Why

We spend 90% or more of our time indoors. Smart Plus Homes believes that everyone deserves to live and work in a healthy and comfortable indoor environment which is energy efficient and sustainable. As we all are entitled to such a home/workplace, we need to be resourceful and smart about it.

How

By creating a highly efficient outer shell of a building, its energy consumption will drastically reduce and the lifetime of the structure will increase significantly. At the same time, the life quality for occupants is becoming more enhanced.

What

Smart Plus Homes helps professionals and future home owners to create healthy and comfortable homes and buildings that are energy efficient and sustainable. We do this through Education, Consultancy and Design and provide the knowledge required to ‘connect the dots’ and understand the importance of energy efficient designs for comfort and health.

Design

We offer smart home designs that are planned to your needs and to the environment you are building in. All designs consider your health, comfort, energy efficiency and sustainability. We can work with you as a client directly or with your architect, designer or builder.

Consultation

You may have a project and want to consider health, comfort, energy efficiency or sustainability. You may need thermal imaging, blower door testing or a Passive House calculation. You may have questions like: “Is Passive House feasible?” or “Do I need triple glazing?”, we can help you with making the right choices.

Products

Smart Plus Homes realised that a lot of products are not widely available in Australia. You are looking for Heat Recovery Ventilation systems (HRV), Air tightness products, quality windows or other solutions? We will make it easier to find the best product solutions.

Education

Healthy and comfortable buildings that are energy efficient and sustainable are becoming more and more a standard. Smart Plus Homes offers presentations, courses and training in this evolutionary area in the building industry. You can book Smart Plus Homes for events and internal training or attend the events organised by Smart Plus Homes.

What is a Passive House?

Passive House is more than just a low-energy building. It is a building standard that provides healthy and comfortable living space whilst at the same time being energy efficient and sustainable. The good thing is that it can be quite affordable.

The concept is straight forward; by creating a highly efficient outer shell of a building, the energy consumption of that building will be drastically reduced during the time of use. Another positive effect is that, the lifetime of the structure will increase significantly. At the same time, the life quality for the occupants is getting enhanced. Passive House is a concept that can be applied by anyone and to any building project. It is a proven concept, formulated in a flexible and simple energy modelling tool called PHPP. Smart Plus Homes believes that the PHPP is a calculation that should be mandatory to all building projects that create a conditioned space; the same as engineering is required for every structure build.  

There are 5 key components
of a Passive House

Thermal Insulation

Thermal Insulation reduces the heat transport. In the cold season, the Thermal Insulation keeps the heat in the building, and in the hot season, the thermal insulation keeps the heat out of the building. In most cases, the thermal insulation is the trapped air in a poorly conducting material. Typically used materials are fibres and foams. These materials can only perform effectively if there is no air movement in the material.

Absence of Thermal Bridges

 

Thermal bridges can considerably increase the transmission heat losses through the outer thermal shell of a building (building envelope), which increases heating demands in winter and cooling demand in summer. A Thermal Bridge is a spot in the thermal envelope, where an inconsistency is present. An irregularity could be a change of geometry like a building corner or a material change like a metal fixing.

Airtightness of the building

The Thermal Insulation can only perform at its best if no air movement is present, most easily demonstrated by a woolly sweater and a windbreaker jacket. On a cold windy day, wearing a woolly sweater or a windproof jacket does not keep a person warm. However, if the windbreaker is worn over the sweater, a person stays warm. This improvement of the thermal insulation (woolly sweater) by using an airtightness system (windproof jacket) is the positive effect of airtightness in conjunction with thermal insulation.

Passive House Windows

Transparent materials like glass let the short-wave radiation from the sun (sunlight) through, but the long wave radiation (heat) is absorbed and then passed on. In double glazed windows, the trapped gas between the layers of glass is the thermal insulator. In this case, the energy can enter the building as sunlight, but the energy cannot leave the building as heat. A Passive House uses this principle in a cold climate. In a hot climate, this effect is not wanted because it leads to overheating of the building. Shades or low thermal emissivity coatings are needed in a hot climate.

Ventilation Heat Recovery

Efficient heat recovery ventilation is the key for a good indoor air quality and energy saving. By supplying fresh air to areas like bedrooms and living rooms, and extracting from the wet areas like the bathroom, kitchen and laundry 24/7, indoor air quality stays high. The energy demand is minimal, and the heat recovery can recover up to 95%. For example, if you have 20⁰C inside the building and you have 40⁰C outside, the supplied air can be cool as 22⁰C without using a cooling system. If you have 22⁰C inside and you have 2⁰C outside, the supplied air can be as warm as 20⁰C without using a heating system.
