Energy Efficiency

Various types of insulation have been used in masonry cavity walls: rigid foam boards, spray polyurethane foam (SPF) and mineral wool. Among these, two rigid foams predominate: extruded polystyrene (XPS) and polyisocyanurate (polyiso).

Builders who understand and communicate energy-efficient benefits can provide unique added value to the growing number of buyers who, whether they recognize it or not, want these features in their homes.

This project has forced our team to focus on the energy-efficient side of home building. We realized early on we could not expect to achieve Net-Zero without also paying close attention to build quality, engineering and architecture.

Making sure that your home is properly insulated is an important step to ensure that your home remains comfortable year round and avoids wasting energy. Understanding the most common signs that your property is under-insulated can determine the best steps to improve the overall energy efficiency.

Along with Pardee, other builders have focused on more energy-efficient construction, and a greener marketing message, to entice consumers.

JW Architects was founded in a garage in 2009 and then moved into two offices in a historic building in Columbia City. In 2014, we had the opportunity to design their new high-performance-energy office space.

On March 28, 2018, at 9:30 AM, California Energy Commission staff will host a one-hour webinar to share information on projects focusing on innovative energy efficient walls.

In January of 2018, Johns Manville launched The Source; the innovative online resource designed to help professionals in the mechanical, HVAC, and industrial insulation industries stay up to speed on the latest information.

SilveRboard Graphite XS  is an expanded polystyrene (EPS) base material that is embedded with carbon ‘graphite’ particles that increase the insulation’s thermal performance. The Graphite EPS beads reflect radiant heat energy similar to the effect of a mirror that reduces thermal conductivity

Regardless of what materials and combined solutions are selected for a high-performance envelope, the trend will likely continue toward the specification of less products, especially if those selected can perform more of the key barrier functions: thermal, air, water and moisture.
