Dear Alanna, Attached is my report on a comparison between sustainable sustainable building organisations, to guide in choosing and implementing sustainability sustainability in to a building. As the green movement grows so does controversy and biased opinions on how to build sustainable. I feel that this creates a lot of confusion and wasted time for someone trying to find reliable resources that contain easy to implement practices. I was interested in doing a comparison on what I consider to be the 3 big sustainable resources – LEED, Energy Star, and R-2000. This is not intended for learning about sustainability only for the implementation of sustainable practices. Three large are compared sustainable building programs of north America- LEED, Energy Star, and R2000. Are reviewed and analyzed on- the range of usability, scope of program, and the implementation process. This provides a resource to- developers, building teams and the public. This resource willintroduced various building programs, programs, aid in the choice in the most fitting program for specific building, and can be used as reference during construction. Only the 3 official websites for LEED, Energy Star, and R-2000 where used to complete this report I have learned the best locations for each sustainable building program and how to properly apply them to the construction of various building types

1  Introduction Three large sustainable building programs of north America ’: LEED, Energy Star, and R-2000. Are reviewed and analyzed on: the range of usability, scope of program, and the implementation implementation process. To provide a resource to developer’s, building teams and the public this resource will- introduced various building programs, aid in the choice in the most fitting program for specific building, and can be used as a reference when in construction. When buildingan a sustainable building the design team must first establish - sustainable objective, guide or implement organisations sustainable building program. LEED is one of the most well-known programs but LEED’s program is used only a fraction frac tion of the time when compared to older programs. All workers being properly informed in the construction industry is not only valuable but can be very cost effective. Green building is a combination of material, implementation, and correct use. This has created a massive problem within this industry. Everyone involved form the owner to workers and even the users need to understand how their role relates to the construction and use of a sustainable building. This will ensure that the objective is met and the building will perform as intended.

Self-motivation for this report is for a broader professional and personal understanding Self-motivation understanding of the major sustainable building programs. programs. As the green movement grow growss so does controversy and biased opinions on how to build sustainable. I this creates a lot of confusion and wasted time for someone trying to find reliable resources that contain easy to implement practices that will improve their building. I consider the 3 big sustainable resources – LEED, Energy Star, and R-2000. This is not intended for learning about sustainability only for the education of implementation of sustainable practices.

Each of the 3 programs includes - introduction that provides an understanding of the program, what the program includes, and the process of implementation. The programs are compared against the range of  usability, scope of program, and the implementation process.

This report will be an interest to the construction field and the general public. All workers in the construction industry will benefit from this report, pacifically higher management management.. Everyone will gain an understanding of the 3 large sustainable building programs- how they relate to the building, how the program works during construction construction and design, and what is needed and included to build to build to a particular standard.

This report does not focus on any specific building. Programs are only compared on what they achieve or focus on. My recommendation recommendation is for a general industry standard. standard. The problems and benefits benefits of each organisation are left to the reader to opinion Not all sustainable building programs could be included. Only 5 well developed and mature sustainable building programs where selected out of the vast number of programs, standards and concepts. Only information form the specific Organisations Website Website was included. This was to limit bias, opinions and distorted views/facts. views/facts.

2  Leed LEED (Leadership in Energy and Environmental Design) is an global organisation run by the USGBC (U.S. green building council) that can certify a building to prove it has high environmental standards. LEED uses a list of credits that most homes or commercial buildings can a can be designed to. A LEED certified professional will conduct a survey to award Credits for both the plans and the finished building if aspect of the are building meets criteria. Different set of credits arebuildings, available commercial, depending ofcore the and classshell, of building.  – new There 9 classes of the buildings construction, existing retail, schools, homes, neighborhoods, and healthcare buildings. Credits can be worth different amount of  points. There is a possible 110 points with minimum of 45 points to become be come LEED certified. 7 Categories’

of credits listed most to least possible points- Energy and atmosphere, sustainable sites, indoor environment, materials and resources, water efficiency, innovation, and regional priority. LEED buildings are designed to be more environmentally friendly by reducing impacts globally, locally, and internally. 1 Figure 1

