ZERO ENERGY HOME
STAPLETON’S CENTRAL PARK WEST NEIGHBORHOOD
Imagine living in a brand new Stapleton home and never paying an electric or gas bill. New Town Builders is building its Zero Energy Home in Stapleton’s new Central Park West neighborhood to demonstrate that zero energy homes are now within reach of the home-buying public. It’s true! New Town is offering the Zero Energy option on all our single family homes in Stapleton!
New Town Builders is Stapleton’s most energy efficient builder. This efficiency is achieved by constructing the homes with the following characteristics:
• Homes that meet or exceed current Energy Star® requirements.
• The frame of each home is turned into an insulating envelope to keep the outside air out and inside air comfortable.
• Heating and air conditioning ducts are checked for tightness so heated or cooled air reaches its destination with 7% or less loss.
• High efficiency furnaces, air conditioners and water heaters are included.
• Each home includes a photovoltaic electricity generating system on the roof as a standard feature.
The Zero Energy Home is taking New Town’s energy efficiency to a new level. New Town began discussing the construction and demonstration of a Zero Energy Home over two years ago and looked to NREL, the National Renewable Energy Lab in Golden, Colorado for assistance.
The Zero Energy home has four goals.
1. To generate as much energy as it uses over the period of a year. This is measured by the Home Energy Rating System, also known as a HERS rating. Homes in Denver’s older neighborhoods typically have HERS scores between 100 and 200. New homes built today based on Denver’s current building code have a HERS rating of 100; thus, a lower rating is better. Energy Star requires a HERS rating of 85. All of New Town’s single family homes achieve HERS ratings in the low to mid 50’s. New Town’s Zero Energy Home will achieve a HERS rating of 0 by building to even higher levels of conservation and generation.
2. To insure an attractive and comfortable home in which to live. This will demonstrate to the consumer that a Zero Energy Home isn’t some unique one-off design that people would find unattractive. To accomplish this New Town is using one of its existing plans with a modified exterior wall, so it will live like and look like any other New Town home.
3. To find a cost effective design that can be constructed within the normal processes of a production builder so that New Town may offer this feature to the market on an economically viable basis.
4. To create a home that does not burden the homeowner with complicated, exotic systems that require constant monitoring and maintenance. In fact, the Zero Energy Home may require less maintenance than the average home because of the high standards of construction.
New Town’s Zero Energy Home is one of three new Model Homes within Stapleton’s Central Park West neighborhood. Beyond the current New Town construction standards, the Zero Energy Home will include:
• New Town’s proprietary wall system creates more space for insulation in the exterior wall.
• An increase in the heel height of the roof’s trusses allows more space for insulation.
• Spray foam insulation at all seams.
• Increased attic insulation, exterior wall insulation and foundation wall insulation. foundation insulation.
• More energy efficient widows with decreased U-value.
• Increased Solar power system with 8-9.5 kilowatt panels.
• Even higher efficiency mechanical systems including:
• Tankless hot water system (per plan)
• 96% efficient furnace
• 16 SEER or better air conditioning unit
• Panasonic Whisper Green continuous ventilation fan in lieu of a fresh air ventilator.
• Energy Star appliances including refrigerator and dishwasher.
• 100% CFL lighting, eliminating incandescent lighting.
• Every New Town home’s energy efficiency is certified by an independent third party energy auditor.
Many consumers know that advances in building science have made building zero energy homes possible. What New Town’s Zero Energy Home will demonstrate is that zero energy homes are beautiful and affordable. Stapleton and New Town will be the first and only place we know of that everyday homebuyers can see and purchase a home that is truly at the state of the art of building science. The Zero Energy Home will demonstrate how New Town makes saving energy beautiful.
