Technical Committee: 4.4 Building Materials and Building Envelope Performance
Passive and net-zero-energy buildings have many similarities, as both methodologies have the objective to reduce the amount of heating and cooling energy used by having energy efficient and air-tight envelopes. However, there are also important differences beyond being one is created in Europe and another in North-America. This seminar describes the role the envelope has in both methods to minimize energy use and the importance envelope has on HVAC systems.
1 Climate Specific Passive Building Challenges

Katrin Klingenberg, Passive House Institute US | PHIUS |
Passive house standard are among the highest in relationship with building envelope. Since building envelope is a key component in net zero buildings, many of the design procedure can also be applied to net zero buildings. This presentation covers the fundamentals and climate considerations with designing passive construction.
2 Building Energy and Envelope Performance of a Near Net Zero Energy Building

Stanley Gatland II, Certainteed |
Pennsylvania State University’s GridSTAR Experience Center, located at the Philadelphia Navy Yard, features a near net zero energy building. A unique combination of building materials, construction methods, energy management strategies and renewable energy sources were employed to approach net zero. Research was conducted to evaluate building energy and envelope performance. The results of the measured building energy performance were compared to whole-building energy simulations and one-dimensional hygrothermal modeling. This presentation covers important envelope considerations and lessons learned to achieve near net zero energy residential buildings.
3 Hygrothermal Considerations for Building Envelopes in Passive Buildings

Florian Antretter, Fraunhofer-Institut für Bauphysik |
Net zero and passive buildings are intrinsically air tight. This can present challenges if the envelope and HVAC systems are not correctly designed. This presentation covers hygrothermal fundamentals as well as design and modeling considerations for building envelopes in passive and high efficiency buildings.
