surprise Quiz

Question 1

(22) Active Systems:
What Is an Active System?

Answer 1

Uses equipment:
- Mechanical (M)
- Electrical (E)
- Plumbing (P)

o. Controlled, consistent comfort
o. Includes HVAC, lighting, water systems.
o. (HVAC = Heating, Ventilation and Air Conditioning)

Question 2

Active Mechanical Systems

Answer 2

Heating: furnaces, boilers, radiant floors

Cooling: chillers, air conditioners

Ventilation: mechanical supply and return, filtration

Question 3

Active Electrical Systems

Answer 3

Lighting: task, ambient, emergency

Smart Controls: motion sensors, daylight dimmers

Power Supply: wiring, circuits, panels, solar PV

Question 4

Active Plumbing Systems

Answer 4

Water Supply: hot and cold domestic systems

Wastewater: sanitary and storm drainage

Fire Protection: sprinklers, standpipes

Question 5

(30) Hybrid systems
Best of Both:

Answer 5

Combine passive with efficient active systems

Reduce energy load with design, then use machines efficiently

***Called “integrated MEP design” – requires early collaboration

Question 6

Hybrid systems

BedZED - Beddington Zero Energy Development

Answer 6

Architect: ZEDfactory Architects in partnership with Bioregional
(Wallington, UK - 2002)

• Mixed-use sustainable community comprises 100 homes, office space, a college and community facilities.
• Passive Elements: Solar orientation, insulation, ventilation
• Active Systems: CHP plant, solar panels

Question 7

What Are We Controlling?

Answer 7

Thermal Comfort – temperature and heat flow
Air Quality – fresh air, pollutant removal
Lighting – daylight and electric light
Moisture Control – humidity, condensation, mold

Question 8

What building’s need (The Design Challenge)

Answer 8

o. Climate + Comfort + Energy

o. Buildings must balance occupant needs with environmental realities

o. Every design decision has energy implications

Question 9

What Is a Passive System?

Answer 9

• Works without mechanical equipment
• Uses natural forces: sun, wind, mass, gravity
• Built into form, materials, and orientation

Question 10

Core Passive Strategies

Answer 10

• Site Orientation (maximize winter sun, minimize summer sun)
• Shading (overhangs, louvers, vegetation)
• Daylighting (skylights, light shelves)
• Core Passive Strategies
  Natural ventilation (stack effect, cross breeze) (hot air rises!)
• Thermal mass (store and release heat in masonry)
• Insulation in envelope (resist heat flow)

Question 11

(Core Passive Strategies)
what is Thermal Mass?

Answer 11

– Holds heat for long periods. Gains it through the day and emits it at night. Cool during the day. (thermal swings)
