3 Report on results of feasibility study Country: Finland Project: Puuppola ( KOLU) hospital Customer: Jyväskylä rural municipality, facility management unit Provider of Feasibility Study: Asko Ojaniemi Subcontractor (if needed): YIT Kiinteitötekniikka Oy 1 Background The hospital is built originally 1940 and expanded on several stages -60, -80,-90 decades. The buildings are connected to heating plant owned and operated by outside company, heat is provided based on normal district heating tariff in the area. The heating network in the area belongs to the municipality. 2. Aims and ambitions with the feasibility study This target was selected for study, because the building is relatively old and no major upgrading has been done during recent years. Preparation of energy performance project, sampling and evaluating data needed for the tendering process The management of the hospital has been changed several times during the past decades and there was no clear understanding how is the energy performance of this facility compared to other similar facilities. There is major renovation under planning but that will be realised only after several years and it was intention to look for possibilities for energy savings in shorter run by utilising ESCO concept.. 3. Overview on step-by- step process First step is light feasibility study in order to find potential savings opportunities In case savings potential is found the customer will decide whether to proceed based on ESCO concept or should it be proceeded as own Choice between different procedures is made by the facility management unit. If ESCO concept is selected and no major own investments are required the decision lies with municipal technical committee. If it is own investment or major amount of funds are requested for other parallel investments the decision is by municipal council. Investment decision will be included in total budgetary decision process. ESCO-concept will shorter the decision making time and main advantage is in starting the energy savings earlier. 2

4 First feasibility evaluation will take 1-2 days including site visit and collection of data. The building owner will do the datamining according to consultant instructions. Service providers do also the initial feasibility evaluations on small fee or free of charge. Initial feasibility study may be followed by letter of intent or pre-contract where main terms of agreement are stated and also the process to full contract is described. After the letter of intent the energy consumption in interested areas are measured in detail and other issues like indoor climate is measured as reference value for final contract. It is important that the energy savings are not reached on the expense of indoor climate quality. 2 The acquisition process - Rural municipality of Jyväskylä was invited to advisory board and after first meeting the discussion has continued and reached the point that completion of few pre feasibility studies have been agreed - Quite large number of involved parties were present during the first site visit. Municipal facility management was present as owner representative and hospital technical personnel as tenant representative - These buildings are in need of renovation, ventilation systems are not up to present standards. - Main argument is that can something be done before these buildings will be under major renovation through municipal budgetary system. - At this point only municipal facility management organisation is involved in decision making, technical committee is informed. - The feasibility study expenses are divided between the project and YIT. Municipality is covering their own costs. - Datamining process Heat electricity and water consumption data for last three years were collected. All ventilation equipment were checked visually and main equipment data recorded.. Customer provided all energy consumption data and it is based on measured and invoiced values and can be considered reliable. Three years average is baseline, it can be corrected by whether data if past years have been exceptional. Data on existing heating and ventilation equipment was collected during the site visit. 3

5 3 Results from feasibility study Heat consumption Measured consumption MWh/a Reduced value for average year MWh/a Nominal 60 kwh/m3,a Heat distribution: -radiators 61 % -ventilation 29 % -domestic water 11 % The specific consumption was 60 kwh/m3 when the average in similar building at Jyväskylä latitude is 74,3kWh/m3 The consumption is on average level Electricity measured consumption MWh/a specific consumption 21,5 22,3 22,2 Specific consumption was 22,2 kwh/m3, when on average at similar facilities it is 30,3 kwh/m3. Consumption is lower than average. This is probably due to lower than present standard ventilation. When the buildings are renovated it is expected that electricity consumption will increase. Water Consumption m3 Specific consumption 358 dm3/m3 Average specific consumption at similar facilities is 278 dm3/m3 and this can be considered to be at normal level. The consumption of heat, electricity and water are on average level. During the site visit no such possibilities were found where EPC concept could be immediately applied in the buildings. The present ventilation system is decentralised with local controls. The newest part of the facility has heat recovery systems, the oldest part have only centralised ventilation out and replacement air is coming decentralised to each room. The construction of modern centralised air conditioning can not be covered by savings. In connection of major renovation the heat recovery unit investment may be carried out as ESCO service. The internal heat distribution network in the area is built in -70. The piping outside the heating plant walls belongs to the municipality and thus it is not heat supplier responsibility. The piping is technically in good condition but energy losses are higher than with modern piping. The present system consists of 4

6 mineral wool insulated pipes in concrete canals when modern pipes are polyurethane insulated pipes in plastics outer shell. The internal losses will be measured at later stage and esco project built to replace the piping if the replacement is found to be feasible. Weak point Measure foreseen Estimated investment Estimated annual cost Estimated Savings (kwh,co2, ) Static pay back time Ventilation major renovation no payback Heat piping Replacement Assumption 5% energy savings 50 MWh 25 years (to be confirmed after more detailed measurements) The heat recovery for ventilation can be carried out only in connection of other major renovation work. When air conditioning is improved it may increase energy consumption instead of decreasing it. The responsibility of heat distribution piping was unclear for many parties. This has been clarified now and the responsible party can pay attention to it Evaluation for the possibility of implementation of Heat piping was not the intention of the site visit but it came up in the discussions. The development will be followed and interested ESCOservice provider has been found. Energy supply is by outside company. Energy is produced by oil but the heat tariff is general district heating tariff and with present oil price the heating is not profitable business for the heating company. In case oil price stays this high for longer period, the heating company will replace the oil boilers with wood pellet boiler, they have done so in some other targets already contracting Please indicate the criteria you choose to justify your recommendation e.g. pay back time too long - The administration is advised to look for the possibility for ESCO services regarding heat recovery in ventilation when the renovation at the target will take place. Heat pipe heat loss measurement is recommended. There are heat meters in some of the buildings and in case these meters are found to be reliable the heat loss can be at least partly evaluated from the existing meter readings, must be confirmed by measurements. It is recommended to proceed with investment if the loss is found big enough to justify the investment. About 10 % savings would justify the investment. 4 Gained experiences and lessons learned 5
