Passive design is a system or structure that directly uses natural energy such as sunlight, wind, temperature differences or gravity to achieve a result without electricity or fuel. Continuous insulation means the building is essentially wrapped with a blanket of insulation outside the structure to thermally separate the inside from the outside with no thermal bridges. Finding the right combination of active and passive strategies to incorporate into a project comes down to balancing the budget, program and the specifics of the site and microclimate. In such … Active design strategiesuse purchased energy to keep the building comfortable. “Some faces of a building are more prone to heat gain or loss,” he explains. Resource conservation. Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. “Passive design strategies take advantage of natural energy opportunities as they relate to the location of the building’s site, the local climate (and the site’s microclimate, if relevant), and the properties of building materials,” notes Christine Robbins-Elrod, AIA, LEED AP BD+C, WELL AP, GACP, associate principal at 5G Studio Collaborative in Dallas. For the 45 strategies, a Strategy Index for … Direct sun can generate the same heat as a single bar radiator over each square metre of a surface. The passive building designer uses software and design methods to adjust multiple variables—insulation R-values, wall construction parameters, etc.—until the design model meets the energy performance targets. Active strategies usually consist of heating and cooling systems, while passive design measures include building orientation, air sealing, continuous insulation, windows and daylighting, and designing a building to take advantage of natural ventilation opportunities. Passive design strategies use ambient energy sources instead of purchased energy like electricity or natural gas. As we know, FenestraPro is a design tool that can promote passive design strategies – whether that be controlling internal heat gains, the design of sun shading, thermal comfort requirements, or optimizing natural daylight within a space. Passive design strategies and deficient energy requirements. These strategies include daylighting, natural ventilation, and solar energy. ZCP's Design Strategies.
