Heavy Fuels

Atmospheric pollution is one of the most important environmental problems, becoming a phenomenon that could reach levels of serious consequences with irreversible environmental impacts. In Mexico, like in several other countries, brick makers carry out brick production by burning mixtures of different heavy fuels. Because of the wide variety of fuels used it is necessary to determine what types of residual gases are generated, in order to propose remedial treatments in production or to introduce substitution technologies. These preventive actions need to be put in place in order to comply with the Ecological Balance and Environment Protection General Law. Brick kilns emit pollutant gases and particles that remain in the air causing a serious health hazard to the near-factory residents. Amongst these pollutants are carbon monoxide (CO), sulfur oxides (SOx) and hydrocarbons. This paper presents the results of the analysis of a novel 3-kilns coupled system. This experimental analysis includes the determination of the combustion products for gases and particulate matter generated from the burning of the heavy fuels using Gas Chromatography and Scanning Electron Microscopy. Field data also allowed the determination of energy savings for this system, mainly due to the reduction of the consumption of fuel. Fortunately these results show a combined 30% energy savings and a reduction of pollutants and particle emissions.

Building Occupancy

Demand controlled ventilation (DCV) reduces energy loss by reducing the air exchange flow rate to the minimum required to maintain acceptable indoor air quality (IAQ). DCV commonly uses carbon dioxide (CO2) as a proxy for human activity and increases the ventilation rate once a preset CO2threshold is exceeded. Significant improvements over threshold based ODV strategies are possible if the natural infiltration rate of the building is measured and the occupancy schedule determined by analysing the CO2concentration continuously. These calculated parameters allow mathematical modeling of the ventilated space and the determination of future CO2concentrations and allow prediction of future ventilation demands. The natural infiltration rate and the onset and duration of vacancy periods in a residential dwelling were determined by analysing CO2concentration data. Concentration declines which fit an exponential decay curve with a correlation coefficient >0.90 identified all vacancy periods. The measured natural infiltration rate was found statistically correlated with average wind speed. A dynamic predicted occupancy map was constructed that has the potential to facilitate significant energy savings via deferred ventilation and intelligent cooling and heating strategies.

Time Determination

Methodologies have been developed to allow real-time determination of energy production and use as well as sizing of HVAC equipment based on thermal loads at the residential level. The data obtained reflect actual properties of the thermal envelope and appliance efficiencies, as well as actual renewable power production. The use of properly sized HVAC equipment introduces further energy savings. Recovery of energy savings expressed in terms of carbon offsets provides an incentive to improve the occupant’s energy footprint. When monetized, the energy cost savings and carbon offsets have financial benefits. These benefits are evaluated for model homes in various climatic zones within the state of California.

The Given

An attempt to use the base thermodynamics and exergoeconomic aspects of decision tasks of energy efficiency and energy saving with the examples of in heat-, gas- and watersupply in housing and communal services of Ukraine is presented. The methodology of forming the analytical dependences of account and payment of the got and used heat is presented as a result of this approach. This system of account has the followings advantages: 1) the sum of payment takes into account not only an amount but also quality of energy flows; 2) efficiency of work of all elements of this system is taken into account.  The operating presently system of tariffs on natural gas does not take into account current composition of gas and exergy of gas. Dependence, which takes into account the real exergy of natural gas which is supplied, is offered in relation to the minimum exergy of natural gas, which is foreseen DSTU. At forming of cost of water-supply in dependence for determination of sum of payment for water is suggested to enter a constituent, which takes into account the exergy of stream of water, which influences the amount and pressure of the given water. Realization in practice of the exergyeconomic going near tariffs on energy which is consumed in housing and communal services of Ukraine allows from single power positions objectively to estimate efficiency of functioning of all elements of the systems heat-, gaz- and water-supplys. It allows practically to carry out market approach to forming of tariffs on heat-, gaz- and water-supply and to mobilize producers, suppliers and users of services, in this sphere of housing and communal services of Ukraine on an energy-savings and energy efficiency. It is necessary to expect that introduction of these principles has social influence because it is a step which unites the citizens of Ukraine in the decision of tasks of establishment of transparent and just price policy of the state in housing and communal services of Ukraine and improvements of situations with ecology in our country.

The refurbishment of educational buildings usually involves a variety of measures aiming at reducing energy demands and improving building functionality to achieve higher living comfort. This paper aims to develop an approach for determination of comprehensive refurbishment strategy upon existing preschool buildings in Slovenia from the aspects of energy and economic efficiency. The main idea of the approach is to separate and individually analyse the investments into those related to energy efficiency improvements and those related to improvements of building functional quality through the step-by-step evaluation of individual measures. The proposed approach was applied on the case study of the existing timber preschool building in the city of Maribor. Generally, the highest energy savings are detected only in the case of combination of multiple renovation measures. Moreover, the economic indicators show low efficiency for almost all measures if they are treated separately. Additionally, the analysis reveals that certain measures are totally inefficient in terms of energy, yet they are highly beneficial from the viewpoint of building functional quality, which indicates the importance of the multi-perspective assessment of renovation process. The conclusions of this study can be implemented to similar building types and construction ages in similar climatic and economic environments.
