This drawing shows the wider scoop of the building the horizontal area that I have chosen to detail highlighted, whilst the levels of the rest of the building are highlighted to show this part of the building in it’s surrounding context and overall strategy

Within this study and the wider aspect of my Thesis Project the Memory Museum within my scheme acts a building typology which makes reference to building details, characteristics and rules within it’s development. The Museum Exhibit is developed to catalogue the community conditions of the neighbourhood whilst they still exist and integrate them in to an exhibition and conversation space to encourage conversation, recording or memory within the local community as means of cataloguing community relationships in details before they disapear.

The following report looks at ‘Museum’ Space within the larger master plan of workshops and paper production. The Memory Museum acts as a way of housing exhibits through an experiential exadurated environment. The development of this detail study is integrated with strategies I investigation in the DSIT B report and have applied within this study. The building incorporates material proporties and application previously researched in terms of foundations, material and structural properties.

Within the basement space of the building the construction and application of weather proofing techniques is applied in two different ways.

The main structure of the Memory Museum Building is a Glulam Timber Frame which supports the structure above the Basement level. Above the basement level lthe structure intergrates a timber framed paper screen envelope and atrium along with treated timber and glass facades to create a transparent and adapatable facade which seals the building, but is adaptable. The buidling makes use of a layering of envelope integration to protect the building from external condition. The Basement area of the Museum is excavated in part with the open excavation area supported through the use of retaining walls, whilst the sealed basement area of the archive makes use of reinforced concrete retaining wall construction and the adding of an ‘internal’ layer of Rammed Earth in sections for thermal quality. External rammed earth walls above ground level are constructed off a concrete podium deck at ground floor level. This will be make the basement service block of concrete construction and allow for a rammed earth structure to be transferred through the concrete deck to the pile.

The building utilises retaining wall properties as well as Rammed earth sections wall within parts of the basement. Concrete and rammed earth within the basement allows the building to retain the thermal properties of the surrounding earth and rammed earth walls will be utilised within the service block of the building above ground level. Alongside this the building will integrate a thermal labrinth system to store the high thermal properties of the building which can be utilised during warmer periods, and to conditon the archiving and research spaces of the building.

Legislative Framework

Part A Structural Safety

Park K Protection from falling

Part M Access and Use

Part N Glazing

In the development of my building, adherance to Legislative Framework is essential to the structural integrity of the building.As the development of my building in being developed in accordance with Building Regulation guidelines I will outline when and where regulations have been appleid and considered within the framework of my building’s development.

Within Part A Regulations Structural Safey is considered and outline covering the buildings structure and it’s application to conditions within the environment it is placed. Through my application of building tactics they structural safety is considered.

Within the designs development appliation of Part K Building regulations will be adhered to in the protection of users against falling, collision and impact. Within the building due to the buildings nature and design there are areas of stepped access, but lifts are incorporated at all floors to allow for access to floors. Ballustrades are incorporate at a height of 900mm internally with 1200mm balustrades incorporated in external areas.

Part M outlines regulations to the accessibility and use of the proposition. The building will incorporate these regulations when neccesary and highlight when they have be noted

Glazing incorporated on the facade and internal areas of the building will structural strengthed and braced at points.

Within Tokyo the building building must be considered to withstand soil movement and particularly strength against earthquakes. As highlighted and discussed in DSIT B the building utilises a the key Glulam frame as the transferance of load throughout the building and applied to Pile foundations

The Foundations’s of the building have been carefully considered given the buildings location in Tokyo and additional load transferrance for the building in support of the Glulam Timber Frame is supported through the use of Piles

The building is accesible to both able bodied and non able bodied users. There are spaces where details of the building have been exadurated in to the narrowing my corridors to emulate Japanese details and charactertics of stepped areas on entry. In these areas disabled users will not be able to travel due to the nature of the space. Access can be granted in to the the open public spaces thorugh external exits. Application for handrails and tread and rise angles on stair cases are adhered to..

In the excavation area as highlightied in the section and detail, this side of the building will remain essentially open so users can access earth below for ‘excavation’. Due o the nature of the space and the stairs open from the outside a drainage system has been intergrated to capture downfall from the external part of the building. Alongside this within the excavation area I will integrate a subpump where the earth gradient is use to remove excess moisture to the lowest point from the excavation area. The Excavation is seperated in the ‘interior’ basement area which will be fully tanked and sealed from external ground condition. The internal interior space will adhere to the BS 8102 :2009 Code of practice for the protection of structures against waterproofing from ground condition. Within the ‘internal’ archive basement area, this will be tanked up to Class 4 according to the British standard. This will include a cavity tanked with internal drainage along with peremeter land drain.

