Understanding Passive House Designs

What is a Passive House?

A Passive House is a building standard that is ultra-energy-efficient, allowing for minimal energy used for heating and cooling. This standard, while voluntary, aims to drastically reduce the ecological footprint of buildings. It’s not just a set of rules but a design philosophy that integrates seamlessly with architectural practices, ensuring that buildings are both eco-friendly and cost-effective.

Core Elements of Passive House Design


One of the hallmarks of passive house designs is superinsulation. This involves using high-performance materials that significantly reduce heat transfer. This means the building stays warmer in the winter and cooler in the summer without relying heavily on heating or cooling systems.


Creating an airtight building envelope is crucial in passive house construction. This minimizes the amount of warm or cool air that can escape the building, thus reducing the energy required to maintain comfortable indoor temperatures. Airtightness is achieved through careful construction and high-quality building materials.


Windows in passive houses are more than just glass panes; they are highly engineered components that play a key role in the home’s energy efficiency. Utilizing double or triple-paned windows, these are designed to offer excellent thermal insulation and to maximize natural light while minimizing unwanted heat gain or loss.


Proper ventilation is essential in tightly sealed homes to maintain high indoor air quality. Passive houses use energy recovery ventilation systems (ERVs) that precondition incoming fresh air using the energy contained in the outgoing stale air. This system ensures fresh air throughout the home without losing heat or coolness.

Solar Control

Controlling solar gain is critical in passive house design. Strategic placement and sizing of windows, along with external shading devices, allow passive houses to utilize the sun’s energy for heating when needed and minimize overheating during warmer months.

Energy Efficiency and Comfort

The combination of these core elements leads to a remarkable level of energy efficiency. Passive houses typically use up to 90% less energy for heating and cooling compared to standard buildings. This efficiency translates directly into comfort. Stable indoor temperatures and continuous fresh air, free from drafts and cold spots, make living in a passive house exceptionally comfortable.

Global Relevance

The passive house standard is globally recognized and can be applied in any climate. It has proven successful in a variety of environments, from the heat of Spain to the cold of Scandinavia, demonstrating its versatility and effectiveness in reducing building energy use worldwide.

By focusing on these core principles and design strategies, Shorten Homes ensures that every passive house they build is not only energy-efficient but also a comfortable and sustainable home for its residents. With their commitment to quality and customer satisfaction, Shorten Homes integrates these advanced building techniques to meet the unique needs and preferences of homeowners in the PA, NY, NJ area, making each passive house they construct a model of modern, sustainable living.

Planning Your Passive House

When planning your passive house, the key components to consider are site selection, orientation, and local climate. These factors are crucial for maximizing energy efficiency and comfort in your home.

Site Selection

Choosing the right site is the first step in planning your passive house. It’s important to select a location that supports the energy-saving goals of passive house designs. Here’s what you should look for:

  • South-facing sites are ideal in the Northern Hemisphere to take advantage of solar gains.
  • Avoid sites with excessive shading from trees or neighboring buildings to ensure your home can utilize natural light.
  • Consider local wind patterns and topography to protect your home from potential cold winds and to utilize natural ventilation.


The orientation of your passive house plays a pivotal role in its energy efficiency. Proper orientation can reduce heating and cooling demands significantly. Here are some tips:

  • Maximize south-facing windows to absorb heat during the winter months.
  • Limit window size on the east and west facades to reduce unwanted heat gain and glare.
  • Design overhangs or use shading devices to block summer sun while allowing winter sun to warm the house.

Local Climate

Understanding your local climate is essential for designing a passive house that performs optimally. Factors like temperature, humidity, and solar insolation should influence the design decisions:

  • Use climate data to determine insulation levels and window specifications.
  • Consider moisture control strategies to handle local humidity levels and prevent mold growth.

The Best Shape for a Passive House

Simple geometric shapes like cuboids are preferred in passive house design due to their efficiency:

  • Simple shapes (like rectangles) have a lower surface-to-volume (S/V) ratio, which minimizes heat loss.
  • Compact forms are easier to air seal and insulate effectively.

Integrating Renewable Energy Solutions

Renewable energy technologies can greatly enhance the performance of passive houses. Consider these options:

  • Solar panels: A well-designed solar PV system can generate most, if not all, of the electricity a passive house needs.
  • Heat pumps: These are effective for meeting low heating and cooling demands in a highly insulated and airtight home.
  • Energy recovery ventilators (ERVs): These systems recover heat from exhaust air and use it to warm incoming fresh air, reducing heating demands.

By carefully planning and integrating these elements, Shorten Homes ensures that each passive house design not only meets the rigorous standards of energy efficiency but also aligns with the homeowner’s vision and the characteristics of the local environment. This thoughtful approach leads seamlessly into the detailed customization and construction phases, ensuring every passive house is a beacon of sustainability and comfort.
