They have adapted a "Passive House" for certification from a Passive Solar House, a good text by Edward Mazria, "The Passive Solar Energy Book" which is a natural use of heat\cooling and natural convections, conduction, radiation and the physics of heat transfer. The hybrid HVAC is complex and deserves a qualified engineer to design. However the duct, plumbing and electrical runs can present a problem in design and building of an efficient and effective systems. Autodesk REVIT does have tools to meet many of these challenges but hands on building experience if these printed pictures and specifications are easily built with a hammer and saw should reflect on the design or use. It creates a real footprint. It is up to the customers wants and needs to achieve a net-zero house but some practices can interfere with the sufficiency of a sustainable building.
https://lnkd.in/dExKMyH9 A Passive House is a highly energy-efficient building standard that prioritizes both environmental sustainability and indoor comfort. Unlike traditional structures that rely heavily on active heating and cooling systems, Passive Houses maximize the use of “passive” influences such as sunshine, shading, and ventilation. Here are some key features of Passive Houses: 1. Energy Efficiency: Passive Houses use intelligent design principles, including proper orientation and shading, to minimize energy consumption. Coupled with very high levels of insulation and airtightness, these homes can use up to 90% less energy than typical dwellings. 2. Indoor Comfort: Consistent temperatures and excellent air quality are hallmarks of Passive Houses. The high insulation levels also contribute to reducing both external and internal noise, creating a serene living environment. 3. Criteria for Passive House Certification: Space Heating: The energy demand for space heating must not exceed 15 kWh/m2 of living space per year, or 10 W/m2 at peak demand. Primary Energy: The total energy needed for all domestic applications (heating, hot water, and domestic electricity) must not exceed 60 kWh/m2 of living space per year. Airtightness: Passive buildings maintain very low air leakage, with no more than 0.6 air changes per hour at 50 pascals of pressure. Thermal Comfort: Living areas should remain comfortable throughout the year, with no more than 10% of hours exceeding 25 °C. #PassiveHouse #EnergyEfficiency #SustainableLiving #ComfortableHomes #EnvironmentallyFriendly #Airtightness
