This Cold House


Book Description

Does turning the thermostat down on a winter's night offset the costs of reheating the house in the morning? What will best prevent energy loss: new windows or insulation in the attic? Is heating oil cheaper than natural gas? Blending science with anecdote and example, Colin Smith answers questions like these, providing an insightful guide to creating an environmentally friendly home without sacrificing comfort. This Cold House helps homeowners identify heating and cooling priorities and choose the most appropriate methods, tools, and equipment. Basic equations allow you to estimate possible savings in annual heating and cooling bills and determine payback times for improvement projects. Practical and entertaining, This Cold House illuminates the concepts behind energy efficiency and translates them into ideas you can use, whether you live in a castle, igloo, or house. -- Dan Holohan




HVAC Cooling Loads


Book Description

LEARN howto size your Industrial, office or home HVAC (air-conditioning) Unit. HVAC - Heating, Ventilation & Air-conditioning It's that time of year again when the weather starts to cool off and we start thinking about turning on the heat. But before you do, it's important to understand how heating and cooling loads affect your HVAC system. Heating and cooling loads are the amount of heat that must be added or removed from a space to maintain a comfortable temperature. The load is affected by a number of factors, including the size of the space, the insulation of the walls and ceiling, the number of windows and doors, and the amount of sun exposure. When the load is too much for the HVAC system to handle, the space will become uncomfortable and the system will have to work harder to maintain the temperature. This can lead to higher energy bills and premature wear and tear on the system. To avoid these problems, it's important to have your HVAC system sized properly for the space it will be heating or cooling. An HVAC contractor can help you determine the appropriate size for your system.




Energy Savers


Book Description

A large portion of the energy for which the typical U.S. family pays is wasted, such as through poorly insulated windows & doors. By using a few inexpensive energy-efficient measures, you can reduce your energy bills by 10% to 50%, & at the same time, help reduce air pollution. The key is a whole-house energy efficiency plan. View your home as an energy system with interdependent parts. You may have a top-of-the-line, energy-efficient furnace, but if the ducts leak & are un-insulated, & your walls, attic, windows, & doors are un-insulated, your energy bills will remain high. Covers: insulation & weatherization; heating & cooling; water heating; windows; landscaping; lighting; appliances. Illustrations.
