LP Smartside siding

We will be utilizing LP Smartside siding products on an up-coming project and are looking forward to comparing for ourselves how this highly rated product stacks up to the Hardi fiber cement siding products that we have installed on so many projects over the years.
We will be installing a mix of clapboard siding as well as board and baton siding on this project. The clapboard siding is available in wood grain and smooth textures and can be ordered pre-finished which we will do. The board and baton will be accomplished by installing 4'x8' LP panels and attaching batons on a 16"oc layout which will cover the panel seams.
These products are highly sustainable and have a great warranty, two things that we are always looking for when selecting building products.
I will report back as the install takes place with further thoughts as we are working with the actual products.

Mini Split Heat Pump HVAC

We have utilized mini split heat pump HVAC systems in a number of our projects over the past several years. Most of these have been Mitsubishi systems and have been installed by our excellent trade partner Royal River Heat Pumps in Freeport ME.

Customer feedback indicates that these systems are extremely quiet, cost efficient to operate, and provide reliable heating throughout our cold Maine winter weather.
Of course they also provide warm weather air conditioning which more and more of our clients have been including in their "must have" list when designing their new homes.
The cost of these systems is much less than adding air conditioning to an LP or Fuel oil heated home project, and the efficiency is far better (cost to operate is much lower).

These systems are available as ducted systems with no exposed equipment, wall hung units, and floor units all of which have been utilized in our projects.

Mini spit heat pump HVAC should be a consideration for your new home project.

Boral Siding and Trim

We have recently completed a project where Boral siding and trim products were utilized.
Boral is manufactured with 70% recycled materials, is extremely moisture resistant, and is dimensionally stable during temperature and humidity changes (unlike wood and other non wood siding and trim products).
It looks great installed and is indistinguishable from wood siding and trim once painted.
We are looking forward to using this sustainable product again soon on future projects.

Blower Door Testing up-date #3

I have previously made blog entries regarding blower door shell testing on new home construction to locate and address air leaks within the building envelope of conditioned space. These tests are conducted by an independent energy auditor once a new home is tight to weather and (typically) after it has been insulated.
Recently we conducted such a test on a new project which was constructed and insulated similarly to other projects that we have tested.
The test resulted in 0.85 ACH/50. Pretty good numbers!
Other similar homes tested somewhat higher and as I think about differences between these projects the one item that I can identify that could be the reason for an improvement is that on this recent test every window in the house is either a casement window or a fixed window where as the other homes we have tested had a mix of casement, awning, and double hung windows (the window manufacturer (Andersen) and model (A-Series) were the same in all of our test homes).
Some of our homeowner clients have voiced their preference for not having any casement windows in their new homes but for those that are not opposed the casement window style does have an energy performance advantage when a house is under negative pressure (windy weather).

LED lighting and new home construction

LED lighting is helping to make our new home building projects more energy efficient than ever before. As LED lighting options have become more abundant and affordable it is being utilized almost exclusively throughout our new home building projects in a variety of applications.
Whether selecting LED bulbs for lighting fixtures, LED bulb/trim inserts for recessed lighting, or LED "ribbon" accent lighting for under cabinet and display applications, whole house LED lighting can make a significant impact on energy costs.
In my own all LED house, one string of incandescent Christmas tree lights consumed more electricity that the remainder of the house lighting combined (we will have LED Christmas lights this year)!

A cure for thermal bridging

We have utilized a number of strategies to combat thermal bridging, the heat loss/transfer that occurs through the connection between conditioned and un-conditioned space by framing lumber.
A relatively new product that we have recently utilized is the ZIP R-Sheathing from Huber Wood the maker of Advantech floor/wall/roof sheathing.
ZIP R-Sheathing combines the popular ZIP System sheathing and continuous foam insulation available in 1" which includes 1/2" R-3.3 foam, and 1-1/2" which includes 1" R-6.6 foam.
Some advantages of the ZIP R-Sheathing is a one step installation of wall sheathing and foam envelope insulation, tight to weather walls as soon as the proprietary "ZIP" tape has been installed on the seams, and a reasonable balance of cost to build and energy efficiency.
We will definitely use the ZIP R-Sheathing again on upcoming projects and recommend it as a consideration for your future new home construction project.

 

 

 

 

Another new product that we have recently utilized for the fist time is "ZIP system Liquid Flash". Liquid flash as the name implies is a liquid flashing material for sealing sheathing seams and preparing window and door openings. It is applied with a caulk gun and plastic spreader. The applied product is very tough and durable and looks to be an improvement to some previously widely used weather management techniques. Wear rubber gloves when applying liquid flash!
