Here are the new enumerations.
The NGBS Single-Family Certification has Bronze, Silver, Gold, or Emerald certification levels. I don't know if the Land Development and Multifamily would be relevant or not for the scope of HPXML. |

I added gold, silver, bronze, emerald to the appropriate NGBS certifications and removed the land development one because it doesn't seem to be relevant.

I suggest we break these out into three separate fields:
This would let you cut down on the number of enumerations for each, and probably be easier to maintain. I hear this is what the RESO dictionary does. Here is an excerpt that adds some justification for the status:

Here are some additional ones we came up with: And along with my previous comment, we think there might be levels within each of these already proposed ones: Living Building Challenge Petal Certification |
Here are my current thoughts on this matter: Breaking into 3 different fields@brandongallagher's comment about breaking this into three different fields (certification/organization, level, status) is a good one. That is how RESO does it. The backwards compatibility thing worries me here. It's a significant departure from how we do it now. This could mean this is a v3 thing. What is this doing on the

Enumeration | Description |
---|---|
ENERGY STAR Certified Homes | EPA ENERGY STAR Certified Homes is a set of optional construction practices and technologies (above minimum code requirements) that builders can follow to upgrade a new home’s energy efficiency beyond minimum code requirements. Guidelines are outlined in the “National Performance Path” or the “National Prescriptive Path.” This whole-house label differs from the ENERGY STAR products label. To achieve the ENERGY STAR Certified Homes label, a home’s energy efficiency must be verified by a third-party organization. |
Home Energy Score | The Home Energy Score, managed by the US DOE, is a national system that allows homes to receive an energy efficiency rating, similar to the MPG rating available for cars. The Home Energy Score uses a 10-point scale to reflect how much energy a home is expected to use under standard operating conditions. Homes that are expected to use the least amount of energy (and are considered the most energy efficient) score a 10, and homes that are expected to use the most amount of energy (and are considered the least energy efficient) score a 1. The Home Energy Score uses a standard calculation method and takes into account the home’s structure and envelope (walls, windows, foundation) and its heating, cooling, and hot water systems. Only Qualified Assessors who pass a DOE exam are allowed to provide the Home Energy Score. |
Home Energy Upgrade Certificate of Energy Efficiency Improvements | Buildings Performance Institute BPI- 2101 Standard Requirements for a Certificate of Completion for Whole-House Energy Efficiency Upgrades specifies a standard way of describing the improvements made to an existing home through a home energy upgrade (HEU). Certificates are provided by a local energy efficiency program sponsor. |
Home Energy Upgrade Certificate of Energy Efficiency Performance | Buildings Performance Institute BPI- 2101 Standard Requirements for a Certificate of Completion for Whole-House Energy Efficiency Upgrades specifies a standard way of describing the improvements made to an existing home through a home energy upgrade (HEU) and provides one or more measures of a home’s performance. Measures of performance may include a HERS rating, a Home Energy Score, an indication of projected or actual energy consumption, or other systems. Certificates are provided by a local energy efficiency program sponsor. |
Living Building Challenge | Living Future Institute's Homes certified by a third-party that they produce as much or more energy than they use. Super-insulated homes that have met certification requirements demonstrating minimal or no heating and cooling system. |
Certified Passive House | Super-insulated new homes that have been built to meet certification requirements demonstrating minimal or no heating and cooling system. |
HERS Index Score | The HERS Index is the nationally recognized scoring system for measuring a home’s energy performance. To calculate a home’s HERS Index Score, a certified RESNET home energy rater will do a home energy rating and compare the data against a reference home (a design-modeled home of the same size and shape as the actual home), so the HERS Index Score is always relative to the size, shape, and type of the house. The lower the number, the more energy efficient the home. |
WaterSense | EPA WaterSense is a set of optional construction practices and technologies (above minimum code requirements) that builders can follow to ensure a home uses less water while still providing the same level of comfort and convenience. WaterSense also applies to specific plumbing fixtures (see InteriorFeatures) and should not be confused with the whole-house label. |
