Trust the accredited green builders for energy-efficient housing in Melbourne

The government has set new standards for sustainable building, and new technologies and innovations are being rolled out every day. That is why it is essential to enlist the services of sustainability experts for energy-efficient homes in Melbourne.

Capital Building is an accredited Green Living Master Builder, so you can be sure they can help you create a plan for your project that will save money and energy while also improving the value of your home. Capital Building are also a member of Passive House Association, a voluntary standard for energy efficiency in building and facilitating low energy buildings that require low energy inputs to run.

Why should I choose energy-efficient home designs?

Energy efficiency is a significant factor in the cost of living, and energy-efficient homes are not only more comfortable to live with, but they also save you money on your monthly bills. The energy-saving benefits of low-energy houses also help reduce greenhouse gas emissions and protect our environment for future generations.

There are now also government regulations to be considered for all new home designs. For example, an essential requirement is to ensure that your new home meets the Australian Government’s National Construction Code (NCC). This code requires all new dwellings built after April 2009 to achieve six-star ratings in both summer and winter conditions.

Creating the most out of the space available

Careful planning on the location and orientation of key spaces in your new Melbourne home can help deliver significant efficiencies. Our team will look to make the most out of existing space before adding new ones, always looking to orientate living areas and indoor-outdoor areas to the north. We will also look to minimise west, east and south-facing windows without compromising ventilation so that you can effectively enjoy free heating during the winter months.

Achieving energy efficiency in your new Melbourne home doesn’t have to break the bank, either. The capital team will help you make the right choices for your energy-efficient housing design so that you get the benefits without breaking the bank. We have helped hundreds of families in Melbourne discover their perfect balance between comfort and cost savings with our unique approach to energy-efficient design.

Here are some of the ways our team of green builders in Melbourne will help you design and construct a sustainable, energy-efficient home without breaking your budget:

Our Friendly Team

The latest innovations in insulation

Insufficient or poorly installed insulation will result in your heating and cooling efforts escaping through your roof, walls, windows and floors. Correct ceiling insulation, as well as microporous building, wraps under tiles and foil blanket under steel roofing ensure the building envelope retains an even temperature, translating into lower heating inputs.

Roofing

Correct roof designs with a sufficient size cavity are vital. To keep the outside heat away, reflective foil should be installed between the rafters when retrofitting or on top of the rafters when re-roofing.

Flat roof designs are avoided as they are susceptible to leaks and moisture infiltration. Houses with no roof cavity are the hardest to insulate or ventilate effectively, so we will not construct your energy-efficient home using a flat or pitched roof without a cavity.

We also avoid skylights unless there is no other alternative, as while they are a great source of natural light, they also provide a portal for rapid heat gain and loss at the wrong times. For homeowners that specifically want skylights, we use the double glazed opening type to minimise the heat loss and gain.

Windows

All Capital home extensions are supplied with double glazed windows. Double glazed and well-sealed windows and doors have only recently started to become the choice of homeowners and builders, in Melbourne, largely due to the introduction of 6-star energy ratings in 2011. If a home does not have double glazing it can still perform close to or better than a double glazed home. Curtains and awnings will also greatly improve the performance of double-glazed units.

Our Credentials

Building an extension or renovating is one of the biggest purchases in our lifetime. Therefore, it is essential that before going ahead with a project you can trust the building company that you choose.

Capital Building has an impressive list of credentials which means that should you choose it, you will be using a trusted, experienced, honest and safe building operator.

Heating and cooling solutions

Did you know that heating and cooling can make up to half of your electricity bill? So, it is a vital area to focus on and Capital Building employs a range of strategies to reduce your heating and cooling expenses.

Blinds and shutters are a stylish way to avoid heat gain, and loss as up to 30 per cent of your heating and cooling can escape through your windows. Shading over your windows will also protect them from direct sun in the summer months that can rapidly heat your home. Capital also use double glazing on new works in tandem with blinds and other window coverings, usually selected and supplied by the owner.

There are several smart innovations that we can include, from old-school methods like reversible ceiling fans to automation like mechanical ventilation systems, including self-closing ducts and heat recovery systems.

Renewable energy generating electricity

Solar panels and Energy efficient lighting are the best way to reduce electricity expenses. With government rebates and cheaper systems, the payback for solar installations is now around 2 years.

Solar panels can also help reduce heat build up of the roof as they also provide shade.

Hot water, heating and cooking

It is vital to use all electric appliances to take full advantage of your solar system investment.

