A housing complex needs to think about how the community lives in it. Using the five principles of wellbeing in designing, thinking about sustainability with CLT as a low-carbon sustainable material, and community food security when disasters occur (such as Covid-19) with urban farming.

SUSTAINABLE HOUSE CONCEPT
The construction of modular housing is a solution to minimize construction time and material waste so that it can be an effort to support reducing the carbon footprint in construction. Sielti housing is campaigning for housing made from CLT (Cross Laminated Timber) processed wood which is stronger, resistant to disasters in Indonesia such as earthquakes, and minimizes the impact of fire, and more sustain. According to research, CLT is able to reduce the potential for global warming by 26.5% in the construction sector compared to conventional materials [1]. Apart from supporting sustainability, the impression of a wooden residence is also a innovation in urban areas so that users can be more relaxed when they come home from work with the presence of natural elements.

Prefabricated modular: requires fast installation time, minimizes carbon footprint in construction, reduces overhead costs
Due to its fire resistance, unlike steel, CLT remains structurally stable when exposed to high temperatures.
CLT can handle seismic activity because its flexibility is resistant to earthquake shocks.
Sustainable: made from production forest wood and fabricated to be more durable and resistant

HEALING BY PLANT
Urban people are always stressed with their work and want healing in the countryside
Providing a village plantation atmosphere for healing and producing secondary food needs
However, because city residents are always busy and don't have time, community gardens are created
URBAN RESILIENT CONCEPT
SURVIVED BY PLANT
some emergencies, such as pandemics, cause lockdowns
Urban farming within the area allows residents to use it as a temporary food source they can survive with the concept of food security
Through urban farming at zero GSB and front gardens managed by gardeners, agricultural products can be utilized together.

ENERGY CONSUMPTION PREDICTION
• 10 LED lights are turned on for 12 hours (from 18.00 to 06.00). So, the total electricity usage from these lights per day is (5×5 watts x 12 hours) + (5×10 watts x 12 hours) = 900 watts.
• LED TV (24 inches) in the main bedroom is on for 4 hours per day. So, the total electricity consumption for the TV is 35 watts x 4 hours = 140 watts.
• LED TV (43 inch) in the living room is used for 6-7 hours per day. So the calculation becomes 75 watts x 6 hours = 450 watts.
• Electric irons are usually used for 2 hours per day. So, the electricity consumption for the iron is 350×2 = 700 watts.
• Refrigerator energy efficient runs 24 hours a day. So, the electricity consumption for the refrigerator per day is 130×24 = 3,120 watts.
• Washing machine is only used for 2 hours per day. So, the electricity consumption for the washing machine will be 250×2 = 500 watts per day.
• Water pump is used an average of 2 hours per 2 times. So, the electricity consumption for the water pump is 200×4 = 400 watts.
• Rice cooker are used to cook rice in the morning and warm food in the evening. So, the way to calculate the electricity consumption of a rice cooker is 350 watts x 1 = 350 and 77 watts x ½ hour = 38.5 watts per day.
• additional: ceiling fan (if the air reaches a hot temperature of more than 29 degrees Celsius) 180 watts/hour, then if it used on 5 hours/day, so it will consumed 900 watts per day x 4 rooms= 3600 watts per day
Total 9.848,5 watts/day
