2.3.6






Activity 2.3.6 Residential Electrical Systems


Introduction
We often take for granted that a light will illuminate when we flip a switch or that there will be an electrical outlet in a convenient location when we want to use a hair dryer. The fact that you do not notice the design of the lighting and electrical system when you are in a building indicates that the designer has done a good job anticipating the needs of the occupants. The electrical system must be designed and constructed according to the applicable building codes and regulations, but it should also be designed with the end user in mind.

In this activity you will research lighting and electrical design topics and review residential electrical code requirements. Using the knowledge you gain, you will layout the electrical system for your Affordable Housing Project.

Equipment
Computer with Internet access
Print of your Affordable Housing Project floor plan(s)
Common Electrical Symbols handout
Residential Electrical Code Requirements

Procedure
Visit the following websites:
U. S. Department of Energy Efficiency & Renewable Energy website at http://www.energysavers.gov/your_home/lighting_daylighting/index.cfm/mytopic=11970.
Whole Building Design Guide at http://www.wbdg.org/resources/daylighting.php
Review the information on lighting and daylighting and complete the following questions.
Describe the three general classifications of lighting uses.
Ambient lighting- background lighting
Task lighting-specific lighting
Acsent lighting

  • What is daylighting?
Daylighting is the ability to maximize the use of natural daylight in your home to further reduce the need for artificial lighting. Using windows and skylights in your home is a way to reduce artificial lighting.

What are some advantages to providing daylighting?
You can reduce the cost of always running lights. You also save energy.

Describe the best orientation for windows in a building in order to take advantage of daylighting.
Depending on where you live the sun shines the most in one direction. If you are above the equater then having your windows and skylights facing south is the best way.


Review your affordable home floor plans. Consider how you can better incorporate daylighting into your design. Mark at least one change on the floor plan(s) that will improve the energy efficiency of the home by increasing the daylighting. Make the change on your 3D model.
Locate an electric meter (typically mounted on an exterior wall) and sketch your proposed location for the main panel on the print of your affordable home floor plan. Choose an accessible interior location for the panel that is hidden from public view – perhaps a closet or separate space. Include the electric meter and main panel in your 3D model.
Sketch a preliminary electrical plan on your affordable home floor plan(s).
Sketch the location of outlets, lighting, and switches so as to comply with the Residential Electrical Code Requirements. Think about how each room will be used, what appliances and equipment are needed, and where extra convenience outlets should be placed.
Connect each lighting fixture to at least one switch (or as required by the Residential Electrical Code Requirements) using a switch leg (dashed line). Consider the need for three way switches.
Locate exterior outlets and lights as required by code.
Comply with all New Construction Guidelines for Habitat for Humanity.

Include an electrical service line on your electronic site plan.
(Optional) Revise your Affordable Home Project drawings to include your electrical design. You must determine the best place to show your electrical plan. Sometimes it is easiest to place it directly on a floor plan; other times you will need to prepare a separate electrical plan.
Conclusion
  1. How did you incorporate daylighting into your project?
I have many windows that will reduce the cost and save energy.



  1. Why are some electrical plans placed on a floor plan and others on a separate sheet?
If there is too much on one sheet then it will look like there is to much going on and the customer might get confused.
What is important for an architect to know about electrical plans?

So he/she doesnt build the building that will counter act with the electrical plans and so he/she builds it to the needs of the customer.



How does the design of the structure affect the electrical layout?

You cant always build it completely the way you want. there is codes and regulations that will cause problems in the future.
