Passive-Solar-Design Simplified:

The Springtime Cottage

We first recommend hiring the right professional architect. Seek designers with passive-solar-design and energy-efficient building envelope experience. We prefer collaboration with clients and designers for custom solutions. For those with simple needs and small space requirements, our Springtime Cottage and consulting services are a good fit for many projects.

Minimize the size and footprint of a 3BR 2BA, ADA accessible, master-on-main plan and its tough to beat our passive solar design plans for space, efficiency and universal appeal. The hidden beauty is a simplistic starting point. It's easy to adapt for different building-site orientations, a difficult task for most passive-solar-designs, and their alignment with the southern sky.

Use the small floorplan as a beginning, customize space for interior needs and add outdoor connections for site conditions. The plan set includes window specifications critical to passive-solar performance; SHGC values, airtight installation details and overhang sizing based on latitude for proper summer shading.

Most important are the connection details that come with the plan; foundation to wall, wall to window, and wall to roof/attic. These weakest thermal connections are addressed in detail, designed to excel in blower door tests and have more continuous insulation to reduce thermal bridging. Passive-solar-design, most importantly, relies on a good building envelope.
