Let’s stay in the kitchen for today!

This week we have talked about our kitchen and we mentioned:

  • Induction Cooking – very energy efficient!
  • Convection ovens – also very energy efficient!
  • Microwave Ovens – fast and efficient
  • Impingement Ovens – mostly commercial

Let’s stay in the kitchen one more day and look at how much Hot Water is used.  Throughout your home the kitchen, bathroom, and laundry are probably the biggest users of Hot Water.

The heel of your roof truss is very important

We could quickly plunge right into a conversation and discussion about insulating on top of the exterior wall and how that impacts the heel of your roof.  That would be a great idea except I am betting that many folks aren’t quite sure what the “Heel” really is.

Roof systems are built from several component parts:

Basement Insulation

Obviously, every home has a foundation and every new home has a requirement that the foundation / basement be insulated.  With that in mind, today let’s look at what should be done and what is just plain stupid!

REQUIRED -  the Vermont Energy Code says that every new foundation must be insulated:

More about The Vermont Energy Code

We are wandering around The Vermont Energy Code and sharing with you some of the salient points but strongly suggest that you make yourself aware of what exactly is in our state’s Energy Code so that you will be an educated home owner, or home buyer, or home builder. The Energy Code is a good tool for you to use.

Here are a few random highlights:

Windows are such a pane

This entire week we have been talking about technological advances in building science and today let’s look at the pane.  That’s a pane of glass, not the other pain.

The Weak Link in your home’s Building Envelope are your windows.  Regardless of how well you install windows or how well built the windows are; the glass that you and I enjoy so much are the one area of the house that loses more heat than any other.

What is a Thermal Bridge?

A Thermal Bridge is a part of your home that transmits heat from inside to the outside.  Or, the Thermal Bridge is a good source of Heat Loss.

Remember, we are trying to reduce Heat Loss to an absolute minimum.  Insulation offers Resistance (R-Value) to the transmission of heat.  Heat moves through insulation very slowly whereas Heat moves quickly across a Thermal Bridge. 

Thermal Bridges contribute to a lot of things:

Technological advances

Yesterday we mentioned how the United States is the world’s leader in developing Solid State lighting and how all the advances in lighting have become main-stream practice so quickly.  LED bulbs are everywhere and the DOE’s estimate is that in the next twenty years Solid State Lighting will reduce lighting energy requirements by 75%.  That’s impressive.

Another area where technology is making rapid gains and improvements is in the areas of Heating and Cooling.

Solid-State Lighting

Last week we talked about the finances surrounding the purchase/building of a new home.  This week we will focus on various energy saving components that in residential construction are rapidly becoming main stream.

The United States is the world leader in developing Solid State Lighting (SSL).  Most of us know Solid State Lighting as LED’s.
