Executive Summary The area of focus is to help propel this design as a sustainable one by gravitating towards the usage of renewable energy and the reduction of consumption from main lines. Systems such as the rainwater harvesting system and solar panels will be integral in such intention. Additional elements regarding comfort will be seen as secondary. The primary focus beforehand will tackle the Solar radiation via Shading Mechanisms, Energy Saving Methods through Solar Panels, and the Ventilation through the means of Winged Walls.

SUSTAINABILITY ASSESSMENT ENERGY AUDIT The home uses 972kwh with meralcoâ€™s recent rate hike of 0.97 from February, the current rate now is 10.32 pesos/kwh 972kwh x 10.32pesos/kwh = P10031.04
OFF-GRID SCENARIO ANALYSIS In order for our structure to sustain itself, with 110% of required energy that is about 1069.2kwh/month, Photovoltaic panels had to be involved. Upon analyzing our structure’s rooﬁng, we realized that 47% (77sqm out of 163.8sqm) of the rooﬁng was directly under the sun path. In order to reach the desired 110% of the total energy used (1069.2kwh/month) we need to allocate 34.5sqm of the roof with solar panels.
*Given that: 1069.2 kwh/month31 daysis more or less 34.5 kwh/day (Required Area) x1000 watts solar energy x 20% efficiency x 5 hours of the day = 34.5 kwh/day Required Area = 34.5sqm
MATERIALS AND INDOOR AIR QUALITY
BOYSEN Paint contains Volatile Organic Compound(VOC). The tables shows the VOC content per liter in each type of paint or coating. In order to suppress or reduce exposure of VOC, the structure should increase its ventilation. The building is already well-ventilated with the number and arrangement of openings or windows in the structure. The volatile organic compounds used in the construction materials for the current structure. The paints used are eco-friendly The veranda can be the structureâ€™s designated smoking area. There are no sources of pollutants due to operations in the structure.
OPERATIONS WASTE MANAGEMENT
There aren’t technically any establishments in our building since it is purely residential. However, it still consumes resources which are Water and Electricity. In the renovation plan, the rainwater harvesting technology system will cover the water resource aspect. Wherein anything that doesn’t require potable water in the structure will use the water collected from the rainwater harvesting system. Meanwhile, the solar panels will supply the structure with Electricity. These aim to reduce operation waste without the need to implement policies onto the users.
The site of the project is located within a village that is surrounded and only contains residential dwellings. As such, all waste produced are municipal solid waste. To prevent oﬀ-site disposal, the users should be inclined to segregate and recycle.
BUILDING WASTE MANAGEMENT
The new construction may produce “industrial waste” upon adding roof and altering window designs. The renovation requirements meet sustainability targets of your structure by using recycled construction waste. Part of our renovation is to extend the roof in order to achieve the ideal passive horizontal shading aspect of our building. In order to achieve this, we are opting to use reuse some of the demolished roof parts such as metals, roof tiles, screws, and wood. If and only if they are in good condition, enough to beneﬁt the overall performance of our structure. There are no establishments in the structure that produce waste since the site of the project is inside a village.
CONSTRUCTION WASTE MANAGEMENT
Existing material standards are followed since the renovations we shall make involve ordering pre-fabricated elements. These are solar panels, rainwater harvesting technology, and vertical louvers for the windows. Installing these additions would not create much waste since majority of the wastes produced have already been done oﬀ-site. What are needed on site for these additions are mounting tools and adhesives. However, the roof extension would produce more waste since it involves demolishing a part of the roof for our intended extension design. We may opt to reuse roof parts that were taken out as long as they are in good condition and will contribute signiﬁcantly to our building’s overall performance. Any excess materials will be given or sold to junk dealers or recycling centers (if any exists in the Philippines).
Our group’s site is surrounded by other residential dwellings. Whatever disaster waste that may appear will likely be insuﬃcient for our structure. The exception is good quality wood that is salvageable and safe to reuse such as segments from destroyed furniture or even fallen trees. Most of our renovation is simply ordering pre-fabricated elements and technology to be installed on site. As such, recycled construction waste isn’t ideal for our goals. Although, if a convincing recyclable alternative opportunity comes we would surely consider it.
Simulated Green Rating Through the EDGE app we have simulated our green rating. The renovations we hope to do meet the EDGE standard which is a minimum of 20% savings in all the EDGE categories. Below is simulation results. ENERGY: 45.39%; WATER: 47.93%; and MATERIALS: 31.39%
INTELLIGENT BUILDING & AUTOMATION INTEGRATION ASSSESSMENT
Solar Philippines is the largest Southeast Asia solar company whose goal is making solar the least expensive source of energy and ameliorating world poverty. The cost is as low as Php 1,680/month. Solar Philippines oďŹ€ers packages that start at 1.3 kWp for customers with bills from Php 1,250 to Php 2,400/month. Whatever you currently pay your electric utility, you can now save to own a solar system in 3, 5, 7, or 10 years, and enjoy free electricity for the rest of 25 years, by signing up now.
The RainSava Indirect system oďŹ€ers the best in current pump technology, energy eďŹƒcient pump controlling, and reliability. Water is ďŹ ltered and collected in the main tank and pumped to the header tank where it is gravity fed to the appliances when needed. In the event that there is no water in the main rainwater tank, or in the unlikely event that there is a power cut, the mains water feed to the header tank opens mechanically to allow uninterrupted supply to appliances.
