A simple gable roof is strong and sturdy, and sheds snow easily. A place to discuss news and debate details of the stringent energy efficiency standard, PassiveHaus. 1. Passive and Low Energy Architecture contains the proceedings of the Second International PLEA Conference held in Crete, Greece, on June 28 to July 1, 1983. The book is organized into four parts as the topics of the conference. In this paper, building design in the tropical climate is discussed with reference to the literature and to results from our own case study. A solar heat-gain coefficient (SHGC) below 0.25, and preferably as low as 0.20, should be specified. A light-colored, reflective roof may help to keep unwanted heat out of your house. In the South, I want the lowest SHGC (Solar Heat Gain Coefficient) I can find.  I recently completed a project with all Marvin exterior doors and they sealed up super tight. The case study buildings used an integrated design approach to evaluatethe most efficient energy measures.

Residential Energy: Cost Savings and Comfort for Existing Buildings. Best Practice Guides. How much insulation you need is dictated by the climate zone that you live in. The result of the work shows that it is possible to reconstruct the house into an energy efficient building. House design and . Design for climate means that a home is designed or modified to: use minimal heating or cooling. ENERGY STAR labeled roofings have a solar reflectance of at least 25% (for steep sloped roofs). As with cold climate home building, warm climate home owners need to have a basic understanding of how heat, air and moisture travel within the walls of a home, how insulation and windows are rated, as well as passive energy designs, and energy efficient products and HVAC systems is key. These may include: Asphalt shingles: This roofing material works well in terms of preventing mildew and mold but is energy inefficient; Cedar shake roofing: Easy to replace and energy efficient, cedar shake roofing is a popular choice in Louisiana In hot, humid climates, the majority of the energy used to make the house comfortable is spent on cooling and dehumidifying the house. Project: Compact Buried Ducts in a Hot-Humid Climate House (Lady’s Island)Builder: K. Hovnanian HomesProfile: Home Innovation Research Labs partnered with K. Hovnanian Homes to demonstrate a new buried-duct design that is durable, energy efficient, and cost-effective in a hot-humid climate. commercial buildings designed for hot/humid climates. By following these steps, you can build a new home that is affordable to build and cost less to own. The house should also be airtight, so that when you want to close up the house during the day to keep heat out, you can do so.

Houses use 22 percent of the energy consumed in the United States today. The philosophy behind design decisions is explained with stories, photos, sketches, and checklists. The book is divided into Twelve Lessons, with an additional Bonus Lesson ," Building Green, Naturally". It's hard enough to control humidity in humid climate homes when they're just built to code these days. performance of energy-efficient technology packages designed for a production builder in a hot-humid climate. • The efficiency of a hot water system is rated in stars. Ikaros House. Use Vegetation to Increase Energy Efficiency. Most houses in the South are either Concrete Slab or Pier/Beam.

Orientating a building to take advantage of how the sun moves across the sky is the easiest and most effective passive design strategy. Marine (C) This is the Goldilocks climate, in a way. It's not too hot in the summer (warmest month mean temperature < 72° F), not too cold or too warm in winter (between 27 and 65° F), has at least four months with mean temperatures above 50° F, and has its dry season in the summer. Top. Climate-specific guidelines must be considered during the design process of high- performing building enclosures (Oral et al., 2004). Dark colors generally absorb heat from sunlight, whereas light surfaces reflect heat and reduce cooling costs. Climate Zone 5 consists of regions of the country that experience warm summers and cold winters.  Running ducts in the attic also sets your house up for depressurization because those duct will leak cold air into the attic and your house finds a way to make up that loss by leaking air back down into the house. less energy at home, you help reduce the emissions that contribute to global warming. Project: McKinley Project - GarlandBuilder: Carl Franklin Homes, L.C. Build Tight: Hot air leaking into your air-conditioned building is a major energy drain for your house. To even out temperature swings, south-facing glass (with overhangs sized to admit winter sun) on the main living space should be coupled with thermal mass, such as tile or brick on a slab floor or a masonry partition wall.

It is here for you today, and can easily provide up to 50% of your space and water heating requirements. This is a book that simply and clearly explains the principles of using solar energy to heat your home. In warm climate regions such as the Gulf where temperatures are high year round, designing for the climate means designing to reduce heat gain is the first priority. The hot-humid climate package of measures meets and exceeds DOE’s Zero Energy Ready Home program requirements. In a northern climate, R-40 in the walls and R-50 or more in the ceiling or roof makes sense. Through energy-modeling software, architects Doug Zaun and Rachel Wagner designed an energy-efficient home in Duluth, Minn., that met the owners' needs for a house big enough for their family but that didn't bust their modest budget. Overall house design: The more surface area the building envelope has the more heat gain and loss. Design to minimize west and east glass and wall surface, and shade it.  It’s a double whammy of inefficiency.
