Introduction
Location The site is situated in Glasgow, Scotland. It is located towards the Southern perimeter of Glasgow City Centre, at the bottom of Buchanan Street (one of 3 main public & retail axis, the others being Sauchiehall Street and Argyle Street). The site sits within St. Enoch District which comprises of retail spaces and a public square, and creates a path towards the derelict riverside area, known as the fear zone due to the high crime rate within the area.

Introduction Local Climate The site is situated at the coordinates of 55°85’N 4°25’W. Glasgow is typically milder in temperature than most of Scotland, influenced by the Gulf stream. It possesses an Oceanic/Marine climate, typical of West coasts of higher middle latitudes of continents. This results in cool summers and cool (but not too cold) winters, with a narrow annual temperature range, with few extremes of temperature. For the collection of the local climate data, we have used data collected from Glasgow Airport Weather station, situated at the coordinates of 55°87’N 4°43’W. The station is located 11km West of the site. The data has been read using the ASHRAE Standard 55 and Current Handbook of Fundamentals Model. The Clothing Level has been set to a value of 1 and Metabolic Activity, to a value of 1.1. The PMV (Predicted Mean Vote) has been used to measure comfort.
Temperature: Viewing the DBT at 50% humidity, we find that the local temperature falls well below the comfort levels required as calculated by the PMV. Only in the warmest days in the summer months will the temperature be regarded as comfortable. Therefore a mechanical heating system will be required to assist in the heating of the building. A passive design is also paramount to reducing running costs due to the harsh climate.
Sky Cover: The annual sky cover of just under 80% confirms the marine climate of the Glasgow region. Even in the summer months, there is very little variation, resulting in cooler summers. This must be remembered when designing for the use of light. The site will sit under a consistant layer of cloud cover 80% of the year.
Illumination: The direct normal illumination for Glasgow ranges between 8 000 lux - 28 000 lux. An average reading of 15 000 lux. This ranges from overcast daylight to light from blue sky. It will be key to get sufficient light into the building due to the weak overcast daylight, as a result of the excessive cloud cover.
Wind Velocity: The wind velocity averages between 3 - 9m/s. There is no real variation from this apart from the month of January, where the wind is slightly stronger at over 10m/s. Reading the Beaufort scale, this is classed as a light breeze, going up to a fresh breeze. The recorded high of 31m/s in the month of January equates to a Violant storm. Other highs recorded at around 18m/s equate to a gale. When designing for wind, we must design to account for these extremes.
Shading: The chart above illustrates that shading design is not really required due to the extreme cloud cover that exists. There are small periods of the year (72 hours) where shading may heat up the space, however if we look at the low annual temperature range, this sunlight will be welcome into the building. However, calculations will be required for design against glare.
Psychometric Chart: This chart shows that mechanical heating would provide comfort for 66% of the time throughout the year for internal spaces. Internal heat gains: 23%. Solar heat gains account for 10%(25% of daytime). Wind Protection accounts for 6%. The climate is classed as comfortable for only 2% of the time. We must use solar heating where possible to gain heat.

Introduction Wind Analysis The wind rose shows the prevailing wind generally coming from a South Westerly direction, however there is also a secondary wind which arrives from the an Easterly direction. January is the windiest month, with reduced wind velocity during the summer months. There is very little wind from the North. The current site is blocked from the South Westerly prevailing winds by the neighbouring buildings, however the Easterly winds may impact the site, therefore sufficient design will be required to protect the building against possible winds up to a velocity of 17m/s

Introduction
Site & Context The site consists of an area of 2145m2. The site is flat and rectangular in shape, with dimensions of 60m x 35m. It is land locked on two sides by surrounding buildings. The main long elevation is North facing and faces out onto Howard street, predominantly used as a bus route and for vehicles from St Enoch car park. The short elevation is Eastward facing and faces out onto Dixon Street, a local road which continues the axis down from Buchanan street and St Enoch Square. The existing building on site was previously used by Air Lingus and is now derelict, with only the ground floor being used as a local charity shop. There are many derelict buildings around st Enoch square and the riverside, some of these being listed buildings. This area provides oppurtunities for high quality regeneration projects, upgrading the derelict riverside and connecting it to the deprived Southern bank.

