Low-E- Glass

 

  • Some of the energy is absorbed by the glass as it passes through. The absorbed energy heats the glass. The energy that has entered the living space is also absorbed by the items in the room such as furniture and carpets. These items also get warmed by the energy.
  • Warm items re-radiate the energy and this includes fires and radiators within the room as well as the warmed furniture. This re-radiated energy is no longer short wave radiation so the energy now travels back towards the low-e window as long wave radiation.
  • The low-e glass does not let the longer wavelength radiation emit from the coated low-e surface and is an effective reflector. The energy that has entered the room and the heat energy that was already present is reflected back from the low-e glass. Even the glass that was heated by the energy passing through it emits long wave energy and it can send it in two directions. Some is sent back out into the atmosphere and some to the inside of the building.
  • The result is a neutral appearance glass that lets energy in and helps prevent heat getting out.

Rain Water Harvesting

Rain water harvesting is an effective way to reduce the dependence on mains supplied water and reduce metered water bills. Rain Water Harvesting captures rainfall and stores this water in discrete storage tanks that can be called upon for a vareity of uses such as washing machines, gardening, toilets.

This type of technology is available with all Nest & Invest houses.
We are able to source and incorporate this at the time during the design.

Structured Insulation Panels(SIP)

Structural insulated panels (SIPs) are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are typically made by sandwiching a core of rigid foam plastic insulation between two structural skins of oriented strand board (OSB) to produce a rigid structure.

Sun tubes

Sun Pipes provide a novel way of capturing natural sunlight and reflecting it inside a tube to channel it into darker areas. These units are mounted on the roof or where there is a line of sight fof the sun, and can be used to provide a diffused source of free ambient light to dark room on any floor, including basements.

Triple Glazed Windows

This type of technology is available with all Nest & Invest houses.
We are able to source and incorporate this at the time during the design.

Installing double glazing can cut heat loss through windows by half. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.

Eco Underfloor heating for EcoBuildings

Swedish heat pumps underfloor heating system for buildings and garages for our eco buildings. Eco Underfloor heating systems suitable for cozy houses, and clearance of snow on terraces,drives,walkways.  Engineering systems which we can include in our buildings in colder climes.

HEAT PUMPS

Ground heat pumps take advantage of the temperature difference between ambient air and that of the ground a few meters below the surface to create heat energy. Water is pumped through underground pipes, and a heat exchanger is used to extract the extra energy due to this temperature difference. For every unit of energy you use in this process, you get about 3-4 units back.

SOLAR TILES

The latest in Solar and now very popular are Solar Tiles.

As solar tiles form part of the roof, they are much better at blending in meaning they are often considered to be less obtrusive than traditional solar panels.

Photovoltaic Energy Cells

With a photovoltaic system you can produce electricity from daylight through a process called photovoltaic’s (PV), even on cloudy days. With a 10 square metre collector area, around 900 KW per year of electricity can be generated. This quantity is equivalent to approximately 25% of the consumption of a 4-person household.

Solar Heating

Most of the average household’s energy use goes into heating water, including radiators or underfloor heating. A source of free hot water to use instead of commercial energy can make a dramatic financial saving. Solar Water Heating is the renewable technology of choice for most households as it offers a quicker payback.
