Overwhelmed by all the parts and pieces of green building? We completely understand and are here to help you! We are here to assist you with all of the steps in the green building process, regardless of whether you are renovating or adding on to an existing home, designing a new home, or certifying the construction of a new home. Read on to learn more about how we can help you with every process along the way - from initial design all the way through to the completion of your renovation or new home!

Section A - Existing Homes

Home Energy Audits are available to owners of existing homes who are concerned about the energy performance of their home and would like an independent analysis of their options. The process is specifically targeted toward energy performance, but since houses operate as a complex and highly integrated system, many homeowners also obtain insights and feedback that improve comfort, indoor air quality, and combustion safety. There are three levels of audits that can be performed:

A level 1 audit typically includes walkthrough and visual inspection of key existing conditions. At the completion of the audit the homeowner will be given a menu of possible improvements and recommendations. A level 2 audit typically includes a Level 1 Audit plus diagnostic testing using a blower door and duct blaster to measure airtightness of the ductwork and building envelope. This can be useful for the do-it-yourselfer or for homeowners who would like to have diagnostics performed prior to scheduling air sealing work. Documentation given to the homeowner will also include the test results with a short guide on how to interpret them. A level 3 audit typically includes walkthrough and visual inspection of existing conditions, including measurements of existing building surfaces, and computer energy modeling. The homeowner will receive recommendations and a menu of possible improvements, as well as a Home Energy Rating Certificate for the home, with estimated energy usage and carbon emissions. The documentation for this level of audit can include cost payback analysis for improvements and information necessary for energy efficient mortgage programs.

Thermography: Thermal imaging can be added to any of the above packages for an additional fee. Thermal imaging can be useful to visually identify defects in insulation performance, other building components that contribute to heat loss, and can sometimes show routes of moisture entry and help diagnose the extent of moisture problems. Thermography is most effective when there is a 20 degree temperature difference between indoors and outdoors, so we will try to schedule that with you at a time when that can be achieved. The thermography package includes a report that contains your photos and a brief description of what is being shown in each. Once we have identified the issues in your house and how to fix them, we promise not to leave you high and dry to figure out who to hire to fix them! We have a large network of qualified professionals we work with who can assist you with any energy-related improvement projects you may want to tackle after having an energy audit done. As a third-party consultant, we have no issues with making multiple recommendations so that you can get competitive prices, allowing you to get the most for your money. We do understand that each house is unique and different combinations of tests and inspections may be necessary to identify specific problems – we are more than happy to tailor our approach to your needs and/or budget.

Section B - The Energy Star Homes Program

The ENERGY STAR Homes program allows builders to provide a "miles per gallon" sticker for their homes (also known as a HERS rating), and is an important way that builders can demonstrate that they are building quality homes. More information is available at the Energy Star for New Homes website.

Section C - The HealthyBuilt Homes Program

HealthyBuilt Homes (HBH) is a statewide program in North Carolina that provides a certificate for builders who meet "green home" guidelines. These guidelines emphasize comfort, health, energy and water conservation, site preservation, and renewable energy use. This certification includes ENERGY STAR certification plus inspection of additional items specific to the HealthyBuilt Homes program. More information is available at the NC HealthyBuilt Homes website and the Western NC Green Building Council website.

We are trained and certified to provide the third-party, independent inspections and verifications required for ENERGY STAR and HealthyBuilt Homes, which include (but are not limited to): design review, modeling using REMRate software,thermal bypass/framing inspection, insulation inspection, testing for leakage in the HVAC duct system, testing for airtightness of the building envelope, and various site inspections for the HealthyBuilt Home checklist.

Section D - LEED for Homes

LEED for Homes is a rating system that promotes the design and construction of high-performance green homes. A green home uses less energy, water and natural resources; creates less waste; and is healthier and more comfortable for the occupants. LEED for Homes is designed to provide national consistency in defining the features of a green home and represents a consensus standard for green home building developed and refined by a diverse group of national experts and experienced green builders. Due to the intensive nature of the LEED For Homes certification process, it may or may not be the ideal certification for a particular new home. It is intended to be the "gold standard" of green certifications, and because of this, can be more expensive than other certifications like EnergyStar and HealthyBuilt Home. Please let us know if you are interested in the LEED for Homes certification process - we can answer any questions you may have! More information is available at the USGBC LEED For Homes website.

