1. Getting the Final Layout Right
Above is the first layout I tried which works well, the only reason I have decided to develop this further is the that the showers perhaps aren’t good to be within the main toilets, and I also have a staff room located on the other wing so two of this size seems unnecessary. I have now incorporated a disabled toilet with the shower facilities built in there, this was an issue I had initially as I hadn’t put a disabled toilet in but this idea covers both those problems. I have also designed a ‘rest area’ where staff can go for their morning coffee breaks, or somewhere comfortable for clients to get their refreshments.
Alice Morice
Building Technology CON 286 Building Fabric Assignment Part 1
This is the development of the layout for the male toilets and the staff room, initially the layout was not ideal as the kitchen area needed to be sealed off because of smells etc. Also the male toilets need a second door to create an ‘anti room’ as this is more practical with public toilet entrances for reasons such as privacy and smells. The final layout is pictured below.

2: The Main Office Area
I have chosen a corner desk configuration for the main office area. The reason for this is I feel it is a good use of the space allowing for ideal circulation around the office.
The desks I have chosen are from the Sven Christiansen X-Range they consist of 2 x 1600mm Left hand corner desks, 2 x 1600mm Right hand corner desks, 4 x Desk height 600mm deep pedestals, 2 x 1600mm wide screens and 2 x 1631mm wide screens.

Office and Ergonomics Within an office environment it is important that ergonomics is considered within the design as workers are at high risk of RSS (repetitive strain injury). Office furniture and ergonomics are very closely intertwined. As a matter of fact the word ergonomics comes from two Greek words: ergo, meaning work and nomos, meaning laws. So ergonomic office furniture takes into account how the furniture fits and comfortably supports the people who use it day after day and for long periods of time. Designers and manufacturers take into account how anthropometry, posture, and repetitive motion affect the user to come up with viable solutions for office furniture design and workspace design. Anthropometry Anthropometry is the study of measurements of the proportions, size, and weight of the human body. Since people come in many shapes and sizes, it can help in designing ergonomically suitable products for men, or women, or even school furniture for children. Posture It is essential to maintain good posture throughout the day for the health of the spine. While there is an on-going debate on the correct seated posture everyone agrees that it should not put stress on the user's back, buttocks, arm muscles or feet. The height, depth, width, and angle of the seat all address that along with back and arm supports.
Alice Morice
Building Technology CON 286 Building Fabric Assignment Part 1
In addition to the seated posture, good ergonomic design takes into consideration other workplace postures such as standing, reaching and moving. Repetitive Motion Repetitive tasks can sometimes lead to injury, so minimizing the number of continuous movements can help reduce that risk. This could possibly be one of the most difficult issues to address, as it is
difficult to forecast the number of repetitive movements that a user might have to perform. One factor in reducing the risk of injury and musculoskeletal disorders is decreasing the amount of force required to perform a task. In Conclusion In conclusion, all these factors go into creating an efficiently designed office chair or workstation. Ergonomics has become a very important aspect of office furniture design, and rightly so. Efficient design makes it easy for people to function better and be more productive. Long term damage to the musculoskeletal system and work related injuries can be minimized or avoided.

4. Relevant Regulations How many toilets should a work place have? The relevant legislation is the Workplace (Health, Safety and Welfare) Regulations 1992. Regulation 20, Sanitary conveniences, states: 1. Suitable and sufficient sanitary conveniences shall be provided at readily accessible places. 2. Without prejudice to the generality of paragraph (1), sanitary conveniences shall not be suitable unless a. the rooms containing them are adequately ventilated and lit; b. they and the rooms containing them are kept in a clean and orderly condition; and c. separate rooms containing conveniences are provided for men and women except where and so far as each convenience is in a separate room the door of which is capable of being secured from inside.

Provision of sufficient workspace & welfare facilities Regulation 10 of the Workplace, (Health Safety and Welfare) Regulations 1992 states the following with regards to room dimensions and space requirements: Every room where persons work shall have sufficient floor area, height and unoccupied space for purposes of health, safety and welfare. The associated Approved Code of Practice and Guidance goes on to state: Workrooms should have enough free space to allow people to get to and from workstations and to move within the room, with ease. The number of people who may work in any particular room at any one time will depend not only on the size of the room, but on the space taken up by furniture, fittings, equipment, and on the layout of the room. Workrooms, except those where people only work for short periods, should be of sufficient height (from floor to ceiling) over most of the room to enable safe access to workstations. In older buildings with obstructions such as low beams the obstruction should be clearly marked. The total volume of the room, when empty, divided by the number of people normally working in it should be at least 11 cubic metres. In making this calculation a room or part of a room which is more than 3.0m high should be counted as 3.0m high. The figure of 11 cubic metres per person is a minimum and may be insufficient if, for example, much of the room is taken up by furniture etc.
Alice Morice
Building Technology CON 286 Building Fabric Assignment Part 1
The figure of 11 cubic metres does not apply to: a .retail sales kiosks, attendants' shelters, machine control cabs or similar small structures, where space is necessarily limited; or b. rooms being used for lectures, meetings and similar purposes. In a typical room, where the ceiling is 2.4m high, a floor area of 4.6m2 (for example 2.0 x 2.3m) will be needed to provide a space of 11 cubic metres. Where the ceiling is 3.0m high or higher the minimum floor area will be 3.7m2 (for example 2.0 x 1.85m). (These floor areas are only for illustrative purposes and are approximate). The floor space per person indicated above will not always give sufficient unoccupied space, as required by the Regulation. Rooms may need to be larger, or to have fewer people working in them, than indicated in those paragraphs, depending on such factors as the contents and layout of the room and the nature of the work. Where space is limited careful planning of the workplace is particularly important.

