Designing and operating an efficient, sustainable building helps you cut operating costs, increase property value and enhance your environmental credentials to stand out in the marketplace. Green building rating systems reward high performers who set themselves apart from their peers. DNV GL has a team of sustainability consultants who specialize in assisting clients in achieving such certifications as:
- Leadership in Environmental Design® (LEED®) – one of the most respected and widely-used green building rating systems in the world
- Living Building Challenge® – considered the most challenging green building rating system
- WELL® – a specialized rating system focused on healthy interior environments
- ICC 700 National Green Building Standard™ (NGBS) – The American National Standards Institute (ANSI)-approved rating system for residential projects
Each rating system varies in certification requirements, and our expert team creates a customized and seamless path to certification for our clients, often exceeding their expectations. Most of our LEED certification projects have achieved Gold and many have even reached Platinum.
DNV GL offers strategic and technical advisory services to help our clients manage risk and achieve sustainability targets across a single building certification, or portfolio of buildings. With more than 30 years of experience in in energy project management, onsite generation, energy efficiency and procurement, demand management assessments, and renewable energy and carbon markets, we have been the lead sustainability consultant on more than 150 green building certification projects around the world. Our services include:
- Whole-team Design Charrettes to brainstorm and vet out design considerations to meet both the certification goals overall project goals
- Project Management of the design team along the spectrum of involvement with the certification documentation
- Energy Modeling: [LEED NC EAp2/EAc1] Whole-building energy analysis is a dynamic annual computer simulation that accounts for climate conditions and all elements of the building: thermal envelope, HVAC, lighting, and occupancy levels and schedules. This powerful energy model forecasts annual energy consumption and operating costs to inform design at any stage of a project.
- ENERGY STAR® Portfolio Manager Benchmarking: [LEED EBOM EAp2/EAc1] The Energy Star Portfolio Manager on-line tool helps building owners track and assess energy and water consumption within individual buildings as well as across entire building portfolios. The ENERGY STAR rating system uses a scale between 1 and 100, by comparing each building with statistically representative models derived from similar buildings from a national survey conducted by the Department of Energy’s Energy Information Administration.
- ASHRAE Level 1 and Level 2 Energy Audits: [LEED EBOM EAp1/ EAc2.1] The Level 1 audit is a walk-through audit with preliminary analysis. It includes a site visit followed by analysis and a report which contains a list of no-cost/low-cost and capital measure recommendations, and estimated energy and cost savings for each recommended energy conservation measure (ECM). The Level 2 audit is more in-depth than the Level 1. It includes everything from the Level 1 plus further analysis on implementation costs, operating costs, and achievable savings for each ECM; detailed energy and cost savings, payback period, increased asset value, and ROI for each ECM; and a list of additional benefits to operation and maintenance, occupancy comfort, incentives, and lifecycle.
- Commissioning: [LEED NC EAp1/EAc3] Energy strategies matter, but validating performance after construction is critical to achieve the promise of efficient design. Our experienced commissioning agents will make sure your high performance design operates at peak efficiency, maximizing return on investment.
- Renewable Energy Calculations: [LEED NC EAc2] Renewable energy can be used to offset the annual energy consumption of a building (based on actual utility bills or estimated from energy modeling). Our engineers work with our clients to optimize the size of solar arrays, for instance, to meet their needs and maximize value.
- Minimum Outside Air Calculations: [LEED NC IEQp1/c2 & LEED EBOM IEQp1/c2] This calculation establishes a baseline for providing a minimum amount of outdoor air to buildings in order to maintain good indoor air quality and keep occupants comfortable and healthy, per ASHRAE 62.1-2007.
- Thermal Comfort Analysis: [LEED NC IEQc7.1 & LEED EBOM IEQc2.3] Thermal comfort is a measure of how comfortable the indoor environment is perceived to be by its occupants. Thermal comfort modeling is used to give an indication as to the proportion of occupants who notice warmth or coolness in a space. As the proportion of occupants noticing a certain thermal environment (such as warmth or coolness) increases, the level of thermal comfort deteriorates. Where level of “dissatisfied” occupants is low, the level of thermal comfort is considered to be good. As a result, a thermal comfort analysis of an interior environment assesses a number of environmental parameters. These parameters include air temperature, mean radiant temperature, air velocity, and relative humidity within the space.
- Daylighting Simulation and Analysis: [LEED NC IEQc8.1 & LEED EBOM IEQc2.4] Daylighting uses indirect sunlight to illuminate interior spaces and reduce the run-time for artificial light systems. Effective daylighting requires proper design placement of apertures and windows, and natural light must be blended seamlessly with interior lighting systems to achieve proper illumination. Too much direct sunlight can create glare or increase heat gains. Daylight modeling involves a 3D model that analyzes the quality of natural light entering the space directly and indirectly and evaluates luminance levels on the surfaces and objects as a result. Hourly, month and annual studies can all be done to produce the best evaluation of daylight harvesting.
- Visual Comfort Glare Studies: [LEED NC IEQc8.1 & LEED EBOM IEQc2.4] Visual comfort studies allow us to evaluate potential glare conditions that might impact occupants within the space. These glare studies help us to determine the optimum window placement or shading device locations, or even the most beneficial window glazing.
As a result of our extensive history working with the Green Building Certification Institute (GBCI), DNV GL has been granted Proven Provider status, which allows for expedited LEED reviews and direct contact with GBCI Reviewers.

Members of the Sustainable Buildings and Communities (SBC) team have a wide variety of relevant expertise to draw upon for LEED projects. The group has experience and professional degrees in architecture, mechanical and electrical engineering, landscape architecture, city planning, property management, and general construction. This diversity of experience gives the team a well-rounded view of the industry from multiple perspectives (planning, designing, building, managing, etc.) and scales (individual residential and commercial buildings, portfolios of buildings, cities, etc.). They have led the technical development of many high-performance and zero net energy buildings, advising on energy systems, water efficiency and reuse, material impacts and healthy interiors. Additionally, many members of the SBC team have worked as GBCI LEED Reviewers for both LEED BD+C as well as LEED O+M reviews. The SBC team holds the following accreditations:
- Licensed Architects and Professional Engineers
- U.S. Green Building Council (USGBC) LEED Faculty
- LEED Accredited Professional for Neighborhood Development (LEED AP ND), Buildings Design & Construction (LEED AP BD+C), Homes (LEED AP Homes) and Existing Buildings Operations & Maintenance (LEED AP O+M).