1. Building Environment Building Performance There are 2 main types of wall buildup within the design. Wall Type 1 consists of an in-situ concrete buildup whilst Wall Type 2 consists of a timber structure buildup. We will look at data for both wall types in order to determine the performance of these materials.
Wall Type 1: In-Situ Concrete The in-situ concrete external walls are 375mm thick. This is built up from the following materials: - Internal reinforced concrete wall of 200mm which will form the main load bearing structure. - 100mm Phenolic Rigid Insulation - 75mm external reinforced concrete wall of 75mm Based on this material buildup, this wall is calculated to acheive a U-value of 0.20 W/m2K. This is calculated using Passive Design Assistant (PDA). The materials were built using the material builder tool. The graph to the right shows how the material performs within the Glasgow climate. The climate data is taken from an EPW file of Glasgow airport. A condensation assessment has been performed on this material buildup using BuildDesk software. The programme calculates that no condensation is predicted throughout the year in Glasgow. Therefore a condensation membrane is not required within this material buildup.

1. Building Environment
HVAC System - Proposed Layout. tbc by services engineer. (Map not to scale)
Ventilation A hybrid ventilation strategy will be adopted due to the nature of the programme. Spaces such as retail, gym and workshop spaces will require ventilation and thermal comfort to be closely monitored. Therefore natural ventialtion alone is not enough.
PM2.5 is a standard adopted by the European Union, limiting any particulates in air to 25 Âľg/m3. To acheive this in the design of the workshop space, ventilation ducts will be placed at each shipmaking station keeping these spaces well ventilated and free from a buildup of these harmful nanoparticles.
PM2.5: If we view the workshop space, extra care is required to extract the airborne particulate matter and nanoparticles which are produced from the ship making process. 14 | Technical Report

1. Building Environment Heating & Cooling Due to the mild climate of Glasgow, a mechanical means of heating is required to create comfortable internal spaces. A heat recovery ventilation system (HRV) will be used as part of the HVAC system. The diagram to the left illustrates the proposed layout for the HVAC ductwork. The ductwork will run along the ceiling. A services zone has been designed in so that the services do not impede users. The service ducts will run vertically between levels at proposed service riser locations. The heat recovery ventilation system will use the energy from the exhaust warm air of the gym and swimming pool areas. This energy will be collected from the air and used to heat fresh incoming external air. This recycling process will reduce energy on the HVAC system. The input and output systems will be placed within a rooftop services area, free from polluting air at pedestrian levels. Diagram of HRV System, provided by Imperial Group

1. Building Environment Acoustics The design consists of large areas of exposed insitu concrete walls, both on the interior and exterior faces of the building. To counteract this, acoustic insulation will be provided in the form of the formwork cladding system which has been designed. Through acoustics calculations, formwork will be permanently left in place to provide acoustic insulation. These bespoke panels will consist of an extra layer of acoustic boarding which has been specified and installed during the off-site manufacturing process. We will look at the worst case scenario: the gym area, where the walls and ceiling are cast in-situ. The floor is finished in conrete screed. We expect a very poor reverberation time calculation for this space due to the concrete core structure.
Acoustic Insulation - Absorption coefficient of 0.9. Image provided by VINCO Cross Section - Acoustic Insulation of permanent formwork cladding
We will be using Sabine’s equation (above) to determine the Reverberation time for the gym space. The volume of this space is calculated to be 2120m3 Floor Ceiling Wall Glazing Total Absorption

An acceptable reverberation time is around 0.8s. This result informs us that having a bare concrete interior would result in a very poor acoustic space with a reverberation time which is x10 times worst than the accepted parameters.

