Green Rater: the new kid on the LEED block
by Tyler Hermanson, LEED AP+H, LEED Faculty
You may have heard the terms "Provider" and "Green Rater" in relation to the LEED Canada for Homes program – but what do they do and how do they support sustainable building in Alberta?
In short, Providers are the organizations that administer the LEED Canada for Homes program locally, completing the final project review and ensuring all required submissions are made to the Canada Green Building Council.
Green Raters are the technical side of the inspection verification team. They report to the Provider, helping the project team throughout the project and completing the on-site inspection work.
"This system provides a triple check system of verification for LEED homes. The Green Rater checks the builder and trades; the Provider checks the Green Rater's work and the CaGBC checks all projects submitted by the Provider."
The system encompasses various business models for the relationship between Provider and Green Rater. Some Providers like me are also qualified as a Green Rater. I have other in-house Green Raters and am also looking at contractor Green Raters.
Other Providers have no in-house Green Raters and use contractor for all inspections.
"The role of a Green Rater isn't always clear for builders and those new to the program. A Green Rater is part consultant, part inspector and part file manager. We act as a key point between the building project team and the CaGBC and Providers who certify the home."
A Green Rater:
- helps projects navigate the LEED process and requirements, offering clarification and additional information (for example, offering advice on proper features for good Radon sealing when protecting foundations from sub-soil gasses),
- completes visual inspections and reviews support documentation to ensure all credits are verified (for example, completing required inspections for insulation during construction and final inspections upon completion),
- collects documentation and accountability forms from the project team, often the builder or architect, and compiles them into a package for submission (for example, project teams have several required accountability forms and signatures in all LEED projects, and some credits required additional signoff),
- signs off on the LEED project as compliant with the standard before quality assurance and auditing by the Provider and CaGBC (for example, Green Raters must approve a project as compliant and meeting the certification levels before a project is submitted for certification).
A good Green Rater will not act as the "Green Police" on a LEED Canada for Homes job site but, more importantly, as an educator and resource for project teams to use as they move through construction and certification.
Current Green Raters come from a variety of backgrounds but they will have experience in residential construction and high-performance, sustainable building practices. Some are technologists or engineers, often with a background in EnerGuide or R2000 construction.
Often Green Raters have additional credentials as Certified Energy Advisors with EnerGuide, ventilation training through HRAI and additional building science or building investigation training. They have valuable experience with LEED and energy-efficient building techniques and they can be of considerable help to project teams working toward LEED certification.

Interested in becoming a Green Rater?
The process starts with a single step – approaching your area's LEED Provider.
Alberta has two Providers - Alberta Chapter – CaGBC members Tyler Hermanson of 4 Elements in Calgary and Stephani Carter of EcoAMMO in Edmonton .
Providers do not have fixed territories, but its often best to work with your nearest Provider.
After you start the process, Tyler or Stephani would review your credentials.
There is no formal training or exam for Green Raters in Canada so acceptance is up the Provider.
Green-Raters-In-Training would then start a mentorship / shadowing process with an experienced Green Rater. It is expected that Green Raters will at minimum pass their LEED AP+Homes shortly after completing their mentorship. As the program continues to grow, the need for additional Green Raters will increase, especially in outlying areas or smaller city centres such as Red Deer, Medicine Hat and Grande Prairie.

LEED Canada for Homes – an overview
The LEED Canada for Homes program was launched in March 2009, the newest LEED certification suite on the market.
Since its inception, the program has certified more than 400 Canadian homes and multifamily projects with more than 2,100 projects registered.
In Alberta, 221 single-family homes and 37 multifamily homes are registered with the LEED Canada for Homes program.
LEED Canada for Homes is built on the same model as other LEED programs so the intents, credit areas and checklist will be familiar to existing LEED APs.
Some significant differences, however, simplify the program to match the smaller scale of single-family homes and their construction process.
Unique features of LEED Canada for Homes include:
- the use of local Providers to promote, administer and organize projects regionally,
- the requirement of on-site inspections by a LEED Green Rater during and after construction,
- the requirement for very little documentation to be submitted to the CaGBC,
- the speed of certification, typically only two weeks once documentation is submitted, and
- significantly lower certification costs , often as low as $2,000 per home or $650 per unit on larger multifamily sites.

