What the basic Net Zero Energy Building Terms used in Design
The main Net Zero Energy Building Terms used in Designs are :
1,) Net Zero Energy Building Energy Models are virtual e models of the building which is based on building physics and it uses a baseline model and compares the energy savings with the proposed model. Interpreting the results will make the difference. Read the 10 types of energy saving model in this blog
The Energy performances are to be controlled through-out the delivery process tracking for net zero energy performance?The entire design team should interface with the energy model for energy modeling to be successfully achieved as an end to the energy model.
Inputs such as OTTV, RTTV, air con loads, temperature set points , outside ambient temperatures, and details about systems will help the energy model to be accurate.A white box model/shoe box model helps to analyze the daylight and energy performances. A white box model is a simple 3 d electronic model of a building without much details of the building.merely showing the overall shape of the building, and the insulation material will be shown.
These Net Zero Energy Building Energy Models can be created by Sketch up plug in such as IES Virtual Environment and Energy Plus and Open Studio.This model study is possible with VE( mass, window/wall ratios).In the future, the Thermal comfort models may be designed for designing purposes.Other Tools box that can be useful are–Weather Maker, sketch up, eQuest, IES Virtual Environment(VE), TRNSYS and THERM

2.) Energy-energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.
The types of Energy are – Kinetic Energy, Potential Energy, Mechanical Energy,Gravitational Energy, Nuclear Energy, Chemical Energy, Electricity Energy, Motion Energy, Thermal Energy, Radiant Energy and Sound Energy.
3.) Law of Thermodynamics states that:
a)Energy cannot be created or destroyed, the sum energy of the universe is constant.
b)Law of Entropy, that energy flow from hot to cold
4.) Power is the rate of doing work or transfer of energy, P=W/t, SI for power is Joules per sec(Watt), a LED using 1watt diode uses 1-watt energy for 1hour
5.) Horse Power is to measure mechanical power,
6.) Btu is heat used to raise the temperature by 1 pound of water by 1 degree F.MBtu is the power to cool and heat water for air con.
Megawatt hour is electrical energy
7.) Photo-voltaic Solar panels convert radiant energy to electrical energy and thermal energy.