In order to acheive an acceptable acoustic space, we will recalculate the absorption co-efficient with the addition of acoustic insulation. This insulation comes in the form of wood cladding. The cladding has a co-efficient of 0.9.
The calculation above shows the addition of the acoustic insulation which would cover 1/3 of the floor and ceiling spaces as well as 1/2 of the interior walls. V=2120m3 0.161 x V 0.161 x 2120 = 341.32 T = 341.32/420 T = 0.8s An acceptable acoustic performance level is acheived by the introduction of this cladding. In terms of Architectural design intent, the play on pattern between formwork and exposed concrete can be designed within these acoustic parameters.
Formwork panels specified to act as Acoustic insulation must cover 50% of the wall area in order to acheive an internal reverberation time of 0.8s
Vibration Control: Another issue is the vibration caused by the gym area which is on the first floor. The ground floor level contains retail units, therefore actions must be taken to restrict the acoustic vibration through the concrete floors. We will be adding an extra layer of insulation on top of the structural concrete floor to restrict this vibration. TVS RESi Foam is a low cost, under screed acoustic insulation which is Part E Compliant. The material is a cross-linked, closed cell polyolefin foam which reduces the transmission of impact sound through in-situ concrete floors. The foam is 8mm thick and is a rigid material.

Visual Comfort Having run a daylight autonomy simulation on DIVA, the simulation report confirms to us that only 13% of the floor area would receive 500lux (UK Standard) of light, 50% of the time. However, if we view each square metre of space in the images above, we learn that the lighting is not far off the requirements. The lighting reaches 500 lux around 30%40% of the time. Furthermore, the mean daylight factor of 3.2% is acceptable. To get the daylight autonomy up to the acceptable standard, further skylighting or glazing would be required. | K14ET2 - Environment and Technology 2
However this must be factored in against building performance as well as glare. An updated simulation explores the addition of extra north facing skylighting. With this updated calculation, 78% of the floor area would receive 500lux (UK Standard) of light, 50% of the time.

2. Structure 2.1 Structural Grid
The structural pattern is a result of a form which has been derived out of an Architectural mass modelling excercise. Fig.1 illustrates how the building is split into 3 to allow for a central square, creating a linkage and continuation of the main square. Horizontally the building grid is split at points to allow for access from Howard street
Fig.1. Structural grid derived from mass modelling
Horizontally the grid ranges from GL1 - GL12. The grids are spaced apart 6m c/c, except for the walkways which span 4.25m c/c. Vertically, the grid ranges from GL(A) - GL(G). These are centred at 6m, with the central square being spaced at 5.5m c/c. The grid has been setup to allow for a practical span range of 6m as illustrated in Fig.2. At some locations two-way spanning will be adopted, at some locations only oneway spanning will be possible. The only location with a longer span is the swimming pool area, where a span of 12m is required. This will be possible with one way joists or concrete beams as illustrated in Fig. 2. Fig.2 also confirms that one way and two way concrete slabs are possible with a span range of 6m. It also confirms that timber beams will be more than feasible with a 6m span range.

2. Structure 2.2 Foundation
The subsurface soil on the site consists of Alluvium deposits. These consist of clay, silt, sand and gravel. This type of plain is within a flood zone and is periodically flooded by the River, therefore deep, stable foundations are recommended. The building also consists of 5 storeys, therefore a deep foundation is required to carry the large loading requirements. A bored pile foundation system called the Continuous Flight Auger (CFA) will be used due to the congested Urban location of the site, reducing the amount of noise and vibration. CFA consists of using insitu concrete. Firstly a bored pile machine drills into the ground. . Once the hole is drilled, concrete is poured into the hole. Lastly, reinforcement cages are lowered into the wet concrete. This technique may take longer than using precast piles, however it is very much quieter than drilling in precast piles. Noise reduction will have to take precedence over time due to the central location of the site. The piles are capped with a shallow ground beam which ties the piles together to form a single structural system that can be used as a base to build from.

