How to improve the HVAC system of the buildingAmong the tips that can be adopted by the hotel to achieve an efficient HVAC system include;Installation of n economizer: This is one of the simplest and lowest-cost solutions that would enhance the HVAC performance of the building. Through an economizer, mechanical cooling would be replaced by passive cooling in which the economizer lets in the cooler temperatures outside the building into the building[CITATION Hsi13 \p 398 \l 1033 ]. In so doing, the compressor as a mechanism of powering air is eliminated and the only energy requirement in the building is to move the air throughout the hotel. The air inside the building tends to be hotter than that outside the building due to the overproduction of energy and heat during operational hours.Reducing load capacity: load capacity is basically the cumulative cooling and heating used in a building and an increase in the load capacity negatively affects the running of existing systems. Some of the strategies of reducing the load capacity of the hotel would be;Installation of insulatorsSuch opening s as in the roofs, walls, pipes and ducts are a very integral part in the management of the energy performance of a building[CITATION Guy12 \p 897 \l 1033 ]. The tear and wear of these components of a building in most cases culminate in cracks and holes that permit escape ofheat from the building.Installation of window filmsThis aims at enhancing energy performance by keeping check of the heat from the solar that accesses the building from the window openings. It is estimated that up to 30% of the solar heat
gain in a building is through windows[CITATION Dav162 \p 166 \l 1033 ]. By using window films, up to 80% of such gains is absorbed and reflected back to outside the building.Upgrading the building to energy star certified office equipmentJust like lighting, old office equipment tend to generate as much heat hence the need to upgrade to better energy efficient equipment. Such equipment as energy star certified equipment is better ways of enhancing the energy performance thereby reducing the load capacity of the building. Maintenance of HVAC systemTo ensure the HVAC system is running as efficiently as possible, proper maintenance should be given a center stage[CITATION Guy12 \p 288 \l 1033 ]. The maintenance practice includes but is not limited to checking and tuning up the system before the beginning of every winter season. Checking for defective equipment and leaks in the coils, ducts, pipes and unit fittings so as to ascertain any anomalies and the most appropriate corrective measure adopted is as well as maintenance strategy. Just like any other equipment, boilers, chillers and other cooling and heating equipment also tear and wear with time and would thus require replacements. Heat transfer can be compromised in case there is accumulation of cleaning debris and dust in the ducts and coils in the HVAC system hence should frequently be removed[CITATION Jas09 \p 458 \l1033 ].Another way of maintaining the HVAC system is by regular change of the filters most appropriately after every month. Educating the workforce
The need to conserve energy touches directly on the bottom line of the hotel owner or the manager and this may not be to the knowledge of the employees of the facility. For this light, it is important that the employees are trained on the strategies that would enhance the efficiency of the building[CITATION Hsi13 \p 189 \l 1033 ]. The facility management may consider organizing a brief training for its workforce so as to impart in them such skills that would ensure best energy efficiency practices that would see the load capacity of the facility reduced.Scheduling a professional energy editAn audit of the HVAC system of the hotel would be important in enhancing upgrades of energy efficiency. The audit should be consistent with the age and parts of the system as well as the current condition of the unit. From the professional audit, simple fixes can be made without necessarily making new purchases.Purchasing a new HVAC systemThis would be the last option and should be done upon inspection and finding out that the systemmay need a replacement in order to work better[CITATION Mon161 \p 697 \l 1033 ]. This is through a check of the system’s Seasonal Energy Efficiency Ratio rating. If the rating is found to be less than 13, then an upgrade would be recommended. Implementation of controlsPreferences on how cooling and heating systems function can be set by the user of a space using controls in a way that they are running more efficiently behind the scenes. Demand and occupancy sensors, programmable thermostats and timing automation systems among other devices are among the devices that can be used as controls[CITATION Han11 \p 396 \l 1033 ]. These
devices utilize cooling and heating during busy hours as when as when the building is non-operational.Type of HVAC System usedThe type of HVAC system used in the hotel is split HVAC system. The various components of the system are located both to the inside and outside of the hotel building. Among the components of the system include air conditioning units, thermostat, ducts and evaporator coils. The outdoor unit of the system which is composed of the compressor, expansion coil, capillary tuning and condenser coil is installed near or on the external wall of the building. The indoor unitis made of a filter, cooling coil and a blower[CITATION Mic12 \p 429 \l 1033 ]. The system might have been adopted due to the following reasons;Its quiet performance: The components of a conditioner which produce sound are the fans and the compressor which cool the condenser. These components are located outside the building hence minimizing the levels of noise. By locating these components outside the building, the comfort levels of the hotel are increased. Location of the compressor and the fans outside eliminates the major noise sources in the room.It is efficient and cost effective: In as much as the initial cost of the installation of split HVAC system could be higher than that of a window unit, this system saves on energy hence relieving the facility owner significant energy bills as well as the durability of the system[CITATION Jac11 \p
