Sanitation.

Recently the bathrooms have become sanctuaries of expression.

Toilet types.

In wall cysterns are placed between the studwork (89MM) of the wall.

Back to wall- see above

Toilet sweet- Generic toilet

Wall mounted- canter levered over the floor with steel frame built into wall.

Mains flush- no cistern, the flush comes from a holding tank and is pumped round when needed. Only cost effective once there are 5 toilets in the building.

 

Showers

Always think ahead so you don’t have to get in the shower and turn it on, hence standing in the cold steam of water, position further back

Sinks.

Taps flush mounted into counter top. Lots of for thought for this!

 

Tiles

Can be left until last minute.

Considering the grout lines.

Coloured Grout (White tile, black grouting)

English bond pattern for grouting.

Stone

Slip matching and book matching marble sheets, way they line up.

1200X2400mm sheets

Composite stones are made of ground up natural stone that’s formed into a slab.

Caesar stone is a brand of composite stone.

Pink marble is grey.

Huf Haus

Huf Haus is a German company based in Hamburg.

In 1912, Johann Huf founded a carpentry workshop in the small village of Krümmel in the Westerwald. A year later, the enterprise moved to Hartenfels. In 1948 his son Franz Huf took over management of the enterprise, and enlarged it to a supra-regional provider of carpenter’s works, e. g. churches in the Rhineland, the large post administration office in Bonn (1950) as well as the German and Arabic pavilions at Expo 58. The so-called “Huf Fachwerkhaus 2000” was designed in 1972 together with the architect Manfred Adams.^[The principles of this construction are still the standard in all Huf houses. Since 1996, grandsons Georg and Thomas Huf have led the company and brought the products to the world market. They also established “The Huf Haus Village”, a collection of Huf family houses, which represent the possibilities of building Huf houses.

On 20 September 2011, Thomas Huf died aged 51.

New design

Near the end of 2009, Huf Haus started new designed houses which the company calls “evolutionary” in its post-and-beam architecture but “revolutionary” in energy efficiency.

Because the expressive symbiosis of wood and glass finds recognition at major international architecture and design competitions, and among Huf Haus clients, who also acknowledge that it can be individually designed, the main stylistic elements have not changed.

Despite the generous use of glass the Huf Haus houses require only a heating rate of 34 W/m² (at Hartenfels, Germany). The main reasons are:

• All constructional wood elements are fitted with a heat-insulation layer put together at the factory – this reduces thermal bridges.
• The already well-insulated walls have been redesigned. The walls are thicker now and their depth can be varied depending on the climatic region. The material used is tailored to the location, so that an adequate heat insulation is achieved.
• The glass walls have 51 mm triple glazing with a heat transfer coefficient (U-value) of 0.6 W/m²K.
• Home technology is based on a heat pump, electronically regulated heating systems, under floor heating pipes laid very closely together, a highly efficient ventilation system and independent domestic hot water pumps, so that the independent heating system can be switched off during the summer months.
• A large photovoltaic system across nearly the whole roof.

Sustainability.

What is sustainability?!

The quality of not being harmful to the environment or depleting natural resources.

The sustainable design approach.

Environmental.

If using timber, is it being re-planted to counter its use?

Buildings use at least half of the energy consumed in the UK, and consequently, produced half of our man made carbon monoxide ( the major greenhouse gas.)

Social

The gap between Rich and poor:

The rich: 20% of the world’s population- receive 80% of the worlds income

The poor: 20% of the world’s population, receive 1.5% of the worlds income.

In the UK our use for energy has increased by more than 70% in the last 39 years. The questions is have we become 70% happier or healthier in this period.

The process of industrialisation in the western world has been based on an economic various.

Economic

Sustainable design sits between environmental, social and economic boundaries.

History

Vernacular

Vernacular architecture is a category of architecture based on local needs and construction materials, and reflecting local traditions.

Japanese sustainable architecture, very first time it has ever been concidered.

Tatami matt—set dimensions—build the rooms around a set size mat.

Looking at using local materials and skills

Responding to the climate

Creating a link to nature

Exploiting new technology

Avoiding excess and waste.

Building to last.

Architecture and the city.

Dongtan will be a zero pollution largely car free, renewable-energy powered, sewage recycling, green fringed utopia.

Commercial interiors

Living sustainability.

Sustainable commercial interiors.

Materials

Hardwood VS softwood.

Café bar interiors

Reclaimed timber.

Reclaimed aluminium

Timber

Natural composites and recycled acrylics.

Student examples.

The issue of sustainable development is the single most important challenge facing the design industry today.

Selecting materials- Appropriate!

