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.