Durability As highlighted within the DSIT B report the building integrates the use of 4 key building materials within the building in the form of Concrete rammed earth, glulam frame and paper external envelope. Each of these key materials was selected due to their properties in durability. In the case of the rammed earth walls the mixture with add a concrete addive in order to increase their their stability and endurance, as well as durability.

To improve durability of washi paper integration of screens a wax additive could be lined on the paper shoji screens Sustainability In the development of my proposition the intergration of traditional building practices was integral to the overall project proposal and have been applied in the planning of space etc. Through development the washi paper resource and integrating this as part of the building envelope the continued development of this resource will be utilised. The integration of the Glulam structure within the the basement and external conditions is utilised due to it’s durability performance. Integration of rammed earth walls within the basement from thermal properties and built up from ground floor level integrate the use of excess building materials.

Communication & Safety The Area of Yanesen within Tokyo is a quaint tourist area that can often be described as indicative of a the slower more peaceful way of life that Japan represent 50 years ago. As a result the Memory Museum has been developed as a community resource so crime prevention is not considered in the overall building strategy as I intended it to become a community resource and I don’t see it as threatened. During construction heres fencing will surround the peremeter. The project is located in a picturesque part of tokyo and centrally located so information of the project will be spread through word of mouth, and as my ‘Client’s’ are the Yanesen Magazine and ‘Municipal’ heads of the area, word will be spread through them.

The Glulam Structural frame is used to to it’s high performance properties and durability of environmental conditions.

Environment and Energy Consideration Overview

Ventiliation

Heating & Cooling

Solar

The hierachy of space within the ‘Memory Museum’ has been designed to allow for the overall design of the spaces to be complimented by external environmental conditions which are utilised and designed in the development of overall heating, ventiliation and solar shading strategies considered in DSIT B

Through the integration of the main atrium space within the building the project will be complimented through natural ventilation to the key internal communal spaces. At varying points around the key conversation space of the building, the integration of shoji screens as part of the buildings envelope allows for the opening and closing at varying times to the outside elements, encouraging cross ventilation and sucking air through the lower areas of the space.

The main source of heating and cooling will be utilised through the integration of a thermal labrinth within the controlled archiving and research areas in the Memory Museum. By integrating the labrinth in to the design of the lower controlled spaces of the building, it allows for the thermal mass of the reinforced concrete retainin walls, along with the rammed earth structure above ground floor to retain it’s thermal properties and be used to cool and heat the building at varying times..

Due to the building’s orientation it will make use of solar gains through out the course of the morning and mid afternoon. When the faciility is used in the winter months or on evenings, and the integration of artificial lighting will be utilised within the central void space in order to lighting the changeable lecture space. The highest point of the building has been designed as the atrium space to utilised solar gains and avoid shadows from surrounding buildings as investigated in DSIT B

The Key highlighted offers a reference point to the investigation undetaken in DSIT B as the exteral environmental conditions of the site in regards to the sunpath and predominant NE & NW winds to the site.

Legislative Framework

Part E Acoustics

Part F

Within Part E regulations outlines, the building should follow in relation to sound and proofing against it’s transmission in particular areas. The Main service block of the building is insulated through the application of insulating internal walls alongside rammed earth external walls above ground level which have high sound absorbing characteristics which make it a great acoustic insulator of service noises in the the open public spaces.

Within Part F Regulations oulines for the correct ventilation of building and spaces in defined. Within my building my strategy looked towards creating a space which utlised external environmental conditions whether possible in order to minimise mechanical systems throughout the building. The integration of the atrium space allows for cross ventilation techniques to be utilised and drawing air through the space. Alongside this the intergration of shoji screens as part of the building envelope allow these to be opened at varying times to suit the users needs

Part l2B - Conservation of Fuel and Power Mechanical Application When considering ventiliation regulations the building will be fitted with extractors to the outside as required of all sanitary, washrooms and food prepartion areas within the service block Mechnical extract ventilation to be applied with the rooms at a rate of : Kitchen 60 L/sec rate Toilets 6 L /sec rate

N

Within Part L2B regulations are set out in relation to power and fuel conservation within new buildings. On selection of material choices I considered the environmental application and thermal benefit of the use of rammed earth and it’s thermal properties within controlled and service areas. Alongside this the integration of the thermal labrinth to store energy to be used for cooling at heating at varying times. Alongside this the planning of the building ensured the integration of a central ventilation space to improve ventilation and cooling tactics in order to reduce the application of mechanical systems.

