Net Zero Building Advisors takes you through the process to determine how to make your building

Net Zero and Maximize LEED points. Home or Commercial minimizing month Cost of OwnershipStep One is to determine the most cost effective shell on these projects

to increasing energy efficiency which is the least expensive way to lower cost

Step Tw0 is analyzing High efficiency HVAC systems to determine the most cost effective system.

Step Three Integrate high efficiency appliances, LED Lighting and High efficiency celling fans.

Step Four Base on a final analysis of the home determine Solar required. With this process should between 3.5 to 7 kw based on home size.

Integrating this process is easiest and cheapest way to achieve as many of 46 potential LEED points as possible, reasonable ROI, and cash flow positive improvements.

We also provide you with the most comfortable and healthy home possible.

Insulation panels with Integrated fastening Strips make insulating basements easy and fast.

Available in panels from 2 to 3 7/8 panels these are an easy way to add 8.5 to 14.8 while reducing thermal bridging by wall framing construction.

When combined with 2 x 6 wall construction with foam insulation gives you R-30 walls for cost effective home. It is not cost effective to exceed this. It is more effective using funds for upgrading heating and solar.

On concrete walls these panels can allow for easy electrical installation.

Window selection on energy usage• In looking at homes many

concentrate on the walls and roof but, because of their insulation values, a small improvement in window can have bigger effect on overall energy usage.

• Most windows selected are in the range of U-.26 as these are the offerings of most of the major window companies.

• Smaller manufactures of now developed more efficient designs bring these to a u-.17

• People believe, due to low percentage of walls this difference does not effect energy usage that much but even on a house with less than 20% windows this difference can reduce energy usage of the home by 10%

• This is more energy saving than taking the side walls for R-20 to R-30 at lower cost.

• This is why, when they decided to replace window, the Empire State building decided this was the most economical way to go.

Variable speed Heat pumps for Heating and Cooling

• Variable speed or soft starts critical to reduce size of system• 2.5-4 Ton Cooling and

heating. Can operate at down to ½ ton.• Can be paralleled to

15 unit• With their Variable

speed design these units can provide heat when outdoor temperature is -14 F

High Efficiency Variable Speed air handlers Fan energy is one of easiest energy

saving area Most ECM controls are designed to

maintain fixed flow which does not maximize efficiency of Variable Speed Heat Pumps.

With high efficiency building constant air movement is critical to maintain comfort throughout home

Using Variable speed temperature controlled fans can reduce energy requirement by over 80% while increasing efficiency of Variable Speed Compressors. Reducing continuous operation from $500/yr for fixed speed, $200 so some Variable designs to under $50 with demand control ECM fans

Allows for smaller air handlers and lower water temperature for heating or cooling increasing HVAC efficiency

Variable Speed Fan Control increases indoor air quality and humidity Control With new Variable Speed Heat pumps they

run at maximum efficiency while provide only the amount of heat needed constantly. This is best controlled by a fan system that run a speed required to provide heat/cooling to facility rather than constant speed. This also maximizes efficiency of new ECM motors.

New Heat pumps controls distribution temperature to precisely maintain humidity level. Low speed air distribution maximizes the effectiveness of this while not blowing condensed water off of coils and into duct system, providing a potential breeding location for Mold.

Low speed air distribution maximizes effectiveness of UV and air treatment system to kill potential harmfully containments. Increasing air quality while reducing disease.

Net Zero Heating System

High efficiency ceiling fans and LED is the cheapest way to reduce home energy usage.

Traditional ceiling fans use 75 t0 100 watts but with these models we can reduce this below 31 watts.

With 6 speeds higher efficiency available

Choose of lighting options with Highest efficiency LED.

Using these lamp can reduce lighting energy usage by 20-80%

Light your home with less than 500 watts of solar panels

LED’s with over 140 lumens/watt efficiency

Standardized Solar system reduces cost while increasing efficiency

Combinations of new high efficiency PERC technology or standard modules gives us flexibility of design.

Packages use low voltage startup inverters with maximized string sizing increases production/watt

Standardization reduces development cost.

Use of high quality flashings insures long trouble free life of system tested with 30 PSI water against leaks
