Lesson 1 Flashcards
Perform mechanical, electrical, and civil engineering work in design, construction,
operation, and maintenance of water systems, electrical power lines, and power
plants, telecommunications facilities, gas pipelines, and light and heavy rail
systems.
ENGINEERING UTILITIES
Practicing the engineering disciplines that carry sustainability concepts through
building design construction, commissioning, operation, and ultimately demolition, recycling, and reuse.
ENGINEERING UTILITIES
Involves understanding the design, construction, operations, and maintenance of machines
MECHANICAL SYSTEMS
HVAC
Heating, Ventilation, and Air Conditioning
Refrigeration and Hydronic System are part of
MECHANICAL SYSTEMS
ROLE OF UTILITY ENGINEER
● Provide decision
- Result from extensive and careful analysis
- Cost and other implications for the utility
- Other options like spend money now to save money later
● Understand the criteria for deciding which decisions are best from a business perspective.
● Engineering Solutions produce higher profit
TYPES OF UTILITIES
● Electric Utilities
● Gas Utilities
● Water Utilities
● Telephone Utilities
● Wastewater Utilities
Produce electric power and deliver this power to customers.
ELECTRIC UTILITIES
Functions of Electrical Utilities
Generation, transmission, and distribution
is generated at large central stations that use fuel such as coal, oil, natural gas, or uranium (nuclear reactors).
Electric power
Required to provide electric power to their customers at an acceptable voltage.
ELECTRIC UTILITIES
can harm electric appliances and cause potential safety hazards.
High voltages
can cause electric appliances to function improperly and can cause
electric motors to overheat.
Low voltages
Other aspects of voltage that utilities must consider are
frequency, flicker, transients & harmonics
Is the decision and practice of using less energy.
Energy Conservation
Produce natural gas and deliver it to customers.
GAS UTILITIES
Functions of Gas Utilities
Generation, Transmission, and Distribution
comes from wells that drill into underground deposits in natural gas fields.
Natural gas
Produce drinkable (portable) water and deliver it to customers.
WATER UTILITIES
Functions of Water Utilities
Treatment, Transmission, and Distribution
is naturally collected in geographic watersheds, where it drains into
river systems, lakes, and underground aquifers.
Rainwater
always addresses health related issues such as the presence of
biological and toxic contaminants.
Water treatment
Required to provide drinking water to customers with sufficient pressure and purity.
WATER UTILITIES
This is different from electricity, gas, and water. Does not generate a product and transport this product to customers.
TELEPHONE UTILITIES
Often called a sewage utility
WASTEWATER UTILITIES
it transports dirty water away from customers and treats the dirty water so that it is suitable to be discharged into the environment.
WASTEWATER UTILITIES
are natural monopolies, they require government oversight so that they do
not exercise monopoly power to the detriment of customers & society.
Utilities
establish regulations and monitor for compliance.
Regulatory bodies
Goals of regulators
to have utility services provided with adequate service
levels for the lowest possible rates
UTILITIES EQUIPMENT
● Water – Cooled Chiller
● Air Conditioning System
● Cooling Tower
● Air Compressor System
is an integral part of the larger and more complex building
procurement process through which an owner defines facility needs, considers
architectural possibilities, contracts for design and construction services and uses
the resulting facility.
Design Process
During the ______ will determine the need for specific mechanical and
electrical systems and equipment, and very often will determine eventual owner and
occupant satisfaction.
Design Process
A building project typically begins with _______ that establish the need for,
feasibility of, and proposed scope for a facility
Pre-design activities
Pre-design activities may be conducted by
Design Team by the owner, or by a specialized consultant
is simply a statement that outlines the expected high-level outcome of
the design process.
Design Intent
Strong design intent will result in the
“first, best moves”
weak intent will result in a
weak building
Design intents might include the ff:
outstanding comfort, latest in information technology, indoor environmental quality, carbon neutral, and high degree of flexibility
are the benchmarks against which success or failure in meeting design
intent is measured.
Design Criteria
sudden change for no obvious reason
Whimsical Change
ASHRAE
American Society of
Heating, Refrigerating and Air Conditioning Engineers
The power density of the lighting system will be no greater than
0.7W/𝑓𝑡2
LEED
Leadership in Energy and Environmental
Design
Fifty percent of the building water consumption will be provided by
rainwater
capture
Background sound level in classrooms will not exceed
65 dB
