Domestic hot water

Traditionally, domestic hot water has simply been a choice between a combi boiler or a vented system (with the odd Point of Use water heater thrown in).

With water saving design, and zero carbonbit of a slippery fish. It tends to mean that a building uses no carbon (oil, coal, etc) to heat it (meaning […]

Emitters (radiators etc.)

Central heating

Emitters tend to be of two types – traditional radiators and underfloor heating. It’s a bit of a toss-up as to which is better. They have their respective advantages and drawbacks.

Underfloor

a pleasanter heat because it is better distributed no wall space taken up by radiators possibly more efficient because of lower […]

Flues

Flues are pipes or ducts which carry waste gasses away from a building to the air outside. This can work in two different ways:

the exhaust gasses are hot and rise naturally up the fluepipe to conduct gas, typically ventilation air or boiler exhaust. see Flue by convection (as with a wood burning stove or […]

Service Ducts

June ’12

The close grouping of services and the placing of them in a fairly centrally situated service duct, usually a duct which extends vertically through the house, has a great deal to recommend it but is seldom executed well.

The schematic above shows a simplified services layout with a service duct which houses […]

Alterations & Fashion

‘Energy use’ is usually associated with how much energy is used to construct a new building. However, this is only part of the story. Most buildings get altered and repaired and redecorated a considerable number of times during their lifetime and taken to an extreme, some houses are constantly having ‘makeovers’. This can vastly increase […]

Telecoms/Home Automation

There are many possible uses of home automation which can enhance the green rating of a house but probably the most obvious and least used is the ability to turn off heating for periods when the house is not occupied and then turn it on remotely before returning.

See technical blogs such as the Wiring […]

Services

The green issues concerning services are mainly to do with materials in terms of their embodied energythe total amount of energy it takes to make a material (or a building). See more on embodied energy, their manufacture and their reusability / recyclability. Also the question of dangerous emfsThe Electromotive force. This is the electrical force […]

Building Regulations

What are the regulations for?

See the English government web site on Building Regulations. Scotland, Northern Ireland and Wales are listed below. Slowly an increasing number of details in the regulations are diverging between the countries.

Building Regulations deal with whether the building is built properly and is safe and energy efficient etc.