Electric ovens and hot plates. Reverse cycle air conditioning and heat pump hot water systems. Whilst some of these may cost a little more, after government rebates, they are better value than gas or conventional electric element type, in the long run.

Efficient lighting is also essential, and low watt LED options hare provided on all builds.

Recycling of building materials

Any building materials that can be recycled will be recycled. For example, for brick houses, try to recycle existing roof tiles, clay bricks and large timber beams. At the same time, Capital Building generally recommends recycled bricks and roof tiles to best match the existing materials. Most building waste is also recycled.

Water efficiency

Capital Building will also install rainwater tanks to supply toilets, laundry and garden water. Filters and mains re-direction pumps can be useful/cost-effective alternative in areas with no stormwater. Other solutions also available depending on individual circumstances.

Solar panels

Solar power has become increasingly good value for money, particularly for larger consumers of electricity such as businesses and large families. It has also curbed power companies ability to increase their prices too much. Every time they do they make solar more accessible. Solar panels have the added benefit of shading the roof.

Sustainable materials

Capital Buildings design process always considers and prefers:

Use locally produced materials as much as possible.
Use materials that require less energy to produce.
Use sustainable materials, i.e., plantation timber versus rainforest timbers.
Use thermally efficient materials.
Capitals project waste is recycled, and only about 30 per cent goes into landfill.

Amy B.

We worked with Capital for an extension of our single storey weatherboard house and they were great to work with from start to finish. Great communication with everyone in the team from design to handover and it’s clear that they care about doing a good job. We lived onsite throughout with our toddler and the whole crew were friendly and professional which made the process much easier. Highly recommend!

Pranita C.

We are delighted that we chose Capital for our extension project. Pierce, who was the first point of contact for us at Capital in the initial phases, was one of the main reasons for us to go with Capital. Pierce was very patient with us and made a lot of effort to understand and translate our requirements. They transformed our 2-bed villa into a 4-bed family house, not only by adding all that extra space but also by enhancing the appearance of our house to a modern, contemporary home. The process took approximately seven months (including Christmas break), which was very quick. We lived in the house while extending and had no trouble. The speed did not compromise the quality. All trades used were experienced and strived for perfection. Capital has a great team of people, well led by Travis. All our interactions with Capital team were professional and I would highly recommend Capital (CB) to anyone wanting to do an extension/transformation of their home.

Response from the owner: Thankyou for the review Pranita. We are thrilled you are enjoying your new extension and it was great working with you also. Best of luck for the future, CBC Team.

We had our 3 bedroom single storey 1950s house transformed into a 2 storey 4 bedroom house. When we bought our place it was the best we could afford, and once we outgrew it we tried looking for something bigger but the cost is prohibitive and you'd have to move to the outer suburbs to get something reasonably sized. We approached several builders, and they1. Didn't even bother turning up,2. Demanded a $1000 payment for plans without even looking at the house3. Turned up, looked at us, and basically told us we couldn't afford it.Enter Dean from Capital Building. Over several meetings, he patiently and professionally visited our place, listened to our wants, offered us options, and generally gave us the feeling that we had a way forward. We would like to thank Dean for his enthusiasm and the confidence he gave us to go ahead with this exercise.Once permits were in place, we were handed over to the build team, and again, we were put at ease with their approachability and professionalism.We have never built before, so all this was new to us. The team at Capital was very good at explaining the processes and addressing our concerns. Travis, as the director, is a good operator and very switched on. Laura, our designer, helped us a lot with her input for the materials and components of the build. Tiffany kept us in the loop with constant communication regarding dates and activities.Andrew was the supervisor assigned to our build and was in charge of the team doing the work on our house. We want to thank him for his patience and the way he tried his best to make this process as smooth as possible.Make no mistake, a build of this nature is not a walk in the park. It is significant work and to live through it as we did with our young family can be challenging. However, Capital and their team genuinely did their best to make it as low impact on us as possible and 7 months later we basically have a brand new house. We still can't believe it sometimes.Thank you to the team at Capital. With the housing market being what it is, I think extensions like these are a great affordable option for families who grow out of their homes but want to stay in the suburbs where they've put down roots. Capital's 5 star reviews and growth are no accident. They are good at what they do and great to work with.We wholeheartedly recommend them.

Response from the owner: Fantastic Dinesh, We are really glad you are enjoying the space and your review perfectly sums up our process and what we try to achieve. We agree, extensions are a quick and cost affective way to increase your space. Thanks again CBC Team.
