Lighting

LIGHTING

To convert the light level to a specific power, there is a basic rule: 2/3 W/m² per 100 lux.

Example:

We take the example of an office of 20m ² where 5 fluorescent tubes 36W lamps are hanging. Fluorescent tubes are relatively efficient and give about 80 lm/W off. In addition, we let the electrical ballast out of consideration. The amount of light (lm) of the lights coming is then 5 x 36 W x 80 lm / W = 14,400 lm. Furthermore, we assume an efficiency of 80% for the fixture and an efficiency of 70% for the room. The illuminance on the floor is 80% x 70% x 14,400 / 20 sqm. = 400 lm / m² or 400 lux.

In addition to the choice of the 36 Watt, we have some alternatives with 2 x 36 Watt, 1 x 58 Watt or 2 x 58 Watt.

1. Spaces where 200-300 lux per m² is required:

- Storage spaces

- Archives

- Industrial buildings

- Workplaces

2. Spaces where 450-500 lux per m² is required:

- Office

- Fitness

- Gym

- Showroom

- Classrooms

- Kindergarten

- Retail spaces

- Entrance / corridor / waiting room

3. Spaces where 800-1000 lux per m² is required:

- Optician

- Laboratory

- Dentist

- Kitchen

Electrical boiler

ECTRICAL BOILER

For the installation of a hot water facility we offer various options, like:

- Electrical boiler 10 Liters

- Electrical boiler 30 Liters

- Electrical boiler 50 Liters

- Electrical boiler 80 liters

Determining capacity needed:

With the following base rule you can determine the capacity.

Taking a bath: 120 liters for comfortable use - 170 liters for a combination tub and shower

Taking a shower: 40 liters for comfortable use - 70 liters for a long shower and rainshowers

Washbasin: Between seven to ten liters per use

WARNING: To calculate the available amount of water, the contents of the tank should be doubled by a factor of 2 to 2,5. This is because you’re using hot water mixed with cold water also while showering in order to have a pleasant 37 degrees. For 200 liters of hot water you therefore need a boiler capacity of 80 liters.

Warm up time boiler:

To determine the heating time of the boiler, below you will find a sample calculation.

1 Joule = 1 W/s [Watt per second]
You need 6270 kW / sec.

We now suppose that the power of your water heater is 10 KW (so in 1 second it delivers 10,000 joules), then it takes:

6270 / 10 = 627 sec. [ = 10,45 min]

For a standard water heater, for example of 10 liters / 3 kW, you will lead to a warm-up time of 34.8 minutes. The fast water heater of 10 liters that we use has a power output of 2200 watts. Warm-up time: 22 minutes!

Kitchen block

KITCHEN BLOCK (PANTRY)

The kitchen block (also called pantry) consists of two cupboards and a workplace made of stainless steel. This is a material with many possibilities, especially when used as workplace. Stainless steel is an alloy, obtained by melting and mixing different metals. The main elements in the alloy are chromium and nickel.

Maintenance workplace in stainless steel:

The pollution must be washed of with plenty of water and a degreasing soft soap. Cutting boards are a must when using a stainless steel worktop, because scratches are immediately visible. However, the scratches affect only the appearance, not the durability of the stainless steel worktop.

Advantages of a workplace made of stainless steel:

Waterproof
Heat-resistent
Hygienic

Durable

The kitchen block is equipped with a tap, excluding boiler.

Building permit

With our unit configurator you can easily realize your accommodation online. After entering the desired outer dimensions and the required inside height you have established the basis for your tailored (semi)permanent housing solution.

To inform you in the best possible way, we have added some further information in our configurator which might help you in your choices regarding, for example, the lighting, the standards for workplaces and the laying of the foundation. Below you will find specific information about the necessity of applying for a building permit.

BUILDING PERMIT

Who used to go building in the past, needed several permits, such as a building permit, a demolition permit and an environmental permit. The application process has been made easier and the licenses have been merged into one permit: the environmental permit.

ATTENTION: a building permit is not always necessary. A dormer window, a skylight, an outbuilding, a satellite dish or a yard/garden fence can usually be build without a permit. However, this rule does not apply to monuments and buildings in the conservation area. On following link you will find specific information about the rules for a building permit in the UK: https://www.gov.uk/building-regulations-approval

If you are unsure whether you can start the building project unlicensed, we suggest you to seek advice from the Public Affairs Department at the town hall. In this way, you will avoid problems later.

Yet to submit an application for a building permit?

You want to create a temporary building for a certain period. For that purpose, broadly two regulations apply, which will be used as well as a basis for this task:

- General Provisions Environmental Law / Environmental Permit

- Decree 2012

Law on Spatial Planning, Article 3.22; temporary exemption

With article 3.22 (Law on Spatial Planning) exemption from the provisions of a plan may be granted for a limited period. This is a socalled “outside the plan” exemption. The maximum period for which an exemption can be given is 5 years. After this period, it is obligatory to bring the anomaly either back in its original state or in agreement with the current zoning scheme.

