Guidelines for Energy Efficient Construction In most construction projects, whether for a new building, a building addition or a major renovation, there are thousands of issues which must be resolved by the building owner, the design professionals and the construction contractors. A large number of these issues deal with the design, selection and integration of the building's energy systems (the building shell, the heating/cooling/ventilation systems, the lighting and other energy-consuming equipment and appliances). Typically these issues get very little attention in the design process. This is a serious and costly mistake because over the life of a building, the energy costs alone will exceed the initial cost of all of the energy systems. NESIP is committed to helping nonprofit organizations design comfortable and efficient buildings and has prepared this document to educate nonprofit directors and boards about good energy design standards and practices.
Heating & Cooling Systems: Saving Energy and Keeping Safe This worksheet helps you identify possible problems with your home heating system, duct system, and the house envelope (the foundation, floors, walls, ceilings, and roof). By keeping your system in proper order, you can avoid unhealthy situations, reduce energy bills, increase your comfort level, and prevent structural damage.
Heat Pipe Effectiveness Study - Gulf Breeze Laboratory Installation, Pensacola, Florida On October 1, 1996, a Dinh-style heat pipe dehumidification system was installed in the air handling system in Building 49 at the Gulf Breeze laboratory in Pensacola, Florida. The heat pipe was installed to increase the dehumidification capacity of the central cooling system without additional energy consumption. The purpose of this study was to determine the dehumidification effectiveness of the heat pipe installation. The effectiveness was calculated by monitoring temperature and humidity levels of the outside and supply air, and by monitoring the load on the cooling coils and the load on the heat pipe during a two-week period.
Heat Pipe Technology, Inc. (HPT) Heat Pipe Technology, Inc. (HPT), formerly the Dinh Company, Inc., was founded in 1983, in Alachua, Florida, USA. HPT markets a revolutionary line of heat pipe air conditioning and dehumidification products for industrial, commercial and residential applications. The products the company provides are based on patented technologies which represent major breakthroughs in the Heating, Ventilating and Air Conditioning (HVAC) industry, combining higher indoor air quality with enormous energy savings.

HUD Rehabilitation Energy Guidelines for One-to-Four Family Dwellings (on diskette) Determine which energy improvements are cost-effective. The guidebook and Microsoft Excel worksheet diskette allows the user to calculate which enery consevation improvements are cost-effective when properties are rehabilitated. The information is applicable for all climates, from Florida to Alaska. The information is presented in a manner so that owners of building can better assess the needs and opportunities of a particular renovation project. They will also be able to ask better question of designers, builders, and contractors. The guidebook explains how properlly rehabilitating dwellings can increase energy efficiency and reduce costs. It discusses the issues and factors that determine how much energy a building will consume, including heat flow, air leakage, insulation, and heating and cooling systems. The guide also includes the specific HUD Rehabilitation Energy Guidelines for Dwellings with general and location-specific recommendations for energy conservation improvements. These guidelines are followed by examples of typical energy conservation measures in different climates. Each of these examples includes a Cost Effectiveness Excel Worksheet to show the overall simple payback. This easy-to-use worksheet walks through the entire evaluation process. The user simply enters in the appropriate information, much of which is menu driven. Appendicies provide a table that shows counties nationwide by climate zone, a list of resources, a glossary, and sample surveys and worksheets to help owners with their rehabilitation projects.

Innovations in Heat Pumps and Air-Conditioners Since the introduction of air-source heat pumps to the marketplace in the 1950s, nearly one-third of all homes built today in the United States has at least one heat pump. The convenience of a single appliance that delivers both heating and cooling appeals to a growing segment of builders and homeowners, particularly those building new homes or replacing older Heating, Ventilation, and Air Conditioning (HVAC) systems. Many electric utility companies also offer rebates for higher-efficiency heat pumps (those with a Seasonal Energy-Efficiency Rating—SEER—of 12 or higher). Even with these advantages, however, many heat pump owners still complain about noisy operation and inadequate heating performance. The sections here describe some of the recent improvements in heat pump technology that address these complaints.
Innovative Townhouses Construction has begun on a group of four research townhouses, called the Twenty-First Century Townhouses, that the Research Center is building in the NAHB National Research Home Park in Bowie, Maryland. The townhouses will feature alternatives to dimensional lumber, and innovative approaches to achieving advanced energy efficiency.
Insulating Foundations An uninsulated foundation may account for up to 50% of the heat lost from an otherwise tightly sealed, well-insulated house. One way to combat this and make above-grade spaces more comfortable, is to insulate the foundation. This can also be a low cost way to increase a home's useful living space.
Insulation Fact Sheet Electricity bills, oil bills, gas bills--all homeowners pay for one or more of these utilities, and wish they paid less. Often many of us do not really know how to control or reduce our utility bills. We resign ourselves to high bills because we think that is the price we have to pay for a comfortable home. We encourage our children to turn off the lights and appliances, but may not recognize the benefits of insulating the attic.

Investing in Energy Savings: Overcoming the Barriers For years, energy conservation and energy efficiency gurus have urged us to save energy in our homes and businesses. The opportunities to reduce our energy use and to cut our energy bills are truly staggering. Many steps, like properly maintaining equipment, cost little or nothing, yet result in considerable savings. Many other efficiency measures pay back their costs in months and generate savings for years. The return on investment from some efficiency measures can be over 100%, an undeniably impressive return! Despite this large return, many of us fail to do the right thing in our homes and our offices.
Landscaping for Energy Efficiency Are you looking for cost-effective yet eye-pleasing ways to lower your energy bills? Planting trees, shrubs, vines, grasses, and hedges could be the answer. In fact, landscaping may be your best long-term investment for reducing heating and cooling costs, while also bringing other improvements to your community.
