How to build a log House-Part 2

This article on How to build a log House-Part 2 is part of a 2 other articles on this subject of how to build a Log House from the foundation to roof in totality. On hard ground where bedrock is close to the surface, buildings usually require only a minimum foundation.

The Types of foundation generally used in a log house:

1– Pier foundation:
Its the simplest and least expensive, where concrete or flat stones are mortared or laid dry.

2– Slab Foundation:
The Slab Foundation for a home plan is, of the simple kinds of foundation where a concrete slab is used as the foundation.

3- Perimeter Foundation for a house floor :
Its made from concrete, concrete blocks, or sometimes stones. Follow the architectural Floor Plan very closely with respects to the dimensions as this will cause the finishes to look tardy, if it is not correctly followed. The ceiling lines, the tiles finishes and the wall straightness will appear tardy if the dimensions of the Log House floor plans are not strictly followed.

4- Full Basement Foundation:
This is the most complicated type of foundation, Its made of poured reinforced concrete or concrete blocks
Note: Regardless what type of foundation is chosen a proper footing is needed to be placed slightly below the frost.

How to make the foundation for a log house?

Step One: Establish the Boundaries.
1-Establish the exact outside boundaries of your home using a 2”x2” stakes, nails & a rope.
2- Make one end of each stick sharp to be able to drive it into the ground easily.
3-After placing the sticks hammer a nail into the upper center of each stake
4-Once the stakes are placed in position use a rope and connect it to the nails on top of each stake
5-Once three stakes are connected you will able to outline an approximate 90 degree between two walls.
6-Make sure that the angle between the two walls is a perfect 90 degree angle using a triangle with proportions of 3:4:5

Step Two: Erect Batter Boards:
1- The batter board is made by driving 2″x4″ stakes into the ground in an L shape around the corners
2- Nail, a 1”x4’ or 1”x6” batter board, to the stakes to create a right angle and it have to be set back at least 4 feet from the outline stakes and the height is minimum 18″
3- Make sure all batter boards have been installed on all corners at the correct height.
4- Tie weight to builder’s string and drop them over the tops of the batter boards and drop a plumb bob where the two strings cross.
5-Make sure the plumb bob falls exactly on the nail head in the corner stakes this locates the outside boundary of your foundation.
6- Use the same method to locate the inside boundary but by deducting the width of the proposed foundation.

Net Energy Building for Office Tower

Models for Net Zero Energy Buildings are used by  Net Zero Architects to calculate the amount of energy saving in the schematic stages of the design, which then are  used as a basis of energy  design control through out the design implementation stages.The model is a 3-D electronic model of a building, it is also a simplified model without much details of the building, which will help calculate the calculation intentions. It is refereed as a shoe box model. There are many types of models used in designing a Net Zero Energy Building design.There are 11 types of Energy Model, which are:

1.) Heat Transfer model for Net Zero Energy Buildings in House Floor Plans
Model show that show how the heat is transferred from the outside to the interiors of the building architectural floor plans.
2.) Lighting model for Net Zero Energy Buildings  in House Floor Plans
Model showing how the day light penetrates top the interiors of the building and it helps Architect to design the light fittings in the building architectural layout outs.
The study of a the lighting levels through out the day would show the amount of light derived from the sun into the building and it helps the Net Zero Energy Buildings Architects to design the additional lighting need ed to make the building sufficiently lighted up.
The amount of light that can be daylight harvested can also be studied, note the amount of light lux derived from the sun is about 100,000-140,000 lux in comparison to what is needed in the office space is only a merger 400lux, the potentials of day light harvesting has to be considered seriously in the light of the current worldwide needs.
3.) BIM Model-Building Information Model for Net Zero Energy Buildings  in House Floor Plans
A digital computerized model, which has information about clashes of the architectural and engineering elements, it provides information about costing, and when plug-in with time project management time line program, we are able to produce the physical model developing over the time line of the builder. The model can be used to study the thermal heat, energy model and total embodied energy of the building architectural plans. This is a great tool for architects and project management consultants.
4.) Energy Model  for Net Zero Energy Buildings  in House Floor Plans
–A simple model used for computerized computation of the energy usage in the building for every month or per year based on the climate conditions, and the building insulation and orientation for buildings. A designing tool, which is helpful to Net Zero Energy Buildings Architects in  choosing the mass proportion and selection of materials.
5.) Wind Model for Net Zero Energy Buildings  in House Floor Plans
– A simple model used for computerized computation of the direction of the wind into the building based on the openings of the buildings. It will help Net Zero Energy Buildings Architects to decide where openings shall be created to enable wind to be harvested.
6.) CFD-for Net Zero Energy Buildings  in House Floor Plans
Computerized Fluid Dynamics is a study of the flow of air in  a  building, where the direction is established and the comfort is designed and it is a tool for Net Zero Energy Buildings Architects to remove impediments to comfort. It helps the architects to design buildings of how the heated air flows, how the ventilation of air flows throughout the building.
7.) Massing and Study Model for Net Zero Energy Buildings  in House Floor Plans
-a model used by Net Zero Energy Buildings Architects to evaluate the proportion, the shape , bulk , form aesthetics and how the form affects the environment.
8.) Thermal Model for Net Zero Energy Buildings  in House Floor Plans
– a model which reveal the sides of the building, where is heated up during the day. With the Thermal model the building designer may be able to decide how the building may be treated or insulated to keep the thermal heat from entering in to the building.
9.) Solar Path Model– for Net Zero Energy Buildings  in House Floor Plans
The path of the sun through out the year, and how it affects the building’s shadow and how it affects the sun’s rays into the window openings and show how the sun’s ray falls on the building and the building’s shadows is cast and how the neighboring building’s shadow affect the building that is being designed.
10.) Ventilation Model– for Net Zero Energy Buildings  in House Floor Plans
The study of wind and movement of air within the building
