A HYBRID WIND AND SOLAR SYSTEM IS A STRATEGY THAT OPTIMISES HIGH WIND SPEEDS OF THE COASTAL SITE. COMBINED WITH THE CLIENT’S PREFERENCE OF FRESH SEA BREEZE AND PASSIVE DESIGN STRATEGIES, A HYRBID SYSTEM WOULD BE ADVANTAGEOUS WITH A RENEWABLE, OFF-GRID SYSTEM.

Hybrid wind and solar systems can: - Lower your electricity bills by 50%–90% - Clean, renewable energy source without producing emissions damaging to environment - As solar and wind fluctuate annually according to specific times and dates, having both elements to produce energy increases productivity in generating electricity

The Ng’s are a couple planning to move to a site opposite the beach. The couple has no children, but does have two dogs. They often have guests stay, and like to throw fancy dinner parties. They both work for a solar power company. They would like their house to feel natural with lots of daylight. They like the idea of having sea breezes coming through their house and would like a house with really good passive design strategies. [Site 3 - Beach Suburb]

The Ng couple value a high-tech, efficient and powerful battery for an off-grid, hybrid wind and solar system. Dimmer switches, adjustable fan power are worthwhile investments for entertainment uses, particularly their interest in pop culture and latest technology.
AV. USAGE
AVERAGE W/M² L1 - 15W X 4 = 60W L2 - 9W X 10 = 90W L3 - 25W X 4 = 100W
L= 465.5w FA = 122.1 M²
L/FA = 465.5/122.1 = 3.812 W/M² MAX. W/M² = 5W 5w > 3.81W/M²
L4 - 9W X 11 = 99W L5 - 24W X 3 = 72W
Therefore the light usage is compliant and acceptable.
L6 - 12.5W X 2 = 25W L7 - 8W X 2 = 16W L8 - 3.5W X 1 = 3.5W
Thus, a 5kW battery system was chosen in order to fulfill higher energy demands for a standard household for 1-2 people (>3kW)

ANNUAL WATER CONSUMPTION THE NG FAMILY ONLY (2019)
If a mains supply water is readily available [Melbourne water], it is not recommended that rainwater is used for drinking or food preparation The volume of water utilised in the kitchen is the lowest of all household uses [health.vic]. Therefore using rainwater for purposes other than drinking and food preparation will still maximise water saving opportunities
RAINWATER SYSTEM
RAINWATER TANK CALCULATIONS Based on a 15-minute (x2) daily shower average time of the Ng couple, with the addition of gardening (twice per. wk), the daily water usage equates to 355L. Based on this figure, a 3000L water tank was chosen.
KINGSPAN 3000L UNDERGROUND TANK SPECIFCATIONS - 2940L x 1600W x 1200H -High grade quality polyethylene, 100% virgin grade material - For installation in land area or under-slab - AS/NZ 4020:2002 Australian Standard for Drinking Water - AS 1546.1 Septic Tanks
HOTWATER SYSTEM
DESIGN CHOICE/CLIENT - Adjustable riser - Multiple inlet /outlet positions - Lifeguard child protection system The Kingspan underground tank provides the Ng family with a rainwater harvesting system with a small carbon footprint, along with saving space for the greywater systems and gardening beds.

- Will preserve green space of the Ng family’s garden and backyards, as well as space for the couple’s 2 dogs. This also ensures maximised views of beach/coastal surroundings and pleasant landscape of the gardens - Tankless systems supply cleaner and fresher water; does not require maintenance of rust and dirt found in storage tanks
STORMWATER SYSTEM Stormwater is rainwater that is not captured by the roof/downpipes; it is captured at the site’s lowest drainage point and pumped back out for re-use. Stormwater should only be re-used for low risk activities [e.g. toilet flushing, gardening]. This recyclable water is interconnected as the greywater system - see A106 for further information.

PLAN @ 1:100
- CAPTIAL COST: High inital deposit, however radiant heating system ensures optimum air quality the Ng - COMFORT: The Ng couple appreci- family prefers, as well compatability with renewable energy sources ates natural ventilation and - ZONING: Zoning is possible, thus prefers maximised air from the coastal nature of site. Hydronic reducing energy bills heating panels provide clean, radiant heat; maximised quality ventilation without draft or dust
- OPERATIONAL COST: Low operational costs, as renewable energy inputs are utilised
- Simplified integration of hydronic heat pump; single step installation - High efficiency heating circuit pump, safety valve, 24L expansion vessel and emergency/booster heater are all integrated in compact design

UPGRADE SONNENBATTERIE STORAGE CAPACITY sonnenBatterie hybrid 8.1 : INCREASE IN ENERGY PRODUCTION During this time, the Ng’s have felt the rapid energy demand from the increase in energy bills, due to frequent energy production. The Ng couple both work from home, meaning utility and entertainment appliances must draw more energy, resulting in the need for an upgraded battery storage capacity.
TO OPERABLE CLERESTORY WINDOWS 2
The 5kW system has been upgraded to a 7.5kW off-grid system. It has been decided that the battery should be re-located to inside the home for increased convenience in usage frequency [also closer proximity to electrical switchboard and directly beneath solar wind turbine].

INCREASE OF NATURAL DAYLIGHTING
In an environment where a higher percentage of time is spent indoors in an interior setting, lighting is crucial towards a healthier, sustainable lifestyle. Daylighting or natural lighting through solar-powered skylights would effectively optimise visual comfort within an enclosed setting. As a residential design with a skillion roof, skylights are ideal in reaching a larger depth. The Ng couple would prefer natural daylighting to reduce energy bills, as well as maximise ambience.
2
RENOVATE TIMBER TRELLIS SHADING INTO SMALL GREENHOUSE The pandemic has caused a decline in public interactive experiences with nature; thus, a private green space would be highly valued during these circumstances, taking in consideration the enhanced appreciation for nature. As owners of a solar power company, installing a greenhouse design would drastically optimise solar gains for the recent spike in energy demands.

AFTER
OPERABLE CLERESTORY WINDOWS AND LOUVRE SYSTEMS INCREASE OF UTILITY FUNCTIONS
PLAN @ 1:100 Increased opportunities for adjustable ventilation and daylight control - maximised fresh sea breeze and air quality would be highly desired
As part of quarantine protocols, more time spent at home leads to an increase in home functions; as technology enthusiasts, the Ng couple would be interested in upgrading all louvre systems and clerestory windows to be electronically powered and adjusted by a single switch.
