Steps That Passive House Builders Take to Come Up With a Finished Home

Installing a passive house may be a bit expensive, but in the long run, it is highly beneficial to live in a passive home. It is a way of healthy living. To build a passive home, you need a team of professional builders with years of experience in making this technology a traditional way of living. Planning and infrastructure of a passive house depend on a lot of things.

There are multiple steps that you need to follow while making a passive home.

Step 1. Panning

For a passive home building, the mechanism of installing an insulation technique is the most essential. Architects imply new house making science to design a passive home. They collaborate with the builders and incorporate planning and structuring of the house. The architects need to plan the right way of installing thermal insulation and airtight construction for your passive home.

Step 2. Location of the house:

Passive home builders near Melbourne first find the right spot for enacting the designing. The site must have accurate solar access to optimise the sun’s warm light in winter, and on the contrary, for the summertime, the minimisation of solar access is equally important. Builders look for the right positioning of landscaping and plantation that will give keep your house cool in summer.

Step 3. Insulation:

Insulating the home in the right way is the most valuable step of passive home building. Thermal insulation ensures reducing the temperature of the house. The natural sunlight is intact inside the house through this technique. There is no need to install centrally backed up heater in your house. Not even you will need an air conditioner for the summertime. Thus it is a great way to cut the energy costing in your home.

Step 4. Window and door sealing:

The installation of windows and doors for a passive home is not traditional. You must install high-performance energy-efficient doors and windows to make the space airtight. The seal of windows and doors decide the level of insulation inside the home. In the summertime, the windows will be down during the daytime, and in winter the rule is to get the maximum heat and restore it for the night.  To check on the capacity of holding the air a high-quality door and window test is included using pressurisation and depressurisation.

Step 5 Air testing through Heat Recovery Ventilator

Heat recovery ventilator installation is beneficial because of its mechanism of letting in fresh outdoor air and passing the stale warm air or pollutants from indoor.

Conclusion:

So, these are the steps contactors and homebuilders are following to structure a passive home. In the home building industry, this new pattern is trending. Professional architects and housebuilders work in collaboration to build one passive home.

Things to Know before you Invest on Passive House Supplies

Are you thinking of living in an energy efficient home? Well! You are not alone! There is a good number of people shifting to passive building routes and the best part is that they are independently embarking on such projects without help from builders unless they don’t have a choice. Although a lot of layouts are already there on the internet, it’s usual for you to consider a design which will specifically go along with your lifestyle or family needs. Among several less energy intensive building theories that have been doing rounds across the world, Passive Housing is considered most efficient in terms of eco-friendliness. 

The decision of investing in Passive building cannot occur overnight and should not also be considered on a lighter note. A lot of building projects are nowadays raised based on passive building theories. Furthermore, it’s considered as a leading housing standard based on energy efficiency. Get some ideas on passive building through insights mentioned below: 

An easy-peasy layout 

A lot of you think that passive building isn’t as easy as it may appear, but believe it or not, it’s a lot less challenging, hassle-free and less time consuming. Considering that you will go on for a Self-Build approach, its commonplace for you to get hit by challenges. No worries! It’s same as when you were asked to do some origami by your school teacher. For kids such craftsmanship will appear demanding at first until the time they get a hang of it. 

Since you have decided to go about with the project on your own, it’s more likely you will want it to last for a lifetime and hence will be aiming for High Performance Building Supplies. This is supposedly one of the most effective ways to future-proof your home. Over and again it has been proved that passive building exceeds conventional structures in terms of performance related to thermal efficiency, air-tightness, and energy and load requirements. 

Site 

Since you have decided to build yourself a Passive Home, it’s most important you consider the site. For passive building, sites play an important role since the structures should have enough access to solar rays. Yes! Solar gains should be considerably high when you are choosing passive housing. Hence it is ideal to choose a site to the south which is supposed to receive maximum sunrays and air. A south facing home receives maximum energy. Also, consider the landscape, the neighbouring buildings and the trees before you bet on a site. 

Design 

Other than paying your attention on Passive House Supplies, give yourself some time to select a design that will help you gain maximum out of solar energy and in terms of performance. There are simple to complex designs available on the internet but make sure the house is south oriented to welcome in more sunrays and is based on a compact design to trap in more natural energy. Thermal performance and air-tightness are primary concerns when it comes to choosing designs for passive building. Also as you work on the layout, make sure you group in the wet areas altogether to ensure saving on plumbing costs and energy. 