Fire Exits & Signage In the UK there is a lot of legislation in place with regards to health and safety in the workplace or where large amounts of people will congregate. Just as all businesses should ensure that they have first aid kits and fire extinguishers in their premises they must also make sure that they have the relevant fire exit signs installed. In a building each door that is used as the final exit point for the evacuation of people from it when a fire occurs should have a fire exit sign above them. Plus there must also be one situated at the main entrance along with the fire exit doors from the relevant areas in the building. Plus other fire exit signs should be situated above the doors that lead into and out of every room in the building. The signs that are used in the UK today are ones that must bear either a picture or symbol which clearly defines what the sign is. In many cases along with the sign saying fire exit or a picture of a person walking through the door other signs may be displayed as well. One of these may well be a floor plan that clearly defines the routes to be taken when a fire occurs. In most cases on these types of signs used for denoting fire exits the route will be marked in red whilst all other routes around the building will be marked in black. It is important that all fire exit signs are not placed too high and should be clearly seen from all areas of a room. In many cases today companies are now investing money in purchasing photo luminescent signs as these glow in the dark, especially if they cannot afford to install emergency lighting. As is mandatory by law today in the UK all routes that will be used to exit a building in the event of a fire must be clearly marked with signs. It is important that the signs being used are ones that comply with the current fire regulations, which if you are unsure about your local Fire Office or a professional fire risk assessor should be able to confirm what these are.
Alice Morice
Building Technology CON 286 Building Fabric Assignment Part 1
All the fire exit signs can have wording on them they must also include a symbol as we mentioned above. If you have signs in your building which merely say “fire exit� these are in fact no longer legal and so will have to be replaced with those that are. The one sign that is the one you are most likely to see within public buildings, offices and factories today is the one that shows a person going through an open doorway. However, there are other fire exit signs that are used and these can be seen around Europe and show a person moving towards a door. It is important to recognize both of these symbols so you know exactly what they are and why they are there.
Fire Doors: FD30 FD30 Fire doors stops fire from spreading for a guaranteed 30 minutes. The should be installed in all workplaces.

Recommended System Simultaneous VRF Systems – Practical & Economical The simultaneous system that can provide heating and cooling at the same time. This can also incorporate a VRF boiler, which can provide hot water from the same system. On most commercial and industrial applications this would be a great way to reduce energy costs, as heat removed from the building could be directed into your hot water systems. The stand alone boilers are available as air to water systems or ground to air systems and can be used to provide hot water to either existing radiators or to under floor heating systems.

The traditional 'vented' hot water cylinder operates with a header tank and generates lower water pressure than an unvented cylinder. In 'direct' units the water is heated by one or more electric immersion heaters. In 'indirect' units the heat source is an external boiler that circulates hot water through a coil heat exchanger within the cylinder. In practice indirect units also have an electric immersion heater as a back-up in case of boiler failure. Indirect cylinders are generally more expensive to purchase and install but usually result in faster reheat times as much more heating power is normally available from a boiler than from electric immersion heaters. Direct (all-electric) units come into their own when a gas/oil boiler is either not available or too expensive to install, or in situations where the requirement for annual gas safety checks of appliances, flues and pipework is considered onerous, for example at rental properties.

3. Heat Loss Calculations How to calculate the heat loss of a room… Temperature lift = Internal temp. - ambient temp. The heat loss for a structure is calculated by taking each surface in turn, calculating its overall area and multiplying by its thermal transmittance co-efficient or ‘U - value’ (see table) Heat loss through surface = width(m) x length(m) x U value Note the area of windows and doors should be calculated and deducted from the area of the surface they are in, and their heat loss should be calculated separately. The total surface heat loss for the structure is the sum of all surface heat losses. Total surface heat loss = loss for walls + loss for roof + loss for floor + loss for windows + loss for doors An allowance should be made for heat loss through ventilation, which also includes leaks of air through badly fitting doors, windows, damage to the structures surface etc. Putting a value on this can be very difficult, figures range from 20% to 66% depending on the type and condition of the structure. Total heat loss = total surface heat loss x allowance for heat loss through ventilation Finally to calculate the heater size needed, the total heat loss is multiplied by the temperature lift. Heater size required = total heat loss x temperature lift.
Alice Morice
Building Technology CON 286 Building Fabric Assignment Part 1
The room I have calculated the heat loss for is the disabled WC…
Temperature lift = 20 - (-5) = 25 deg. C
Area of roof = 2675 x 3021 = 12.9m² Area of walls = (2x3x2675) + (2x3x3021) = 34.2m² Area of floor = 2675 x 3021 = 12.9m²
Heat loss through roof = 12.9 x 2.85 = 36.8 W Heat loss through walls = 34.2 x 1.6 = 54.7 W Heat loss through floor = 12.9 x 0.7 = 9.03 W
Total surface heat loss = 100.53 W
Assuming 20% for heat loss through ventilation Total heat loss = 1.2 x 100.53 = 120.6 W
Heater size required = total heat loss x temperature lift = 120.6 x 25 = 3,015 W
