ARCH TECH
LECTURE 9 INFO
| Question | Answer |
|---|---|
| What are building service systems responsible for? | Comfort, health, and energy performance in buildings. |
| What do building service systems control? | Thermal comfort, fresh air, water supply, sanitation, lighting, power, life safety, and fire safety |
| What does MEP stand for? | Mechanical, electrical, plumbing |
| Why must architects understand MEP systems? | Because design decision strongly influence their performance and layout. |
| What aspects of design affect building services? | Energy demand, equipment space, routing of ducts, maintanence access, integration with structure and envelope. |
| What is the result of good coordination? | Efficient, accessible and maintainable systems |
| What does HVAC stand for? | Heating, ventilation, and air conditioning |
| What conditions does HVAC maintain? | Temperature, humidity, air movement, and indoor air quality |
| What are typical HVAC components? | Heat source (boiler, heat pump), cooling source (chiller) air handling units, ducts and pipes, diffusers, and controls |
| How is heating or cooling distributed? | Airbased systems and water based systems |
| What design decisions affect HVAC performance? | Building form and orientation, insulation and airtightness, window size and placement, interior layout and ceiling space, mechanical room location. |
| What happens with poor coordination? | Larger less efficient mechanical systems |
| What happens with good design? | Reduced mechanical demand |
| How do furnaces work? | Heat air and distribute it through ducts |
| How do boilers work? | Heat water and distribute it through pipes |
| How is heat delivered from boilers? | Radiators, baseboards, or radiant floors |
| How do heat pumps work? | Move heat instead of generating it |
| What modes can heat pumps operate in? | Heating and cooling |
| What types of heat pumps exist? | Air source and ground source |
| What is an ERV? | Energy recovery ventilator |
| What does an ERV do? | Exchanges heat between incoming fresh air and outgoing exhaust air |
| Why is ventilation important? | Maintains indoor air quality and removes pollutants. |
| What factors influence system choice? | Heating/cooling needs, frost protection, fire code requirements, capital cost, and operating cost. |
| What is a key rule in plumbing layout? | Stack floors to minimize pipe runs |
| Why is this important? | Reduces cost, improves efficiency, and simplifies construction |
| What are the main components of building service systems? | Heat/cooling sources, air handling equipment, ducts or pipes, diffusers, and controls. |
| What is the most important relationship in building services? | Architecture and systems must be integrated |
| What happens if systems are considered too late? | Inefficient design, higher costs, poor performance. |
| What is the goal of good service system design? | Efficiency, comfort, and maintainability. |