2.1  LEED certification 2.1.1  9 rating systems LEED has 9 rating systems that each focus on a different type of building with differ different ent uses, this creates flexibility so that all types of buildings have a fair chance a obtaining a LEED certification certification and to better focus on the specific problems and areas for improvement of each building. 9 building categories New construction and Major Renovations, existing buildings, core & shell,

commercial interiors, retail, homes, neighborhoods, schools, and healthcare. 8

 

  Downloadable hundred page pdf documents for each of the 9 rating systems. Appendix 1 2 

New construction and Major Renovations “LEED for New Construction addresses design and construction activities for both new buildings and major renovations of existing buildings, which includes major HVAC improvements, significant envelope modifications, and major interior rehabilitation.” 3  Existing Buildings

The rating system encourages owners and operators of existing buildings to implement sustainable practices and reduce the environmental impacts of their buildings, while addressing the major aspects of ongoing building operations:4  o

  exterior building site maintenance programs

o

  water and energy use

o

environmentally ally preferred products and practices for cleaning and alterations   environment

o

  sustainable purchasing policies

o

  waste stream management

  ongoing indoor environmental quality Core and shell LEED Core and shell are buildings that will be leased/ rented by a tenant that will modify the interior space such as a office building. Only mechanical, electrical, plumbing and fire protection systems will be certified. This is intended to allow a developer to build to LEED standards without forcing the tenant to do the same or the building could not pass certificat certification. ion. This is designed to work in tandem with 5 commercial interiors   Commercial interiors LEED for Commercial interiors gives tenants that lease space in a building the freedom to design their internal space to LEED standards when they have no control over existing structure or mechanical systems. Example of this situation is tenants in office buildings, tenants are only allowed to modify interior finishes. This is designed to work in tandem with core and shell.6 

Homes  LEED for homes is designed to- reduce environmental impact, energy use, improve indoor environment by minimizing toxins in building materials and reduce the operational cost of the home.7  Neighborhood Development Development neighborhood planning can limit the need for automobiles and create pedestrian-friendly streets by encourage walking, bicycling and public transportation.8

Schools “The LEED for Schools rating system was developed to address the design and construction of K-

12 schools. Based on LEED for New Construction, it focuses on classroom acoustics, master planning, mold prevention, environmental site assessment” 9

2.1.2   Alternative Compliance Compliance Paths (ACPs) “Alternative Compliance Paths credits provide additional options or approaches that address

unique circumstances and accommodate advancements in science and technology. ACPs allow LEED to be more more flexible and applicable to a wider range of projects. ACPs can be applied at the discretion of the project team, based on applicability; they are not mandatory for any project. “ 10

 

2.1.3  Points Rating systems are broke up in to 5 main credit categories- Sustainable sites, Water efficiency, Energy & atmosphere, Materials & resources, and Indoor environmental quality. There are 2 bonus

categories Innovation in design/operations credits, and Regional priority credits. Also there are 10

 

  additional categories for Neighborhood Developme Development, nt, and Homes.11 http://new.usgbc.org/leed/ratingsystems   systems Figure 3 each of the credits list- how many points its worth, what the credit is intended to do, and requirement that are needed to be awarded that credit. Shown in figure 2 a list of all possible credits for each of the construction types and in each of the 5 main categories can be reviewed on the LEED website12 appendix 2

Categories are made up of credits that each have a different intent to improve the building. Most credits are worth 1 point but can range up to 24points( EAc1 Optimize energy performance). Credits that have a large impact on energy efficiency, and reduction in carbon dioxide emissions carry the most points. The amount of points that are obtained are used to determine what level of LEED was achievedcertified40-49, certified40 -49, silver50-59, silver50-59, Gold 60-79, platinum 80+out 80+out of a possible 110points. To qualify for certification All Buildings must meet minimum program requirements (MPR) and all prerequisite credits. Both MPR’s and prerequisite credits are not worth points. 