2. Structure 2.3 Basement Structure
The site is located within a flood plain. For this reason, extra measures are taken to prevent water ingress into the basement area. The detail in fig. 2 shows a 500mm retaining wall sealed in a waterproof membrane. A drainage cavity exists to capture any possible water ingress throughout the building life. An inner lining of blockwork is laid on top of a concrete upstand.

2. Structure 2.4 Concrete Structure
Fig.1. Illustrates sandwich concrete.
In Situ concrete will be used on this project. Due to the Architectural design of producing exposed concrete on both internal and external faces, a sandwich panel will be used, containing a centred 50mm insulation tied in place using a non conductive thermal tie. The walls will provide an overall thickness of 300mm. The floors and ceilings will also be constructed using in situ concrete. Fig.2 determines that a 2 way flat plate of a thickness of 200mm will be sufficient for a 6m span. However, for the swimming pool area which spans 12m, we will require 500mm x 150mm post tensioned beams as determined in fig. 3. Beams are preffered over joists on this occasion due to the preferred Architectural design of the exposed soffit.

2. Structure 2.5 Timber Structure
Model 1 - Exploring the ship making process. Ribs sit on top of the keel to form the structure for the body.
Model 1 - Flipping the model. The keel acting as a central beam with ribs holding it up.
Model 2 - Ribs can be triangulated to create a stronger and more attractive structure.
The concept for the timber structures comes from the ship building process of laying the keel. This is seen as a significant moment in the shipmaking process. The design of the structure intended to celebrate this laying of the keel. The main structure consists of 2 beams which are held up by a series of horizontal ribs. The design of the structure is intended to provide a spaces which reconnect and celebrate the art of shipmaking. Model 3 - Two central keels, set 500mm apart to allow a strip of central light into the building, celebrating the keel. The 2 Keel’s are held up by a series of triangulated timber ribs at a span of every 6m.

Concept inspired partly by Yountville Town Center, California, USA by Siegel + Strain Architects Glasgow Reconnect 27
2. Structure Timber Structure Sizing: Glue-Laminated beams will be used for the main Keel Beams as each of these beams are 35m in length. The beams will be supported by ribs at 6m intervals, therefore, Fig.1 states that the beam requires the minimum dimensions of 310mm x 77mm. However, because of the length of the beams and for the Architectural effect of highlighting the keel, a larger dimension of 500mm x 150mm will be used. Other beams will require a minimum dimension of 300mm x 100mm for a span of 4.25m as illustrated in Fig.2. Beams will require a minimum dimension of 500mm x 150mm for a span of 12m. The ribs which hold up the keel beams are essentially structural arches which connect at the central keel. Therefore, Fig.3. highlights that the required dimensions for these ribs are 350mm x 70mm. However, after deliberating with the structural engineer, a figure of 400mm x 150mm is deemed to provide a much more rigid structure. Lastly, Fig.4 provides dimensions for the timber studwork of 38mm x 89mm.

The design intent for the concrete making process was to provide a formwork system which could be reused as a cladding system. The concrete would provide a timber cut finish, which would relate to the timber cladding. This would provide the building with a tectonic language, providing glimpses of the construction process.

of the bespoke formwork system
We analysed a typical formwork system as shown above and decided on a prefabricated formwork system which would come to site in modular panels. These panels would be connected using tongue and groove joints. The quality of these panels would be high, as the panels would be reused as cladding. The sheating panels would be made from European Larch timber and the stud and wale frames would be from Scottish oak. The outer ties would be coated in Bronze to create a high class finish. The front face of the panels would provide the concrete finish whilst the back of the panels would provide the cladding finish. Some formwork panels would be left in place whilst others would be removed and reused as cladding.
using tongue and grooved joints.
This prefabricated bespoke product would cost higher than typical formwork systems, however because of it’s usage as cladding after casting, additional costs on timber would be greatly reduced, which would go a long way on balancing out the higher costs on this product.

