This paper reviews examples of vernacular architecture and its building elements in Nepal and analyses in a qualitative manner which bioclimatic design strategies were applied. The capturing of heat in thermal mass is best suited to regions with sunny days and cold nights. Climate responsive architecture takes into consideration seasonality, the direction of the sun (sun path and solar position), natural shade provided by the surrounding topography, environmental factors (such as wind, rainfall, humidity) and climate data (temperature, historical weather patterns, etc.) One of the hardest climates to build for is a cold one; the wrong design could leave you with a cold home, dripping walls, peeling paint, colds and other mishaps. While those papers offer design recommendations on how to design energy efficient or sustainable buildings, none of those abovementioned studies caters to the cold semi-arid climate of Pakistan. Predominantly, Indian subcontinent is divided into five climate zones, viz. Cold Climate Region The principle of maximum heat gain and minimum heat loss, stands out in build-ing designs in these regions because of the rainy and cool weather. Heat loss should be reduced The region is mountainous, has little vegetation, and is considered to be a cold desert. The solar radiation is generally intense with a very low percentage of diffuse radiation. Architecture can be used as a tool to make homes better equipped to bear it. Below are some ways architectural design can be used to accommodate cold climates. However, the underlying principle remains the same, maximising amount of solar radiation in winter and minimizing the amount in summers. Building designs vary according to context of its location and climate. With many passive strategies, there is a trade-off between heating performance and cooling performance. ... making a woodstove an appealing option for heating a cold-climate home — especially if you have easy access to firewood. The thermal mass acts as a heat bank, storing the warmth from the sun during the day. Laura Gaskill December 26, 2013. For the warm temperate climate bioclimatic analysis brought out the following design strategies: solar passive heating for winter, protection from the cold and rain, high thermal mass, enhanced air movement and medium sized windows with shading in summer. Cold Weather Construction Issue#5: A Cold Roof is a Good Roof. to design comfortable and energy-efficient homes. Reduced sunlight hours in winter and the need to reduce heat loss through window surfaces create unique challenges. Yoshino, H. View all product details Reduce the U-Value of glazing and also lower the SHGC except for the cold climate where higher SHGC is recommended. BSC Mini Split in Cold Climate Building America Report Just to keep folks in the loop, BSC's Building America report on monitoring the Massachusetts (Zone 5) houses built by Transformations (Carter Scott) is currently posted on BSC's website--Carter conditioned most of his houses with wall-hung mini splits, typically two in a 2 story house; more on spread-out floor plans. Regions having similar characteristic features of a climate are grouped under one climate zone. The book also includes an appendix with seven case studies of buildings located in cold and extreme cold climates. 15 Smart Design Choices for Cold Climates Keep your home safe and comfortable in winter by choosing the right home features and systems. )Homes in colder climates use more energy for heating than those in warmer climates use for air-conditioning. The six climates are normally designated as Hot and Dry, Warm and Humid, Moderate, Cold and Sunny, Cold and Cloudy and Composite. Cold climate strategy #3: Achieve optimal design for window, solar heat gain, daylight, and views. Insulation: A good passive design strategy in summer in these regions is to shade and insulate the house against the heat of the day and flush out any stored heat during the cooler nights. NY-91-07-4 -- Design Strategies for Houses in Cold-Climate Regions of Japan; NY-91-07-4 -- Design Strategies for Houses in Cold-Climate Regions of Japan Conference Proceeding by ASHRAE, 1991. DESIGN STRATEGIES IN TEMPERATE CLIMATE 1.Urban orientation. Hot and Dry, Warm and Humid, Temperate, Composite, and Cold. In predominantly hot regions, buildings should be ideally oriented to minimize solar gains, the reverse is applicable for cold regions. In the hot period shading and wind cooling is the priority, while during the cold season, the winter sun must be exploited for the heat but protection from the cool winds is obligatory. Geographic coordinates of Leh, India. When the climate is not extremely cold or hot, architects experience greater design freedom in choosing materials and strategies. The warm-humid climate zones are ... Another advantage is that they have a good resistant level while they come in a wide range of colors and designs. In addition to cold-climate considerations in HVAC calculations and system design, this book's chapters cover sustainability, controls, building design, and commissioning, all from this distinctive climatic perspective. Passive Design: Strategies in Architecture by William A. Womeldorf - Page 4 Landscaping – Using trees and vegetation as a passive Passive Venting Systems - Another passive design effort design strategy is a great way to effectively shade a space to control the comfort … Cold climates present designers with the problem of properly balancing the prioritization of the design to achieve successful passive solar heating, with strategies for passive cooling. Sustainable design strategies for ... should be placed preferably on southern or northern slopes, ideally facing away from the equator. Building a home in a cold climate, like northern Minnesota, can be a lot different than building a home in a warm climate. T o evaluate the bioclimatic or climate-responsive building design strategies for Nepal, local climate data . An exploration into finding different combination of these strategies in modern design might unravel a solution for a completely passive design. Further exploration is required to understand the other strategies apart from the thermal performance of materials, layout and shading; in order to fully comprehend the combined effect of these strategies. Chrysalis Childcare Centre / Collingridge and Smith Architects Mountainous weather can be difficult to build for, as it experiences drastic temperature variations in one day. In the evening, as the temperature drops, the heat is gradually released maintaining a comfortable internal temperature and reducing the need for mechanical heating. The building type and operation determine which strategies will have the best overall impact on energy performance. If the number of heating degree days greatly exceeds the cooling degree days, then logically decisions in the design of the building, orientation and envelope should favor passive heating. In general cases, specify low U-values for residential applications. Instead the modern building design is dominated by universal architecture that neglects local climate conditions and traditional construction techniques and materials. Thus, building in cold climates to achieve high performance is the result of designers and contractors working together to achieve a desired result. The focus is to keep heat gain in the building. Under each State’s legislation and the BCA, there are different construction requirements for each of these zones. Cold climate strategies balance the need for daylight and views. Bioclimatic design strategies in temperate climate Consistency of passive cooling and heating YUICHIRO KODAMA Building Research Institute Tatehara l, Tsukuba, 305 Japan phone: +81-298-64-6750 fax : +81-298-64-6775 e-mail: kodama@kenken.go.jp Abstract Ranging from cold snowy winter nights to often dry and hot summer days, Charles Cunniffe Architects has mastered the design of mountainous dwellings. Even lower values may be desired in extreme heating climates. As introduced in the attached PowerPoint presentation, Harbin is in the far north of China where it is quite cold, Guangzhou is located the south in a tropical climate, and Urumqi is in far western China in a drier climate. Design considerations for day-lighting in cold and cloudy region: Ensure openings to admit solar light and retain it. Passive Design Strategies. An owner must have an architect who can design a high performance building, and an owner must have a contractor who can faithfully build that design. Climate; Geographic Diversity; Climatic Zones in India; Hot and Dry; Cold and Sunny; Warm and Humid; Cold and Cloudy; Composite; Moderate; Leh, Cold and Sunny. (You can find the heating and cooling dominance of your state here. Multi-layered and nested interior spaces that keep the heat inside and the cold air outside should be designed in cold climate regions. Mean Monthly Temp. These climate zones range from the cold alpine areas of the Snowy Mountains through to the hot, tropical conditions of the Northern Territory. Integrate active and passive solar strategies such as sunspace and solarium with day-lighting strategies. He doesn’t say exactly where, but conditions are certainly challenging: high heat and high humidity, with nighttime temperatures dipping only into the upper 70s and outdoor relative humidity hovering at about 70%. It’s generally accepted that homes use more energy in climates that require more heating than cooling.Wisconsin is a good example of a heating-dominated climate, while Florida is clearly cooling dominated. But it does, and that’s because solving the roof causes of ice dam formation is best done at the initial design stage. Best Strategy for a Crawlspace in a Flood Zone AlbertoArriaga33 is wrestling with plans for a new home in a tropical location. In winter, dry, sunny days provide plenty of opportunity to capture and store solar energy in a solid material such as a concrete floor or brick walls (thermal mass). picpics Save Photo. Following are two examples of how to approach this climate. Top lighting strategies such as skylights—domed or pyramid shaped—with baffles to control glare are more efficient. Latitude: 341000 N Longitude: 773459 E Elevation above sea level: 3599 m COLD AND DRY The cold and sunny type of climate is experienced in Leh (Ladakh). passive design strategies for a high-rise residential building in the hot and humid climate of China [37].
