Energy saving-Energy solutions for businesses



A medium size hotel in Greece, consumes more than half of its energy needs for domestic hot water. Despite the fact that we live in a relatively warm climate, our hotels consume more energy for heating than the rest of Europe. This of course means considerable expenses, air pollution from CO2 emissions and therefore negative contribution to climate change.
If one considers the ever increasing fossil fuel prices, especially oil prices and the economic crisis, energy saving becomes a vital factor for the running cost of the hotel.





















In places such as restaurants, bars or cafes, there are special conditions during their operation time. During the summer months, most of them work with the doors open, while all the appliances such as ovens, blenders, coffee makers work throughout producing a lot of heat, while the customers usually sit outside. During the winter months they work with the same appliances on, while the customers now sit inside. Both customers and employees must feel comfortable in both cases and so the right techno-economic solution for all year long.










Apart from the basic environmental need for energy saving, there is also the matter of economy. Legislation on a national and European level makes energy saving in buildings, apart from cost effective, compulsory.











The energy saving law for energy saving in buildings is the guideline for building rating according to its total energy consumption. Based on scientific and technical criteria which are the same for all buildings, the total energy consumption for heating, cooling, domestic hot water and ventilation is calculated and the results produce the rating of the building. The less the energy consumption, the higher the energy saving rating and vice versa. The energy consumption is based on theoretical calculations regarding position, geometry, insulation and heating, cooling and domestic hot water installations. The final three play a major role in the energy rating of the building.
The higher the building energy rating, the higher its market value. Every new or renovated building should fulfill certain energy standards which are implemented in the corresponding government guidelines and the energy saving legislation. For further information you can visit the official site of the Ministry of Environment, Energy and Climate Change.



Energy saving is not only based on the right choice of installations and building materials such as insulation, casings etc. The energy rating is also related to the fuel used to produce heating, domestic hot water and air conditioning. The use of gas (LPG- a mixture of butane and propane) for heating and domestic hot water, given a proper and secure installation by specialized staff, has proven a very cost effective solutions in houses as well as the tertiary sector. Our office, in collaboration with PETROGAS S.A. and always following the legislation and safety regulations, can offer you the choice of installing gas appliances in your property. You can come to us for further details on what’s prerequisite, advice and cost analysis of such an investment.












Heat pumps are devices that produce heat, domestic hot water and air conditioning to any building. During winter season, heat pumps produce heat and domestic hot water by absorbing thermal energy from the environment and release it into the building. The reverse process takes place during summer months when thermal energy is absorbed from the building and released to the environment. This is not a new invention. It’s actually based on the familiar process of an air conditioning unit that has been used since the beginning of the last century.

The advantages of heat pumps constitute:

a) Saving of up to 60% in comparison to a conventional gas/oil boiler.

b) The freedom of not having to buy or store any type of fuel (eg. oil tanks). Heat pumps use relatively small amounts of electricity, especially if the choice of the device is based on exact calculations and dimensioning. A heat pump with a higher COP will save even more energy.

c) Energy upgrade of the building

d) The purchase and installation of heat pumps in houses can be financed by European Funds. For further information you can visit the official site of the Ministry of Environment, Energy and Climate Change.

e) One more advantage is that a heat pump installation doesn’t necessarily mean that the existing gas/oil boiler should be uninstalled. They can be used simultaneously and the heat pump can contribute to energy saving thanks to the reduced time of boiler use.











Electricity generators or ac generators as they’re more commonly known, are used more and more frequently during the last few years in buildings that house small or large scale businesses (from restaurants to large scale hotels). The reason is simple: they offer independence from the public power grid and therefore can save the business from sudden power cuts or fluctuations that may damage expensive equipment. There is a great variety of ac generators and, as in most cases, one should be advised by people who have the knowledge and expertise in order to chose the right one for his needs. You can come to us to help you find the optimum solution that meets your needs.










When a wood burning stove is connected to the central heating of a house, there must be a way to insure continuous power supply. This is crucial because in case of a blackout, the water temperature should by no means exceed 100C and cause an explosion. One of the ways to prevent this hazardous situation is to connect a UPS in the domestic power grid. In case of a power cut, the boiler will continue to regulate the water temperature through ventilation regulation.










Our office can cover all categories of environmental studies according to current legislation.
