BPI MFBA
Steps of Building Analysis
GENERAL:
- Comply w/BPI Code of Ethics (1.1)
- All Assumptions Documented (1.2)
PRE_SITE VISIT:
- Compile Energy & Water Data (1.7)
- Determine most important decision-makers (1.6)
SITE VISIT:
- Collect data for energy efficiency opportunities (1.13)
- Request Blueprints (1.8)
REPORT:
- Utility/Water consumption analysis (1.14)
,- Cost/Benefit Analysis
Give 3 examples of convection
a.) Hot combustion gases convecting against the inside metal surface of a
pipe
b.) Cold skin (coming from a cold classroom) against hot and humid air
(outside of the building)
c.) Magma against the inside of the volcano
Name 4 factors that determine comfort
a.) Air temperature
b.) Radiant temperature
c.) Relative humidity
d.) Air movement
,When does a thermal bypass happen?
A thermal bypass happens when heat is carried by airflow across the thermal
boundary and around insulation. This usually happens when the air barrier
and the insulation is not close together and thus, convecting air is able to
carry heat from one surface to another across air spaces easily.
Factors to consider when calculating a building’s heating and cooling loads.
a.) Air leakage and ventilation
b.) Internal heat gains
c.) Local climate
Name 3 chief causes of backdrafting and spillage in central heating systems.
a.) Blocked chimneys
b.) Cracked heat exchangers
c.) Improperly designed or installed venting
, Reasons why moisture condensation is an important issue that needs to be
addressed.
a.) Water leads to building deterioration by biological pests. These pests also
create a threat to human respiratory health.
b.) Water corrodes metal, dissolves glue, warps wood, and weakens mortar.
c.) Water reduces the thermal resistance of insulation and may permanently
damage it.
Before doing a site visit, according to BPI standards, an analyst should collect
utility data. How much (or how long) of utility data should the analyst collect?
1 year to 15 months
During a site visit, according to BPI standards, an analyst should inspect for
hidden moisture issues. What areas does BPI give priority to?
Around windows, a/c units, bathrooms and sinks