ATTENTION: it must be a temporary need. When granting an exemption for a certain period, a procedure should be conducted. The intention to give an exemption must be explained. Views against this intention can be made by anyone.

Decree 2012, Article 1.14; Temporary construction

On building a temporaty structure, the terms in chapters 2 – 6 apply for an existing building, unless otherwise indicated in the department relevant for a certain description. In this statement we have based ourselves on the minimum requirements of a building permit.

Request authorization, what is needed?

The documents required to apply for an environmental permit, including:

- Map / elevations drawing

- Situation Drawing (ACAD file should be commissioned by the client)

Any necessary foundation calculations, have to be provided by third parties. These are not included.
Structural calculations, if required, have to be provided by Tribute Space. These are not included.
Any required harvesting and / or timber licenses, have to be provided by third parties. These are not included.
Any necessary excavation permits, have to be provided by third parties. These are not included.
Any other kinds of legal charges are not included.
The request of the necessary permits for the work location have to be done by the client and are the client’s responsibility.

WARNING: These rules are applicable in the Netherlands. For the English regulations, we advise you to contact your municipality.

Delivery of the accommodation

DELIVERY OF ACCOMMODATION

The accommodations are delivered clean inside and outside. During transport (dependent of the weather) the exterior walls can become contaminated. The possible cleaning of the facade is not included. The property will be delivered cleanswept on site.

We assume that the location is easily accessible to our truck (with telescopic crane if required) and service car. We assume a minimum ground clearance of 13 meters. If obstacles are present during execution of work and there are extra hours made you should take into account that these will be recalculated and passed on to you. For the placement, we assume a smooth, even and of course paved area. Should the situation require additional work, we will be happy to make a complementary proposal.

FURTHER CONNECTIONS

The necessary connections of the accommodation to electricity, water and sewage are not included in the proposal. Again, it goes without saying that we can support you in this by making a proposal regarding these works.

FOUNDATION

The accommodation must be posted on a paved surface. Through our unique building concept and application of lightweight materials, mostly a tile base will do. There are various ways of foundation, such as on steel, where you found the accommodation directly on the existing floor (straight on top of it), or by first encave the foundation from the whole at location. Furthermore, it is possible to build a foundaiton with stilts. Obviously, a foundation on steel is less expensive as a foundation on piles.

How to determine if a foundation on steel is possible?

There are several ground pressures in the Netherlands, for example 0.14 Kg/cm² (Municipality of Oostburg, Zeeland), in this case, its capacity would be 1400 Kg/m².

Following an example:

Based on the above mentioned assumption of 0.14 Kg/cm².

With the example of a property in the size 5x2,4m with a weight of about 1200 kg, building the accommodation on 4 tiles of 50x50cm each would be sufficient.

In the inland there are values which can add up to 1 Kg/cm². This results in 10.000 Kg/m².

You can also choose to first dig a small amount, what you get out of the ground can be used again for the realization of a new property.

Example:

Assuming that we dig 60 cm, we will obtain a groundweight per square meter of 0,6 m³ of clay or 0.6 x 2000 kg (specific gravity of clay) in wet weight gives a ground pressure of 1200 kg/m² or 0.12 kg/cm²_.

If you wish to receive further information about the foundation on steel, we refer to the NEN 6744.

Surface workplaces

Employees in the Netherlands are entitled to a safe and healthy workplace. Poorly designed workstations can lead to health problems and accidents. Standards for the establishment of a workplace must ensure that the employer can offer the right workplace.

What are workplace standards?

The key standards for the establishment of a workplace at the office are:

At least four square meters per employee
One square meter for a flat monitor
Two square meters for any other type of monitor
At least one square meter for reading and writing
At least one square meter for the explanation of drawings
One square meter for a detached or mobile drawer unit
For a meeting room applies at least 2 square meters per person.

How are workplace standards determined?

The number of square meters for a department is the sum of the number of employees, the activities and the required equipment for the work. For office work it’s easier to capture than the establishment of work in a factory.

This kind of workplaces may vary considerably due to the nature of various productions, which could affect the application of the standards for the establishment of a workplace. It is, as almost always, a matter of custom-made specific solutions.

Laws and regulations on workplace standards

Article 3.19 of the Working Conditions Decree provides the legal basis for the minimum dimensions of office workstations. Article 3.19 states the following:

The dimensions and the air volume of the workplace should be such that the employee can work without risk to his safety, health or welfare.
The dimensions of the workplace should be such that the employee has sufficient freedom of movement to carry out his work.
If, in connection with the nature of the work, the second paragraph can not be met, near the workplace must be another open or enclosed area available with adequate freedom of movement for workers concerned.

