BPI MFBA 2024 Exam Correct
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
, Passed!!
2024/2025
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
, Passed!!

An example of the Whole Building Approach would be:
Painting the roof silver to lower the cooling load of the building
Conduction is a major concern in these parts of a building EXCEPT:
Interior walls
Air moves from:
High pressure to low pressure
Snow melting on a roof probably indicates what potential issue with a building
Conduction because of a poorly insulate roof
Which of the following affects air, heat & moisture movement?
- Temperature/Pressure difference,
- Material,
- Distance.
Delta T (∆T) describes a difference in ____________
Temperature
Open pipe penetrations through the ceiling of a parking garage are a break in
the building's:
- Moisture barrier
- Thermal barrier
- Pressure barrier
Open windows in a apartment building create a break in the building's:
Thermal barrier
A water pump in a boiler room should be evaluated for potential:
- Electrical inefficiencies
- Signs of bulk moisture
- Vibration and noise
, Passed!!

A seam or opening between building components is a concern because heat loss
may be taking place by:
Convenction
A super can insulate a roof with either rigid board fiberglass with an R value of
4 per inch for $2.50 per square foot or a polyurethane spray with an R value of 7
per inch for $2.00 per square foot. Which product will insulate better:
The polyurethane spray
A building needs to replace the windows. The super proposes replacing the
original aluminum windows with vinyl windows because:
Vinyl windows have a lower U-value
An electrician installs high hat LED lights on the top floor of a small multifamily
building with a pitched roof. The super is concerned about the new fixtures
because:
The penetration in the ceiling may create a break in the thermal and pressure
boundaries
Which of the following factors affect the amount of heat loss through
conduction?
a.) U-value
b.) Surface Area
c.) Temperature Difference
A tenant on the top floor of a building complains that their apartment is always
hot. Which of the following would not help address the problem?
Improving drainage on the roof
Which of the following windows has the most heat flowing through it?
Single glazed window with a U-value of 0.90
An apartment is vacated and requires renovation. Which of the following is not
a strategy to air seal an apartment during a renovation?
