Positive aspects : Contemporary look, open plan ground

floor, good daylight provision, high ceilings, uniqueness of

lantern.

Negative aspects: lack of storage space, entrance sequence,

heating provision and controls, use of MVHR system

The Code for Sustainable Homes How it worksThe Code for Sustainable Homes

Its ambition is clear; guiding the design and

construction of sustainable homes to set

world class standards that reduce the impact

• At Level 6 there is a mandatory heat loss

parameter

• As a result the ratio of glazing to wall in the

Lighthouse is 18% as opposed to 25-30% in

traditional houses.traditional houses.

• This drove our decision to locate the living

space on to the first floor enabling us to

maximise daylight and volume, with a top-lit

double height living space.

Selective thermal mass

Phase changing material in the ceilings

absorbs the room heat by changing from solid

to liquid within microscopic capsules

embedded in the board. This process is

reversed when the room is cooled with the

night air, working with the passive system of

the wind catcher.

BRE Innovation Park 2007

Innovation – Raising the profile of Sustainable Design

The energy cost of running the Kingspan BRE

house would be about £31 per year for the house would be about £31 per year for the

wood pellets, assuming wood pellets cost 1.8

p/ kWh. The electricity is free, from the sun! A

house of the same size and shape but built to

2006 Building Regulations standards would

cost about £500 a year in energy bills.