Substitution: Choosing flooring made of bamboo, over one made of endangered hardwood.

Sustainability of natural resources.

Energy consumed during purchasing process, transport etc.

Durability

Impact on human health.

Embodied energy

The sum of energy required at all stages of precaution

Extraction of raw materials

Transport

Energy used in processing

Energy used during construction/application.

Highly process materials such as metal and plastic have high embodied energy.

Locally sourced materials that do not tend to travel between origin and have a lower embodied energy.

Questions to ask myself.

How is the material going to be used?

Improves durability

Improves structural performance

High thermal mass?!

Recycle and reuse

Direct recycling- using materials salvaged from other buildings/interior. REUSE.

Recycling consumer industrial waste.

Recycling process consumes energy; the material product can be lower grade.

Where did it come from?

What went into it?

Can it be used safely to make something else?

Does it nurture the health and well-being of its occupants?

Will it be comfortable without requiring a lot of energy for heating?

What chemicals might this product emit during its lifetime.

What is the future of sustainability?

One accident every 3 minutes.

95% are broken bones

90% are on a smooth surface.

Altro has Sustained slip resistance because silicon carbide and aluminium oxide inside. Does not wear down.

NO such thing as a ‘NON-SLIP’

Only ‘slip-resistance”

Slip resistance for 16 years has been proven..

Specifying what and why?!

 

Hygiene

PVC hygienic wall sheet.

Most slips happen because they’re not maintained correctly.

Has to be rinsed with water after been cleaned with detergent.

Sustainability

Altro claim they wouldn’t fill up a domestic skip in a year with all their waste.

Altro created a scheme called recofloor.

Ethical thing to do re

Gave away products used at London 2012 Olympics to be used in schools.

Lamps and Luminaires ( a lamp is the technical term for a “bulb”)

Bulbs/lamps

Lamps are what the public call light bulbs.

Categories of lamp

Incandescent (halogen)

Electricity heats the tungsten filament in the bulb until it glows

Very inefficient

90% lost as heat.

Filament within a vacuum (argon/nitrogen)

Fluorescent

Lamps work by passing a current through a tube filled with argon gas and mercury.

This produces ultraviolet radiation that bombards the fluorescent coating on the inside of the glass tube causing it to emit light.

Efficient, producing very little heat.

Traditionally poor cri rating, but can now get daylighting Lamps.

T12, T8, T5 ( T refers to tube, number diameter)

Compact florescent

Work in the same way as a florescent tube.

Plumen company.

High intensity discharge (HID)

Metal halide

Mercury discharge

High pressure sodium

An electrical arc is crated across tungsten electrodes; The tube is filled with gas and metals.

Metal halide lamps crate a whiter light than other HIDs and are the most common for large interior spaces.

Also known as High Bay Lighting

“Romsey reflector” is the most common

Low pressure sodium

Street lighting

Rare

LED (light emitting diode)

Colour changing potential

Low power consumption and have long life span (11 years)

Lampshades and Luminaires

Free standing, table floor

Surface mounted, ceiling, pendant.

Recessed –ceiling/wall

Light and energy.

Colour temperature measured in degrees’ kelvin.

3000k-very warm-sunlight-high pressure sodium-candle-incandescent lamp-florescent triphosphorous coating.

4500K- metal halide

6000k-very cool-summer light-mercury-sunlight at noon-overcast sky-

10000k-extremely cool-north light-blue-sky.

Colour rendering index

Natural light shows flowers in their most colourful beuty

fluorescent with a high colour rendering shows all colours with a bluish appearance

Metal halide loses some appearance in red but still gives good colour

Fluorescent with a low cri rating has a poor colour rendering.

Concepts and definitions.

Lumens = the total light output.

The luminous flux from a typical 100W incandescent light bulb is 1740 lumens, a 58W florescent delivers around 5,300

Illuminance

This is the luminous flux or light energy emitted by an object that arrives at or strikes a surface and is defined as lumens per metre square or LUX

Examples of LUX levels

A full moon has an illuminance of 1LUX

Street lighting is 10LUX

Operating theatre is 10,000 LUX

Sunshine is 100,000 LUX

Walkways-50LUX

Loading bays-150 LUX

Classrooms 300 LUX

General offices 500LUX

Drawing offices 750LUX

Precision assembly 1500 LUX

Minute assembly 2000 LUX

Where illuminance expresses the luminous power on a surface, the luminance describes the light given off by this surface itself.

Glare

Glare is the discomfort of impairment of vision caused by and excessive range of brightness in the visual field.

Disability glare is where the glare lessens the ability of the eye to see detail, but does not necessarily cause visual discomfort
