Why Should a Building be Protected From Water?

You’ve spent a lot of time and resources making your home into the wonderful place that it is. Protect your investment by preventing the havoc that water damage can do your home! Structural Damage.  Deficiencies such as leaking roofs, clogged gutters, poor site drainage, and even moldy, damp crawlspaces and basements can lead to permanent structural damage, costly repairs and interior moisture problems. Water is a building’s most serious enemy and proper water management is essential to effective building maintenance. To remedy the problem, roofs should be checked periodically for damage and repairs made as necessary.  Gutters should be cleaned several times a year and downspouts should discharge at least 10 feet away from the building and on a down-slope.  Poor site drainage should be improved by grading or installing drainage ditches or French drains. Moisture.  Moisture problems in buildings can result in the growth or amplification of biological and microbial organisms like mold, mildew, dust mites and pet dander and indoor air quality problems. Common sources of moisture include high indoor humidity, plumbing leaks, and water leaks. Poorly maintained heating, ventilation and air-conditioning systems can also contribute to moisture problems and leaky ductwork and gaps in the building shell can allow mold from crawlspaces and attics into the building. To remedy the problem, the source of excess moisture and the leaks must be found and fixed, and contaminated materials must be removed and discarded if they can not be thoroughly... read more

Raising the Bar: Version 3 Specifics

Version 3 extends national program qualifications to ensure tighter building envelopes, require more efficient HVAC equipment, and improve indoor air quality and occupant health through water management and provision of fresh air. Where Version 2 called for 5 or more ENERGY STAR® qualified appliances in a new home, Version 3 requires all refrigerators, dishwashers, ceiling fans, and exhaust fans to be ENERGY STAR approved, in addition to ENERGY STAR light bulbs and fixtures in 80% or more of RESNET-defined qualifying light fixture locations. The home energy rater’s Home Energy Rating System (HERS) Index remains the primary measurement tool for ENERGY STAR home certification. Builders must submit the home’s architectural plans to the rater for review and analysis, which includes modeling the home’s energy performance using a RESNET-approved software program and information obtained during field testing. A score is derived from this model, which is referred to as the home’s HERS Index. This index must fall within an acceptable range in order for the home to receive the ENERGY STAR label. During field testing, a RESNET-certified rater must use RESNET-approved testing protocol to determine a home’s envelope leakage. The target leakage level was bumped down a notch (1 ACH50) in each climate zone in EPA’s most recent requirements. To achieve certification, the home’s leakage rate must be equal to or less than the target leakage level. The builder must complete the Water Management System Builder Checklist, which documents conformance with best building practices and materials to protect roofs, walls and foundations from water damage. The integrity of the home’s building shell, its general air tightness, insulation levels and quality are... read more

Value Engineering

Value engineering is defined as an analysis of the functions of a program or project, directed at improving performance, reliability, quality, safety, and life cycle costs. It is widely used in industry and government as an effective technique for reducing costs, increasing productivity, and improving quality. For the building industry, it can be used to achieve economy, utility, durability and comfort. Value engineering is directed toward achieving best value between worth and cost. The use of value engineering can yield a better value when construction is approached in a manner that incorporates environmentally-sound and energy-efficient practices and materials. With value engineering, we improve the construction process to achieve the best value for the lowest cost. This includes implementing specific value engineering tasks such as advanced framing and green... read more

At Green River…

We provide energy and environmental consulting services to residential and commercial customers, helping to lower utility bills and improve occupant comfort and health. We use building science to address problems such as moisture, mold, and energy loss, ensuring we address the cause, not the symptom, when taking action, so our remedies are long-lasting—giving you the most benefit for the money spent!

We also provide quality construction services to repair, retrofit, weatherize and remodel existing buildings with an emphasis on environmentally-sound green building practices. Eco-friendly doesn’t necessarily mean more expensive, either. In fact, it saves money, by lowering the cost of utilities, keeping you healthier, and improving the value of your home!