Material Considerations Rammed Earth

Shoji Screens

Through the intergration of excavation material within the rammed earth rammed service core, the building sustainably re-uses a ground condition resource. Additional Benefits are provided through the thermal properties of rammed earth material. Intergration of the key service core within the retaining wall basement further taken advantage of in the basement lining application and then service core.

Integration of Shoji Screens in building aesthetic and ventilation applications towards the buildings developmen became an integral part of the building envelope. Above the basement area the screens act as the main ventilation building envelope which can be opened and close at varying times. They also incorporate layering elements to the space and

Natural Lighting

Artifical Lighting

Acoustics

Public Spaces within the building make full use of the natural lighting throughout the early morning, through till the afternoon. These spaces have been positioned to gain full advantage of the sunpath during daylight hours.

Artificial Lighting is utilised throughout the rammed earth service core above ground level The area of this building is where the service activities such as the archive, kitchen , private meeting and storage areas will be placed. Within these spaces due to their nature controlled lighting will be integrated and serviced through the service core for service requirement spaces and private meeting rooms.

The Nature of the building lends itself to being open in terms of within the main atrium space, I want the conversations of the people within to move through the space. On the other hand the the basement area and service core make use of acoustic insulated plaster board to dampen the sound in the more private areas. Isocrete acoustic screed is used as a layer within the floors to dampen sound throughout the spaces.

Natural Lighting

Ventilation

Cooling

Through the integration of the atrium space and the application of the shoji screens as a part of the building envelope, the building is able to utilise air flow through the building as a key means of ventilation of the public spaces. Movement of air through the space will be wind induced depending on positions and openings in the atrium and shoji screens through different periods.

Heating

Through the integration of the atrium space the building is able to utilise a cross ventilation cooling system throughout the larger part o the building. Through the intergration of the atrium syste, which will incorporate openings in the side panels, and through the opening of shoji screams at varying levels or times of the time the building will be cooled through air flow. Also the thermal mass properties and the thermal labrinth allow for the slow releasing of cooling to the building at warmer periods

During the Summer the building will utilised solar gains during the day and and retain the heat with the rammed earth structure of the service core and through to retaining these properties within the thermal labrinth. The energy source will then provide the main source of heating within the night and winter months.

Within the basement artificial lighting will be integrated in the lighting strategy of the space. Due to the nature of the space being both an archive and research area, lighting will need to be controlled both for study and for preservation. The space is improved asthetically by the integrationg of a glass void in to the research space but light will only reach the space during the day and will not be enough for the area’s activities.

During the Summer months a mechanical ventilation system will have to utilised to move air through the space. Due to the controlled nature of the archive space the air can remain stagnant. Within the research area though mechanical ventilation will be utilised.

During the Summer within the archiving space the area is controlled from over-heating through the slow release and cooling properties of the integration thermal labrinth. Retainig walls will provide heating properties from the surround earth

Services and Integration

Catherine Wheater c3242669 DSIT C Ground Floor Plan Existing Main sSewage

Services Intergration Within the Memory Museum the building has been positioned to allow for a key service core to the back of the buiding, utilising the thermal properties of rammed earth in it’s incasement above ground level and supported through the integration of a concrete podium and retaining wall at basement level as support and thermal properties. Through this planning it allows for power sources, water supply and pipework to run through the building vertically. Through the integration of the service core it has allowed for a freeing of public and open spaces to the front of the building and remove disruption from the planned ‘exhibit space’s’

Within the sealed area of the basement, the wall is lined and built upwards as a concrete podium from which the rammed earth service earth service core is built and positioned at the back of the building. positioning of the service core allows for access of pipework and waste management systems to be integrated in the private service areas and to be hidden at the back of the building, alongside this space can be used for varying functions such as staff access, disabled access, material drop-off and fire assembly and access points

Material Store

The site is situated within a residential neighbourhood, though the plot of the land that is being used for my proposition is a disused carpark previously. Due to this the area has allowances for vehicle access and material storage and transferrance on site. Parralel to the site as highlighted in my DSIT B report the site runs parralel to a main public highway called Shinobazu Street and can access the site which is unofficially a pedestrian street though, cars can access for deliveries and material maneuvering.