2.1.4  Minimum program requirements (MPR) There are 7 Minimum program requirements- comply with environmental laws, be a complete and permanent building or space, use a reasonable site boundary, comply with minimum floor area requirements, comply with minimum occupancy rates, commit to sharing whole-building energy and water usage data, comply with a minimum building area to site area ratio. 13 Explanation of each each credit can be ffound ound at appendix 3

2.2 

Certification processs When LEED is chosen for a building the owner must First higher a team of LEED accredited professionals. This team will- aid in design, and manage the LEED approval process on top of  14

their regular management.   Higher LEED accredited professiona professionals ls before major design of the building begins. An green rater, an

architect and 1 employee on the construction management team must be a LEED GREEN ASSOCIATE

Determine which rating system you will use and prepare your certification application. Applications Applications

differ depending on your building type and the LEED credits. Register your project. The registration fee for a project is $900 for USGBC members and $1200 for non-

members. Submit your certification application and pay a certification certification review fee. Fees differ with building type

and square footage. Await the application review.

Receive the certification decision, which can be accept or appeal to increase the building score. An

affirmative decision signifies signifies that your building is now LEED certified and the building will receive an certificate and plaque to be mouthed at the main door of the building. 2.2.1  Guidance To aid in the selection of the appropriate appropriate rating system LEED has a 3 step guide to narrow down witch rating system your building fall under; construction type, space usage, and percentage of 

building Not all buildings an obvious rating but system. is a 40/60 floor area rule to decidearea. the building categorywill if 2 have buildings are attached someThere buildings may be excluded from all rating systems because of some Exceptions.16 3 step guide and Exceptions can be found on appendix 4

2.2.2  Homes certification Before registering your project, your project manager will select a “LEED for Homes Green Rater”. Your green rater will first make a preliminary rating of the early design and ensure the project team understands what is needed to become certified. The project team can start design and build your project after you register. During construction your green rater will work with your team ensuring everything need for certification is properly documented. You will apply for certification when the project is complete. Table

3  Energy star ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. ENERGY STAR rates and certifies both products and Buildings. As of January 1, 2012 17 The new ENERGY STAR Version 3 of building certification has come into effect for all types of constructionconstruction- new 18 homes, Full renovations, buildings and plants. Currently 200,000 buildings across the USA are ENERGY STAR certified Energy STAR uses a Checklist filled out by- an ENERGY STAR rater, an Contractor, and a Builder to Determine Determin e if a building is Certified. Additionally performance of each of the building’s systems will be tested to determine the energy efficiency value. Energy stars focus is primarily on efficiency performance performance but also includes quality control to ensure lasting performance. performance. The program will aid in the design but relies on the final inspection of performance and quality of work. Each of the four checklists has a quality quality guide for inspector use. This ensure ensuress that the building was built correctly.

3.1  Energy star check lists 3.1.1  Home v3 Both single and multifamily homes are eligible for an ENERGY STAR rating. Multifamily buildings

have size restrictions and needs to be 4 units or fewer. See Appendix 5 for full details on restrictions. Multifamily buildings that don’t meet the restrictions may be eligible through the Multifamily High Rise

Program.19  There are two paths to becoming certified - Prescriptive Path, and the Performance Path. The Prescriptive Path is a single set of measures that are easily used to rate a home but does not have flexibility flexibili ty to be used on every type of home. The national program requirements are used to certify buildings. The U.S.A is broke up in to 8 climate zones. Depending on what zone a building is in will decide how the building is tested.20 Map of climate zones can be found in Appendix 6

The Performance Path allows for lots of flexibilit flexibilityy in a building to select a custom combination of  measures. A rater must calculate the greatest HERS Index of the building to use this path. A HERS index is a combination of all of the thermal and energy efficiency’s in a building. thermal resistance and thermal gain of- Foundations, floors, walls, doors, windows, ceilings, attics, and roof. energy efficiency of  the buildings systems- Heating system, cooling system, water heating, Thermal distribution(ducts and pipes),thermostat, pipes),ther mostat, infiltration infiltration & mechanical ventilation, lighti lighting ng & appliances, and internal gains & 21 internal mass for an in-depth look see Appendix 7 for details.