Section E - NAHB Green Certification

VandeMusser Design is trained and certified as an NAHB Green Verifier. The National Association of Home Builders (NAHB) has come up with their own green certification. There are three green home certification levels available in the NAHB Model Green Home Building Guidelines – Bronze, Silver, and Gold. (An additional Emerald level will be available in the National Green Building Standard.) The green levels and certifications address seven key green construction areas: Site, Resource Efficiency, Energy Efficiency, Water Efficiency, Indoor Environmental Quality, Homeowner Education, Global Impact. It also includes an online scoring tool and a wealth of educational tools and resources for home builders and home buyers. Like LEED For Homes, the NAHB Green certification is a nation-wide program that allows builders from all across the country to be judged by a national green standard. More information is available at the NAHB Green Certification website.

Section F - Modular Housing Plant Certification

As third-party modular plant certifiers, VandeMusser Design can assist modular housing manufacturers in certifying their facilities as ENERGY STAR-compliant plants. The ENERGY STAR Modular Home Qualifying Program is designed to take advantage of and leverage the quality control and building methods already used in modular construction. Highlights of the program include:

  • One-Time Plant Certification. Instead of requiring a third-party inspection of each home (required of site builders), the modular plant completes a one-time, ENERGY STAR certification. The factory is then responsible for maintaining quality and conformance to ENERGY STAR requirements using the factory's existing in-plant quality assurance procedures. Auditing is then done by the plant certifier twice a year to verify that the certification procedures are being upheld.
  • Energy Star "Quality-Assured" Plant Label.The plant then applies a Quality Assured label to the ENERGY STAR homes they build. This label, furnished by MHRA, indicates to the builder that the home is ready to be completed as an ENERGY STAR home. The factory provides the builder with a list of those ENERGY STAR items that must be completed at the site.
  • On-Site Completion of Home by Builder. Completion of the ENERGY STAR home is the builder's responsibility. The builder completes the items indicated on the list provided by the factory. Conformance with the ENERGY STAR requirements in the field is verified by a third party rater.
  • Second Energy Star Label after Home Completion. At the completion of construction and verification of the ENERGY STAR features, the rater provides the builder with a second label, a blue ENERGY STAR label, available from MHRA. The two labels signify that the home qualifies under the national ENERGY STAR program. More information is available at the MHRA Modular Protocol Website.

Section G - Design Consultations

We have extensive experience and expertise in building energy analysis and building envelope design, and can assist during the design phase to help make a house as efficient as possible. We can work with homeowners, architects, or builders to assist in making design decisions including: insulation type / strategies, building materials, heating / cooling strategies, or passive solar performance.

Manual J / D Calculations: While often done in-house by your HVAC contractor, we are also able to provide heating and cooling calculations using "Manual J" software. A Manual J analysis ensures properly sized cooling equipment, which provides better moisture control. A Manual D computer analysis ensures properly sized ductwork on a room-by-room basis, providing improved thermal comfort and airflow. This goes hand-in-hand with the Manual J analysis to ensure that a properly-sized mechanical system is specified for your house.

Courteous and Professional Service. We do our best to work within your construction schedule and to give you the information that you need to get the job done. We’re here to be a resource for you and your clients.

Audits For Existing Homes - What is involved? Which type of audit is right for my house?
While we try and provide some customization in putting together an energy audit for a homeowner, we have tried to outline three levels of audits so that people can budget appropriately:

