Conservation Subdivision Design

Conservation development permanently preserves 50-70 percent or more buildable land than a conventional development, while allowing the same number of homesites. These creative developments are often more profitable and faster selling, benefiting the landowner, developer, homeowner, community and wildlife.

In subdivisions designed for conservation:
  • Homes are placed for the best views of nature and wildlife
  • Homes are placed for maximum privacy from neighbors
  • Forests, fields and trails get children outdoors and offer homeowners the chance to enjoy nature, improve health and reduce stress
  • Trees are preserved
  • Developers' costs are reduced
  • Lots may carry a premium and sell more quickly
Did you know... every year, millions of acres are developed into subdivisions?

Insulating Concrete Forms

ICFs are hollow foam blocks that are stacked in the shape of the exterior walls of a building, reinforced with steel rebar and filled with concrete. The result is a wall system of unmatched comfort, energy efficiency, strength and noise reduction. Build Block ICF walls actually perform as high as R-50 in some areas of the country.


     Building your home with ICFs:
  • Can reduce heating and cooling costs by at least 50 percent
  • Reduces air infiltration (including airborne allergens) by 75 percent
  • Creates a more uniform and stable temperature
  • Substantially reduces noise
  • Makes it ten times stronger than a wood-framed structure
  • Makes it fire, earthquake, tornado and hurricane resistant (and may qualify for a lower insurance premium)
  • Saves trees and energy
  • Adds value to the home

D.R. Nelson Sealant Package

Nelson Energy Seal is the strategic application of UL-listed sealants at two critical stages of the construction process. This eliminates sources of excessive air leakage, the single most significant impact on the performance of the home because it degrades the actual R value of the insulation, increases the load on the heating and cooling systems, and allows moisture, dust and insects a free path into the home.

The Nelson Energy Seal creates a "skin" to contain the home's conditioned air:
  • Promoting energy efficiency
  • Lowering heating and cooling costs
  • Improving indoor air quality
  • Improving homeowner comfort
To ensure proper sealing, D.R. Nelson tests all of its homes.

Blower Door Test
A blower door test determines a home's airtightness and pinpoints leaks. A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. Measurements taken during the test are used to calculate the leakage rate. Identified leaks can be sealed to improve the home's tightness.

View Slide Show of blower door test.

Did you know... excessive air leakage accounts for 40-60 percent of the home's heating and cooling costs, and reduces the actual "R" value of insulation by as much as 70 percent?

Bonus Room Construction

Bonus rooms are designed, constructed, insulated and sealed with the same building practices as the rest of the home to ensure comfort and safe air quality.

Did you know... the temperature in a conventionally constructed bonus room can vary 10-15 degrees from the rest of the house?

Low-e Glass

Low-emittance (low-e) coatings are microscopically thin metal or metallic oxide layers deposited on a window or skylight to regulate heat flow through the window.

These energy-efficient windows:
  • Reduce energy loss by as much as 30-50 percent
  • Reduce air leakage
  • Reduce condensation
  • Reduce fading of interior furnishings
  • Make a home more comfortable
  • Can save more than 30 percent on annual heating costs
Did you know... on a night with an outside temperature of 0 degrees and a 15 mph wind, the inside temperature of a single pane window would be approximately 26 degrees? Regular double pane glass might be 35 degrees. Hard-coat (tin-based) low-e glass would be near 49 degrees and soft-coat (silver-based) low-e glass at 62 degrees.

Geothermal Heating and Cooling

Geothermal, or geoexchange, technology uses the earth's natural, renewable thermal energy to provide extremely efficient heating and cooling. In winter, the earth's heat is collected through a series of pipes, called a loop, buried in the ground and carried into the home. A heat pump inside the home concentrates the energy and transfers it to air circulated through standard ductwork. In the summer, the process is reversed: excess heat is drawn from the home, expelled to the loop and absorbed by the earth. The only external energy needed is a small amount of electricity to operate the ground loop pump and fan.


Heating and cooling your home with geothermal technology:
  • Saves 30-70 percent in heating costs and 20-50 percent in cooling costs, according to the U.S. Environmental Protection Agency
  • Has the lowest cost of operation of any heating/cooling system available
  • Produces no gaseous emissions—is completely nonpolluting
  • Is quiet, highly reliable and requires little maintenance
  • Uses less space than a furnace and air conditioner—the compact heat pump typically is installed in a basement or attic
  • Uses energy efficiently and produces fewer emissions
  • Adds value to the home
Did you know... the temperature a few feet below the earth's surface remains relatively constant throughout the year?

Hydronic Heating

Hydronic, or radiant floor, heating concentrates heat in the floor of the home. Special tubing is embedded in a concrete foundation or in a thin concrete mixture on top of a wood-framed floor. Heated water flows through this tubing, warming the thermal mass of the concrete, which radiates heat to the room.

Hydronic heating:
  • Is efficient
  • Is comfortable—heat is at your feet and gently warms the room
  • Can be easily zoned
  • Is cleaner than ducted systems (which circulate dust, dirt and impurities back into the house)
Did you know... water is the ultimate transfer medium? A given volume of water can hold almost 3,500 times as much heat as the same volume of air for the same temperature rise.

Low-flow Plumbing

In 1995 the National Energy Policy Act mandated the use of toilets that use no more than 1.6 gallons of water per flush. Since then, low-flow plumbing fixtures have helped homeowners save substantial amounts of fresh water while reducing utility bills.
  • Low-flow toilets use 1.6 gallons/flush compared to the standard toilet's 3.5 gallons/flush.
  • Low-flow showerheads use about 2.5 gallons/minute compared to 4 to 5 gallons/minute for older models.
  • Low-flow faucet aerators use 2.5 gallons/minute compared to 4 gallons/minute for older models.
Did you know... low-flow toilets alone could save up to 22,000 gallons of water per year for a family of four?
