Over the course of today you will hear many definitions of sustainable development but possibly the most to the point is that coined by the Brundtland Commission. The BC, originally named the World Commission on Environment and Development was convened by the UN in 1983 to address growing concerns about the accelerating deterioration of the human environment and natural resources. The Commission was concerned with how sustainable development might be managed on a world wide basis with consideration given to inter country interaction on the issue given differing levels of social and economic development. And so Sustainable Development is ..... Ultimately the concept of ‘sustainable design’ suggests there is an onus on us all to make ourselves aware of how best to direct those who will build towards ensuring that we as humans remain in a state of equilibrium with our environment.
Areas to consider under the banner of sustainable development are for example modes of living, ie the development of eco villages, sustainable cities. Food production, how we can ensure replenishment of the soil through crop rotation, resting land strategies and so on. Work practice, particularly pertinent today and most specifically areas such as sustainable architecture. How we as individuals consider our ongoing use of natural resources, how can we impact imrprovements in consideration of energy usage, food packaging. New Technology, playing a significant role at the simplest level new forms of low energy lightbulbs through to sophisticated building management systems and of course somewhere in between renewable energy solutions.
There are many areas to consider when promoting sustainable design, however let’s look at how this might be done through the medium of renewable energy. OK, so what is renewable energy? These are a number of examples of renewable energy, and in particular we are interested in micro renewables such as heat pumps, solar thermal and PV, Biomass.
The heat pump is a particularly obvious form of renewable energy albeit this assumes a number of things including good practice in the design, install and commissioning of. Get these right and the heat pump as we will demonstrate is a particular effective form of sustainable living.....
A significant advance through IDM R&D has been the introduction of the new Navigator control system. A truly intelligent unit has a host of features designed to get the best out of the space heating abilities of the heatpump whilst optimising the production of hot water. Additionally the Navigator takes into account variables such as external temperature conditions and trends predicting heat requirements into the future thus optimising energy usage say in terms of utilising low tariff electricity. Furthermore the Navigator enhances consumer control of the unit with the entire system being controllable from your office desk! Unlike heatpump controls generally the system is intuitive with for example „party setting“ designed to interupt the normal day to day operation to allow for a sudden one off change in usage
Of course the IHS system allows for the integration of all forms of renewable and traditional systems as and when they might be required in the future. The thermal store being the central focus of our systems allows for the storage of all energy and ultimately the distribution of the energy to where it is needed to maintain maximum comfort for those relying on the system
Bei einem errechneten Stromverbrauch von 32.000 kWh p.a. ergibt dies eine Jahresarbeitszahl von 5,68. Die thermische Sanierung umfasste 2 Maßnahmen: Vollwärmeschutz Grundwasser-Wärmepumpenanlage Ein wesentliches Ziel dieser Sanierung war auch die Erneuerung des Heizungssystems und die Reduktion des Energieverbrauchs.
