BSC Ltd. has experience working with not only new
construction but also existing small commercial and
residential buildings.  A high performance building in
that context is one that exceeds the original design
codes and standards.  Surprising success can be
achieved in operating older buildings with greater
efficiency.  A high performance audit of the property
will point to opportunities for investments in high
performance features.  

Understanding the physical behavior of the building as a
system and how this impacts energy efficiency,
durability, comfort and indoor air quality is essential to
innovating high-performance buildings.  We work with
models of the building as a system, and apply proven
techniques to resolve design problems
.
This approach requires that we consider the interactions between the primary
elements comprising the system:

  • Building envelope system; walls, floor,ceiling, insulation,windows, doors
  • Occupant behavior
  • Comfort equipment; HVAC
  • Landscape; neighboring trees, buildings, topography, and
  • Weather, climate and wind zones

Harmonizing these elements is the key to advanced enclosure technology and high-
performance buildings.  Inadequate building performance often times results in
litigation, and applying building science analysis is an effective preventive measure
against failures and defects. It is also a useful when assessing the condition of
existing buildings for restoration and retrofit.

Some of the fundamentals of indoor air quality are cut and dried.  They include
providing sufficient ventilation.   There is a national standard for that -- ASHRAE
Standard 62.2 for low rise and residential buildings. These requirements are
widely included in building codes. Complaint resolution is a different story and still
relates in equal parts to science and practical experience. When illness comes into
play, another level of diligence immediately becomes required.  Ventilation or
humidity control, perhaps better filtration might resolve these.  But they must be
taken seriously because they can sometimes lead to more serious causes that have
long term respiratory or neurological implications.  Mold problems can aggravate
allergies and trigger asthma.  Bacteria can cause specific illnesses, ranging from
minor infections to frightful diseases such as Tuberculosis. Keeping complaints
from turning into litigation is a great value proposition.