  • A level 1 audit typically includes walkthrough and visual inspection of key existing conditions. At the completion of the audit, the homeowner will be given a menu of possible improvements and recommendations. We often recommend this is as the place to start. Often, the problems you are experiencing can be visually identified without any diagnostic work being done.
  • A level 2 audit typically includes a Level 1 Audit plus diagnostic testing using a blower door and duct blaster to measure airtightness of the ductwork and building envelope. This can be useful for the do-it-yourselfer or for homeowners who would like to have diagnostics performed prior to scheduling air sealing work. Documentation given to the homeowner will also include the test results with a short guide on how to interpret them.
  • A level 3 audit typically includes walkthrough and visual inspection of existing conditions, including measurements of existing building surfaces, and computer energy modeling. The homeowner will receive recommendations and a menu of possible improvements, as well as a Home Energy Rating Certificate for the home, with estimated energy usage and carbon emissions. The documentation for this level of audit can include cost payback analysis for improvements and information necessary for energy efficient mortgage programs.
  • Thermography: Thermal imaging can be added to any of the above packages for an additional fee. Thermal imaging can be useful to visually identify defects in insulation performance, other building components that contribute to heat loss, and can sometimes show routes of moisture entry and help diagnose the extent of moisture problems. The thermography package includes a report that contains your photos and a brief description of what is being shown in each.

We do understand that each house is unique and different combinations of tests and inspections may be necessary to identify specific problems – we are more than happy to tailor our approach to your needs and/or budget.

Once you have identified the problems, am I left to figure out how to fix these things on my own?
Absolutely not! We have a large network of qualified professionals we work with who can assist you with any energy-related improvement projects you may want to tackle after having an energy audit done. As a third-party consultant, we have no issues with making multiple recommendations so that you can get competetive prices, getting the most for your money.

Certifications for New Homes - What does ENERGY STAR home certification involve?
ENERGY STAR is the building block on which many other green certifications are built. Through energy modeling and on-site inspections, ENERGY STAR homes include a variety of energy- efficient features that contribute to improved home quality and homeowner comfort, and to lower energy demand and reduced air pollution, such as effective insulation, high-performance windows, tight construction and ducts, efficient heating and cooling equipment, efficient appliances, lighting, and water heater, and third-party verification.

How is ENERGY STAR different than HealthyBuilt Homes? Should I do them both?
While Energy Star is primarily focused on the energy usage of the house, the NC HealthyBuilt Homes (HBH) Program encompasses all aspects of environmental design and construction, which also includes: Site and Landscape (using erosion control / saving existing trees), Water Efficiency (high efficiency irrigation / plumbing fixtures), Indoor Air Quality (non-toxic finishes / supplemental ventilation), Materials (using durable, local, and recycled content materials). ENERGY STAR and NC HealthyBuilt Homes are an unbelievably cost-effective combination of green certifications that looks at all aspects of creating an energy-effecient and healthy home to live in.

What do the results of the energy model mean?
Once we put the house into the energy model, it will generate something called a HERS Index. The HERS Index is a scoring system in which a home built to the specifications of the HERS Reference Home (based on the 2006 IEC) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home's HERS Index, the more energy efficient it is in comparison to the HERS Reference Home. Each 1-point decrease in the HERS Index corresponds to a 1 percent reduction in energy consumption compared to the HERS Reference Home. Thus, a home with a HERS Index of 85 (the maximum Index score allowed for ENERGY STAR certification in this region) is 15 percent more energy efficient than the HERS Reference Home.

Will these certifications add to the cost of building my house?
The answer is highly dependent on how green you would like your home to be. We work with a number of builders who are routinely meeting the requirements for ENERGY STAR and HealthyBuilt Homes certification without spending any more for the actual materials used to build the houses than they normally would have - much of the energy efficiency is coming from improved construction techniques. The only tangible additional cost is for the third-party certifications themselves. That being said, the better you want your house to perform energy-wise (i.e., the lower your HERS Index), the more it can cost to get the house to perform at that level of efficiency. This is often achieved by adding renewable energy technologies, increasing insulation values, increasing HVAC and water heating efficiency, and improving the thermal efficiencies of windows.

Will it pay itself back in energy savings?
That's where our expertise comes in! Using the energy model, we have the opportunity to look at multiple energy usage scenarios by applying different kinds of materials, equipment, and appliances to see what combination gives you the best bang for your buck. We understand that a new home is a major investment - the money you put into it needs to be money well spent. We can help make recommendations on which green technologies and construction techniques make the most sense to implement.