All buildings must go through 4 quality control checklists for- thermal Enclosure, heating/ Ventilat Ventilation ion & air conditioning, and water management. Quality control is done by the Rater, contractor and Builder. Every checklist has a checklist guide to help standardise quality throughout the industry and to ensure that every building building will perform perform as designed. Each section of the guide outlinesoutlines- what is being examined, who should of performed the work, requirement charts, and Images of both proper and 13

Efficiency (OEE) of Natural Resources Canada (NRCan)26  “The R-2000 Standard sets out the criteria that a new home must meet in order to be eligible for

R-2000 certification. The technical requirements involve three main areas of construction: energy performance, performance, indoor air quality and environmental responsibility.” 27  Detached houses, attached houses, and multi-unit building can all be certified

15

 

 

There is no additional cost in building an R-2000 home. All r-2000 professionals involved are in place of  non- certified professionals

The R-2000 standard is a small 16 page booklet of criteria that a house has to meet to become eligible for R-2000 certification appendix 15. This standard is written simply. R-2000 does not give specifics on how the building should be built but is rated on the ability to meet the intents of the requirements. requirements. Three R-2000 service providers will perform the certification- R-2000 Plan Evaluator, Evaluator , R-2000 Inspector, R-2000 Airtightness Tester. Service providers use a R-2000 Procedure manual that contains checklist of  all the information required to become certified. Appendix 16

3.3 

R-2000 building standard

There are 5 sections of criteria; Building envelope – minimum performance performance of outer walls and roof of building Mechanical systems - restrictions restrictions on equipment Energy performance - efficiency requirements Indoor air quality – avoiding indoor toxic air pollutants Water conservation – maximum flow rates of fixtures

Building Envelope Building envelope covers insulation, air tightness, and windows. Insolation levels only have to meet the local building code but also most of the basement basement has to be insulated. Performan Performance ce of insolation will be tested once the building is finished to confirm the house meets the energy target. Section 6 R-2000 Energy performance Targets. Energy target testing is conducted by a R-2000 plan evaluator using energy calculation software Hot2000. Calculation of the Annual Energy target uses 2 equations added together and multiplied by 0.5 and with the house set at standard conditions appendix 17. The 2 equations are for annual space heating and annual domestic hot water. Annual space heating formula uses- heating value depending on the type of heating (fuel o orr electric), local degree days and the volume of the house. Annual hot water formula uses- heating value depending on the type of  heating (fuel or electric), and local water main temperature. temperature. Air tightness test can be done through pressurisation pressurisation or depressurisation. depressurisation. The building should have a less than 1.5 air changes per hour when pressurised to 50 Pascal or depressurised to 10 Pascal and measured with CAN/CGSB-149.10-M86 from the Standards council of Canada. When testing a multi-unit building each unit should be tested individually. Windows that are energy star qualified meet or exceed the R-2000 requirements. Decorative windows such as windows in doors, stain glass and other specialty glass are allowed if the total speciality glass area is less than the total glass area or the building. Mechanical systems 16

 

 

Mechanical systems are the primary energy consumption and greenhouse gas creators of a building such as- heating and cooling, ventilation, and wood burning appliances. appliances. Any type of system is available to use but must meet or exceed energy targets. Section 5 R-2000 Mechanical systems heavily focuses on the proper ventilation of each type of system to avoid indoor air contamination. contamination.

Water conservation Water is conserved through fixtures and the choice of 2 environmental features from the R-2000 pick list Appendix 18 low flow toilet, shower and lavatory faucets fixtu fixtures. res. Toilets should flush with less than 4.8 litres. Low flow Shower heads should use less then7.6 liters/min tested at 80psi. lavatory faucets should use less than 5.7 litres/min tested at 60psi.

Pick list R-2000 has a Pick list appendix 19 that allows the owner to decide which which Indoor air quality and Environmental features they wish to incorporate into the building. A minimum of 3 of the 9 indoor air quality features and 2 out of 14 Environmental Features are needed. Indoor air quality features focus on toxic off gassing of materials but also includes moisture control, and air filtration. Indoor Air Quality Features list- Carpeting, air filtration, paints and varnishes, flooring adhesives, cabinetry, vinyl flooring, particleboard underlayment, underlayment, sub-slab in depressurisation, depres moisture control. cont A wideinsulation, range of  sustainable practices can be achieved the 4surisation, categories categoriesand of environmental environment alrol. featuresSheathing/drywall, interior framing and trim, and reduction in energy use. Theses environmental features focus on recycled materials and energy use.