3. Materials & Construction Materials In-Situ Concrete The design intent requires a difference in concrete mix between a harder and stronger front North facade, in contrast to a smoother and lighter rear South facing facade. To acheive this, a fly ash cement will partially replace standard cement. This cement is produced using the ash from the combustion process of coal. It produces a darker looking concrete. This together with a higher conrete mix will provide a darker and rougher concrete finish. The rear facade will have a lower aggregate mix, with cement which is partially replaced with Ground-granulated blast-furnace slag (GGBS). This slag is produced during the production process of Iron. GGBS will provide a paler looking concrete which would appear lighter with the addition of South facing sunlight.

3. Materials & Construction Materials Scottish Oak Timber Scottish oak is a locally produced material which was predominantly used as a traditional ship building material during the industrial revolution.
Left: Use of Scottish hardwood in the design of the structural and internal cladding of the main mixed use space. Below: Example of oak structure texture.
It is a naturally durable material due to its natural production of tannic acids, a powerful chemical which reproduces skin and which provides resistance towards decay. This material is ideal for use outdoors as maintenance on the wood is not required. The material is a hard and decorative wood. it is a darker coloured wood compared to European larch. The material will mainly be used as a structural wood, giving a hierarchy between the oak and European larch, which will be used as a cladding material.
European Larch Timber Larch is a locally produced material which possesses a warm, reddish brown/terracotta colour. This provides a consistent material palette with the colour being similar to the red sandstone which is used elsewhere on the building facade.
Left: European larch is used for the cladding of the rear facade, providing a lighter contrast to the sandstone front facade. Bottom right: Example of European larch cladding.
The 2 materials provide a visual contrast, yet at the same time an association in colour palette. The material will be used as cladding, most significantly being used as the permanent formwork which will double up as the cladding for the ship building workshop. Larch, just like Scottish Oak, is a strong and durable local material which is popular for it’s outdoor usage.

Reflection Environment & Technology has been a very useful and important module for me this year. The simulations which we have been taught have allowed us to apply our theoretical knowledge to analyse and test our designs against environmental factors. Testing especially the acoustics and lighting of my design and learning how they performed allowed me to amend my design and take it to a level where it is integrated. I was surprised to find an extremely high Reverberation time of 8 seconds for my concrete core. This helped me to realise how easy it is to design spaces which do not work. It is important to analyse spaces before they are built as post construction amendments can be very costly. I particularly enjoy using DIVA to mould a lighting design which is diserable both aesthetically and from a visual comfort point of view. As a designer, it is assuring to be able to test designs out using simulation software. It allows the designer to be more confident about their design, knowing that the spaces designed will be both visually pleasing and comfortable to inhabit.

Digital Mockup One uncertain aspect of my design was the amount of lighting the building would get. Especially the workshop space which had an 800mm strip of overhead glazing and a few panels of frosted glass. I was unsure if these openings would provide sufficient light within the overcast climate of Glasgow. The digital mockup of the workshop space allowed me to explore the lighting within the space. The mockups were modelled in 3DS Max and imported into Rhino, where daylight Autonomy calculations were performed using the DIVA plugin. This calculation would inform me whether this space receives sufficient lighting. This calculation would also provide me with a mean daylight factor for the space. UK requirements ask us to provide a minimum of 500 lux for 50% of the time. We learnt that the space provided a figure of just under this requirement at round 30%-40%, however it did provide us with an acceptable mean daylight factor of over 2%. We adjusted the digital mockup to give it extra North facing glazing, This extra glazing provided us with a daylight autonomy result of over 50%. The 2 images below show the 2 design options. This process allowed me to critique my design, analysing the pros and cons of each option, analysing it against how it would affect other building performance criterias such as thermal comfort and ventilation. This digital mockup was very useful as it allowed me to test any unknowns of my design before it is constructed. It is a very useful tool to have at this early design stage.
