How much land is required to contract a Halodome?
Halodome with the 12m/ 40f diameter has a footprint of approximately 100m2/ 1000sf however local building codes and set backs along with the customers aspirations are likely to determine the minimum land area required.
How do I know if my land is appropriate?
Generally, Halodome can be situated anywhere, if the off-site constructed platform option is employed however a detailed review of site, is required before confirmation.
Does the land require sewage, electrics, plumbing & water accessibility?
Halodome does not provide any of these services, mains services and off grid options are supplied by the client.
Is the Halodome suited to cold and hot climates?
The Passivehaus version of Halodome is ideally suited to temperate or cold areas, if located in hot humid climates additional cooling support will likely be required.
What is the main difference between Passive & Non-passive?
Halodome Passivehaus has a certified airtightness standard and a ventilation system to replenish fresh air with an Energy Recovery Unit to ensure minimal loss of ambient internal temperature. Insulation levels are higher and doors and windows are triple glazed low E glazing.
Halodome standard has similar levels of air tightness and insulation but no ventilation system, an energy recovery unit and uses double glazing, also of a very high standard.
What are the heating or cooling solutions for Non-passive?
Halodome can use any market standard heating options. The dome shape enables the temperature to adjust very quickly.
How many sizes are available and are they adjustable?
9m/ 30f or 12m/ 40f diameter Halodomes are available.
What are the finish options for the interior and exterior?
We offer a reclaimed timber internal linings and two alternatives for the exterior cladding; Canadian cedar shingle or different coloured stainless steel options.
Are ceiling heights adjustable?
Is there an option of a covered hallway to connect 2 Halodomes if I wanted to combine and create a larger living space?
Yes there is. Previous construction projects have added walkways and even conventional extensions to form kitchens and bathrooms. These options are not supplied by Halodome.
Is there an option for a completely closed off second level?
Yes, this can be done but is not supplied by Halodome.
Is electrical wiring covered and hidden within the walls?
The electrical wiring runs in conduits between the panels and can be accessed by removing part of the internal lining. Making it possible to install ceiling lighting, sound system, fans and power sockets where desired.
Is there an option of skylights?
Additional roof light windows can be fitted and are in effect skylights.
Are plans available to show best and varied use of space internally?
We have examples and plans showing various layout options, please email the To Studio team to request options.
Where do the materials come from?
Halodomes are almost entirely constructed from timber. The structural panel frames use PEFC certified timber sourced from Finland. The non-structural elements are produced from reclaimed timber that comes from a number of different international PEFC sources. A Passivhaus building is required to use approved suppliers only for the key components such as windows, doors, and ERU (energy recovery unit and mechanical ventilation system).
Are the Halodome materials resistant to terminates and other bugs?
Yes, all timber elements are treated with high pressure LOSP technology. The Halodome raised platform option also allows for easy visual inspection of termites and other pests.
From the time of purchase, what is the kit production time?
Normally 20 weeks from receipt of the first stage payment to loading.
What pre-preparation and foundation/platform are required before construction can begin?
The client will prepare all local planning/ building consent, access and site prepartions including a concrete foundation slab or footings piers if Haldome floor platform is selected. Halodome can supply minimum requirements for the conventional concrete foundation slab and pier configuration however, both will need local certification by the appropriate consultants and authorities.
What can I expect at the delivery?
Halodome is delivered as a full kit of pre-assembled panels and components, including the floor platform if required, to your site in shipping containers. Noting that the most complex parts of the construction are completed in our workshops.
Who is responsible for the construction?
The client is responsible for assembling the Halodome’s 80 or 45 panels along with the roofing system and internal linings that form the Halodome you’ve selected. A designated local architect and/ or contractor can select to request support from a Halodome specialist representative who will visit the site and provide advice for a set period and agreed time.
Will construction instructions be provided?
A detailed fully comprehensive instruction manual is provided with the components on delivery.
What are the build steps & how long does it take?
- Preparing the flooring base(before Halodome arrival)
- Installation of the 80 or 45 pre-finished panels – up to 1 week
- Fixing of the roofing battens – up to 5 days
- Fitting window and door flashings –up to 5 days
- Fitting roof shingles or tiles - 2/3 weeks
- Tape sealing the internal membrane – 2/3 days
- Assembling the mezzanine (if included) – which can be installed concurrently with the roof system.
- Fitting the internal linings – 1 week
The Dome Home onsite construction can be finished in under 6 weeks if given sufficient manpower.
What happens in the event of damage when the Halodome components arrive damaged?
We will repair on arrival and if this is not possible, replace the relevant component.
After Dome Home installation, what additional support is available?
