Evaluation of European energy behavioural change programmes

This article is based on the findings of the BEHAVE Project (Evaluation of Energy Behavioural Change Programmes) which was supported by the European Commission under the EU Intelligent Energy–Europe (IEE) Programme. The project started with a review of behavioural theories and their applicability in the development and evaluation of energy-related behavioural change programmes, progressed to a case study analysis and finished with a publication of guidelines for programme developers and policy makers. This paper concentrates on the results of the case study analysis and the recommendations arising from it. In the case study analysis, information was collected on almost 100 cases aiming at behavioural change in energy use from 11 European countries. More detailed information was collected on 41 cases which were subject to meta-analysis to identify success factors and weak points and to gather information on the current evaluation practices in such programmes. The meta-analysis was carried out in five phases: context (pre-planning), planning, implementation, monitoring and evaluation. Planning and evaluation were recognised as two of the most critical phases. Many of the programmes operated with quite formal plans but were typically not based on scientific theories or evidence. In many cases, there was lack of market segmentation; the goals were not targeted and the programmes tried to offer “everything to everybody”. A multitude of ex-post evaluation methods for programme impacts were reported ranging from participant surveys, testing and comparison with control groups to top–down method evaluating the impact of several programmes focusing on the same target group. Process evaluation (25 cases) was slightly less common than impact evaluation (29 cases). Evaluation of the cost-effectiveness of the programmes was a rarity, most likely due to difficulties in quantitative impact evaluation.     

Evaluation of a participatory ergonomic intervention process in kitchen work

We evaluated a participatory ergonomic intervention process applied in 59 municipal kitchens. In groups of three to five kitchens, the workers participated in eight workshops, and generated and evaluated solutions to optimize musculoskeletal load in their work. An ergonomist initiated and supported the process. By the end, 402 changes were implemented. Evaluative data were collected using research diaries, questionnaires, and focus group interviews. The intervention model proved feasible and the participatory approach was mostly experienced as motivating. The workers’ knowledge and awareness of ergonomics increased, which improved their ability to tackle ergonomic problems by themselves. The changes in ergonomics were perceived to decrease physical load and improve musculoskeletal health. As hindering factors for implementation, lack of time and motivation, and insufficient financial resources were mentioned. In addition, the workers expressed a wish for more support from the management, technical staff, and ergonomists.     

Improvement of sanitation conditions in the liberated Croatian regions after the "Storm" campaign--the Lika-Senj County example

More than 6,000 sq km of the central and southern areas of the Republic of Croatia were liberated by the Storm campaign, August 4-7, 1995. On August 8, 1995, the Ministry of Health sent expert teams to the newly liberated areas, in order to ensure the basic conditions for the displaced persons to return and live there. To describe the public health measures taken we used the example of the Lika-Senj County (3,746 sq km and 71,215 population). Until October 1, 1995, 50 bodies, killed in action, were detected, pathologically and forensically examined, and then buried. Two hundred and thirty-three mostly elderly and sick persons were admitted to the reception center in Gospi?; 93 of them returned to their homes, 133 were accommodated with their relatives and friends, and seven were referred for treatment (four of them died). Two hundred and ten cattle carcasses were buried using adequate sanitation measures, whereas 5,575 sheep, 3,138 head of horned cattle, 298 head of hoofed animals and 300 head of other cattle were caught alive. The procedures of disinfection, disinfestation and disodoration were performed in 720 apartments, 2 hotels, 3 schools, one kindergarten, one health care unit, one sports hall and 5 shops. The main water pump was cleared of mines and partially repaired, whereas some 20 water supply objects were placed under surveillance. Three food depots were found and properly treated. The entire territory was closely observed for a possible occurrence of infectious diseases.     

A behavioural model of temperature controller usage and energy saving

Temperature controllers are typical devices in most office-buildings, but the intended users very seldom use them. It has been a constant observation during our research that all common temperature controllers to date are quite impossible to use and understand correctly. With the proper use of temperature controllers comfort could be improved and a lot of energy could be saved. This paper presents a model of first use of an OOBE device, in which the actors beliefs are included. A list of conditions for energy saving actions, a design decision matrix and a model of action circle is presented in this article. The model indicates that the users action can be extinguished at various points during the action circle. However, sufficient and understandable initial feedback on the devices interface is the key to correct novel use.

Effect of nitrapyrin on nitrapyrin residues and nitrate content in red beet roots fertilised with urea

The effect of nitrapyrin [2-chloro-6-(trichloromethyl)pyridine] application on nitrapyrin residues and nitrate content in red beet (Beta vulgaris L. var. conditiva) roots and in soil fertilised with urea was studied during the 1977 growing season. The nitrapyrin residues in roots were on 15 August between 0.00–1.19 μg g^?1 and on 1 October between 0.00–0.45 μg g^?1 (dry weight basis) correlating significantly r = 0.99, P<0.01) to the rates of nitrapyrin applied on 8 June (0–34 kg ha^?1). The content of nitrapyrin in roots decreased in autumn having in August-September a ‘biological half-life’ of 3 weeks. In soil the same parameter was in July-September more than 4 months. The ratio of nitrapyrin to its main breakdown product varied in soil between 3.5–24.8 and in red beets between 0.6–1.4. Neither of these compounds were found in processed canned red beets. Nitrapyrin treatment decreased the nitrate content in both soil and beets. The inhibitor application of 18 kg ha^?1 caused the highest reduction of the NO₃-nitrogen content in beets, the average values on dry weight basis being 0.51–0.34 mg g^?1 for 0–18 kg ha^?1 nitrapyrin application, respectively. The reduction of NO₃-nitrogen in beets from its level of 15 August to its September level was 44%. After 5 September the reduction of the nitrate level in beets was not significant.