Meanwhile, you must get in touch with a team inclusive of professionals who will be able to make valuable recommendations and help you build a certified structure while lending you a hand on the job. 

Ventilation in Passive House during the times of COVID 19 – A Brief Discussion

The Ventilation System or the Mechanical Ventilation with Heat Recovery (MVHR) of the passive house generally draws fresh air from the atmosphere and pushes them into the rooms. During this epidemic triggered off by the COVID 19 people are permitted to move around in the open as long as they maintain social distancing as prescribed by the experts. Indeed, like all the other viruses that are exhaled by the infected people are diluted strongly. Hence, the concentration of viruses in the atmosphere is low enough to turn harmless. So the bottom line is that, COVID 19 is not airborne and even if it is airborne it cannot stay in the air long enough to be a genuine threat.

The Ventilation issue of Passive House

The pandemic condition that is prevailing at this point shows pretty vividly why the passive house builders in Melbourne as well as the experts are putting more emphasis on the ventilation of the passive houses and buildings with the fresh air outside. They have also clearly mentioned why it is highly dangerous to use recirculated air ventilation.

Here is a quick look!

The air outside may be polluted, but it will only and only be polluted by dust, which can anyway be filtered by the high-quality fine-class filters like F7..F9, which are recommended by the passive house specialists and are as such, installed at the external air ducts. In fact, only recently, a statement that was published by the German Society of Ventilation (FKG) clearly stated that the passive house ventilation systems (MVHR) that are operating with the atmospheric air should be kept operating and should never be switched off. They also warned against the dangers of reducing or switching off the outside airflow.

To ascertain the gravity of their warning, it is essential to compare the ventilation system of the passive houses in Melbourne with that of the conventional buildings, which do not have any controlled ventilation system. They have clearly stated that all the conventional buildings without these controlled ventilation systems MUST have all their rooms properly ventilated with the atmospheric air. Rooms with a ventilation system that have no connection with the atmospheric air, like in AC rooms, trains, buses, and cars are highly dangerous zones and people using them are more prone to get infected by COVID 19 than those who are not.

The experts are of the opinion that the spaces with conditioned atmosphere might get virally contaminated and this can pose a real danger when the air accumulates into the interior spaces inhabited by users. In passive houses, with high tech filters properly installed at strategic entry points of the air, the intake air is even cleaner. That is the reason, the passive house experts in Melbourne like any other place will recommend proper operation of the outdoor air ventilation mechanism, even during the COVID 19 Pandemic. 

Reasons Why You Need Windows in Passive Houses That Can Open

As passive houses are still not the most trending thing in the modern world (there are no reasons why they shouldn’t be) and an idea that is somewhat obscured by myths and legends, people hesitate to opt for passive houses. They can’t only imagine how a whole house can literally be off the power grid. Among the myths that are circulated regarding passive houses, one of the most outrageous is that you can’t open a window in passive houses. While that is a lie, it’s necessary to have windows in a home that can be opened for a variety of reasons. Here are some of the reasons why it’s crucial to have proper air circulation in a house, passive or otherwise. 

An Energy-efficient Way of Cooling Your Building

During the summer, keeping your windows open is one of the cheapest, easiest and most environment-friendly way of cooling your energy-efficient home. If you have windows on opposite sides of the building, it allows for cross ventilation. In other words, the windows let natural breeze to pass through the building, reducing heat. It is the most effective solution in coastal and tropical areas where the temperature is more relaxed at night than during the day. 

Better than Passive House Air Ducts

The passive house ventilation process generally provides lower air exchange than cross ventilation. The fan would disperse additional heat into the environment, and the cooling system is further weakened in the process. The air exchange ratios of air ducts installed in these buildings are not enough to prevent the air from being too humid or too dry during excessively hot (and cold) weather. Advanced air ventilation systems may be able to do the job, but they are more costly and less energy-efficient than the conventional ventilation systems. On the other hand, windows provide you with a natural solution for cooling your building. 

A Link to the World outside Your Four-Walls

Windows connect our house interior to the vast world of nature that is lying outside. They allow us to look at the breath-taking views of the sunset, hear the birds chirping and singing, and to call out to the children playing in the garden. That is why most homeowners while designing their houses, take care of the fact that it has broad and airy windows. They also want to be able to control when and how to open them.

