We specialize in building performance services covering the entire lifecycle of buildings. Our team collaborates with client partners to develop innovative solutions for high-performance buildings that are durable, comfortable, and inexpensive to operate.

Building Performance Services

Daylight Modeling

Our team provides modeling and consulting services to help clients optimize daylighting in built environments to create a connection to the outdoors for building users, maintain circadian rhythms, reduce glare, and optimize controls for energy efficiency.

Water Modeling

With increasing cost and limitations on water use and wastewater production, water efficiency is becoming extremely important for many building owners. Our comprehensive approach to facility water consulting begins with a water audit, with the potential for a water efficiency investigation, efficiency implementation, and ongoing periodic water consulting services.

Energy Audits

An engineering energy audit/analysis strives to help facility managers and owners of existing buildings understand their building’s energy use characteristics while providing recommendations for energy and cost savings. This process offers a chance to benchmark performance against peers through the ENERGY STAR Portfolio Manager Tool. Following the guidelines provided in ASHRAE’s Procedures for Commercial Building Energy Audits, an owner can choose between Level I (Walk-through Analysis), Level II (Energy Survey and Engineering Analysis), or Level III Energy Audit (Detailed Analysis of Capital Intensive Modifications).

Resiliency Assessments

Building owners face many challenges in the long term reliability of their properties and campuses. We have deep expertise in assessing the resiliency of buildings and infrastructure to a range of factors including climate change, grid disruptions, and extreme weather events. We consult to our clients on potential risks and mitigation measures to help increase the sustainability of their portfolios.

Monitoring Based Commissioning

Monitoring based commissioning (MBCx) integrates energy system monitoring with real time feedback, providing actionable equipment and system performance information to facility managers. Our team utilizes MBCx to facilitate identification of unusual system function or energy use patterns and detection of faulty equipment operations, with the goal of maintaining system functions and energy efficiency over time. When implemented on a recently completed building, MBCx assists in preventing performance decay and potential risk mitigation associated with operations and equipment function issues. As part of MBCx, we use cloud-based Automatic Fault Detection and Diagnostics (AFDD) software to help our clients optimize their buildings on an ongoing basis.
