We have already looked at the Passive House concept. In this new blog post we are going to be talking about Passive House and Technology by answering the following question: what are the advantages of Passive House and Technology? Keep reading and find out how Passive House and Technology can help you to #ONEUPYOURBUSINESS!

WHAT ARE THE ADVANTAGES OF PASSIVE HOUSE AND TECHNOLOGY?

As we have explained in other blog articles, the Passive House is a building concept that offers ultra-low energy consumption and improved comfort and health for occupants. Passive House buildings follow principles of low-volume heat recovery ventilation systems and tightly controlled rates of air infiltration, which allow the buildings to reduce carbon footprint. Adopting the Passive House concept makes for a greener future as it is committed to improved energy efficiency and below, we discuss the advantages of Passive House and Technology:

  • BIM provides Construction and Quality assurance: the Passive House concept promotes designers to consider all aspects of the design in the early design stage. BIM (Building Information Modeling) helps with accurate visual representation of the buildings to provide different types of precise calculations such as areas, volume and distances. These can guide designers to make their design decisions with confidence and meet the Passive House concept requirements
  • IoT supports occupant wellbeing: Passive House buildings can have high quality ventilation technology with a heat recovery system, offering natural ventilation during summer and great indoor air quality. The air is continuously being removed from the kitchen, bathroom, toilet and other rooms with high pollution and humidity whilst fresh and unused air is supplied to the living room bedrooms and functional rooms, helping to supply fresh air without consuming high amounts of electricity and without much noise. Therefore, ventilation systems are key technology to provide fresh indoor air and Internet of Things (IoT) enabled sensors can support occupant health by gathering real-time environmental data on the ventilation, air quality, and temperature levels and allowing them to monitor the air quality and make any necessary adjustments to provide a healthier environment
  • IoT ensures high level of quality and comfort: with airtight construction and high-quality ventilation technology providing air quality control measures and eliminating cold corners and heat losses, Passive House buildings can ensure there are high levels of quality and comfort and better the health of occupants as the principles help to prevent damages that happen due to moisture build up. IoT sensors and smart buildings such as Atamate and Wondrwall provides the occupants with real-time data enabling them to monitor and control their own environments suited to their needs. Implementing IoT-enabled sensors and monitoring helps to create smarter, more energy-efficient environments, and enhanced building performance because it is convenient, time saving, and energy saving
  • Renewable energy systems improve the retaining of heat: Passive House windows including the frames can use triple-pane insulated glazing which are sealed with argon or filled with krypton gas. They have low-emissivity coatings, solar heat-gain coefficient, 'warm edge' insulating glass spacers, and thermal break window frames helping to retain heat. New technologies are being developed to help decarbonisation by creating carbon-neutral energy systems that can convert leftover energy from renewables and store them for an extended period for example heat batteries and home heating and off-grid cooking. Heat batteries can help to store heat for longer as they store and release thermal energy, taking up less room than a hot water tank. The company, Pumped Heat, is developing a heat storage unit by using renewable electrical energy. The generating of heat from electricity enables home heating and off-grid solar cooking helping to reduce carbon emissions and achieve net zero
  • Thermal Imagery guarantees maximum efficiency of solar thermal technology: solar thermal technology can generate energy for heating and cooling to provide Passive House buildings with hot water and heat. The heat can only be used in the building where it is installed. This helps to reduce the use of primary energy as less fuel is then needed for water heating. Thermal imaging can assess a buildings energy efficiency by reporting on things such as heat loss, the flow of heat, moisture, and help with keeping solar panels in good condition to ensure maximum efficiency. Thermal Imaging provides informative documentation and allows for energy efficiency improvements
  • New heating technology reduces greenhouse gasses: The National Housing Federation claims that decarbonising homes is “an essential part of tackling climate change”. The Passive House concept is important in terms of building for a greener future as it aims to reduce greenhouse gasses. With burning natural gas in our homes contributing to a third of UK carbon emissions, new central heating technology can help to reduce the emissions by switching from natural gas to hydrogen or implementing renewable heating systems such as solar thermal, biomass boilers, air source heat pumps, and ground source heat pumps.
