Passive and Active Solar Models

8th Grade EnrichmentFall, 2012

Samples

• Models are made of ¼ “ foam core• Models are built at a scale of ¼” = 1’• Models display passive solar design principals• Students built the models in Google SketchUp

Here are some examples :

Solar House: David Passive Solar Features of the House: 1: South Facing Windows 120 ft square in total.2: Vent on south side3: Clerestory windows4: one small skylight as a result of failed lightbulb installation. Active Solar Features: 1: Ceiling Fan2: Attempted solar lightbulb -> stolen, created small skylight Square footage of the floor of the house in total: 1000 feet square.

Passive solar features:Passive solar design integrates a combination of building features to reduce or even eliminate the need for mechanical cooling and heating and daytime artificial lighting. Designers and builders pay particular attention to the sun to minimize heating and cooling needs. Some passive solar features I used in my house were windows facing south. Over my windows I had an over hang facing the south roof and I used Clerestory windows. Active solar features: Then I used active solar features in my house. Active solar is the design of buildings that contain mechanical devices, which transport the absorbed solar energy to other locations in the building, or convert solar energy into electricity. So I used sky lights and solar panels in my house. Square footage of the floor: 514.5807 Feet ²Square footage of the south windows: 61.52 Feet ²

2. Overhang of south side roof: planed but rafters were to short

Active Solar Features (2 watts on, 1 watt used, infinite watts possible)1. Ceiling fans: possible2. Sky lights: would have to be small3. Water features: possible4. Highly effective light: yep, now if only I could change the battery

Square footage of the floor: 1000Square footage of the south windows: (5*(8*4))*3=480

This is my house in Google Sketch-up

Passive Solar Design• Uses natural movement of heat and air to maintain comfortable

temperatures

• Maximizes the benefits it receives from the sun with standard construction features.

• Takes advantage of local breezes and landscape features such as shade trees and windbreaks

• Uses a simple system to collect and store solar energy with no switches or controls.

Five Main Passive Design Principals

Orientation towards the sun

Overhangs and Shading

Insulation

Placement of windows to gain heat and minimize heat loss

Thermal Mass

Orientation towards the sun

• Use Google SketchUp • Create a simple shape• Follow these directions:
