Contact person: Mr. Loris Naldoni

Type of geographical location: The lodge is located in the countryside, close to the borough of Brisighella (RA) in the Romagna hills, in the valley where the Lamone river flows. It lays in a farm of 10 hectares, at an altitude of 290 metres above sea level. The surrounding hills reach a maximum 650m height, not determining shadows on the farm area. It is a sunny and windy area.

Kind of lodge’s facilities: The lodge is composed by two buildings of two floors each, obtained in 2001 by completely restoring a rural old house and a near barn. They provide tourist accommodation, restaurant service, mountain bike renting, horse riding, reading room and video room. They also produce and sell to the guests farm wines, cold cuts, sausages and ham. The farm may also accommodate groups (max 15 people) participating to companies refresher courses, education-tour, sport teams supplying, on demand, private rooms for work.

LODGE’S DESCRIPTION

Operation regime: Open all year

Number of rooms: 6 Number of beds: 12

Hospitality consists of 6 bedrooms (2 beds each), 2 in the main building (E1) at first floor with common toilet. The other four are located in the second building (the old barn E2): they are equipped with private bathroom, TV, telephone, sound broadcasting, heating and conditioned air.

The main building hosts at the ground floor the restaurant (50 seats), a big kitchen, a reading room and video room. The flat of the lodge owner is located in the main building at the first floor.

Occupation level: 40%. Guest staying does not have favourite periods and cover a growing demand for numerous targets, including business activities. Nevertheless the main target remains people looking for short relaxing weekends, but also for the standard week holiday. The lodge is always full during weekends (Friday and Saturday nights); during the other periods it has an average occupation rate of 1 out of 6 rooms.


Constructive characteristics:

The main building is of 150 sqm at the ground floor and of 120 sqm at the first floor The second builging is of 90 sqm per floor. Total area .450 sqm

During the complete restructure of the buildings attention has been put to the details and to the materials. Local stones, hand made bricks and pantiles, bricks from Tuscany, ceilings with wooden trusses, heart–wood doors and frames are the raw materials of a restructure whose main aim was the maintenance of the original or typical architectonic elements of the local tradition.

The old stone walls of the buildings are very thick: 45 cm minimum.

Windows, defined in the past, have different size and are mainly small. They are provided with double glasses and wooden casings. In general the buildings are well insulated,

Main entrance is south oriented, in both cases. The main building presents a large open portico on the south and west sides: it serves as dining and rest area in warm periods, especially in summer.

Roofs are made of hand made pantiles, have a 30° slope and are south-north oriented.

The two buildings are close but sufficiently distant not to shadow each other.

All the illuminating elements have been studied to find the tastes of the antique materials and to create evening relaxing atmosphere. Outside, small brass lamps have been installed and run along the entry path and the adjacent green areas. Ground lights enhance the secular mulberry-trees, lamps set in the river stones walls draw the ways of the avenues and of the paths. All outside lamps are lof low consumption type ( 9W each).

Most of the inside lighting is dominated by materials like wrought iron, glass, copper, pottery in order to give to each room and bedroom a touch of originality and at the same time an element of coherence with the whole environment. All inside lamps are normal incandescent lamps (mostly 60 W each).

Space heating and domestic hot water production are provided by 3 LPG systems ( one for

Contact person: Mr. Sergio Lodi

Type of geographical location: The lodge is located on the mountains, within the green of the Alto Frignano Park, at an altitude of 1220 metres above sea level. It lays in the heart of the Appennino Tosco Emiliano, very close to the Mount Cimone sky station. It is a windy and quite sunny area, surrounded by 50 hectares of fields and forests.

Kind of lodge’s facilities: The lodge is composed by two separate buildings, obtained in 2002 after the complete restructuring of some rural houses of the eighteenth century. A new wooden building has been recently established to host the farm dairy, a stall for horses, a laundry and the rooms for the new wood chips boiler and related wood and chip warehouse. The lodge provides tourist accommodation and restaurant service. Beside to the main building a children playground has been arranged. They arrange walks and trips to the surrounding valleys, horse riding and rent mountain bikes. They also produce and sell to the guests cheese and jams.



Number of rooms: 12 rooms + 3 mini-flats Number of beds: 30

Hospitality consists of 12 bedrooms and 3 mini–flats, provided with private bathroom. Each mini flat includes also a dining room with a kitchen corner. The main building hosts all the mini-flats, 4 guest rooms and all the service rooms: the reception hall, the restaurant (50 seats), a large bar, the kitchen, and the private flat of the lodge owners. The second building is 500 m far from the main one, in a higher position, and hosts the remaining 8 guest rooms.

Occupation level: 30%. The lodge is always almost full on Saturday nights, national and religious feasts- especially Christmas and Easter- and during the whole August month. The short distance to sky stations , paragliding schools and lakes for fishing favours the accommodation of national and foreign guests looking for places suitable to practise sports in the open air.



The main building has been obtained by joining and restructuring two antique farm houses, taking care of preserving the architectonic original style and choosing construction materials according to the local traditions, often recovering parts coming from other old buildings. Also the simple rustic internal decor was intended to maintain the warmth and atmospher of the past.

The main building is composed of 3 floors of about 110 sqm each. The ground floor is partially underground -on the north side- due to the natural slope of the ground.

The old stone walls are very thick: 50 cm.

Windows have different size, but they are mainly large - especially in the restaurant rooms. They are provided with double glazing glasses with internal wooden shutters.

The roofs are made of stone tiles with a 30° slope, oriented respectively to north-west and south- east

The second building can be reached going up to the mountain for 500 m along a narrow street. This isolated building, with the forest at its back, is composed of 2 floors of 80 sqm each. It hosts 4 guest rooms per floor, with separate entry points and a kitchen available for everybody. Also in this case teh building was obtained by restructuring an antique house with very thick walls and roof made of stone tiles, south –north oriented. Windows on the contrary are quite small and they have been equipped with double glazing glasses with internal wooden shutters.

Both external and internal illuminating elements of the whole lodge make use of incandescent lamps (40-60 W each).

Total squared meter ( area to be heated): 650 sqm (330 sqm main building, 180 sqm secondary biulding, 140sqm new facility)

ENERGY DEMAND

Electric energy






Electric energy is necessary to power all lighting systems and the following machines and appliances: 3 freezers, 3 refrigerators, 1 dish machine, 2 wash machines, 1 dryer, 1 pasta machine and 1 milking machine.


Thermal energy

Annual average consumption: 170000 kWh


Such consumption, necessary to provide space heating, domestic hot water production and for cooking, was obtained up to 2002 by boilers fuelled with LPG. In that year the average annual fuel consumption was about 12000 Euro (10500 Euro just for the space heating and DHW production, corresponding to a rate of fuel consumption per square meter equal to 230 kWh/sqm).

High values of thermal energy consumptions depend on the location on mountain in a windy area, requiring heating system operating from September to May. Moreover during winter it is necessary to maintain a temperature of at least 15 degrees in the guest rooms, to be able to reach in few hours a comfort temperature for clients not used to book with large advance.

In 2003 the lodge owner decided to replace the LPG system with a remote control heating system that works with a boiler fuelled with wood chips. This system provides heating to all the Lodge buildings and makes use of wood mainly supplied from the rich woodlands in the boundaries

Average annual wood consumption varies from 0,6 to 1Ton depending on the quality of the wood(humidity percentage)

Wood cost per year (in case of wood not self produced): 4500 Euro

The total investment for the provision of the new boiler ( power 85 KW) and related equipments (pipelines, accumulator, control system, distribution system, chips warehouse), installation works and accessories (chop machine, wood track) was about 98000 Euro, that are expected to be fully recovered in 10 years.

IMPROVEMENT ACTIONS


• Replacement of traditional lighting devices with high efficiency lamps


• Instalment of 30 sqm of photovoltaic cells system (4,5KWp) for electric energy production. Panels with 30°slope south oriented can be allocated in the field close to the main building.

• Instalment of a wind–power plant of 33kW, to be set at a distance of 300 m far from the main building and 500m far from the second building.

These kinds of measures, taking into account the existing incentives in Italy, can be summarised through the following table:

Type of geographical location: The lodge is situated in the Comacchio Valleys, within the Delta del Po Natural Park, close to the Adriatic Sea coast. It is an area formed by water expanses covering more than 13,000 hectares, where lagoons are crossed by banks and spotted with hills. The lodge lays at 2 meters under the sea level, in the inner wetlands. It is a sunny and humid area.

Kind of lodge’s facilities: The lodge is composed by 3 rural buildings, obtained in the nineties by restructuring some ancient stone-houses. They provide tourist accommodation offering guest rooms, mini-flats, bungalows -available also for animal hosting- and a camping area with common services. The lodge includes a restaurant for a maximum of 80 people. They produce and sell to the guests farm cheese, sausages, honey, jams and home made pasta. They practice horse, ovine and fish breeding and are renowned as bird watching info-point. They also act as Didactic farm and are available for arranging horse riding, bicycle and walk tours and fishing activities.



Number of rooms: 8 rooms + 2 mini-flats Number of beds: 14 in the guest rooms + 8 in the mini-flats.

Hospitality consists of 8 bedrooms (2 single bed+ 6 double bed) located in the main building (E1), 2 mini-flats, situated respectively in the other 2 buildings E2 and E3, 3 bungalows without heating system and a camping area with 8 sites equipped with electricity and a common service area with toilets and wash basins, located in the building E2.

Occupation level: 40%. The lodge is always full during the favourite periods for bird watching, namely from March to May. In the other periods of the year it is full mainly during weekends (Friday and Saturday nights). Guests are both Italian and foreign people, mainly looking for a relaxing place, to get in close contact with the local natural environment.


All the buildings of Prato Pozzo have been obtained by the complete restructuring of rural farm houses, built many centuries ago. Restructuring took care of respecting bio-architecture criteria, making a large use


of natural materials like wood, cork and marsh sticks. Moreover, exploitation of renewable energy sources for electricity and heat production have also been taken in serious consideration.

All the buildings have old stone walls which are 45 cm thick and are covered by airy roofs made of tiles, having a 30° slope. Windows are mainly large and equipped with simple glazing and wooden casings and shutters.

The main building E1 is composed by 3 floors of about 110 sqm each. It hosts all the guest rooms and the private rooms of owners. Along the northern and western sides of the building a veranda has been created, hosting a restaurant with 80 seats. Main entrance is north oriented and provided with a inner door.

Both the other two buildings are composed of 2 floors and present an open portico on the south and west sides. In both cases the ground floor is larger than the first one.

The second building (E2) hosts a mini-flat of about 150 sqm, with a dining room at the ground floor and 2 bedrooms plus a bathroom at the first floor. This building at the ground floor hosts also a laundry room, a room for ceramic workings and all the camping common services, including 16 toilets.

The third building (E3) hosts a mini-flat of about 160 sqm, with a dining room and 2 bathrooms at the ground floor and 3 bedrooms at the first floor. This building at the ground floor hosts a stable for 10 horses.

All the illuminating elements make use of high efficiency lamps.

ENERGY DEMAND

Electric energy





Electric energy is necessary to power internal and external lighting systems and the following machines and appliances: freezer, refrigerator, wash machine, 2 electric ovens, oxygenator system for fish breeding, heat pump used integrated with the solar thermal system.


Thermal energy

Space heating in the main building is mainly provided by a wood burner fireplace, consuming about 2 qt of wood per day, and operating for about 200 days/year. Wood and vegetable wastes can be quite easily found free of charge in the local area, thanks also to agreements made with local forest owners.

Wood is integrated with solid fuel bricks - favouring heat keeping- with a cost of about 6 Euro per day.


Domestic hot water in the main building is provided by a solar thermal system, using 6 sqm of solar collectors mounted on the south-oriented side of the roof. These collectors are integrated with a heat-pump system, allowing to reach the desired water temperature also in absence of sufficient solar radiation.

Further more at Prato Pozzo there are 3 LPG boilers with individual gas storage tanks:

- 1 wall hang boiler (power 35kW) to integrate solar hot water and biomass space heating systems in building E1;

- 1 wall hang boiler (power 24kW) providing space heating and hot water production in building E2; - 1 floor hang boiler (power 24kW) providing space heating and hot water production in building E3.




Fuel cost: 0,5 Euro per liter

Fuel consumption per square meter: = 70 kWh/sqm

IMPROVEMENT ACTIONS


• Instalment of 80 sqm of photovoltaic cells system for electric energy production (10KWp). The solar panel could be installed on the south oriented side of the main building roof. This action has been included in a project approved by the regional authority and should receive an incentive covering about the 40% of the total investment (being of about 54000 Euros).

• Introduction of biomass heating system serving buildings E2 and E3. A wood burner of 40kW power is proposed. In this case existing Italian incentives for energy improvement actions allows to recover in the medium period the 36% of the investment.

It lays in a farm of 5 hectares from where you can see the Santerno Valley, about 50 km far from Bologna. Land in this area is characterised by calanques and the “Vena del Gesso” (Chalk Vein) which are very interesting from both the landscape and the geological point of view. The air is refreshing in the autumn and spring, and pleasant in the summer.

Kind of lodge’s facilities: The lodge is composed by two buildings, obtained in 1995 by completely restructuring some rural stone houses of the eighteen century. They provide tourist accommodation, restaurant service, mountain bike renting and horse riding. There is also a play area for children, bowling green and walks for spotting deer. Finally they cultivate cereals and fruits and produce spirits, liqueurs, jams, honey and cookies available for their guests.


Operation regime: Open all year, apart from one month during winter, from Epiphany to S. Valentine.


Hospitality consists of 4 bedrooms with private bathrooms: 2 double rooms and 2 rooms with 4 beds each. 2 rooms are situated at the first floor of the main building and the others in the near “dependance”. By the end of 2005 a new renovated building will be available to host further 18 persons, offering 6 new rooms with cooking corner and private bathroom.

The main building hosts at the ground floor the restaurant (40 seats), a big kitchen, and a laboratory for jam production. The mild climate of the place does not introduce air condition need.

Occupation level: 30%. The lodge is mostly full in during the months of July and August and during weekends (Friday and Saturday nights) from April to October, with an average occupation of 110 days per year.



The main building E1 is composed of two floors of 90 sqm each plus a partial underground floor, hosting the cellars and the restaurant toiles (this part of the lodge is not provided with heating devices).

The second building E2 is composed by 2 floors, with one room of 16 sqm each.

The whole green lodge has total area of 210 sqm.

The old stone walls of the buildings are very thick (60 cm) and have been obtained with two rows of stones joined with sand and mortar and finished with stucco.

Roofs are covered by bent tiles put over a layer of polystyrene, in order to level up and to insulate the pre-exhisting roofs.

Windows, defined in the past, have different size and are mainly very small. They are provided with double glazing and wooden casings and shutters. In general the buildings are well insulated.

Main entrance is south-east oriented. The main building presents a large open portico on the south-east side: it serves as dining and rest area in warm periods, especially in summer.

The two buildings are close to each other, moreover roofs orientation, the slope of the ground and the trees in the nearby do not favour an optimal use of the roofs for the instalment of solar panels.

The rooms have been refurbished respecting tradition with 1900 country style furniture.

Also the illuminating elements inside the lodges have been studied to enhance the tastes of the antique materials and to create relaxing atmosphere. They adopted incandescent lamps in the bedrooms and halogen lights in the restaurant. Only outside lamps are of low consumption type.

ENERGY DEMAND
