Achieving the ideal orientation is about striking a balance between sun, breeze and these other factors. Even while working under these constraints, however, a builder can still create an energy-efficient home through the implementation of energy-saving features, such as low-E windows, adequate insulation, air sealing, and cool roofs. You'll have to pay for some of this content. The Best Orientation When Building a Home. Trees are an important factor in passive solar design because they can both provide needed shade on a balmy summer day and starve the house of natural light when it is needed most. Document each with a qualified team of professionals to understand the ramifications of building in that specific place. With 20% … Download a comprehensive guide to designing more comfortable houses from the Cement and Concrete Association of New Zealand's website. This slight angle depends on the time of year and the observer’s distance from the equator. Dealing with poor solar access. Orientation of building is energy efficient approachas the building orientation saves heating, cooling and lighting cost. You'll need to balance these against the benefits you can achieve through harnessing the sun's energy for heating and breezes for cooling. (a) Design Parameters (i) Building orientation There is an improvement of 3.7 and 3.4 %, if the building orientation is taken as northeast- southwest or northwest-southeast compared to north-south (base case) orientation. Here comes the sun. Street patterns influence the microclimate around buildings and affect access to light, sun and wind. Even if your site isn't ideal for catching the sun (for example because it slopes down to the south), it may be possible to maximise the sun's warmth using north-facing clerestory windows, skylights or position glazing higher in the walls to catch the sun. The relative position of the Sun is a major factor in heat gain in buildings, which makes accurate orientation of the building a fundamental consideration in passive solar construction. Many problems associated with energy and the indoor climate are a function of the site geography and its climatology, and above and below grade geology and hydrology; as well as how the building is orientated on the site in relation to the prevailing flows of natural forces and by-products of man made inventions and interventions. Building Massing and Orientation Ther e is a trade-of f between a compact form that mini-Another energy-related massing and orienta-building, the electrical load and cooling load savings mizes conductive heat transfer thr ough the envelope tion consideration is the seasonal wind pattern. They are important for thermal comfort and low energy consumption. • Identify the direction of the prevailing wind. Determine the weather patterns, climate, soil types, wind speed and direction, heating degree days, and path of the sun. Whether it’s by architecture or other means, the power to harness the sun’s energy and limit the detrimental effects can make a huge difference between a good site and a bad one. Wind angles affect building’s natural ventilation and also energy consumption of the building.

Fig-1: Wind action on various Building Plan forms 3.3 Wind and Built Form Various aspects of the building form can cause increase or reduction in wind effects.