Given the nature of the project and the Memory Museum acting as a catalogue to reference details in my ‘workshop’ and paper production areas in the larger master plan, the storage of materials on site will be transported to and from these workshops and built utilising a ‘just in time’ approach to the buildings development. The glulam frame acts as the primary and permant structure of the building wheres parts of the screens and paper used within the space can be removed and changed when written on or more workshop details are provided.

Given the nature of the my thesis project as a whole the application of insitu construction techniques support the ethos of the Memory Museum’s development. Integrating typical building techniques in the shoji screens and paper screening in a secondary structure basis will be supported by ‘insitu’ detailing workshops highlighted in the DSIT B Masterplan. The use of excavated earth will be utilised in the rammed earth service core. The structural glu-lam frame of the building will be pre-fabricated and transported to the site with othet techniques taking place around this structure.

The Project aim is to use this site as a changing environment as the neighbourhood evolves. Initially though it is acting as a catalogue to reference details from the surrounding neighbourhood to exadurate the neighbourhood conversation spaces that traditional Japanese architecture has encourage. Alongside this the space acts a space to re-tell stories, or record memory through writting on paper screens that will be hung intermittedly throughout the building.

In developing an environmental stategy my project looked at using the existing environment of the neighbourhood as inspiration both technically in applied techniques in the building, spatial layout, sizing etc, but also physically in materiality in the unearthing and use of rammed earth; using waste materials in the buildings basement excavation. The excavation undertaken to create the basement and movement of soil at the front part of the building is used as a construction tool and repurposed for it’s thermal retention qualities in the vertical service circulation supported and transferred upon a concrete podium, alongside lined the walls on the interior archive space in sections

In keeping with the applied lessons highlighted in DSIT B that I’ve studied within Japanese architecture the building utilises layers in the fabric and arrangement of the building footprint. The Basement area acts as a seperate part of the building with the retaining wall lined around the building footprints peremeter to create the ‘excavation’ space and then lined and sealed within the internal archiving and research areas. The retaining wall and added 500mm layer of rammed earth in sections provide thermal properties which create a controlled environment for the archiving of artefacts, old interview notes etc. The Service core of the building creates a concrete podium from which the rammed earth structure can develope in the a service core

Legislative Framework Loads

Part A Structural Safety Part A Structure Building Regulations outline regulations that cover building structure movement and applied loads. The intiail use of a Glulam Timber Frame was considered in application of the project due that the fact Tokyo suffers from earthquake and movements. The application of Pile foundations to support the main glulam frame of the building ensures it’s structural stabilty is not comprimised during periods of earthquake. The application of a cantilevered retaining wall in the support of the rammed earth structure ensures that wall is sufficiently supported during periods of ground movement.

Bracing tensions roads

As outlined in DSIT B The Main Glulam Structure transfers acts as a strengthened support above the typical wooden structures of Japanese housing. The Glulam Frame offers a superior means of supporting and transferring loads throughout the building. Additional bracing is added through tensions rods through the frame of the building to ensure increased stability.

As highlighted on the exploded diagram, Deads Loads are transmitted throughout the building through the integration of the Primary structure of the Glulam Frame. The integration of the glulam frame in connection to the Pile Foundations ensure that loads are transferred throughout the building. In areas where void spaces are created, addition beams and rings beams are added and supported on steel plates Within the rammed earth service core the concrete podium provides the structural transferrance of the load bearing rammed earth structure built above ground level

Intermitedly Timber Joists are used to transfer the live loads of users within the space throughout to the Glulam structure. In areas where void spaces are integrated in the floor structure the use of timber ring beam allows for the integration of structural glass voids. Tension Rods are intergrated in glazing areas, and timber bracing is integrated in to internal and timber framed pannelings walls to support the lateral and horizontal movements applied by live and dynamic loads

Giving the stability of the structural frame and integration bracing in the internal and external envelope the building will withstand live wind loads from the NW and NE.

The Architecture of my building will make use of a number of structural systems layered upon the building but these can be defined within the three categories outlined as Primary, Second and Tertiary Strucures. Through utilising these systems the building will ensure that is it sealed at key points to support the overall building strategy alongside support environmental conditions and tactics applied to the building. Through the application of these systems the building will withinstand the addition strain of loads through the movement of people, objects and it’s environment.