R-2000 Process

A R-2000 builder should be hired first Before plans are created. A R-2000 builder will act as a guide through the process to ensure- Plans, documentation, and the finished building all meet the criteria. Plans will be created that incorporate all necessary items listed in The R-2000 standard. Plans will be evaluated by a R-2000 plan reviewer. The builder can now start construction of the building. R-2000 28 houses must builtaby certified builders. A builder can become a licenced builder if they attend a 2 day workshop andbebuild demonstration demonstrat ion home.  

During construction before the house is dry walled a R-2000 inspector must inspect the building to insure the building is built to the provincial building code and all R-2000 features where installed correctly. After the building has been fully completed- sealed, dry walled , and painted. A “NRCan” licenced company can be hired to conduct air tightness testing. After a home has passed all tests and documentation has been collected by the builder and sent to R-2000 a R-2000 certificate will be issued to the homeowner. People involved in performing certification are- R-2000 builder, R-2000 Plan reviewer, R-2000 inspector, and “NRCan” licenced airtightness tester.

4  Conclusion LEED (Leadership in Energy and Environmental Design) is an global organisation run by the USGBC (U.S. green building council) that can certify a building to prove it has high environmental environmental standards. 9 building categories that are eligible for certification are- New construction and Major Renovations, existing buildings, core & shell, commercial interiors, retail, homes, neighborhoods, schools, and healthcare.

Rating systems are broke up in to 5 main credit categories- Sustainable sites, Water efficiency, Energy & atmosphere, Materials Materials & resources, and Indoor environmental environmental quality. Categories are made up o of  f  credits that each have a different intent to improve the building and are worth points. The amount of  points that are obtained are used to determine what level of LEED was achieved- certified40-49, silver50-59, Gold 60-79, platinum 80+out of a possible 110points. Additionally there are 7 Minimum program requirements not worth points. To begin Higher LEED accredited professionals professi onals before major design of the building begins. A green rater, an architect and 1 employee on the construction management team must be a LEED GREEN ASSOCIATE During construction your green rater will work with your team ensuring everything needed for certification is properly documented

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. ENERGY STAR rates and certifies both products and Buildings Energy STAR uses a Checklist filled out by- an ENERGY STAR rater, an Contractor, and a Builder. The focus is primarily on efficiency efficiency performance but also includes quality control to ensure lasting performance of both homes and buildings. All buildings must go through 4 quality control checklists forthermal Enclosure, heating/ Ventilation & air conditioning, and water management

ENERGY STAR has commercial rating systems for- government, healthcare, higher education, hospitality/ entertainment, industrial, K-12, Real estate/multifamily, retail, small business, congregations, service & products providers, utilities & energy efficiency program sponsors, water/ wastewater utilities. Hire ENERGY STAR qualified professionals- Rater, Builder and Contactor

R-2000 Collaboration between the Canadian Home Builders’ Association (CHBA) and the Office of Energy Efficiency (OEE) of Natural Resources Canada (NRCan requirements involve three main areas of  construction: energy performance, indoor air quality and environmental environmental responsibility. Detached houses, attached houses, and multi-unit building can all be certified R-2000 Plan Evaluator, R-2000 Inspector,, R-2000 Airtightness Tester. Service providers use a R-2000 Procedure manual that contains Inspector checklist of all the information required to become certified. Checklists that -Building envelope, Mechanical systems, Energy performance, performance, Indoor air quality, and Water conservation all meet high standards. 18

 

 

A R-2000 builder will act as a guide through the process to ensure- Plans, documentation, and the finished building all meet the criteria. People involved R-2000 builder, R-2000 Plan reviewer, R-2000 inspector, “NRCan” licenced airtightness tester

5  Recommendations It is recommended that all 3 sustainable building practices be thoroughly considered for every building. Each of the building practices practices focus slightly more on a important sustainability feature. Choosing LEED will aid in including the latest high performance construction technology. Energy star will drastically improve Energy efficiency and quality, and R-2000 is a cost-effective way to have high performance homes.
