A big welcome to our partner Satellite Architects. Leaders in sustainable architecture, Satellite will be contributing their cleverness and knowledge to this blog from here on in. So you can look forward to learning about greening the home from the experts, from passive solar to self composting loos!
Enough said, over to you Satellite…
Good Architecture
Satellite Architects has been recommending clients to use
Good Energy since the energy company’s inception. As a sustainable architecture practice we work hard to assure our projects tread as gently on the earth as possible. Now with an energy company we can recommend, we can offer a more thorough service to our clients.
Sustainability covers a broad number of issues related to buildings and each of our clients has its own focus and goals for engaging with sustainability. We have worked with a wide range of clients, from those whose goal is to be entirely self sufficient, to those who simply want to reduce their running costs.
Sustainability in buildings is a broad subject but can include: the systems used to heat, cool and light your home, how you supply and reuse water, where your waste goes, how you prevent heat loss and gain, where you buy your energy (Good Energy), the materials you put into your home and the labour used to build your home.
COST FREE SUSTAINABILITYThere are many things you can do to live in a more sustainable way that don’t have any additional cost. For example recycling food waste into garden compost or using public transport or walking instead of driving. In fact often the most sustainable choices can save you money and may
even earn you money.
Sustainable buildings aren’t always about new technology like solar panels, wind turbines and biomass boilers. Many heating and cooling issues can be solved with good design principles which have been used for centuries.
Passive solar designThe Romans positioned their houses and baths to face south installing more windows (Maybe 'openings' is better as I doubt they had Velux then!) on the south side, making maximum use of the sun’s heat and light.
Passive solar design uses the natural movement of heat and air to maintain comfortable temperatures, with little or no mechanical assistance. The point is to design the building to maximize the benefits of the sun using five basic solar design principles: orientation, overhangs, insulation, windows and thermal mass.
Stack effectSince ancient times the Persians have used wind towers and stack ventilation. A ‘badgir’ is the term for wind tower which is a tall chimney that expels warm air in the day and traps cooler breezes at night. When there is no wind at night, heat released by the tower walls warms the air creating an air density differential and a reduced pressure zone at the top of the tower causing an up draught.
(From the 2nd PALENC Conference and 28th Conference on Building Low Energy Cooling and Advaced Ventilation Technologies in the 21st Century, September 2007, Crete Island, Greece.)Stack effect is a natural way to cool a building avoiding air conditioning. Stack ventilation is temperature induced. When there is a temperature difference between two adjoining volumes of air the warmer air will have lower density and be more buoyant thus will rise above the cold air creating an upward air stream.
Limit WasteLimiting waste on your building site won’t cost you any extra and could save you substantial amounts of money. Currently, depending on where you live, you will pay dumping fees plus landfill tax.
SurplusUsing surplus building materials in another great way to save money on your building project and can be free if you are willing to pick up unwanted supplies. See

John is an old hand at solar generation - he's had a solar thermal system on his roof for the past five years which takes care of about 75% of his annual hot water needs. One of the first to join Good Energy's HotROCs scheme - which is funded by Good Energy Gas customers - he earns about £86 a year from us for the heat he generates, as well as saving money on heating his hot water.
