy Star, Zero Carbon Building Standard, etc.

Portfolio Programming

Maximizing portfolio value involves identifying the best opportunities for performance improvement and optimizing implementation. We develop solutions through:

  • Management process design to align portfolios with sustainability mandates

  • Strategies to (re)position assets, engage stakeholders and confirm success through rating systems

  • Technical support to operationalize and implement selected strategies

  • Performance measurement and communication to make success clear to different audiences.