Occupational Health Decisions

The Conditions Decree also provides standards for aspects such as lighting, shading, temperature and the amount of fresh air. The equipment must meet safety standards, but must also be placed such that security is not compromised. There are several articles available in the Working Conditions Decree which make statements on workplace standards:

Article 3.11: Floors, walls and ceilings of workplaces
Article 3.12: Windows and skylights of the premises
Article 3.13: Doors, movable fences and other passages
Article 3.14: Connections
Article 3.19: Dimensions and air volume in rooms: movements at the workplace
Article 3.20: Rest rooms
Article 3.21: Sleeping rooms
Article 3.22: Changing rooms
Article 3.23: Washrooms and shower rooms
Article 3.24: Toilets and washbasins
Article 3.25: First aid posts

Considerations in determining workplace standards

Hygiene is an important part of the standards for the design of the workplace. Floors should be free of blemishes and dangerous slopes. Just like walls and ceilings, they should also be hygienic and easy to clean.
Security is an important issue. Everyone should be able to easily reach his workplace and especially to leave quickly in case of an emergency. There must be adequate fire estinguishers and emergency routes. The emergency exits must be identifiable and free of obstructions.
There must be a well-functioning emergency lighting.
There must be special areas available where employees can take a break from their work. There are special requirements for toilets, washing and changing rooms and shower facilities.
The furniture should be ergonomic. This means: it must we well suited to the job and the people who use it. For example, there must be sufficient space for feet and legs.
Blinding and reflection at the workplace should be avoided.
For a number of industries, there are additional requirements for the standards of the establishment of a workplace (construction, mining and transport industries).

OHD Articles explained:

Article 3.11. Floors, walls and ceilings of workplaces

The floors of workplaces are as free as possible from bumps and dangerous slopes and furthermore as much as possible fixed, stable and stiff.

Tecnical description used materials

Construction

The entire cabin is build out of a galvanised steel frame. Technically, it is possible to stack the cabins up to 3 levels (this on specific request). The galvanized profile of the accommodation can be finished in every desired colour (standard finishing in light gray RAL 7032).

Outer walls

The outer walls are build from separate panels which we unite to one big wall. These panels are, both on the inside and outside, provided with profiled metal plating which protects the core material against external (weather) influences, and ensures the strengt hand rigidity of the panel. Both materials and design are modern and contemporary.

The metal exterior siding is made of Sendzimir (thermal) galvanized steel and finished with a coating, the standard colour we use is gray RAL 7032.

Thanks to the high insulation standard of sandwich panels and the low heat capacity most heat is given out.

The materials and execution are modern, contemporary and provide a comfortable accommodation, whether used as office or living space.

The core is featured with insulation with a unique default value of Rc = 2,77. Optionally, this Rc can be increased to 5,3 or 6,6. Of course, in this case the thickness of the walls becomes 80 or 100 mm.

Roof

The roofs are provided with metal skins, both on the inside and outside, which protect the core material against external (weather) influences, and ensure the strength and rigidity of the panel. The surface is slightly profiled executed, so a high stiffness is obtained. The roof is walkable, and hidden from the view we have installed lifting eyes so the accommodation is also liftable by crane.

The metal diaphragms are made of galvanized steel and are standard coated in gray RAL 7032.

Roof load 220 Kg per m².

Floor

The floor construction consists of a completely galvanized base frame and is provided with so-called tubelars. The insulation pannels are filled with a vapor barrier galvanized sheeting and we have assembled waterproof beams on the floor boards.

Floor load 2,5 kN/m².

Floor covering

All rooms are equipped with a PVC floor covering and plastic skirting.

Windows / Frames / Doors

The frames used for both doors and windows are made of aluminum. We have chosen for aluminium frames because they are very durable. Their lifetime is much higher than that of plastic frames, and especially of wooden frames. Because of the applied coating of the aluminium are also exempt from the painting which is required every three years with wooden frames.

The aluminum frames are 100% recyclable; This fits perfectly with our core environmental theme (CSR and ISO 26000).

If desired, bars can be added to the windows. Optionally, we can also deliver them with double glass, patterned glass, or a shutter.

Inner walls

The inner walls are dotated with a galvanized, smooth and well-detachable steel skin, on both inside and out.

Finished in color RAL 7032. The core is provided with insulation material.

Electric heater

In order to calculate the capacity of the electric heater, we use a rule of thumb. Globally you can assume about 75 watts per m³.

(To get a temperature of 18^oC, you need about 70 watts per cubic meter).

For example, a property with a size of 6x2,2M, an internal height of 2,5M and a total capacity of 33M³. We multiply it by 75 watts, so the required capacity will be: 2.475 watts.
