6.91 estimated at 5 kg, and the average mass of a litter, 5 kg. Average litter size was 3.5 so that average mass of a bunny was set at 1.5 kg. To determine the total contribution of these living occupants, a figure for their total population is necessary. From Section VI.11, the following figures are extractable to provide food sufficient for 1000 people: approximately 420 goats, 1000 doe rabbits, 3500 bunny rabbits, 775 egg-laying hens and 3000 broiler chickens. Table 6.5 sums the latent and sensible heat gains. A breakdown_for -the solar radiation input, P can inputsunlight, now be derived. The direct and indirect latent components of heat gain are subtracted from the total incident radiation and the balance of latent and sensible heat derived. This calculation is shown in Table 6.6. VI.10.3: Electrical Heat Gain - Sensible and Latent: The second source of heat gain to the interior of the colony is the consumption of electrical power. Table 6.E2 projects power consumption per person for the prototype. These values must be divided into latent and sensible portions in a manner similar to that of Section VI.10.2. Table 6.7 lists the distribution. Space heat is considered 100% sensible as the probable method is electric resistance heating. Electricity is also considered 100% sensible. Other heating for both commercial and residential uses certainly contains a latent component. Cooking is possible in all housing stock units as well as in several central restaurants. Residential uses include hot water heating, clothesdrying, cooking, refrigeration, and miscellaneous heating processes. Latent heat output for cooking appliances ranges between 10% and 60% of the total heat output (6.13). Electric appliances for water heating produce approximately 50% latent heat (6.14) (6.15). Electric hot water heaters produce little latent heat at the tank but a considerable amount at the tap. An overall figure of 35% latent is estimated. Refrigeration produces a small amount of latent heat estimated at 15%. Miscellaneous heat gain is assumed with a similar factor. An overall level of 40% is estimated for latent heat