If you are planning to design and build a passive house to promise your kids a better future, you could contact experienced and renowned passive house builders in Melbourne who will be able to take care of the whole project from scratch. Invest in a passive home and invest in a better tomorrow. 

Cut-Down Your Energy Use With Smart Lights- A Discussion!

Smart home lighting is always an important aspect of your oh-so energy-efficient homes. Other than brightening your property; they also improve home security, creates a good atmosphere and helps you cut down on your monthly bill.

And since; your home lighting accounts for approximately 6-8% of your home’s energy consumption; it does make sense to invest in quality energy-saving lights to turn your interior space into a pleasing and inviting one.

Digging Deeper Into Smart Lights For Your Energy-Efficient Home:-

Nowadays, the rise of smart home bulbs makes it possible for homeowners to control their lighting needs and in the process lessen its energy consumption. You can opt for smart bulbs to regulate your individual light needs.

However, as per energy-efficient home builders in Melbourne:-

“This may not be the best option for those wanting to integrate energy-conserving smart lights along with smart home assistance. Fortunately; for you; there are so many other alternatives that you can go for.”

Optimal options may include in the form of light dimmers, energy-saving lights along with a quality home energy management system much like a constellation connect. This helps reduce their home’s energy use and amp up their overall property protection.

As per their viewpoints; here are some smart lighting solutions to reduce your monthly electricity use.

Employing Smart Lighting Switches:-

They are a smart mode of regulating your home’s lighting and conserving energy consumption. As they are installed; you will be able to control one hard-wired energy-saving light switch- be it from your smart hub or smartphone. These smart lights can also be voice-controlled.

Some options which you can opt include:-

• Single Pole Smart Switch
• Three/Four-Way Smart Switch
• Plug-in Smart Switch

Setting Up Motion Sensors Whenever Applicable In Your House:-

Most motion sensor lighting help save energy by automatically switching off when it detects no activity in a particular room. You can even set it to trigger the lights only when there is a human activity (so as to prevent your cat’s from switching them on as she moves around your residence)

Where Can You Put Motion Sensors Inside Your Home

Motion sensors present the most energy-saving convenience to homeowners (as explained above). Some of those common areas where you can think of installing them include:-

• Basement
• Entryways
• Garages
• Closets
• Bathroom, kitchen
• Outside the main gate
• Hallways
• Children’s rooms

And other high traffic areas in your house.

Adding Smart Light Dimmers :-

In terms of smart lighting options; you can choose from the following:-

• CFLs:- Compact fluorescent light bulbs are extremely energy-efficient. But not being specifically designed for dimmer switches, and when used, they may flicker and have a shortened lifespan.

• LEDs:- They are presently the best lighting option for smart, energy efficient homes. They also last a long time and is compatible with LED dimmer switches.

• Halogen Bulbs:- When used with dimmer switches, they tend to use 20% less energy, in comparison to when they are not dimmed. But these bulbs may not always be appropriate for all homes.

For large spaces, halogen bulbs may prove less energy efficient, and that negates the benefit of using dimmer switches. If you have a large space, then you can opt for a standard low-wattage bulb.

And, Including Smart Energy-Efficient Timers :-

These energy-saving timers are usually placed between the plug and wall outlet. And they are fitted to turn off the plugged-in home item at any particular time.

They are also referred to as timer switches, smart energy-efficient timers and they come with multiple usages. These timers help turn on your home lights at predetermined moments, right before you enter your home after work.

Energy-Efficient Timers Are Mainly Used To Regulate

• Hot tubs and pool filters
• Outdoor security lights
• Small appliances (like for instance computer, radios, flatirons, etc.)
• Water heating appliances
• Indoor lighting

Now that you have a clear perspective on smart energy-efficient home lighting solutions, be sure to discuss these with your home builder about these installations.

Also make it a point to always procure high performance building supplies in Melbourne for your dream home construction. You can even consult with your chosen builder to decide which option will work best for your specific requirements.

How The Design Of An Energy Efficient Functions?

When things come down to discussing the designs of energy-efficient homes, there a number of intricate issues involved. In fact, when we speak about the efficacy or the energy efficiency of these homes, it revolves around the successful coordination of some fundamental elements. All these elements work in close sync with each other to return the desired end effect of a passive house.

