• W2736666118 abstract "Topic B4: Ventilation IMPACT OF INCREASING OUTDOOR VENTILATION RATES ON ENERGY CONSUMPTION FOR OFFICE BUILDINGS IN TROPICAL CLIMATES Donghyun RIM 1,* , Stefano SCHIAVON 2 , and William W NAZAROFF 1 Department of Civil and Environmental Engineering, University of California, Berkeley Center for the Built Environment, University of California, Berkeley Corresponding email: mcdhrim@berkeley.edu Keywords: Ventilation; Tropical climates; HVAC energy consumption; Energy cost INTRODUCTION Buildings in tropical climates consume a relatively large amount of energy for conditioning outdoor ventilation air compared to mild climates, mainly due to the warm and humid outdoor air conditions. However, providing sufficient amounts of outdoor air to occupants is a critical component of buildings. Several previous studies have found an association between low ventilation rates (< 10 L/s per person) and building-related adverse symptoms. Recent scientific studies (Sundell et al., 2011; Fisk et al., 2009) indicate benefits for higher ventilation rates, up to 25 L/s per person, for reducing building-related symptoms and promoting occupant health, satisfaction and productivity. Nonetheless, higher ventilation rates may require a significant increase in energy use, especially in tropical climates due to the additional energy required for treating warm and humid outdoor air. The present study estimates the potential energy consumption and cost of increasing ventilation rates for office buildings in tropical climates, considering Singapore as an example locale. METHODS Annual hourly weather data were retrieved for Singapore from IWEC (International Weather for Energy Calculations) data. The daily median outdoor temperature ranges from 24.1 °C to 30.0 °C for the whole year. The outdoor RH ranges from 68% to 98%, and the corresponding humidity ratio is in the range 0.17-0.21 kg w /kg da . Building energy consumption due to outdoor air ventilation was calculated as a function of ventilation rate (10-40 L/s per person), indoor dry-bulb set-point temperature (22 °C to 30 °C) and relative humidity (RH, 30-90%). The ranges of coefficient of performance (COP, assumed to be in the range 2-6) and electricity cost (Singapore dollar, S$0.20-0.40/kWh) were applied to predict ventilation energy cost based on current and expected future values of these parameters (Energy Market Authority of Singapore, 2013). Using these parameters, energy consumption was estimated by calculating specific enthalpy of moist air, sensible energy, and latent energy (ASHRAE, 2009). RESULTS AND DISCUSSION Figures 1a and 1b show monthly and annual sensible and latent energy demands to provide ventilation rate of 10 L/s per person for supply temperature of 23 °C and RH of 60%. The estimated annual sensible and latent demands for providing a ventilation rate of 10 L/s per person are 1660 MJ/person and 8230 MJ/person, respectively, indicating that a significant fraction (83%) of the total ventilation energy requirement is latent.
