ARE YOU A DEVELOPER CONSIDERING A PASSIVE MULTIFAMILY PROJECT?
Make the case to investors and incentive program managers that an investment in your project will meet modeled performance targets and program goals. Learn more on the Investors page.
Here are the most important things you need to know:
1. passive building requires integrated design practices to assure best quality and economic results.
The decision to commit to PHIUS+ 2015 Passive Building Certification will impact the planning and delivery process from the beginning. It will define how a development budget and timeline for a project are laid out, and determine who the best qualified team members are. Regular coordination meetings with all team members present are highly recommended.
Helpful hint: If unsure about the viability of a particular project candidate, consider an economic feasibility study early on in the design phase. PHIUS provides such quick feasibility studies at a low cost to affordable housing developers. The study will help you compare current code construction cost and performance in your area to passive building cost and performance. With that information in hand the developer is in a much better position to assess if the project is a good candidate or not (especially recommended for retrofits which tend to be more costly than new builds). Once the project is deemed economically feasible and the project team decides to go forward with the planning process, then the designated CPHC® (Certified Passive House Consultant) can continue with more detailed modeling of the project and guide it through the certification process through to completion.
2. building a qualified team is crucial.
An experienced team of certified passive building professionals from all relevant fields (Certified Passive House Consultant - CPHC®, PHIUS Certified Builder, PHIUS+ Certified Rater/Large Building Verifier) can help ensure that a project comes in as budgeted, on time, and with full quality assurance. Look for professionals who have worked with PHIUS on similarly sized projects before and are knowledgeable regarding the certification and quality assurance process for multifamily buildings [link to professionals database and projects].
3. PHIUS has a uniquely designed quality assurance process.
It is the only passive building certification program in the US that third party verifies the design process as well as onsite implementation of a project. PHIUS certification staff has reviewed close to 1000 projects nationwide total in all North American climate zones with the exception of zone 2 (southern Florida). All PHIUS professionals are trained in passive technologies and familiar with when to engage in the certification process to make it go as smoothly as possible. PHIUS’s experienced certification staff provides valuable assistance and additional consulting to the consultant throughout the entire process to assure quality for the client and to minimize any risk factors.
4. passive buildings are built with commonly available construction materials.
All materials necessary to execute passive buildings are affordably available in the US and Canada. Some believe that expensive imports and specialty products are needed to complete passive houses and buildings - this is not true. However, it is advisable to verify product performance data to assure accurate energy model assumptions for the materials used. A good source for such third party verification of suitable products, components and performance data for the modeling process are the manufacturers directly and the PHIUS website where already evaluated and verified products are listed [link].
5. commit to achieving full certification!
The PHIUS+ certification program and multifamily onsite verification protocols have been specifically designed for the North American construction market to assure thorough third party verification throughout design and implementation based on accepted industry standards and building science practices. The program is aligned with and promoted by the Department of Energy Zero Energy Home Program. Achieving PHIUS+ certification is the best way to assure built performance and minimize risks.