Here on this page, we discuss some of these elements, around which the functionality of each energy-efficient home involves.

Proper Orientation of the Windows:

In the typical energy-efficient house, windows or other inlets & devices that collect solar energy, generally face 30 degrees true south and should remain shaded for avoiding overheating during the summers.

During the fall, spring and the winter months, however, they should not ideally remain shaded. This will keep the right balance of heating and cooling effects during the entire season.

Thermal Mass:

Thermal Mass in a passive home generally includes the concrete, stone, bricks, tiles and the likes, which absorb heat from the outside world during the summer days, keeping the interiors cool, and retains the warm air in the house, helping the interiors to remain warm and cozy during the winters.

Other thermal masses in passive solar homes include water and the phase change products. These masses are extremely efficient in storing heat. In the well-insulated homes that are located in a moderate or extreme climate, the thermal mass created by the furnishings and of course, the drywalls of the home is more than sufficient.

This will help in the elimination of the very need for additional thermal storage materials, thus increasing the energy efficiency by manifolds.

Mechanisms of Distributions

Solar heat is transferred from its collection points, and are stored in various vantage points of the house, through the process of conduction, radiation and convection.

In certain smaller homes, small blowers and fans are engaged for able distribution of the heat. Conduction takes place as and when and strategically placed roof overhangs generate shades to vertical south windows during the summers.

Other control approaches that add to the energy efficiency includes various types of electronic sensing devices like a thermostat, various kinds of operable vents and dampers, which allow as well as restrict heat flow, low-emissivity blinds, awnings and operable insulation shutters.

Heat is transmitted through a medium like air as it moves from warmer to colder areas, and then all over the home.

Control Strategies

Appropriately sized and strategically placed roof overhangs generate shades to vertical south windows during the summers. Other control approaches that add to the energy efficiency includes various types of electronic sensing devices like a thermostat, multiple types of operable vents and dampers, which allow as well as restrict heat flow, low-emissivity blinds, awnings and operable insulation shutters.

So you see, passive house builders Melbourne use all these techniques and strategies to make the very mechanism of a passive house function. 

A Few Handy Plans that Passive House Builders Adopt

Expert passive house builders take an altogether different approach to come up with energy-efficient homes. Now the approach surely changes from one project to another depending upon the budget and the layout of the plan. Still, the principle upon which the plans are based remains more or less the same.
Now the main motive behind planning such homes remains constant – that is making sure that the home consumes as little energy as possible. How the experts achieve that through planning? Here are a few examples.

Dealing with the Facet in a special way

When it comes to designing the facet, the passive house builders in Melbourne will make sure that it faces the western sun instead of the eastern one. In other words, it will be the setting sun or a much feebler sun that the facet will be facing. Thus, they can minimise the extent of sunlight getting inside the building, thereby helping the interiors to remain cooler.

Setting up brick volumes on the ground floor 

Setting up multiple brick volumes at strategic locations of the ground floor will create enough shades, which will again make the interiors cooler. It does so by obstructing the unabated flow of sunlight chronologically. When that happens, the interior by default will create a much cooler ambience, which will reduce the need for artificial cooling significantly.

Setting up a connection with the backyard lawn

One noble idea is giving the space more scope to facilitate air circulation, which makes the interiors cooler and healthier. This is done by setting up multiple sets of large sliding doors on either side of the dining area on the ground floor (these buildings usually follow the rule of reverse living. They get directly connect the interiors to the backyard lawn, thus facilitating freer flow of air in and out of the room. This naturally makes the interior airier and more energy efficient.

Setting up polished concrete surfaces and internal brick walls

At times, the makers of energy-efficient homes would cover the internal brick walls with polished concrete surfaces. This concrete surface provides that thermal mass, which keeps the interiors cool and comfortable even in the height of Aussie summers.

Setting up white walls and fit-outs 

Alternatively, they would set up white walls and back them with white fit-outs, which will give the home enough light and summery atmosphere during the winters, making the room warmer than what they would have been, otherwise. Again, these rooms generally have windows with tinted glass, which when closed during summer, makes the rooms cooler. So you see, it helps both ways in two different seasons.
Thus, the experts in most of the cases would put into effect passive solar design mechanisms, and this allows the building to optimise its thermal efficiency at the end of the day.