LEED For Homes | "USGBC’s residential rating system, LEED for Homes, was launched in 2008. The LEED rating systems are developed through an open, consensus-based process led by LEED committees. LEED is a voluntary program that provides independent, third-party verification that a home was designed and built using methods for achieving high performance in multiple areas of sustainability including energy, water, waste management, indoor air quality, and sustainable site development. There are multiple rating systems for all types of buildings including Existing Buildings and Homes for residential projects. Homes may achieve different levels of certification (platinum, gold, silver, certified) depending on the number of LEED prerequisites and credits that are met." |
NGBS Whole-Home Remodel | Home Innovation Research Labs provides project certification to the NGBS. NGBS applies to both single-family homes and multifamily buildings. Certification options also exist for new construction, remodel projects (both whole-home and functional areas such as a kitchen or bathroom), and land development/subdivision. Homes may qualify for a bronze, silver, gold, or emerald certification level depending on the number of green building practices met. |
PHIUS+ | Super-insulated homes that have met certification requirements demonstrating minimal or no heating and cooling system. |
Home Performance with ENERGY STAR | Home Performance with ENERGY STAR offers whole-house solutions to high energy bills and homes with comfort problems. The program is managed by a local sponsor that recruits home improvement contractors who are qualified to perform comprehensive home assessments and improvements. Local sponsors must follow specific guidelines to participate as outlined in the HPwES Sponsor Guide and Reference Manual. |
NGBS New Construction | Home Innovation Research Labs certifies homes to the ICC-700 National Green Building Standard™ (NGBS), which has undergone the full consensus process and received approval from the American National Standards Institute (ANSI). Home Innovation Research Labs provides project certification to the NGBS. NGBS applies to both single-family homes and multifamily buildings. Certification options also exist for new construction, remodel projects (both whole-home and functional areas such as a kitchen or bathroom) and land development/subdivision. Homes may qualify for a bronze, silver, gold, or emerald certification level depending on the number of green building practices met. |
NGBS Small Projects Remodel | Home Innovation Research Labs provides project certification to the NGBS. NGBS applies to both single-family homes and multifamily buildings. Certification options also exist for new construction, remodel projects (both whole-home and functional areas such as a kitchen or bathroom), and land development/subdivision. For the Small Projects Remodel, the functional area (kitchen, bathroom, basement, addition) is either certified or not. Unlike other NGBS certifications, multiple certification levels (bronze, silver, gold, or emerald) do not exist for this certification option. |
Zero Energy Ready Home | DOE Zero Energy Ready Home is a set of optional construction practices and technologies (above minimum code and ENERGY STAR Certified Home requirements) that builders can follow to ensure high-performance homes so energy efficient all or most annual energy consumption can be offset with renewable energy. Guidelines are outlined in the "DOE Zero Energy Ready Home National Program Requirements." |
Indoor airPLUS | EPA Indoor airPLUS is a set of optional construction practices and technologies builders can follow to reduce indoor air pollutants and improve the indoor air quality in a new home beyond minimum code requirements. It is only available to homes that first meet ENERGY STAR Certified Homes certification. |
EnerPHit | Super-insulated existing homes that have been remodeled to meet certification requirements demonstrating minimal or no heating and cooling system. |
@nmerket What are the current certifications on the project node? Just HPwES? If so, would it be 'breaking the spirit' to add the whole building certifications to the building node with the three fields, but keep project certifications on the project node? Or would this be ultimately more confusing? |
@RebHudson What's currently there is HPwES, LEED Certified/Silver/Gold/Platinum, and other. Are the LEED ones more building or project certifications? |
@nmerket LEED is building level so that is an issue. |
Okay, the issue here is that we really have two kinds of certifications: ones that apply to the house itself and ones that apply to the project (measures performed). I think there should be two elements: the one as it is on the Project/ProjectDetails/ProgramCertificate
Somewhere on the Building
Each could be broken down into certification, level, and status fields as @brandongallagher suggested. Others I don't know where they go
How bad of an idea is breaking these up like this? Any better ideas? |

@juliecaracino @nmerket I had to leave the meeting prior to this discussion. We are currently working with RESO and the local MLS to have Pearl Certification added as an enumeration option for GreenBuildingVerificationType. So if we are basing the enumerations for HPXML off of RESO options let's add Pearl Certification as well. Pearl Certification would be on the building node as a whole home certification rather than a project certification. |

Looking at this, it's odd that it exists on the
Project/ProjectDetails/ProgramCertificate
node. I would have expected this to be on theBuilding
node somewhere. Anyway, we should discuss as a group to make sure these new enumerations are okay.Fixes #43
