About CSI Engineering

We opened our doors in 1996, founded by a Wentworth Institute of Technology graduate named John E. Cass. CSI Engineering started with an extreme focus on assisting general and mechanical contractors with creating coordination and as-built drawings within small- to large-scale design projects. 

CSI Engineering has since moved locations from Saugus, Massachusetts to Portsmouth, New Hampshire — our headquarters for serving New England and beyond. We have broadened our attention to serve architects, developers and contractors with comprehensive capabilities, including HVACElectricalPlumbing and Fire Protection Engineering services.

Benefits of Having a LEED-Certified Building

Considering having your building LEED certified? Explore some of the advantages of investing in this certification: 

  • Help the environment: Energy-efficient buildings are the way forward for the global community, reducing up to 34% of carbon emissions, diverting over 540 million tons of waste from landfills and decreasing pollution to resolve climate change. 
  • Achieve business goals: LEED buildings are better for business, helping investors achieve ESG goals, boost efficiency and lower operational expenses. 
  • Take care of your people: Developing a greener building will create a beneficial space with healthy air and plenty of sunlight that your employees and visitors will appreciate. 
  • Attract well-paying tenants or buyers: LEED-certified buildings tend to achieve higher rents than non-certified spaces and even attract premium prices when put on the market.

LEED Certification Process

LEED certification is the gold standard for green building design, created by the U.S. Green Building Council in 1993. By following a specific rating system with certain prerequisites based on the building type, your building can earn a LEED certification. Not every project type follows the same guidelines, so using the right rating system for your project — such as Building Design and Construction, Homes, Neighborhood Development, and Cities and Communities — is crucial. 

These rating systems focus on various areas, including: 

  • Sustainability 
  • Integration 
  • Location and transportation 
  • Water efficiency
  • Materials 
  • Energy and atmosphere
  • Indoor environmental quality

Certification Levels

LEED certification uses a point-based scale. The more successful you are in adhering to the rating system, the more points you will collect. Using energy-efficient lighting or implementing effective waste management procedures are basic steps to boost your certification. Buildings can earn up to 110 total points but can achieve certification with point totals such as: 

  • Certified: 40-49 points
  • Silver: 50-59 points
  • Gold: 60-79 points
  • Platinum: 80+ points 


Here are some of the most popular questions regarding LEED consulting and certification. 

What Does a LEED Consultant Do? 

LEED consultants oversee your building process from design to construction. They provide valuable insight into how best to implement green strategies that balance cost efficiency and environmental performance. Reliable professionals understand the latest criteria and approaches to develop an eco-friendly design that receives high point tallies on the LEED certification scale.

How Much Does LEED Certification Cost? 

LEED certification expenses vary across projects and depend on the size and intricacy of the build or renovation. You’ll likely have to pay fees for registration, certification, consultancy services and testing. Our CSI Engineering experts can give you a clearer picture of what you can expect to pay during the process. 

How Do You Choose the Right Rating System? 

Review rating system descriptions and your project scope to determine which guidelines are best for your situation. The U.S. Green Building Council recommends following the 40/60 rule when you believe multiple systems apply. 

Is LEED Certification Worth It? 

LEED certification adds significant value to your property. Green and energy-efficient buildings are unique assets investors and tenants want to see in their communities. Certification will ensure you do your part for the environment, enjoy financial benefits and join a globally recognized group of organizations paving the way toward a new future.
