Cities cover less than 1% of the earth’s surface, but are responsible for 80% of the world’s CO2 output In our cities, only 1% of the building stock is new

We need a solution for the other 99% .....

A responsible, sustainable refurbishment programme is the only solution….

We need a solution for the other 99% .....

So what must we do?

We need a solution for the other 99% .....

Cladding

The cladding design must integrate the building requirements and consider: Insulation and u-values Acoustics Wind loading and structure Glazing specification Weather resistance Maintenance Cost Appearance Natural light

Cladding

The cladding design must integrate the following building requirements: Ventilation Solar heating Photovoltaics Solar shading Security

…..but it starts with simple floor to floor slabs… …which, if exposed, are a major part of the building’s thermal mass and can be used to stabilise the internal environment.

A 1500mm grid is the most flexible for commercial use Insulation panels are introduced to desk height A horizontal glazing zone above desk height maximises daylight Upper areas of glazing are treated to avoid glare…. ….and to project natural light deep into the office

Coatings on the glass filter the sun’s energy allowing maximum transmission of the visible spectrum…but exclude energy that only transmits heat Coatings also keep in heat, improving u-values High performance solar coatings are used on a building’s south side… low-e only on the north

Glass weathers well, lasts and is easy to maintain…self cleaning glass will reduce water use

A typical office ‘manufactures’ cool air in chillers and pumps it around the building….. ….using substantial amounts

  • f fossil fuel.

Cladding

Daniel Morrell Limited The Carbon Advisory Service

slide-33
SLIDE 33

But if we allow the air outside the window into the building…. air need not be pumped far…. fans can be very low power…. …..and the electrical load is greatly reduced. Openings allow the building skin to breathe.

Cladding

slide-34
SLIDE 34

Air enters the floor or ceiling void….. to local fresh air units with variable speed low energy fans …providing local heat recovery, and evaporative cooling…. and allow night-cooling of the building's thermal mass

Cladding

Openable windows allow natural ventilation…. and give occupants additional local control and an increased feeling of comfort.

Cladding

But openings in the cladding raise security issues in commercial properties. Brise-soleil can supplement the performance of glass coatings and counter security issues These security-cum-solar shading features contain photovoltaics, providing energy for the building.

Cladding

Nano-technology will allow energy collection to become cheaper… we now can print photovoltaics onto our cladding components

At lower and upper levels restaurants and cafes, require hot water….. Solar pipes pre-heat water for washing dishes whilst you eat and for showers in the basement gym…..

…. put all together the components of our cladding help us reduce our dependence on fossil fuel… by allowing us a closer connection to the light and air around us.
