CEM Floor Plan Development 5

Question 1

An energy manager is evaluating floor plans for a retrofit project. What does 'as-built' documentation mean in this context?

Accepted Answer

Floor plans reflecting actual constructed conditions, including all field changes from design drawings

Answer

As-built drawings document the building as it was actually constructed, capturing field modifications that may differ significantly from original design documents.

Question 2

A floor plan shows that a school building has classrooms on the south facade and a gymnasium on the north end. How does this layout affect energy management strategy?

Accepted Answer

Classrooms benefit from passive solar daylighting while the gymnasium requires separate high-ventilation HVAC zoning

Answer

South classrooms benefit from daylighting and passive solar, while gymnasiums have unique high-occupancy, high-ventilation needs requiring separate zone control.

Question 3

In energy auditing, what is the purpose of calculating 'energy use intensity' (EUI) normalized by floor plan area?

Accepted Answer

To enable benchmarking of energy performance across buildings of different sizes

Answer

EUI (kBtu/ft²/year) normalizes total energy use by floor area, allowing fair comparison of buildings with different sizes against each other or against benchmarks.

Question 4

A floor plan shows that a warehouse has a large overhead dock door on the east wall that remains open for extended periods during operations. What is the primary energy implication?

Accepted Answer

Massive infiltration of unconditioned outdoor air raising heating and cooling loads significantly

Answer

Large open dock doors create uncontrolled infiltration of outdoor air, dramatically increasing heating or cooling loads depending on the season.

Question 5

When developing a floor plan for energy code compliance under ASHRAE 90.1, what is the primary purpose of identifying 'semi-heated spaces'?

Accepted Answer

To apply less stringent envelope and lighting requirements than fully conditioned spaces

Answer

ASHRAE 90.1 defines semi-heated spaces as those with heating above 15 BTU/hr·ft² but not cooled, applying relaxed envelope and possibly lighting requirements compared to conditioned spaces.
