My Latest Home Energy Makeover

I wanted to take you inside my most recent home energy makeover.  It is a 2,454 sf, one story home built in the 70's. 
The Volume is 19,930 cf

 The duct work was metal and leaky.  The insulation was compacted and dirty.  There were several open chases, open walls, penetrations, wall returns and thermal by-passes 

 The furnace was old, open combustion and 78% efficient

There were two inefficient, atmospherically vented, 50 gallon hot water heaters

   

A lot of planning goes into one of these.  Here are my field sketches,

3-D drawings, load calculations, zoning schematic and duct layout. 





The homeowner decided on a non-vented attic with spray-foam and

sealed combustion furnace.  we hauled away the two inefficient

hot water heaters and gave her back two "new" closets.  We installed

one tankless hot water heater with a comfort recirculating system.

The new tankless is extrememly efficient, has unlimited hot water, is instant and can be shut off with one small button.  It is laso very safe because it is sealed combustion.  It uses a concentic kit just like the furnace.  Fresh air in through the roof through a pvc pipe, and flue gases out through another

The Air conditioning system used was a Carrier performance 17 Series

that utilizes Puron Refrigerant, is Variable Speed, 2 Stage and qualifies

For a $1,500 Federal Tax Credit

Here are close-ups of the Eternal Hot Water System and Comfort Module

The homeowner also wanted to be able

to control her AC from her cell phone and

laptop because she travels

We utilized state of the art zoning and damper controls



Here are the "after" photos





We built an attic wall to separate the envelope attic from the garage attic.

We do this because it reduces the cost of the foam and there is no need to insulate the garage attic



New Ductwork was installed with the correct size ducts serving each room,

the correct amount of returns, returns in the bedrooms, new grills, boots,

electronic dampers, smart sensor, Infinity Controller, Remote Access

Board, Electronic Damper Board and A fresh Air Duct and damper system 



All bath vents and kitchen exhaust was extended outside.  All soffets 

and roof ventillation was blocked 

Electronic Dampers

One-way, curved-blade supplies.  Adequate return and returns in every room