Interior design, Styling & Furnishings can be provided upon request.
What are the benefits of Passivehaus construction?
Passivhaus certification focuses on energy efficiency of the building itself, specifically:
- Excellent insulation with the heating/cooling energy demand limited to 15KWh/M2/year.
- Optimised connection details that avoid thermal bridging.
- An airtight building envelope which eliminates draughts and reduces energy consumption.
- A controlled ventilation system with high quality filters, an efficient energy recovery system and low energy usage.
- Total energy demand of < 120KWh/M2/year.
- Heating/cooling energy demand limited to 15KWh/M2/year.
Does opening door or windows effect “PASSIVE” performance?
A Passivhaus is designed with a mechanical ventilation system and Energy Recovery Unit. Opening doors and window for ventilation will effect passive house performance and therefore you may require additional energy to the heat or cool the building.
What type of LEED or energy-efficiency certification (aside from German-Passive House standards) would the building be able to obtain.
The Halodome is capable of satisfing and exceeding the LEED requirements (or any others) where it applies to the building itself but the customer is required to consider areas such as: a sustainable site, water efficiency and renewables if they want to achieve the highest level of LEED certification for the overall project.
Leadership in Energy and Environmental Design (LEED) is a rating system devised by the United States Green Building Council (USGBC) to evaluate the environmental performance of a building and encourage market transformation towards sustainable design. . The LEED rating system offers four certification levels for new construction, Certified, Silver, Gold and Platinum, that correspond to the number of credits accrued in 6 green design categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality.
Therefore LEED is simply a point system, or a scorecard. The more energy efficient and "green" the building is, the more points it will earn. These points are earned through meeting credit requirements in LEED in the following categories:
1. Sustainable Sites (SS)
Site Selection is the first step and arguably the most important part of the green building process. It’s simple, the potential environmental effects of the project, depends on where you plan to build it. LEED awards the location you've chosen based on items ranging from proximity to public Transit to bike storage and showers.
2. Water Efficiency (WE)
Water, like any other resource is finite. As the global population increases, so does the demand for water to be used in human and industrial processes. LEED awards the reduction of water used in toilets as well as the Re-use of grey water.
3. Energy and Atmosphere (EA)
Most credits in ALL LEED categories are aimed to indirectly reduce the need for electricity. EA is the one category whose purpose is to directly reduce energy demand. The LEED rating system rewards buildings for reducing their energy demand, increasing their energy efficiency, monitoring energy use as well as investing in Renewable energy sources.
4. Materials and Resources (MR)
MR deals with two items, reducing waste which is sent to landfills and Reducing the environmental impact of a building's materials. LEED looks at how Materials are: Selected, Disposed and Reduced. Points are awarded for materials reuse, recyclying, renewable materials and maintaining a building already on the proposed site.
5. Indoor Environmental Quality (IEQ)
IEQ is a large section in LEED and addresses the environment INSIDE a building and how it affects the occupants inside. IEQ awards points for lighting, temperature, ventilation, indoor pollution and the amount of Daylight.
6. Innovation in Design (ID)
This section of LEED awards points for inventive, sustainable and green building strategies which are beyond the scope of the LEED Rating System and not properly rewarded. There is a maximum of 6 points and having a LEED AP on the project is worth 1 POINT!
How safe is the Halodome certification. Does it meet US regulations?
Halodome has a structural design certification that is valid in all counties except USA and Canada. We are in contact with structural engineers in California to understand the regulartory process and then to evaluate our design against the local codes. We may have to repeat this process in certain states or extreme locations however, it’s thought that the Californian certification will be good enough for the majority of states.
Is the Halodome resilient to earthquake prone regions?
The Halodome is an inherently stable structure and has been certified in the Philippines which is a high risk area. We are looking to obtain a general certification for California, specific high risk areas may require additional approvals.
Are all Halodomes certified for earthquake conditions or was this a special case?
The Palawan Halodome was modified to further strengthen the structure to ensure it met certification requests related to earthquakes. This is not necessary for most locations. Each project is assessed individually to identify any geographic or climatic issues and if any requirement for further structural reinforcement is required.
Does Halodome come with a warranty?
We supply a structural material warranty of 10 years.
Where can I obtain prices?
As pricing is subject to client requirements, please complete the online questionnaire to qualify for pricing information.
Is construction/ assembly inclusive of the price?
Construction is not inclusive of the price and clients are required to hire local architects/ contractors to install their Halodome.
In a few select regions we can recommend architects/ contractors, however it is the responsibility of the client to allocate a reputable representatives to manage the project to completion.
Does the price of the Halodome cover import duties?
No, import duty will vary from country to county eg. UK VAT.