A different Elbow Valley home
With a 7,000-square-foot house and a 2,000-square-foot garage, the environmental footprint of this Rocky View County home must be huge. Right? Wrong.
A Calgary couple are building an impressive two-storey home, situated in the Elbow River corridor on 1.1 acres next to a four-acre municipal reserve and a children's playground. While the architectural appeal of the home is apparent at first glance, the homeowners are equally excited about the possibility of their nearly completed home achieving LEED certification.
With an impressive range of sustainable features, and help from Green Rater and Home Provider Tyler Hermanson, the Calgary couple included the following features in their home to ensure solid construction while meeting their objective of building an environmentally conscientious home:
- a large roof solar panel array that meets 100% of the household's electricity needs,
- Insulated Concrete Forms (ICF) that allow for thermal mass in the lower level of the house for increased energy efficiency,
- prefabricated, factory-built insulated main floor walls that deliver an R38 insulation factor while reducing onsite construction waste,
- Pinkwood engineered i-joists, dimensional lumber and wall and roof sheathing that provide fire protection as well as moisture and mould resistance to all the wood framing and floor systems,
- a high-efficiency natural gas-fired boiler system,
- an in-floor radiant heat system that provides baseline heat in cold months,
- triple-glazed, low-energy windows,
- a dual heat recovery ventilation system, and
- a hot water circulation pump,
- automated lighting, heating, water sensor and security controls with features controllable remotely by iPhone, and
- disposal of construction waste through recycling.
Outside, the project is focusing on a sustainable landscape design with naturalized and permeable features including a high-efficiency irrigation system.
"We are particularly proud of our use of the Pinkwood products for our floors, walls and roof," said the owners. "Pinkwood engineered wood improves the air quality of a house by eliminating the potential of mould. We are also very pleased that our solar electricity system can take advantage of Alberta's micro-generation rules to allow homeowners to sell electricity to the grid."
Alberta's micro-generation rules came into effect January 1, 2009, significantly simplifying the grid connection process for micro-generators such as these homeowners. The regulation allows offsetting the site energy consumption with the energy generated on site, so-called net metering.
Construction of the home, started in June 2011 and nearing completion, has been an intensive undertaking.
Has it been worth the challenge?
"Going green is easier than most people think. Homeowners have to do a little research and educate themselves about the myriad ways to produce an environmentally friendly home while being able to finish a home in the style and design of their choice. There are some great, cost-effective consultants in Calgary who can help people understand what green elements are important, what they cost and how to set priorities among the options," explains the couple.
"We are amazed how quickly some green elements literally pay for themselves. It was also important for us to incorporate these features in our home as a way to set an example for our three young kids of how to respect limited natural resources in everyday life."
The owners have become huge advocates for green. "Our experience is that one can build an architecturally stylish home while achieving important environmental efficiencies with just a little planning.
It is clearly possible to achieve good returns on investment from electricity and heating savings with green elements such as solar panels, heat recovery units and higher insulation values.
"We would urge those families interested in an environmentally efficient build or renovation to take some time to research environmentally conscientious features to determine what they believe to be important, then contact energy efficiency and/or LEED consultants to help them build a sustainable house they will love and be proud of."

Welcome to my (near-net-zero) home!
Edmonton architect Shafraaz Kaba took the "doors open" part of the recent Historic Festival & Doors Open Edmonton event literally.
The Kaba home was one of the listed private residences open for public viewing during the July 3-8 festival.
The Beverly Heights net-zero-ready home on Ada Boulevard was described as "an experiment in the reuse and reclamation of materials, a passive-solar design and creating a unique, sustainable example for redevelopment in a mature neighbourhood."
It was a busy place with individuals examining the many features of the unique home and then enjoying the wonderful river valley view from the second storey balcony.
While some finishing remains, Shafraaz is particularly proud of the following features:
- designed around a passive solar strategy using low-tech solutions to achieve a high performance result,
- the most high-tech part of the house is a 4.8 kW solar PV system,
- the innovative reuse of materials including church pews as window seats and door casings, fridge doors as pantry doors and reclaimed gym flooring in a randomized pattern,
- testing carbonized wood for durability and colour steadfastness for our climate, and
- the small ground footprint for a relatively large edible garden/permaculture.
