An Earth Wise Home starts with an air tight thermal envelope.  We use ZipWall coated wall sheathing with all joints taped and sealed to create an air tight thermal envelope.  Every cubic foot of air that doesn't get in is one less cubic foot of air to heat or cool.

We insulate all window and door headers.  It's impossible to insulate these spaces after framing is complete.  We use about 1 roll of insulation per 1000 sf of home insulating these areas.  Imagine removing a few rolls of insulation from the average home and what effect it would have on the utility bill.  That's what has been done to 99% of all homes.

We pre insulate all exterior corners and tees which are rendered inaccessible by the exterior wall sheathing.

We use high performance vinyl windows with hurricane impact glass, low e coating standard and optional Neat Glass. 

Neat Glass is a coating which reacts with the sun's UV rays to decompose organic materials on the glass and cause them to rinse off with the rain.

We use open cell foam insulation for maximum thermal and air infiltration performance.

Windows, doors, and exterior penetrations are caulked and sealed.  Then we test the building with our door fan to make sure we got everything.

We use regular fiberglass batts on interior walls to reduce sound transmission.  This along with solid core doors help reduce noise pollution from inside and outside the home so you can enjoy your private spaces in peace and quiet.

We use our door fan to measure air leakage.  We don't just say we build a high performance energy efficient home.  We prove it!

The door fan draws a 50 pascal vacuum on the building which simulates a 20 mph wind on all 4 sides and top of the home to measure the number of air changes per hour leaking into the home (ACH50).

These are the national performance guidelines:

1.5 - 4 ACH = High Performance Home

4    - 7 ACH = Energy Efficient Home

8    - 12ACH = Standard New Home

11  - 21ACH = Standard Existing Home

18  - 35ACH = Standard Older Home


We use 16 SEER 2 speed heat pumps with variable speed air handlers for quiet energy efficient operation.  Optional electronic air filters can capture and kill airborne contaminates.  Communicating thermostats monitor indoor, outdoor temperatures, and humidity to optimize system performance and interior comfort. 

A high performance heating and cooling system combined with an air tight and thoroughly insulated home creates the conditions for even temperature distribution, lower humidity, and much greater comfort.  We use home run and transfer ducts in all bedrooms to ensure sufficient fresh air flow and an outside air intake duct to ensure full air circulation with fresh and clean indoor air quality.

For beach homes we use 14 SEER units or optional geothermal heat pumps.

We use LED lighting.  This 50 watt incandescent halogen bulb is operating at 313 degrees.  Multiply that by the number of bulbs in an average home and you can imagine how much heat that adds a home vs LED lighting.

This 8 watt LED bulb is putting out the same number of lumens as a 50 watt incandescent bulb and operates at 1/2 the temperature.

Radiant floor heating is a great way to warm up a bathroom and increase comfort in a bathroom or kitchen zone without heating the whole house.  It's so nice to step on warm tile on a cold winter day.

Part of our job is to be good stewards of the natural attributes of your lot.  It starts with determining which trees can be saved then restoring their health. 

Neglected Oaks will tend to be top heavy, unbalanced, and vulnerable to wind damage by hurricanes.  The first step is to create a pruning plan which lifts the canopy, prunes out the weak branches, lightens the load on the tree, and lets air flow through the canopy instead of catching it and stressing the major branches.  Once the tree has been properly pruned, shaped, and balanced you'll be surprised at how these large heritage oaks will perk up and put out lots of new growth and how well they will endure hurricanes. 

You can't buy this type of natural beauty so it's all of our responsibility to preserve what we have, care for it, and be good stewards of our environment.
